kernel limitations

Post by Joao » Fri, 17 Oct 1997 04:00:00



hello!

I am using RedHat 4.1, kernel version 2.0.27.
Reg. Number 645677 support ID 7530fc

I am worried with the limit of file opens and record locks
I can get for each user session. I explain:

I've worked with a Dynix (Symmetry) Unix on which you
could  configure the kernel with such a parameter as
commercial/parallel/timeshare environment which was
used by the kernel to tune buffer cache and the number of open files
for any given user process. This setup has inpact in filename cache sizing,
buffer cache sizing and file and record-locking parameters for example.

In Linux kernel setup, I don't find any of these parameters, nor any
that could state anything about record locks available or limit number
of the open files.

Should I be worried or am I missing something?

Thank you.

Joao B.

I know there's the "ulimit" command that can be used to set various
limits, however I seem to remember that some limits are not
supported. Go to DejaNews, select the powersearch and search for the
keywords "linux" and "ulimit", on both the current database and the
old database. This should give you more info.

And for those who are wondering, no I don't have any relationship to
DejaNews, apart from finding it frequently more useful than the man
pages.
