Last updated on DECEMBER 01, 2023

Applies to:

Oracle Communications BRM - Elastic Charging Engine - Version 11.3.0.6.0 and later
Information in this document applies to any platform.

Goal

On Oracle Communications Elastic Charging Engine (ECE) 11.3.0.6.0 version, High Availability:

It is observed that the sharing lock is not removed when the node is crashed.

Below are observations based on the node crash due to side effect of parallel incremental loading and billing run:

- Long Garbage Collection (GC) happened due to memory constraint on couple of nodes.
- Nodes were evicted from the cluster.
- Locks existing on the SharingCustomerLock remained and not cleared.
- Locks were existing on CustomerInBrmTransactionLock.
- Reloading accounts cleared the lock on CustomerInBrmTransactionLock but not from SharingCustomerLock.
- That caused failures in multiple orders/billing.
- Manual clearing of sharing lock has helped to fix the order/billing.
- Here it is observed that lock from sharing cache has not been removed and also incremental loading has not cleared the sharing lock.

- It cancelled the start due to timer.
