PK11928; 5.0.2: Additional information to dynamic
cache in push-pull environment
Downloadable files
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.
