Prerequisites and pre-installation tasks for ITCAM for WAS on Linux and UNIX systems

Supported operating system and appserver combinations


Supported JDKs for the ITCAM for WAS

The supported JDKs for the ITCAM for WAS are the same as the supported JDKs for the particular appserver you will be monitoring.


Additional requirements for Linux and UNIX operating system

ITCAM for WAS must be installed on the same machine as the appserver you will be monitoring.

ITCAM for WAS can not be configured for an appserver instance where the Data Collector for ITCAM for WebSphere 6.1, ITCAM for Web Resources 6.2, or ITCAM Agent for WebSphere Applications 7.1 (a component of ITCAM for Application Diagnostics) is configured. However, these products can be installed on the same host and configured for different appserver instances.


Prerequisite libraries

The ITCAM for WAS installer and configuration utility require several libraries to run in graphics mode.

On Linux systems, the following additional libraries are required:

If the libraries are not available, the installer and configuration utility will fail. You can use silent installation and configuration without installing the libraries. The following packages are required in certain Linux distributions:

Tasks to install ITCAM for WAS v7 on Linux and UNIX

  1. Obtain the installation images.

  2. Install using one of the following methods...


UNIX Permissions


Additional requirements when using the appserver ID (non-root owner ID)

If the appserver instance has a non-root owner ID, use the same owner ID as the appserver to install ITCAM for WAS. To use that ID, first perform the following procedure to avoid communication problems:

  1. Make sure that the appserver owner ID can write to the DC_home directory, which must be empty. This will be specified during the installation.

  2. Make sure the user has read and write privileges to one of the following system temporary directories. These directories will be used by the InstallShield portion of the installation program

    Operating system Directory
    Solaris or HP-UX If it exists: /var/tmp/ibm_am_installer_dc, If not: /var/tmp
    Linux and all other UNIX platforms If it exists: /tmp/ibm_am_installer_dc. If not: /tmp

    The InstallShield portion of the installation program does not need to actually write to this directory. There are procedures to perform before running the installation program if you want to specify a different temporary directory for InstallShield to write to.

  3. Make sure the user is able to log to /var/ibm/tivoli.

    You might have to create this directory as root and use the chown command to change ownership to the user.

    The installation and configuration programs do not need to actually write to this directory as you use installation program to specify a different log directory to write to.

  4. Give user read and write privileges to...

    • WAS_HOME/profiles/profile/logs
    • WAS_HOME/profiles/profile/logs/wsadmin.traceout
    • WAS_HOME /profiles/profile/logs/wsadmin.valout

If WAS was installed by root and the appserver instance created from that installation of WAS was created and is owned by a non-root user...

  1. As the root user, run...

      chown -R wasuser:wasgroup WAS_HOME/properties/version/history
    chown wasuser:wasgroup WAS_HOME/properties/version

    ...where wasuser and wasgroup are the user and group for the appserver instance.

  2. As the non-root user...

      ./versioninfo.sh

If after running the versioninfo.sh command, you encounter information about the appserver version (instead of an error message), you know that you have performed the chown commands successfully.


Checking the heap size

On each WAS appserver, verify heap is not less than 384 MB. From the WAS console.

Set Maximum Heap Size to at least 384 MB

For Linux in a Network Deployment environment, it is a requirement (not merely a recommendation) that you increase the Maximum Heap Size to a value above 256 ; otherwise, the installation might fail with the following error message:


HP-UX: tuning HotSpot JVM garbage collection

For HotSpot JVM, the default NewSize and MaxNewSize might be too small for some applications if these applications allocate large numbers of short living objects. Some tuning is recommended for an application that allocates many short living objects:

Also, the default MaxPermSize might be small for some applications, too. It is recommended to use

NewSize, MaxNewSize, and MaxPermSize should be changed based on the Maximum (-Xmx) and Minimum (-Xms) heap settings of the JVM.


Adjusting ports for firewalls or for use with other applications

At various times during the installation, specify or accept the defaults for port numbers used by ITCAM for WAS to communicate with the appserver using SOAP or RMI. Make sure that you record the correct port, and that the firewall does not prevent communication on this port from ITCAM for WAS to the appserver.

For a Network Deployment environment, ITCAM for WAS will need to use the SOAP or RMI port to communicate with the dmgr, which is usually located on a different host. In this case, take special care that the firewall does not block communication on this port. Consult the documentation for your firewall program to determine which ports are being blocked by your firewall.


Making sure there are no invalid mounted file systems

There might be file systems that are specified as mounted in /etc/filesystems that are not actually mounted or have lost connection with the ITCAM for WAS machine. Verify the following commands can be run successfully and without error messages:

If this not the the case, the installation will hang without producing any error messages. To prevent this, either mount all file systems listed, or comment out all files systems that are not mounted. On Linux this file is called /etc/fstab.


Mounting the ITCAM for WAS DVD on HP-UX

to use the DVD to install ITCAM for WAS on HP-UX, run the following command when mounting the DVD:


Enable user ID and password input from sas.client.props for RMI connector types

If WAS global security is enabled, to have the configuration program retrieve the RMI connection user ID and password from sas.client.props, instead of entering them in the panel or as silent configuration option, edit...

...and set...

Encrypt the password:


Enable user ID and password input from soap.client.props for SOAP connector types

If WAS global security is enabled, to have the configuration program retrieve the SOAP connection user ID and password from soap.client.props, instead of entering them in the panel or as silent configuration option, edit...

...and set...

Encrypt the password:


Gathering information about values specified during installation and configuration

An ITCAM for WAS installation cannot span over multiple hosts. Install ITCAM for WAS separately on each host, and configure it for each appserver instance.

For a Network Deployment environment, we install on nodes, supplying the host name of the dmgr. We do not need to install or configure ITCAM for WAS on the dmgr itself.

By default, the installer will create log files in...

For GUI installation and configuration, there are three types of fields that appear in the installer:

Prefilled, editable Either accept the default that is provided or enter your own value.
Blank You must enter a value of your own.
Prefilled, noneditable You cannot change the provided value. These fields will not be mentioned in the steps that follow.

The installation and configuration programs will not accept values for directory paths if the following special characters are included: \u `!@#$*()+=[]{}|:;’"<>,?

The InstallShield portion of the installation program writes to one of the following directories...

OS Directory
Solaris or HP-UX If it exists: /var/tmp/ibm_am_installer_dc. If not, /var/tmp
Linux and all other UNIX platforms If it exists: /tmp/ibm_am_installer_dc. If not, /tmp

To change temporary file location, do not use launchpad.sh, instead, run the executable directly with the following option:

For example:

The user for the installation should have read, write, and execute privileges to this directory.

The installation program will write to the following log directory by default:

To change log directory, do not use launchpad.sh, instead, run the executable directly with the following option:

For example:

The user for the installation should have read and write privileges to this directory.


GUI installation and configuration of ITCAM for WAS on UNIX and Linux

  1. If running the installation from a remote computer, run...

      xhost + hostname

    ...on the computer where you are sitting, where hostname is the fully qualified host name of the computer on which ITCAM for WAS is being installed.

  2. Log on to the computer on which you want to install ITCAM for WAS using the user that has permissions to perform the installation.

  3. If running the installation from a remote computer, run...

      export DISPLAY=local_machine:0.0

    ...where local_machine is the fully qualified host name of the computer where you are sitting.

    If running the installation from the computer where ITCAM for WAS is being installed, enter...

      export DISPLAY=localhost:0.0

  4. Start the instance of the appserver that will be monitored by ITCAM for WAS.

    In a Network Deployment environment start the Node Agent and dmgr before the installation. Starting the instance of the appserver is not necessary.

  5. Start the installation program using either...

    • WAS LaunchPad

    • ITCAM for WAS installation image...

        HP-UX setup_DC_hp11.bin
        setup_DC_hp11_ia.bin (HP-UX IA 64-bit)

  6. The installation program displays a window asking for a path for writing log files.

    Accept the default or click the Browse button to select a different path. The current user must have write permissions for this path. The first window for the installation program opens, displaying the Welcome window.

    If the installation program detects that your computer does not match the basic prerequisites for starting the installation, a failure window opens instead of the Welcome window.

  7. Click Next to show the Choose Destination window to select the installation directory.

  8. Accept the default installation directory path in the Product Installation Directory field, or click Browse to change this path.

    You cannot install ITCAM for WAS in a directory path that includes the following types of characters: Traditional Chinese, Simplified Chinese, Japanese, Korean, Spanish special characters, German special characters, Portuguese Brazilian special characters, French special characters, Italian special characters.

    If you specify a directory that does not exist, the installation program creates the directory.

  9. Click Next to accept the default installation directory path in the Directory Name field; you can also change this path by typing or browsing to a different directory and then click Next.

  10. Click Next to open the Generate Response File window.

  11. To install ITCAM for WAS on this computer, select...

      Install the Data Collector on this computer

    To create a response file for a subsequent silent installation, select...

Silent installation and configuration of ITCAM for WAS on UNIX and Linux

You have the option to only install ITCAM for WAS, both install and configure ITCAM for WAS, or only configure ITCAM for WAS using this procedure. If you only want to configure ITCAM for WAS, perform this procedure after ITCAM for WAS has been installed.

  1. Log on to the computer on which you want to install and configure ITCAM for WAS as a user with the proper permissions.

  2. Start the instance of the appserver that will be monitored by ITCAM for WAS.

    If you are in a Network Deployment environment, before the configuration program applies the configuration, it will perform an autosynchronization between the Node Agent and dmgr. You must start the Node Agent and dmgr before the installation. Starting the instance of the appserver is not necessary.

  3. Check to see if the latest level of maintenance, such as fix packs or interim fixes, needs to be applied.

    If there is no maintenance to apply, you can perform both the installation and configuration by running the executable file once and using one response file. If there is maintenance apply, run the installation and configuration separately. After performing the silent installation, and before performing the silent configuration, apply the latest level of maintenance.

  4. Perform one of the following procedures:

    • Specify configuration options in...

    • Use response files created by the GUI installation and configuration programs.

      To perform both a silent installation and a silent configuration, make one response file from two generated response files:

      1. Select...

          Save settings to the response file

        ...during the GUI installation and the GUI configuration.

      2. With a text editor, copy and paste the contents of the response file generated from the installation program into the response file generated by the configuration program.

      3. Save the newly created response file with a unique name or in another location.

        If you are performing only the installation, options for the configuration will be ignored when running the silent installation. If you are performing only the configuration, options for the installation will be ignored when running the silent configuration.

  5. Perform one of the following procedures:

    Script to install, or install and configure Script to configure only
    IBM AIX setup_DC_aix.bin
    Solaris setup_DC_sol.bin
    Linux setup_DC_lin.bin
    HP-UX setup_DC_hp11.bin
    		config_dc.sh

  6. Run...

      ./script.sh -silent [-is:log [ /path/to/file.log ]] [ configuration_option ...] -options /path/to/response.opt
    Examples:

      ./setup_DC_lin390.bin -silent -is:log /opt/tmp/DClog.txt -V DC_ASL_PORT="8885" -options /opt/silent/DC6.opt
      ./config_dc.sh -silent -V DC_ASL_PORT="8885" -options /opt/silent/DC6.opt

    Configuration options specified in the response file take precedence over those entered in the command line. For a particular command-line configuration option to take effect, nullify the option in the response file by commenting it out with a pound sign (#).

    If you are performing a silent configuration (after ITCAM for WAS has been installed), you cannot use the -is option. Instead run the command in the following way:

      ./config_dc.sh -silent [ configuration_option ...] -options /path/to/reponse.opt

    For example:

      ./config_dc.sh -silent -V DC_ASL_PORT="8885" -options /opt/silent/DC6.opt

  7. If you have performed only a silent installation (LAUNCH_CONFIG="false"), to verify install success, look at...

      /var/ibm/tivoli/common/CYN/trace-install.log

    If you have just performed a silent installation, before executing a silent configuration, apply any required maintenance.


Additional configuration tasks - UNIX and Linux

  1. Enable ITCAM for WAS in the IBM WAS administrative console.

  2. Restart the instance of the appserver that will be monitored by ITCAM for WAS.

    If the appserver fails to start up, ITCAM for WAS configuration has failed.

    • After the configuration, the appserver fails to restart.
    • During a GUI configuration, the summary panel for the Configuration Tool indicates the configuration has failed.
    • During a silent configuration, the command line indicates a message that the configuration has failed.
    • After the configuration, there are messages in the log file that indicate configuration has failed.

    If ITCAM for WAS configuration has failed, see Appendix F, "What to do if ITCAM for WAS configuration fails"

  3. Start ITCAM for WAS in the IBM WAS administrative console.

  4. Perform the tasks described in each of the following sections, if applicable


If you used root for ITCAM for WAS installation and the appserver is not owned and operated by the root ID

The installer will have the authority to use whatever directories and files it requires. The installer will be able to find most appserver installations on the machine. But, if the appserver is not owned and operated by root ID, you will need to finish the following tasks in order for ITCAM for WAS to work correctly:

  1. Change ownership to root to appserver owner ID:

    ul> chown -R wasOwnerId:wasGroupId DC_home

  2. Verify you can write to CYN directory...

      chown -R wasOwnerId:wasGroupId /var/ibm/tivoli/common/CYN


Additional procedure for Security Enhanced Linux (SELinux)

After installing ITCAM for WAS on SELinux, for example Red Hat Enterprise Linux Version 5 or SUSE Linux Enterprise Server Version 11, perform an additional procedure to identify the Data Collector shared libraries.

Unconfiguring ITCAM for WAS using the Configuration Tool on Windows, UNIX, and Linux

    1. On UNIX or Linux, if running the uninstallation from a remote computer, enter

      xhost + hostname

    ...on the computer where you are sitting. Where hostname is the fully qualified host name of the computer on which ITCAM for WAS is being uninstalled.

  1. Log on to the computer that you want to uninstall ITCAM for WAS using the same user name that performed the installation.

  2. On UNIX or Linux, export the DISPLAY variable using one of the following options:

    • If running the unconfiguration from a remote computer...

        export DISPLAY=local_machine:0.0

      ...where local_machine is the fully qualified host name of the computer where you are sitting.

    • If running the unconfiguration from the computer where ITCAM for WAS was installed...

        export DISPLAY=localhost:0.0

  3. Verify the instance of the appserver being monitored by ITCAM for WAS is running.

      cd WAS_HOME/profiles/profile/bin
      //serverStatus.sh server_name

    If you are in a Network Deployment environment, before the configuration program applies the unconfiguration, it synchronize nodes.

  4. Browse to the installation directory for ITCAM for WAS and change to the config_dc directory.

  5. Run config_dc.sh

    The Configuration Tool opens, displaying the Welcome panel.

    The Configuration Tool depends on...

      DC_home/config_dc/dcInputs.txt

    To restore the original PMI settings that existed before the ITCAM for WAS configuration only for particular appserver instances, select Unconfigure each appserver separately

    Then click Next to start the unconfiguration process

  11. The unconfiguration program validates the connection between ITCAM for WAS and the appserver using the information entered when you configured ITCAM for WAS. If the user name, password, or cell name have changed since configuration, the validation will fail. If validation fails, a window displays in which you must enter information about ITCAM for WAS and appserver communication.

    A panel with summary information indicating the results of the unconfiguration procedure displays


Silent unconfiguration of ITCAM for WAS on Windows, UNIX, and Linux

  1. Verify the instance of the appserver being monitored by ITCAM for WAS is running.

      cd WAS_HOME/profiles/profile/bin
      /serverStatus.sh server_name

    If you are in a Network Deployment environment, start node agents and dmgr, then synchronize all nodes. Starting the instance of the appserver is not necessary.

  2. Specify configuration options in the DC_unconfig.opt response file template and save the file.

      cd DC_home /config_dc directory.
      ./config_dc.sh -silent [configuration_option...] -options response_file

    For example...

      ./config_dc.sh -silent -V DC_CCUC_UNCONFIG=true -V DC_ASL_SOAPPORT ="8885" -options /opt/silent /DC6.opt

      uninstaller.exe

    Repeat steps 7


Unconfiguring ITCAM for WAS in prompt mode

  1. If WebSphere Global Security is enabled, log in as a WebSphere administrator who will be able to administer the appserver configuration.

  2. Perform one of the following procedures:

    • If you are running the appserver in a Network Deployment environment, ensure that the dmgr and the node agent are running.
    • If you are running the appserver in a non-Network Deployment environment, ensure that the instance of the appserver that is being monitored by ITCAM for WAS is running.

  3. To set any of the configuration options as environment variables before running the unconfiguration script, export the environment variables. For example...

      export ITCAM_CONNTYPE=RMI
      export ITCAM_CLEANUP=y

    By exporting these variables, the unconfig.sh script will use them as the new default values. You will not need to enter a value (simply press Enter) when you are prompted for them.

  4. Run the following command from the

      cd /u/ecam/bin
      ./unconfig.sh [options]

    The unconfig.sh script will use command-line values as the new default values. You will not need to enter a value (simply press Enter) when you are prompted for them. You will be prompted for the path of

    By exporting these variables, the unconfig.sh script will use them as the new default values. You will not need to enter a value (simply press Enter) when you are prompted for them.

      cd /u/ecam/bin
      ./unconfig.sh [options]

    The default path for the location of the script is u/ecam/bin.

    By setting options in the command line, the unconfig.sh script will use them as the new default values. You will not need to enter a value (simply press Enter) when you are prompted for them. You will be prompted for the path of WAS_HOME :

      Enter the path of the WAS user install root [/u/ WAS7000]:

  5. Enter the HFS path name of WAS_HOME and press Enter.

    The configuration script uses this path to search for the wsadmin.sh script that was used to configure the target appserver for ITCAM monitoring during the configuration.

    You should respond with a valid HFS path name, for example,

      /u/ WAS7000

    You will be prompted to select one of the discovered occurrences of the wsadmin.sh script:

      Found wsadmin.sh in the following locations:


      1) /u/was7000/DeployMgr/AppServer/bin/wsadmin.sh
      2) /u/was7000/DeployMgr/AppServer/profiles/default/bin/wsadmin.sh
      2) /u/was7000/DeployMgr/DeploymentManager/bin/wsadmin.sh

    Enter the number of the wsadmin to use for unconfiguration

  6. Enter the number that corresponds to the path for the appropriate wsadmin.sh script and press Enter. The script will use the wsadmin.sh that you selected to find all server instances that are running on this node. Then you will be prompted to select one of the discovered instances of the appserver:

      1) IBM123
      2) IBM124
      3) IBM125
      4) IBMabc

    Enter the number of the server to select:

  7. Enter the number that corresponds to the appropriate instance of the appserver that you want to unconfigure and press Enter. You will be prompted whether you want to remove the runtime directory for the appserver instance that is being unconfigured: 

    Server "IBM123" has been selected

    The runtime directory for IBM123 is:

    /u/ecam/runtime/was70.TIVOLI.IBM123

Do you wish to remove this directory? (y|n) [n]:

  8. Enter y or n and press Enter. Entering y indicates that you want to remove the existing runtime directory for the appserver instance. Whether you enter y or enter n, the WAS customization done for ITCAM for WAS will be removed.

    You will be prompted whether you want to remove ITCAM statements from the server.policy file

    ITCAM configuration adds statements to the Java 2 security file server.policy. Since this policy file is shared by all servers on this node, you should only remove these statements when the last server configured for ITCAM is unconfigured.

      Do you wish to remove ITCAM changes to the server.policy file? (y|n) [n]:

    Enter y if you have unconfigured ITCAM for WAS for all server instances on this node. Otherwise. enter n . The script will unconfigure ITCAM for WAS.

    For successful unconfiguration, look for messages similar to the following:

      Successfully unconfigured data collector for server IBM123

    The runtime unconfiguration script creates a log of all the unconfiguration operations that it performs. You can review the log for any error conditions, and you might be requested to provide the log contents to IBM Software Support. The log file is called unconfig.log and is located in the runtime directory under config_home . For example...

      /u/ecam/runtime/unconfig.log

    ITCAM for WAS v7 JDK is the same the monitored WAS appservers.

    Co-locate ITCAM for WAS on the same host as the WAS appserver to be monitored.

    Do not configure ITCAM for WAS for an appserver instance where any of the following are installed...

    • ITCAM Agent for WAS 7.1 (Component of ITCAM for Application Diagnostics)
    • ITCAM for Web Resources 6.2
    • Data Collector for ITCAM for WebSphere 6.1

    Note that these products can be co-located on the same host as ITCAM for WAS v7 if they are configured for different appserver instances.


    Windows Permissions

    The user who installs ITCAM for WAS must have read, write, and execute privileges on the appserver.

    Administrator privileges are not required unless the appserver is owned by a user with administrator privileges.

    The appserver instance owner ID must have write permission to the directory where the installer creates log files. Default is

      C:\IBM\tivoli\common\CYN\logs


    Checking the heap size

    Log on to the IBM WAS administrative console, and for each appserver, navigate to...

      Server | Application Servers | server_name | Configuration | Server Infrastructure | Java and Process Management | Process Definition | Additional Properties: Java Virtual Machine

    ...and set value for Maximum Heap Size to at least 384 MB.


    Adjusting ports for firewalls or for use with other applications

    Verify firewalls do not prevent communication on the SOAP and RMI ports ITCAM for WAS uses to communicate with the appserver dmgr.


    Enable user ID and password input from sas.client.props for RMI connector types

    1. Edit...

        WAS_HOME/profiles/profile/properties/sas.client.props

    2. Set the following properties...

        com.ibm.CORBA.loginSource=properties

    Information to know before the installation

    For an example of the values you may need to provide, see "Options for installing and configuring ITCAM for WAS"

    An ITCAM for WAS installation cannot span over multiple hosts. Install ITCAM for WAS separately on each host, and configure it for each appserver instance.

    For a Network Deployment environment, for node configuration, on each node, we supply the host name of the dmgr. We do not need to install or configure ITCAM for WAS Application Server on the dmgr itself.

    For a silent installation, copy the installation images to a hard disk.

    By default, the installer creates log files in:

      C:\IBM\tivoli\common\CYN\logs\trace-install.log

    For GUI installation and configuration, there are three types of fields in the installer:

      Prefilled, editable Either accept the default provided, or enter your own value.
      Blank Must enter a value of your own.
      Prefilled, noneditable Cannot change the provided value. These fields are not mentioned in the steps that follow.

    The installation and configuration programs do not accept values for directory paths if the following special characters are included:

      \u `!@#$*()+=[]{}|:;’"<>,?

Silent installation and configuration of ITCAM for WAS on Windows

Specify the location of a response file when you run the silent installation and configuration from a command line.

You have the option to only install ITCAM for WAS, both install and configure ITCAM for WAS, or only configure ITCAM for WAS. You can run the installation and configuration separately.

  1. Log on to the computer on which you want to install and configure ITCAM for WAS as a user with the proper permissions.

  2. Start the instance of the appserver that will be monitored by ITCAM for WAS.

    If you are in a Network Deployment environment start the Node Agent and the dmgr before the installation. Starting the instance of the appserver is not necessary.

  3. If Terminal Services is enabled on Windows 2003 Server, put the server into installation mode.

      change user/install

    Ignore the following message:

      Install mode does not apply to a Terminal server configured for remote administration

  4. Verify if latest level of maintenance (fix packs or interim fixes) needs to be applied

  5. You can either specify configuration options in...

      installation_image_directory/ilent/DC_was.opt

    ...or you can use response files created by the GUI installation programs. To perform both a silent installation and silent configuration, make one response file from two generated response files, during the GUI installation and configuration, select...

      Save settings to the response file

    ...and then, with a text editor, copy and paste the contents of the response file generated from the installation program into the response file generated by the configuration program. Save the newly created response file with a unique name or in another location.

  6. If you are performing only the installation, options for the configuration will be ignored when running the silent installation. If you are performing only the configuration, options for the installation will be ignored when running the silent configuration.

  7. To install, or install and configure, ITCAM for WAS, run setup_DC_w32.exe. To only configure ITCAM for WAS, run config_dc.bat

      setup_DC_w32.exe -silent [-is:log [ /path/to/file.log ]] [ configuration_option ...] -options /path/to/response.opt

    ...or...

      config_dc.bat -silent [-is:log [ /path/to/file.log ]] [ configuration_option ...] -options /path/to/response.opt

    ...where...

    log_file_name Path and name of the log file that the silent installer will write to. Wrap path in double-quotes (") if it contains spaces.
    configuration_option One or more configuration options not included in the response file.
    response_file

    Examples...

      setup_DC_w32.exe -silent -is:log "C:\log\DClog.txt" -V DC_ASL_PORT="8885" -options C:\itcam\images\silent\DC6.opt

      config_dc.bat -silent -V DC_ASL_PORT="8885" -options C:\itcam\images\silent\DC6.opt

    Configuration options specified in the response file take precedence over those entered in the command line. For a particular command-line configuration option to take effect, first nullify that option in the response file by commenting it out with a pound sign (#).

    If you are performing a silent configuration (after ITCAM for WAS has been installed), you cannot use the -is option. Instead run the command in the following way:

      config_dc.bat -silent [ configuration_option ...] -options response_file

    For example:

      config_dc.bat -silent -V DC_ASL_PORT="8885" -options C:\itcam\images\silent \DC6.op

  8. If you have performed only a silent installation (LAUNCH_CONFIG="false"), to verify whether the installation was successful, check...

Counters displayed in the Tivoli Performance Viewer

Enabling counters allows data to be displayed in the TPV. You can choose to display the particular data by enabling selected counters. The data will not display when the correlative counters are disabled.

Counter Description
RequestCount Number of requests completed since the counter was enabled or reset.
AverageResponseTime Average response time of requests in milliseconds.
MinimumResponseTime Fastest response time since the counter was enabled or reset in milliseconds. Available only at the instance level.
MaximumResponseTime Slowest response time since the counter was enabled or reset in milliseconds. Available only at the instance level.
LastMinuteAverageResponseTime Average response time of requests completed in the last minute in milliseconds
90%ResponseTime 90% median of requests in milliseconds. Maximum limit on the number of requests' response time stored to calculate the 90% response time can be set by defining....

    eCAM.90Percent.buffer.limit

...in....

Default is 50. Available only at the instance level. The 90% median is calculated by taking the sample at the 90% of the total samples. The formula to calculate the 90% median sample is...

    (number of samples - 1) * 0.9

For example, if the current sample size is 31 (from 0 - 30)...

    (31 - 1) * 0.9 = 27th

If the result is not an integer, like when current sample size is 32...

    (32 - 1) * 0.9 = 27.9th

This will be done by returning 10% of the 27th sample and 90% of the 28th sample.

AverageCPUUsage Average CPU usage of requests in milliseconds.
MinimumCPUUsage Least intensive CPU usage since the counter was enabled or reset in milliseconds. Available only at the instance level.
MaximumCPUUsage Most intensive CPU usage since the counter was enabled or reset in milliseconds. Available only at the instance level.
LastMinuteAverageCPUUsage Average CPU usage of requests completed in the last minute in milliseconds.
90%CPUUsage 90% median of requests in milliseconds. The maximum limit on the number of requests' CPU usage stored to calculate the 90% CPU usage can be set by defining...

    eCAM.90Percent.buffer.limit

...in...

Default is 50. Available only at the instance level. The 90% median is calculated by taking the sample at the 90% of the total samples. The formula to calculate the 90% median sample is...

    (number of samples - 1) * 0.9

For example, if the current sample size is 31 (from 0 - 30)...

    (31 - 1) * 0.9 = 27th


Appendix D. ITCAM for WAS configuration parameters

Edit...

...and set paramters in format: parameter =value

Do not change any settings in this file, except the settings listed below. If the file does not exist, create it. Restart the appserver after the parameters are changed

Configuration parameter Description
eCAM.90Percent.buffer.limit Number of sample used to calculate 90% metrics.
eCAM.PMI.Threadpool.size Thread pool size to update the PMI statistics. Updating the PMI statistics is decoupled from the application thread so it will not lengthen the application response time. The default value is 2. If the thread pool size is too small, updating the PMI statistics will slow down and more memory will be used. Unless the appserver is running out of memory, there is no need to fine tune this parameter.
eCAM.memory.limit Amount of memory in Megabytes that the ITCAM for WAS will use. Default is 20. When the memory limit is reached, new PMI statistics will not be created. New applications and requests will not show up in the PMI. An error message will be logged in the ITCAM log file...

    Exceeding memory limit defined in eCAM.memory.limit=size limit New counter will not be created, please increase memory limit
eCAM.disable.BCI When true, ITCAM for WAS will disable the BCI engine when it first starts. Used to reduce the memory usage of the ITCAM for WAS. Default is true


Appendix E. Specify silent values on Windows, UNIX, and Linux

Requirements for a response file

Response files preserve configuration data for an installation, configuration, or unconfiguration, so that you can identify configuration details at a later date. The following is general information and applies to any response file you create for ITCAM for WAS.

Appendix F. What to do if ITCAM for WAS configuration fails

You know the ITCAM for WAS (ITCAM for WAS) configuration has failed if any of the following has occurred:

If ITCAM for WAS configuration has failed, you can do the following to try to complete the configuration successfully:

  1. Restore the appserver configuration that you had before attempting the failed configuration.

  2. Run the GUI or silent configuration again


Restoring the appserver configuration after a failed ITCAM for WAS configuration

These instructions apply only to the Windows, UNIX, and Linux platforms.

If the appserver fails to start up, you can use the restoreConfig command to restore the appserver configuration. Perform one of the following procedures:

In a non-Network Deployment environment:

  1. Locate the backup configuration file that was created in...

      DC_home/config_dc/backup

  2. Stop all instances of appservers.

  3. Run the restoreConfig command...

      cd Appserver_home/profiles/profile/bin
      ./restoreConfig.sh DC_home/config_dc/backup/backup_file

    For example...

      ./restoreConfig.sh /opt/IBM/itcam/WebSphere/DC/config_dc/backup/WebSphereConfig_2008-04-22.zip

  4. Restart the instance of appserver that is being monitored by the Data Collector.

In a Network Deployment environment:

  1. Locate the backup configuration file that was created in the DC_home/config_dc/backup directory.

  2. Stop all instances of appservers.

  3. Run the restoreConfig command

      cd Appserver_home/profiles/profile/bin
      ./restoreConfig.sh DC_home/config_dc/backup/backup_file -location temp_directory

    For example...

      ./restoreConfig.sh /opt/IBM/itcam/WebSphere/DC/config_dc/backup/WebSphereConfig_2008-04-22.zip -location /tmp/restore


Enable privacy filtering

Used to filter out SQL, cookie, and HTTP Request query strings. When this property is set to true, these data are not collected by ITCAM for WAS.

  1. Stop the appserver instance that is being monitored by ITCAM for WAS.

  2. Edit...

      install_home/runtime/appserver_version.node.server_name/appserver_version.node.server_name.datacollector.properties

    ...and set...

      secure.filter.on=true

  3. Start the appserver instance that is being monitored by ITCAM for WAS.

The following statement is printed out to the ITCAM for WAS log when privacy filtering is properly configured:


Appendix H. Using regular expressions

Regular expressions are sets of symbols and characters that are used to match patterns of text. You can use regular expressions to search specific IP addresses across your Web environment. Regular expressions also enable you to search a simple, fixed URI or a complex URI pattern that matches one or more groups of transactions.


Regular expressions library

An extensive library of regular expression characters and operators is available for your URI filters and IP address specifications. The International Components for Unicode (ICU) open-source development project provides this library for your use. The next section provides the most frequently used expressions for this product. However, you can refer to the following Web page for a full description of the ICU regular expression library and an explanation of how to use the characters and operators for complex expressions: http://oss.software.ibm.com/icu/userguide/ regexp.html


Frequently used regular expressions

The following list highlights characters and operators most frequently used in regular expressions:

\ Quotes the character that follows it, which treats that character as a literal character or operator (not a regular expression). When you want the following characters to be treated as literal, precede them with a backslash:

    *?+[(){}^$|\./

In other words, use a backslash followed by a forward slash ( \/) to include a forward slash in a URI filter. Use a backslash followed by a period ( \.) to include a period in a URI filter.

Example: to specify the URI pattern http://www.ibm.com/, use the following regular expression:

    http:\/\/www\.ibm\.com\/

To specify all URIs that begin with http://www.ibm.com/, use the following regular expression:

    http:\/\/www\.ibm\.com\/.*
. Matches any one character. Example : to match both ibm2 and ibm3 within a string, use ibm . such as in the following example:

    http:\/\/www\.ibm.\.com\/
(?: ... ) Non-capturing parentheses. Groups the included pattern, but does not provide capturing of matching text. Somewhat more efficient than capturing parentheses. Example: you can use the non-capturing parenthesis to group expressions to form more complicated regular expressions. To match a URI that starts with one of the following:

    http://www.ibm.com/marketing/

or

    http://www.ibm.com/sales/

...you would do a grouping with a pipe sign (|) (represents or):

    http://www.ibm.com/(?:marketing)|(?:sales)/
* Matches the preceding element zero or more times. You must quote this character. Example : the expression, ca*t, matches cat, caat, ct, and caaaaat. The term cabt, would not return as a match.


Specify exclusions with the bang (!) operator (Quality of Service listening policies only)

Note: This section applies to the entry of URI and client IP filters for Quality of Service listening policies only.

You can use an exclamation point ( !), also called the bang operator, to filter out transactions that might match the regular expressions already entered, but that should not be considered valid transactions for this listening policy. These exclusions are considered negative filters. You can enter these exclusions as additional URI or client IP filters. The formatting of these additional filters is as follows:
