Environment

Release : 9.3+

Component : Applications Manager Client

Resolution

The default memory allocation of 256MB can be increased by editing the client.properties file located in the same directory as the RunClient.jar.

1. Edit the client.properties file with a text editor
2. Edit the line "#runOptions=-Xmx256m", remove the # and change the memory value
3. For example, if you want 1024 MB of Java memory, the value will be set to "runOptions=-Xmx1024m"
4. Save the file and restart the Client if it is open to register the changes.
