Kernel/Itanium

[Nobody's Hero]

I have a new Rx running 11.23, trying to load up oracle. The box is Hpar x 2. Partition 1 is for the oracle instance.

I am trying to import oracle using a pipe,
and I get an error about "unable to read a file larger that 2 Gbytes. I've had this before but can't remember what to do.

In the kernel I changed all th *max* parms up as high as possible. Anyone ever had this problem.

ulimit shows 'unlimited'

Problem reading a file over 2 gbytes.

Hi Robert:

There is no kernel parameter to control largefiles. Rather, you need to enable 'largefiles' for the filesystem in which you wish to store files larger than 2GB.

# /usr/sbin/fsadm -F vxfs -o largefiles /dev/vgNN/rlvolX

Note the use of the raw device. You do not need to unmount the filesystem if you have OnlineJFS.

Regards!

and you've checked that the filesystems support large files?

fsadm -F vxfs /dev/vgname/rlvol

hope this helps,

Thanks, but I am aware of this.

All filesystems have enabled "creation of large files"

This has to do with the ability to read limit on a file per process, or something like that.

Here is the limit for oracle:
ltcps1:oracle> csh
ltcps1 1: limit
cputime unlimited
filesize unlimited
datasize 4194300 kbytes
stacksize 392192 kbytes
coredumpsize 2097151 kbytes
descriptors 2048 files
memoryuse unlimited
ltcps1 2: limit -h
cputime unlimited
filesize unlimited
datasize 4194300 kbytes
stacksize 392192 kbytes
coredumpsize unlimited
descriptors 4096 files
memoryuse unlimited

hmm.. I can't think of any related kernel parms.

Would you mind posting details on the process/steps involved w/ the import and pipe. Is ssh/rsh being used anywhere? How is it kicked off.. etc.

Hi (again) Robert:

Ah, Oracle imports and exports. If I recall correctly, you will need to 'split' your export and import the split files. This might help:
