Discovering Exalytics in EM13c

In one of my posts I installed and set up EM13c and installed an agent onto the Exalytics system, we will now discover the system in 13c.

Select targets/Systems

 

Select Add/Exalytics System

Enter the Machine Name, Agent, Platform, Deployment Type, username, Password, IP Address, ILOM Details

Click Next


 

 

Click Add Targets

Log onto the ilom

 

Select a free alert and click edit

In this screen we will enter the details where the agent is running, so that the ilom can send alerts.

Verify the Compute Node ILOM SNMP

  1. Log onto the host running the agent

Log onto the ilom , and see the event log:

Now check in the EM console if we can see the event id.

Clear in cloud control.

Monitoring Exalytics (linux 5) with EM13C – Part 1

Fresh Install of EM 13C and the challenges of pushing a 12.1.0.5 agent for linux 5 from EM13C.

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.

 

TimesTen Tip IPCS

So you are restarting the timesten daemon and for some reason, you are getting an error when you try to restart.

Whenever you stop the process, always check it has released the process and memory.

To check if it has stopped:

We can see from the above it is still attached, First try the stop command again, if that fails, run the ttstatus command to find the pid.

You can see there is no connections to the data store.

Kill the pid’s via the kill command. You should be OK to start it now.
