Price rule object cache overview
Business object caching eliminates querying of price rule database tables when setting prices on the storefront for a customer. By managing the memory allocated to the cache you can fine-tune price rule performance.
PriceRuleCache (PR_Cache)
The
PriceRuleCache object cache instance is a location where a distributed
map cache (PR_Cache) stores data pertaining to a
price rule business object.
- Price rule business objects
- Price equation business objects
- Price constant business objects
The business object mediators to create, update or delete price rule, price equation or price constant, will maintain the appropriate data in the business object cache.
- PriceRuleGetContractUnitPriceCmdImpl.class
- PriceRuleEngine.class
Clearing the cache
If you need to clear
the PR_Cache, run the scheduler job InvalidatePriceRuleCache
using the Administration Console. If the price rule information in
the database is updated through SQL, massload, or stageprop, then
you should clear all the cached information. For information on how
to run a scheduler job, see Scheduling a site-level job.
Refreshing the store registry
If you create a new extended site store, refresh the Stores registry after the store is created successfully. For information on how to refresh a registry, see Updating registry components.
