script error

[230173]

hi,

I'm trying to implement a backup script from a book called "oracle 8i backup and recovery by Rama velpuri"
On AIX 4.3.3
But i get the following error:

$ dbbackup spcbase
/opt/app/oracle/admin/backup/backup/dbbackup_begin spcbase hot >> /opt/app/oracle/admin/backup/db_admin/spcbase/log/backup_020409.log 2>>
/opt/app/oracle/admin/backup/db_admin/spcbase/log/backup_020409.err

I've looked in the script and i see nothing wrong.
He complaints on a grep statement.
This is the first statement with grep:

STATUS=`ps -fu oracle | grep "ora_[a-z]*_${DBNAME}" `

But if i do this on an prompt mline this works fine.

Help!!!

PS: what's "$?" ?
Does this mean any variable?

If you don't have enough info let me know and i'll send the whole script.


thnx

Please see my response in the AIX forum. Cheers.

$? is the return code from the last process run.

Are there any other grep lines? Mike
"Experience is the comb that Nature gives us after we are bald."

Is that a haiku?
I never could get the hang
of writing those things.

There are no grep lines beore this one.
The other grep lines are:

PROCS=`ps -ef |grep oracle${DBNAME} |grep -v grep |awk '{print $2}'`

try using debugging with: set -vx

put this a few lines into your script and you should be able to see exactly what your grepping for when it hits the grep statement or alternatively execute your script with: ksh -vx scriptname (replace ksh with sh/csh/bash.....etc).

I tend to find that a variable is NULL/EMPTY when this usually occurrs!
