Modify the PDI client startup script

1. Exit from the PDI client if it is currently running.

2. Open the PDI client startup script with a text editor. The name of startup script depends on your operating system.

   • Windows Name and Location of Startup Script: pentaho/design-tools/data-integration/Spoon.bat

   • Linux Name and Location of Startup Script: pentaho/design-tools/data-integration/Spoon.sh

3. Modify the -Xmx value so that it specifies a larger upper memory limit.

   In this example, 2g (two gigabytes) of heap space has been allocated.

   PENTAHO_DI_JAVA_OPTIONS="-Xmx2g -XX:MaxPermSize=256m"

4. Save and close the startup file.

5. Start the PDI client and ensure that there are no memory-related errors.

   If you see an error, repeat these steps to increase the memory again.

PDI client now has higher memory limits.

You need to increase the Pentaho Server memory limit as well.
