SYSGEN Changes
by Doug Claar--Commercial Systems Division
Beginning with MPE XL Release 2.1, several changes were made both to
support changes in the Operating System, as well as to improve several
aspects of SYSGEN.
THE IO CONFIGURATOR
There are several changes in the IO configurator. Of these, the most
visible is the change in the LDEV command's output format. Also, a new
device mode was added for configuring Native Language peripherals.
A New Ldev Listing Format
The new Native Mode Spooler affected SYSGEN in a couple of areas, but the
most visible was the LDEV command. Where before, the logical device
listing fit in 2-3 lines on the screen or 1-4 lines offline (depending on
how many classes were used), it now takes 4 lines on the screen and 3
lines offline, no matter how many classes are used. In the process, the
output format has changed from a SYSDUMP-like appearance to a format
resembling SYSGEN's LPATH command.
The change in SYSGEN format was necessary because of the addition of the
device name field to the list of things that SYSGEN had to display, as
well as the decision to begin displaying CM type and subtype.
One side benefit of the new LDEV display is that NMMGR devices are
grouped together where possible to minimize the amount of space they take
in the display.
Supporting Native Language Peripherals
The new device mode, NLIO, to supports the configuration of Native
Language capable devices. SYSGEN now knows which products can be
configured for Native Language use, and if a specific product should
default to enabling Native Language or not.
For a device that can not be configured for Native Language use,
specifying ADEV...MODE=NLIO will generate an error. If the device can
be configured for Native Language use, then it will default to
MODE=(NLIO,OUTPUT) if the only or primary use of the device is as a
Native Language device; otherwise, it will default to MODE=OUTPUT. Either
default can be overridden by explicit use of the MODE parameter in the
ADEV and MDEV commands.
For example, the HP256x family of printers can be used as Native Language
printers, yet that is not their only use. To enable their Native
Language capability, the MODE=NLIO parameter must be specified. For
example, to add a HP2567C printer at path 2/4.2.6 with a ldev of 19 and
native language capability, you could issue the command:
ADEV 19 2/4.2.6 HP2567C MODE=NLIO
MISC CONFIGURATOR CHANGES
In the MISC configurator, the SPOOL command and the SPOOL option of the
SHOW command are no longer available. With the Native Mode Spooler, the
functionality that this command provided is not needed anymore. Scripts
that contain these parameters will continue to work for a while, but will
stop working sometime in the future. So it is a good idea to change all
of your SYSGEN scripts at this time.
There is also a new command visible: The IO command. The IO command
defines to the system the number of "slots" to save in certain
Compatibility Mode tables (the IDD, ODD, and XDD) for devices that are
configured later in the system startup process. These values should only
be changed at the direction of HP personnel. The SHOW command has been
enhanced with an IO parameter to show the IO values.
The STACK command's non-CM parameters (NM, MAXNM, HEAP, MAXHEAP) are now
functional, and are specified in bytes. You'll notice that the numbers
reach almost up to 1 GB. When you update to MPE XL Release 2.1, the old
values are automatically adjusted for you, but any SYSGEN scripts
containing these parameters will have to be manually changed.
TAPE COMMAND CHANGES
Beginning with MPE XL Release 2.1, a user with OP capability can cut a
SYSGEN tape unless configuration changes have been made. Under certain
rare circumstances, SYSGEN itself can make configuration changes to bring
parameters into the appropriate range. Should this happen, a user with
SM capability must run SYSGEN and do a KEEP to save SYSGEN's changes.
