z/OS Connections

A TCP/IP Gateway PROTOCOL statement is required for any CAICCI cross-platform scheduling communication. This is required even if the individual node definitions are defined on the non-z/OS platform.

If you need a z/OS system to initiate a connection to a distributed system, you must add one NODE and CONNECT statement as follows to your z/OS CAICCI parameters for each distributed system that you want CAICCI to initiate a connection with.

NODE(TCPSSLGW,ip-address:port,retry,cciname)
CONNECT(cciname)

Note: Keep in mind that the default is for distributed systems to initiate CAICCI connections with a z/OS system. This tends to work better because smaller UNIX and Windows Server systems tend to have more outages. However, you can set it up so that z/OS also initiates connections. If the z/OS system is IPLed or ENF or CAICCI is recycled, a connection to a distributed machine would be reestablished slightly faster when initiated by the z/OS system.

Here are the NODE and CONNECT statement descriptions:

TCPIPGW or TCPSSLGW

Identifies what protocol to use for the connection. This value is required.

ip-address

Specifies the numerical TCP/IP address of the node or the hostname that can be resolved to the TCP/IP address. You can specify an IP address in either IPV4 format (dotted decimal notation: "ddd.ddd.ddd.ddd") or IPV6 format ("xx:xx:xx:xx:xx:xx:xx:xx") in release r12 and later

port

Specifies the TCP/IP port number to use at the specified node. If omitted, the port number for the TCPIPGW or TCPSSLGW protocol on the local machine is used.

retry

Specifies the number of minutes to wait between attempts to establish or reestablish the connection.

Retry time must be specified from 1 to 59 minutes.

cciname

Specifies the name that CAICCI will use for this node. cciname is also referred to as the cci sysid.
