BusinessObjects BI 4.0 Installation and java memory consumption

[Former Member]

Hi all,

I'm working with an installation of BusinessObjects BI 4.0 on a machine Windows 2008 Server 64bit and in these last day I noticed a serious performance problem. Server is very slow, and I see from task manager the process java.exe that occupied a lot of resources. CPU usage grows till 95-99 and come back to 0 periodically. In the past weeks this problem didn't occur.

Did somebody have this problem in the past? what could be the cause?

Thanks for the support!

Hi,

Goto Tomcat Properties --Java Tab and enter the parameters like below

-XX:PermSize=256m

-XX:MaxPermSize=256m

-XX:NewSize=171m

-XX:MaxNewSize=171m

-XX:SurvivorRatio=2

-XX:TargetSurvivorRatio=90

-XX:+DisableExplicitGC

-XX:+UseTLAB

Restart the Tomcat and SIA's and check again.

Hello Arjun,

are this properties also valid for Linux? What's about -Xmx1024m?

Thanks and best regards,

Max

-XmX1024M that's what I set in my system.

Check this note which has the parameters

1346684 - "java.lang.OutOfMemoryError: Java heap space" in Tomcat Web Application Server (doesn't say WIn or Linux)

This note for Linux - 1637342 - Tomcat hangs or crashes: Exception in thread "CompilerThread1" java.lang.OutOfMemoryError
