Manually removing data collector configuration from an application server instance

To manually remove the data collector configuration from an application server instance, you must be able to connect to the application server by using the wsadmin tool. This is possible only if you are using WebSphere® Application Server Network Deployment and the Deployment Manager is running. If the WebSphere application server cannot start, you must restore the WebSphere application server from the backup taken when you run the configuration utility.

To manually remove the data collector configuration, complete the following procedure:

1. Log in to the WebSphere Administration Server Console.
2. Click Servers.
3. Expand Server Type and select WebSphere application servers.
4. Click the name of the server.
5. In the Configuration tab, go to Server Infrastructure > Java and Process Management > Process Definition > Java Virtual Machine > Additional Properties: Custom Properties.
6. Remove any of the following JVM Custom Properties, if they are present:
   • am.home
   • ITCAM.DC.ENABLED
   • TEMAGCCollector.gclog.path
   • com.ibm.tivoli.itcam.toolkit.ai.runtimebuilder.enable.rebuild
   • com.ibm.tivoli.jiti.injector.ProbeInjectorManagerChain. primaryInjectorFile
7. Identify the JVM arguments that were added for the data collector.
   1. In the navigation pane, click Environment > WebSphere Variables.
   2. If you manually configured the application server for data collection, locate the JVM arguments you added manually.
      If you configured the application server for data collection with the configuration utilities, compare the values of the AM_OLD_ARGS and AM_CONFIG_JVM_ARGS arguments to determine which arguments were added by the configuration utility.
8. Click Server > Application Server and select the appropriate server name.
9. In the Configuration tab, go to Server Infrastructure > Java and Process Management > Process Definition > Java Virtual Machine.
10. In Generic JVM Arguments field, remove the JVM arguments that you identified in Step 7 for the data collector.
11. Click Apply or OK.
12. In the Messages dialog box, click Save.
13. In the Save to Master Configuration dialog box, complete one of the following steps:
    • If you are under a Network Deployment environment, make sure that the Synchronize changes with Nodes check box is selected, and then click Save.
    • If you are not under a Network Deployment environment, click Save.
14. Remove environment entries that were added for the data collector.
    1. In the Configuration tab, go to Server Infrastructure > Java and Process Management > Process Definition > Environment Entries.
    2. Depending on the operating system, delete the following environment entry:
       • LIBPATH
       • LD_LIBRARY_PATH
       • PATH
    3. Remove the NLSPATH environment entry.
15. Click Apply or OK.
16. In the Messages dialog box, click Save.
17. In the Save to Master Configuration dialog box, complete one of the following steps:
    • If you are under a Network Deployment environment, make sure the check box Synchronize changes with Nodes is selected, and then click Save.
    • If you are not under a Network Deployment environment, click Save.
18. In the navigation pane, click Environment > WebSphere Variables.
19. Delete the following variables:
    • AM_CONFIG_JVM_ARGS
    • AM_OLD_JVM_ARGS
    • ITCAMDCHOME
    • ITCAMDCVERSION
20. In the Messages dialog box, click Save.
21. In the Save to Master Configuration dialog box, complete one of the following steps:
    • If you are under a Network Deployment environment, make sure the check box Synchronize changes with Nodes is selected, and then click Save.
    • If you are not under a Network Deployment environment, click Save.
22. If you configured the server instance for data collection with the data collector configuration tool, rather than manually, complete the following steps:
    1. Navigate to the dc_home/runtime directory.
    2. Rename the $profile.$cell.$node.$server.input.properties file to $profile.$cell.$node.$server.input.properties.bak.
23. If you are manually removing the data collector configuration from all application server instances in a profile, perform the following steps:
    1. Navigate to the $appserverhome/bin directory.
    2. Run the osgiCfgInit.sh/bat -all command on Windows systems or the osgiCfgInit.sh -all command on UNIX and Linux® systems.
24. Restart the application server instance that was monitored by the data collector.
