What is the database trigger environment user exit program?

The database trigger environment user exit program is how the generated DB Trigger program knows which LANSA system, partition, languages and date source the LANSA environment is to execute in. The database trigger environment user exit program is called DCTRGENVUE and must exist somewhere in the library list of any job that does I/O in any way to a table that has DB Triggers enabled.

The generated DB Trigger program will receive these parameters from the user exit program:

Description Type Length Usage LANSA Program Library Name *CHAR 10 Must be set. Partition *CHAR 3 Must be set Language *CHAR 4 May be blank for a non-multilingual partition, otherwise must be set Date format source *CHAR 1 Must be set to S or J. Refer to the LANSA command parameters.
