Examine the commands executed in the root container of your multitenant containerDatabase (CDB) that has multiple pluggable databases(PDBs):
SQL> CREATE USER c##a_admin IDENTIFIED BY orcl123;
SQL> CREATE ROLE c##role1 CONTAINER=ALL;
SQL> GRANT CREATE VIEW TO C##role1 CONTAINER=ALL;
SQL> GRANT c##role1 TO c##a_admin CONTAINER=ALL;
SQL> REVOKE c##role1 FROM c##a_admin;
What is the result of the revoke command?
