What Does the DTCTester Tool Do?

  • Establishes a connection to SQL Server by using a data source name (DSN) and username and password that you provide on the command line by using the default network library.
  • Creates a temporary table.
  • Enlists the connection in a transaction.
  • Does an insert on the temporary table.
  • Commits the distributed transaction.
  • Selects inserted value to make sure it was committed.
  • Closes the connection.
