I am trying to use DB2 Enterprise stage. The DB2 is setup on remote server, DataStage version is 8.1, DB2 client version is V9.5. Db2 Server version is also 9.5.
The job has a DB2 enterprise stage and a Dataset..I am trying to fetch records from a table using Select query and o/p the records to the dataset

I am getting following error

SQL1024N: A database connection does not exist

That's because a database connection does not exist. Maybe all available connections are in use, maybe the connection is not properly configured. It's up to you (maybe with DBA help) to determine why a database connection does not exist.
