This presentation addresses and tries to provide a reasonable answer to the rather common question: "Why should we still use an Oracle Database?", which more often than not is raised by management, but in the presence of more and more "alternative solutions", also by non-Oracle database administrators who are looking to solve a particular problem. This is the first presentation of my "Oracle Fundamentals" presentation series. Note that slide 35 (of 38) is outdated and should not have been included. Unfortunately, SlideShare does not allow for re-uploads anymore and hence, I will leave it in for now.

Oracle Scales in Many Directions and Ways

14. Copyright © 2019, Oracle and/or its affiliates. All rights reserved. |
Oracle Sharding
• Horizontal partitioning of data
across up to 1000 independent
Oracle Databases (shards)
• Shared-nothing HW architecture
– Each shard runs on commodity server
– No shared storage
– No clusterware
• Data is partitioned using a sharding
key (i.e. account number)

Another, integrated and established way to deploy the Oracle RDBMS

Oracle Sharding
An Extension of the Oracle Database; same Oracle features
that you have with the database work with Sharding
• Benefit of SQL, PL/SQL and ACID
• Advanced Security
• Partitioning
• Maximum Availability Architecture
Intelligently partitions data and workload across N number
of discrete Oracle databases that do not share hardware or
software
Automates end-to-end life cycle management
• Enables automatic partitioning/replication, elastic
scaling, rebalancing, data-dependent routing for
single-shard and cross-shard queries
A complete platform for a Sharded Database

Oracle Database Sharding – Benefits
Linear Scalability
Add shards online to increase
database size and throughput.
Online split and rebalance.
Extreme Availability
Shared-nothing hardware
architecture. Fault of one shard
has no impact on others.
Geographic Distribution
User defined data placement for
performance, availability, DR or to
meet regulatory requirements.

Structured Query Language
(SQL)
• Oracle supports ANSI
standard SQL
• Has extensions to the SQL
language for features that
are not included in ANSI
standard.
Transactions
• Supporting transactions
means the database
ensures the A.C.I.D.
• A.C.I.D. à
Atomicity, Consistency,
Independence, Durability
Programmable
database features
– Stored Procedures &
Triggers
– Oracle PL/SQL
18
Multiversion
Read Consistency
• The data returned by a
query is committed and
consistent for a single
point in time.
Nonblocking queries
• Readers and writers of
data do not block one
another.
Non-escalating
row level locking

Benefit from Cloud Sizing
All workloads exhibit variation – “normal” to “peak”
• Annual/quarterly/weekly/daily seasonal variations
– Retail/other seasonal transactions,
periodic reports and compliance, full backups
• But also intraday variation
– End-of-day reports, analytics workloads, day/night (e.g., lower daytime workload on sparsely
populated landmasses/Pacific Ocean), incremental backups
• On-premises common to see “peak” sized “2x normal”
– If 16 cores are “normal”, the system may get sized with 32 cores
• On cloud, it is safe to provision for normal workloads and burst up as needed
25

25. Copyright © 2019, Oracle and/or its affiliates. All rights reserved. |
Production (Prod) Workload Sizing
• On Premises (and Non-metered)
Size for the peak, plus additional
buffer = lots of idle CPU
26
+ BufferPeak
CPU Usage
• Use hourly bursting for peak
• OCPUs available through
bursting – no need to add Buffer Normal + Hourly Bursting

DR
• Size for redo apply CPU Usage
• Add OCPUs (expansion / burst) for DR

• Oversubscribe using Multitenant
• Size for development
– Vastly underutilized except for performance testing

Oracle Real Application Clusters (RAC) in SE2 De-Support
Oracle Standard Edition “Sound Single Instance Foundation”
• Effective with Oracle Database 19c
• Oracle RAC in Standard Edition 2 (SE2)
• will not be supported anymore.

29. Copyright © 2019, Oracle and/or its affiliates. All rights reserved. |
Long Expected Development
• SE2 Socket requirements are hard to meet as hardware evolves.
• SE Oracle RAC has seen diminishing demand with increased high
availability requirements, as SE does not provide the full set of HA
capabilities available in the Oracle Database Enterprise Edition.
• A migration to (the Autonomous Database in the) Oracle Cloud is an
attractive upgrade path for customers – financially and functionally.
– Autonomous Database provides EE features at a compelling conversion rate.

Move SE Oracle RAC to the Autonomous Database
• Convert your SE Oracle RAC Databases into an Autonomous Database
• BYOL:
– Conversion Ratios for Oracle Database Standard Edition , Oracle Database Standard, Oracle
Database Standard Edition 2 (Oracle Database Standard Edition Programs):
• For 1-8 OCPUs of Oracle Autonomous Transaction Processing Cloud: For each supported Processor
License of Oracle Database Standard Edition Programs (where a Processor is defined as equivalent
to an occupied socket), you may activate up to 4 OCPUs of the BYOL Cloud Service.
• For 1-8 OCPUs of Oracle Autonomous Data Warehouse Cloud, for each supported Processor License of
Oracle Database Standard Edition Programs (where a Processor is defined as equivalent to an occupied
socket), You may activate up to 4 OCPUs of the BYOL Cloud Service.

Use Autonomous Database for SE Oracle RAC Databases
• SE does not provide all of the HA capabilities available in the Oracle Database
• Autonomous Database
– uses a RAC-enabled Oracle Enterprise Edition by default
– includes an availability promise based on a MAA-compliant setup
• https://www.oracle.com/database/autonomous-database/think-autonomous.html
– SLA guarantees 99.995% reliability and availability,
which minimizes costly planned and unplanned downtime to less than 30 minutes a year.
