This feature enable new Agent Preferred Connect Descriptor that allows a user to specify a custom connect string for an EM Agent to use to connect to a target database. This feature will provide the ability to override the default connect string used by the Agent that is derived from
the database host/port/SID, and will allow users to address the following database monitoring issues:

a.Users can specify a connect string that uses a Service Name when there is a need for monitoring the database using a Service Name instead of SID, such as when the USE_SID_AS_SERVICE parameter has been set in the database listener. (e.g., this setting is required by DB Service Firewall).
b.Users can specify a SCAN listener for RAC database monitoring.
c.In cases where the Agent can connect to the database only through a private (internal) hostname that is not resolvable from the OMS and which is different than the external hostname under which the database is discovered.This feature can be used to specify a connect string containing the private hostname or IP address that is resolvable from the Agent.
