Cognos FM Datasource connection Issues

While setting up new data source connection ( SQL Server DB for example), we get errors in connecting with Cognos Framework Manager"
Login failed
Unable to attach to multi database
 
Few things required to check to resolve such issue
  • Cognos FM is working fine for other data sources from Local Machine
  • Cognos Data source is working fine
  • User is able to connect from DB Client to DB with id.
  • Local ODBC connection name should match with DSN name set up in Cognos Data source
  • Use right ODBC connection file based on which one is set up in Registry. Examples:
 
Win 32-bit in Win64:  C:\Windows\SysWOW64\odbcad32.exe
Win 32-bit in Win32:  C:\Windows\System32\odbcad32.exe
 
 Create shotcut on local desktop for easy access and set up.

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.
