Problem with PermGen memory (Java) - Tomcat Server - Business Object XI

Question

We have installed Business Objects XI on a W2003 Standard with SP2 (x86), using Tomcat as web server and MySQL as DBMS. The server has 4 GB of RAM and dual-core processor. From the beginning we have been given the memory problems of the Java virtual machine. The exception that occurs is of type "java.lang.OutOfMemoryError: PermGen space failure". We modify environment variables (JAVA_OPTS) -XX: PermSize = 256m and-XX: MaxPermSize = 512m and install the monitor LambdaProbe to see the use made of memory. We note that at no time was the PermGen memory indicated by these variables, continuing in that has a default 64MB. For this reason we decided to change the Tomcat 5.5 BO included in the version 6.0.20 and also updated Java to version 1.6.0_18-b07, and make deployment by wdeploy.bat file that comes with BusinessObjects (changing config.tomcat55 and tomcat55.xml). The deployment was successful and everything works, but as with the previous version of Java / Tomcat, shortly PermGen memory fills and returns to "hang". In this latest version of Tomcat installed as a service, do not use environment variables, use an application, "Configure Tomcat", which is a tab to pass parameters to the JVM. After looking at many sites, I have seen to be putting "-D" to pass the parameter. Currently this is my configuration:
-Dcatalina.home = C: \ Program Files \ Apache Software Foundation \ Tomcat 6.0-Dcatalina.base = C: \ Program Files \ Apache Software Foundation \ Tomcat 6.0-Djava.endorsed.dirs = C : \ Program Files \ Apache Software Foundation \ Tomcat 6.0 \ endorsed-Djava.io.tmpdir = C: \ Program Files \ Apache Software Foundation \ Tomcat 6.0 \ temp-Djava.util.logging.manager = org.apache.juli . ClassLoaderLogManager-Djava.util.logging.config.file = C: \ Program Files \ Apache Software Foundation \ Tomcat 6.0 \ conf \ logging.properties-Dcom.sun.management.jmxremote-D-Xms2g-D-Xmx2g-D -XX: + UseConcMarkSweepGC-D-XX:-D PermSize = 256m-XX: MaxPermSize = 512m-Daf.configdir = C: / Program Files / Business Objects / Dashboard and Analytics 12.0-D-verbose: gc-D-XX : + PrintGCTimeStamps-D-XX: + PrintGCDetails
I tried changing the values of-XX: PermSize and XX: MaxPermSize, and modifying the various policies of the Garbage Collector (-XX: + UseConcMarkSweepGC,-XX: + UseParNewGC,-XX: + UseParallelGC, ...), but nothing. Any idea how to get change the value of the report? Or how to solve this problem?
Thank you!

Answer 1

Victor,
Is the Product you are using BusinessObjects Enterprise XI (Release 1)?
With XIR2 and XI31, Tomcat 5.0 and Tomcat 5.5 are included with the software, and when installed with the BOE installer, you will get an application installed to the startmenu named "Tomcat Configuration".
Using this "Tomcat Configuration" utility, there are several configuration options available.  On the JAVA tab, you will see the JAVA_OPTS that are set (These are prefixed with "-D") and also your initial and max memory sizes are listed at the bottom (Max 1024 by default in XI31).
Here is the default setting for permsize in XI31 Tomcat:
-XX:MaxPermSize=256M
From your post, your issue might be the spaces in between your values (there should be no spaces, each "-" parameter on its own line).
I would suggest starting Tomcat and reviewing your stdout.log file to review what options were set.
Hope that helps
