Lois: Hello and welcome back to the Oracle University Podcast. I'm Lois Houston, Director of Innovation Programs with Oracle University, and with me is Nikita Abraham, Team Lead of Editorial Services.

Nikita: Hi everyone! Last week, we looked at two Oracle Database 23ai new features related to Data Manipulation Language, or DML. One was Unrestricted Parallel DMLs and the other was Unrestricted Direct Loads. Do check out that episode if you missed it.

Lois: Today, we have Senior Principal Database & MySQL Instructor, Bill Millar, with us. He's been on several times this season taking us through all the different 23ai new features. In this episode, we're going to ask him about the Automatic Transaction Rollback feature. Hi Bill! What is automatic transaction rollback and why is it an important feature for database administrators?

01:22

Bill: We can now have transactions that are blocking other transactions, depending on some settings, to automatically roll back. It does require some parameters to be set. Rows basically get locked in a single row. Each row is locked based off of what type of activity is being performed on that row, such as inserts, updates, deletes, merge, select for updates.

Nikita: And how were things before this feature?
