Configure EMC Storage Plugin for OEM12c

You will have to download the EMC Storage pluging and get it installed in your OEM.
This is a one time activity. Once it is done you can proceed as below for Adding the Target VNX Array to your Grid Monitoring.



1. From the Setup menu, select Add Target > Add Targets Manually.
2. In the Add Targets Manually page, select Add Non-Host Targets by Specifying Target
Monitoring Properties.
3. In the Target Type field, select EMC VNX Block Storage

4. To the right of the Monitoring Agent field, click the magnifying glass icon, and then
select the required agent or agents from the list.

5. Clilck Add Manually.

6. In the Add EMC Symmetrix VMAX page, enter the required properties for the target.
• Enter any string for the Target Name, which is used to identify the target being
created.
• Type Yes to accept the End User License Agreement that is packaged with the
plug-in.
• Enter the path to the directory where the inq utility is located (typically, /opt). Use
quotation marks if the path (such as on Windows) contains spaces. The inq utility
is included in the plug-in download package.
• If you use PowerBroker, enter the PB role that has privileges to run the command
listed earlier.
• Type 0 for normal logging. EMC Support may ask you to change this value to 1 to
help troubleshoot any issues you may have.
• Enter the path to the Solutions Enabler bin directory. Be sure to use double
quotation marks around this path if it contains spaces.
• Enter the EMC Array ID, which uniquely identifies the VNX storage system.

7. Click on Test Connection.

8. click OK and your target will be saved. You can repeat the same for all the arrays in your configuration.

Configure RAC cluster in OEM

Here are the step by step instructions to add a RAC database to 12c Grid. There is a catch in adding Clustered Databases is, when you try to discover (and add) a cluster databases like you do a standalone database, 

12c Grid does not show you an error but the process doesn’t complete. It is because of a missing a required step.

 Lets Start.

Deploy agents on all the nodes.

After all the  agents are deployed  to all nodes, we will add “Oracle Cluster and High Availability Service”.

Select Add Targets --> Add Targets manually

select “Add Targets Using Guided Process” and select  “Oracle Cluster and High Availability Service”.

Select one of the nodes which is part of the your cluster.No need to select all hosts.

Click on Discover Target

If you get an error - "No Cluster Was Found On The Host"

Workaround I: Execute the following commands on all cluster nodes, then try to discover the CRS target from EM console

1. <AGENT_HOME>/agent_inst/bin/emctl stop agent
2. export CRS_HOME=<CRS_HOME>
3. <AGENT_HOME>/agent_inst/bin/emctl start agent

Workaround II: Discovery the cluster target manually by specifying target properties

1. Setup/add targets/add targets manually
2. Add Targets Declaratively by Specifying Target Monitoring Properties
3. Target Type:Cluster
4. Monitoring Agent: Choose one of the nodes of the cluster
5. Click on "add manually"
6. Enter the following details:-
   
       Target Name: <enter the name of the cluster target*>
       Oracle Home: <oracle home of the cluster*>
       Scan Name: <enter scan name*>
       Scan Port: <enter scan port*>
       ONS Port: <enter ONS port*>
7. In the section "Cluster Host and High Availability Services Targets" the node which was chosen will be shown.  Click on "add" and choose the other nodes of the cluster.
8. Click on save

It’ll discover the other nodes, and show you the findings so you may edit them if required. Click “Next”, review and then save the cluster.

 Now we have the cluster information, so we can add our clustered (RAC) database.

Go to “Add Targets Manually” page again, select “Add Targets Using Guided Process” and select  “Oracle Database, Listener and Automatic Storage Manager”.

Now you need to select “cluster” which was set up earlier. Click “Next”.

It will discover database, instances and ASM. Then you need to select the checkboxes of the discovered targets, enter the reqd passwords and  click “Next”. 

You’ll be able to review the result and add the database to EM12c by clicking “Save”. So we successfully added our RAC Databases(s) to EM12c.
