    Recommended Memory Usage

    Chris Shen Newbie

      We are in the process of upgrading from 4.0.4 to eap 4.3. I was reading the datasheet for eap 4.3, and it suggests 512mb ram as a minimum system requirement. I was wondering if this refers to half a gig of overall actual memory on the physical server or the amount of process space available to the app server.

      Also, on the wiki, I have come across this formula to calculate process space: TotalProcessSpace = .5GB(java overhead) + Heap + (Threads*ThreadStackSize)

      http://www.jboss.org/community/docs/DOC-11564

      Is it suggesting that the overhead for jvm operations may take up half a gig of ram outside of the heap and stack memory allocated?

      Thanks in advance.
