The following shows notes on using the XATMI interface for TP1/Client.

• Be sure to specify the following values in the definitions when using the XATMI interface under transactions:
  Specify a value other than zero for the DCCLTTREXPTM or trn_expiration_time.
  Specify Y for the DCCLTTREXPSP or trn_expiration_time_suspend.
  
• If the blocking status that occurred during data transmission by the tpconnect or tpsend function is not canceled after a certain period of time, TPESYSTEM is returned regardless of whether blocking is specified.
• If the timeout error occurred for the transaction branch expiration time, the CUP execution process terminates abnormally without returning TPETIME. In this case, all the connections established before the timeout error are disconnected and no longer available.
• If a timeout error occurred for the maximum time interval in permanent connection, all the connections established before the timeout error are disconnected and no longer available.
• If a communication error occurred in the connection between the CUP and the CUP execution process, the CUP execution process terminates abnormally. All the connections established before the timeout error are disconnected and no longer available.
• Specify DCCLTXATMI=Y in the client environment definition.
