After I had installed RDBMS 11.2.0.1 (See Install Oracle RDBMS 11.2.0.1.0 with Grid Infrastructure), I relised that I had installed the wrong Oracle version (11.2.0.1 instead of 11.2.0.3), and I had to de-install RDBMS 11.2.0.1.
RDBMS 11.2.0.1 installed
Ran the following commands on GRIDCTRL:
export ORACLE_HOME=/opt/oracle/app/product/11.2.0/dbhome_1/export ORACLE_BASE=/opt/oraclecd $ORACLE_HOME/deinstall/./deinstallThe log is attached as Deinstall_DB_11_2_0_1_grid.
