I was whining a lot lately about yk-err-0001 error in Cognos related to Microsofts SSAS and Cognos load balancing. Today is time for the final chapter of this babble! It has finaly been solved- for real this time!
If you're currious, here is the original post with a temp workaround solution. If you are ready to fight this issue till the end - grab a seat and read on ;)
Why a seat? Because it's a lot of work waiting for you :)
To be realy honest, after loosing all hope to solve this matter in a civilized way, we did a mass cleanup- completely reinstalled OS on all servers and at the same time upgraded Cognos to version 8.4.1. That is it! No more issues with SSAS and load balancing! Have no idea whether it was general reinstall that helped or if it was the version upgrade that fixed a mysterious bug in Cognos load balancer... But the whole thing was surely worth the effort!
More details on the upgrade from 8.4 to 8.4.1 are getting ready to be published any day now. Want a sneak preview- no major pitfalls!
