Installing OEM 13c and deployment of targets on Oracle Enterprise Linux

This is a step by step document of installing OEM 13c Release 2 and how to deploy targets in Linux environment.

Note:Oracle Database 12.1.0.2 is already installed, the steps for which are not covered here.

Download OEM 13c from edelivery website https://edelivery.oracle.com

Unzip the files.

[oracle@oem13c oem_binaries]$ chmod u+x em13200_linux64.bin

[oracle@oem13c oem_binaries]$ ./em13200_linux64.bin

[root@oem13c middleware]#

Login to the OEM url using sysman user

Create the env variable in the OMS host.

[oracle@oem13c oem]$ cat oem.env

export OMS_HOME=/u01/oem/oracle/middleware

export AGENT_HOME=/u01/oem/oracle/agent/agent_inst

[oracle@oem13c oem]$

 Next, we will push the agents to the respective hosts.

Click on "add target manually" as show above in the screenshot.

Next,

Click on install agent on host

Click on "+ Add" button and provide the required session name of your choice

Choose the host which should have the fully qualified name and the specific platform

Note: The host to be added should be reachable from OMS host. Thus before proceeding, check if  you are able to do a telnet

telnet oem13c.localdomain 3872--check if the client server is able to telnet to the oms server

Trying 192.168.56.6...

Connected to oem13c.localdomain (192.168.56.6).

Escape character is '^]'.

^CConnection closed by foreign host.

Once the deployment completes, we will be able to see the added host.

Till now, only the host monitoring has been enabled. OEM gives the advantage of adding the different types of targets for monitoring. Here, we have shown only the database monitoring part. 

Click on Add using guided process

Choose the respective host

provide the dbsnmp credentials

As we can see now that database is now available

For adding Oracle E-Business Suite as the target, we need to install the AMP plugins first, for which we need to follow the note:

• Getting Started with Oracle Application Management Suite for Oracle E-Business Suite Release 13.1.1.1.0 (Note 2045552.1)

This concludes installing OEM 13c and deploying targets in OEM. In the further posts, i will cover how to create metrics extensions and how to create incident rules in OEM 13c.

Hope, this post will help someone.
