Error description

• Introduce FirstLevelCacheing for
  cacheinstance.com.ibm.wps.pe.portletentity to prevent high DRS
  access load.
  
  This APAR introduces an additional caching layer ontop of DRS
  cacheinstance com.ibm.wps.pe.portletentity. This APAR includes
  the changes from PM14128.
  
  The default size of this first level cache is set to
   cacheinstance.com.ibm.wps.pe.portletentity
  .firstLevelCacheSize=5000
  The specific value can be modified through
   Resource Environment Providers -> WP CacheManagerService ->
  custom properties
  and should be less than the configured size for the DRS cache
  (cacheinstance.com.ibm.wps.pe.portletentity.size / default is
  10000).
