I wonder if it might be better to have a KARAF_OPTS environment variable
just like there is a CATALINA_OPTS one for the below memory settings for
Tomcat. That would have the benefit of allowing the user to specify
default memory values for Karaf specifically without needing to set them
at the JVM level (affecting everything else) in order for karaf.bat to
pick them up--same benefit Tomcat users have with CATALINA_OPTS.
Definition of CATALINA_OPTS (in catalina.bat):
rem CATALINA_OPTS (Optional) Java runtime options used when the "start",
rem "run" or "debug" command is executed.
rem Include here and not in JAVA_OPTS all options,
that should
rem only be used by Tomcat itself, not by the stop
process,
rem the version command etc.
rem Examples are heap size, GC logging, JMX ports etc.
How it's implemented:
%_EXECJAVA% %JAVA_OPTS% %CATALINA_OPTS% %DEBUG_OPTS%
-Djava.endorsed.dirs="%JAVA_ENDORSED_DIRS%" -classpath "%CLASSPATH%"
-Dcatalina.base="%CATALINA_BASE%" -Dcatalina.home="%CATALINA_HOME%"
-Djava.io.tmpdir="%CATALINA_TMPDIR%" %MAINCLASS% %CMD_LINE_ARGS% %ACTION%
goto end
Regards,
Glen
