RE: Tuning RMAN backup and recovery

If you're talking about blksize, it has been deprecated in 10.1+ :

http://download.oracle.com/docs/cd/B19306_01/backup.102/b14194/obs_comm.
htm#RCMRF910

But it is still recommended in this best practices guide (p.10):

http://www.oracle.com/technology/deploy/availability/pdf/S942_Chien.doc.
pdf

So, I'm not sure if it's still a good idea or not.  Have you actually
tested with it in 10g to see if it works?

Here's another white paper on best practices for 10g specifically with
Netbackup, from HP, that also suggests using BLKSIZE.  I haven't read it
yet, but looks interesting:

Blocksize - this is used to set the buffer size in allocate channel
maxfilesopen - going to disk the default (16 IIRC) is too high. Scale it
down and test.
