Issue/Introduction

I am getting an issue trying to submit a console command to the MUF. I am not sure what is wrong. It shows that the MUF is up and running in my system

F CA7TMUF,CLOSE 2
IEE341I CA7TMUF           NOT ACTIVE

Environment

CA Datacom/AD

CA Datacom/DB

Cause

The most common problems for a console command not working are:

1. The mufname is specified instead of the jobname
2. Security-related/users may not be authorized and/or have to consult with operations
3. Submitting a console command from a different LPAR where MUF resides
4. MUF may not be up (must be active)

Resolution

In this example, the reason this failed is because the modify CLOSE console command was issued against the MUFNAME/CXXNAME (CA7TMUF). 

In order for this to work, the console command has to be issued against the jobname

Submitting a console command uses the standard IBM MODIFY command. The syntax can be seen down below

The STATUS console command is one of many console commands that you can issue to the MUF.
An example of this and how MUF displays the console message in the MUFJESLG (issue a ? or L on MUF job and MUFJESLG will be first file) can be seen down below

Command line Input in SDSF or CA SYSVIEW:
