INHIBIT-LOGONS

Prevents all users, except the database owner (depending on option) and, on a UNIX system, the super-user, from logging on to the database.

Syntax

INHIBIT-LOGONS {(option}

Options

A prevents all users, including the database owner, from logging on. The UNIX super-user can still log on.

Restriction

SYSMAN and SYSPROG accounts only.

Comments

The database owner is the system user-id under which the database was created.

Caution

If general users are allowed to logon under the database owner's system user-id, INHIBIT-LOGONS will not be effective, unless you use the A option.

If INHIBIT-LOGONS (A is executed, the only way the inhibit condition can be reversed is either by the super-user logging on to the database and using ENABLE-LOGONS, or by the super-user using the unlockdbase command from UNIX.

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. INHIBIT-LOGONS sets the read permissions to owner only or, with the A option, to no access permissions.

The lockdbase command performs the same function from the host system environment.
