OCI - MAIN MILESTONES
Oracle Cloud Infrastructure – OCI
• Launched as Oracle Bare Metal Cloud
• Announced at Oracle OpenWorld 2016
• Changed to OCI in January 2017
• Evolved to 2nd Generation and announced at Oracle OpenWorld 2018.

ORACLE CLOUD INFRASTRUCTURE
https://blogs.oracle.com/cloud-infrastructure/introducing-the-generation-2-cloud-at-oracle-openworld-2018

OCI
COMPARTMENTS
• Compartment is a collection of related resources (instances, VCNs, block volumes, etc)
• Can be accessed by groups that have have been given permission by an administrator
• When you sign up for OCI, Oracle creates your tenancy, which is the root compartment
• You can create compartments to organize and isolate your cloud resources:
• DEV_COMPARTMENT;
• QA_COMPARTMENT;
• PROD_COMPARTMENT.

OCI
KEY CONCEPTS
• Region is a localized geographic area (Disaster Recover)
• Availability Domain is one or more data center located within a region isolated from each other
(High Availability)
• Virtual Cloud Network (VCN) is a virtual version of a traditional network, with subnets, route
tables and gateways
• Instance is a compute host
• Shape specifies the number of CPUs and amount of memory
• Block Volume is a virtual disk
• Object Storage is a storage architecture to store and manage data as objects
• Oracle Cloud Identifier (OCID) is an Oracle-assigned unique ID for each resource in OCI

OCI

NETWORKING SETUP FOR DB SYSTEMS
Two Options
• Public Subnet can be useful for proof-of-concept or development work. Use if you have services that run only on a
public network and need to access database.
• Private Subnet recommended for a production system. Cannot be reached from the Internet.

OCI
DATABASE ON CLOUD
One Million Question
• Should I move my database(s) to Cloud?

OCI
DATABASE ON CLOUD
• It Depends!
• Are you planning to move your application ecosystem to cloud?

OCI
DATABASE ON CLOUD
Big Challenge when moving databases to Cloud
• Traffic between Database tier and Application tier
• Moving your application ecosystem along with database you can benefit from Cloud features/advantages
• If some piece/part of your application remains in On-Premises DataCenter, even with FastConnect you can expect
some increased response time.

OCI
DATABASE SIZING
Most Common Question
• Should I provision resources using the same sizing as I have in On-Premises?

OCI
DATABASE SIZING
As always, it depends!

OCI
DATABASE SIZING
Some Questions
• Actually, do you have waits for CPU?
• If yes, how long are the waits? Those waits impact business?
• If yes, maybe your CPU is under pressure
• If no, probably you have spikes
Let’s assume as example that you have spikes in CPU usage

OCI
DATABASE SIZING
How much pain are you willing to tolerate?

OCI
DATABASE SIZING
No pain! (No wait!)

OCI
DATABASE SIZING
Some pain is tolerated!

OCI
DATABASE SIZING
How measure CPU usage?
• If you have Diagnostics Pack: DBA_HIST_ACTIVE_SESS_HISTORY (ASH)
• If you don’t, STATSPACK or any external OS monitoring tool

OCI
DATABASE SIZING
DBA_HIST_ACTIVE_SESS_HISTORY
• Query for how many sessions are waiting for CPU (WHERE session_state = 'ON CPU' )
Main Issue
• ASH is sampled only when there is activity
• Some periods of time without activity do not generate ASH samples
How to avoid issues when using ASH to sizing CPU usage?
• ASH Standardization!
• Jorge Barba from Acenture Enkitec Group:
https://jorgebarbablog.wordpress.com/2016/12/21/how-to-standardize-ash-data-for-sizing/

OCI
DATABASE SIZING
With ASH data standardized, should I use MAX values?
• Only if you cannot tolerate any pain!
Can I use AVERAGE?
• No! You can have some spike periods much biggest than AVERAGE.

OCI
DATABASE SIZING
What I can do to find out the “Magic Number”?
• You can use percentiles.
Percentiles in One Hour
• 97th percentile: longest wait is 1.8 min in 60 mins
• 95th percentile: longest wait is 3 min in 60 mins
https://jorgebarbablog.wordpress.com/2016/12/27/sizing-post-3-understanding-percentiles/

OCI
DATABASE SIZING
How is the appropriate percentile for my database workload?
How much pain are you willing to tolerate?

OCI
DATABASE SIZING
Memory
• Should be the same. Check the Shapes available to fit your need
IOPS
• AWR:
• physical read total IO requests
• physical write total IO requests
I/O Throughput
• AWR:
• physical read bytes
• physical write bytes

OCI
CHOOSING A METHOD
https://docs.cloud.oracle.com/iaas/Content/Database/Tasks/migrating.htm#ChoosingaMigrationMethod

OCI
CHOOSING A METHOD
1. Database version of your on-premises database:
• Oracle Database 19c
• Oracle Database 12c Release 2 version 12.2.0.1
• Oracle Database 12c Release 1 version 12.1.0.2
• Oracle Database 12c Release 1 version lower than 12.1.0.2
• Oracle Database 11g Release 2 version 11.2.0.3 or higher
• Oracle Database 11g Release 2 version lower than 11.2.0.3

OCI
CHOOSING A METHOD
2. For on-premises Oracle Database 12c Release 2 and Oracle
Database 12c Release 1 databases, the architecture of database
• Multitenant container database (CDB)
• Non-CDB
3. Endian format (byte ordering) of your on-premises database’s
host platform
• OCI Databases use the Linux platform, which is little endian

OCI
CHOOSING A METHOD
4. Database character set of your on-premises database and the
OCI Database
• Some migrations methods require that the source and target
databases use compatible database character sets

OCI
CHOOSING A METHOD
5. Database version of OCI Database you are migrating to
• Oracle Database 12c Release 2
• Oracle Database 12c Release 1
• Oracle Database 11g Release 2
For Oracle Database 12c Release 2 and Oracle Database 12c Release 1 databases:
