Set up the applicable cache paths under Templates Universal Preferences in the System Administrator application. If you have more than one database, set up separate path locations for caching the template files for each database. Preference Description Template Cache Path Enter the directory path to be used to store template files that are cached. Note: You can designate the directory to be used to store cached files in your ngconfig.ini file instead of the Template Cache Path. If you choose that option, do not enter this preference.

CAUTION: You must enter this path to run the Template Cache Generator. If this path is missing, the cache file is created in the Template Cache Path.

Accessing the Most Recent Cache File
When a user accesses a template, the system compares the time stamp of the local cache file to the time stamp of the template in the database. If the files are not in sync, the system compares the time stamp of the local cache file to the time stamp in the shared cache directory. If the local cache file is older than the server cache file, the server cache file is written to the local cache directory. If the server cache file is older than the local cache file, the local cache file is written to the local cache directory and pushed up to the shared cache directory. The following diagram depicts this template caching process. Parent topic: Template Caches

Cache Multiple Templates
You can cache all templates or only templates with out-of-date time stamps. You can run the Template Cache Generator from Template Editor or from a standalone executable file.

The NextGen Template Cache Generator window opens. The Only out of date templates check box is selected by default. A template is out-of-date if the cache time stamp for the template .ngt_file and the cache time stamp in the template database table do not match. To cache all templates regardless of the cache time stamp, clear the check box. Select Cache Templates. The window displays the name of each template being checked and cached. It shows a progress bar and how many of the total number of templates have been cached. To stop caching the remaining templates, select Cancel. The TemplateCacheGenerator window opens.

Cache all templates when there is a new Template Editor version or patch or NextGen® Enterprise EHR upgrade. You can select options in Template Editor to do the following: Cache an individual template. Cache all templates or only templates with cache time stamps that are not current.
