SAM : Tuned Kernel Parameter Set

cch_1 — Mon, 20 Aug 2001 03:12:21 GMT

Any document about what special Kernel parameters are customised for each type of predefined System/Application. What is the reason/thinking behind in each Parameter Set?

The currently available choices are :-
CAE/ME/EE Engineering Workstation
General OLTP/DB client System
General OLTP/DB Monolithic System
General OLTP/DB Server System

Thanks ...

Hi,
I would say - Its a good start for tuning a server when you dont know (yet) what you need!
For example I would choose rdbms server tuning when installing a small box with oracle server, like that it pretunes all the semaphores values, openfiles and procs for you...
When you know you will be configuring a larger server with many oracle/sybase etc... and have many online users and batches running choose monolithic server...

There is a way to see what is being changed:
save your /stand/system -> /stand/system.sav

choose a config, then have a look at the system file generated and compare...

All the best

Victor

Hi,

The tuned parameter set are in /usr/sam/lib/kc/tuned. There are a bunch of .tun files there, if you want you can create your own set of parameters and save that file in that directory, depending on the first line you choose in your file, that will show up when you SAM to apply your parameter set.

-HTH
Ramesh
