Wie Ändere ich den Java-Heap-Größe der Software?

Betriebsystem

All platforms

Software

5.x - 6.x

Fehler Meldung

java.lang.OutOfMemoryError: Java heap space

Ursache

The software reached the maximum allowed amount of RAM memory resulting in the above error.

Lösung

! Newer software might have different values or be more effecient with it's RAM usage.
To modify the Java heap size of 5.5.x / 6.x, you need to amend the following files:

For Windows:

• ${Install-Home}\config.ini
• ${Install-Home}\bin\RunOBC.bat
• ${Install-Home}\bin\RunBackupSet.bat

For Linux / Unix / Mac OS X:

• ${Install-Home}/config.ini
• ${Install-Home}/bin/RunOBC.sh
• ${Install-Home}/bin/ RunBackupSet.sh

Please open "config.ini", "RunOBC.bat" or "RunBackupSet.bat" with a text editor and you should see entries as shown below:
(The current values in the example may differ per software version)

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 …

 

RunBackupSet.bat:

… 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.xms=32 app.system.ui.vm.opt.xmx=768 app.system.conf.language

 

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.bat  (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 Online Backup Scheduler service.
