CPU Is Not Reduced When Use Push Replication

(Doc ID 1504544.1)

Last updated on NOVEMBER 16, 2012

Applies to:

Oracle Coherence - Version 3.7.1.4 and later
Information in this document applies to any platform.

Symptoms

While using Push Replication, high CPU is observed on one of the coherence nodes.

Example :

When we try to save object using write-behind and push replication ( say siteA and siteB ) using 50 requests/sec for 60min.

CPU usage on one of the storage node in siteA and B are not reduced while the others are reduced.

The result is same even after 15hours of testing.

If the test is done without push-replication the issue is not seen.

If the test is done with write-through then the issue is not seen.
