OEM 13c Step by Step Installation on Windows

In this blog I have explained the step by step installation of Oracle Enterprise Manager 13c on Windows server.

 

Make sure you have sufficient resources on your laptop or server since OEM13c is really very heavy and might slow down performance of your machine if it does not get sufficient food {resources }.

Since I have done installation on my personal laptop so I have mentioned the resource requirement accordingly. So make sure your machine has below listed resources available.

 Minimum CPU, RAM, Heap Size, and Hard Disk Space Requirements Per OMS for Simple Installation

   Simple Installation
Deployment Size Evaluation or Simple
Configuration 1 OMS, <100 Targets, <10 Agents, <3 Concurrent User Sessions
CPU Cores/Host

(Can be shared with other processes)

2
RAM11The physical memory mentioned here includes .5 GB of RAM required for Oracle BI Publisher. At the time of installation, if you choose not to configure Oracle BI Publisher, then the actual physical memory required can be .5 GB less than what is mentioned here.

(With Oracle BI Publisher and JVMD Engine)

10 GB
Hard Disk Space

(With Oracle Software Library, Oracle BI Publisher, and JVMD Engine)

24 GB
Temporary Directory Hard Disk Space 10 GB
Oracle WebLogic Server JVM Heap Size 1 GB

I am assuming you already have a database created for your OEM. In my environment I have 12C database created.

Step 1: Download the software. {there are 5 files}

http://www.oracle.com/technetwork/oem/grid-control/downloads/oem-windows-2823282.html

Step 2: Run the installer

It will run for sometime and you can monitor the progress.

image2

Once the Installer is finished, it run the prerequisite system compatibility test to start the setup.

image3

Step 3: Enter your MOS account details (optional), if you want to receive security updates from Oracle.

image4

Just a warning will be displayed if you skip your “Support Details” part, you have to confirm that you do not wish to receive updates.

image5

Step 4: Software update search. It is recommended to run this step to ensure your environment is ready for this installation.

image6

If your machine is having all the updated required softwares it will prompt “No updates found”

image7

Step 5: Prerequisite Check. It will run a check to ensure you have sufficient resources available.

{Like in my case I got warning for in-sufficient RAM minimum required was 10 Gb and I had 8Gb of RAM, still I decided to continue with Installation. I was crazy to test this new release and lazy enough to increase my machine’s RAM to 10Gb.}

image8

Click NEXT to continue with Installation.

Step 6: Installation Type. {Simple or Advanced}

If you are already familiar with previous releases and are EM DBA you can go for “Advanced” option.

image10

Step 7: Setting up Installation directories. Here you have configure you Middleware Home, Agent Base Directory and Hostname.

image11

Step 8: Set Administrator Password and put your database connection details.

[Informational message will pop-up with recommendation to setup AL32UTF8 character set for EM Repository database.]

image12

Click OK, it will execute some prerequisite checks.

image13

In next few steps you will be prompted for mismatch of you database settings if they already do not match with the recommended setting for OEM13c installation.

Prompted to check “optimizer_adaptive_features” parameter

image14

Prompted to check “parallel max and min servers” parameter

image15

Prompted to check “shared_pool_size” & “session_cached_cursors” parameter

image16

Step 9 :  Configure Software Library  and Enable BI Publisher.

OEM13c gives you option to configure and enable “BI Publisher” during Installation itself.

image17

Step 10: Review all details entered in all previous steps.

image18

image19

Step 11: Start the installation. 

[Now if you are installing it on your laptop with insufficient resources just like mine 😉 RAM 8Gb ,  believe me installation is going to take more than 4  hours it happened with me. So if you do not want to get irritated while setting this up make sure you have a very good machine with you for your installation ]

image23

Once the Installation is finished, it will run a clean-up process.

image24

Now you are ready to use your OEM13c.

EXCITED… Believe me I was  very much eager to start using it. I have put some more screenshot of the “Login Console, Welcome Page, Incident Manager etc.. “ check out below.

  1. it’s good one.

    At step 7: you have installed Weblogic Already or it’s just setting up path and it will installed automatically while finishing setup?

  2. works fine, just follow the steps.
    thanks

  3. is weblogic server is mandatory for installation of oracle em 13c?

    • Yes, Weblogic is responsible for your console. so there are two ways, either you can install weblogic on your own before installing OEM or it will be installed in setup itself if not already on your system.

      Thanks

  4. how to install in a windows server whit oracle database 11g

  5. Deepak,
    MGMT$TARGET views does not exist in my OEM database after installation. What could have gone wrong?
    Please help!!
    Thanks,
    Sriram

    • Hi Sriram,

      Is this the fresh installation you have done or was it the upgrade. Please specific the upgrade path you have followed in-case you have performed the upgrade.

      Thanks
      Addks

  6. This is fresh installation deepak.

  7. Was your installation ever got successful without any failure during installation process. As you mentioned “MGMT$TARGET” this is quite weird and never happened with me and not even heard that installation got successful and “MGMT$TARGET” view does not exists.

    If your installation got successful, were you even able to get anything, as basic information about all your targets is stored in “MGMT$TARGET” view only. Did you open case with MOS for this.

    Regards
    ADDKS

  8. Hi Deepak,

    On windows-10 I have created 12102 database using EM13101 template and installed EM13101(software ONLY, because by using simple and advance options oms configuration fails at 60%, according to oracle it was hitting a bug and recommended to install only software and configure it later).

    Now how can I manually configure OMS on that EM13101 software?

    Thx in Advance

    • Aakash, apologies for late reply I was on vacations. You can check “https://oracle-base.com/articles/13c/cloud-control-13cr1-installation-on-oracle-linux-6-and-7” blog by Oracle Guru, he has explained very well how you can configure OMS after software only installation.

      Thanks
      Deepak

  9. I follow you’s sop install fished oem 13c, and install one agent windows, but oem not show host?
    how to fix ?

    • Did the installation of agent was successful. Did you check the output of “emctl status agent”. Make sure the root.sh command is run after installation. Also once the command is executed “execute “emctl config agent addinternaltargets”. You can also verify the targets by running “emctl config agent listtargets” or in targets.xml file under your agent_inst home.

      Regards
      Deepak Sharma
