Issue/Introduction

Performance issues in Output Management Web Viewer for users accessing a View® database of PDF reports.

Environment

  • Output Management Web Viewer 12.1
  • Distributed Repository Access System (DRAS)
  • View®

 

Cause

Unfiltered searches search the entire database

Resolution

The resolution for this case is to create searches with filters to avoid unnecessary use of resources .

Any date range greater than 10 days can cause a search Of the entire database. The search is stopped when we buffer enough reports to present to the user in the sysout selection list. If the client's report is not on the selection list and the user hits PF8, the search resumes, until possibly the bottom of Reports. So, a date range larger than 10 days AND a low number of date matches (less than selection screen) will search the entire database then present them to you on the selection list.

OR a date range larger than 10 days and many date matches (enough to fill the selection screen) then the selection list gets presented and the search stops (Not complete). When user hits PF8, the search resumes until we buffer enough matches to present the selection list again or end of list.

In either scenario, the I/O and CPU time will be very close due to search of the entire database.
