    Linux memory settings

    733922
      We installed the suite on a linux server in a managed configuration (AdminServer, soa_server1, bam_server1).

      At first we didnot change the memory settings so all three process ran with memory settings:

      -Xms512m -Xmx1024m -XX:PermSize=128m -XX:MaxPermSize=512m

      With these settings the suite ran OK at first but gradually the performance detoriated.

      Using jconsole I looked at the memory consumption of the processes and the soa_server1 was using up all memory while the AdminServer and bam_server1 had plenty of memory.
      I changed the memory setting specific to the servers:

      AdminServer, bam_server1

      -Xms768m -Xmx768m -XX:PermSize=128m -XX:MaxPermSize=256m

      soa_server1


      -Xms1536m -Xmx1536m -XX:PermSize=128m -XX:MaxPermSize=512m

      The process have been running stable upto now.

      The server:
      OS: oracle enterprise server release 4 update 7
      Cpu: 4*E7340 @ 2.4 Ghz
      Ram: 8 Gb

      Any other experiences with memory settings on linux and/or using a single server setup vs the shared configuration?
