Hello everyone, 

I'm digging through rman again.  Wish I had more time to do this ongoing.
I've looked at the v$views in the past, but didn't dig into them too deeply.


Now that my backup strategy is backup to disk -> wait for media manager to
take files to tape, I'll need to be able to intelligently tell my SA what
files I need should a restore become necessary.  I don't have the luxury of
a recovery catalog. However, it looks as if the v$ views in the target
database will tell me what I need to know. 

Has anyone ever seen an erd or some documentation stating the relationship
between these views?  I know that the important ones (so far - v$backup_set,
v$backup_datafile, v$backup_redolog, v$backup_piece) are related by
set_stamp and set_count.  I'd like to be able to create an erd for the dba
that will be covering when I'm out on leave. 

Does v$log_history relate back in somehow? 

Another thing I'm looking at is deleting old backups.  I've been messing
with the CHANGE command but it only references backupset and backuppiece.
Would I have to give this command for every archive log that I am ready to
get rid of?  Or is there a twist to this command that will get rid of the
backup piece that contains the archive logs?  

Thanks in advance for any pointers, websites, etc.
