Database as a Service

Many Use the Term, But What is the definition of Service?

Uhm, we’ll just disregard this

one!

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 AllA 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:

$ssh oracle@opcHostNameOR$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


Self Service Options for Empty or Populated PDB
