Prefetching is triggered whenever BMC Remedy Mid Tier is restarted, or when the cache is flushed. Prefetching includes these processes:
- Forms with active links and menus are preloaded into the system's memory.
- If a prefetchConfig.xml file exists (from a previous release of BMC Remedy AR System), all of the forms and views specified in that file are preloaded.
- Views are preloaded according to usage statistics gathered by the BMC Remedy Mid Tier server.
The first prefetching process can be enabled by checking the Enable Preload option from the General Settings page of the BMC Remedy Mid Tier Configuration Tool.

Specifying multiple threads for prefetching
You can specify the number of prefetch threads in the config.properties file by editing the arsystem.max_number_of_pretch_threads flag.
User and group permissions for prefetching
For example, suppose you have two groups, Group A and Group B, and two users, User 1 and User 2. Group A includes both users; Group B includes only User 2. User 1 has a permission set for Groups A and B; User 2 has a permission set for Group B only.
Prefetching is made easier if users are assigned a set of permission groups that perform the same function.
