Troubleshooting Tips Senders and Receivers Falling out of Sync with Incremental Control Numbers When the sender and receiver have all control number checking options set to incremental, it is possible for a sender to increment their control numbers and fail to send to the receiver. In this case, the receiver would have received some transactions, and then miss some, and then start receiving them again. This leads to a gap in the control numbers received which causes control number validation to fail on the receiving end. Example: 1. Sender sends transaction 1 with control numbers 1,1,1. 2. Receiver receives transaction 1. 3. Sender increments control numbers for transaction 2: 2,1,1, but fails to actually send transaction 2. 4. Sender sends transaction 3 with control numbers 3,1,1. 5. Receiver receives transaction 3. Control number validation fails because the receiver never received transaction 2. If this occurs, perform the following: Execute the following SQL statement at the receiver side, assuming that the sender's domain identity is 01, Interchange Sen: delete from tibedi_control_number where partner_qual='01' and partner_id='Interchange Sen' and direction = 'I'
