Issue/Introduction

How can ACF2/IMS users sign on to an IMS region multiple times with the same ACF2 logonid?

 

Environment

Release:
Component: ACF2MS

Resolution

ACF2/IMS supports multiple signons to an IMS region through the use of the ACF2/IMS interface "ENQNAME" control option.

The ACF2/IMS interface controls the simultaneous use of a single logonid to sign on to multiple systems through the use of the ENQNAME option in the ACF2/IMS SIGNON record. It does not prevent a user from signing on to multiple control regions in different lpars (IMSPLEX). To let a user signon to the IMS control region concurrently from more than one terminal, you must turn off the ACF2/IMS enqueue function. To turn off the enqueue function, do not specify an ENQNAME value, instead specify NA (not applicable) for the ENQNAME value.

To change the enqueue parameter in the ACF2/IMS interface, enter the following subcommand from the CONTROL IMS setting of the ACF command:

ACF
SET CONTROL(IMS)
CHANGE DIVISION(musid|jobname) SIGNON ENQNAME(SYSIKJUA|queuename|NA)

 

Additional Information

Details on the IMS SIGNON record can be found in the ACF2 IMS Support Guide, Chapter 6: System Control Options, section "Interface Control Options", sub-section "Multiple Sign-on Control (ENQNAME)".
