Using idtune to reallocate kernel resources

You cannot use configure to change some kernel parameters because they are not generally considered to need adjusting.
If you do need to alter such a parameter, log in as root and use the idtune(ADM) command:

cd /etc/conf/cf.d
/etc/conf/bin/idtune resource value

resource is the name of the tunable parameter in uppercase as it appears in /etc/conf/cf.d/mtune (see mtune(F)).

value is the parameter's new value. After changing the parameter values, relink the kernel, shut down and reboot the system as described in ``Relinking the kernel'' in the SCO OpenServer Handbook.

You can use the -f option to idtune to force it to accept a value outside the range specified by the minimum and maximum values defined in mtune. If necessary, you can also use the -min and -max options to write new minimum and maximum values to the mtune file.

The following sections describe the parameters that can only be tuned using idtune:

• ``Boot load extension parameters''

• ``Buffer cache free list''

• ``Hardware and device driver parameters''

• ``Memory management parameters''

• ``Name cache parameters''

• ``Message queue parameters''

• ``Semaphore parameters''

• ``Shared memory parameters''

• ``STREAMS parameters''

• ``System parameters''

• ``LAN Manager Client Filesystem parameters''
