WEBSPHERE PORTAL V6.1 TUNING GUIDE
R E G I S T R Y S E R V I C E
WebSphere Portal maintains information about many resource types in its databases. Some
of these resources are replicated into memory for faster access; this is provided by the
registry service. This replicated information will be periodically reloaded from the database,
thus picking up any changes which may have been made on a peer node in a clustered
environment.
The registry service allows configuring a reload time, in seconds, for each type of data which
it is managing. In a production environment, we expect this type of information changes very
infrequently, so we used very long reload times for the registry service. A full list of the types
of information managed by the registry service is in table 4.
