One listener is failing at startup and we are receiving the following message:
DC088000 V2 T19 #SOCKET FUNC=BIND ,R15=00000000,RC=FFFFFFFF,ERRNO=00000111,RSN=744C7246,PTE=TCPCER1
The ERRNO 111 indicates permission is denied to access the port.
RSN=744C7246 the 7246 indicates JRPortAccessAuth User does not have
authority to access the port.
Is the port an SSL port or in use by another application? This is usually the reason for these access errors.
To determine if another application is using this port, you can view your TCPIP.PROFILE file. The TCPIP.PROFILE file contains a list of predefined listener ports for the stack. If you browse this file, the reserved ports would be in section 'Reserve PORTs for the following servers.'.
The other scenario is usually a problem with the IBM security on the mainframe.
These abend codes are documented in the CA IDMS Callable Services Guide, appendix A, TCP/IP Error Codes.
