Configure JVM Log Files

One of the first things an administrator should do when Connections has been installed is change the size of the JVM log files. The SystemOut and SystemErr log files are used to trouble shoot the system and it’s a good snap shot of how each server and application is running.

By default when WebSphere is installed the size is set to 1mb, which fills up and rolls over very quickly on a busy system. No historical logs are kept by default making it very difficult to trouble shoot errors.

It is a sensible option to change the log size to between 20 – 40mb and keep at least 5 historical log files. This allows a good amount of log collection for trouble shooting, to send to IBM If a PMR is required etc.

The file size and history must be configured on each of the servers including the deployment manager and node agents.
