LOGON Use the command to identify yourself to the system and to
access that system. The format of the LOGON command is:
r ,Loqon userid [ password
] [ Mask] [ Noip1] I Loqin
1 1

to "Note" under description of password operand.
___ 1 user id is the identifier assigned to you in the VM/370 system. is vour password. Specify this field if no protection (that
is, masking characters) is desired. MASK NOIPL NQig: If your installation is using the password suppression fa=i1ity, an INVALID FORMAT message is issued when a user
attempts to enter the system LOGON password on the command
line. The user must wait for the ENTER PASSWORD response
before typinq in the password. This facility improves system
security because the password is automatically masked.
types masking characters to cover your password on typewriter
terminals without the print inhibit feature. The mask types on
the line following a prompting message from VM/370 requesting
you to enter your password. Should you forget to ask for
masking when you type LOGON, you can press the carriage return after the prompt for the password types, and VM/370 then types
out the maskinq characters. that the IPL device or name in the VM/370 directory shou11 not be used for an automatic IPt. 1. Upon successful 10qon, VM/370 creates a virtual machine
configuration from information in the VM/370 directory. The LOGON command name may not be entered using any line-editing symbols, but
the may use these symbols. See the for a detailed description of 10qon procedures. 2. If YJU ase LOGON because a teleprocessing line or error you from your virtual machine, you have 15 minutes to loq on again. If you do not log on within 15 minutes, your virtual machine automatically logs off. In this case, you may have to reconstruct files and restart jobs interrupted by the
teleprocessing line or terminal error.
3. If vou previously issued the DISCONN command to run your virtual without a console and then issue the LOGON command to reconne=t your console, certain SET and TERMINAL command operands are forced off even if they were on prior to issuing the DISCONN Section 5. Format of CP Commands 99
LOGON a reconnect, CP resets the linedel character to the
one specified in the directory (the default value). Therefore, if
you issue the SET or TERMINAL command with more than one operand
and you specify an operand that is reset following a disconnect, re-issue the same SET or TEFMINAL command again after you are reconnectea. Issue the QUEFY SET and QUERY TERMINAL command lines check which functions are currently active.
4. During the virtual machine logon process on a VM/310 system
generated for attached processinq operation but operating in
uniprocessor mode, a message is sent to the user with attached AFFINITY set (via the user directory's OPTION statement) the AFFINITY setting of his virtual machine is nullified by
the system's uniprocessor mode of operation. 5. If the LOGON/AUTOLOG/LINK journaling facility is activated, accounting records are produced for unsuccessful logon attempts
with incorrect passwords. If system defined values are exceeded
attempting to logon with trial passwords, a message is issued to an userid and the LOGON command is disabled. The default
is four incorrect loqon passwords. ENTER PASSWORD: that the userid has been accepted. You should type in
the password, or signal a carriage return if a mask is desired for.
