Copying permissions

[Borozinetz Oleg]

I,m newbie in hpux administration. I'm trying to find a way to copy file and directory permissions between two identical directory trees. I need this because on one of my oracle installations permissions were corrupted by wrong chmod command and I want to restore default permissions. Thanks in advance.

Hello,

If the files are exactly identical, you can use cp -rp from the good dir to the bad dir.

Hope this helps

You can use -p option, man cp for more.

Warning! One of my DBAs tried to upgrade a system by doing a 'cp' and I kicked his *&^%$ for it!

If you absolutely, positively have to use 'cp', check that the files in $ORACLE_HOME/bin that need to have the Sticky Bit set.

Some of these files are,...
dbsnmp
oemevent
oracle
oracle0
oratclsh
tnslsnr
tnslsnr0

If you can, I would recommend either a recover from Backup, or a re-install.

Share and Enjoy! Ian

I totaly agree with Ian. Oracle copies never should be done with a cp nor cp -rp.

If a chmod was destructive, you should recovery a backup in a seperate tree. Do a 'ls -la tree1 > /tmp/out1' and a 'ls -la tree2 >/tmp/out2'.
Then a 'diff /tmp/out1 /tmp/out2'.
This will give you exact info about the changes.
And even then you should be very carefull. Oracle should be inactive while touching the files.

You could use cpio or tar

CPIO
# cd
# find . -depth -print | cpio -pmdvl

TAR
# cd
# tar cf - . | (cd ; tar xf -i )

Alternatively, if you want to copy whole Filesystems (i.e every thing in /dev/vg01/data which is mounted on /data say)

# umount /data
# dd if=/dev/vg01/rdata bs=64k of=/dev/vg??/rnewdata
# mount /dev/vg01/data /data
# mount /dev/vg??/newdata /newdata

Hi,

I would always prefer restoring from a backup rather then using cp for Oracle.

But you can give a try with the cpio command. I think that it works.

Be in the directory from where you want to copy the files.

#cd /oracle

# find . -depth -print | cpio -pdlmuv /destination_dir

This command will copy all the files from /oracle directory to the /destination_dir.
