Database as a Service
Many Use the Term, But What
is the definition of Service?
Uhm, we’ll just
disregard this
one!

Licensing…
• Licensing- Database LifeCycle Management Pack and Cloud
Management Pack
• Always check with your Oracle Representative if you have any
licensing questions.

Copyright © 2014 Oracle and/or its affiliates. All rights reserved. | 6
No one should have to
take databases down,
perform datapumps, make
tablespaces transportable
and other manual steps.
It’s not a service if you
don’t have features for it.
Database as a Service should be…
User Friendly
Feature Filled
Relatively Simple
Automated

Why Use Enterprise Manager
There are a number of options to automate the cloning process.
• EM offers a single pane of glass approach.
• Simplicity of drop down menus for the DBA
• Self-Service Portal for the Business
• Support of all hardware, all private and public cloud.
• Dashboards to manage all aspects of provisioning, chargeback, resource
management, etc.

We Support it All
A Block is a Block

Chargeback
Keeping
Departments
Accountable
Since 2005 

Cloning Options
• Clone a copy of Production to a Dev or Test Server quickly and easily.
• RMAN, DataGuard, thin clones all available.
• Simple Provisioning of Environments for projects, refreshes, deployments
and requirements.
• Self Service Portal to Ease Demands on DBA group- Enables Users to
request database services.
• Ability to define quotas at environment and at user level.
• Dashboards to manage space, quota, users and environments.

On Premise Cloning in EM13c
• All database targets now have
cloning options in the main
database drop down.
• This does require the DBLM
management pack to use these
features.

On Premise
Cloning
• First Use-Case-
• Full clone of database
• Each clone subsequently in presentation
will perform very similar steps
• Much would be automated, so beneficial to
see detailed out.

Preferred Credentials- A Must
• This is as important for many features, so prepare your environment
and have these pre-set and tested.

Step 1-Source and Destination

Step 2-Storage, DB Name and Security

Step 3- Initialization Parameters

Step 4- Custom Scripts?

Create Now or Schedule?

Step 5-Review

Submit!

Full Clone Now Available!

Simple Clone Management, Too!
Options to Create,
Migrate and Manage
Clones for Any Database
in the EM Environment

Private Cloud
• How Is a “Private” Cloud different from
a “Public” One?
• Management Should be Single Pane
of Glass
• Provisioning Simplicity
• Use Same Agent, but Hybrid

Oracle Public
Cloud
• Sharing of Resources
• Automatic reallocation of resources between
sharded hardware to make workloads from
one system transparent to another.
• Enhanced Performance and Stability
• Simplifies platform and hardware demands

Hybrid Cloud Gateways, (My Setup)

The Oracle Public Cloud High Availability

Converting an Agent to a Hybrid Agent
Just as the name dictates, this is an agent that is both an on premise agent
and serves as a gateway to the cloud.
• Agent should be 12.1.0.5 or 13.1.0.0.0
• Added traffic to the agent, choose wisely.
• As many hybrid agents as you wish for high availability.
• One is primary, rest are secondary.
• If there is outage, secondary takes over, rest are secondary.

Converting Standard Agent to Hybrid Agent
• This is done via an Enterprise Manager Command Line Interface
Command, (EMCLI)
$emcli register_hybridgateway_agent -
hybridgateway_agent_list=‘agentname.com:1830'

Adding the Oracle User to the Sudoers File
• Best Practice also requests that the Oracle OS user on the OPC
compute host has sudoer privileges.
Log into the OPC as the OPC OS user, (sudo power) and add the Oracle
user to the file:
$sudo vi /etc/sudoers

Remove the Requirement for TTY
• Also comment out the defaults for requiring TTY in the sudoers file.
• If there are concerns, there’s only a small advantage of having this one
to not display clear text passwords, but it is a requirement to have this
shut off for DBaaS.

Generating Keys for Preferred Credentials and SSH
• Generate the key for the software owner, (OS User):
$ssh-keygen –t rsa –b 2048
Files will be generated, by default in a .ssh folder:
-rw-------+ 1 oracle dba 1675 Mar 11 15:01 id_rsa
-rw-r--r--+ 1 oracle dba 398 Mar 11 15:01 id_rsa.pub
-rw-r--r--+ 1 oracle dba 3187 Mar 30 08:59 known_hosts

Using SSH Keys with Credentials
• No Need to copy files to
numerous servers and
workstations.
• Values can be pasted into
the UI.

OPC Requirements
• After setting up SSH key authentication between the OMS host and the
OPC, check that you can login:
$ssh oracle@opcHostName
OR
$ssh –i .id_rsa oracle@opcIPAddress
SSH between OPC and On Premise steps are very important, don’t skip!

Manually Adding an OPC Target
• Standard Entries for the addition until you get to the Advanced Settings:
My agent that I
converted earlier to a
hybrid.

Deploy the Agent to the OPC Compute Host
• Job will take some time to run, but ensure you’ve taken the hostname
from the /etc/hosts file for the OPC hostname.
(The Compute information in the OPC interface is sometimes incorrect.)

Gotchas
• OPC Host Name in Cloud Console MAY not match what is in /ect/hosts.
Always use what’s in the hosts file.
• Often had to use IP address, (although you’ll receive a warning during
manual target discovery) when making this choice.
• If a failure occurs, log deployment data is your friend.
• To deploy on two of my cloud compute virtuals, had to perform a “push
from target” deployment to make it succeed, using response file.

PDBaaS
• Database 12c simplifies requirements and
process for cloning.
• Makes consolidation simpler, (unplug,
migrate and plug into new CDB)
• Speeds up process as CDB stays present.
• Special considerations for AWR data.
• This section is from the Self-Service Portal
Perspective.

Why PDB for DBaaS
Self Service driven :
1. Create new PDB
2. Migrate pre-12c DB to PDB
3. Plug a PDB
4. Clone a PDB
