Parameters for Optional Interfaces for Separately Licensed Features › MSF Parameters › MSFNONVTAMONLY Parameter

MSFNONVTAMONLY Parameter

Determines whether MSF uses only non-VTAM based communication protocols.

To use MSF when VTAM is not active, set the value of MSFNONVTAMONLY to YES. If MSFNONVTAMONLY is set to NO, VTAM must be active to use MSF.

The MSFNONVTAMONLY parameter lets you either use non-VTAM MSF connections before VTAM has completely initialized or not use VTAM at all. In the first case, if you need such non-VTAM MSF connections, and also want to use VTAM MSF connections after VTAM has initialized, you can start CA OPS/MVS with the value of MSFNONVTAMONLY set to YES, and use a message rule to set the value of MSFNONVTAMONLY to NO and activate VTAM MSF connections after VTAM has initialized.

Default value

NO

This value indicates that VTAM must be active to use MSF.

Other possible values
