Registration is an operation through which Oracle stores information about an agent in the data dictionary. Agents do not have to be registered. If an agent is not registered, Oracle stores information about the agent in memory instead of in the data dictionary. When a session involving an agent terminates, this information ceases to be available.
Self-registration is an operation in which a database administrator sets an initialization parameter that lets the agent automatically upload information into the data dictionary. Self-registration occurs when the HS_AUTOREGISTER initialization parameter is set to TRUE (default).
Note:
HS_AUTOREGISTER is an Oracle initialization parameter that you set in the init.ora file; it is not a Heterogeneous Services initialization parameter that is set in the gateway initialization file.
