Specifies when VTAM should end its SSCP-LU and
SSCP-PU sessions and, when DISCNT=YES, whether to indicate final-use
status in the DACTPU request unit when it deactivates a physical unit.
- DISCNT=(NO)
- If you code NO or use the default, VTAM terminates the SSCP-LU and SSCP-PU sessions when certain conditions are met. See z/OS Communications Server: SNA Network Implementation Guide for a discussion about those conditions.
- DISCNT=(YES)
- If you code YES, VTAM automatically ends the SSCP-LU and SSCP-PU sessions when the last LU-LU session is ended.
- DISCNT=(YES,F)
- DISCNT=(YES,NF)
- specifies whether VTAM indicates
a final-use status in the DACTPU request unit when it deactivates
a physical unit as a result of DISCNT=YES. This value does not apply
when DISCNT=NO, nor does it have any effect on the VARY INACT command.
If you code F or use the default, final-use status is indicated and the connection can be ended. If you code NF, not-final-use status is indicated and the connection should not be ended.
Each device has its own requirements regarding final-use status. To determine whether to code F or NF for a given device, consult the appropriate installation publication for the device.
