This article mainly shows you the "NBU backup often see error code analysis and handling methods", the content is easy to understand, clear, hope to help you solve your doubts, the following let the editor lead you to study and learn "NBU backup often see error code analysis and handling methods" this article.

1. The return value is 1mi-the backup part is completed successfully

 if it is an Archivelog backup, and subsequent backups return 1. Typically, Archivelog synchronization of the Oracle database is required.

The method of Archivelog synchronization for Oracle database is:

Log in to the Oracle database service as the Oracle database user and run the following command through RMAN:

$su-oracle

$rman

RMAN > connect target /

RMAN > change archivelog all validate

RMAN > exit

If  is an online full backup of the database, you need to look at the .out output file in the directory where the backup script is located, see which part of the backup is not successful, and then deal with it accordingly.

two。 Status codes 41, 54-connection connection timed out

Check the working status of the server network:

First find the IP address of the server where the backup failed, and make sure that the IP address can be ping.

Using the telnet tool, do the following:

# telnet server IP address 13782

If the returned information is as follows, the VERITAS NBU communication is normal.

Trying...

Connected to server IP address.

Escape character is'^]'.

If the system returns directly to the command line state, check the service and inetd settings of the problem server to ensure that the bpcd process exists.

And check the working status of bpcd using the following command:

# netstat | grep bpcd

3. Status code 96mi-cannot allocate new media for backup, there is no media available in the storage unit

There are no tapes available in the volume pool, and there are no tapes available in the SCRATCH volume pool, so the backup task will have a status code number 96.

4. Status code 219mura-required storage units are not available

Please check the working status of the tape drive and tape.

You need to confirm that the tape drive status is up, the tape library is flashing red, and the tape is stuck in the tape drive.

You can select "Media and Device Management" in the java interface to view the current media allocation.

There are two ways to observe the working status of the tape drive: the Java GUI interface and the command line.

A) Java GUI interface mode:

In the Java GUI interface, you can observe the status of the tape drive in the Media and Device Management  Device Monitor option. For example, tape drive is in use, tape drive DOWN, tape drive idle and so on.

B) Command line mode:

Use the command line mode to observe the status of the tape drive, the related commands are vmdareq, vmoprcmd.

If the tape drive DOWN is observed through the vmdareq, it is recommended that you check for cassette phenomena first. After determining that there is no cassette phenomenon, you can do a simple tape drive UP operation. The tape drive UP operation can be performed through the Java GUI interface and command line described above. Examples of command line methods are as follows:

# vmoprcmd-h hostID-up driveID

Where hostID is the name of the SSO server and driveID is the serial number of the tape drive.

5. Status code 84music-media write error

In general, there is a problem with the tape. Do you need to see if the status of the tape has been marked as FROZEN? If not, you need to bpmedia (manual-freeze-m media_id). Then confirm whether the original content on the tape is useful, and after confirming that it is useless or expired, contact the tape manufacturer to replace the tape.
