I need to enlist the help of anyone who might be able to assist
me in a problem I'm having with the UNIX limit on the number of
sub-directories that may be contained in any one directory.
The application I'm working on creates a sub directory and a
couple of sub directories under that for each new "case". The
case number is a seven byte numberic field. As an example the
new case that is created has a case number of 23702. The
directory structure would be something like:
/usr
. /htc
. . /23702
. . . /primary
. . . /document
The problem I'm experiencing is that UNIX imposes a limit of 998
sub-directories ( plus . and .. which makes total of 1000) in any
one directory.
I'm running SCO XENIX 2.3.1 (soon to upgrade to either 2.3.2 or
SCO UNIX) and I'm wondering if there's any way of increasing this
limit, and if not I'm open to suggestions as to how a workaround
might be accomplished.
Thanks in advance
Keith...

If you can change the application, make it put stuff in: /usr /htc /23 /23702 /primary /document /23703 /primary /document /24 /24001 /primary /document In other words, use the first two digits as an index into a superior directory. Then you'll have 1000 max entries in each level. (1000 entries is still wayyy too much to search through, though. Why are you making the unix filesystem do the job of a database?) If you can't change the application, throw it away. That's a silly mechanism (half :-). Just another UNIX hacker, -- /=Randal L.
