Re: Question about changing GI Home

I was able to prove the process for moving a Grid Infrastructure home to a new location. Moved GI from /u01/app/grid/11.2.0.4 to /u01/app/grid/11.2.0.3 on a two-node cluster. I started by following Oracle's documentation at http://docs.oracle.com/cd/E11882_01/install.112/e41961/rem_orcl.htm#CWLIN2955 and failed repeatedly. I opened an SR and they sent me the same link and said follow this.

My documentation is attached.

Thanks!

I've done a bunch of PSU applications using a similar process, and I've found that it's really not too complicated to switch the GI home (as long as it works at all <g>). I haven't tested the process of just switching homes but as long as it works in your test like the documentation says, then I wouldn't be suspicious. Alternatively, you could just install 11.2.0.4 into a different directory - like just 11204 or crs11204. Personally, my top level grid directories are like "crs112038r2" where the 8 reflects the PSU number and the revision is for multiple builds (different one-off patches) on the same PSU. In general it's a good idea to follow OFA for directory layouts, but it's not a huge deal to diverge when you have a good reason - and honestly the OFA standards around GI are a still a bit conjectural anyway (IMO).

We had a contractor (no longer with us) who performed an install of GI 11.2.0.3 on a Red Hat Linux 6.4 cluster (2 nodes) into an 11.2.0.4 directory structure (/u01/app/grid/11.2.0.4<http://11.2.0.4%22%20%5Ct%20%22_blank>).



Well, now we want to upgrade from 11.2.0.3 to 11.2.0.4 and are trying to find the cleanest way to do this.  Some ideas have included wiping the host (not preferred), de-installing GI, moving 11.2.0.3 binaries and performing brand new install (as if the original never existed).

A co-worker found the following document from Oracle that talks about changing the GI home path, which seems like the simplest way to do it:
