DECnet over TCP/IP

[Kjell Carlsson]

Hi
I have a number of VMS-systems using DECnet over TCP/IP. Host names / IP-addresses are delivered by a central DNS. But when changing the IP-address of a node the other VMS-nodes don't reach the changed node without a manual DECnet Plus cache flush. Is there some way to overcome this?

Best regards

Sorry Karl. I don't understand your answer.

I was more joking than giving a real help,
if you change IP adresses often, just flush the
cache every N hours/minutes/days...

Hello,

in the decnet configuration (@sys$manager:net$configure advanced) you can set the
Naming cache timeout value
Normally this value is 30 days. Perhaps it helps you if you decrease this value (but I've never tried, normally I flush the cache).

Kind regards,

Kirsten

Kjell,

'cron' is a utility from the Unix world that is used to run job at regular intervals. That avoids the requirement for self-submitting batch jobs. You can read some more background information at:

http://www.unixgeeks.org/security/newbie/unix/cron-1.html

Over the years several people have done ports / reimplementations of 'cron' for VMS.

Hi,

You can make command procedure to flush the cache and can run it everyday as batch job or using polycenter scheduler . On our systems we are doing the same...

Thanks & regards,
