I am new to UNIX shell script programming. I have coded one korn shell script used on solaris 10 for Oracle database rman cold backup. The first part of script is working. But only following part is not working. Please help me to point out the problem and errors in my code. Thanks a lot.

# the first part has been omitted.

# Started to shutdown database and startup database mount for cold backup .

${ORACLE_HOME}/bin/sqlplus -s << EOF
conn / as sysdba
shutdown immediate;

${ORACLE_HOME}/bin/sqlplus -s << EOF
conn / as sysdba
startup mount;

# The above part works, then script stop here.


exit

rman NOCATALOG <<EOF
CONNECT TARGET SYS/$SYS_PASSWORD@$ORACLE_SID
if [ $? = 0 -o $? = 2 ]
then date +"%D %T: backup process started." >> pdedev$BACKUP_DAY.LOG
else date +"%D %T: Error start rman to do backup." >> pdedev$BACKUP_DAY.LOG
exit 1
fi

FORMAT = '$BACKUP_FOLDER/%d_DB_%u_%s_%p' MAXPIECESIZE 5G;

}
if [$? = 0]

echo " database $ORACLE_SID is up running." >> $BACKUP_DAY.LOG
