DSNL515I csect-name TCP/IP BIND FAILED FOR PORT port WITH RETURN CODE=return-code AND REASON CODE=reason-code
Explanation
Db2 encountered an error on the TCP/IP bind socket call while attempting to register a TCP/IP port number with the TCP/IP instance.
- csect-name
- The name of the control section that issued the message.
- port
- The TCP/IP port number that Db2 was unable to register with the TCP/IP instance.
- return-code
- The return code reported by TCP/IP, as a decimal number. This code is issued by z/OS® UNIX System Services or z/OS Communications Server.
- reason-code
- The reason code reported by TCP/IP, as a hexadecimal number. This code is issued by z/OS UNIX System Services or z/OS Communications Server.
System action
The request fails. Db2 will continue to try to activate the TCP/IP port number periodically.
Operator response
Notify the system programmer.
System programmer response
If this error occurs for the TCP/IP port that is used for incoming DRDA requests, the error is probably caused by Db2 restarting on a CEC that already has another Db2 subsystem using the DRDA port number.
If this error occurs for a TCP/IP port that is used for incoming DRDA requests to an ALIAS, the error is probably caused by some of the reasons that an error would occur for the normal DRDA request port. Check to ensure that the port value was also not previously reserved for another application in the system's TCP/IP profile.
Define the TCP/IP port number used by Db2 to the TCP/IP instance, or use the change log inventory utility to correct the TCP/IP port number used by Db2.
User response
Notify the system programmer.
Problem determination
Determine the meaning of the return and reason codes issued by z/OS UNIX System Services or z/OS Communications Server.
