TCP Interface Messages

The following table describes the messages that pertain to the Substation ES TCP Interface.

Code Description
SXB2000I IId:Intf-Id Connect to TCP host-name:port Starting
Explanation: This message appears at initialization time when the application is connecting to a TCP listener. host-name is the LPAR name, and port is the port you specified in the TCP interface parameters.

User Response: This is a mandatory message to show TCP startup.

System Response: None.

Destination: Log and trace files.

SXB2001I IId:Intf-Id Connect to TCP host-name:port Complete
Explanation: This message appears at initialization time when the application has successfully connected to a TCP listener. host-name is the LPAR name, and port is the port you specified in the TCP interface parameters.

User Response: This is a mandatory message to ensure that TCP is connected.

System Response: External applications or WebUI can now communicate with Substation.

Destination: Log and trace files.

SXB2001E IId:Intf-Id Connect to TCP host-name:port Failed Rsn:RSN
Explanation: This message appears at initialization time when the application connection has failed. host-name is the LPAR name, and port is the port you specified in the TCP interface parameters.

Possible reason codes are as follows:

  • 10 (RSN_NAME_RESOLUTION_ERROR)

    Invalid URL

  • 14 (RSN_SERVER_FAILED)

    Configuration error

    Failure to set the stack name

    TCP service already initialized

    Failure to open log file

  • 15 (RSN_SOCKET_ERROR)

    Internal (socket error)

  • 18 (RSN_GSK_ERROR)

    TLS-related error

User Response: Refer to the reason code to possibly diagnose and correct this failure.

System Response: Connection is not established.

Destination: Log and trace files.

SXB2050I IId:Intf-Id User user-name from client-name Authenticated
Explanation: This message appears when a remote user has connected to the host system. user-name is the z/OS user ID that is used, and client-name is the client host name where the request originated from.

User Response: None.

Destination: Log and trace files.

SXB2051E IId:Intf-Id Password Decryption Failed RC:RC
Explanation: A service or WebUI has specified an incorrect port number for the same host on which TCP/IP serves multiple connections. Most likey WebUI tried to connect to Substation using an incorrect port. There are two host numbers: 1 is for Substation and 2 is for Mainframe RED.

User Response: Normally this is an incompatibility issue or a system error. Contact TIBCO Support and supply the message associated with this issue.

System Response: Authentication failed.

Destination: Log and connecting application.

SXB2052E IId:Intf-Id Host validation failed RC:RC
Explanation: A user authentication request for z/OS sent from a remote application failed. The return code is sent back to the user application.

User Response: Ensure that the user user ID and password are valid, and the user ID is active in z/OS host system.

System Response: Authentication failed.

Destination: Log and connecting application.

SXB2053E IId:Intf-Id Failed to deliver Response. Thd:number
Explanation: Substation was notified by TCP that a response failed delivery. The thread number from where the response was sent is supplied.

User Response: Contact TIBCO Support and supply the associated log file.

System Response: None.

Destination: Log and trace file.

SXB2055E Incorrect target system reached #number
Explanation: A service or WebUI has specified an incorrect port number for the same host on which TCP/IP serves multiple connections. Most likey WebUI tried to connect to Substation using an incorrect port. There are two host numbers: 1 is for Substation and 2 is for Mainframe RED.

User Response: Ensure that you have the correct port number specified in WebUI or your application calling Substation.

System Response: The connection request is rejected.

Destination: Log and connecting application.
