As part of the App Visibility agent for Java installation process, you must add the agent JVM options to the Java command line of your application server.

The procedure to update the JVM options is different for each application server type, and this topic provides examples for some of the leading types of application servers. If you have more than one JVM process using the same agent installation, assign meaningful names to distinguish each instance.

This topic includes the following sections:

Before you begin

  • Install an App Visibility agent for Java
  • The App Visibility agent for Java requires up to 256 MB of JVM heap memory. When the agent runs in the same JVM memory space as the monitored applications, BMC recommends adding 256 MB to the Max heapsize Java options flag -Xmx.

    Example

    set JAVA_OPTS=%JAVA_OPTS% -Xmx1024m

    For full details about both the -javaagent and Xmx options, refer to the Java options documentation for your application server type.

  • In the following procedures, replace the <AgentInstallationDirectory> with the location where the agent is installed. The default folder is the one from which the installation script is run, for example:
    • Windows
      <AgentInstallationDirectory>\ADOPsInstall\adops-agent.jar
      Where <AgentInstallationDirectory> is the C:\bmc\appvis_agent directory

    • Linux
      <AgentInstallationDirectory>/ADOPsInstall/adops-agent.jar
      Where <AgentInstallationDirectory> is the /usr/bmc/appvis_agent directory

To distinguish multiple JVM processes using the same agent installation

If you have a single App Visibility agent installation directory that is used by multiple JVM processes, you can assign meaningful names to distinguish each instance. Otherwise, the same application server name (defined during installation) might be displayed multiple times.

Use one of the following command-line arguments for each JVM process:

  • -Dcom.bmc.adops.agent.instance.global.name=<globallyUniqueName>
    The <globallyUniqueName> value must be unique among all App Visibility agents in the system.
  • -Dcom.bmc.adops.agent.instance.local.name=<locallyUniqueName>
    The <locallyUniqueName> value must be unique for each application server instance on the computer that uses the agent. The <locallyUniqueName> value is appended to the application server display name defined during agent installation (or the agent host name, if you did not define a name during installation).

Note

The values for <globallyUniqueName> and <locallyUniqueName> can include only alphanumeric Latin characters, spaces, underscore characters (_), and hyphens (-).

You should configure WebSphere JVM options from the admin console; configuration should not be done from the start script.

  1. Log in to the WebSphere admin console.
  2. Expand Server Type and select WebSphere application servers.
  3. Click the name of the server to which you would like to attach the App Visibility agent.
  4. Expand Java and Process Management and select Process Definition.
  5. Under the Additional Properties section, click Java Virtual Machine.
  6. Scroll down and locate the text box for Generic JVM arguments.
  7. Add the following lines: 

    • Windows

      -javaagent:<AgentInstallationDirectory>\ADOPsInstall\adops-agent.jar -Dcom.bmc.adops.agent.instance.local.name=<locallyUniqueName>
    • Linux

      -javaagent:<AgentInstallationDirectory>/ADOPsInstall/adops-agent.jar -Dcom.bmc.adops.agent.instance.local.name=<locallyUniqueName>
  8. Save the configuration.
  9. Restart the WebSphere Application Server process.
    For further information about setting JVM arguments in WebSphere, see the IBM website .

To update options for Oracle WebLogic

  1. Edit the startWebLogic script.
    The file extension is cmd (Windows) or sh (Linux).
    This script is used when starting both admin and managed servers. The startManagedWebLogic script calls the startWebLogic script.
  2. Locate the JAVA_OPTIONS environment variable and add the following lines:

    • Windows

      set JAVA_OPTIONS=%JAVA_OPTIONS% -javaagent:<AgentInstallationDirectory>\ADOPsInstall\adops-agent.jar -Dcom.bmc.adops.agent.instance.local.name=<locallyUniqueName>
    • Linux

      JAVA_OPTIONS="${JAVA_OPTIONS} -javaagent:<AgentInstallationDirectory>/ADOPsInstall/adops-agent.jar -Dcom.bmc.adops.agent.instance.local.name=<LocalUniqueID>"
  3. Restart the WebLogic Application Server process.
    For further information about specifying Java options for a WebLogic server instance, see the Oracle website .

To update options for Apache Tomcat

  1. Edit Tomcat’s catalina script.
    The file extension is bat (Windows) or sh (Linux).
  2. Locate the CATALINA_OPTS environment variable.
  3. Add the following lines:

    • Windows

      set CATALINA_OPTS=%CATALINA_OPTS% -javaagent:<AgentInstallationDirectory>\ADOPsInstall\adops-agent.jar -Dcom.bmc.adops.agent.instance.local.name=<locallyUniqueName>
    • Linux

      CATALINA_OPTS="-javaagent:<AgentInstallationDirectory>/ADOPsInstall/adops-agent.jar -Dcom.bmc.adops.agent.instance.local.name=<locallyUniqueName>"
  4. Restart the Apache Tomcat Application Server process.
    For further information about changing Java options when Tomcat runs as a Windows Service, see the Apache website .

To update options for JBoss

  1. Edit the JBoss run script.
    The file extension is cmd (Windows) or sh(Linux).
  2. Locate the JAVA_OPTS environment variable.
  3. Add the following lines:

    • Windows

      set JAVA_OPTS=%JAVA_OPTS% -javaagent:<AgentInstallationDirectory>\ADOPsInstall\adops-agent.jar -Dcom.bmc.adops.agent.instance.local.name=<locallyUniqueName>
    • Linux

      JAVA_OPTS="$JAVA_OPTS -Djava.net.preferIPv4Stack=true -javaagent:<AgentInstallationDirectory>/ADOPsInstall/adops-agent.jar -Dcom.bmc.adops.agent.instance.local.name=<locallyUniqueName>"
  4. Restart the JBoss Application Server process.
    For further information about updating both the JBoss run.conf file and run script, see the JBoss website .
