-jrockit option

Hi.
What' s the meaning of "-jrockit" start-up option?
(ex. java -jrockit -xmx128m -xms128m ... )
I couldn't find the note about it in any guides or something like that...

The "-jrockit" start-up option only makes explicit that you want to run the
"jrockit" VM, but since that is the only VM alternative for the JRockit
JRE/JDK
it is actually redundant and have no effect.
You can see information about it's use by running 'java -help' which prints
$ java -help
---<---
where options include:
-jrockit to select the "jrockit" VM
The default VM is jrockit.

Unable to bypass jrockit option

HI Gentlemen,
I have downloaded a good sample Applet/ADF program. It has been working A1 with my Java7 and JDeveloper 11.1.1.0.6. After installing Java and Fusion Middleware several times, now trying to execute the .jspx page with the builtin weblogic server always generates a java command with -jrockit, which is not available. I am completely blocked from further development. Can anyone help me, why it now complains about jrockit, which I do not use at all?
Thank you, kind regards:

VolanoMark is slow over 8 users - JRockit 5.0SP1/Linux ia32

Hello,
Using the VolanoMark benchmark
http://www.volano.com/benchmarks.html
works fine up to 8 users per room (3% CPU idle)
$ java ... COM.volano.Mark -rooms 1 -users 8
but over 8 users, sometime abruptly slows down
(> 90% CPU idle) as if a timeout had been introduced.
Instrumenting the code, it appears that a wait()
that takes usually less that 1 ms, takes now 38 ms.
(in COM.volano.t)
On ia32/Linux, only with JRockit 5.0 (OK with 1.4.2)
# dual Intel PentiumIII
Red Hat Enterprise Linux AS release 3 (Taroon Update 4)
Linux 2.4.21-27.ELsmp
glibc-2.3.2-95.30
java version "1.5.0_02"
Did someone else observe such a behavior ?
Some JRockit options to solve that problem ?
Thanks
Denis

Hi Denis!
You can email the JRA recordings to [email protected] and refer to this thread in the forum.
Thanks,
/Helena
I've collected data for JRA before and after the slowdown
(users=8/9) - the same proportion of Fat locks in
COM.volano.ae (subclass of COM.volano.t calling wait()) ...
but divided by 20 ...
How can I post these files to you ?
Thanks,
Denis

Hi,
Tanks for response !
But, -XX:+PrintConcurrentLocks does not work with JRockit.
Is this default JRockit option, as noticed in the article ?

Note that you are using the HotSpot JDK. The option -jrockit is only valid if you are using JRockit.
When you open setDomainEnv.cmd you see something like:
if "%JAVA_VENDOR%"=="Oracle" (
     set JAVA_HOME=%BEA_JAVA_HOME%
) else (
     if "%JAVA_VENDOR%"=="Sun" (
          set JAVA_HOME=%SUN_JAVA_HOME%
     ) else (
          set JAVA_VENDOR=Oracle
          set JAVA_HOME=C:\bea\jrockit_160_29_D1.2.0-10
)which selects a certain JDK based on the set JAVA_VENDOR property.
You add the property JAVA_VENDOR above the first if statement, for example,
set SUN_JAVA_HOME=
set JAVA_VENDOR=Sun
if "%JAVA_VENDOR%"=="Oracle" (...)Also see if the SUN_JAVA_HOME property is set to the correct directory.

Steps to enable "-Xmanagement" option in JRockit JVM?

Hello,
I am trying to enable the "-Xmanagement" option in the Jrockit JVM 1.4.2_04 to enable the management server to listen to the JVM running on our server. Therefore, we can use the JRA to profile our JVM in realtime, using the JRockit Management console.
We are running W2K3 and use the registry to pass all the necessary options (i.e. -classpath, verbose:gc, min/max heap size, -D options etc.) when starting the Weblogic service. However, when I attempt to add the -Xmanagement option to anywhere in the registry setting, the service will fail to start, regardless of where I place the option in the field.
If I cannot set this option, I recieve the below error when attempting to connect to the server via the management console ( I have tried various ports as well )

Hi Helena,
Below are the values from the registry key we are passing to the weblogic service.
We do not use any of the "Start(WLS)(Weblogic).cmd" scripts to start the Weblogic service, only the WSM (Windows Service Manager).
Please let me know if you have any further questions.
Thanks for the assitance.

I am able to boot the app server by changing in the configuration file -->setENV.cmd.
I put -server instead of -jrockit, i don't know why it is pointing to -jrockit.
Below is the value that I put -->
SET JAVA_OPTIONS_WIN=-server -Xms256m -Xmx256m -XX:CompileThreshold=8000 -XX:MaxPermSize=128m
in place of below value-->
SET JAVA_OPTIONS_WIN=-jrockit -XnoOpt -XXnoJITInline -Xms512m -Xmx512m -Dtoplink.xml.platform=oracle.toplink.platform.xml.jaxp.JAXPPlatform
I am still not able to check the status of the server and shut it down properly.
Any suggestions ?

Configuring Domains to Use the Latest Version of JRockit
If you are using the JRockit SDK, after you install an upgrade patch or run an Upgrade installer, Oracle recommends that you upgrade your domains to use the latest production version of the JRockit SDK. Although the latest version of the JRockit SDK is installed by the upgrade patch or upgrade installer, your domains are not automatically configured to use it.
To configure your domains to use the latest production version of the JRockit SDK, edit the following file:
For Windows:
MW_HOME\domain_location\domains\domain_name\bin\setDomainEnv.cmd
For UNIX:
MW_HOME/domain_location/domains/domain_name/bin/setDomainEnv.sh
Replace all occurrences of the existing JRockit version with the latest production version of the JRockit SDK.
For example, if you are upgrading from WebLogic Server 10.3.2 to WebLogic Server 10.3.3, replace
jrockit_160_14_R27.6.5-32
with
jrockit_160_20_D1.0.1-2119
You can determine the JRockit SDK version number to use for your WebLogic Server version by looking at the JRockit directory name in MW_HOME. The number to use is identical to the directory name.

Hi All,
After the upgrade of jdk 1.6.20 to 1.6.35 version, getting unrecognized option jrockit error while starting the admin server.
Please help me on this.
Thanks,
Varaprasad

Have you altered in any way your startWebLogic.sh, commEnv.sh (either one) or setDomainEnv.sh scripts? We had issues with customizations previously made that prevented the scripts from auto-detecting the JVM and choosing appropriate flags.
Another option is to forcefully set JAVA_VENDOR=Sun and export JAVA_VENDOR at the start of your startWebLogic.sh or setDomainEnv.sh scripts, to override the automatic JVM settings. You may then need to additionally set memory settings however.

Unrecognized option: -jrockit (weblogic)

after the jdk upgrade 1.6.20 to 1.6.35 version while starting the admin server getting unrecognized option: -jrockit.
Please help me on this.

Ok, it seems that you have used Hot Spot JDK, instead of Jrockit. Please make sure that you have downloaded the correct package for Jrockit.

How to run a JRockit process in the background(Linux ia64)

Hello,
I am trying to start a JRockit process 1.4.2 (with a Java app) from an SSH console and make it keep running after I log out. This is on Redhat Enterprise Linux WS 4 with Itanium II processor (ia64).
The obvious thing such as
java <options> <class> &
or even
nohup java <options> <class> &
Do not work and the process terminates when I log out.
Is there a recommended method or a facility to run JRockit in the background as a service/daemon? Does JRockit has switch similar to â€“Xrs of Sunâ€™s JVM?
Starting the process on system boot and having to reboot the system to restart it are not acceptable.
Any help will be greatly appreciated.
Thanks,
Zapta

Zapta did get an answer. You may have missed it if you're using nntp to access the forums, since many newsreaders don't track threads that change the subject. I recommende the using the web UI at dev2dev.bea.com.
Anyway - Use "-Xnohup" with older versions of JRockit. In recent JRockit versions, "-Xrs" works as well, since we seen problems with people hardcoding that flag into various applications launchers (Tomcat for one).
Cheers!

JBoss EAP 6 On JRockit - Memory Leak

hello team.
I have memory leak problem on jboss and jrockit.
My Environment :
1. OS :
CentOS release 6.4 (Final)
2. JRockit :
java version "1.6.0_45"
     Java(TM) SE Runtime Environment (build 1.6.0_45-b06)
     Oracle JRockit(R) (build R28.2.7-7-155314-1.6.0_45-20130329-0641-linux-x86_64, compiled mode)
3. Application Server:
JBoss EAP 6.2.0.GA
4. Application
Large EJB Application (100 and more EJB Beans (Stateless, Stateful, MDB, Timers and so on)
Everything works fine on older application server versions (4.3 , 4.2)
But now I have Problem
Of course I know that problem is new version - and i have discussion on JBoss forums.
but guys I have question about jrockit with you:
What is the option "Other" in memory ??

Not sure what the 'other' is, but it is probably best shown by using an example. By using displayMap we can display a memory map of various JVM subsystems and libraries that are loaded, including third-party libraries.

Here
- thread is thread related (such as thread stacks)
- int, internal use (such as pointer pages)
- heap, chunk used by JRockit for the Java heap
- os, mapped directly from the operating system, such as third party DLLs or shared objects
- msp, memory space. a memory space is a native heap with a specific purpose, for example native memory allocation inside the JVM
- gc, garbage collection related, for example live bits
- code, compiled code
The 'other' memory space looks to me (from the blank entries in the above print-out) like they are a memory pages to are still not used. When the JVM starts it mappes an amount of memory. To my knowledge JRockit uses mmap (mmap(2) - Linux manual page), which creates a new mapping in the virtual address space. JRockit reserves an amount of memory (Java Heap (heap where your object instances go) + its own runtime (all the others)).
To see where the growth is in the various memory spaces, you can use 'print_memusage baseline', after which you can execute print_memusage again, for example,
./jrcmd 4523 print_memusage scale=M
4523:
Total mapped                     3896MB      +4MB (reserved=2905MB -3MB)
-              Java heap          512MB           (reserved=0MB)

-                     OS          143MB
-                  Other         2043MB
-            Classblocks            7MB           (malloced=7MB #20596 +532)
-        Java class data          126MB      +4MB (malloced=125MB +4MB #93640 +2592 in 20596 classes)
- Native memory tracking            1MB           (malloced=0MB #20 +10)
Note the additional column that prints out the difference in memory usage in relation to the baseline. You can also monitor native allocations by using trace_alloc_sites, memory allocations can then be displayed with different levels of detail using the level argument.
./jrcmd 4523 print_memusage trace_alloc_sites=true

Note this is more on the JVM level, in your case in might be beneficial to investigate what is happening on the java heap. By using print_object_summary you can get insight how memory on the heap is used on a per-class basis. To get to the bottom of where the memory leak is you can use the memory-leak-detector (an example of its use can be found here Middleware Snippets: Fast, Faster, JRockit). You can also obtain a heapdump that can be analyzed by using for example MAT (see for an example here Middleware Snippets: Visualizing Class Loading). To obtain a heapdump you can run the command, for example,
[weblogic@machine1 bin]$ ./jrcmd 4523 runsystemgc full=true fullcompact=true
4523:
[weblogic@machine1 bin]$ ./jrcmd 4523 hprofdump filename=/home/weblogic/dump.hprof
4523:
Wrote dump to /home/weblogic/dump.hprof
Note that this first issues a full GC by using the runsystemgc command.

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