3 – Cross Region
DataGuard

Disaster recovery terminology
Peer Databases: Two or more databases that are linked and replicated
Consist of a Primary database and Standby (copy of the primary) databases
Primary or Source Database: The main database that is actively being
Standby Database: A replica of the primary database which is constantly and
passively refreshing (ie. replicating) data from the primary
Primary Region: The region in which a user first provisions a primary database and enables
cross-region Autonomous Data Guard
Remote Region: The user-selected region in which to provision the standby from a database instance while enabling cross-region
Autonomous Data Guard.
Paired Regions: Two regions that are paired together to support X-ADG, such that a primary database may be provisioned in one of
the regions and its remote standby may be provisioned in the other region.
Recovery Point Objective (RPO): An organization's tolerance for data loss, after which business operations start to get severely
impacted
Recovery Time Object (RTO): An organization's tolerance for the unavailability (or downtime) of a service after which business
operations start to get severely impacted
London Frankfurt

Cross Region Data Guard

Cross Region Data Guard

If a regional failure occurs and your primary database is brought down, you may trigger a "Failover" from the remote standby
database to which you want to failover.
Failover across regions to the remote standby
• A failover is a role change - switching control from the primary database to the
standby database
• After a failover, a new remote standby for your new primary will be
automatically provisioned
….when the primary region becomes available again
• During a failover, the system automatically recovers as much data as possible
• Minimizing any potential data loss; there may be a few seconds or minutes of
data loss
• You would usually perform a failover in a true disaster scenario, - accepting
the few minutes of potential data loss to ensure getting your database back
online as soon as possible

Once your remote standby is provisioned, you will see a "Switchover" option on your database's console.
Switchover testing across regions with the remote standby
• Switchover from the remote standby database, while both your primary
and standby are healthy, performs a role change - of the primary
• Switching from the primary database to the remote standby database.
• May take several minutes, depending on the number of changes in the
primary database
• Switchover guarantees no data loss
• You would usually perform a Switchover to test your applications or
mid-tiers against this role change behaviour

4 - Export Data As
JSON To Object Storage

Export Data As JSON To Object Storage
ADB now has a procedure to export a query as JSON directly to Object
Storage bucket.
The query can be an advanced query - includes joins or subqueries.
Specify format parameter with compression option to compress the
output files.
Use DBMS_CLOUD.DELETE_OBJECT to delete the files
OVERVIEW
BEGIN
DBMS_CLOUD.EXPORT_DATA(
credential_name => 'DEF_CRED_NAME',
file_uri_list => ‘bucketname/filename’,
query => 'SELECT * FROM DEPT’,
format => JSON_OBJECT('type' value 'json'));
END; /
HOW IT WORKS

5: Wallet rotation and
using TLS instead of mTLS

Per-database with Instance Wallet selected:
• All existing database specific instance wallets will be void.
• Post rotation need to download new wallet to connect to database.
• NOTE - Regional wallets with all database certification keys continue to work
Regional level with Regional Wallet selected:
• Both regional and database specific instance wallets are voided.
• Post rotation need to download new regional or instance wallets to connect to any
database in region
• All user sessions are terminated for databases whose wallet is rotated.
• User session termination begins after wallet rotation completes, however this process
does not happen immediately.
New Option To Rotate Wallets For ADB

Most people do not like to configure wallets
• ADB used mTLS to establish the client-server
connection
• Both the client and the server have a special secret
key and its exchanged to be validated
• Going forward one can connect to ADB using TLS
instead of mTLS
• To make it secure
• To enable TLS on an ADB instance with a public
endpoint exposed
• One must have an Access Control List (ACL) in place
• Traffic outside of the VCN is blocked giving you
confidence that your connection is secured

END;

Automatic Partitioning
Automatic partitioning in ADB analyzes the application workload
Automatically applies partitioning to tables and their indexes to
improve performance or to allow better management of large tables
Automatic partitioning chooses from the following partition methods:
• INTERVAL AUTOMATIC: best suited for ranges of partition key values
• LIST AUTOMATIC: applies to distinct partition key values
• HASH: partitioning on the partition key's hash values
OVERVIEW
Automatic partitioning performs the following operations:
• Identify candidate tables for automatic partitioning by analyzing the
workload for selected candidate tables.
• By default, automatic partitioning uses the workload information
collected in an Autonomous Database for analysis
• Evaluate partition schemes based on workload analysis and
quantification and verification of the performance benefits:
1. Candidate empty partition schemes with synthesized
statistics are created internally and analyzed for
performance.
2. Candidate scheme with highest estimated IO reduction is
chosen as optimal partitioning strategy - internally
implemented to test and verify performance
3. If candidate partition scheme does not improve
performance automatic partitioning is not implemented
Implement optimal partitioning strategy, if configured to do so, for the
tables analyzed by the automatic partitioning procedures.

7: Set Patch Level When Creating
A Clone and retrieve Patch
Details

Set Patch Level When Creating A Clone
When you provision or clone an Autonomous
Database instance you can select a patch level to apply
upcoming patches.
There are two patch level options: Regular and Early.
The Early patch level allows testing upcoming patches one
week before they are applied as part of the regular patching
program
The console shows the patch level setting with the section
headed Maintenance.

16: Use Resource Principal
To Access OCI Resources

Use Resource Principal To Access OCI Resources
Copyright © 2021, Oracle and/or its affiliates
A resource principle authorizes an OCI resource to make API calls to certain OCI services (e.g.
Object Store)
This simplifies access to Object Stores
Autonomous Database can use resource principal credentials to access the specified Oracle
Cloud Infrastructure resources.
Typical use cases:
• Access data from an Object Storage bucket, perform some operation on the data, and then write the
modified data back to the Object Storage bucket.
• Access your vaults, keys, or secrets.
• List work requests or list work request errors.
OVERVIEW

Use Resource Principal To Access OCI Resources
1) Create a dynamic group
Tells IAM that a given Autonomous Database should be able to read from the Object
Storage buckets and objects that are in a given compartment
HOW IT WORKS
In the OCI console, go to ‘Identity and Security’ -> ‘Dynamic Groups’ -> ‘Create Dynamic Group’
To include only ADB-S instance to this dynamic group, add the instance OCID in the following rule:
resource.id = 'ocid1.autonomousdatabase.oc1.iad.osbgdthsnmakytsbnjpq7n37q'

HOW IT WORKS

Use Resource Principal To Access OCI Resources
2) Create a policy
Allow this resource to access our Object Storage bucket that resides in a given compartment
HOW IT WORKS
In the OCI console, go to ‘Identity and Security’ -> ‘Policies’-> ‘Create Policy’
Add your policy statement in plain text or use the Policy Builder.
Allow dynamic-group ctuzlaDynamicGroup to read buckets in compartment ctuzlaRPcomp
Allow dynamic-group ctuzlaDynamicGroup to read objects in compartment ctuzlaRPcomp
Note: It’s also possible to allow higher levels of access as described in the documentation

Use Resource Principal To Access OCI Resources
3) Enable resource principal in ADB-S
Resource principal is not enabled by default in ADB-S.
In order to be able to use resource principal in our ADB-S instance, we need to enable it using
the DBMS_CLOUD_ADMIN.ENABLE_RESOURCE_PRINCIPAL procedure:
HOW IT WORKS
As ADMIN user, execute the following statement:
EXEC DBMS_CLOUD_ADMIN.ENABLE_RESOURCE_PRINCIPAL();
PL/SQL procedure successfully completed.

19 - ADB now supports SQL
access to tenancy details

117 Confidential – © 2019 Oracle Internal/Restricted/Highly Restricted
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
