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

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 Messaging Engine to Messaging Engine 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:
