ObserverReconnect

The ObserverReconnect configuration property specifies how often the observer establishes a new connection to the primary database.

Category	Description

Datatype	Integer
Property Type	Configurable
Scope	Configuration
Valid Role	Primary and standby
Valid value	Integral number of seconds. Must be greater than, or equal to, 0.

When this property is set to the default value of 0, the observer creates and maintains a connection to the primary database, but it does not periodically create a new connection to the primary database. While this eliminates the processing overhead associated with periodically establishing a new observer connection to the primary database, it also prevents the observer from detecting that it is not possible to create new connections to the primary database. Note that logging in and out of the database is a resource-intensive operation. Given that, Oracle recommends that this property be set so the value specified is small enough to allow timely detection of faults at the primary database, but large enough to limit the impact of logging in to and out of the primary database.
