Audit Model in 8.4.1

[Anke]

Hi!!
We upgraded from 8.3 to 8.4.1 in January 2011.  I had the Audit model set up in 8.3 and used the auditing reports frequently.  When we upgraded to 8.4.1, for some reason, I was thinking auditing was totally different, and didn't look into upgrading our Audit model.

Now, I am looking into using the Auditing Model again.  We had a consultant doing some misc. Cognos work a few weeks back and he told me I should just be able to update the Audit Model in 8.4.1 and everything would be dandy.

Don't I need to go through the entire setup/install of the Auditing  Model for 8.4.1?  I still have the SQL Audit database (CRN_LOG), but nothing is set up in the 8.4.1 for logging to the database.  What do I need to do to get the audit model up and running in 8.4.1? 

If I go into the Cognos 8.4.1 configuration and add the SQL db under Logging, after I restart the service, are additional tables going to be inserted into the SQL db (as was done when I first set up the database in 8.3)?

I have attached the instruction document I used for setting up Auditing in 8.3

Thank you!!
