1) About Enterprise Manager Cloud controlOracle Enterprise Manager 12c is a systems management framework consisting of an Oracle database, Oracle WebLogic, a J2EE application, an application development frame work 11g (ADF) administrative Web GUI, server and client side plug-ins, and a client side agent. In the context of Oracle Enterprise Manager, the Oracle database repository is named the “Oracle Management Repository” or “OMR”. WebLogic is the J2EE platform called the “Oracle Management Service” or “OMS”, that runs the Oracle Enterprise Manager 12c J2EE application. The administrative Web GUI is named Oracle Enterprise Manager Cloud Control. The client side agents are named the “Oracle Management Agents” or “OMA”. The server and client side plug-ins share a unique name for the managed product or technology. Monitored hosts are referred to as targets. All of the Oracle Enterprise Manager components are commonly referred to as Oracle Enterprise Manager (OEM) or Enterprise Manager (EM).

Oracle Enterprise Manager (OEM or EM) is a set of web-based tools aimed at managing software and hardware produced by Oracle Corporation as well as by some non-Oracle entities. It is Oracle’s integrated enterprise information technology management product line, which provides the industry’s only complete, integrated, and business-driven enterprise cloud management solution. Oracle Enterprise Manager creates business value for IT by leveraging the built-in management capabilities of the Oracle stack for traditional and cloud environments, enabling customers to achieve unprecedented efficiency gains while dramatically increasing service levels. Enterprise Manager Cloud Control is the new name for what was previously know as Enterprise Manager Grid Control. This article describes the installation of Oracle Enterprise Manager Cloud Control 12c Release 1 on Oracle Linux 6.4.
You must have installed the database home .If you have performed a default database installation you will need to de configure Enterprise Manager Database Control by runnig the following command as the “oracle” user.

There are several Oracle Enterprise Manager 12c design options that can employed depending on the size and critically of your Enterprise Manager enviroment. For example, for evaluations an all-in-one Oracle Enterprise Manager 12c design could be deployed with the Oracle Management Repository and the Oracle Management Service installed on a single Linux node. For small and medium sites a multiple node Oracle Enterprise Manager 12c design could be deployed with the Oracle Management Repository installed on one Linux node, and the Oracle Management Service installed on a second Linux node. If your site's target count requires two Oracle Management Services or Databases, you'll need to deploy a high availability design with two Oracle Management Services with a load balancer, and/or a second Database with RAC for the Oracle Management Repository.

Figure 1 shows a high availability Oracle Enterprise Manager 12c design with the Oracle Management Service on two Linux nodes with a load balancer, a third Linux node with the Oracle Management Repository, servicing various targets. High availability Oracle Enterprise Manager 12c designs are ideal for medium and large sites.

b.      Installation steps

a) Pre-requisites ( Very small size configuration)
OS                          : for Linux Release 6 and above
Database             : 10g and above
OMS                      : Release 12c / 13c

OS Processor    : Min. 2, OS Memory : Min 6GB

Database requirements ( Minimum)
                                : SGA+PGA or memory_target = 3G
                                : Process = 300
                                : shared_pool_size=600M
                                : Redo log size = 300M

See the below Table list for details of requirements for sizing:

Table 1 shows the recommended Oracle Enterprise Manager hardware requirements for an evaluation, small, medium and large deployment.

Deployment Size	OMS Hosts	OMS CPU Cores	OMS RAM	OMS Storage	DB Hosts	DB CPU Cores	DB RAM	All-in-one Install
Eval < 10 agents, < 100 targets, < 3 Concurrent User Sessions	1	2	*4 GB	18 GB	1	2	6	Yes
Small < 100 agents, < 1000 targets, < 10 Concurrent User Sessions	1	2	*6 GB	18 GB	1	2	6	No
Medium >= 100, < 1000 agents >= 1000, < 10,000 targets, > = 10, < 25 Concurrent User Sessions	1	4	*6 GB	18 GB	2 with RAC	4 for each RAC node	8	No
Large >= 1000 agents, >= 10,000 targets, >= 25, <= 50* Concurrent User Sessions	2	4	*6 GB	18 GB	2 with RAC	8 for each RAC node	16	No

* To use BI Publisher add 1.5 GB of RAM.

Table 2 shows the minimum storage requirments for the database server hosting the Oracle Management Repository.

Deployment Size	MGMT_TABLESPACE	MGMT_ECM_DEPOT_TS	TEMP	ARCHIVE LOG AREA
Eval < 10 agents, < 100 targets, < 3 Concurrent User Sessions	15 GB	1 GB	3 GB	Off
Small < 100 agents, < 1000 targets, < 10 Concurrent User Sessions	50 GB	1 GB	10 GB	25 GB
Medium >= 100, < 1000 agents >= 1000, < 10,000 targets, > = 10, < 25 Concurrent User Sessions	200 GB	4 GB	20 GB	100 GB
Large >= 1000 agents, >= 10,000 targets, >= 25, <= 50* Concurrent User Sessions	300 GB	8 GB	40 GB	150 GB

b) Installation steps: All basic installation steps for Linux and Oracle database to be followed as per Oracle recommendations. Here I will show you installation steps for Oracle Enterprise Manager cloud control 12c.

I did below settings in my lab database.

1) Process: ( based on size)
SQL> alter system set processes=500 scope=spfile;

System altered.
2) Memory:
pga_aggregate_target=1G, SGA=2G ( memory_target can be set 3G also)

SQL> alter system set shared_pool_size=600M scope=spfile;
System altered.

SQL> alter system set session_cached_cursors=300 scope=spfile;
System altered.

3) Redo size min 300MB and of 3 members atleast

ALTER DATABASE ADD LOGFILE GROUP 4 ('/u01/oradata/PROD/redo04.log') SIZE 300M;ALTER DATABASE ADD LOGFILE GROUP 5 ('/u01/oradata/PROD/redo05.log') SIZE 300M;ALTER DATABASE ADD LOGFILE GROUP 6 ('/u01/oradata/PROD/redo06.log') SIZE 300M;( dropped others)

Then, Restarted the database.

$

$ ./ runInstaller

Now follow the below steps:

If you have configured internet access on this server, then enter your mail id and support id and password.

Give local directory to install patches.

Note: You must install all pre-requisites RMPs.

Go with Advance installation.

Note: If empty folders not found, above error message will be displayed.

Be sure “agentr5” folder is a blank folder. Otherwise above error message will come.

Weblogic User Name/pwd- weblogic/webl0gic
Nodemanager Use Name/Pwd- nodemanager/n0demanager

( I used above password. The password must meet the requirements)

Select your OMS installation path for EM cloud control.

Here you add your OMS database details. Must check your listener port also.

If your OMS database has EM repository, then remove them as per message shown in the error box. Follow below commands.

- for standalone database
$ emca -deconfig dbcontrol db -repos drop -SYS_PWD <pwd> -SYSMAN_PWD <pwd>

- for RAC database
$ emca -deconfig dbcontrol db -repos drop -cluster -SYS_PWD <pwd> -SYSMAN_PWD <pwd>

If you have not set minimum process value in your OMS database, then above error will come. Now you can increase your process value and bounce the database, then proceed from here.
