Execution Context:

Siebel Server Scripts are executed in Siebel Application Servers by Application Object Manager (AOM).
Siebel Browser Scripts are executed at Client Side by Client Browser (Internet Explorer)

Files:

Siebel Browser Scripts are converted in JS (Java Script) files and stored in PUBLIC\ENU directory.
No JS files are created for Server Scripts and they are executing using Siebel Scripting Engine either T or ST engine depending of Siebel version.

We can invoke Smart Script from a button using “RunCallScript” method of an Applet. For Example on Applet_PreInvokeMethod below given line of code will invoke Smart Script named “Test SS”

Full Compile: When you compile all the projects in a SRF file that is known as Full Compile.
