JAVA JVMs like real storage :-)
The Garbage Collection (GC) runs periodically and references ALL JVM

Good afternoon all,
Just wondering if anyone has some input (good, bad, warnings ...) or
has had to used the following two items we are running VM5.4 and

Hi Paul ,
The drop_caches is a command itself . To have it working you should create a
cron job to issue the command all the time what is not so good .
