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

Last updated on AUGUST 07, 2020

Applies to:

Oracle Communications Billing and Revenue Management - Version to [Release 7.5.0]
Linux x86-64


An user has recently migrated from 7.2.1 to 7.5 and currently testing the 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), the main observation was that although Connection Manager (CM) threads were active, only 1-2 were active working on DataBase (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 and/or Data Manager (DM) flow.

The followings are 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
