In the UNIX environment, disabling of logon is achieved by maintaining a
LOCK.FILE file in the top UNIX directory containing the database. A user must
have UNIX read permission on this file to be able to log in.
In the Windows environment, disabling of logon is achieved by setting a Locked value to zero, in the database registry entry. The lock is maintained across a system re-boot or shut-down of the Reality services.
The lockdbase command performs the same function from the host system environment.
