We had the same problem when starting JBoss and then starting the apps that run in/on JBoss. Once it got through the startup "phase" things settled down and ran ok. We just thought it was the nature of the beast. Steve
-----Original Message----- From: Linux on 390 Port [mailto:linux-...@vm.marist.edu] On Behalf Of Ron Wells Sent: Wednesday, February 03, 2010 10:32 AM To: LINUX-390@VM.MARIST.EDU Subject: z/VM; zLinux; SuSE SLES10; JAVA/64Bit; WAS 7.0 FP5; Slow Initialization of WAS with High CPU on IFL The subject pretty much says it all. When we startup/initialize WAS Version 7 the IFL goes to max CPU, the elapsed time for WAS initialization is 5 minutes to 8 minutes. This is just during WAS initialization. The application that are being built and run there appear to work fine in the environment. The concern is the impact to startup/initialization of WAS (test/development/QA) environments on the production WAS as we have single IFL and VM LPAR. Believe we may be able to mitigate the impact of WAS (T/D/QA) through favoring the productions environments. Wanted to see what others might suggest to look into to "tune" the initialization impact. Have heard that WAS 7 may be experiencing this where as WAS 6 this may not have been so prominent SuSE has the Novell delivered JAVA 64B 1.5 SR10 and WAS 7 uses the IBM delivered version of JAVA 64B 1.6 SR5. It may pay to focus on the WAS & JAVA 1.6 environments.
