Problem:

Is there a way to disable the Data Connect option on the mainframe?

Resolution:

To prevent an address space create, just remove the Data Connect definition from the SERVERS configuration, as shown below:

  Viz no ASGROUP=MFAS
 

*--------------------------------------------------------- 
* Application Server address space definitions 
*--------------------------------------------------------- 
* 
* Mainframe Access Server (Data Connect) address space 
* 
<ASGROUP=MFAS> 
ASPROC=XDBDC31 
ASJOB=* 
ASSERVER=MFDSTART 
ASMINIMUM=1 
ASMAXIMUM=1 
ASGROUPID=0 
<END>

This is also how you let multiple MFA regions share a single Data Connect.
