ORA-01153: an incompatible media recovery is active

user11952526Feb 19 2013 — edited Feb 26 2013
Hi,

My database version is 11.2.0.1.0 running on AIX 64-bit.
When I am trying to keep my standby database in managed mode getting the following error... but archives are getting applied.
=======================================================================================================================================
SQL> ALTER DATABASE RECOVER MANAGED STANDBY DATABASE DISCONNECT FROM SESSION;
ALTER DATABASE RECOVER MANAGED STANDBY DATABASE DISCONNECT FROM SESSION
*
ERROR at line 1:
ORA-01153: an incompatible media recovery is active
=======================================================================================================================================

Did the following...
1. Cancelled the recovery.
2. shutdown the standby database.
3. Startup the standby DB in NOMOUNT.
4. Then in mounted - ALTER DATABASE MOUNT STANDBY DATABASE;
After starting the STANDBY DB in MOUNT, automatically archives were getting applied. I observerd that MRP0 was started.

SQL> SELECT PROCESS, STATUS, SEQUENCE# FROM V$MANAGED_STANDBY;
