Reading Command Data
Whenever command data is needed, such as to generate an output command to send on, this data is read from the database. This is the only time that data is read from the database, except at boot up, and is done purely as an optimisation to limit the amount of memory used by the daemon.
The storage of the information in the database has the additional advantages:
•
It provides the user with information on the progress of his commands, allowing him to browse the messages that have been received and persisted in this database.
•
It provides the administrator with an audit trail to determine if and where a problem has occurred.
•
It provides other modules of the base product with a store to deposit local administration information such as element claims. However, these commands are totally ignored by the daemon.
