0. Environment

Version		: 12.2.0.1.0
OS    	 	: Red Hat Enterprise Linux Server release 6.8
IP     		: 192.168.2.101
CDB NAME	: CDB2
PDB NAME	: PDB4


1. Introduction

Oracle Enterprise Manager Express is a Web-based interface for managing an Oracle database 12c. 
Used to perform basic administrative tasks such as 

- Managing users
- Managing memory
- Managing storage
- Managing database initialization parameters
- Monitor performance
- View SQL Tuning Advisor information
- Verify status information container database and pluggable databases.


2. Verify OEM Express already configured or not for CDB2

If returned port number is 0, it means that EM Express is not configured for that particular container.
