Why execution status of stored procedure in shell script is returning same?

Question

Hi Friends,
My shell script has below code to execute Pl/Sql procedure.depending on pl/sql procedure status i need to execute the script further.
i am testing error condition.So i kept exe instead of exec for executing procedure.it suppose to return non zero.But iam not getting the correct status in shell script using $?.
even for error condition also status is returning zero(0).How to catch execution status of stored procedure in shell script?
can you please me suggest whats is wrong in below code?
echo "*************************************************************"
echo "             cleaning replica tables"
echo "*************************************************************"
sqlplus -s migrat/****@dotis01<<ENDOFSQL
WHENEVER SQLERROR EXIT 1;
exe PKG_OTU_HELPER.SP_CLEANUPREPLICA;
Commit;
exit;
ENDOFSQL
status=$?
echo $status // showing 0 always.
+if [ $status -ne 0 ]+
then
echo "issues in cleaning in replica tables"
exit;
fi
+#Loading of data from flat files to migration tables using sqlldr programs+
echo "*************************************************************"
echo "      Loading of data from flat files to migration tables"
echo "*************************************************************"
sh /opt/finaclesoftware/UBS_10.4.02_AIX/AIX/DB/CRM/Oracle/OTU/Retail/ControlFiles/LoadData1.com

The whenever sqlerror clause is a sqlplus command. When Oracle (that is, the sql engine of the pl/sql engine) raises and error in a sql statement, the whenever sqlerror command determines what happens.
Exec is also a sqlplus command, exec <procedure> is shorthand for begin <procedure> end;, that is, it creates an anonymous block.
Your misspelling of exec as exe is not an Oracle error, it is a sqlplus error. The command never actually gets to Oracle, so there has not been a sqlerror for whenever sqlerror to respons to.
Consider, I do not have a procedure called p
SQL> desc p
ERROR:
ORA-04043: object p does not existI try to call it with exe as in your code:
SQL> exe p;
SP2-0042: unknown command "exe p" - rest of line ignored.Note the error message is form sqlplus (SP2).
But, if I call it correctly usinf exec:
SQL> exec p;
BEGIN p; END;
ERROR at line 1:
ORA-06550: line 1, column 7:
PLS-00201: identifier 'P' must be declared
ORA-06550: line 1, column 7:
PL/SQL: Statement ignorednow I have a sql error, and whenever sqlerror exit 1 would quit sqlplus with a return value of 1.
