How Does EM12c Help?
Oracle Confidential – Internal/Restricted/Highly Restricted 13
• Create a Database in Minutes with Dramatically Reduced Storage
• Automate & Track Your Patch Process
• Find Out Regressed SQL from Millions of Statements to Ensure Database Performance
• Keep with Standard and Security Best Practices
![Page 14: Apouc 2014-enterprise-manager-12c](https://reader035.vdocuments.mx/reader035/viewer/2022062703/554fccfbb4c90542018b537c/html5/thumbnails/14.jpg)

Scenarios & Problems to Solve
• 12 TB database in production for an internal application
• The production DB is running on Exadata, while a standby database is running on ZFSSA
• Agile development is used for the internal app with 7 sprints running in parallel
• Each sprint requires a clone of the production DB
• Each sprint lasts for a month, and clones need to be refreshed monthly as well
Case 1: Telecom Industry
Storage requirements
using traditional cloning
Prod DB = 12 TB
Standby DB = 12 TB
7 Clones (7 * 12 TB)
= 84 TB
------------------
Total 108 TB
Time = days/weeks
![Page 15: Apouc 2014-enterprise-manager-12c](https://reader035.vdocuments.mx/reader035/viewer/2022062703/554fccfbb4c90542018b537c/html5/thumbnails/15.jpg)
Copyright © 2014 Oracle and/or its affiliates. All rights reserved. |
Scenarios & Problems to Solve
• 5 production databases total 30 TB of storage
• All 5 production DBs have a standby
• Clones of the production database are required for data analysis and reporting
• 6 total clones across different teams every quarter
• For security reasons, sensitive data has to be masked prior to cloning
Case 1: Banking Industry
Storage requirements
using traditional cloning
5 Prod DB = 30 TB
5 Standby DB = 30 TB
5 Masked DB = 30 TB
6 Clones (6 * 30 TB)
= 180 TB
------------------
Total 270 TB
Time = days/weeks
![Page 16: Apouc 2014-enterprise-manager-12c](https://reader035.vdocuments.mx/reader035/viewer/2022062703/554fccfbb4c90542018b537c/html5/thumbnails/16.jpg)

Database-Aware Snap Clone
• Leverage storage level snap clone feature
• Out-of-box self service portal
• Resource quota based on role
• Integrated monitoring, snapshot/rollback, etc
![Page 17: Apouc 2014-enterprise-manager-12c](https://reader035.vdocuments.mx/reader035/viewer/2022062703/554fccfbb4c90542018b537c/html5/thumbnails/17.jpg)

Continuous Replication using:
Golden Gate or Dataguard
Standby Database [on ZFS Storage Appliance]
Production Database [Exadata or any commodity hardware]
Snap Clones using Standby
Private backups (snapshots) for SSA user
Scenario 1: SnapClone Using Standby
DR Database [Exadata or any commodity hardware]
![Page 18: Apouc 2014-enterprise-manager-12c](https://reader035.vdocuments.mx/reader035/viewer/2022062703/554fccfbb4c90542018b537c/html5/thumbnails/18.jpg)
Copyright © 2014 Oracle and/or its affiliates. All rights reserved. |
Discrete Replication using: RMAN
backups, Netapp SnapMirror, etc
Test Master Production Database [Exadata or any commodity hardware]
Masking and Subsetting using EM
Snap Clones using Test Master
Private backups (snapshots) for SSA user
Benefit: Massage data before cloning
Scenario 2: SnapClone Using Test Master
DR Database [Exadata or any commodity hardware]
![Page 19: Apouc 2014-enterprise-manager-12c](https://reader035.vdocuments.mx/reader035/viewer/2022062703/554fccfbb4c90542018b537c/html5/thumbnails/19.jpg)

Customer Scenarios with Snap Clone
Customer Scenario 1 [Telecom Industry]
Prod DB = 12 TB
Standby DB = 12 TB
7 Clones (7 * 2 GB of writable space)
= 84TB 14 GB
-------------------
Total 108 ~24 TB
Time = days/weeks minutes
Customer Scenario 2 [Banking Industry]
5 Prod DB = 30 TB
5 Standby DB = 30 TB
5 Masked DB = 30 TB
6 Clones (6 * 5 * 2 GB of writable space) = 180TB 60 GB
---------------------
Total 270 ~90 TB
Time = days/weeks minutes

PATCH MANAGEMENT $70 Billion revenue in 2011
75,000 employees
96 million retail customers
FOCUS ON Automation
Challenge:
• Patch and upgrade large number of databases with minimal maintenance time
• Regulations require quarterly patching for compliance management & reporting
• Mandatory to apply PSU to over 520 databases 2 time a year
• Inventory tracking and deploying changes to non-production databases was difficult
• During patching periods, DBAs worked extra hours on nights & weekends
After Oracle Enterprise Manager:
• Patching process is now automated
• 4 times reduction in man hours for patching resulting in approx 67% savings in productivity
• Application team can track changes across non-production and production environments resulting in no impact to development work providing more time for coding & testing
• DBA team now focused on database availability, scalability & performance
• IT runs like a business and adds value
