Solution 1961308.1 : Back-to-back Purge UE Requests (PUR)

Applies to:

Oracle Communications Subscriber Data Management (SDM) - Version SDM 9.0.3 and later
Information in this document applies to any platform.

Symptoms

Quota Reset is not done properly due to 2 PURs arriving to Subscriber Profile Repository (SPR)in less than 100ms, it causes second PUR to be answered with Out-Of-Sync by SPR.

Cause

Quota Reset is not done properly due to 2 PURs arriving to SPR in less than 100ms, it causes second PUR to be answered with Out-Of-Sync by SPR, it requires Multimedia Policy Engine (MPE) to send an User-Data-Request (UDR) to request for the proper sequence number however the new PUR send by MPE does not have the proper information due to MPE no storing the previous information (send in previous 2 PURs) and it is the reason quota reset no working properly.

This problem would be fixed in MPE release 10.5

Solution

Force SPR to read the active database whenever a PUR is received.

Such an option is available only in BlueVersion 9.0.5 patch2 ( patch 7) and in BlueVersion 9.3.1 Patch 1, however; it requires verification that the system can support such an option. So whenever such situation exists, it is recommended to open a Service Request (SR) to study the system where problem is observed.
