DTS Error:Cannot Allocate Space, Default Filegroup Is Full

Hi all,

I need to load a table with 820,000 records from a Sybase db via DTS. It always fail with the error:
"Error at destination for row number 820000. Could not allocate space for object in tablespace tempdb
. The default filegroup is full.".

There is only the primary filegroup defined in the db. I've increased the size from 1.5GB to 2GB,
and specify that it shd grow automatically by 10% and there's no limit to the size.
There is still some 28GB in the server, so it should be fine.

It still fail so I added another file to the primary filegroup with size 100MB. Again, it failed with the same error msg.

Where or how else can I increase the tempdb size?

Any help is appreciated.

Thanx,
Jes
