Problem conclusion


    

  • The logical cache
com.ibm.commerce.catalog.facade.server.services.dataaccess.bom.m
ediator.util.FacetHelper.attr has been updated to provide
fine-grained caching.
 A cache entry is now made for each facetable attribute instead
of caching all in one single cache entry. The cache keys
considers attrdictsrchconf.SRCHFIELDNAME.

 By default, entries are cached in this distributed map:
services/cache/WCSearchNavigationDistributedMapCache. You might
need to re-tune the maximum cache size which by default is
 set to 1,000.

 JR50052 should be applied together with this iFix.
