DECNET Phase V
I would like to increase NSP connections from 200 to 600.
We have 2GB of memory on the server.
For our information how much memory does each extra NSP allowed NSP connection require.
Of course each extra connection will allow extra process to be created that will require some type of resource.
The question is based on having the extra allowed connections but not using them.
Regards
Kevin Raven

Re: DECNET Phase V
To make this permenant then edit
SYS$MANAGER:NET$NSP_TRANSPORT_STARTUP.NCL
You are correct that using 600 connections will need more resources.
Purely Personal Opinion

Re: DECNET Phase V
When you increase NSP maximum connections from default of 200 to 600, you have to check the following as well.
1. Make sure "maximum receive buffers" = "maximum transport connections" X "maximum window"
2. Make sure "maximum remote nsaps" = "maximum transport connections" + 1
3. Memory required will be "maximum receive buffers" X "manual data link SDU size" of the routing circuit.
Hope it helps.
Thanks and regards.
Michael

Re: DECNET Phase V
adding to the above posting, when you edit SYS$STARTUP:NET$NSP_TRANSPORT_STARTUP.NCL file, make sure...
1. Maximum receive buffers value must be 8 times the value of the maximum transport connections
2. max window value must be greater than or equal to the number of maximum receive buffers divided by maximum transport connections.

Re: DECNET Phase V
You should/can use NET$CONFIGURE to change these values.
$@NET$CONFIGURE ADVANCED
Select option- [4] Configure Transports
It will display the current values and allow you to change them. Not checked, but I would expect it to perform some form of sanity checks on your values. Entering a ? at the prompt will give additional help, it sometimes gives useful detailed info.
Also, the .NCL scripts are checksum'd, net$configure will report warnings if they've been altered outside of net$configure.
It's up to you, but net$configure is there to guide you
Kind Regards
John.

Re: DECNET Phase V
1. you can ctrl_y out (no changes will be made) if you need to.
2. The current values for each question asked (on an already configured system) are presented in []
3. Once all questions are asked, it lists the new settings and gives you a final chance to accept or reject the changes made
Hope this helps
John.
