Setting generic JVM arguments in WebSphere Application Server

The generic JVM arguments are used to configure and adjust how the JVM executes. Once changes are made and saved to the master configuration, the JVM requires a restart for the arguments to take effect.

NOTE: Setting JVM arguments on the WebSphere Application Server 8.5 Liberty profile has different steps.

• WebSphere Application Server 7.0
• WebSphere Application Server 6.1

How to Append JVM Arguments

Each JVM argument is separated by a space. This is also called it's delimiter.

For example, if presented with these two JVM arguments to add to an already full list of arguments:
-Xrs
-Xint

You would apply each argument individually, separating each with a space.

[other arguments] -Xrs -Xint [other arguments]
