Training "Question of the Week", March 17th, 2008

Updated on September 10, 2021

I know that "Rules Assembly" is an expensive process. Is there any way to prime the rules cache with rules so users don’t have to go through this?

Answer by Bob Ellis
Although some have tried to prime the cache using external tools, this is not a recommended practice. Beginning with PRPC V5.3, cache priming is enabled by default. This works by taking a snapshot of the cache and saving those rules. When the application server is restarted, the cache is primed with those rules that were saved during the snapshot, significantly reducing rules assembly (also called "First Use Assembly") times.

Rule caches are discussed in the System Administration course. You can also get more information about the rule assembly cache in the on-line and in-product help topic "Working with the rules assembly cache".
