Review the JVM heap size
Review the size of the Java Virtual Machine heap and adjust it, if necessary, to avoid out-of-memory errors.
- Log into the WAS console and select...
Servers | Server Type | WebSphere application servers | Connections server | Java and Process Management | Process Definition | Java Virtual Machine
- Review the Maximum heap size.
Installation Manager sets the following default values:
- Small deployment:
Maximum Heap Size: 2506 MB
- Medium deployment: Maximum Heap Size: 2506 MB
- Large deployment:
Each application in a Large deployment, except News and Search, has a default Heap size of 256 MB. The News and Search applications have a default Heap size of 784 MB.
Ensure that we are not allocating more memory than the physical capacity of the system where the JVM is installed.
- Adjust the current values of the heap size up or down to suit the needs of the deployment and the hardware capabilities.
- Click OK and then click Save.
- Repeat these steps for any additional servers in the deployment.
