Re: SPAM: How to suppress some informational VTAM messages ?



Pat,

Everytime I have implemented Netview including 1.0 thru
the latest greatest, we used MPF to either pass or suppress
Messages. Netview's message automation table can also do this
If you pass all messages through MPF.

Regards,
Scott

The NetView "suppression" is actually a completely different
technique. If you define NetView as VTAM's "primary programmed
operator" VTAM passes its unsolicited messages to the PPO ACB
and doesn't issue a WTO at all. That means that MPF doesn't get
chance to play at all (yet). NetView can then decide to WTO the
messages. If NetView WTOs them, _then_ MPF gets in the act.

That word "unsolicited" is pretty important, though. Any VTAM
activation message relating to resources in VTAMs configuration
list - ATCCONxx - is considered solicited. VTAM WTO's those so
MPF can supress them. (

BTW, Solicited VTAM messages are supposed to be command
responses sent to the console issuing the command. I don't
know what that means in this case. The console issuing the
START NET? Consoles with AUTH=MASTER? Consoles with the
network routecode (8, I think)? Whatever, they go where not
wanted.

Another option available in NetView V5.1 (or maybe it was 5.2)
is the Message Revision Table where many MPF-ish actions (and
several not so MPF-ish actions) are available in NetView's SSI.
