# 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.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.pentaho.com/install/9.3-install/pentaho-configuration/tasks-to-be-performed-by-a-pentaho-administrator/configure-the-design-tools-and-utilities/pdi-design-tools-and-utilities/increase-the-pdi-client-memory-limit/modify-the-pdi-client-startup-script.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
