Is MIM using extended (EMCS) or subsystem consoles?

Products

• MIM Message Sharing (MIC)

Issue/Introduction

The customer wants to know if they're using extended consoles or subsystem consoles in MIM Message sharing. 

Environment

Release : 12.5

Component : MIC

Resolution

The GCMF feature of MIC determines console allocation in the GCMINIT statement.

By default, EMCS consoles are used. Parameter EXTCON=NONE can be defined in the statement to use subsystem consoles instead.


The EXTCON parameter is optional, with the following values:
EXTCON

     (Optional) Specifies how GCMF should allocate extended target consoles for the dynamic target console pool.

     The EXTCON parameter has the following options:

 

• NONE

   

  This indicates that GCMF is not to use MCS extended consoles for the dynamic target console pool. GCMF allocates subsystem consoles for the dynamic target console pool instead. CA does not recommend this option, but advises that you use MCS extended consoles for the dynamic target console pool.
•  
• PREFIX

   

  This value defines a one- to three-character prefix used in generating extended target console names. The first character must be alphabetic or national. The remaining characters can be alphabetic, national, or numeric.

   

  The prefix will be used as the first one to three characters of the extended target console name in the format

  pppssnnn

  , where

  ppp

  is the first one to three characters in the console name,

  ss

  is the system alias or system index number (depending on whether a DEFSYS appears for this system) and the remaining characters

  (nnn/nnnn/nnnnn)

  of the extended target console name will be a numeric value, in ascending sequence, generated by GCMF, for example, GCMAA000.

   

  Default:

  PREFIX=GCM
