I want to control the execution of a PL/SQL procedure from a UNIX shell script.
Below, I include the script.
The control variable which should recive the return of the procedure, dosen't work well.
I want to control the return, because I wanr to make a UNIX script to control the execution of
a load data process with some Oracle procedures.


---

#!/bin/ksh

echo "Executing procedure pl/sql"
SQLPLUS="sqlplus -s /"
ESQUEMA="esquema1"
echo "\
call ${ESQUEMA}.Z_PROC_PRUEBA();" | $SQLPLUS
echo "Controlling pl/sql execution"
var_err=$?
if [ $var_err -gt 0 ]
then
echo "Error executing pl/sql"
else
echo "pl/sql finished sucessfully"
fi

This is neither an Oracle nor an Unix error message.

sqlplus will ALWAYS return 0.
You need a different mechanism to indicate an error; such as the existence of a file or not; or the contents of a file.

Thanks,
I have found one possible solution. I have included in the code executed by sqlplus the next sentence:

whenever SQLERROR exit 1

It works!!

---
#!/bin/ksh
echo "Executing procedure pl/sql"
SQLPLUS="sqlplus -s /"
ESQUEMA="esquema1"
echo "
whenever SQLERROR exit 1
call ${ESQUEMA}.Z_PROC_PRUEBA();" | $SQLPLUS
echo "Controlling pl/sql execution"
var_err=$?
if [ $var_err -gt 0 ]
then
echo "Error executing pl/sql"
else
echo "pl/sql finished sucessfully"
fi

I want to redirect the output of a PL/SQL procedure to a log file. In this file I want to have all the output of the execution, the results of every step, errors, etc..

I have tried with a UNIX pipe ( >> sql_log.txt) and with spool sentences, but it dosen’t work.

Can anybody help me??

Attached the UNIX script which call the procedure.

Any advice will be greatly appreciated.

echo "Controlling pl/sql execution"
var_err=$?

Of course var_err contains the return code from echo.

Otherwise, what does "it dosen’t work" mean?

And please read OraFAQ Forum Guide, especially "How to format your post?" section.
Make sure that lines of code do not exceed 80 characters when you format. Indent the code.
Use the "Preview Message" button to verify.

I’m using the attached script to control the result of the execution of a PL/SQL procedure from a UNIX script. It works well, but I have a little problem. If I include and ‘exception’ clause in the procedure to control errors, in this case the UNIX variable dosen’t recibe the error result, it recibes a 0. I include the exception in the PL/SQL in order to close cursors after an sqlerror. Is there anyway to return a 1 in the PL/SQL in the exception handler??. I want to control errors in the PL/SQL procedure and in the UNIX script, is tha possible??

Any advice will be greatly appreciated.


echo "Se ejecuta el procedimiento pl/sql"
#- El usuario de AIX debe tener permisos de ejec sobre el PL/SQL SQLPLUS="sqlplus -s /"
ESQUEMA="esquema1"
echo "
set serveroutput on
whenever SQLERROR exit 1
call ${ESQUEMA}.Z_PROC_PRUEB() ; " | $SQLPLUS > sqlout.txt
var_err=$?
echo "Resultado" $var_err
if [ $var_err -gt 0 ]
then
echo "Error al ejecutar el pl/sql"
else
echo "pl/sql ejecutado correctamente"
fi

yes, make sure your exception section contains a RAISE; in it.
