PQ65343: SUPPORT FOR HTTP SESSION AFFINITY ACROSS MULTIPLE SERVER INSTANCES IN WEBSPHERE APPLICATION SERVER FOR Z0S V4.01

APAR status
Closed as documentation error.

Error description
The restriction that HTTP session data stored in memory can only
be maintained within a single J2EE server instance has been
eliminated. HTTP session data stored in memory can now be
maintained across multiple J2EE server instances. This support
was included in PTF UQ90049 (PTF level L00PTF11). The purpose of
this APAR is to document how to implement that support.

The restriction limiting HTTP session data stored in memory
to a single J2EE server instance has been eliminated.
HTTP session data stored in memory can now be maintained
across multiple J2EE server instances. This support was
included in PTF UQ90049 (PTF level L00PTF11). The purpose
of this APAR is to document how to implement that support.
Problem conclusion
PTF UQ90049 enables WebSphere for z/OS to maintain session data
in-memory across multiple J2EE server instances, as well as
across multiple server regions within a server instance.

A separate document, entitled "WebSphere Application Server
V4.0.1 for z/OS and OS/390: Maintaining Session Affinity Across
Multiple Server Instances, (APAR PQ65343, PTF UQ90049,
Service Level 11)" is available for this APAR. To download the
document, go to 
http://www.ibm.com/software/webservers/appserv/
zos_os390/support.html then click "Product information."
At a later time, the information in this document will be
integrated into the WebSphere for z/OS formal publications.
