Using the System Generator (SYSGEN)
Entering the SYSGEN Global Module
Entering the SYSGEN Global Module
The command for the SYSGEN utility is SYSGEN. SYSGEN has four positional parameters:
SYSGEN [
basegroup
]
[
,newgroup
]
[
,inputfile
]
[
,outputfile
]
The
basegroup
parameter specifies the group in the SYS account that contains the
configuration data file set to be used or changed. The default base group is the group used
to boot the system (usually CONFIG). The default base group is the group specified in the
initial system load (ISL) START command line. (For information on specifying configuration
groups during START, refer to Chapter 3 , “System Startup Functions.”)
If you attempt to specify a nonexistent group using the BASEGROUP command, SYSGEN
issues the following message:
**error** group
groupname
does not exist
The
newgroup
parameter specifies the group used to store data. If you do not specify
newgroup
, SYSGEN stores any configuration changes in the base group by default.
If the group specified by
newgroup
already exists, SYSGEN asks, at keep time, whether or
not it should overwrite that group with new information. At keep time, if the user does a
KEEP with no parameters, SYSGEN keeps the current base group unless
newgroup
was
specified, in which case the group given is used. More information on using the KEEP
command is provided later in this chapter.
The
inputfile
parameter specifies the file designator of the file for command input. The
formal file designator is SYSGIN. The default is $STDINX.
The
outputfile
parameter specifies the file designator of the file for SYSGEN output. The
formal file designator is SYSGOUT. The default is $STDLIST.
When using parameters with the SYSGEN command, place them immediately following the
command:
:SYSGEN[
basegroup
][,
newgroup
][,
inputfile
]
[,
outputfile
]
When using parameters with RUN SYSGEN.PUB.SYS, you must specify them in the phrase
INFO=" ":
RUN SYSGEN.PUB.SYS;INFO=
"[
basegroup
][,
newgroup
]&
[,
inputfile
][,
outputfile
]"
Example 4-1 illustrates activating SYSGEN’s global module. Activate the SYSGEN global
module by entering the command SYSGEN or by entering RUN SYSGEN.PUB.SYS.
