CLM 4.0.0 + WAS 7.0.0.23 + RHEL 6 - Startup Fails
I've recently installed CLM 4.0.0 on an RHEL6 system and when I try to start WAS, the startup fails with:

I can deploy the WAR files, but when I try to start the applications, the WAS instance crashes. Restarts of the WAS instance meet with the above error in the profiles/AppSrv01/logs/server1/native_stderr.log file. One thing I did different -- for the JVM options, I originally added the '-Xgc:preferredHeapBase=0x100000000' command line argument in the WAS console. When I shutdown and restarted WAS to enact the JVM configuration options, however, Java complained that 'preferredHeapBase' is an unknown option and WAS wouldn't start. Here is an example: [root@clmappst02 server1]# /opt/IBM/WebSphere/AppServer/java/jre/bin/java -Xquickstart -Xmn512m -Xgcpolicy:gencon -Xcompressedrefs -Xgc:preferredHeapBase=0x100000000 -Xmx4096 JVMJ9GC040E Unknown option: preferredHeapBase=0x100000000 JVMJ9VM015W Initialization error for library j9gc24(2): Failed to initialize; unable to parse command line Could not create the Java virtual machine. Here is my JVM version info: [root@clmappst02 server1]# /opt/IBM/WebSphere/AppServer/java/jre/bin/java -version java version "1.6.0" Java(TM) SE Runtime Environment (build pxa6460sr2-20080818_01(SR2)) IBM J9 VM (build 2.4, J2RE 1.6.0 IBM J9 2.4 Linux amd64-64 jvmxa6460-20080816_22093 (JIT enabled, AOT enabled) J9VM - 20080816_022093_LHdSMr JIT - r9_20080721_1330ifx2 GC - 20080724_AA) JCL - 20080808_02 Has anyone else run into this, or similar, issues? I've double checked all the RPM pre-requisites for installing WAS. It even runs great without the CLM apps deployed. As soon as they are deployed, however, BOOM, no workie. |

How much memory does your machine have? If you are using the recommendations to start with a 4 gb heap, then you need to have at least 6 or better 8 gb ram on your server. I also do not see the -Xms 4g parameter in your post. The -Xgc:preferredHeapBase option should have worked. Make sure you are adding the jvm params to the correct area in the console. Also, make sure that when you applied the fixpack 23 to WAS that you also applied the corresponding fixpack for the jvm.
Please review the instructions here: http://pic.dhe.ibm.com/infocenter/clmhelp/v4r0/topic/com.ibm.jazz.install.doc/topics/c_admin_was_console.html

Here is the work item that was used to track and settle on the recommended jvm settings for 4.0.
