Release 10.1A: OpenEdge Getting Started:
New and Revised Features

Database trigger code startup parameter required

In Release 10.1A, 32-bit clients and 64-bit clients cannot share the same database trigger code. If you plan to provide two editions of your application—one for 32-bit platforms and one for 64-bit platforms—you must:

Compile a 32-bit edition and a 64-bit edition of your application code and make sure to place the editions in locations (directories) that are separate from each other.
Use the Trigger Location (-trig) startup parameter to specify the location of the appropriate database trigger code (32-bit vs. 64-bit) when you run each edition.
