Oracle 12.2 – how to get access to Enterprise Manager 12c Database Express

Today I have built in my OL 7.3 VM two container databases to verify the new feature in the Enterprise Manager 12c Database Express login screen where I can go direct into a container. The benefit is that I don’t have to set a separate port for each pluggable database anymore.

The DBCA has created me a fresh container database called ZH38 and a pluggable database ZHPDB01. I have enable the checkbox to configure EM 12c Database Express for Port 5501. After the database creation was finished, I was able to see the login screen, but the login was not possible. I got an XDB login prompt. SYS, SYSTEM and other users where I tried were not accepted.

I found  the solution in the Database 2 Day DBA Guide – :

After the execution of this command in the CDB$ROOT container, logins into EM 12c Database Express of the CDB$ROOT and the pluggable database ZHPDB01 were possible. No restart of the container database was required. If once set, it works for all existing and new created pluggable databases, the PDB$SEED included.

If you want to disable this access method to a specific pluggable database, execute the command above with the FALSE flag.

How can you find out if the parameter is set? Thanks to my Trivadis collegue Philipp Salvisberg / who has provided me this PL/SQL code:
