Morning Janine,
I'll let someone else do the RMAN stuff, I'm not on 11g yet.
However, I have spotted one of my (many) bug-bears in your code, hard
coding Oracle locations, paths etc. I've had to sort out quite a few
problems of systems not working properly caused by having more than one
version of Oracle binaries on PATH and/or LD_LIBRARY_PATH at the same
time!
If I may, respectfully, suggest that you replace this:
ORACLE_SID=afghan
ORACLE_HOME=/u01/app/oracle/product/11.2.0/dbhome_1
LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$ORACLE_HOME/lib
PATH=$PATH:$ORACLE_HOME/bin
With this:
ORACLE_SID=afghan
ORAENV_ASK=NO
. oraenv
ORAENV_ASK=YES
And now, regardless of how often you upgrade the database, change the
home etc, you always get the correct setting for ORACLE_HOME, PATH,
LD_LIBRARY_PATH etc. Have a look at the code in /usr/local/bin/oraenv to
see what it does. The good thing about doing it this way is that
previous values of PATH and LD_LIBRARY_PATH are edited to remove any
previous ORACLE_HOMEs from the setting before adding in the newly set
ORACLE_HOME. This prevents you having multiple versions of Oracle
software on PATH or LD_LIBRARY_PATH - which is a nightmare!
Granted, in your script it's not a great problem, however, when someone
copies this script to use for something else, it could cause problems!
(Ask me how I know!)
I notice that you are doing this:
RMAN=$ORACLE_HOME/bin/rman
Have you fallen foul of the problem where there is a file called 'rman'
under the X11 binaries then? I know I have, frequently! What I do to get
around this is the following, in my login .profile (or equivalent):
export RMAN='$ORACLE_HOME/bin/rman'
Using the single quotes means that regardless of the specific
ORACLE_HOME I am currently using, the version of rman I access via $RMAN
will always be the one from the current ORACLE_HOME.
Hopefully an rman 11g guru (hello Robert et al) will chime in and advise
on the rest of your script.
Good luck with rman.
Cheers,
Norman.
