Eclipse Installer only: Customizing heap settings

If your organization chooses to install TPF Toolkit by using the Eclipse Installer, you can customize the heap settings of the Java™ virtual machine (JVM) for TPF Toolkit by adding Eclipse.ini tasks to your TPF Toolkit product catalog (com.ibm.tpf.toolkit.products.setup). Eclipse.ini tasks are used to set parameters in the Toolkit.ini file.

About this task

For each JVM setting that you want to change, add one Eclipse.ini task, for example:
  • To set the minimum heap size, create an Eclipse.ini task, and add the –Xms parameter with a value that you want specified.
  • To set the maximum heap size, create an Eclipse.ini task, and add the –Xmx parameter with a value that you want specified.

This procedure sets the maximum heap size to 2024 MB for illustration.

Procedure

Follow the procedure in Eclipse Installer only: Customizing TPF Toolkit startup, and in step 4, specify the fields in the Properties window as follows:
  1. In the ID field, specify a unique ID for the Eclipse.ini task.
  2. Optional: In the Description field, enter a description about the Eclipse.ini task.
  3. In the Option field, enter –Xmx.
  4. In the Value field, enter a value to indicate the maximum heap size, for example, 2024 MB.
  5. In the VM field, set the value to true.

Results

The next time your users start TPF Toolkit, the –Xmx value that you specified will automatically be added to the TPFToolkit.ini file in their TPF Toolkit installation directory, and TPF Toolkit will be running with the heap setting applied.
