Abstract
The Dynacache APAR PK10276 requires additional information from the Data Replication Service (DRS) replication layer.
 
Download Description
PK11928 resolves the following problem:

ERROR DESCRIPTION:
To improve performance and decrease memory overhead in the Dynacache push-pull environment, new information must be exposed by DRS to Dynacache.

LOCAL FIX:

PROBLEM SUMMARY

USERS AFFECTED:
IBM® WebSphere® Application Server V5.0 users of Dynacache with replication.

PROBLEM DESCRIPTION:
The Dynacache APAR PK10276 requires additional information from the Data Replication Service (DRS) replication layer.

RECOMMENDATION:
None

Dynacache APAR PK10276 changes the code to compress two separate maps into one, but this requires the DRS replication layer to expose additional information on the shared map. This single map allows a smaller memory footprint for the Dynacache push-pull replication environment.

PROBLEM CONCLUSION:
DRS now exposes more information on the single map for the use of Dynacache. This APAR is merely supporting changes for PK10276.

The fix for this APAR is currently targeted for inclusion in versions 5.0.2.14 and 5.1.1.8.
