• COMMON SERVICES FOR Z/OS

Issue/Introduction

Is it possible to dynamically disable the VTAM connections,  add new TCPIPGW NODES, and dynamically connect those new TCPIPGW NODES - WITHOUT an IPL?

You are intending to stage the corrected CCCI**** members for the next IPL.

Environment

Release : 15.0
Component : CAICCI MVS

Cause

New SYSPLEXES were added to the environment and defined incorrectly.  Want to use CCI to propagate the passwords to the new environment.

Resolution

You can make the changes/corrections dynamically through console commands with no recycle or change the CCI parms and recycle - will be picked up at the next IPL. 

    Two methods to accomplish this:

1. First use CCI Control Options sent to the console to remove unwanted definitions and add corrections. Does not require a recycle of CCI.
   
   
   • To remove:
     • Use the VARY and REMOVE commands to VARY them inactive then REMOVE them  
   • To add:  
     • Use the NODE and CONNECT commands to define the NODES and CONNECT them to the new Sysplexes
2. The second method is to make the changes to the CCI parms themselves and recycle CCI
