Running Data Studio 4.1 on Linux 64 and DB2 v9.7.
The instance name that DS identifies is completely wrong (it should be db2inst1) - it is 18446744073709551615 (which is 2^64 -1) - see pic.
This obviously messes up any comms. Any clues as to where it getting this value from?
DB2 control center does not suffer from this issue.
