z/VM: CP Commands and Utilities Reference - z/VM - IBM

ENTER key as input to the virtual machine at the initial VM READ. Your
PROFILE EXEC is automatically executed if it exists on your file mode A.
BATCH
indicates that the CMS IPL is being performed in a batch instead of an
interactive virtual machine.
Use of this parameter does not affect execution of the SYSPROF EXEC.
Execution of the SYSPROF EXEC is suppressed only if the NOSPROF
parameter was specified.
At the beginning of each job, the batch facility work disk is accessed and
immediately erased, preventing the current user job from accessing files that
might remain from the previous job. Because of this, execution of the PROFILE
EXEC is disabled for the CMS Batch Facility machine. However, if the
BATPROF EXEC exists on an accessed system disk, it is invoked instead of
the PROFILE EXEC.
FILEPOOL filepoolid
specifies the default file pool that is established as the user’s file mode A. If
FILEPOOL is not specified, 191 is established as the file mode A.
The following parameters are ignored by the SYSPROF EXEC, but processed by
CMS initialization.
NOSPROF
indicates that the SYSPROF EXEC is bypassed. You must specify NOSPROF if
you intend to enter the CMSBATCH command when the initial VM READ is
issued. When the SYSPROF EXEC does not exist, you do not have to specify
NOSPROF to enter the CMSBATCH command.
INSTSEG YES
links the default CMS installation saved segment for this CMS session. The
CMS installation saved segment is an optional shared segment that contains
EXECS and editor macros that your installation provides.
INSTSEG NO
indicates that you do not want to use the CMS installation saved segment
during this CMS session.
INSTSEG name
links the named CMS installation saved segment for this CMS session. The
segment may be a physical or a logical saved segment.
SAVESYS sysname
is used in the process of creating named systems. The SAVESYS parameter is
available only to Class E users. It saves a virtual machine storage space with
registers and PSW as they currently exist. The operand sysname must be a
predefined name representing a definition of installation requirements of the
named system. The definition indicates the number of pages to be saved, the
DASD volume on which the system is to be saved, and the shared segments, if
any.
After the system is saved, initialization continues, all CMS parameters entered
on the IPL command are ignored, and SYSPROF EXEC is processed. The
parameters entered on the original IPL command are not passed to SYSPROF
EXEC.
