1. If the process is driven from Browser script (JavaScript), there is a SetTimer() function that allows repeating a process every few seconds. This could call a Business Service to do server client-side processing.

2. On Windows platforms only, it is possible to call the Windows API Sleep function directly. More information on Microsoft’s Knowledge Base (Article 231298: "HOWTO: Use SetWaitableTimer With Visual Basic")

3. Writing a dynamic linked library (DLL for Windows or so for Unix). This dynamic object can be written in any language. The VB language offers the delay function and/or timer functions, but it is only available on Windows platform. For Unix platform, the most common language is C.
 Solution implemented DLL on Window platform / on Unix platform:
 
For compiling the so file on Solaris, the customer has used the Doc ID 476274.1: Calling a shared library from eScript available on SupportWeb, but has added the following flags:
-static-libgcc

Full line for the link step was:

gcc libtest.o -static-libgcc -shared -o libtest.so

Generic eScript code for using on both platforms (Windows and Unix):
