CAICCI Connections

To participate in cross platform scheduling, all machines must have CAICCI installed, active, and connected to the machines involved.

For non z/OS communications, CAICCI connections are defined in the following files:

The format of the REMOTE control cards are:

REMOTE = ip address cciname blocksize [STARTUP] [PORT=nnnn] [RETRY=x]
ip address

Specifies the numerical TCP/IP address of the node or the hostname that can be resolved into a 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. A TCP/IP PING command on this value should be successful.

cciname

Specifies the name that CAICCI will use for this node. This value can be the same as the hostname, but it does not have to be. The name must match the CAICCI name defined at the remote node. For z/OS, the CAICCI name is defined by the SYSID parameter in the ENFPARMS.

STARTUP

If specified, indicates that the connection is attempted as soon as CAICCI starts. This is recommended.

PORT

Specifies the TCP/IP port number (nnnn) to use. The default on z/OS with CAICCI 2.1 is 1721 and can be changed on the PROTOCOL(TCPSSLGW…) statement. (The default port for non z/OS machines is 1721.).

RETRY

Specifies the time (x) to wait to reconnect if the connection attempt fails or is broken.

CAICCI must be recycled to pick up changes to the ccirmtd file. The ccirmtd file also contains the LOCAL statement, which identifies this machine in a CAICCI network. Example LOCAL statement:

LOCAL = BARNA03SRVR BARNA03XPS 32768 startup ALIAS=BARNA03W

An ALIAS keyword is required when the CAICCI name field, the second field on the LOCAL statement, is longer than 8 characters. Most CAICCI applications on the mainframe can only support 8-character CAICCI sysids (including cross platform scheduling). The ALIAS setting will be the 8-character name that the local machine is known as by z/OS CAICCI applications.
