tcpip Sockets et al (OpenVMS)

[Richard Witkopp]

I've heard of something similar with a Point of Sale system, but they used a
VMS mailbox instead. This is a facility created in memory that's pretty
fast. The P'hoose interface to it is efficient, so you have no worries of
P'hoose interacting with the C program. They simply had the external system
deposit transactions into the mailbox and VMS provided the bridge.

 

I think it was presented at one of the annual Cognoid meetings back when
they used to have them.

Good Morning PH listers:

 

Seeking some knowledge with respect to the capabilities and complexities of
tcpip communications: Alpha OpenVMS Powerhouse 7.10G Quick calling a 'C'
program which opens a socket connection port #, via tcpip and send/receives
data from an external system. What a mouthful that was!

 

Basically we have an application which works per the above and I'm just
trying to see what the capabilities of replicating something like it but on
a much larger scale - perhaps thousands of transactions a day versus the
number of about the present (say) 30 a week....Contention and any queuing
logic we have to develop are my main concerns.

 

Any response gratefully acknowledged.

 

TIA
