BUG REPORT: NetBackup for Microsoft SQL Server, or NetBackup for Oracle database agents, or user initiated backups are failing with Status Code 41 after upgrading to NetBackup 6.5, 7.0, 7.5 or


There is an incorrect DLL reference in the <install_path>\Veritas\NetBackup\nblog.conf file on the master.

The default entry for KeyName:Default.L10nLib in the nblog.conf file after the upgrade is:


 NOTE:  In most cases, <install_path> is C:\Program Files

 E.g.,  Default.L10nLib=C:\Program Files\VERITAS\NetBackup\bin\vxextwincat.dll 


Bug: 1987535

After an upgrade from NetBackup 6.0, some database and user-initiated backups may fail.  The nbjm process fails to write any messages to the progress and comm files on the client host, and the data flow never starts.

Child application jobs will show as active in the Activity Monitor and the job details will show that tapes will have been mounted and positioned, but there will be no further progress updates after the Begin Writing notification.

Normal file system backups that are initiated from the master to the same client are successful because they do not rely upon progress or comm file updates to initiate the data transfer.

Log Files:
The following log sequences show the nbjm process encountering a failure, which then leads to a dbclient timeout while awaiting for the missing comm/progress log updates.

The nbjm (OID 117) debug log shows a failure while attempting to perform the update to the comm file.

The dbclient log shows an error after CLIENT_READ_TIMEOUT expires without the expected update to the comm file.

For machines which have been upgraded to NetBackup 6.5, confirm that <install_path>\VERITAS\NetBackup\bin\vxextwincat_1.dll exists on the master server.  If it does, follow this procedure:

1. Open a Command Prompt
2. Change directory to <install_path>\Veritas\NetBackup\bin
3. Execute the following command:
vxlogcfg -a -p 51216 -s Default.L10nLib="<install_path>\Veritas\NetBackup\bin\vxextwincat_1.dll"
NOTE:  In most cases, <install_path> is C:\Program Files
For NetBackup 7.0, confirm that <install_path>\VERITAS\NetBackup\bin\vxextwincat_3.dll exists on the master server.
1. Open a Command Prompt
2. Change directory to <install_path>\Veritas\NetBackup
3. Execute the following command:

vxlogcfg -a -p NB -o Default -s L10nLib="<install path>\Veritas\NetBackup\bin\vxextwincat_3.dll"

If successful, the following message should be displayed:
The configuration settings were added successfully.

After running the above command, be sure to verify the correct path was added to the nblog.conf file by opening it in a text editor (such as Notepad) and finding the vxextwincat substring.  Compare it to the appropriate KeyName listed above for the version of NetBackup being run.

Note: It is not recommended to edit/modify the nblog.conf file using a text editor as this may corrupt the file.  After viewing this using a text editor, make sure to not save the file before closing it.

Note: It is necessary to stop and restart nbjm (or all of NetBackup) on the master server to pickup the change.

Then, retry the failed backup - it should succeed.
