where to set the JAVA_OPTS for Max memory allocated

[gan.gary]

where's the best place to configure the max memory allocated for JBoss?
In the "C:\jboss-4.2.2.GA\bin\run.bat",

set JAVA_OPTS=%JAVA_OPTS% -Xms128m -Xmx1G

or

environment variable?

Diff?

The run.bat is the right place to do this.

Thanks. why ? Any difference?

I advice you to create a new file of start.

@echo on
rem -------------------------------------------------------------------------
rem JBoss Start CC
rem -------------------------------------------------------------------------

set JAVA_HOME="C:\Progra~1\Java\jdk1.5.0_15"


cd C:\jboss-4.0.5.GA\bin
C:\jboss-4.0.5.GA\bin\run.bat -c default

Those parameters are passed to the JVM. The run.bat (or the run.sh) is responsible for instantiating the JVM. These scripts do not look into the environment variables for JVM options. So you either have to change those scripts yourself to pick the values from environment variables or just (the easier and better way) is to set it directly in the run.bat.

The other reason why i don't set such parameters as environment variables is, these parameters are per JVM and need not be per user or per system. So it makes sense to have them set in the script which instantiates the JVM. Infact, i don't even set the JAVA_HOME as an environment variable, given that i have more than one java installation on my system.

It is not rigth to modify the file run.bat
If you have to set JAVA_HOME, it is better to edit run.conf.
NOTE:
It seems it does not work in WINDOWS :(

So i advice you to create a new file of start.

@echo on
rem -------------------------------------------------------------------------
rem JBoss Start CC
rem -------------------------------------------------------------------------

set JAVA_HOME="C:\Progra~1\Java\jdk1.5.0_15"


cd C:\jboss-4.0.5.GA\bin
C:\jboss-4.0.5.GA\bin\run.bat -c default

erasmarciano, the run.conf file is not used on Windows, so editing it does no good. In addition, gan.gary wanted to know how to set JVM heap options - your example script file does not do this and thus does not solve gan.gary's problem.

Thanks erasmomarciano, jaikiran, PeterJ. I think i gotta modify the "run.bat" anyway, because I need to run the JBoss as windows service, "service.bat" which in turn will call "run.bat" thru':

:cmdStart
REM Executed on service start
del .r.lock 2>&1 | findstr /C:"being used" > nul
if not errorlevel 1 (
 echo Could not continue. Locking file already in use.
 goto cmdEnd
)
echo Y > .r.lock
jbosssvc.exe -p 1 "Starting %SVCDISP%" > run.log
call run.bat < .r.lock -b 0.0.0.0 >> run.log 2>&1
jbosssvc.exe -p 1 "Shutdown %SVCDISP% service" >> run.log
del .r.lock
goto cmd
End

Hi erasmomarciano

It is not rigth to modify the file run.bat

Just curious what make you think we cannot modify it? ANy idea?

Is there any unanswered question here?

[gan.gary]

Hi jaikiran, thanks. I want more input from more people. :)
Because I found most of the threads I posted are either answered by you or PeterJ. I have a feel of thinking that this forum is only 3 of us :(

[peterj]

I won't speak for jaikiran, but as for me, I have no life, which is why I am always in the forums. ;-)

[gan.gary]

I assume JBoss has a small user-base?

[noelo]

You assume wrong.....This is just a section of the forums.

[gan.gary]

but I think this section( almost one third) has the most posts?
