Use Case 1
Copyright © 2021 Oracle and/or its affiliates.
ABCCorp has its Multitenant Production databases on Exadata and wants quick clones its
Pluggable Databases for testing within the Exadata
What would you do ?
• Your DBA creates a Test Master from the PDB of interest. This Test Master resides on ASM
Diskgroup on the Non-Production appliance
• Exadata Snapshot clones on Sparse ASM Diskgroup are created
• Test Master and Clones are periodically refreshed from the production database

Read Only Snapshot Databases
Sparse files contain only changed blocks
Fast space-efficient Snapshot database
creation
 Create sparse diskgroup on Exadata
storage
 Then create snapshot database or
snapshot PDB that reads from base
read-only copy of DB and writes to
sparse diskgroup
Available for Self-Service consumption
Integration with pluggable database enables
creation of DB snapshot with Single Click
All Exadata features work on Snapshots
(smart scans, smart flash cache, resource
management …)
Non-Production
ASM
Non-Production
TopCorp has all Production databases on Exadata Environment and all the Standby databases outside
Exadata on ZFS Storage. They require Snapshot clones for Dev/Test outside the Exadata appliance.
What would you do ?
• DBA decides to follow the self-service model for provisioning clones to have more control on
Snapshot creation, management and rapid deployment
• DBA, as a Cloud Administrator flags Standby Database as Test Master
• Schedules Data Profile Creation after anonymizing the data at the Test Master and thereafter does
Data Profile refresh periodically
• Opens up clone creation for SSA Users by creating a Service Template that uses the above created
Data Profile as source
• SSA User creates cloned database with a simple interface and thereafter refreshes the cloned
database to latest copy of the Data Profile

  • 16. TopCorp has all Production databases on Exadata Environment and all the Standby databases outside Exadata on ZFS Storage. They require Snapshot clones for Dev/Test outside the Exadata appliance. What would you do ? • DBA decides to follow the self-service model for provisioning clones to have more control on Snapshot creation, management and rapid deployment • DBA, as a Cloud Administrator flags Standby Database as Test Master • Schedules Data Profile Creation after anonymizing the data at the Test Master and thereafter does Data Profile refresh periodically • Opens up clone creation for SSA Users by creating a Service Template that uses the above created Data Profile as source • SSA User creates cloned database with a simple interface and thereafter refreshes the cloned database to latest copy of the Data Profile Use Case 2 Copyright © 2021 Oracle and/or its affiliates.
