Query Causing Excessive CPU During Business Hours (Doc ID 2688809.1)

Last updated on JULY 14, 2020

Applies to:

Oracle Communications Billing and Revenue Management - Version 7.5.0.21.0 and later
Information in this document applies to any platform.

Goal

The following query seems to be causing excessive CPU usage during business hours:

SELECT DISTINCT collections_action_t.poid_DB,
  collections_action_t.poid_ID0 ,
  collections_action_t.poid_TYPE ,
  collections_action_t.poid_REV
FROM collections_action_t ,
  collections_scenario_t
WHERE collections_action_t.account_obj_ID0 = :1
  AND collections_scenario_t.exit_t = :2
  AND collections_action_t.scenario_obj_ID0 = collections_scenario_t.poid_ID0
  AND collections_action_t.status = :3
  AND config_action_obj_id0 IN ( 926, 850, 851 )


The user's DataBase Administrator (DBA) has recommended the following index for better performance, which has been tested in non-prod and results are expected.

PIN.COLLECTIONS_ACTION_T(ACCOUNT_OBJ_ID0, CONFIG_ACTION_OBJ_ID0, STATUS)


Would Oracle also aligned with this recommendation?
