We have an Oracle RAC production environment with primary and secondary DB. Our DBA has asked to update oracle version from 11.2.0.1.0(64 bit) to 11.2.0.3(64 bit) with patch 6880880,10404530,16803769 and 16803775.
In our current database we have Shared storage,ACL settings, security settings,Gateway/Heteregenous connectivity, Dataguard, Data broker, Backup policy and Oracle Client installed on other machines.
DBA has estimated that he need to do installation, settings from scratch and test.. So, when the version is updated, do we really need to reconfig and install everything (Shared storage,ACL settings, security settings,Gateway/Heteregenous connectivity, Dataguard, Data broker, Backup policy and Oracle Client installed on other machines) ?? If yes its fine, but no then I need to justify it.
I can understand testing would be required..
