Jdk vs. jrockit in WebLogic

We know that jdk is used in development whereas jrockit is used in production. My question is, if any change is made in development then how to make sure it would work in production?
Thanks in advance

Hi,
Please refer to : http://weblogic-wonders.com/weblogic/2010/09/03/why-and-how-oracle-jrockit/
Your statement is not correct.
Questrion:1): We know that jdk is used in development whereas jrockit is used in production. 
Above Statement is Not correct, Because
*1).* JRockit itself is a JDK.
*2).* Many JDKs are available in the Market which can be used anywhere like Production/Development Envs Like -- Oracle Sun JDK, Oracle JRockit JDK, IBM JDK...etc.
*3).* It is true that JRockit is specially designed for Production Environments ...because it has a Best Enhanced Garbage Collection Strategies, It have a JRMC tool inbuilt to Monitor the JVM Activities in the Runtime with very less Burden on the Server/JVM.
There are some More Reasons ...Why JRockit is More Recommended for Production Environments
- It Has More diagnostic tools than other JDKs such as JRA
- Management console with no overhead on performance (JRMC)...which is available inside <JROCKIT_HOME>\bin directory.
- Better performance on Intel architectures than other JVMs
- Higher memory usage for better performance
Questrion:2): If any Changes made in Development Mode ....then U might have tested it properly in the Development Mode ...If everything Looks good then only we move to the Production with those Changes. That's what all the Admins and Companies do. They implement some features in Development Env then Test it ...If the Test Succeeds all the perspectives ....then only we Move that Environment to the production.

Need steps for JDK to JRockit

Hi All,
Currently we are using JDK1.7.0.21 for weblogic 10.3.6 , SOA 11.1.1.6 and AIA in Production(Linux64bit). new i want migrat to Oracle JRockitJDK.can any body sent some steps for that and some documents plz..
Thank you,
Ram.

There is a small example here: Middleware Snippets: WebLogic, Coherence and the G1 Collector
Note that this goes the other way around, from JRockit to Oracle JDK. In your case you can set the JAVA_VENDOR to Oracle (instead of Sun) and enter the BEA_JAVA_HOME value.
There is something like the following in the setDomainEnv file (located in the ${DOMAIN_HOME}/bin directory):
WL_HOME="/home/weblogic/weblogic12.1.1/installation/wlserver_12.1"
export WL_HOME
BEA_JAVA_HOME="/home/weblogic/jrockit-jdk1.6.0_29-R28.2.2-4.1.0"
export BEA_JAVA_HOME
SUN_JAVA_HOME="/home/weblogic/jdk1.7.0_11"
export SUN_JAVA_HOME
JAVA_VENDOR="Sun"
export JAVA_VENDOR
if [ "${JAVA_VENDOR}" = "Oracle" ] ; then
JAVA_HOME="${BEA_JAVA_HOME}"
export JAVA_HOME
else
if [ "${JAVA_VENDOR}" = "Sun" ] ; then
JAVA_HOME="${SUN_JAVA_HOME}"
export JAVA_HOME
else
JAVA_VENDOR="Oracle"
export JAVA_VENDOR
JAVA_HOME="/home/weblogic/jrockit-jdk1.6.0_29-R28.2.2-4.1.0"
export JAVA_HOME
fi
fi
By changing the JAVA_VENDOR to the right one, you can see the in the 'if' statement JAVA_HOME is set by using either SUN_JAVA_HOME or BEA_JAVA_HOME
The nodemanager.properties also has properties where JAVA_HOME is set (javaHome and JavaHome).

How do I use jdk 1.4 with weblogic 6.1?

Want to use jdk 1.4 features(logging and regular expression) in a weblogic
 application I am developing. How do I get weblogic 6.1 to run with jdk1.4


 This is off topic but see the url below on edocs.
 You will need to make sure that your classpath points to the 1.4 jdk. Changing
 your $JAVA_HOME in the startup script is pretty much it.
 When developing your application, make sure your classpath is set properly .For
 example in the setExamplesSever.sh script you point to the 1.4 jdk.
 FYI This is not yet a supported platform.

Support for JRockit for WebLogic 10.3 in Solaris x86

Hi All,
I am trying to install JRockit Mission Control 3.1.2 in a Solaris 10 x86 platform.
For Solaris Spark I know there is a special distribution.. For Solaris 10 x86 I am trying to install the generic linux version.
When I try to install the jrmc-3.1.2-1.6.0-linux-ia32.bin I get the following error:
jrmc-3.1.2-1.6.0: Cannot find /lib/ld-linux.so.2
I also try with 64bit edition of the jrockit mission Control but I get a similar error but trying to find the /lib64/ld-linux.so.2.
Is Solaris 10 x86 supported? Or at least, is there a workaround to install it?
I find some site talking about JRockit for Solaris Spark, but seems to me that Solaris x86 is not supported...
Thanks in advance
Pablo

Hi,
The DTD used in "web.xml" should not cause any issue ...though it's the OLD "web.xml"...Please try to run the Following command to Generate the New Deployment Descriptors from the Existing Application:
Step1). Open a Command Window and Run "setWLSEnv.sh" or "setWLSEnv.cmd".
Step2). In the Command Prompt move to the Current Directory where you have placed your Application and then Run the Following Command
java weblogic.DDConverter -d NewDDs jamagent.war
Here Above Command Will read the "jamagent.war" War archive and then It will generate the New DDs in "NewDDs" directory...Which we need to replace with the OLD DDs present in our WebApplication..
Thanks

Uninstall SUN JDK 1.6_14 and install SUN JDK 1.6_18 for Weblogic

My GridControl server has all of a sudden gone wild in consuming 100% of the cpu. The process was java.exe in the Middleware folder. Somebody suggested to verify the JDK and I indeed have an older version than the one recommended.
Does anybody know where it is documented on how to uninstall and then reinstall SUN JDK 1.6_18 and have Weblogic still work afterward? (Win 2008 32 bit)
I'd hate to reinstall the entire Gridcontrol 11g because I have the wrong jdk.
Thanks.

Hi,
Uninstalling SUN JDK 1.6_14 from your Box is optional step....Most of the Servers are flexible enough ...they provide us the facility to change the JDK at any point of time...Without reinstalling the Product from the scrap....
You can directly install SUN JDK 1.6_18 in your WebLogic Server Box. Then you need to make a small change in the *"<DOMAIN_HOME>\bin\setDomainEnv.cmd"* file ...to change the JAVA_HOME variable value...That's all.
Next time whenever you will start your WebLogic Servers it will pick up the SUN JDK 1.6_18 version only.
I am pasting few lines from *"setDomainEnv.cmd"*
@REM *************************************************************************
set WL_HOME=C:\bea103\wlserver_10.3

Unable to start weblogic with JRockit

i am using a 32 bit machine to start weblogic server on JRockit JVM. Doing this in order to have already installed Oracle SOA suite and when I start weblogic using JRockit it is Running out of memory. Tried the solutions given in the forum but not able to resolve this issue.
Also when using jdk getting permgen error. Tried with resetting the maxPermSize value etc in the startweblogic server but not able to do so.
For JRockit OOM has any one faced a similar issue?
Can any one help me with same ?

Thanks Carlos. The value was getting overridden in startweblogic.cmd for Sun jdk but was not sufficient for my problem as I was using Jrockit and with JRockit there is no Permsize issue inturn there was OOM.
I followed these steps:
1. changed maxpermsize in startweblogic.
2. Tried increasing system swap space.
3. Used a profiler which controls JVM running, tried reduce memory leaks, but none worked.
I switched to JRockit for weblogic
1. tried increasing memory etc. Finally I switched to 64 bit machine as suggested in one of the forums for JRockit oom.
Now both jdk and JRockit weblogic with all SOA components working successfully.
Thanks,
Dipti Karnataki

Weblogic 9.0 on WinXP 64bit with Sun JDK 64bit

I installed Weblogic 9.0 on WindowXP 64bit version and it's fine with build in Sun's JDK and JRockit JDK but as soon as I switch to Sun's 64bit implementation of JDK (update 5) it fails to start.
Am I doing something wrong or it is not compatible with 64bit JDK on windows platform?
If so are there any plans to make it compatible with Sun's JDK 64bit version on windows platform in the near future, or any chance of 64bit JRockit JDK for windows?

JRockit 8.1 for Weblogic server 7.0

Hi,
Try to know if I can install JRockit for weblogic application server 7.0.
Any suggestions?
Thanks

Hi,
WLS 70 hasn't been certified with any JDK 1.4 VMs. JRockit 8.1 comes only as
JDK 1.4 compatible. So, you cannot use this with WLS 70.
You can use JRockit 70SP2 with WLS 70SPx.

How to start managed server on Weblogic 9.1 Admin console with jRockit

Weblogic and Jrockit

Hi All,
Please help me with the following query.
Environment
BI 4.1 SP02 FP03
OS :- Windows 2008
Application Server :- Weblogic 11 (installed on Windows) using Jrockit
Issue
We are in the process of deploying war files on Weblogic. I have set the jvm_is_jrockit=true in config.weblogic11. But when I execute the "wedeploy weblogic11 predeployall" I get the following message.
"does_weblogic_use_jrockit:
refine_file_layout_for_jrockit is false"
Everything works fine on the weblogic end. Is this an issue or am I missing out any configuration which needs to be done for using jrockit with weblogic?
Regards
Chinmaya

I was able to figure this out. For using jrockit as jvm we need change "jvm_is_jrockit=true" found in <Install Dir>\SAP BusinessObjects Enterprise XI 4.0\wdeploy\conf\weblogic11.conf"
1. You will see "refine_file_layout_for_jrockit is false" for all applications except dswsbobje.
2. It will generate a ear file for BOE application. (Note :- It creates a war file if jrockit parameter is set to false).
Thanks
Chinmaya

Is Oracle Weblogic server 10.3 compatible with jdk 1.5.0?

When i point 1.5.0 JDK version to Oracle Weblogic server 10.3 "Bad version number in .class file" error is thrown while starting the server.
can any one help me to resolve this issue?
Edited by: user10643892 on Nov 23, 2008 10:40 PM

Hi, there.
You are right. The overview page has no clear statement on JDK. However, if you look into the supported operating system links, you'll find only JDK 6 is supported. Example for Solaris:
http://edocs.bea.com/platform/suppconfigs/configs/solaris/solaris10_103.html
Note that there is support for JDK 5 clients, which may be useful to you:
http://e-docs.bea.com/wls/docs103/notes/new.html#wp1090981
I hope this answers your question.
Cheers,

Which BEA WLS version (+ service packs) used which JDK/JRockit-JDK version

Hello,
I'm looking for an overview about the JDK and JRockit JDK versions which are used in the different BEA WLS versions.
Specialy im interested on all BEA WLS server versions (incl. the different Service Packs) starting with version 7.0.
The overview should contain the following information if possible:
- BEA WLS Version Number including SP
- Plattform (Windows, HPUX, Solaris, ...)
- JDK version
- JRockit JDK version
Here is an example (??? = I do not know currently):
WLS vers. (incl. SP)|Plattf.|JDK vers.|JRockit vers.
7.0.1 |Solaris|??? |???
8.1.5 |Windows|1.4.2_08 |rockit81sp5_142_08
9.2 MP1 |HPUX |??? |???
Thanks a million if somebody could provide me those information. :-x

Weblogic 10, JRockit 1.5, Xverbose:exceptions=trace

When I start my instance of Weblogic with the -Xverbose:exceptions=trace option, the log gets to over 1GB before the Weblogic instance is even finished starting up. I looked at the logs and most of the exception stack traces are coming from JRockit or Weblogic themselves - not the code I'm trying to run.
Is there a way to filter the output from -Xverbose:exceptions - like with a log4j.properties type file or some such? I looked around and haven't been able to find any information on this. Again, we're talking Weblogic 10.1 and jrockit-jdk1.5.0_15_32

Does Weblogic 8.1 support JDK 1.5

Dear All,
I tried to use JDK 1.5 with weblogic 8.1 but I couldn't. Can I do this. When I change the JAVA_HOME to be JDK 1.5 I got the following error while weblogic tries to initialize:
The WebLogic Server did not start up properly.

Anyone can help...

Your crash could be solved by the fix for [6579892|http://bugs.sun.com/view_bug.do?bug_id=6579892], which is reported as being in progress.
Also of interest is [6372116|http://bugs.sun.com/view_bug.do?bug_id=6372116], which would certainly make your problem go away. Unfortunately, this was fixed in 5.0 and brought forward, but not backported to 1.4.2, so it doesn't help you. You could add a comment and vote for this one to raise the awareness of the issue.
