64-bit JRockit and the 11R1 SOA install

Somehow I keep on running into trouble installing 64-bit Oracle Fusion Middleware SOA suite. The process seems quiet simple if you follow the installation guide. First of all I installed the 64-bit J-Rockit (see this post how to download it).

$ export JAVA_HOME=/u01/app/jrockit
$ export PATH=$JAVA_HOME/bin:$PATH
$ java -version
java version “1.6.0_03”
Java(TM) SE Runtime Environment (build 1.6.0_03-b05)
BEA JRockit(R) (build R27.5.0-110_o-99226-1.6.0_03-20080528-1505-linux-x86_64, compiled mode)

Next I started the generic installer and installed the weblogic server:

$ java -jar /u01/app/install/wls1032_generic.jar

Then it is time to set the environment and start the installer:

source /u01/app/oracle/middleware/wlserver_10.3/server/bin/setWLSEnv.sh
$ /u01/app/install/ofm_soa_11.1.1.2.0/Disk1/runInstaller -jreLoc /u01/app/jrockit

BPEL dehydration store and HW contention

Today I spent some time on fixing performance issues with the BPEL dehydration store. The database is a three (3) node RAC cluster, running RBDMS 10.2.0.4 on ASM 11.1.0.7. BPEL connects to a service name that has one (1) preferred instance and two (2) available instances.

HW contention usually means: trouble with lobs. Just to be sure, I started to check metalink. First of all I discovered I had to set event 44951 to fix bug 6376915 (setting an event without restarting the database means setting events =, next set the event in the spfile). This didn’t clear my HW contention problems though.  What did solve the problems, was moving the lobsegments to a separate tablespace. Here’s the script I used to move the lobsegments (with some extra segment space shrinking):
