The Spotlight user creation script, install_post11gR2.sal, has DROP statements for SYS.EXECUTE_IMMEDIATE and SYS.BUILD_XVIEW.
...
BEGIN
EXECUTE IMMEDIATE 'DROP PROCEDURE SYS.EXECUTE_IMMEDIATE';
EXCEPTION WHEN OTHERS THEN null;
END;
BEGIN
EXECUTE IMMEDIATE 'DROP PROCEDURE SYS.BUILD_XVIEW';
EXCEPTION WHEN OTHERS THEN null;
END;
...
Why do the installation script drop SYS.EXECUTE_IMMEDIATE and SYS.BUILD_XVIEW when Oracle 11gR2 do not contain them?
