Question

I want to run the hot bkup from a current Unix script but not sure what i to be changed because i'm very new to Unix scripting.
Please help.
## script -s <sid> -b <hot/cold> -d </backup/destination directory>
## Critical Env. Variables Verify CNTLFILE Directory File !!!
Setup()
export CNTLFILE=/opt/app/oracle/dba/cntl/backupcntl.sh
if [ ! -f $CNTLFILE ]
then
echo "-- ERROR: CNTL FILE $CNTLFILE does not Exist !!!"
echo "-- ERROR: CNTL FILE $CNTLFILE does not Exist !!!" > /tmp/backuperror
echo "-- Backup Aborted !!" >> /tmp/backuperror
mailx -s "Backup Fail for $ORACLE_SID" $DBA_MAIL $DBA_PAGE < /tmp/backuperror
exit 1
else
if [  -f $CNTLFILE ]
then
. $CNTLFILE

Answer 1

Your script defines functions which will enable you to invoke the backup. But this script only defines functions. You need to invoke them for your backup to work. The sample invocation can look like this (CODE NOT TESTED!!!):
Setup
Initialize
Gethottblspace
BeginHotbackup
