更新IBM Websphere（WAS）v8的（GC）垃圾收集策略

Question

We have a Java EE application that runs on Websphere (IBM WebSphere Application Server v8.5.5.1)

According to IBM ( http://www.ibm.com/developerworks/websphere/techjournal/1106_bailey/1106_bailey.html ), the default GC policy of WAS v8 is -Xgcpolicy:gencon

I need to change this default to -Xgcpolicy:balanced

I have searched online and here on stackoverflow but haven't found any instruction how I can achieve this.

Any thoughts?

Answer 1

That's just a JVM property. Have you tried setting that JVM argument in the WAS Admin console?

Middleware servers > server-name > Process definition > Java Virtual Machine

And of course do a save/synch and stop/start of the server to pick up the changes.
