This document (http://documents.bmc.com/supportu/documents/90/37/199037/199037.pdf) is extremely valuable when configuring the Mid Tier, both in regards of memory allocation and cache behavior.
Also I recommend that you try out Tomcat 7.x series, since it has significantly improved memory behavior then the 6.x series ################### ** :) On Thu, Dec 15, 2011 at 9:15 AM, Chowdhury, Tauf <[email protected]> wrote: ** Thereâs also some garbage collection parameters you can add to the java console: -XX:PermSize=256m -XX:+UseCompressedOops -XX:+UseParallelGC From: Action Request System discussion list(ARSList) [mailto:[email protected]] On Behalf Of Rick Sharp Sent: Thursday, December 15, 2011 9:56 AM To: [email protected] Subject: ARS Tomcat Slowdowns are Crippling Us......HELP ! ** Hi All We have a new ARS 7.604 instance with incredible slow MidTier performance every 3 days. Tomcat sucks up 3GB+ RAM and 53% CPU (today) and cripples the MidTier. Restart Tomcat and all is fine for 2 days. Unacceptable to our 200 IT users and is killing us. Our base of 4800 end users touches Remedy via our Kinetic front end, which is never an issue; just the MidTier for IT Staff. Any help is much appreciated !!!! Specifics: We are running Tomcat for ARS and Tomcat for Kinetic, as separate services. The ARS Tomcat runs away with Memory and cripples us at 3GB, while CPU is fine with its service. Kinetic's Tomcat is fine.
