Answer


1. Stop the Cognos services.

2. On the Content Manager computer, launch "Cognos Configuration".
  • Click "File - Export As"
  • Choose "yes" (at the prompt) and save the file (for example as "backup.xml" in the c10_location/configuration folder
  • Close Cognos Configuration

3. On the Content Manager computer, create a backup of the following files and directories then MOVE these files and folders to this different location that is secure.

During the crypto keys regeneration process these files and folders will be re-created

The files are:
  • c10_location/configuration/cogstartup.xml
  • c10_location/configuration/caSerial
  • c10_location/configuration/certs/CAMCrypto.status
  • c10_location/configuration/certs/CAMKeystore
  • c10_location/configuration/certs/CAMKeystore.lock
  • c10_location/temp/cam/freshness

The directory is
  • c10_location/configuration/csk

4. In the c10_location/configuration folder, rename backup.xml to cogstartup.xml.

5. Open Cognos Configuration, save the configuration and start the services. On Gateway installation, restart the Web Server.

6. Repeat steps 1 to 5 on all computers that have Cognos Business Intelligence BI Server components installed.
