PLW-06015: parameter PLSQL_DEBUG is deprecated

Toad for Oracle - Beta
1

Enable PL/SQL Warnings:

ALTER SESSION SET PLSQL_WARNINGS = 'ENABLE:ALL'

Then compile source in Debug mode.

This results in the following warnings:

SELECT text FROM user_errors;

PLW-06013: deprecated parameter PLSQL_DEBUG forces PLSQL_OPTIMIZE_LEVEL <= 1
PLW-06015: parameter PLSQL_DEBUG is deprecated; use PLSQL_OPTIMIZE_LEVEL = 1

Looks like PLSQL_DEBUG has been deprecated for a long time:

The PLSQL_DEBUG parameter is deprecated. It is retained for backward compatibility only.

I guess this parameter is set by TOAD?
