Server Caching and MDM Hub Console Locks

Server Caching and MDM Hub Console Locks

When no locks are in effect in the
Hub Console
, the
Hub Server
 caches metadata and other configuration settings for performance reasons. When a
Hub Console
 user acquires a write lock or exclusive lock, caching is disabled, the cache is emptied, and
Informatica MDM Hub
 retrieves this information from the database instead. When all locks are released, caching is enabled again.
When more than one
Hub Console
 uses the same
Operational Reference Store
, a write lock on a
Hub Server
 does not disable caching on the other Hub Servers.
