/opt/dcs ===> /temp/opt/dcs

Hi,
depending on why you are doing this,you could try and work with links.
See "man ln"

Hi,

the idea about a "prefix" is bad, because this will move all of /var or /opt to /tmp/var etc.
What do you want to do?
Just try to backup the directory like
/var/dcs using "tar".

HI

I need to migrate some application with oracle data base from server to another

and its recommanded to me from the personne ho devellop this application to have a prefix in all file system in the second server

If i use a link like for exemple :

ls -s /var/dcs /temp/var/dcs

we must have a new file system /temp with new disk or not ?
thank you in advanced

Assuming /var/dcs and /opt/dcs are filesystems in their own right and /temp exists, the easiest way is to edit /etc/fstab. Add /temp in front of these filesystems then reboot the system.

Before you do this I would ask if it is either necessary or desirable: maybe there is a reason for dcs being under /var and /opt. It could well be that links, as suggested earlier, are indeed your best solution.

Yes for /var/dcs and /opt/dcs its the result to the installation for the application

I have add this ligne in /etc/fstab ,but I can't see the difference when i use bdf

etc/fstab

/dev/vg00/lvol8 /temp/var/dcs vxfs delaylog 0 2

I think that i need to make a copie to /var/dcs in /temp/var/dcs
that's right ?

[Torsten.]

If you really do this:

etc/fstab

/dev/vg00/lvol8 /temp/var/dcs vxfs delaylog 0 2

prepare to say good bye to your OS ;-)

Once rebooted, the system will never find
/var or /opt.

If you want to store data in

/temp/var/dcs

consider to create a new LVOL and mount it there.

HI

NO I think taht i have a solution

I can create new file system with name /temp/var/dcs ,and If I mount this file with the same Lvol to /ver/dcs ,it will be the same lvol but in another diractory ,because the files is in the a lvol not in a diractory

i hve make a teste with /tmp and its work

Thank you very much and have a nice day

[MarkSyder]

Torsten is right - I did say you should do this only if /var/dcs and /opt/dcs were filesystems in their own right. Your reference to adding lines in /etc/fstab rather than amending lines suggests they aren't.
