NetVault Plug-in for Oracle 12.2

Table 5. Troubleshooting backup failures
Error	Explanation
ORA-00245: control file backup operation failed	For RAC environments that use Oracle 11g Release 2 or later, ensure that the snapshot Control File is shared by all nodes in the RAC database. Check the CONFIGURE SNAPSHOT CONTROLFILE NAME TO parameter to determine the current setting. For more information, see Installation prerequisites.
ORA-01031: insufficient privileges on Oracle Backup error	User name specified in the Oracle SYSDBA User Name field of the Add, or Edit, Oracle Database dialog box must have SYSDBA privileges, be included in the Oracle Password File, or be a member of the ORA_DBA OS group. Additionally, if the SYSDBA user is specified in the Oracle Password File, the Use Oracle Password File Authentication option should be selected in the plug-in’s Configure dialog box.
Failed to Connect to Database or ORA-01034: Oracle is not available	Oracle Instance specified in the Oracle SID field of the Add, or Edit, Oracle Database dialog box must be in an OPEN state. The instance must be in an OPEN state to perform backup.
ORA-01123: Cannot start online backup; media recovery not enabled	Oracle Instance is not running in ARCHIVELOG mode as specified in Prerequisites.
RMAN-06062: cannot backup SPFILE because the instance was not started with SPFILE	If either Control File Autobackup Enabled or Use RMAN Commands to backup SPFILE are selected on the Add, or Edit, Oracle Database dialog box, the database must be started with an SPFILE. Create an SPFILE and restart the instance using the SPFILE or use the Edit Oracle Database option to clear these two options and insert the path for the PFILE in the Parameter File(s) Path field.
RMAN-06180: incremental backups require Enterprise Edition	For editions other than Oracle Enterprise Edition, Incremental Cumulative and Incremental Differential backups are not supported. Select either Full or Incremental Level 0 for the Backup Type.
RMAN-06181: multiple channels require Enterprise Edition	Ensure that Number of Channels is set to 1.
Failed to back up all data	If the SYSDBA password has been changed on the Oracle Server, it must be updated in the plug-in’s Database Configuration. For more information, see Removing a saved password.
Flash Recovery Area Backup Fails with 'specification does not match any datafile copy in the repository' or 'specification does not match any backup set in the repository' errors.	A Flash Recovery Area backup was performed; however, the FRA does not contain any recovery files for previous backups that were performed with a Backup Destination of Disk or Both NetVault Backup Media Manager and Disk. You must use the FRA as a Backup Destination before you can perform a backup of the FRA with the Flash Recovery Area backup type.

Backup job hangs

Problem

There is a lock on the Control File and a backup job hangs at log output: “Log Message: Starting Control File and SPFILE Autobackup at <date>.” Or this job is canceled and a subsequent backup job completes with an error message in the log of the job: “ORA-00230: operation disallowed: snapshot control file enqueue unavailable.”

Possible causes

•

Plug‑in for Oracle has not been properly configured; that is, the NetVault Backup Server field has not been set on the Configure dialog box.

•

Control File Autobackup has been enabled without proper configuration of the plug-in.

Resolution

Cancel the hung backup job.

Remove the lock on the Control File.

Start SQL*Plus, and connect with administrator privileges to the local instance.

SQLPLUS SYS AS SYSDBA

Verify that there is a lock on the Control File, and obtain the offending SID with the following query:

SELECT s.SID, USERNAME AS "User"

FROM V$SESSION s,V$ENQUEUE_LOCK l WHERE l.SID = s.SID

AND l.TYPE = 'CF' AND l.ID1 = 0 AND l.ID2 = 2;

In the following example, the offending SID is 133.

SQL> SELECT s.SID, USERNAME AS "User" FROM V$SESSION s,

V$ENQUEUE_LOCK l WHERE l.SID = s.SID AND l.TYPE =

'CF' AND L.ID1 = 0 AND l.ID2 = 2;

SID User

-------- -------------------

133 SYS

SQL>

Obtain the Process ID (SPID) that matches the SID with the following query:

SELECT s.sid,p.spid

FROM v$process p, v$session s

WHERE p.addr = s.paddr order by s.sid;

In the following example, the offending SPID is 3184.

SQL> SELECT s.sid,p.spid FROM v$process p, v$session s

WHERE p.addr = s.paddr order by s.sid;

SID SPID

-------- -------------------

Exit SQL*Plus, and stop the Process in the OS shell:

Kill -9 <spid>

Example:

SQL> exit
