we are preparing our new consolidated database environment (6 databases). It is 2 node 11G R2 RAC on Oracle Linux 6 64bit virtualized on Oracle VM.
Currently we are running split/mixed cofiguration 2 node 10.2.0.2 RAC on HP-UX and 2 node applications on RHEL 4.
We want to migrate the database to 188.8.131.52 RAC using export/import.
The problem is: Oracle Linux 6 is not certified as database operating system for 184.108.40.206 release ...
Oracle Linux end of support is 2017Q1 for OEL5 and 2021Q1 for OEL6.
Upgrage from 11i to R12 should take place in 2013, OEL6 is certified as database OS for R12.
What are your opinions?
Build OEL6 or OEL5 database environment ...
The only thing that can cause problems is running autoconfig scripts on database tier.
But you cannot upgrade OEL5 to OEL6 without reinstall.
It takes some resources ( time and money) to migrate all the databases (wa have 6 production RAC databases). When we use OEL6 in virtual environment we do not need to migrate or reinstall until 2021Q1.
When we use OEL5, at 2017Q1 we need to reinstall OS ( and database software) and migrate all databases ( and reconfigure all applications) to be supported.
I've raised SR with question certified vs. supported, in case of negative answer the only way seems to be the OEL5 way.
Thank you and Regards
