Integrate SQL*Plus Scripts in SQL Developer

I envy my DBA colleagues when they work with the Oracle Database from the command line in an incredibly efficient way.

Using DBMS_DEBUG in SQL Developer

Do you need to debug PL/SQL units in SQL Developer? You can’t get it to work because someone refuses to open TCP ports between your database and your client? No problem. You can still configure the good old DBMS_DEBUG in your SQL Developer. I know it is deprecated since Oracle Database 12c. […]
