Client Provided Solution
The client DBA identified that the following query was needed to run CA Service Desk Manager (ITSM) 17.1 efficiently for their needs:
--Manually create the missing index
SET ANSI_PADDING ON
CREATE NONCLUSTERED INDEX [call_req_x201] ON [dbo].[call_req]
INCLUDE ( [id],
[call_back_date]) WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, SORT_IN_TEMPDB = OFF, DROP_EXISTING = OFF, ONLINE = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON)
CA Engineering Review
CA Service Desk Manager (ITSM) should have its database managed like any other application.
It is up to sites to maintain or modify the indices against the database. Indexes may be added or modified as needed to suit. Sometimes it is better to modify an index than add a new one.
This specific change is not going ahead as an index to be brought into the product, as the underlying queries may not be used by other sites, and could waste resources.
There is already present a similar index, _x5, which has as the columns, group_id, active_flag and type.
If index this is already present, but there are still improvements with the new index, then please continue with the plan to add it.NOTE
