JR56299: Search cache invalidations are not propagated to production server

APAR status

• Closed as program error.

Error description

• For environments in which the search index is created in
  non-production, the cache invalidations that are
  fired by UpdateSearchIndex do not make it to the production
  servers.
  

Local fix

• Clients are forced to created their own custom trigger scripts.
  

Problem summary

• USERS AFFECTED:
  WebSphere Commerce Version 7 Feature Pack 8.
  
  PROBLEM ABSTRACT:
  Search cache invalidations are not propagated to production
  server
  
  BUSINESS IMPACT:
  Production JSP cache is not invalidated.
  
  RECOMMENDATION:
  

Problem conclusion

• A new scheduler command, InvalidateSearchCacheCmd, is added to
  be run on the repeater so that it can determine whether cache
  invalidation entries need to be generated based on the current
  state of the indexing server.
  
  This command checks entries by using the following mechanism:
  1. Queries the CACHEIVL database table to determine the most
  recent search-related invalidations
  2. Once the last invalidation time is determined, it turns to
  the indexing server and requests for a list of IDs that were
  updated since this given last invalidation time
  3. This command then takes the list of IDs (from both Catalog
  Entry and Catalog Group index) and generates the corresponding
  cache invalidation tasks based on the pre-configured cache
  invalidation templates in the wc-component.xml file
  4. The invalidation tasks are then inserted into the CACHEIVL
  table
  5. When DynaCacheInvalidation scheduler task starts at the next
  scheduled time interval, these CACHEIVL entries are processed
  and causes the respective dependent cache fragments to be
  invalidated.
  

Temporary fix
