I have an installation of Cognos BI 10.2.1 (Windows 64 bit) which was recently upgraded with Fix Pack 6. I had already restarted the Cognos service after installing this Fix Pack and everything seemed fine.
Today I was notified that no users could open Report Studio. Attempting myself, I got the message CAF-WRN-2082. I looked in pkiauth_6-3-2015.log and found this:
(19:14:24)pkiauth.logon theAuthRequest: com.ibm.cognos.camaaa.internal.common.IBiBusHeaderCompatibilityAdapter2@c2120665
(19:14:24)REMOTE_USER header did not contain an EDIPI. Aborting logon.
(19:14:24)Contents of header:
(19:14:24)Exception details: null
Not having any idea what the problem might be, I decided to try restarting the service, which often resolves mysterious errors. I opened IBM Cognos Configuration and clicked the Restart button. It stopped for a long while having displayed "camAsyncService, StartService, Success". During this time I saw that the pkiauth file was growing rapidly. It finally gave up with the message: "CFG-ERR-0106 IBM Cognos Configuration did not receive a response from the IBM Cognos service in the time allotted."
Looking in the pkiauth file I see numerous instances of this:
(19:42:53)pkiauth.logon theAuthRequest: com.ibm.cognos.camaaa.internal.common.IBiBusHeaderCompatibilityAdapter2@84c403a4
(19:42:53)REMOTE_USER header did not contain an EDIPI. Aborting logon.
(19:42:53)Contents of header:
(19:42:53)Exception details: String index out of range: -10
At this point I have no idea what could be wrong. I have not made any configuration changes since installing the last Fix Pack. I would appreciate any suggestions.
Is it a single server install ? Was the fix pack applied across the board, in case of a distributed install?
