5215.0. "max # sockets ?" by SNOC02::63620::GRAHAM (Russell GRAHAM) Tue Feb 11 1997 19:02

I have a customer who is porting a client-server  application from
Alpha WIN NT 3.51 (server) to Alpha OpenVMS V7.1 and UCX V4.1

They have some questions about the capability of OVMS 7.1 in this area, namely:

- what is the maximum number of IP sockets per process on OVMS with UCX V4.1?
  (the customer is hoping for about 1000 sockets per process)

- what is the maximum number of IP sockets per OVMS node?

- can the printing facilites of UCX be used to print from an OVMS system to a
  HP4M+ laser printer via a WIN NT server.
  The printer is using a DLC/LLC connection to the NT server.

  If UCX can't help, any ideas on what software can be used to facilitate this?

Thanks,
Russell GRAHAM

Check out 'ucx show communication' it shows the maximum device sockets. If you set this to a really large value UCX seems to use this value modulo 65536. >- can the printing facilites of UCX be used to print from an OVMS system to a > HP4M+ laser printer via a WIN NT server. > The printer is using a DLC/LLC connection to the NT server.

Hear hear. This is a new one, usually customers are moving the other way
around....

1000 should be no problem. The maximum is usually limited by process quota
(fillm) or system quota (channelcnt).

>- what is the maximum number of IP sockets per OVMS node?

This seems to be 64K. Check out 'ucx show communication' it shows the
maximum device sockets. If you set this to a really large value UCX seems
to use this value modulo 65536.

I have used UCX outbound LPD succesfully to a NT server system.

Hope this helps,
