TDMS and Vistex tables

Hi - has anyone ever used TDMS with Vistex tables?

We just did a 3 month time slice and had to remove the Vistex tables because they added up to about 250 GB.  Our Oracle DBA is using Oracle's DataPump to push the data to the client and then will update the client number; it's slow, but no where near as long as it was going to take TDMS.

Which puts the time to do this whole process to over 2 weeks.

Thanks,

Margaret
