This document was previously published as Siebel SR 38-2978023726.
we want to set the environment parameter SIEBEL_OSD_LATCH. I found on the Support Search two documents:
1.Siebel Server Installation Guide for UNIX > Installing the Siebel Server > Post-Installation Task for Siebel Server
Here is the next formula for calculation:
The environment variables and values to be calculated are as follows:
SIEBEL_OSD_NLATCH = 7 * MaxTasks + 1000
SIEBEL_OSD_LATCH = 1.2 * MaxTasks
The second document is in:
Performance Tuning Guide > Tuning Siebel Workflow for Performance > Tuning Workflow Process Manager for Performance >
And here is next formula for calculation:
It is very important that you make sure to keep the server running under 80% CPU utilization. If there are any changes on MaxTasks, change SIEBEL_OSD_LATCH and SIEBEL_OSD_NLATCH based on the following operations:
SIEBEL_OSD_LATCH = 2 * (Accumulated MaxTasks of all components)
SIEBEL_OSD_NLATCH= 10 * (Accumulated MaxTasks of all components)
And we need the precision information about the setting of this parameter, which formula is the best?
