• Hardware Replacement (disk,
memory etc)
• Customer liasing via CSM
McMaster
Operations
• Co-ordination of onsite part
replacement.
• Provide physical access to Oracle

• Access to additional
storage (NFS)
Enterprise Networks • F/W rules – On Going

MIGRATION TO EXACC
Journey from Commodity Hardware to EXACC

AT MAC – MIGRATION TO
EXACC
Migration Tools
Cloud UI
DBCA
Migrations Strategies
Import/Export
Transportable Tablespaces
Restore and Clone

EXACC
Cloud UI
•Used to create service instances.
•Allows DBA’s to perform EXACC Specific Management
and Monitoring
•Burst for capacity on demand.
•Start and stop databases and compute nodes.
•Some limited monitoring capabilities

EXACC
Cloud UI (Continued)
•Used to create EXACC Databases
•Recommend way to create all databases on
EXACC.
•For 12CR1 and above, CDB’s and a starter
PDB are created.
•All databases RACed (all versions)
•Used to create MAA databases.
•Can be used to apply databases patches.

EXACC
DBCA
•More traditional tool used for database
creation.
•For the purposes of PeopleSoft
migrations at make, used to create a
standalone staging database.
•On EXACC must be run from an
existing Oracle Home created via the
Cloud UI.

EXACC
Factors Influencing the Migration
Strategy
McMaster is not a 24 X 7 shop.
Production PeopleSoft Streams at McMaster have negotiated
monthly weekends.
NonPeopleSoft environment outages negotiated with
stakeholders around business cycles.
Relative size of database also contributes to the choice of
migration strategy.

MAC – MIGRATION TO EXACC
Creating a Database on EXACC
VIA Cloud UI
All strategies required the creation of database via
Cloud UI.
Access to Cloud UI is via a web interface hosted
by the OCC.
EXACC rack location, version and availability
requirements need to be known prior to
creation of database.

MAC – MIGRATION TO EXACC

EXACC IMPLEMENTATION AT MAC
– MIGRATION TO EXACC
MIGRATION
METHODS
Import/Export
•Useful when migrating small
databases.
•Use Data pump to export
application schemas from
source database.
•Use database pump to import
database into pdb.
Tranportable Tablespaces
•McMaster Use Case: PDB
unplug/plug migration failed
on EXACC due to DataPatch
Roll back issue.
•Place source application
tablespaces in read only mode.
•Copy application datafiles to
staging location.
•Perform Metadata export of
source database.
•Copy datafiles from staging
location into ASM on EXACC
target.
•Import metadata into target
PDB
Restore/Clone
•Create non CDB staging
database off existing EXACC
home using DBCA.
•Perform RMAN backup of
source database.
•Restore RMAN backup to
staging database.
•Clone database as PDB to
target CDB.
•Perform PDB conversion
activities.
•Patch PDB

EXACC
As a result of implementing
EXACC McMaster has seen
two types of benefits:
Direct Benefits
Indirect Benefits

TRANSFORMATIV
E IMPACT OF
EXACC
Direct Benefits
• Greatly Reduced Complexity of, and effort required
to manage, McMasters’s Oracle Environment.
• Performance Improvements:
• PSQuery and Data Warehousing components saw
immediate performance impacts with little tuning
required.
• Database cloning/refresh times greatly reduced.
• Partitioning allows for performance gains.

TRANSFORMATIVE IMPACT OF
EXACC
Indirect
•Allowed us to review database we support and
remove those that were no longer needed
•Catalyst for review and modification of our
PeopleSoft Instance strategy and environment
geometry
•Allowed for us to pursue end to end refreshes
of our PeopleSoft environments.
