EM Gateway Behaves Erroneously If Balance Inquiry Is Sent For A Customer Who Does Not Exist In ECE (Doc ID 2061103.1)

Last updated on OCTOBER 12, 2015

Applies to:

Oracle Communications BRM - Elastic Charging Engine - Version 11.2.0.5.0 to 11.2.0.7.0 [Release 11.2.0]
Information in this document applies to any platform.

Symptoms

On :  11.2.0.5.0 version,

Issue:

EM Gateway goes into infinite loop of resending the request to ECE if the customer does not exist in ECE cache but the PublicUserIdentity exists.

Details:

* This happened after restarting the ECS nodes one after the other during which, some customers were lost during re-partitioning but the PublicUserIdentity remained.
* When a balance inquiry is triggered from BRM through EM Gateway, EM Gateway will retry the request endlessly and not come out at all.
* Also, any other requests tried during this time will also be not processed.

Steps to reproduce:

1. After ECE system is brought up, delete a customer from "Customer" cache leaving behind it's PublicUserIdentity.

           delete from Customer where key()='';

2. Trigger a balance inquiry from BRM through EM gateway for that PublicUserIdentity.

Observe from EM Gateway logs that the request is attempted infinitely.

3. Try triggering a balance inquiry a few times for another customer which is existing in ECE.  This request is not processed consistently.

Expected Behavior:

EM Gateway shouldn't go into infinite loop
