data collector for WebLogic server instance cannot be unconfigured after the listening port of the WebLogic domain administration server is changed

The problem: WebLogic server instance cannot be unconfigured after the listening port of the WebLogic domain administration server is changed. During the unconfiguration process, the following message is reported:

Cannot connect to weblogic server, please make sure the server is running, 
and check host/port parameters.
If connecting to weblogic over SSL, please check SSL client CA trust keystore file, 
and client certification files/types/password also.

The solution: Perform the following steps to unconfigure the Data Collector manually:

1. From the administration console of the WebLogic domain administration server, remove the WebLogic server instance from the target server list of Startup Class AM Startup. If the server list of Startup Class AM Startup is empty, it can be removed as well.

2. From the administration console of the WebLogic domain administration server, remove the WebLogic server instance from the target server list of Shutdown Class AM Shutdown. If the server list of Shutdown Class AM Shutdown is empty, it can be removed as well.

3. Stop the WebLogic server instance.

4. Remove ITCAM data collector JVM arguments from the WebLogic server instance startup script.

   • If the WebLogic server instance is started by a script file or is run as a Windows Service:

     1. Open the startup script file.

     2. Search and locate the lines with the keywords "DC for Weblogic support--begin"and "DC for Weblogic support--end" and delete all the content between the above two lines from the file.

   • If the WebLogic server instance is started from the NodeManager:

     1. Open WebLogic administration console in a browser. Navigate to the server instance's Configuration panel.

     2. Click the table Remote Start (WebLogic 8) or Server Start (WebLogic 9 or 10)

     3. For WebLogic 8, remove the following arguments from Arguments:

        -Xbootclasspath/p:DC_home/toolkit/…
        -DCCLOG_COMMON_DIR=...
        -Xrunam_sun(ibm/bea)_14:...
        -Dcom.ibm.tivoli.jiti.injector.IProbeInjectorManager=...
        -Dcom.ibm.tivoli.jiti.injector.ProbeInjectorManagerChain.
            primaryInjectorFile=...

     4. For WebLogic 9 or 10, remove the following arguments from Arguments:

        -Xbootclasspath/p:DC_home/toolkit/…
        -DCCLOG_COMMON_DIR=…
        -agentlib:am_sun(ibm/bea)_15=…

5. If the WebLogic server instance is installed as a Windows Service, it is required to re-install the Windows service. To do so, run the script uninstallService.cmd first and then the script installService.cmd in the WebLogic domain directory

6. Remove the instance directory from the data collector home directory. The path is DC_home/runtime/wlsServer_Version.Domain_Name.Computer_Name.Instance_Name

7. Remove the configuration properties file for the WebLogic server instance

   1. Go to the directory DC_home/installer/_uninst/configured/wls.

   2. For each properties file starting with the name config, for example, config636300264.properties, search for the keyword RUNTIME_DIR=DC_home/runtime/wlsServer_Version.Domain_Name.Computer_Name.Instance_Name.

   3. If the keyword is found, delete the file. Note there should be only one file to be deleted

8. The unconfiguration process is completed. You can start the WebLogic server instance now

data collector for WebLogic server instance cannot be unconfigured after the password of the WebLogic domain administrator is changed

The problem: data collector for WebLogic server instance cannot be unconfigured by the Configuration Tool after the password of the WebLogic domain administrator is changed.

The reason: The Configuration Tool is using the old password to connect to the WebLogic domain administration server, as the password is stored locally in a configuration file by the Configuration Tool.

The solution: Use the password updater program to update the stored password.

To launch the password updater program in GUI mode:

1. From DC_home/itcamdc/bin directory, run the script password_updater.sh (or password_updater.cmd on Windows).
2. On the panel, select the WebLogic instance in which the user name and password need to be updated.

3. Enter the new user name and password.

4. Click the Update button to finish the process.

To launch the password updater program in silent mode:

• From DC_home/itcamdc/bin directory, run the script password_updater.sh (or password_updater.cmd on Windows).

  Syntax:

  password_updater.sh (or password_updater.cmd on Windows) 
  -instance=instance_name -username=user_name 
  -password=password

  ...where:

  instance_name is the name of the WebLogic server instance in the format of wlsserver_version.domain_name.computer_name.instance_name. For example, wls8.fp3test.tiv119.myserver.

  user_name is the new JMX user name

  password is the new JMX password
