Data Guard :: ORA-16401 / Archivelog Rejected By RFS

initial configuration:

cta: physical standby
ctastd: primary

I cancel my failover at cta half way, from [URL]

Quote:

Step 4 Initiate a failover on the target physical standby database.

Issue the following statement to initiate the failover:

SQL> ALTER DATABASE RECOVER MANAGED STANDBY DATABASE FINISH FORCE;

during the above process it took too long so I opened up another session and cancel the above process

SQL>alter database recover managed standby database cancel;

the data guard configuration is left as it is, i.e.

cta: physical standby
ctastd: primary

I discover the following findings in the alertcta.log, i.e. in cta database,

Primary database is in MAXIMUM PERFORMANCE mode

ORA-16401: archivelog rejected by RFS

Cause: An attempt was made to re-archive an existing archivelog. This usually happens because either a multiple primary database or standby database(s) or both are trying to archive to this standby database.

Action: See alert log and trace file for more details. No action is necessary; this is an informational statement provided to record the event for diagnostic purposes.

it seems to be that there are multiple primary database, but it is not based on the information from v$database.Right now the physical standby database cannot received any archive logs from the primary.I've checked the database_role in both servers, they are as they are designated.

from the physical standby database

SYS@cta>select db_unique_name, database_role, switchover_status from v$database;
DB_UNIQUE_NAME DATABASE_ROLE SWITCHOVER_STATUS
------------------------------ ---------------- --------------------
CTA PHYSICAL STANDBY NOT ALLOWED
SYS@cta>alter database recover managed standby database disconnect from session

[code]....

the standby is always busy, i.e. SESSIONS ACTIVE. i.e make sure the archived logs are shipped and apply over to physical standby.

I'm using Oracle 10.2.0.4 and os is windows.
