We are having an oracle database version 184.108.40.206 and running on windows 2003 (32 bit). When some load increase in the database its performance slow down, using /3g we have increase the SGA+PGA memory to 2.5 G still we are facing the problem. Currently the database size around 70Gb. As because no oracle version matches with our existing infra, so we have decided to migrate to solaris10 (64 bit) in oracle version 220.127.116.11.
can anybody provide me the steps how to migrate oracle database from windows(32 bit) to Solaris10(64 bit) and then upgrade it to 18.104.22.168.
