How to get all executed SQL queries in ORACLE?

Question

Is possible to find out all SQL queries and their return code, which was executed in Oracle database? Specially I want to get all sql queries which has negative sql code (error).

Thank you for answer.

Answer 1

Everything which was executed? That would require enabling auditing, and fine-grained auditing to boot - and auditing every statement in a database can generate a lot of data.
