Opens a connection (leaves it open). 2. Opens a command object. 3. Runs 1000 iterations that consist of calling a Stored Procedure (SP) by using the DB2OLEDB driver. 4. Closes the command object. 5. When all iterations are done, it closes the connection object. CAUSE ===== Memory that was being allocated by the agent for the output parameter is not being released correctly.
