Rating Performance: ifw To Reject EDRs On Lock (Similar To Reject On Deadlock) (Doc ID 1308850.1)

Last updated on AUGUST 17, 2018

Applies to:

Oracle Communications Billing and Revenue Management - Version 7.4.0.0.0 and later
Information in this document applies to any platform.

Symptoms

The current locking mechanism used by Discounting in the pipeline rating engine is based on locking the whole balance_group. The lock is maintained for a very short period in order to free the balance_group ASAP. If a balance_group has been locked by the transaction A, a transaction B can lock the same balance_group but, in this case, the transaction B must wait the rollback or commit of the transaction A before to rollback/commit itself.

This mechanism uses dependencies between concurrent transactions. In order to decrease the number of dependencies between concurrent transactions, the FCT_Discount should be able to ignore the EDRs with a balance_group already locked by another transaction and continue processing the EDR file (similar to IgnoreEDROnDeadlock).
