• As of December 5, 2019, the Machine Learning (formerly known as Advanced Analytics), Spatial and
Graph features of Oracle Database may be used for development and deployment purposes with all
on-prem editions and Oracle Cloud Database Services.
• See the Oracle Database Licensing Information Manual (pdf) for more details.
• Oracle’s multi-model converged architecture by supporting multiple data types, data models (e.g.
spatial, graph, JSON, XML) and algorithms (e.g. machine learning, graph and statistical functions)
and workload types (e.g. operational and analytical) within a single database.
• Processing and analyzing all types of spatial data in business applications, GIS and operational
systems
• Using graph analysis to discover relationships in social networks, detect fraud, and make
informed recommendations
• Building and deploying machine learning models for predictive analytics
OML , Spatial and Graph is free with the Oracle Database

The following
screen should
appear:
Running an SQL Statement

The white panel below the main title (SQL Query Scratchpad – this name is automatically generated) is an area
known as “paragraph”. Within a scratchpad you can have multiple paragraphs.
Each paragraph can contain one SQL statement or a SQL script.

In the SQL paragraph area copy and paste this code snippet. Your screen should now look like this:

Press the icon shown in the red box to execute the SQL statement….

…and display the
results in a
tabular format:

Using the report menu bar you can change the table to a graph and/or export the result set to a CSV or TSV file.
When you change the report type to one of the graphs, then a Settings link will appear to the right of
the menu which allows you to control the layout of columns within the graph.
Click on the bar graph icon to change the output to a bar graph (see below)

Click on the Settings link to unfold the
settings panel for the graph.
To add a column to one of
the Keys, Groups of Values panel
s just drag and drop the column
name into the required panel.
To remove a column from the
Keys, Groups of Values panel just
click on the x next to the column
name displayed in the relevant
panel.

Changing the layout of the graph
With the graph settings panel
visible:
• Remove all columns from the
both
the Keys and Values panels.
• Drag and drop MONTH into
the Keys panel
• Drag and drop REVENUE into
the Values panel
• Drag and
drop AVG_12M_REVENUE int
o the Values panel

Tidying up the report
•Click on the Settings link to hide the layout controls.
•Click on the Hide editor button which is to the right of the "Run this
paragraph" button.

Now only the output is visible.

Saving the Scratchpad as a New Notebook
The SQL Scratchpad in the previous section is simply a default type notebook with a system
generated name. But we can change the name of the scratchpad we have just created SQL
Query Scratchpad.
•Click on the Back link in the top left corner of the Scratchpad window to return to the OML
home page.

Notice that in the Recent Activities panel there is a potted history of what has happened to
your SQL scratchpad “notebook”.

ADB autonomously and continuously monitors overall system performance
ADB scales CPU-IO resources based on overall workload requirements
• Scaling up autonomously expands CPU-IO resources by up to 3x
Enabled when provisioning new ADB instance or using Scale Up/Down on the Oracle Cloud
Infrastructure Console.
What is “Auto Scaling”

Confidential
ADB is completely responsive to actual usage patterns
Reduces cost of having too many OCPUs just to manage peak traffic load
Auto scaling manages unexpected spikes in workload and ensures consistent performance
BUT…Enabling auto scaling does not change the concurrency and parallelism settings for the
predefined services
Key Benefits of Auto Scaling

1 2 3 4 5 6 7
Auto scaling up as workload increases – ETL, adhoc analytics, data mining
As Workload Increases More OCPUs Automatically Added…

19 - ADB now supports SQL
access to tenancy details

183
When you file a service request for Autonomous Database, you need to provide the tenancy details for
your instance. Tenancy details for the instance are available on the Oracle Cloud Infrastructure console.
However, if you are connected to the database, you can now obtain these details by querying
the CLOUD_IDENTITY column of the V$PDBS view. For example:
...will generate something similar to the following:
How to get the tenancy details for your instance
SELECT cloud_identity FROM v$pdbs;
{"DATABASE_NAME" : "DBxxxxxxxxxxxx",
"REGION" : "us-phoenix-1",
"TENANT_OCID" :
"OCID1.TENANCY.REGION1..ID1",
"DATABASE_OCID" :
"OCID1.AUTONOMOUSDATABASE.OC1.SEA.ID2
",
"COMPARTMENT_OCID" :
"ocid1.tenancy.region1..ID3"}
