[Rajesh Karelia]

Hi All,
this is my first question on the forum. I would like to know what the maximum file size ossible on HP-UX.
We have Oracle server running on HP-UX and the size of datafile can reach upto 15MB to 18MB.
Is this possible on HP-UX?
Thanks,
Rajesh

Rajesh,

In hpux you are allowed large files, up to 2gb, without specifying that largefiles are allowed when creating a filesystem. If allowed largefiles on creation, or changed to allow largefiles then no filesize limit.

"15MB to 18MB" is considered "tiny" file sizes these days. Did you mean 15 to 18 Gigabytes?

With VxFS/JFS 3.3 and above AND fileystem version 3 and above, your biggest file size is only limited by the biggest size of the filesystem which is 2TB.

With the later version of HP-UX11i and VxFS/JFS 3.5 and filesystem version/layout 5+ AND using VxVM, your maximum filesystem size goes up to 32TB. But Still, your maximum filesize remains at 2TB.

Hi

The above replies answers your question. If you want to have file size more than 2 GB , when u create the File system for Oracle , create them with the following option. and also remember to update the /etc/fstab with the largefile option. Otherwise , when the system is rebooted, these File systems will not mount ..

/usr/sbin/newfs -F vxfs -o largefiles /dev/vgXX/rlvolX

and in the fstab , add an entry ..

/dev/vgXX/lvolX /mountpint vxfs delaylog,nodatainlog,largefiles,rw,suid 0 2
