AUTOLOG Use the AUTOLOG command to log on any virtual machine that is defined in
the Yft/370 directory.
The virtual machine logged on operates in disconnect mode. The
virtual machine being logged on with the AUTOLOG command must have an automatic IPL defined in its directory and is allowed to issue one read
to its virtual console. The same restraints that apply to any
disconnected machine also apply to virtual machines logged on with the AUTOLOG command. The for.at of the lUTOLOG command is: AUTOLOG userid
userid password [variable data]
is the user identification of the virtual machine to be logged
on.
password is the password for the virtual machine to be logged on.
variable data
is the information that is passed to the ¥irtual machine when a virtual SIO is issued to the virtual machine's console. Up to 108 bytes of data may be placed in this field. If no
variable data is entered, the field is padded with blanks.
Bote, embedded line-edit characters in this file are treated
as data.
1. AUTOLOG is automatically invoked after Y8/370 initialization if the Y8/370 directory contains a userid of lUTOLOG1. Then, with a
suitable PROFILE EIEC, other virtual machines can be logged on and
brought online (for example, the batch virtual machine). I 2. If LOGOB journaling is not being used, and an lUTOLOG co •• and that I includes a password is issued from a virtual machine, CP determines I if the password is correct. If the password is incorrect, a count I of such incorrect passwords is maintained by CP. When a total of I four incorrect passwords have been entered, an error message I issued and the AUTOLOG command from the virtual machine I disallowed. lUTOLOG can still be issued directly from the terminal t (that is, in CP console mode). 3. If LOGOB journaling is OB, the count of incorrect passwords is incremented without regard to the of the co.mand. When the
installation defined limit of invalid AUTOLOG passwords is reached,
(as specified in the SYSJRL macro of D6KSYS) AUTOLOG is disallowed
regardless of how it is entered. 4. If password suppression bas been generated, the password may be
included on the com.and line only if the AUTOLOG co.mand is in an EXEC or ftODULE running under CftS. Otherwise, all data following
userid is assumed to be variable data and the password is read fro.
the terminal.
