Product

• Brisque 4.x
• Brisque serve 4

Platform

All Brisque platforms

Operating system

IBM AIX 4.3.3

Symptoms

Paging activity is high, thus slowing down the system.

Solution

1. Using vi, open the $SCI_SCRIPTS/start.ScitexServers file, and remove the # sign that appears at the beginning of the following line:
   su sciroot -c "/usr/samples/kernel/vmtune -p 10 -P 30 1>>&$logfile"
2. Reboot the computer.
3. To verify that the change was accepted, type:
   /usr/samples/kernel/vmtune

The system should respond with the following:

vmtune: current values:
-p -P -r -R -f -F -N -W
