-X flags that influence GC's on HP Java 1.4

[Doug High_1]

Hi. On AIX, there is a flag called -Xgcpolicy:optavgpause that enables the concurrent for GC's. I'm looking for a similar flag for HP's JDK. I am working with a node pool (group of multiple JVM's that are typipcally 128mb to 1024mb in size). I'm noticing that when they do a full GC...that the STW is definitely hitting the resources on my HP SuperDome. Does HP have an equivalent flag similar to IBM's -Xgcpolicy:optavgpause

Thank you!!!!

You could use -Xincgc for similar effects on the length of garbage collection pauses. There is a long document on the applicable garbage collection options at
