We are having an oracle database version 188.8.131.52 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 184.108.40.206.
can anybody provide me the steps how to migrate oracle database from windows(32 bit) to Solaris10(64 bit) and then upgrade it to 220.127.116.11.
