I'm using SSMA for Oracle to load Oracle data onto a SQL2005 server. SSMA runs on the machine that hosts the target database instance. The database has one very large table (only 92K rows, but most rows contain multiple XML-objects). On two consecutive runs the migration of this table was aborted with a messages stating:
DataMigration Error. | Cannot truncate target table. Reason: ExecuteReader requires an open and available Connection. The connection's current state is closed. |
this error message suggests that connectivity to the local SQL Server instance has been lost. Strangest of all is that my first attempt a few weeks ago never had this issue. I'm running SSMA for Oracle V5.2.1259
I searched the web and did find a comparable issue, dated Tuesday, February 14, 2012 1:59 AM. What can I do to avoid this problem?
