Cognos System Tuning where to start from

Most of the time Cognos system can be tuned in-house if time is spent in below
  • Failure Analysis by using Audit database
  • Reports performance analysis - schedule vs on demand
  • How much data is read by Users queries
  • Cognos Logs analysis to capture any model errors
  • Scheduled Jobs analysis
  • Packages based error trend
  • Space/RAM utilization to identify peak times
With these inputs, first see queries, usages are appropriate and any governance is required. What's being run at peak time and can we distribute schedules (run "all at once" vs in sequence). 

This would be start point to configure Cognos advanced settings, Cognos Environment settings, JVM Tuning for memory, concurrent threads, OS Tuning, DB Tuning and need for any regular Maintenance.

These are quite involved steps but with these checked, we were able to reduce errors, failures by 100 % and pave way towards working on real issues and stabilize BI Platform.

Cognos: How to replace an existing report without breaking links?

Below IBM document explains behavior of copy/move or overwriting impact of objects:- https://www.ibm.com/support/knowledgecenter/en/SSEP7J_11.0.0/com.ibm.swg.ba.cognos.wig_cr.doc/c_gtstd_copy_move_items.html If you copy and overwrite an existing report, the copied report ID and links replace those of the existing report. In this case, you might need to update links, such as links to job schedules. If you move and overwrite an existing report, the existing report ID and links are maintained. In this case, references to the moved entry are broken. However, this doesn't work in all cases and we see drill through links broken in some cases. Best approach in such case is to use cognos deploy method where you update reports in separate folder in same environment and import it to destination location. You can create single export and import tasks to use for all such updates.
