PK80196; 7.0.0.1: 404 error response sent by sip proxy during sip container fail

Download Description

PK80196 resolves the following problem:

ERROR DESCRIPTION:
When a Session Initiation Protocol (SIP) container goes into failover, the SIP proxy returns back 404 error responses to SIP requests that contain affinity to the failed server. It should be suspending these until the peer SIP container has taken over the failed servers sessions.

LOCAL FIX:

PROBLEM SUMMARY

USERS AFFECTED:
All users of IBM WebSphere Application Server V7.0

PROBLEM DESCRIPTION:
The Session Initiation Protocol (SIP) proxy was not correctly catching all affinity lookup failures.

RECOMMENDATION:
None

The SIP proxy was not correctly catching all affinity look-up failures and suspending the processing of these SIP requests until the SIP container's peer server has taken over the sessions of the failed server.

PROBLEM CONCLUSION:
The SIP proxy is now catching all affinity look-up failures and suspending the processing of these SIP requests until failover has completed. Once failover has completed the SIP proxy resumes the processing of the suspended SIP requests which are then sent to the SIP container that activated the SIP sessions of the failed SIP container.

The fix for this APAR is currently targeted for inclusion in fixpack 7.0.0.3. Please refer to the Recommended Updates page for delivery information:
