db_server process

Because client programs cannot access VOB databases directly, they must send database transaction requests to a db_server process when they must create, read, or modify VOB data or metadata.

Each db_server process services a single client at a time, but can operate on any number of VOBs. A client establishes a connection to a db_server with the help of the albd_server on the VOB host. If necessary, the albd_server starts a new db_server process to handle a request. The connection is broken when the client exits or becomes idle (stops requesting database transactions for an extended period). At that point, the db_server becomes available for use by another client. After a period of idleness, an unconnected db_server is terminated by its host’s albd_server process.
