crashing jrockit while starting WebLogic

with one comment

Just today I spent some time working on a JVM (jrockit) while starting WebLogic with the default script. The enviroment is rather straight forward:

  • Jrockit (jrockit-jdk1.6.0_22-R28.1.1-4.0.1)
  • WebLogic 10.3.4
  • SOA Suite PS3 (

Now whenever I started WebLogic I ran into a rather lengthy core dump, which you can view: here (just rename to .txt). The interesting part of this core dump is this:

Preview of JRockit VE with WLS 10.3.2

with 10 comments

***** UPDATE *****
Oracle has discontinued JRockit Virtual Edition. All information in this post is legacy. There is no use in trying to download the wlsvePackage because it is gone since 2011.
***** UPDATE *****

On Oracle Open World 2009 I was first introduced with JRockit Virtual Introduction. From the beginning on I was excited by the idea of having a VM based on “just” java, the concept seems quiet strong to me. For those of you unknown to the concept of JRockit VE, here’s the press release announcing the product. The product is not new, BEA was already working on it (e.g. see this link) but just today I found a download of JRockit VE with WLS 10.3.2 installed and I decided to have a look.

Currently there’s no documentation (at least I can’t find it), so in time this post will be irrelevant.

***** UPDATE *****

Rob den Braber pointed out to me that Oracle changed the image for JRockit VE. It doesn’t contain a demo domain anymore.

64-bit JRockit and the 11R1 SOA install

leave a comment »

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/
$ /u01/app/install/ofm_soa_11. -jreLoc /u01/app/jrockit

64-bit J-Rockit

with 2 comments

I figured my English is good enough to understand directions given by Oracle, usually I manage quiet okay. Somehow it wasn’t all clear to me that the JRockit download page stated that you needed to go to, login and search for Oracle BEA & Linux x86-64, click on BEA WebLogic Media Pack for Linux x86-64 and then finally find a link to download JRockit R27.5.0 for Java SE 6 for Linux x86-64.  Even more frustrating is to find out that the jrmc download included JRockit so no separate download was needed anyway.
