Setting the LATCH Environment Variable

---

The LATCH environment variable controls the number of unnamed synchronization objects allocated per Siebel Server.

To set the LATCH environment variable

Add the environment variable SIEBEL_OSD_MAXLIMITS to the profile of the administrator running the Web server and set it to 1, using one of the following methods:

For C shells:

setenv SIEBEL_OSD_MAXLIMITS 1

For Korn shells or Bourne shells:

SIEBEL_OSD_MAXLIMITS=1;export SIEBEL_OSD_MAXLIMITS

Optional. If more than 500 concurrent users will be using a single Siebel Server, set the Latch environment variables to manage these higher user loads.

NOTE:  Before changing this variable, stop the server using stop_server, and delete the $SIEBEL_ROOT/sys osdf file if it still exists.

The environment variables and values to be calculated are as follows:

SIEBEL_OSD_NLATCH = 7 * MaxTasks + 1000

SIEBEL_OSD_LATCH = 1.2 * MaxTasks
