Dear Readers,
My name is Franz Devantier, creator of this blog. I am an Oracle Certified
Professional (OCP DBA 11g) Security DBA.
I will be sharing with you the basic duties of an Oracle DBA, and also
some of the undocumented, and not so well known tasks.
I will make a deal with you: If you refer me to a company that needs
database support, from a few hours per week to full time, and I am able to sign
a contract with them.
Then I will give you 10% of the monthly
contract or deal price every month. When
the contract ends, and we re-sign the contract, I will again give you 10% of
the monthly contract price. This will go
on until the company no longer employs or contracts me or my agents to look
after their databases.
I can do this, because that 10% is my
marketing budget. When we re-sign the
contract, in the future, it may depend on you giving the thumbs up again, and
that is worth 10% of the monthly contract price, to be given to you as
commission.

Before
You Begin
When
the Exalogic Control is initiated and started by the Exalogic Configuration
Utility (ECU), then a default root user account is created.
This
root user must then create the Exalogic Systems Administrator in Exalogic
Control. When you create a user, the
username and password are imported from the local directory on the VM hosting
the Ops Center Enterprise Controller. To
make things work you must first add a user name to this local directory, before
you can add it as a local user in Enterprise Manager Ops Cneter.
To
create a local user on the VM hosting the Ops Center Enterprise Controller, you
need to complete a number of steps.
->
firstly you need to run the following command to create a local user.
For
example:
#
useradd –d /export/home/ELAdmin –s /bin/bash –m ELAdmin
->
The second step is to create a password for the newly created local user
ELAdmin.
For
example:
#
passwd ELAdmin
->
Repeat this procedure to create other local users, such as CloudAdmin, User1,
User2, and etc, before adding them in the Exalogic Control BUI.
Creating
the Exalogic System Administrator
There
are a few steps to complete to create the Exalogic Systems Administrator role
in the Exalogic Control.
1.
Use the root user account to log in to the BUI of the Exalogic control:
http://<EMOC_IP>
<EMOC_IP>
is the IP address that was assigned to the Enterprise Controller when running
ECU to configure and bring up Exalogic Control.
Unless it has been changed, use the password “ovsroot”.
The
URL is redirected to this URL:
https://<EMOC_IP>/emoc
2.
On the home page, click the “Administration” option on the left navigation
pane.
3.
Under Enterprise Controller, click on the “Local Users” option. The Local Users page is then displayed.
In
order for a user to be created in Exalogic Control, make sure that the user
exists on the virtual machine, where Enterprise Manager Ops Center Enterprise
Controller is running.
4.
Under the Users and Notification Profiles, click on the “Add User” icon. You could also click “Add User” on the
“Operate” pane. In both cases the Add
User screen is displayed.
5. In the User Name
field enter the username, which you have validated was created on the OS
environment. For example ELAdmin.
6. Select the
“Exalogic Systems Admin” role, the “Management Admin” role, and the “User
Management Admin” role from the list of Available Roles on the left hand side,
and move them to Selected Roles on the right hand side, by clicking the right
arrow.
The “User Management Admin” role will allow the Exalogic
Systems Administrator to manage users.
7.
Click on the “Add User” button at the bottom of the screen. The Exalogic Systems Administrator has now
been created. You don’t want more than
one or two users who are created with the Exalogic Systems Administrator role.
8. Log out as the root user, and you are done.
