best commands to move data to new storage

[Ricky_4]

Hi All,

We are moving all data from SC10 to EVA3000. Data from sc10 are oracle and applications binaries and also oracle datafiles. We will do it while database is offline. Please assist us of what is the best command should we use to to successfully migrate those data. This comamand should preserve permission, symbolic links and date of the datafile.

Will highly appreciate your assistance.

Regards,

Adriatico

cpio will be the fastest. Use the puddle-mov e options:

cd /old_directory
find . | cpio -pudlmv /new_directory

find , assumes that there are no 'hidden' files, those that start with a period such as .profile and .exrc. If there are such files, use:

find . [.!]* | cpio -pudlmv /new_directory

The .[!.]* makes sure that .. is not matched and sent to the new location, yet finds all the 'dot-files'.

Actually, I have found vxdump/vxrestore to be fastest:

vxdump -0 -f - -s 1000000 -b 16 /zmnt/oracle | (cd /oracle; vxrestore rf -)

Where /zmnt is old filesystem and /oracle is new.

cpio would be the best.

Also, I believe cpio won't handle files bigger then 2GB.....

Hi All,

The oracle datafiles from SC10 are more than 2 Gb. Aside from that, Oracle and applications will also move to EVA3000. So if cpio could not handle this what should be the command are appropriate in our migration. Please also consider oracle and applications binaries in the command you will provide.

Thanks in advance.

Yes i forgot to mention that cpio will not handle files with bigger sized files.I would prefer u can use either IgniteUX or fbackup to backup and restore it into ur newstorage.The advantage is that u can have a back up too before the migration

Also you can try rdist using various options. This basically helps in maintaining copies of files to different hosts.
