Issue/Introduction

You currently have a new system (SYSA) setup and want it to use OPSMVS MSF, relying on CCI connection, to connect to other systems B/C/D which are already using CCI.

Is there a way to update systems B/C/D CCIPARMS file with the new systems (SYSA) CCI remote information and make it effective without restarting the ENF and CCISSLGW tasks, which will interrupt existing MSF connections?

Resolution

Yes, you can dynamically add new remote systems, but will still need to update CCIPARMS to make the changes permanent.

Being that you already have a system running ENF/CCI with connections to remote systems, you can add connectivity to new systems by issuing console commands to add new NODE and CONNECT statements. For example:

CCI NODE(protocol,...)
CCI CONNECT(sysid)

The syntax is the same as what will be needed to define the new system in the CCIPARMS member.

The CCIPARMS member on systems B/C/D must be updated to add SYSA so that the new system is picked up the next time ENF is restarted.

Refer to the documentation for details on the NODE and CONNECT control options.
