DB2 11.1 version is not certified with current version of UIM . DB2 11.1 is not yet tested in our QA environment for certification.
This indicates a possible DB2 configuration issue and needs populating the catalog properly.
The db2 client MUST be configured to access this instances via the catalog before the probe can work. Please engage your DBA for proper setup of the db2 probe for communication to the database.
Supported version did not have a problem. For unsupported DB2 database version please turn the catalog off on the problem DB2 client server and will start monitoring it remotely .
IBM has plenty of docs on this
