SQL*Plus Overwrites Unix Command Signal Int ( KiLl -2 ) Trap in Calling Script (Doc ID 341412.1)

Last updated on AUGUST 14, 2017

Applies to:

SQL*Plus - Version: 9.2.0.5
This problem can occur on any platform.

Symptoms

Sqlplus is ignoring the trap to stop CTRL-C from ending sqlplus.

There are 2 scripts:
One that starts sqlplus:
myPlusTest:
-----------
sqlplus -s  user/password <
exec dbms_lock.sleep(12345); 


One that calls this script and has delays:
runPlusTest:
------------

trap "break" INT
myPlusTest &
var=$!
while :
do 
        clear 
        ptree $var 
        sleep 3
done

When runPlusTest is called, a CTRL-C kills the sqlplus started withing myPlusTest

However, if myTest was using a OS command, that would ignore the Ctrl-C and continue processing.
