Node Manager can start a server without requiring you to specify startup options. However, if you have modified your environment; for example, if you have added classes to the WebLogic Server classpath, you must specify startup options before you use the Administration Console to start a server.

There are two ways to add JVM arguments on WebLogic.

1- Without Nodemanager ( startManagedWebLogic.sh — java options)
2- With Nodemanager ( Weblogic Console -> Server Start-> Arguments)

You can compare JVM Arguments of managed servers using with WL-OPC.

  1. Compare and analyze JVM runtime and startup arguments
  2. Find missing or different JVM runtime or startup arguments easily then align all your JVM arguments

How can we compare server arguments in WL-OPC? Let’s take a look step by step with screenshots:

1- Go to “Tools & Utils > Compare JVMs” in WL-OPC Menu

2- Select Domain and Server then click `Compare Startup Argument` or `Compare Runtime Arguments`

3- Matched or missmatched of two separate JVM arguments.

Additionally, we have prepared screen cast tutorial about JVM server arguments.
