RMAN-06900: WARNING: unable to generate V$RMAN_STATUS or V$RMAN_OUTPUT row

One of my RMAN backup generated below Warnings, here is the detailed description and solution. I hope it helps other users.


RMAN-06900: WARNING: unable to generate V$RMAN_STATUS or V$RMAN_OUTPUT row
RMAN-06901: WARNING: disabling update of the V$RMAN_STATUS and V$RMAN_OUTPUT rows
ORACLE error from target database:
ORA-00604: error occurred at recursive SQL level 3
ORA-04031: unable to allocate 4120 bytes of shared memory ("shared pool","select name,password,datats#...","Typecheck","kgghteInit")
ORA-06508: PL/SQL: could not find program unit being called: "SYS.DBMS_BACKUP_RESTORE"

Cause & Solution:

The RMAN not able to update V$RMAN_STATUS or V$RMAN_OUTPUT due to associated error message. When you receive RMAN-06900 and RMAN-06901error, you need to look for associated error messages to find the root cause of the error message.

In this case, ORA-04031 is the associated error message

ORA-04031: unable to allocate 4120 bytes of shared memory
*Cause: More shared memory is needed than was allocated in the shared pool.
*Action: If the shared pool is out of memory, either use the dbms_shared_pool package to pin large packages, reduce your use of shared memory, or increase the amount of available shared memory by increasing the value of the INIT.ORA parameters "shared_pool_reserved_size" and “shared_pool_size". If the large pool is out of memory, increase the INIT.ORA parameter "large_pool_size".

I have seen many users complaining about error ORA-19921. If you receive this error close some of existing connections or unused RMAN connections.

If your oracle version > then you might be hitting below bugs. These bugs fixed in and higher versions.

ORA-19921: maximum number of 64 rows exceeded - oracle Bug 465973.
ORA-19921: maximum number of 128 rows exceeded - oracle Bug 8264365

  1. I would think most of DBAs now are using spfile as opposed to init.ora! I see you refering to init.ora file..the old way?

    1. Please note that ora-04031 is a standard error, which still have INIT.ORA parameter info. You may get this error when you are using init.ora or spfile for your database.

      I am just referring the parameter file.

      Hope this helps,
