ORA-27191: sbtinfo2 returned Error Tips

Expert Oracle Database Tips by Donald BurlesonJanuary 10, 2015

ORA-27191: sbtinfo2 returned Error Tips

Question: I am taking a backup via RMAN.  While running the backup, I am getting getting an ORA-27191 error.  The content of the ORA-27191 error stack is shown here:

RMAN-00571: =========================================================== RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS =============== RMAN-00571: =========================================================== RMAN-03009: failure of delete command on ORA_SBT_TAPE_1 channel at 01/09/2011 20:27:10
ORA-27191: sbtinfo2 returned error

How do I resolve this ORA-27191 error?

Answer:  The oerr information on the ORA-27191 says the following:

ORA-27191: sbtinfo2 returned error

Cause: sbtinfo2 returned an error. This happens while retrieving backup file information from the media manager's catalog.

Action: This error is returned from the media management software which is linked with Oracle. There should be additional messages which explain the cause of the error. This error usually requires contacting the media management vendor.

The ORA-27191 is an error thrown by an underlying software, either the MML or TMS layers that manage the backup media (tape or disk).

First, check that your Media Management Library (MML) software is installed properly:

 oracle> ls -l $ORACLE_HOME/lib/

If you are using Tivoli, use the following command to check the install of the MML:

oracle> ls -l /usr/tivoli/tsm/client/oracle/bin64/tdpo-hrepint9-BUOn.opt

 Then, check the Tape Management System (TMS) logs to look for the actual error and take appropriate steps to eliminate the issue at that level.
