memory issues on Oracle 11g Database

Dear All,

We have Oracle Database Enterprise Edition 11g Release 11.1.0.7.0 64-bit on Microsoft Windows 2008 64-bit with two nodes Oracle RAC.  We are having some out of memory issues when we run some applications and some times instances crash due to outr of memory.  The Database Server is having 32-GB of RAM.  This was installed by earlier DBA.  When I investigated I saw following:

*.memory_target=2133852160 rac1.memory_target=1073741824 rac2.memory_target=2147483648 and rac11.memory_max_target=3221225472 rac2.memory_max_target=3221225472 What I have done I removed  rac1.memory_target=1073741824 and  rac2.memory_target=2147483648 as this shows both instances having different memory target.  I kept *.memory_target=2133852160 and increased memory_max_target to 4GB.  System seems okay for now.  Can any one further suggest on this? If we increase memory_max_target to 6GB or 8 GB would this be helpful or peformance issues might be created? ._spin_count is set to 2000.  Is this okay also? Thanks

Howdy, Stranger!
