AB 156 INFORMATION RELEASE
Tuning Networked Systems.
It has been found that our existing tuning formula are inadequate for network user systems with more than 32 users or more than 32 printers.
1. Users.
For each networked user logged into the Application there will be:-
- a pts process running.
- a initelnetd process running.
- for Charisma users a sh process running.
For processes not logged into the application there may be:-
- an intilnetd process
- a login process
This means that the total number of processes active at any one time may excess the maximum tuned course `fork failure' messages.
To prevent from occuring adopt the following for all the systems:-
(1) MAXUP - tune to be 200 + 2 x number of users.
(2) NPROC - tune to be 200 + 2 x number of users and 10%
2. Printers.
When printers are connected to terminal servers they require reverse telnet processes to make the logical connection from the link file to the MTS port.
Each of these processes require 1 autopush function. The default for SVR4 for the tuning parameter NAUTOPUSH is 32.
If more than 32 reverse telnet processes are to be created tune NAUTOPUSH to 2004.
