JBOSS TAKES EXTREMELY LONG TIME TO START ON AIX(24 minutes)!

sdj Nov 13, 2005 6:33 AM

Hi ,

I have an urgent problem where recently we have been running JBOSS 3.2.5. on AIX 5.2 (takes about 30 seconds to start).

We have recently moved the same system to a newly setup box AIX 5.3. elsewhere and it takes about 24 minutes!! to start up JBoss and then each of the later processes using JBOSS also takes a significant longer amount of time. If run on windows, again it is fast.

We have been looking into the problem, has anyone ever seen this problem before? Any suggestions? Anything to look for?

This seems to be similar to the post of jdebruin 'JBOSS ON AIX VERY SLOW' on November 9th.

I would be grateful for any input on the subject as this preventing us from appropriately running the application.

Thank you.

whoa...that is an old version of JBoss. I have never seen 3.x on AIX at all so I cannot speak to anything there. The AIX JVMs are very bad and I bet you'll have issues with other Java apps if you are finding it this slow. I'm betting you have an equally antiquated AIX JVM. Jboss 4.x runs as good as can be expected (again the AIX JVMs are not good) on AIX 5.2 with a recent 1.4.2x JVM (haven't seen it on the JDK 5.0 vms) in comparable time to other platforms.. However I'm betting you have a VM or AIX patches problem.

I had a problem with jboss taking ages to start and it was due to the internal hypersonic database growing extremely large.

I think jboss is loading it into memory when it starts.

I use jms on my server but after the message has been processed, i dont need to keep it.

My hypersonic db was 1.25 Gig. Anyway, i replaced the files in /server/default/data/hypersonic with a fresh copy.

This fixed my startup problems, from 20+ minutes to 30 seconds - like a fresh install.

Thanks
Dave

All caps for emphasis :-)

DO NOT USE HYPERSONIC IN PRODUCTION. REMOVE HYPERSONIC.

Yes hypersonic runs its whole log again on starturp.

We include hypersonic for a test/dev database.
