dynamic_variables_file

Name

dynamic_variables_file_only — dynamically update configuration directives from files only

VALUE

0 | 1

DEFAULT

DESCRIPTION

If this pragma is set, it prevents opening of Interchange databases in search for dynamic content of the directives, so that only files are checked.

It only makes sense to use this in combination with the dynamic_variables pragma, and DirConfig and VariableDatabase directives, so check their reference pages for more information.

EXAMPLES

Example: Enable dynamic_variables_file_only pragma catalog-wide

Put the following in your catalog.cfg:

Pragma dynamic_variables
Pragma dynamic_variables_file_only
