This document discusses the necessary steps to take before creating a 11.2 / 11.1 / 10.2 database with 11.2 Grid Infrastructure when Role Separation is in place.
In case of role separation we typically have the following groups and users:
Grid Infrastructure Home Owner : grid
Primary Group : oinstall
Secondary Groups : asmadmin, asmdba, asmoper
RDBMS Home Owner : oracle
Primary Group : oinstall
Secondary Groups : dba, oper, asmdba
In case of stand alone set up, if the 11.2 Database be managed by Oracle Restart ( srvctl stop/start ), then 'grid' user should also be a part of 'dba' group.
The ASM Disks would be owned by grid:asmadmin
11.2 Database
If we create the 11.2 database manually, then before creating the database we need to run the following command:
$ su - grid
$ cd <Grid Home>/bin
$ ./setasmgidwrap o=<11.2 RDBMS Home>/bin/oracle
If we do not do this, database creation will fail with ORA-15025
Pre11.2 Database
Patch 9575578 to the 11.2 Grid Home. After applying the patch run:
$ su - grid
$ cd <Grid Home>/bin
$ ./setasmgidwrap o=<11.1/10.2 RDBMS Home>/bin/oracle
Without the patch script setasmgidwrap will fail with KFSG-00312
