How do I modify the Java heap size of DotnetOBM or DotnetACB?

How to modify the Java heap size of DotnetACB version 5.5.x / 6.x

How to modify the Java heap size of DotnetOBM version 5.5.x / 6.x

Instruction for DotnetACB version 5.5.x / 6.x:

To modify the Java heap size of DotnetACB version 5.5.x / 6.x, you need to amend the following files:

For Windows:

${DotnetACB-Install-Home}\config.ini

${DotnetACB-Install-Home}\bin\RunOBC.bat

For Mac OS X:

${DotnetACB-Install-Home}/config.ini

${DotnetACB-Install-Home}/bin/RunOBC.sh

Please open "config.ini" and "RunOBC.bat" with a text editor and you should see entries as shown below:

config.ini:

app.system.ui.vm.opt.xms=32

app.system.ui.vm.opt.xmx=384

app.system.conf.language

RunOBC.bat:

...

SET JAVA_HOME=%OBC_HOME%\jvm

SET JAVA_EXE=%JAVA_HOME%\bin\java.exe

SET JAVA_OPTS=-Xms32m -Xmx512m -Dsun.java2d.noddraw

...

The value 384 and 512 is the current Java heap size which by default is 384MB and 512MB

Please amend the line by changing the default value to "768", (or 1028 depending on the amount of free system memory available) so the line will appear similar to the example as follows:

config.ini (Updated):

app.system.ui.vm.opt.xms=32

app.system.ui.vm.opt.xmx=768

app.system.conf.language

RunOBC.bat (Updated):

...

SET JAVA_HOME=%DotnetOBM_HOME%\jvm

SET JAVA_EXE=%DotnetOBM_HOME%\jvm\bin\java.exe

SET JAVA_OPTS=-Xms32m -Xmx768m -Dsun.java2d.noddraw

...

Once done, please restart the DotnetACB scheduler service
