916 z/VM: CP Commands and Utilities Reference
Use QUERY PASSWORD to determine whether you can include a password on the
command line for the AUTOLOG, LINK, LOGON, or XAUTOLOG command.
AUTOLOG
displays whether you must include a password on the AUTOLOG command
line.
LINK
displays whether you can include a password on the LINK command line.
LOGON
displays whether you can include a password on the LOGON command line.
XAUTOLOG
displays whether you can include a password on the XAUTOLOG command
line.
1. For security reasons, the password suppression facility permits your installation
to require that issuers of commands that require passwords do not include the
password in the command line. Instead, after the user enters the command
without the password, the system prompts the user to enter the password, and
the input field is masked.
2. See “SET PASSWORD” on page 1312 for an explanation of how to set
password suppression for the AUTOLOG, LINK, LOGON, and XAUTOLOG
commands.
3. If you enter QUERY PASSWORD using DIAGNOSE code X'08', you receive
one of the following return codes in your Ry register:
RC Meaning
0 Indicates that you may (must, for AUTOLOG) enter a password on the
command line.
4 Indicates that you cannot enter a password on the command line.
8 Error–the operands following on the command line are not valid.
4. System programmers responsible for z/VM security should examine the usage
notes for the PASSWORDS_ON_CMDs operand of the FEATURES system
configuration statement in z/VM: CP Planning and Administration.
