Documentum on AIX

We run Documentum on AIX. Under stress the application performed not well. Looking more deeply into the Java, we saw a lot of garbage collection and waits. The default garbage collection on AIX is OPTTHRUPUT. This is not the best for applications such as Documentum with only quick objects. The default is good for batch operations, so large objects and more time.

So we change to the more appropriate GENCON and it went smoother, less GC and less waits. But now we have to look at the application because some code is still not performing, but I leave that to the Java/Documentum guys.
