sysconfig
This state applies only to static subsystems, which can be unconfigured but
cannot be unloaded.
• Unloaded (not available for use)
This state applies only to loadable subsystems, which are automatically
unloaded when you unconfigure them with the
sysconfig -u command.
Subsystems that are not being used can be unconfigured using the -u flag.
Unconfiguring subsystems can free up kernel memory, making it available
for other uses. You can unconfigure any static or loadable subsystem that
supports run-time unconfiguration. If you unconfigure a loadable subsystem, that
subsystem is also unloaded from the kernel.
You can use the sysconfig command to display the value of attributes on the
local system. If you want to configure, reconfigure, or unconfigure a subsystem,
you must be authorized to modify the kernel configuration. Only users who have
a system group UIC or who have an account with SYSPRV, BYPASS, or OPER
privilege can configure, reconfigure, or unconfigure the subsystems.
Parameters
subsystem-name
Specifies the subsystem on which you want to perform the operation. The
subsystem-name argument is required for all flags except -s and -m . If you omit
subsystem-name when you use the -s or -m flag, the sysconfig utility displays
information about all loaded subsystems.
attribute-list
Specifies attribute names and, depending on the operation, attribute values.
• For reconfigure ( -r ) operations, the attribute-list argument has the following
format:
attribute1=value1 attribute2=value2...
Do not include spaces between the attribute name, the equals sign (=), and
the value.
• For query attribute (
-q ) operations, the attribute-list argument has the
following format:
attribute1 attribute2...
The attribute-list argument is required when you use the -r flag and is optional
with the -q flag. Any attribute list specified with other flags is ignored by the
sysconfig utility.
Flags
-c
Configures the specified subsystem by initializing its attribute values and,
possibly, loading it into memory. Use this command whether you are configuring
a newly installed subsystem or one that was removed using the
sysconfig -u
command option.
-d
Displays the attribute settings in the SYSCONFIGTAB.DAT file for the specified
subsystem.
