Hi Burhan,

The patch doesn't require a reboot, can you check the following:

# swlist -l fileset -a state -a patch_state PHCO_32438

Make sure above output you see the "state" is "configured". If "installed" stated, please "swconfig PHCO_32438 \*" to configure it.

Also, run cksum for the following files and make sure the value is the value as shown below:

225566991 389120 /sbin/pax
410241828 90112 /usr/bin/pax
4106078265 6380 /usr/lib/nls/msg/C/pax.cat

If there is discrepancies found, please consider to reinstall the patch.

Hope above help to resolve your issue.

Hi,

Did swlist give the configured state as result?
Does your Filesystem support largefiles:
fsadm /home/oracle

If not, do the following:
fsadm -F vxfs -o largefiles /home/oracle
for more info do a man fsadm_vxfs.

PHCO* patch most of the time don't need a reboot.

the file which is > 2GB is on /u03 volume and this volume accepts >2 GB files.
is it necessary to have /home volume to accept large files > 2GB??.
is it safe to change /home to accept >2GB files??
is it possible to change the home to a volume that accepts >2GB files??

best regards

Hi,

In fact you don't want users to put big files in there home-dir.
If you want files greater than 2 Gb in a directory make sure the large file option is set.

Goodluck

dear Darrel Louis
the source file system for (tar) accepts large files. but /home does not
is it necessary to change /home to accept large files.
note that I use a cron job to schedule the backup script, and the home directory for oracle user is /home/oracle
whats wronge .. why it still give the same problem.

Hi,

If you want to save a file in /home,
which is greater than 2Gb, /home should be mounted with the largefiles option.

Can't you create a folder called /backup, with it's own mountpoint, and backup the oracle DB in this directory.

If /home gets full it might be that users can't login.

Hi,

Is it working when you dump it to a directory?
If yes log a call with HP.
Do you have the latest tar patch?

How large is the file? The 2Gb limit is for industry standard, while the patch allows pax to handle up to 8Gb (similar to a tar patch). Files larger than 8Gb must use fbackup or a commercial backup program.

dear Bill
the file size is not greater than 8 GB.

Check to see where your tar command is found:

whence tar

Use the what command to see if the tar program has actually been patched:

what /usr/lib/tar

Now, are you using tar or pax? The patch you listed is for pax. What is the command you are using? There is a separate patch for tar to handle up to 8Gb files: PHCO_28992

You can change the filesystem to largefiles online if you have OnlineJFS installed (and licensed), and the filesystem is vxfs (JFS), then just run the following:

fsadm -F vxfs -o largefiles /mountpoint

If not, you have to create a new mount, when you newfs it, specify -o largefiles. Mount it somewhere and migrate home, if you want this to be a permanent option.

OnlineJFS is better, but it's a bit pricey.

Your problem appears to be more filesystem side, but you might want to consider GNU tar. It has a lot more options, handles absolute file paths better, and supports largefiles natively.

From the porting and archive centre:
