EM Express – 12c Edition

Oracle Enterprise Manager Database Express, also referred to as EM Express, is a web-based tool for managing Oracle Database 12c

About license: This tool is free tool with oracle 12c standard or 12c Enterprise edition

To access EM express you need local listener configuration and this will get installed by default when u use DBCA to create database.

In my case I don't have listener so I am creating it from scratch

I registered my database with the newly created listener as follows

in sqlplus
alter system register;

to know the port of your em please run the following query

select dbms_xdb.getHttpPort() from dual;

DBMS_XDB.GETHTTPPORT()

----------------------

SQL> select dbms_xdb_config.getHttpsPort() from dual;

DBMS_XDB_CONFIG.GETHTTPSPORT()

------------------------------

5500

okay to invoke the em express the following is the formart

in web browser https://hostname:portnumber://em/

in my case the following is the example

Note: This em plugin requires flash player. I tried more tough to update my firefox to install flash player.

finally I managed to install through following command

yum install flash-plugin nspluginwrapper.x86_64 nspluginwrapper.i686

here you go first screen
