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.
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, modify or add JVM options, and modify Java system properties.
