Ayusman,
I have a OS X server, running Tomcat 5.0.19. There are already
three applications running but I will need one more application
which is memory intensive. I wanted to know how can I specify/
increase the memroy requirements for my application or Tomcat
application? My new application may need RAM data of around 800MB
- 1.5 GB; given the condition that the OS X Server Hard Ware is
capable of providing this amount of memory, how do I claim it at
Tomcat startup, so that my application goes smoothly.
Additionally is there any known issues in Tomcat while dealing with
memory intensive applications?
Any inputs will be really helpful.
We use Tomcat 5.5.7 on a Mac Quad Server (4 gigs RAM). Our default
settings are:
-Xms200m -Xmx200m -XX:+MaxFDLimit -server -Djava.awt.headless=true
These work fine except when there are a very large number of
application pages. In this case we use:
-Xms1048m -Xmx1048m -XX:+MaxFDLimit -server -Djava.awt.headless=true -
XX:MaxPermSize=256m
At this point in time, you cannot allocate more than 1 gig to the
heap regardless of whether the machine itself has more RAM.
Initially we thought this would be a hindrance, however experience
has shown us that this limitation has minimal impact.
