Oracle Enterprise Manager (OEM) 12C (12.1.0.1 Cloud) #em12c : Overview and Installation

After i (Internet) and g (Grid) it’s now turn of c (cloud). As Oracle Enterprise Manager (OEM) 12c is now available, this post covers key points including software and documentation link to install/configure OEM 12c

  • You can download Oracle Enterprise Manager (OEM) 12c from here
  • Documentation for OEM 12c is available here

OEM 12c Component

OEM 12c is more or less similar to its predecessor OEM 11g with exception of Management Plug-In (all components to be managed by OEM 12c like database, fusion middleware and so on will have respective plug-in so if you upgrade component that you are managing then simply upgrade management plug-in for that component)

a) Management Repository
b)  Management Service
c) Management Agent
d) Management Plug-In
e) OEM Console

Key Points for OEM 12c

1. Sun JDK 1.6 patch 24 is required which can be installed in advance or OEM 12c installer installs by default (if JDK 1.6 is not available). JRockit JDK is NOT supported with OEM 12c (as of 3 Oct 2011)

2. When you install OEM 12c , installer creates default domain name GCDomain. To change domain name during installation use parameter WLS_DOMAIN_NAME for ex.

runInstaller WLS_DOMAIN_NAME=oem12c

3. There are two options for OEM 12c installation
a) Simple – Default settings
b) Advanced – option to provide weblogic server details, database data file and tablespace customisation or custom port selection.

4. OEM 12c installer creates instance directory gc_inst in Middleware Home (MW_HOME).

5. Instance directory gc_inst contains WebLogic Domain Directory (user_projects/domains/GCDomain) and Oracle HTTP Instance (WebTierIH1)

6. OEM 12c Installer creates WebLogic domain with Admin Server (EMGC_ADMINSERVER) and Managed Server (EMGC_OMS1). To know more about WebLogic Domain, Admin, and Managed Server click here

7. OEM 12c cloud control console (UI) is accessible only on HTTPS (SSL). To access console on HTTP (non SSL) use

emctl secure unlock -console

8. Default URL to access EM 12c is https://serverName:[EMGC_OMS1_SSL_PORT]/em (Note https in URL)

After logon (weblogic/<password>) You should see screen like below

Thanks for posting Atul, useful information in your post.

I’d be interested in any review that you do on the monitoring and management of OID/OAM using EM12c

Thanks,
Alan…

@ Alan,
Nice to hear from you, monitoring IDAM (OID/OIM/OAM) 11g via OEM 12c is good idea. I am currently working on Fusion Apps and will pick monitoring after that.

Hope you have already configured 11gR2 RAC monitoring via 12c :)

@ Trung Phan,
I am not clear what do you mean by “can i access Mgmt Repository Database to get info for other purposes”

Do you mean you wish to use Mgmt Repository for other purpose like BI ?

Trung Phan says November 30, 2011

Dear Atul,

EM12c has new feature Chargeback (Cost center, Charge plan).
In term of Billing, if i want to access to em12c Management repository database from our existing billing system (third party or home-grow), is it supported?

other case of BI.

as i understand then em12c Management repository database is restricted database type, if i assumed that it supports the above as i mentioned then do i need to buy license of oracle DB for Mgmt repository to access for other purpose of billing or BI?

Thanks, Trung.
