| Does anyone know if we should have Garbage Collection running for an iSeries install of WebSphere 5.0.2? I'm assuming that iSeries does a lot of the memory management, and we've been told that by IBM that Garbage Collection isnt needed on iSeries, but, quite frankly, I dont believe them... |

If you don't believe 'em than I guess go ahead and run the garbage collection, assuming to run or not to run is the only question.  |

The JVM does the garbage collection not the iseries.
The important parameters are initial heap size (mem grabbed from pool at startup) and max heap size (max heap size to use, again grabbed from pool).
The latest version of the OS (v5r3 I think) supports a 32bit JVM which is more efficient than the existing 64 bit JVM if you don't need a massive heap. |
