Qshell environment variables

WebSphere Application Server provides these Qshell environment variables that affect the WebSphere Application Server scripts:

To set these variables, run this command:

  export variableName=value

To unset these variables, run this command:

  unset variableName

• WAS_ADDL_JVM_ARGS
  If you set this variable, its value is appended to the Java virtual machine (JVM) arguments for all of the scripts that run a JVM. (All of the scripts except crtwasinst, dltwasinst, updwashost, enbprfwas, startServer, startNode, startManager, lstwasinst, grtwasaut, and rvkwasaut run a JVM.) For example, this command:

  export WAS_ADDL_JVM_ARGS="-Dtrace=com.ibm.*=all=enabled -Xms256m"

  enables tracing for the JVM that a script starts, and sets the minimum heap size for the JVM to 256 megabytes.

• WAS_USER_SCRIPT
  This variable specifies the path to a script that runs before a WebSphere Application Server Qshell script runs. For example, if you want to append a /home/QSYS/classes.jar to the classpath for every script, you might create a script called /home/myDir/classpath.script. The script file contains this command:

  WAS_CLASSPATH=${WAS_CLASSPATH}:/home/QSYS/classes.jar

  After you create the script file, run this command to set the environment variable:

  export WAS_USER_SCRIPT=/home/myDir/classpath.script
