[JMS] Consumer Drops From One of The Uniform Distributed Queue Members

(Doc ID 1463731.1)

Last updated on NOVEMBER 05, 2016

Applies to:

Oracle WebLogic Server - Version 10.3 and later
Information in this document applies to any platform.
***Checked for relevance on 2-Jan-2015***

Symptoms

Create two WebLogic Server domains.

Flow of message and architecture will be something like the following: MDB Producer -->> Weblogic Server -->> UDQ(Cluster C1[MS1 and MS2]) <<------>> FJMS-->> single server 'FJMS1'-->>MDB Consumer

Configuration of domain 1

Configuration of domain 2

Start the servers sequentially, first MS1 then MS2 and then FJMS1 and you will see consumer from one of the UDQ member drops. See consumer current count in below snapshot. One member of the UDQ has 16 consumer and another member has zero consumer. 

The reason why we say the consumer dropped from the UDQ member is that the MDB consumer is able to make the consumer on both the UDQ members first but later it drops from any of the UDQ member. This is evident from the consumer high and consumer Total as they both shows 16 consumers.
