Setting Java heap size

The Java Virtual Machine requires enough heap memory to prevent out-of-memory conditions.

If Java heap memory is set too low, TestArchitect may not have enough memory to perform normal operations. Set the Java heap size at a level that is large enough to enable TestArchitect to function properly, but not so large that the amount of physical memory available to other applications is affected. The table below lists the minimum, recommended, and default Java heap size settings for 64-bit systems.

Machine ArchitectureRecommended Heap SizeMinimum Heap SizeDefault Heap Size
64-bitHalf of total physical memory512 MBHalf of total physical memory

The current Java heap size setting is displayed in the Repository Server Information panel in the Repository Server Control Panel window.

  1. Open the Repository Server Control Panel dialog box.

  2. On the toolbar, click Options…

    The Options dialog box appears.

  3. In the Set Heap Size panel, type the amount of memory (in megabytes) that is to be made available to Java as heap storage, and then click OK.

    Click Reset dialog box to return the heap size to the default setting for your system.

Changing the Java heap size value automatically restarts the repository server. All access to the server is temporarily disabled while the server restarts. Server requests made during this time will be rerouted to a replication server, if one is available.
