QlikView Publisher QVD Corruption Recovery

Problem:
 
When Publisher task fails in between for large table due to any issue, it corrupts QVD file. When we try to rerun task after issue resolution, data is lost since QVD was actually incremental load and need to be restored completely.
 
Solution Best Practices:
  • Set up QVD backups and restoration as Enteprise wide solution
  • Identify QVDs having different types of load
  • Document procedure for support and maintenance
Steps:
  • Restore QVD
  • Restart failed task

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

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.
