## Solution

### 11.2.0.3.0

The above error has occurred because of the environment settings. Recently we have upgraded this database from 11.2.0.2.0 version to 11.2.0.3.0 version.

Eventhough CRS is updated with the latest 11.2.0.3.0 home, oratab file is still pointing to 11.2.0.2.0 home. so i have modified it to use 11.2.0.3.0 home and srvctl commands worked like a charm.

mydb_1 @ siodserver4:/u01/app/oracle/diag/rdbms/mydb/mydb_1/trace
> cat /etc/oratab |grep -i mydb
