Turning on the 4GT RAM Tuning Feature

You can expand the per-process address limit from 2 GB to 3 GB. This setting reduces the amount of physical RAM available to the operating system from 2 GB to 1 GB. The difference (1 GB) is allocated to your applications. This feature is referred to as 4GT RAM tuning. For information about how to configure this setting, see Microsoft's documentation.

Note: Each Siebel process (Siebel Application Object Manager) cannot use more than 2 GB of RAM.
