Create application server profiles

Create an application server profile so that we can make applications available to the Internet or to an intranet, typically using Java technology. We can create an application server profile using the Profile Management Tool.

Before using the Profile Management Tool, install the product files.

The Profile Management Tool is the graphical user interface for the manageprofiles command. See the description of the manageprofiles command for more information.

Provide enough system temporary space to create a profile. For information, read about the file system requirements for profiles.

When you launch the Profile Management Tool, the tool could lock up in the following situation for a non-root user: Log into a machine as root, use the SetPermissions utility to change the user from x to y. Assume that you are user x and log back into the machine. Launch the Profile Management Tool, click Profile Management Tool, and click Create. The next click after the click on Create could lock up the tool.

When we use the Profile Management Tool with the Motif graphical user interface on the Solaris operating system, the default size of the Profile Management Tool might be too small to view all the messages and buttons of the Profile Management Tool. To fix the problem, add the following lines to the app_server_root/.Xdefaults file: 

Eclipse*spacing:0
Eclipse*fontList:-misc-fixed-medium-r-normal-*-10-100-75-75-c-60-iso8859-1
After adding the lines, run the following command before launching the Profile Management Tool:

We can create profiles with the Profile Management Tool using the typical profile creation process or the advanced profile creation process. The typical profile creation process uses default settings and assigns unique port values. We can optionally set values as allowed. For the advanced profile creation process we can accept the default values, or specify our own values.

  1. Start the Profile Management Tool to create a new runtime environment.

    We can use one of the following ways to start the tool.

    • Issue the command to open the WebSphere Customization Toolbox directly from a command prompt; then, open the Profile Management Tool.

    • Select the WebSphere Customization Toolbox option from the First steps console; then, open the Profile Management Tool.
    • Use the Start menu to access the WebSphere Customization Toolbox; then, open the Profile Management Tool.
    • Use the Linux operating system menus used to start programs to start the WebSphere Customization Toolbox; then, open the Profile Management Tool.

  2. Click Create on the Profiles tab to create a new profile.

    The Profiles tab contains a list of profiles that have been created on your machine. No action can be done on a selected profile unless the profile can be augmented. The Augment button is greyed out unless a profile that you select can be augmented.

    The tool displays the Environment selection panel.

  3. Select Application server and click Next.

    The Profile creation options panel is displayed.

  4. If you selected Typical profile creation, then go to the step on administrative security.

  5. If you selected Advanced profile creation, then select the applications to deploy; and click Next.

    The tool displays the Profile name and location panel.

  6. Specify a name for the profile and the directory path for the profile directory, or accept the default values. Then, click Next.

    Profile naming guidelines: Double-byte characters are supported. The profile name can be any unique name with the following restrictions. Do not use any of the following characters when naming your profile:

    • Spaces
    • Special characters that are not supported within the name of a directory on your operating system, such as *&?
    • Slashes (/) or (\)

    We can create a application server using configuration settings that are optimized for a development environment by checking Create the server using the development template on the Profile name and location panel of the Advanced profile creation path. The development template reduces startup time and allows the server to run on less powerful hardware.

    Do not use the development template for production servers.

    The first profile that you create on a machine is the default profile. The default profile is the default target for commands issued from the bin directory in the product installation root. When only one profile exists on a machine, every command works on the single server process in the configuration. We can make another profile the default profile when we create that profile by checking Make this profile the default on the Profile name and location panel of the Advanced profile creation path. We can also make another profile the default profile using the manageprofiles command after you create the profile.

    When multiple profiles exist on a machine, certain commands require specified the profile to which the command applies if the profile is not the default profile. These commands use the -profileName parameter to identify which profile to address. You might find it easier to use the commands that are in the bin directory of each profile.

    Use these commands to query the command shell to determine the calling profile and to address these commands to the calling profile.

    The default profile name is <profile_type><profile_number>:

    • <profile_type> is a value of AppSrv, Dmgr, Custom, AdminAgent, JobMgr, or SecureProxySrv.
    • <profile_number> is a sequential number used to create a unique profile name

    The default profile directory is app_server_root/profiles, where app_server_root is the installation root.

    The default profile directory is app_server_root\profiles, where app_server_root is the installation root.


    Performance tuning setting: Select the performance-tuning setting that most closely matches the type of environment in which the application server will run.

    Standard

    The standard settings are the standard out-of-the-box default configuration settings that are optimized for general-purpose usage.

    Peak

    The peak settings are appropriate for a production environment where application changes are rare and optimal runtime performance is important.

    Development

    The development settings are appropriate for a development environment where frequent application updates are performed and system resources are at a minimum.

    Do not use the development settings for production servers.

  7. On the Node and host names panel, specify the characteristics for the application server, and click Next.

    Use unique names for each application server that you create.

    Reserved names: Avoid using reserved folder names as field values. The use of reserved folder names can cause unpredictable results. The following terms are reserved folder names:

    • cells
    • nodes
    • servers
    • clusters
    • applications
    • deployments

    Some default values in the following table are split on multiple lines for printing purposes.

    Field Name Default Value Constraints Description
    Node name 

    shortHostName
Node
NodeNumber
    where:

    • shortHostName is the short host name
    • NodeNumber is a sequential number starting at 01

    		Avoid using the reserved terms. Select any name you want. To help organize your installation, use a unique name if you plan to create more than one application server on the machine.
    Server name server1 Use a unique name for the application server. The name is a logical name for the application server.
    Host name

    The long form of the domain name server (DNS) name.

    		Addressable through your network. Use the DNS name or IP address of your machine to enable communication with your machine. See additional information about the host name following this table.

    Node name considerations:

    Directory path considerations:

    • The installation directory path must be less than or equal to 60 characters.
    • In the Profile Management Tool, fields for entering directory paths might not grey out when disabled and might have differing context menus from normal when we right-click them.

    Host name considerations:

    The host name is the network name for the physical machine on which the node is installed. The host name must resolve to a physical network node on the server. When multiple network cards exist in the server, the host name or IP address must resolve to one of the network cards. Remote nodes use the host name to connect to and communicate with this node. Selecting a host name that other machines can reach within your network is important. Do not use the generic identifier, localhost, for this value. Also, do not attempt to install WebSphere Application Server products on a machine with a host name that uses characters from a double-byte character set (DBCS). DBCS characters are not supported when used in the host name.

    If you define coexisting nodes on the same computer with unique IP addresses, then define each IP address in a domain name server (DNS) look-up table. Configuration files for standalone application servers do not provide domain name resolution for multiple IP addresses on a machine with a single network address.

    The value specified for the host name is used as the value of the hostName property in configuration documents for the standalone application server. Specify the host name value in one of the following formats:

    • Fully qualified domain name server (DNS) host name string, such as xmachine.manhattan.ibm.com
    • The default short DNS host name string, such as xmachine
    • Numeric IP address, such as 127.1.255.3

    The fully qualified DNS host name has the advantages of being unambiguous and flexible. You have the flexibility of changing the actual IP address for the host system without having to change the application server configuration. This value for the host name is particularly useful if you plan to change the IP address frequently when using Dynamic Host Configuration Protocol (DHCP) to assign IP addresses. A disadvantage of this format is dependency on DNS. If DNS is not available, then connectivity is compromised.

    The short host name is also dynamically resolvable. A short name format has the added function of being redefined in the local hosts file so the system can run the application server, even when disconnected from the network. To run disconnected, define the short name as the loopback address, 127.0.0.1, in the hosts file to run disconnected. A disadvantage of this format is a dependency on DNS for remote access. If DNS is not available, then connectivity is compromised.

    A numeric IP address has the advantage of not requiring name resolution through DNS. A remote node can connect to the node that you name with a numeric IP address without DNS being available. A disadvantage of this format is the numeric IP address is fixed. You must change the setting of the hostName property in Express configuration documents whenever you change the machine IP address. Therefore, do not use a numeric IP address if we use DHCP, or if you change IP addresses regularly. Another disadvantage of this format is that we cannot use the node if the host is disconnected from the network.

    After specifying application server characteristics, the tool displays the Administrative security panel.

  8. Optionally enable administrative security, and click Next.

    We can enable administrative security now during profile creation, or later from the console. If you enable administrative security now, then enter a user name and password to log onto the dmgr console.

    After specifying security characteristics, the tool displays the Security certificate panel if you previously selected Advanced profile creation.

  9. If you selected Typical profile creation at the beginning of these steps, go to the step that displays the Profile summary panel.
  10. Verify the ports specified for the standalone application server are unique, and click Next.

    If you chose not to deploy the dmgr console, then the dmgr console ports are disabled on the Ports panel.

    Port conflict resolution

    Ports are recognized as being in use if one of the following conditions exists:

    • The ports are assigned to a profile created from an installation that is performed by the current user.
    • The port is currently in use.

    Validation of ports occurs when we access the Port value assignment panel. Conflicts can still occur between the Port value assignment panel and the Profile creation complete panel because ports are not assigned until profile creation completes.

    If you suspect a port conflict, then we can investigate the port conflict after the profile is created. Determine the ports used during profile creation by examining the following files.

    • profile_root/properties/portdef.props file
    • profile_root\properties\portdef.props file

    Included in this file are the keys and values used in setting the ports. If you discover ports conflicts, then we can reassign ports manually. To reassign ports, run the updatePorts.ant file using the ws_ant script.

    The tool displays the Windows service definition panel if you are installing on a Windows operating system and the installation ID has the administrative group privilege. The tool displays the Linux service definition panel if you are installing on a supported Linux operating system and the ID that runs the Profile Management Tool is the root user.

  11. Choose whether to run the application server as a Windows service on a Windows operating system or as a Linux service on a Linux operating system, then click Next.

    • The Windows service definition panel is displayed for the Windows operating system only if the ID that installs the Windows service has the administrator group privilege. However, we can run the WASService.exe command to create the Windows service as long as the installer ID belongs to the administrator group. Read about automatically restarting server processes for more information.

      WAS v8.5 attempts to start Windows services for application server processes that are started by a startServer command. For example, if you configure an application server as a Windows service, and issue the startServer command, then the wasservice command attempts to start the defined service.

      If you chose to install a local system service, then we do not have to specify the user ID or password. If you create a specified user type of service, then specify the user ID and the password for the user who runs the service. The user must have Log on as a service authority for the service to run correctly. If the user does not have Log on as a service authority, then the Profile Management tool automatically adds the authority.

      To perform this profile creation task, the user ID must not contain spaces. In addition to belonging to the administrator group, the ID must also have the advanced user right of Log on as a service. The Installation program grants the user ID the advanced user right if the user ID does not already have the advanced user right and if the user ID belongs to the administrator group.

      We can also create other Windows services after the installation is complete to start other server processes. Read about automatically restarting server processes for more information.

      We can remove the Windows service that is added during profile creation during profile deletion. We can also remove the Windows service with the wasservice command.

      IPv6 considerations

      Profiles created to run as a Windows service fail to start when using Internet Protocol v6 (IPv6) if the service is configured to run as local system. Create a user-specific environment variable to enable IPv6. Since this environment variable is a user variable instead of a local system variable, only a Windows service that runs as that specific user can access this environment variable. By default, when a new profile is created and configured to run as a Windows service, the service is set to run as local system. When the Windows service for the product tries to run, the service is unable to access the user environment variable that specifies IPv6, and thus, tries to start as Internet Protocol Version 4 (IPv4). The server does not start correctly in this case. To resolve the problem, when creating the profile, specify the Windows service for the product runs with the same user ID from which the environment variable that specifies IPv6 is defined, instead of as local system.

      Default values for the Windows service

      The following default values for the Windows service definition panel exist:

      • The default is to run as a Windows service.
      • The service process is selected to run as a system account.
      • The user account is the current user name. User name requirements are the requirements the Windows operating system imposes for a user ID.
      • The startup type is automatic. The values for the startup type are those values the Windows operating system imposes. If you want a startup type other than automatic, we can either select another available option from the menu or change the startup type after you create the profile. We can also remove the created service after profile creation, and add it later with the desired startup type. Choose not to create a service at profile creation time and optionally create the service later with the desired startup type.

    • The Linux service definition panel is displayed if the current operating system is a supported version of Linux operating systems, and the current user has the appropriate permissions.

      WAS v8.5 attempts to start Linux services for application server processes that are started by a startServer command. For example, if you configure an application server as a Linux service and issue the startServer command, then the wasservice command attempts to start the defined service.

      By default, the product is not selected to run as a Linux service.

      To create the service, the user that runs the Profile Management Tool must be the root user. If you run the Profile Management Tool with a non-root user ID, then the Linux service definition panel is not displayed, and no service is created.

      When creating a Linux service, specify a user name from which the service runs.

      To delete a Linux service, the user must be the root user or have appropriate privileges for deleting the service. Otherwise, a removal script is created the root user can run to delete the service for the user.

    If you previously selected Advanced profile creation, the next panel displays the web server definition panel.

  12. For advanced profile creation, if you choose to include a web server definition in the profile now, specify the web server characteristics on the panels, and click Next until you complete the web server definition panels.

    If we use a web server to route requests to the product, then you need to include a web server definition. We can include the definition now, or define the web server to the product later. If you define the Web server definition during the creation of this profile, then we can install the web server and its plug-in after you create the profile. However, install both to the paths specified on the web server definition panels. If you define the web server to the product after you create this profile, then you must define the Web server in a separate profile.

    The tool displays the Profile Creation Summary panel.

  13. Click Create to create the application server, or click Back to change the characteristics of the application server.

    The Profile creation progress panel, which shows the configuration commands that are running, is displayed.

    When the profile creation completes, the tool displays the Profile creation complete panel.

  14. Optionally, select Launch the First steps console. Click Finish to exit.

    With the First steps console, we can create additional profiles and start the application server.


Results

We created an application server profile. The node within the profile has an application server named server1.
