Applies to:PeopleSoft Enterprise PT PeopleTools - Version 8.54 and later
Information in this document applies to any platform.
After upgrading the database from DB2 to MSSQL the SQR Reports are running slowly.
The MSSQL SQR is doing a FETCH-API for every row in the select statements, while the DB2 SQR is doing a single fetch for the select statments.
E.g. The time retrieved shows as follows:
MSSQL with -S option.
Load Lookup Run Time: 8.19
Select Run Time : 1.15
Program Run Time : 9.34
DB2 with -S option.
Load Lookup Run Time: 0.43
Select Run Time : 0.27
Program Run Time : 0.70
The issue can be reproduced at will with the following steps:
1. Login to PIA
2. Navigate to PeopleTools > Process Scheduler > System Process Requests
3. Add a new Run Cntrl ID or use and existing one
4. Run the SQR report(s)
