What version of PMF are you working with?
The fact the message is "DB not available" possibly indicates a physical connection error. Or it could indicate there was a problem running the SQL scripts (DDL) to create the DB. Make sure the DB/2 console didn't throw any errors when you ran the SQL Script. Follow the directions for setting up DB/2 security and table/index space in comments in the DB2.SQL script.
We're assuming you have taken PMF out of the way and made sure you can physically access the data mart from WebFOCUS. You know you need a DB/2 client from IBM for accessing the DB installed on your WebFOCUS server (and that it should be the same version as the server), and to have that client configured to access your DB/2 RDBMS. Then the WebFOCUS server adaptor connection needs to be configured to talk to the data mart, which means the security credentials must match.
Finally you should run PMF against the data mart using an administrator log-on (the default is pmfadmin and should already be set up in your MR environment). First time you log on you should get a request from PMF to resync. Do that and enter any additional DB info as prompted fully and accurately.
Lastly, if you want to run the CentCorp demo using DB/2 you will need to restore a snapshot of the centcorp DB, once the entire connection is set up. PMF 5.2.1 ships with a snapshot of centcorp and you can restore it by running the PMF Administration Console.
If this does not help, please contact technical support, as the forum is limited in the ability to offer that kind of help.
Hope this helps.
