Configuring an Exadata (follow up)

Now that we have the exadata and it is up and running, we are working on getting it configured for ease of maintenance.  I know there are some notes from metalink that can be helpful.

The first thing I wanted to do was get the machine (and all the hardware) configured with OCM (oracle Configuration manager).  Like most things with the exadata, there is a special configuration piece for this called the "mass deployment Kit"..  Here is a link for the latest information on it.

 On MOS [ID 1319476.1]

I am still in the process of getting this configured by using the Oracle support Hub (or repeater).  A lot of this information is contained in the PDF mentioned in the My Oracle Support note.  As you can imagine, the exadata is usually installed in a companies core infrastructure, far within any firewalls.  Connecting directly out to the internet isn't always possible, so setting up a repeater (like a proxy) as part of grid (or separately) will help get your configuration information sent up to oracle support.

The second item is Grid/Cloud 12c.  I have to say that I set up Cloud 12c for the exadata about 48 hours after it came out.  It was relatively easy.  You just add the database nodes (and push out the agents), then once the database nodes are done, you use the tools with grid to walk you through discovering all the components (by starting with one of the database nodes). It all worked well, and there are some notes now on this.  Oracle Enterprise Manager Cloud Control 12c Setup Automation kit for Exadata

So the exadata is close to be set up.. I believe setting up OCM is one of the most challenging things.  One of the first steps is to create a spreadsheet with the configuration information.. Following this is the steps from the documentation.  The one complaint I would state is that a lot of the information for the OCM configuration is the same information provided to the "one" script.  I am hoping down the road the ACS group (or whoever does the configuration), also configures OCM, or at least provides the input for it.  OCM isn't necessary, but I think having it configured will save a lot of time when we need to open up an SR.

From the manual......


Use your favorite spreadsheet editor to create the input csv file. To facilitate the use of the input

file, the Mass Deployment document contains a template for you to use in providing the field
values (ocm_companion/distributions/ocm/md/sample_input.csv). See Section 2.4.5 “Input File”
in Mass Deployment documentation for details on the input file format.

Much of the information required as input into Mass Deployment can be retrieved from the
Exadata Database Machine configuration worksheets. Please see Appendix A for examples.

1. Copy/rename the sample_input.csv file (e.g., getinfo_exadata_csi_input.csv). This file
can be used as a template for entering the data for each host on which OCM will be
deployed and/or configured. Add information for all the compute nodes as listed below.

a. Action: Set this column to “get_info” to retrieve information about the state of the
OCM collector in all the Exadata Database (compute node) Oracle homes.

b. Host-Name: Host name of the node.

c. Host-User: OS user that owns the Oracle home.

d. Host-Password: Password for the OS user - set to “__PROMPT__” (two
underscores before and after). See Section 2.4.4 Credential s in the Mass
Deployment Documentation or Appendix B of this document for secure ways of
providing the password. If the same credentials are being used for multiple
hosts, another option is to use a password group name in the password.csv file
as described in Section 2.4.1 of the Oracle Configuration Manager Companion
Distribution Guide .

e. Oracle Home: Oracle Database home location.

f. Db SID: Set the Database SID for the last database host in the input file. This is
required for Mass Deployment to instrument the database for configuration data
collections. This script need only be run on one of the database hosts, but must
be run after the last server is installed.

g. DB Type: Set to 'db' for the last database host in the input file.Specify only for
Install and Instrumentation actions.

h. ML-User: Enter the customer's MOS Account username (email address).

i. ML-CSI: This field holds the Exadata Hardware Customer Support Identifier
(CSI) an can be used in conjunction with the ML-User field to authenticate OCM
uploads. If the CSI is not know, see Appendix B.

j. ML-Pwd: Leave it as blank (should only be used if the CSI is not known).

k. DB-user: Database username required to instrument the database.

l. DB-Pwd: Database user password
