open the run.sh file ( linux script ) , look first lines JAVA_OPT set the same variables in run.bat file

How among of memory do you got on that server, put here your cpu, disk, OS version etc... do you have more apps installed there ?

Hi

As per your advice I changed the run.bat file to

from

rem JVM memory allocation pool parameters. Modify as appropriate.
set JAVA_OPTS=%JAVA_OPTS% -Xms128m -Xmx512m

to

rem JVM memory allocation pool parameters. Modify as appropriate.
set JAVA_OPTS=%JAVA_OPTS% -Xms512m -Xmx1024m

after changing if click the run.bat i'm getting error as show in screen-shot

i have
Microsoft windows server 2003
Enterprise edition
Service pack 2

Computer :
Intel Core 2 duo cpu
E7500 @ 2.93 Ghz
3.9 GB RAM

Hard disk :
only C drive with total size 74.2 GB with free space of 43.9 GB space

Could any advice how to resolve this ?

Try with it:

Code: Select all

set JAVA_OPTS="-Xms256m -Xmx1024m -XX:PermSize=64m -XX:MaxPermSize=128m -Djava.awt.headless=true"

Seems this older computer with few memory. Next release will have tomcat support and the actual jboss memory need will not be necessary.

Hi jillort ..

I'm just curious to know how you are setting the value for JAVA_OPTS ? does it depends on CPU configuration ? If so my configuration is
Intel Core 2 duo cpu
E7500 @ 2.93 Ghz
3.9 GB RAM..
For the above configuration , what is the optimum value for JAVA_OPTS ?

When will the next release will come with that TOMCAT support ?

Depends of your available memory in this case you could increase to -Xmx2048m, 2GB used by application server and other 2GB for OS

Hi jllort,

Do you know how to install and configure jRockit as JVM and point to JAVA_HOME variable to the JVM path ?

I read the forum http://forum.openkm.com/viewtopic.php?f=4&t=3908 .
But i'm not able to proceed how to configure this tool after downloading it . do you have any idea ? If so can you help me ?

I've never installed jRockit as JVM you should use java jdk 1.6 is version what we've tested and we can ensure all goes fine.
