A very simple database is created by drc and the commands dr_put_db, dr_append_db, dr_get_db can be used to manage the database. By using these commands, connection scripts can share information about each execution state (See section 3.4.1 "drc Execution States). For example, if each connection script keeps track of its execution status, (e.g. running), done, it is easy to judge which connection script is running or just has finished when an error occurs. It helps canceladd or cancelremove connection scripts run proper error handling procedures.
Each record of the database is a set of name=value pairs and a connection script identifier, e.g. iomp.
The user should not use this database as a permanent storage resource since it is initialized every time drc is executed.
Concurrent access to the same database is not allowed. In such a case, the commands unsuccessfully end with exit status 5.
