2. Re: Specifying Heap Size & JVM Memory for JBoss Instance / Node !!
peterj Apr 29, 2010 11:36 AM (in response to saswatamandal)Why not make copies of run.bat, one for each instance, and set the heap sizes in those copies?

So, If i change the HEAP SETTINGS of the file for node 1, save it to the bin directory by the name runnode1.bat , and in the command prompt type :-
runnode1 - c node1 -b IP ADDRESS -g CLUSTER NAME
, will that solve my requirement ??
Is that a GOOD IDEA to do that ??
Because I thought , there must be some way to pass the HEAP VALUES at runtime by the run -D option for the nodes !!!
OR , to specify the HEAP VALUES in a configuration file for the specific nodes !!
Thanks & Regards
Saswata Mandal.

peterj Apr 29, 2010 12:33 PM (in response to saswatamandal)1 of 1 people found this helpfulPlease don't use bold text, it looks as if you are shouting.
You cannot set the heap sizes using -D options.
Your plane on creating runnode1.bat and editing the heap settings in there is a good one. I would go even further and hard-code the "- c node1 -b IP ADDRESS -g CLUSTER NAME" within runnode1.bat - you could add it to this line:
"%JAVA%" %JAVA_OPTS% "-Djava.endorsed.dirs=%JBOSS_ENDORSED_DIRS%" -classpath "%JBOSS_CLASSPATH%" org.jboss.Main - c node1 -b IP ADDRESS -g CLUSTER NAME %*

saswatamandal Apr 29, 2010 12:36 PM (in response to saswatamandal)Isn't there any way to pass the HEAP VALUES at runtime by the run -D option while starting server instances ??

saswatamandal Apr 29, 2010 12:41 PM (in response to saswatamandal)Hi,
Can we create our own properties and use the C:\jboss-4.2.0.GA\server\node1\deploy\properties-service.xml file utilize them ??

peterj Apr 29, 2010 12:42 PM (in response to saswatamandal)I asked you to not use bold text, so now you are using bold and blue. Does that mean you are yelling at me? I usually do not respond when I get yelled at.
Go and read the JVM documentation regarding the use of the -D option (since you did not believe my original aswer to your question).

saswatamandal Apr 29, 2010 12:52 PM (in response to saswatamandal)Hi Peter,
You actually read my mind .
I was about to ask you , how can we include the :- run -c node1 -b ipaddr -g clustername , in the runnode1.bat.
Your suggestions are really helpful , I shall implement them as you have suggested and shall get back to you soon.
Thanks & Regards

praveen.kumar Jun 11, 2010 5:18 AM (in response to saswatamandal)Hi Mandal,
Do like this,create two jboss instance say,
/opt/jboss1 and /opt/jboss2 so that your node1 in jboss1 and node2 in jboss2.Finally makeJVM settings in their respective run.bat.
No need to use bold or colored letter .
Enjoy..

11. Re: Specifying Heap Size & JVM Memory for JBoss Instance / Node !!
saswatamandal Jun 18, 2010 9:10 AM (in response to praveen.kumar)I liked , Peter's idea of copying the run.bat file in the bin directory , renaming them for different nodes , and modified jvm settings for the specific nodes.
That way , we shall have multiple nodes with different jvm settings in the same JBOSS Server.
I am going to implement it today , and shall update the post.
Thanks & Regards
saswata mandal.

Your suggestion, has worked fine .
I am able to run the nodes with different JVM configurations.

babulreddy Feb 8, 2013 11:25 AM (in response to saswatamandal)Hi All,
I have a doubt on Jboss memory allotment
I have 5 cluster nodes in JBOSS1
I want to give 5 different memory settings for all nodes
Cluster1 - 2048
Cluster2 - 1024
Cluster3 - 3.5 GB
Cluster4 - 4GB
Please can I know how can we set the memory setting for each cluster node.
Thanks
Babul
