4.4.3 Booting Without the User Authorization File
Ordinarily, the startup and login procedures provided by Compaq always work;
however, certain user interventions can cause them to fail. A very simple way to
lock yourself out of the system is to set passwords to login accounts and forget
them. In such an emergency, you can use the alternate user authorization file
rather than the standard user authorization file.
Note
You can use this method only to log in to the system from the console
terminal; you cannot use other terminal lines.
Setting the system parameter UAFALTERNATE defines the logical name
SYSUAF to refer to the file SYS$SYSTEM:SYSUAFALT.DAT. If this file is
found during a normal login, the system uses it to validate the account and
prompts you for the user name and password.
If it cannot find this file, the system assumes that the UAF is corrupt and accepts
any user name and any two passwords to log you in to the system from the
system console. Logins are prohibited from all other terminal lines.
When you perform this procedure, the system assigns the following values to your
user account:
Field Value
Name User name
UIC [001,004]
Command interpreter DCL
Login flags None
Priority Value of the system parameter DEFPRI
Resources Values of the PQL system parameters
