SET PAGEX command with the ON operand. For more information, see Usage
Note 2 on page 1310 in the description of the SET PAGEX command.
9. Care must be used when passing parameters to a named saved system
(system_name). Named saved systems may expect certain registers to be
initialized when they are given control. Indiscriminate use of the PARM
operand could overlay a previously initialized register, causing unpredictable
results.
10. When system_name is equal to a hexadecimal device number, the device is
IPLed if it exists; otherwise, the named saved segment is IPLed.
11. If you do not want leading blanks or embedded blanks in the load parameter,
you may specify the load parameter as a single blank-delimited token.
Specifying the load parameter within single quotation marks enables you to
specify leading blanks or embedded blanks.
12. The load parameter may not contain a X'15' character.
13. You may specify both the LOADPARM and PARM options when IPLing by
either vdev or system_name. Both options may be specified on the same
command line. However, if you specify the PARM option, it must be the last
option on the command.
14. If you IPL an NSS that was created with the VMGROUP option on the
DEFSYS command, your virtual machine becomes a member of the virtual
machine group that is known by the NSS name. Members of a virtual machine
group are permitted to connect to the signal system service and to provide
intragroup signaling, including awareness messages (signal-in and signal-out)
about members joining the group or leaving it.
If your machine is a member of a virtual machine group, a user with an
appropriate privilege class may authorize trace data recording into a system
data file for the group by issuing a TRSAVE command and specifying FOR
sysname.
15. If the tape drive specified is in a Given State, the issuer must be the user ID to
whom the tape drive was given, or the command will not be performed.
16. This command terminates all Concurrent Copy (CONCOPY) sessions for your
virtual machine.
17. If the IPL command is entered without abbreviation, (that is, is entered as IPL
rather than I or IP), the command is accepted without parameters. When IPL is
entered without parameters, the system repeats the operation of the last
successful IPL command entered, or responds with an error message if there
was no previously successful IPL.
18. If an external security manager is installed on your system, you may not be
authorized to enter this command. For additional information, contact your
security administrator.
Optional CMS Initialization Parameters: The following CMS parameters are
passed to the system profile EXEC (SYSPROF EXEC). Any unrecognized
parameters are ignored by CMS initialization, but are still passed to the SYSPROF
EXEC. For more information about the SYSPROF EXEC, see the z/VM: CP
Planning and Administration book.
CMS users can use the PARM operand to specify any of the following CMS
parameters:
AUTOCR
is the automatic carriage return parameter that simulates the pressing of the
