About this release

Known issues

The plug-in does not support the following features:


On Windows platforms, the plug-in is unable to ensure that the DB2 Server releases shared memory after running backup or restore jobs. If you stop NetVault Backup Services for any reason and are unable to restart them, stop and restart the DB2 Server to release the shared memory.

16775 (DBG‑189)

The Monitor Job page displays invalid data on Linux Hybrid, HP-UX Itanium, AIX, and Solaris (x86 and SPARC) when they are used with a 64-bit DB2 Server. It displays valid data on Linux Pure64 and Windows platforms.


Restoring Incremental and Delta Backups fails if more than one session was used during the creation of the backups. To avoid this issue, verify that you set the Number of Sessions field in the Default Backup Options - Plug‑in for DB2 to 1 for Incremental and Delta Backup jobs. If the field is set to a different number, the plug-in limits the number to 1, and displays the following message (the backup job completes with warnings):

Backup Option 'Number of Sessions' = '<x>' changed to '1' for 'INCREMENTAL' or 'DELTA' backup

where <x> matches the configured number.


The plug-in uses a DB2 API function to connect to a DB2 Instance. Because of a bug in this function for DB2 9.7, 10.1, and 10.5 on HP-UX Itanium, the plug-in fails to connect. Therefore, the plug-in does not currently support DB2 9.7, 10.1, and 10.5 on HP-UX Itanium.


The plug-in name has been changed to use the “Plug-in for <product>” naming convention (that is, Plug‑in for DB2). If you upgrade the plug-in for a system that is managed by a NetVault Backup Server 9.2, a consequence of the name change is that savesets created with the upgraded plug-in are not displayed in the NVBU Restore window when the Selection Method is set to Plugin; only savesets created with an earlier version are displayed.

Workaround for NetVault Backup Server 9.2: On the Selections tab of the NVBU Restore window, select Job in the Selection Method list to view savesets or backups created with a previous version or the upgraded plug-in.

This issue was corrected in NetVault Backup 10.0.
