IC75221: EXCESSIVE LOGGING AFTER JMS FAILURE WITH RETRY DISABLED

Subscribe

You can track all active APARs for this component.

 

APAR status

  • Closed as program error.

Error description

  • If a JMS backend call fails (for example, if a JMS Messaging
bus doesn't exist in an environment), hundreds of Network Error
on Back
interface entries flood the logs.   It appears  that the JMS
continues to retry until the Error rule completes, despite the
fact that retry is disabled for the JMS object. Given the
configuration,
the expected behavior is for only one error to appear in the
logs.

Local fix

  • The issue occurs when remote DNS server cannot resolve the
domain name provided
by WebSphere JMS Endpoint So there is a workaround
that can avoid this issue:

Set "Host Alias" in default domain that can convert the domain
name to assigned
ip address.

Problem summary

  • WHO is likely to see this problem?
DataPower customers using JMS as backend and the JMS object is
unreachable.


WHAT is the problem?
The log will keep generating "Network Error on Back interface"


WHY did the problem happen?
Handle incorrectly when the JMS object is not up due to
connection problem

Problem conclusion

  • 3.7.3.18, 3.8.0.12, 3.8.1.11, 3.8.2.3

Temporary fix
