Maximum filesize limit

Erwin Vodegel_2 — Mon, 26 Sep 2005 08:40:49 GMT

Hello,

We are installing Oracle 9.2.06 and we have very large files (table files). We want to extend the maximum filesize limit to 500Gb.

Which kernel parameter do I have to modify? Which actions do I have to take?

Thanks in advance,
Erwin

What version of the OS are you running? What version of the VxFS filesystem?

If you are running appropriate versions of both, you just need to make sure that you have the largefiles option turned on for your filesystems.

Hi Erwin:

Whether or not this is posssible will depend upon your release and your JFS (VxFS) versions. For details, see the white paper, here:

http://docs.hp.com/en/5971-2383/5971-2383.pdf

You will need to enable 'largefiles' for the filesystem in question. See the manpages for 'fsadm_vxfs' for more details, too.

Regards!

Hi Erwin,

You should take a look at the memory advice given in this doc.
