Is there a way to see wheter index being executed or not by
query except EXPLAIN PLAN ?

I h've to check at runtime because SELECT is executing by application.

hello

Run the application

Then identify the SID and SERIAL# of the running session of your application

Then execute the following command

Begin
dbms_system.SET_SQL_TRACE_IN_SESSION(<SID>,<SERIAL#>,TRUE);
END;

the above statement will trace your application, once the application is done

run the follwoing

Begin
dbms_system.SET_SQL_TRACE_IN_SESSION(<SID>,<SERIAL#>,False);
END;

This will end the trace.

find the newly created file in the UDUMP directory

Then ananlyse the file using TKPROF

tkprof tracefile outputfile analyze=scott/tiger

or better look into tkprof to find out what other switches you wnt to use

PS
You can use Oracle Enterprise Manager to accomplish the same and READ the execution plan online.. other third party tools accomplish the same
