Install Oracle Enterprise Manager Cloud control 12cR4

on OEL 6.5

In the article you will have a look at the guidelines and steps to install

OEM Cloud Control 12cR4 on Oracle Linux 6.5 X86_64. You will have a glimpse

at how to configure OEL 6.5 for OEM CC 12cR4 installation. Oracle 12.1.0.1

database is used as an Oracle Management Repository (OMR) database. I will

provide pointers to MOS or Oracle Documentation for the supported OS and

Repository database versions.

The environment I use is an Oracle VM VirtualBox running on a MS Windows host

OS with OEL 6.5 x86_64 guest OS. I am not going to describe neither details

of configuring the Oracle VM VirtualBox nor details on installing OEL 6.5 and

installing Oracle RDBMS binaries 12.1.0.1 and databases. More information

about the latter can be found here. I would like to point out that you need

to pay attention for the hardware and software requirements described here.

My VM running the guest OS is configured with 8GB RAM and 80GB of disk space.

The latter is to accommodate the disk footprint for Oracle binaries, stage

area and Oracle databases. If you need to add disk space to already

configured VM look at here.

Select a supported OS and install supported Oracle database for repository.

MOS maintains a list of certified platforms and products for a product. For

OEM CC 12cR4 you will have to look at:

1. Certified OS for installation

2. Certified Oracle database for repository

3. Certified targets

You can obtain the information from MOS.

For OEM CC 12cR4 on OEL 6.5 I have the following information.

I installed the OEL with all options and created the following databases

1. EMREP version 12.1.0.1 serving as OMR

2. DCB12C 12.1.0.1 used as a CDB for testing purposes.

3. Downloaded OEM CC R4 from OTN and staged it in the Guest OS.

Before you start installing OEM CC 12cR4 I strongly recommend browsing the

Oracle documentation here and here to have an idea what you are expected.

The article will skip and will not cover the following:

1. Installing 12.1.0.1 binaries and

2. Creating EMREP OMR database.

3. Creating CDB12C CDB database

The OMR database can be set in advance with the following init parameters

alter system set processes=500 scope=spfile;

alter system set session_cached_cursors=500 scope=spfile;

alter system set shared_pool_size=300000000;

alter system set memory_max_target=1000m scope=spfile;

alter system set db_securefile=PERMITTED scope=both;

alter system set memory_target=1000m scope=spfile;

Installing the oracle-rdbms-server-12cR1-preinstall package using the command

yum install oracle-rdbms-server-12cR1-preinstall greatly simplifies the

configuration.

Installing OEM CC 12c R3

1. Create a .bash_profile as specified in the Appendix A

2. Launch the runInstaller and de-select receiving security updates from

MOS.

3. Select Skip

4. Let the prerequisites checks completes.

5. I selected create a simple installation

6. Select the binaries location.

7. Specify the sysman administrator user password, database configuration

details and software library location.

8. Fix the issue if you have not done it yet.

9. If you have not changed some of the OMR parameter you can do it now by

letting the installer do it for you or after the installation.

10. If you have not set the init parameter initially before the

installation you are provided the following options. Click OK in order

to set the parameters later.

11. Review and click install.

12. This is the whole info for you to review.

13. Wait for the installation to complete.

14. If you face the following issue manually start OMS.

[oracle@oel65 bin]$ ./emctl stop oms -all

After manually starting OMS retry the operation. The content of the

start and stop scripts are in Annex A.

15. Wait until you are asked to run the scripts as root.

16. Run the script as root.

19. Verify that you can login to the Administration Console.

20. Verify that you can login to the OEM CC 12cr3 console.

21. Create scripts for OEM startup and shutdown

[oracle@oel65 ~]$ cat startOMS.sh

export OMS_HOME=/u01/app/oracle/product/12.1.0/em12cr4/oms/oms

export

AGENT_HOME=/u01/app/oracle/product/12.1.0/em12cr4/agent/core/12.1

.0.4.0

$OMS_HOME/bin/emctl start oms

$AGENT_HOME/bin/emctl start agent

[oracle@oel65 ~]$ cat stopOMS.sh

export OMS_HOME=/u01/app/oracle/product/12.1.0/em12cr4/oms/oms

export

.0.4.0

$OMS_HOME/bin/emctl stop oms -all

$AGENT_HOME/bin/emctl stop agent

[oracle@oel65 ~]$

22. Modify the sudoer file

Set sudoers access for oracle and grid in /etc/sudoers

oracle ALL=(ALL) ALL

grid ALL=(ALL) ALL

23. This concludes the OEM CC 12C R4 installation.
