PM02456: IMPROVE PERFORMANCE OF WCM API METHODS THAT RETRIEVE PARENT IDS

APAR status

• Closed as program error.

Error description

• The following WCM API methods that retrieve parent ids are slow
  when the code retrieves the parent from the strategy cache
   (after first failing to find a match in the absolute path
   cache) as the parent is unnecessarily cloned out of the cache:
     Content.getDirectParent
     Content.getParentId
     Category.getParentId
     Category.getParent
     SiteArea.getParentId
     SiteArea.getParent
     SiteArea.hasDirectContent
     SiteArea.hasSiteArea
     Site.hasSiteArea
  

Local fix
