To modify the Java heap size of AhsayOBM version 5.5, you need to amend the following files:

For Windows:
${OBM-Install-Home}\config.ini
${OBM-Install-Home}\bin\RunOBC.bat

For Linux / Unix / Mac OS X:
${OBM-Install-Home}/config.ini
${OBM-Install-Home}/bin/RunBackupSet.sh

Please open “config.ini”, “RunOBC.bat” or “RunBackupSet.sh” with a text editor and you should see entries as shown below:

config.ini:

app.system.ui.vm.opt.xmx=384
app.system.ui.vm.opt.xms=32
app.system.common.format.datetime.hourinday=true
….


RunOBC.bat:

SET JAVA_HOME=%OBC_HOME%\jvm
SET JAVA_EXE=%JAVA_HOME%\bin\java.exe
SET JAVA_OPTS=-Xms32m -Xmx512m -Dsun.java2d.noddraw
…


RunBackupSet.sh:

LIB_HOME=./bin
JAVA_OPTS=”-Xmx256m -Djava.library.path=$APP_HOME/bin”
CLASSPATH=$LIB_HOME:$LIB_HOME/obm.jar:$LIB_HOME/obm-lib.jar
MAIN_CLASS=RunBackupSet
…


The value 384, 512 and 256 is the current Java heap size which by default is 384MB, 512MB and 256MB


Please amend the line by changing the default value to “768″, (or 1024 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.xmx=768
app.system.ui.vm.opt.xms=32
app.system.common.format.datetime.hourinday=true
…


RunOBC.bat (updated):

SET JAVA_HOME=%OBC_HOME%\jvm
SET JAVA_EXE=%JAVA_HOME%\bin\java.exe
SET JAVA_OPTS=-Xms32m -Xmx768m -Dsun.java2d.noddraw
…


RunBackupSet.sh (updated):

LIB_HOME=./bin
JAVA_OPTS=”-Xmx768m -Djava.library.path=$APP_HOME/bin”
CLASSPATH=$LIB_HOME:$LIB_HOME/obm.jar:$LIB_HOME/obm-lib.jar
MAIN_CLASS=RunBackupSet
…


Once done, please restart the AhsayOBM scheduler service
