The UnixWare 7 file size limit is 1 TB with VXFS. Some OS utilities have a limitation of 2GB.
On UnixWare 7.1.4 you do not need to do anything to get large file support, but to enable large file
support on prior versions of UnixWare 7.1.x, run fsadm.
# fsadm -Fvxfs -o largefiles /
# fsadm / * Note
# ulimit unlimited
# /etc/conf/bin/idtune SFSZLIM 0x7FFFFFFF
# /etc/conf/bin/idtune HFSZLIM 0x7FFFFFFF
# /etc/conf/bin/idbuild -B
* This should report "largefiles".
** 0x7FFFFFFF represents infinity for these values.
Reboot the system using shutdown.
By default, the entries in

HVMMLIM 0x9000000
To make changes to the kernel, use the
/etc/conf/cf.d/stune
root:
# /etc/conf/bin/idtune SDATLIM 0x7FFFFFFF
# /etc/conf/bin/idtune HDATLIM 0x7FFFFFFF
# /etc/conf/bin/idtune SVMMLIM 0x7FFFFFFF
# /etc/conf/bin/idtune HVMMLIM 0x7FFFFFFF
# /etc/conf/bin/idtune SFNOLIM 2048
# /etc/conf/bin/idtune HFNOLIM 2048
Then rebuild and reboot the kernel by issuing this command:
# /etc/conf/bin/idbuild -B && init 6
To tune the system, the proper parameter values to use depend on the number of users accessing the
application or database and size the of the database (that is, the used buffer pool). The following kernel
parameters can be set with idtune:
• (recommended setting: 128MB) and
SHMMAX
have an influence on the MySQL database engine to create user buffer pools.
• and
SFNOLIM HFNOLIM
• should be set to at least 3000/4000 (depends on number of users).
NPROC
• The following formulas are recommended to calculate values for SEMMSL, SEMMNS, and SEMMNU:
SEMMSL = 13
13 is what has been found to be the best for both Progress and MySQL.
SEMMNS = SEMMSL * number of db servers to be run on the system
Set to the value of
SEMMNS
you are running on the system at one time.
