These instructions apply when you have installed Pentaho using the installation wizard (as opposed to custom installation), your computer can display graphics, and you are a Linux user.

Perform the following steps to increase the Java VM memory allocation for Linux so that you can automatically start the Pentaho Server:

  1. Stop the appropriate server.
  2. Change the directory to pentaho-server/tomcat/scripts.
  3. Edit the ctl.sh file.
  4. Locate the line under start tomcat, which looks like the following code: 
    export JAVA OPTS="-Dpentaho.installed.licenses.file=/opt/pentaho/.installedLicenses.xml -Xms128m Xmx768m -XX-MaxPermSize=256m -Dsun.rmi.dyc.client.gcInterval=3600000 -Dsun.rmi.dgc.server.gcInterval=3600000"
  5. Set the memory to a minimum of 4096 M and a maximum of 6144 M, depending on your computer's memory capabilities.
  6. Start the server.
    Your server now has increased minimum and maximum memory limits.
You can adjust the JvmMx number (a parameter that specifies the maximum memory limit for the Java virtual machine) to a higher number, if you prefer. However, a problem occurs when there is not enough contiguous memory available to assign to the Java virtual machine (JVM). If the JVM refuses to start with increased limits, then you will have to add more RAM to your system, stop some memory-intensive services, or lower the maximum memory limit allocation.
