In a system that uses TCP/IP for communication, you cannot detect errors in real time due to TCP/IP limitations. Therefore, a time-monitoring timeout triggers the system to assume that an error has been detected. The OpenTP1 system enables you to specify timer monitoring for each type of processing. You should set an optimum value for each setting.

If an error such as system shutdown occurs in the RAP-processing server system while connection with the RAP-processing server is being established, Java cannot detect the disconnection. In such a case, TP1/Client/J waits until the response wait time specified with the setDcwatchtim method is reached, then returns an error with the exception ErrTimedOutException.
