    user grid high memory usage

    Spugna
      Hi everybody.

      I have 2 Sun Solaris 10 Servers with (each) 128Gb of memory and 11.2.0.2 Rac Installed
      On the server are running 2 databases. The memory_max_target for boh the instance is
      (total) 8Gb.
      But this is the memory of the user Oracle, so for me it is reasonable that command
      "prstat -a" is showing a total memory for user Oracle about 11g

      I would like to understand why the user grid that is the owner of the ASM and Clusterware
      processes is using about the same size of memory.
      I think that this is a bit too much.

      In our test environment, recently rebooted user grid is using only 500mb of memory.

      Thanks in advance
