Monitoring Exalytics (linux 5) with EM13C – Part 1

Oracle Enterprise Manager is an on premise management platform, we decided to investigate the use of 13c and see what benefits we could get by using this to monitor our exalytics system as well as our other Oracle portfolio including premise and cloud applications. There is many blogs on this but I had some interesting challenges that were difficult to resolve that I wanted to share. During this setup, I did reach out to some well-known EM13C experts that I wanted to say thanks to Kellyn - http://dbakevlar.com - @DBAKevlar and Philip - http://redstk.com/blog - @pbedba.  When 13c came out they did not allow you to push or extract an agent that was lets say 12.1.0.5 that you would need if you have linux 5 running.  It was OK if you already had an agent already installed and upgraded to 13 on the OMS server.  This is where the fun began, In this post I will cover the basics as what was needed to be done to extract a 12.1.0.5 agent and install.  Oracle released a few patches for this in the last 6 weeks to help with this which I will also cover. We are installing this on windows 8, First thing we do is download the following:
  • 12c Enterprise database
  • Database templates for EM13.
  • EM13
Ensure your account has administrator privileges.

DB12c Install

Start the installer for Oracle 12c Database. Click next Select install database software only. For this we are selecting single instance database installation. We are installing Enterprise Edition. Remember the password. Enter the paths and click next. We have installed the database. Unzip the database templates for EM to (This will be the location where you have installed the database software, ensure you unzip the templates to the templates folder. C:\app\kt1\product\12.1.0\dbhome_1\assistants\dbca\templates C:\app\kt1\product\12.1.0\dbhome_1\BIN Run dbca.bat as administrator Select next Select advanced mode click next. If you have saved the templates to the correct location you will see the templates in the above screen. Enter your database name and click next. Ensure nothing is selected in screen above and click next. For this example we are using the same password, note your password.     Select create a new listener, and give it a name and the port you want to use.   Select filesystem,Click next.   In the above screen select the following file, which should be where you extracted your templates.: shpool_12.1.0.2.0_Database_SQL_for_EM13_1_0_0_0.sql Click Next      Click Next Click Finish   Database Created.

EM13c Install

Select next Select skip for now, and click next. As I am installing this on my laptop, I have ignore this error. Still works OK J, I have 8gb memory.   Click Yes We are doing simple. Enter your details as well as your host name.   Enter the password you want for your EM, and provide your database connection details. Select next. Click Install. You will see the installation progress.  

Downloading Agent Software

Our Exalytics system we need to install the agent 12.1.0.5, Log into your EM13C., Select Setup/Extensibility/Self Update,   Drill down into the agent software. Select version 12.1.0.5 Click Download At this point I started hitting problems. 13c did not allow you to push to a 12.1.0.5 agent by default, to be able to do this you will need to patch the EM13C. As when you try to export the agent you get an error as below. Download Patch 22741755 and install as per Read Me, remember on windows ensure you do this as Administrator. Once done also verify it is Installed !!! Lets try and export the agent on the host again. Agent Extracted !!! J

Exalytics Configuration

Log onto your ILOM and ensure the SP system identifier is entered. Log onto your exalytics system As Root

Agent Install onto exalytics

Create a directory on the Target: **This is a known BUG (Heartbeat Status : OMS responded illegally [ERROR- Failed to Update Target Type Metadata]) Download Patch
Patch 22581985: 12.1.0.5.0 agent & 13.1 OMS returns ERROR- Failed to Update Target Type Metadata
 
Install it and verify it as per previous patch. We are now ready to Discover the Exalytics system in EM13C.
