codes.
User Response:

| Resource type 230 is temporary file .... this file is not available in your region ...it could have been archived ... this file is required to sort and remove duplicates .... if you index is unique this file is not required and hence you are getting data for query on date .... |

Hi ,
Error is due to workfile tablespaces ( DSNDB07.DSN4kxx ) are not suuficient to sort the non-indexed column for DISTINCT function .
You may have to ask your DBA to increase the number of DSN4K tabelspace for the DB2 subsystem .
Generally , performing DISTINCT function on non-indexed column would not recommended because it would take more cost in sorting .
Thanks

Involved the DBA and sorted out the issue, the workfile was reallocated and now we are up again.
Thanks for the information it was a good learning experience |
