Nice trick. I wonder whether you saw an Oracle-l posting

Unfortunately i do not have access to a linux server to try the method, but as the post suggest it could elminate the extra step of having to rman copy and then switch to the file

Slick trick! Others might have reported this before, but its the first time I’ve seen it.

It seems to be rather dependent on the implementation of /proc. I have seen lots of *nix variants with little or nothing implemented there, but this ought to work on a pretty wide variety of platforms. Not that I’m volunteering to try.

Frits,

Great article! I wish I had read it 4 months ago :)

The metalink note however I find disturbing. It think it will corrupt your database. I will check it out.

Mmh, I’ve covered this already: http://frits.homelinux.com/wordpress/?p=20

After that, oracle also made a metalink note about it (ML:444749.1). When asking them about a note with the same information as in my blogpost, they responded it came from an internal note which was around.

I’ve tested this with linux 32 & 64 bit and solaris.

Well done, Christo! I knew there was a way to do this, but haven’t tried to figure it out. Thanks for saving me a lot of work!
