Poor Performance of Billing Process upon 7.2.1 to 7.5 Upgrade
(Doc ID 1589440.1)

Applies to:Oracle Communications Billing and Revenue Management - Version 22.214.171.124.0 to 126.96.36.199.0 [Release 7.5.0]
The user has recently migrated from 7.2.1 to 7.5 and currently testing Billing process. When attempting to run billing for a large account in an upgraded 721 to 75 on Exalogic, there was performance issues.
The performance of the billing process was rather slow (currently 20-50 bills per minute), and the main observation was that although CM threads were active, only 1-2 were active working on DB at a time.
Please help to understand the root cause and improve system performance. Also, please suggest better configuration numbers based on the total number of transaction processed through this CM/DM flow.
The followings were the current configuration:
- pin_billd children 5
- pin_mta children 12
- pin_bill_accts children 40
- dm dm_n_fe 16
- dm dm_bigsize 805306368
- dm dm_max_per_fe 48
- dm dm_n_be 256
- dm dm_shmsize 2147483648
- dm dm_trans_be_max 180
