Terry,

it looks like you are using datamanager to connect to a DB2 database server?

check the following things:

  1. Is the DB2 server a supported version
  2. is the DB2 client installed on all the reporting servers?
  3. Has the DB2 client the same version as the DB2 server?
  4. Can you connect to this database with the DB2 client installed on the Cognos Server?
