My Cognos has fallen AGAIN and can't get up

We saw this problem: -

CAM-CRP-1280 An error occurred while trying to decrypt using the system protection key. Reason: javax.crypto.BadPaddingException: Given final block not properly padded 

again today, on another IBM Business Monitor 8.5.5.0 environment.

Again, it was due to our moving an AIX LPAR from one p780 server to another.

So there's something in Cognos that REALLY loves the underlying hardware, assumedly an AES encryption key.

Still, the solution was the same - force the Cognos configuration under Monitor to rebuild.

Thankfully, my previous blog post: -

helped immensely.
