The Goal of Monitoring System

#Kscope

EM12c was announced at Oracle Open World, Oct. 2011.

EM12c was Oracle’s answer to business’ reach into Cloud environments, which offers the ability to setup, deliver and manage them.

Administrators, through a single console, can now monitor usage, setup metering, chargeback for users, manage deployed applications, manage issues and link applications to MOS directly.

Enterprise Manager 12c, the Cloud

#Kscope

The full installer (OMS, Agent and Repository) is available for Linux x86-64, Windows, Solaris and AIX.

The installation requires Oracle Weblogic Server 10.3.5, which is included in the package.

Installation does require an Oracle Database on which Oracle Management Repository will be configured. Version 10.2.0.5 and above are supported.

The EM12c manages databases from 9.2.0.8 and above.

The Nitty-Gritty

#Kscope

Installation Rules● The Oracle user does NOT require SUDO privs, (to

put security concerns at ease…) Any account with SUDO privileges can run the root.sh script at the end of the EM12c and agent installations.

● Port configuration in environments with more than one EM, (i.e. running parallel with 10.2.0.5, such as our environment) can run into port conflicts.

The Nitty Gritty, Cont.

#Kscope

As long as the OMS is on its own server and is only used for the OMS repository and/or an RMAN backup catalog repository, individual oracle licensing IS NOT required for the Oracle database utilized for the repositories, (Please see pg. 15 of the following PDF from Oracle.)

Questions revolving dataguard installations, but RAC is clear- you have to pay for RAC installations of EM12c!

Ensure that the SYSMAN account is both unlocked and set to a password that meets the proper requirements, (over 8 characters, mixed case, number and non-ascii characters.)

Know that once the repository is created, there will be sub-accounts supporting the SYSMAN user, (SYSMAN_RO, SYSMAN_MDS, etc…) These are REQUIRED to have the same passwords set through the EMCTL commands as the SYSMAN repository owner.

Auto-deployment is an easy, repeatable process that no longer requires maintenance windows.

No SUDO privilege is necessary for the Oracle user, the root.sh can be run by any account with SUDO privs or by the Unix Admin.

A simple addition to the /etc/hosts file for the agent server and the EM12c host server to each file is all that is required.

If on a Windows EM12c, deploying to a Unix/Linux environment, Cygwin installation/configuration is required.
