3. user1 .EMP Is a table In PDBI and user2.DEPT is a table in PDB2.

The insert on user2.dept is uncommitted.

The inserts on USER1. EMP were committed when the session inserted a row into user2 .dept.

The inserts on USER 1 . EMP remain uncommitted when the session connected to pdb2.

The insert on user2.dept Is a recursive autonomous transaction by the child session and is committed.

The insert on user2.dept fails because of the active transaction in the parent container.

The inserts on USER1.EMP were rolled back when the session connected to pdb2.

QUESTION 168
Examine these queries and their output:

An online RMAN backup of the CDB was taken an hour before Restore Point R1was created.
