APAR status

• Closed as program error.

Error description

• Portal is configured in multi servants mode. Cache replication
  is enabled in order to copy cache information on each servant.
  When a user logs in, the User Registry gets called and a cache
  entry is created. This cache entry is then
  replicated on all other servants through the control region
  that causes a performance overhead.
  

Local fix

Problem summary

• Portal is configured in multi servants mode. Cache replication
  is enabled in order to copy cache information on each servant.
  When a user logs in, the User Registry gets called and a cache
  entry is created. This cache entry is then replicated on all
  other servants through the control region that causes a
  performance overhead.
  

Problem conclusion

• Reduce cache replications by canalizing cache clearance and
  cache invalidations through an authorized access.
  
  This fix introduces a new setting for CacheManagerService
  that allows to enable
  cacheglobal.enableAuthorizedInvalidation = true. The default
  value is false resulting in an unchanged behaviour.
