I apologize if this is a duplicate, but I can’t seem to find this answered anywhere.
What is the best way to increase the maximum Java heap size when using Apache Karaf?
Currently, I modified the following line in the karaf.bat file:
set DEFAULT_JAVA_OPTS=-server -Xmx<NewMaxValue>M.
I feel like modifying the bat file is not the best solution. Additionally, none of the config files seem to have a place to put this.
Updating to Karaf 2.2.3 reveals a new bat file.
if "%JAVA_MIN_MEM%" == "" ( set JAVA_MIN_MEM=128M ) if "%JAVA_MAX_MEM%" == "" ( set JAVA_MAX_MEM=512M ) if "%JAVA_PERM_MEM%" == "" ( set JAVA_PERM_MEM=16M ) if "%JAVA_MAX_PERM_MEM%" == "" ( set JAVA_MAX_PERM_MEM=64M )
This means one can just create a system variable instead of modifying the bat file.
