If the IMS™ subsystem is part of a Remote Site Recovery (RSR) complex and the activity performed by ZDT/IMS functions running in DLI mode is to be tracked by RSR, specify the one to four-character Transport Manager Instance (TMI) name that the functions are to use.

This parameter is optional. If it is not specified on the HFM1POPI macro statement, ZDT/IMS uses either the value specified on the HFM1POPD macro statement (if specified on that statement), or a null value (otherwise).

When the activity is tracked by RSR and a null value is passed to the IMS region controller, IMS uses:
  • The value specified for the TMINAME parameter on the IMSCTRL macro statement (if specified on that statement), or blanks (otherwise).

If you do not want the user to override the value you specify for this parameter, set URSR=N.
