Issue/Introduction

Executing CA MIM in two environments...production and non-production.

Running both MII and MIC in the same address space

The following commands are not working in the non-production environment. Notice the MIM3039W message:

• F MIM,D G,F000,1
  MIM3039W No linkage defined which can service command - suppressed  

• F MIM,D LINK ALL
  MIM3039W No linkage defined which can service command - suppressed

 

However, this same commands work in production environment:

F MIM,D G,F000,1

Notice that the following DISPLAY commands work in both production and non-production environments:

What could be the cause of the inconsistent behavior of these commands?

Seems as though there is a problem with the 'D'-display commands in the non-production environments.
 

Environment

Release : 12.5
Component : MIC

Cause

Check if there is a system defined on the DEFSYS statement with a sysname of 'D' in this non-prod MIMplex.

DEFSYS (C,C1,BSYS,INITIAL=FREED),
       (D,D1,DSYS,INITIAL=FREED),
       (E,E1,ESYS,INITIAL=FREED) 

As the MIM address space is also running the Multi-image Console facility, when the command 'D LINK ALL' or 'D G,F000,1' is issued, the command processor interprets the 'D' as a system name, which is then processed as a cross system command.

However, there is no link defined for this cross system command, which results in the MIM3039W message.

Resolution

The recommendation is to issue the command as 'DI LINK ALL' or spell DISPLAY completely.
