In the process of adding additional NODE statements to an existing CCI parameter file (CCIPARMS). 

What is the recommended process to apply these changes? Is just recycling ENF(considering other products rely on ENF) enough, or is an IPL of the system suggested?

A fully operational CCI environment already exists where a number of systems are currently connected. New systems are being added and corresponding NODE and CONNECT statements have been defined to the CCI parameter file.


  • Mainframe z/OS systems
  • Any supported release of CA Common Services


An IPL is certainly not necessary for this activity. It is also not necessary to recycle ENF to add additional CCI NODES.

New CCI NODES can be added dynamically by issuing the NODE statement at the console.

For example, the command CCI NODE(protocol,netparm,retry,sysid,maxru,start/stop,netparm2) can be issued as a console command. Therefore, whatever new NODE statements you added (or plan to add) to the CCI parameter file, just issue the CCI console command to have it dynamically defined. This can also be done with the CONNECT statement....CCI CONNECT(sysid)

To make changes permanent, remember to define any new statements to the CCI parms so that they are picked up next time ENF is recycled.

Examples: As a console command


Examples: As defined in CCIPARM member (ENFPARMS DD stmt)
