PI34044;8.5.5: improve the debug information for ME to ME communication problems

Download


Abstract

In message engine(ME) to message engine(ME) communication for publish subscribe messaging the health of environment is difficult to predict and requires too much tracing.

Download Description

PI34044 resolves the following problem:

ERROR DESCRIPTION:
Improve the debug information for ME-ME message pileup situations.

LOCAL FIX:
None

PROBLEM SUMMARY

USERS AFFECTED:
All users of IBM WebSphere Application Server messaging engines (ME)

PROBLEM DESCRIPTION:
In ME to ME communication for publish subscribe messaging the health of environment is difficult to predict and requires too much tracing.

RECOMMENDATION:
None

In ME to ME communication for publish subscribe messaging the health of environment is a little difficult to determine and requires too much tracing to be enabled to draw conclusions. SIBProcessor=all needed to be enabled on all servers and it was having a huge impact on performance.

PROBLEM CONCLUSION:
With this APAR we have enhanced tracing to capture the summary of communication and print out vital information with minimal overhead.

This new tracing can be enabled with SIBGDHealth=all trace string.

The fix for this APAR is currently targeted for inclusion in fix packs 7.0.0.39 , 8.0.0.11 and 8.5.5.6 . Please refer to the Recommended Updates page for delivery information:
