Configure the Command Central and Platform Manager JVMs
When you installed Command Central and Platform Manager, a JDK was installed with them. Command Central monitors the JVM for various fault conditions and takes a specified action when a fault occurs, as shown below. Do not change the settings for any of these features unless specifically asked to do so by Software AG.
The following table describes the monitoring features and their default state.
Feature | Default |
Detect a non-operational (hung) JVM. After the JVM starts, Command Central pings it periodically. If the JVM does not respond within a specified interval, Command Central assumes the JVM has stopped functioning and restarts it. | Enabled |
Detect thread deadlocks in the JVM. A thread deadlock occurs when two or more threads try to lock resources in a manner that causes all threads to wait indefinitely. Command Central can monitor the JVM for a deadlock condition and take a specified action (for example, restarting the JVM) when the condition occurs. | Enabled |
Detect specified messages in the console output. Command Central can monitor the console output and take a specified action when a given text string appears. This feature is often used to watch for out-of-memory messages. | Disabled |
Command Central requires a JDK, but Platform Manager can use a JRE. If necessary, you can specify a different JDK or JRE by modifying the wrapper.java.command property in the Command Central and Platform Manager custom_wrapper.conf files in the Software AG_directory/profiles/CC or /SPM directory, respectively. After editing and saving the file, restart the product.
Important: If you specify a different JDK or JRE, do not remove the JDK that Software AG Installer installed with Command Central and Platform Manager. It is required to run the Uninstaller.
You can modify the Java heap size for Command Central and Platform Manager, and you can modify or add JVM options.
1. For Command Central, go to Environments > ALL > Instances > CCE > Configuration. For Platform Manager, go to Environments > ALL > Instances > SPM > Configuration.
2. By default, the initial size of the Java heap for Command Central and Platform Manager is 32MB and the maximum size is 512MB. To modify the heap size, click Memory and then click Edit.
