Defect Information

Defect ID	Headline
CSCvx61202	[BW Eng] AS rollback to R22 failure in DB patch

Problem Description

When certain Cisco BroadWorks patches are applied to the Application Server, attempts to roll back to R22 from later releases will fail.

Background

These Cisco BroadWorks patches will cause issues when you roll the application server back after an upgrade:

• AP.as.23.0.1075.ap375097
• AP.as.24.0.944.ap376682

While the patches are installed, you might experience this senario:

• It will fail to roll back to Release 22 from either Release 23 or 24.

Problem Symptom

Attempts to roll back while the patches are installed will result in an error message similar to this example:

...patching with Rel_23.0/v1.1123/ [failed] (2 errors | 0 warnings) (2 global errors) 

terminating upon error(s)...

applyPatches.sh utility [failed, rc = 2] 

Workaround/Solution

Workaround

This problem is only encountered when you attempt to roll back the system after an upgrade is performed. In order to avoid the issue, simply do not apply the patches listed in the Background section, or ensure they are removed before you perform the upgrade. Note that the faulty patches have to be removed before the upgrade is started even if the issue only happens during the rollback.

Solution

Apply these Cisco BroadWorks patches in order to correct the issues:

Release 22

• There are no patches needed for this issue in Release 22.

Release 23

• AP.as.23.0.1075.ap378987

Release 24

• AP.as.24.0.944.ap378987

BroadWorks patches can be downloaded through the Cisco Software Download Center after you log in with your Cisco.com (CCO) account.

The version of BroadWorks that is currently deployed, as well as the patches currently activated, can be checked by executing the get versions all command from the CLI. More information on how to check the patch level can be found in the Cisco BroadWorks Maintenance Guide.
