Hi List,

maybe some RAC-guru can help me:
Config: 2 node RAC (Solaris_at_SPARC) several DBs there, one particular
Instance1: CDB111T11
Instance2: CDB111T12

currently, both instances are using the
ORACLE_HOME=/appl/oracle/product/11107 (local installed on every node)

I would like to do the following steps:
1) install a new O_H on both nodes: /appl/oracle/product/11107_PATCH (with PSU - this patch is marked as "rolling RAC installable")
2) shutdown Instance1 CDB111T11
3) change the config for Instance1 to use the new O_H

3) startup Instance1
4) shutdown Instance2 CDB111T12
5) change the config for Instance2 to use the new O_H


6) startup Instance2
7) run the post-sql "_at_catbundle.sql psu apply" on Instance2

I just does not know how to change the O_H on a per Instance base; srvctl modify seems to only let me chose one O_H per database (which is a nonsens in my opinion).

can someone please help me if (and how) step 3 and 5 is possible?

thank you,
