Increase the Pentaho Server memory limit

We recommend that you increase PDI's memory limit so the Pentaho Server and the PDI client (also known as the design tool Spoon) can perform memory-intensive tasks, like sorting, grouping large datasets, or running complex transformations and jobs. You will need to increase the memory limit for both the Pentaho Server and the PDI client. If you choose to not increase the memory limit, PDI uses the default memory settings in the PDI startup scripts.

The way that you increase the memory settings for the Pentaho Server depends on your operating system and how you installed PDI:

• Increase Pentaho Server memory limit for installations on Windows

• Increase Pentaho Server memory limit for installations on Linux

• Increase Pentaho Server memory limit for custom installations on Windows or Linux
