When you open a server window for the first time, Migrator generates the following cache files in the Migrator directory on your hard drive:

• A server cache, where workflow support files are located.
• A database information cache for the server, which lists all the required AR System object information. This information is used by the list views for both the server windows and the form detail windows.
• A dependency file cache for the server, which is used to generate upward and downward dependency information.

You can specify the directory in which to store cache files. See Specifying-directories-to-store-migration-files.

Although initial caching takes time because Migrator copies all the objects from the server to your computer and builds the database, cache files ultimately save time and lessen the load on the server.

Refreshing and updating cached objects

To recache your computer after the initial caching, select View > Refresh (or press F5).

Whenever you reopen a server window, Migrator updates cache files, taking less time because only changed objects are cached. Migrator also updates the object type cache when you switch object types in the left pane of the server window. For example, when you go from Forms and click Filters, Migrator updates filters. When you go from Filters and click Forms, Migrator updates forms.

Migrator also updates the cache file during a migration. To view the changes in the cache after a migration, refresh your display by pressing F5.

You can turn automatic caching on or off. To do so, select Tools > Options, and then click General in the left pane to display the caching options (see Specifying-cache-settings-and-general-options).

Migrator provides an option to keep or delete the database and dependency files generated with .migrator files. See Specifying-cache-settings-and-general-options.

Space limitations on caching

During a cache process, Migrator warns you when less than 10 MB of space is available on your computer. When you see this warning, stop the caching process, create more hard drive space, and then cache again.
