FirstBase RDBMS Overview]
The lock manager is presented as a menu of selectable items. These selections include Query, Clear, Set and Auto Query. The Query selection will provide a single snapshot of all locks currently set in fblockd. Each file that has active locks will be listed. Under each file, an indented list of locks is displayed. The lock information includes hostname, process id (pid), record number, lock start point and length, record number, and a timestamp.
The Clear selection produces a numbered list of locks. After one of the locks or files is chosen, a signal is sent to fblockd to clear the requested lock or set of locks.
The Set selection can be used to set a lock on an entire file or a particular record. A few notes: the lock file for a FirstBase database is the map file of the three files used for a database; a full path name must be used; record numbers (not byte locations) are used to assign a lock.
The Auto Query selection allows unattended queries to be automatically done every few seconds. The time between updates is selectable.
