Tuning Kernel Settings for HP-UX

This topic is part of "Tuning Siebel Business Applications for HP-UX".

Modify the HP-UX kernel parameters to values like those shown below (suggested guidelines). Use the HP-UX System Administration Manager (SAM) tool to make these changes.

Setting Permissions for the HP-UX Scheduler

This topic is part of "Tuning Siebel Business Applications for HP-UX".

Siebel Business Applications will have better performance on HP-UX if you make the following changes, which allow the Siebel Server to execute the HP-UX scheduler upon startup. You must have root privileges to make these changes.

To set permissions for the HP-UX scheduler

1. Add the following line to the /etc/privgroup file, creating it if necessary:

   -g RTSCHED
   

2. Save the file and exit.

3. Execute the following command:

   setprivgrp -f /etc/privgroup
   

4. Verify that global RTSCHED permissions are set by executing the following command:

   getprivgrp
   

   If the command is successful, then the system will respond:

   global privileges: RTSCHED
