Defining socket addresses

Defining socket addresses

You identify each target server running Download for z/OS® by the socket address at which the server waits for data. The socket address identifies both:

  • The IP address of the remote host
  • The port number through which the target server communicates with TCP/IP

The administrator of the remote system assigns the socket address by using port numbers that are not reserved or used by other applications on the target system. The valid range of port numbers is: 5002 - 64000, except 8251 and 8253, which are not allowed. Also, avoid 6874 - 6889, which InfoPrint Manager uses for other purposes, and 15080, which Ricoh ProcessDirector uses.

Download for z/OS running on the local z/OS system must use the same port number as the remote host server when they are communicating with each other:

  • On a PSF AFP Download Plus receiver, the system administrator specifies the port number of the server when starting the server. The commands to start the server (apshhrcd) are described in PSF for z/OS: AFP Download Plus.
  • On InfoPrint Manager for AIX®, the system administrator specifies the port number of the server when starting the server. The commands to start the InfoPrint Manager for AIX server are described in InfoPrint Manager for AIX: Procedures, G550-1066.
  • On InfoPrint Manager for Windows, the system administrator specifies the port number of the server when configuring the receiver. Information about configuring the MVS™ Download receiver on InfoPrint Manager for Windows is described in InfoPrint Manager for Windows: Procedures, G550-1073.
  • On Ricoh ProcessDirector, the system administrator specifies the port number of the server when configuring the receiver. Information about configuring the receiver on Ricoh ProcessDirector is described in the Ricoh Production Print Information Center at http://rpp.ricoh-usa.com/help/index.jsp.
  • On OnDemand, the system administrator specifies the port number of the server when starting the server. The commands to start the OnDemand server are described in IBM DB2 Content Manager OnDemand for Multiplatforms: Installation and Configuration Guide, SC18-9232.
