[theecw]

Hi All!

am new in this forum and i wish you help me with this issue.

I try to connect the source data with framework manager but when i connected i got this error QE-DEF-0368 Unable to decrypt user name and password credentials from the content store.

I found a solution from IBM support said;
. Close Framework Manager and stop any Cognos ReportNet or BI Server service on the laptop.

2. Open Windows Explorer and navigate to <install location>\crn\configuration directory.

3. Delete these three folders: csk, encryptkeypair, signkeypair.

4. Open Cognos Configuration, input the configuration of the target server, and click Save.

5. Start Cognos ReportNet or BI Server service and retry connecting with Framework Manager.

So i deleted the CSK folder and other but now cognos configuration is not working anymore
its show me this error when i tried to start the server, it  said " Problems were encountered during validation.CAM-CRP-1064 Unable to process the PKCS #7 data because of an internal error.

Hi,

Rename cogstartup.xml to something different, then launch Cognos Configuration. This will generate a new, blank config. Re-enter all your environment URIs and configure your content store connection and authentication provider / email server as before. When you press save and start it should then regenerate your cryptographic keys.
