Migration suggestion if multiple Exadata Compute Node Oracle Homes are using mixed lower versions than the shared Grid Oracle Home
Last updated on JANUARY 23, 2013
Applies to:Oracle Exadata Hardware - Version 126.96.36.199 and later
Information in this document applies to any platform.
You intend on using a single Exadata box with database for TEST / UAT and a PROD database
This means that compute nodes may have more than one RDBMS version: Older for PROD and the newer targeted version for UAT/TEST
This may be testing for different patchset levels
eg. 188.8.131.52.4 vs. 184.108.40.206.8
e.g. 220.127.116.11 vs. 18.104.22.168)
Your concern is : How do I test patching the GI / Infra at different levels if we are using a single-shared storage which means a single ASM and GI version
In this case the user accidentally created multiple RDBMS patched versions at different patchset levels for multiple RDBMS homes while only using a single Grid Infrastructure for the storage cell nodes.
That is: now we have several database levels but only one ASM / GI level shared by all of the RDBMS versions
