How can I resolve this issue?

Environment

TDM 4.X using Oracle as the TDM repository

Cause

Issue is that the TDM Portal process may create a temporary table to assist with test matching in your target database.  If the process is killed,  the temporary table will be left in the target database,  and will prevent future test matchings from taking place in your target database.

Resolution

To resolve this issue,  you will need to do the following.

1) Open your favourite SQL Query tool, connect, and browse for tables in your target database that you are test matching with.

2) In your table view,  look for a table name that begins with "FNV_".   If you find a table with this prefix,  delete it.

3) Publish your job,  and verify the removal of the temporary table has addressed your issue.

Additional Information

If you do not find a tablename in your target database with FNV,  and this error still happens when creating a test match with the TDM portal,  please reach out to support for assistance on this issue.
