Version: Oracle Portal 3.0.6.6.5 or later Deprecated: Oracle9iAS Portal 9.0.2
Parameters:
p_provider_ id | The ID of the provider from which a node record is returned. Datatype: in integer
Returns: This function returns a node_record containing details of the specified node. Exceptions: If the node for the specified provider ID is not found, a NODE_NOT_FOUND_EXCEPTION is raised. If the specified provider ID is not found, a PROVIDER_NOT_FOUND_EXCEPTION is raised. If an error occurs when retrieving the provider record, a PROVIDER_RETRIEVAL_EXCEPTION is raised. If an error occurs when retrieving the node record, a NODE_RETRIEVAL_EXCEPTION is raised. If an error occurs when retrieving the database link information, a NODE_DB_LINK_EXCEPTION is raised. Note: This and other provider node APIs add error messages to the error stack before they raise exceptions. This allows users to interrogate the error stack if a problem occurs. Example: l_node_info := wwpro_api_node_registry.get_node ( p_provider_id => 5629 );

Notes
Distributed providers are providers on remote nodes. A database link is an object stored in the local database that identifies a remote database, a communication path to the remote database, and, optionally, a username and password for it. Once defined, the database link is used to perform queries on tables in the remote database.
