I then referred to this IBM Technote: -
which directs one to create a jvm.options file, containing the line: -
There are two options for the location of this file - from the Technote: -
This will take effect for all JVMs that do not have a locally defined jvm.options file.
Once I restarted my JVM: -
Launching MyInstance (wlp-1.0.2.cl0220130316-0213/websphere-kernel_1.0.2) on Java HotSpot(TM) 64-Bit Server VM, version 1.7.0_21-b12 (en_US)

I also tested placing the jvm.options file into the server.config.dir location instead: -
and saw the same effect - verbose GC was enabled when I started the server.
Finally, this IBM Technote: -
