Hi guys,

thank you everyone.

Nothing is wrong with RMAN. The only issue is that I have never used it. I have stopped work with the Oracle on version 7 when RMAN did not exist. At the moment we are installing some hardware equipment at the customer site (storage) and I have discovered that customer do a backup only through the export. I have suggested that they should reconsider their backup strategy. Obviously, they have not been in position to do a recovery :o).

They have a SAN environment. Backup device is a MSL library with two Ultrium2 drives. Everything works over 2Gb Fibre channel.

Our suggestion is that they should use some standard backup software e.g. HP Data Protector, CA or something similar. Also, they would like to test online backup before they buy anything. So, my plan is to use as a first thing RMAN without catalog just to show them how it works. But, as far as I know Data Protecor use RMAN with the catalog. Correct me if I am wrong.

 So, right now I am testing and learning RMAN features :o).

After that, the will decide what to do next.

Of course, my first suggestion was that they should find someone who is experienced Oracle DBA :). At the moment, guy who works as an administrator on OpenVMS is also an Oracle administrator.

Perhaps, my plan is not so good, but at the moment I can not find anything better :o(.

If you have suggestions or you have some scripts that can be adopted with your permission, they are welcome. You will save my time :o).

Anyway, thank you once again for your time.
