question about Time finder Mirror options

have you looked in Timefinder documentation ? How about "man symmir" or "symmir -h"

more or less ...you have to put forth some kind of effort right ?

Is it a polite way to say "RTFM" ??

Just to explain that F stands for Fantastic!

I understand pretty well ..
Your answer is almost the same we use in our internal mailing lists when we catch similar questions

From a storage point of view, option 2 is really good since you can leave the DB running and you don't need knowledge of either the host or the database. You simply ask the storage to freeze the ios and obtain a copy that looks like the image you have on your disks when a cluster switches node due to a node failure.
It's consistent even if you need a little FSCK and DB recovery.

i think option 4 is the best solution. Take a look at this white paper:

That's how we roll.

Hi

I did not explain my issue sorry about that,

I have a server running AIX OS and Oracle Database 10G, I'm Associating a BCV Mirror Device to its standard devices, I split the paired devices by using -instant option, due to I have power path to get a consistent copy.

/usr/symcli/bin/symmir -g isis_bcvkio -instant split -noprompt -i 30

There are many ways to split the devices to get consistent copy

1. -instant option(for power path)
2. -consistent (without the use of PowerPath support)
3. symioctl command
4. Freeze database by using database scripts( Database administrators)

I don't know what is the best way to do that, I think the option 4 is the best way to do a consistent copy.

Sorry about that, could you help me please?

Regards
