In general, a separate virtual machine is required for each Entire Net-Work node.
Note:
IUCV is not supported on the z/OS platform.
To insure that enough IUCV connections can be made for Entire Net-Work, the MAXCONN parameter of the OPTION statement may need to be coded in the CP directory. The MAXCONN value for each virtual machine in the network must be set high enough to:
to allow one path for every LINK statement for the IUCV line driver; and
to accommodate all other products using IUCV communications or services that may be installed.
The default value is 4. If no more than 4 virtual machines exist in the network and no other products using IUCV are installed, the MAXCONN parameter need not be coded.
The MAXCONN parameter can be added to the other parameter in the OPTION statement as follows:
OPTION parm1 parm2 ... MAXCONN 10 ... parmn
