GC statistics/info

[nabieh]

Dears,
When the GC performs its processes, it has been all logged some where, do you know how can I get the GC or DGC process logs in order to know when those processes ran and how long is the gap between one and another. Thanks in advance.

You will have to add the java option -Xloggc:filename to the run.bat. Something like:

set JAVA_OPTS=%JAVA_OPTS% -Xms128m -Xmx512m -Dsun.rmi.dgc.client.gcInterval=3600000 -Dsun.rmi.dgc.server.gcInterval=3600000 -Xloggc:D:/log/myLogFile.log

You will then see the GC logs in D:/log/myLogFile.log file

Along with the -Xloggc:filename you might also want to add
-XX:+PrintGCDetails to get the details of GC.

set JAVA_OPTS=%JAVA_OPTS% -Xms128m -Xmx512m -Dsun.rmi.dgc.client.gcInterval=3600000 -Dsun.rmi.dgc.server.gcInterval=3600000 -Xloggc:D:/log/myLogFile.log -XX:+PrintGCDetails
