As we know Oracle provides several nice tools to debug our PlSql code and even a profiler to get all the details about code execution. But what if you want to use your own debug code and be able to switch it on for specific sessions whenever you want? And I mean, obviously, without changing the code! I’ve seen around some examples in which people use a configuration table to do that: the debug code keeps querying the table and logs the output only if the flag is Y. This way of doing it is absolutely fine and works well but I was looking for something more elegant that does not involve a table. My idea takes advantage of the Oracle application contexts and it’s really simple.
