Specifies whether HPR can be used although it may cause
session data to travel through an NCP twice. If HPR is used, session
data may pass through the NCP as HPR data on the RTP connection AND
also as non-HPR data.
- HPRNCPBF=NO
- Specifies HPR will not be used if session data might travel through an NCP twice.
- HPRNCPBF=YES
- Specifies that HPR can be used although it may cause session data
to travel through an NCP twice.
When coding HPRNCPBF=YES, in general your considerations are possible decrease in network performance but better session availability.
You can change the value of HPRNCPBF with the MODIFY VTAMOPTS command while VTAM® is running. If you change the value from YES to NO, no new RTP connections are activated that would cause session data to go through an NCP twice, but existing such RTP connections may in some cases be used.
