Oracle Multitenant and Oracle RAC
Winning combination of scalability & reliability for consolidated databases
Oracle Multitenant
& Oracle RAC
•  Scalability
•  Flexibility
•  Reduced Costs
Oracle RAC: Scalable, Reliable
Oracle Multitenant
•  Consolidation means
“putting all your eggs
in one basket”
•  Consolidating many
databases into one
demands scalable
platform
Oracle RAC
•  Means managing
many nodes in the
cluster as one system
•  Provides resiliency
against individual
server failures
•  Allows for horizontal
scaling
Multitenant: Simplify Consolidation

Oracle Multitenant Architecture – Dynamics
!  PDBs share common SGA
and background processes
!  Foreground sessions see only
the PDB they connect to
Copyright © 2013, Oracle and/or its affiliates. All rights reserved.10
Advantages of Oracle Multitenant Architecture
Reduced CapEx & OpEx, Increased Agility, Easy Adoption
Self-contained PDB for each application
!  Applications run unchanged
!  Rapid provisioning (via clones)
!  Portability (via pluggability)
Shared memory and background processes
!  More applications per server
Common operations performed at CDB level
!  Manage many as one (upgrade, HA, backup)
!  Granular control when appropriate

Why Use Services?
In a Single Instance environment the default service may be enough
!  The default service of the CDB is started when
the CDB is started. This is an admin-service.
!  The default service of the PDB is available
for connectivity as soon as PDB is mounted
with the startup of the CDB.
!  If an application uses the default service for
connectivity, it can connect to this service as
soon as it is registered with the listener.
–  How to prevent an application from connecting?

HRg1wc
Why Use Services?
Using the default service is not enough when moving PBS around
!  PDBs provide location independency (plug /
unplug / clone), but exist within an environment
!  Moving PDBs between environments
may require changing names of PDBs.
!  Use services to provide a “dial in number” for
your application. If the PDB moves to another
location, you can keep the number.
–  This requires uniqueness of service names

Use Services with Policy Managed Databases
For better HA and workload management
!  Oracle RAC-based systems allow for
management of services based on policies.
!  Server Pools are used to group workload to run
on either one or a group of servers in the pool.
!  Using policies allows for adapting to changes
in demand (Dynamic Database Services)

In a Single Instance environment the default service may be enough !  The default service of the CDB is started when the CDB is started. This is an admin-service. !  The default service of the PDB is available for connectivity as soon as PDB is mounted with the startup of the CDB. !  If an application uses the default service for connectivity, it can connect to this service as soon as it is registered with the listener. –  How to prevent an application from connecting? rudolph cdb1 sqlplus <user>/<pwd>@MySCAN/crmsvc CRM PDB Default service HR PDB CRMSVC Copyright © 2013, Oracle and/or its affiliates. All rights reserved.16 HRg1wc Why Use Services? Using the default service is not enough when moving PBS around !  PDBs provide location independency (plug / unplug / clone), but exist within an environment !  Moving PDBs between environments may require changing names of PDBs. !  Use services to provide a “dial in number” for your application. If the PDB moves to another location, you can keep the number. –  This requires uniqueness of service names rudolph cdb1 CRM PDB HR PDB CRMSVC cupid cdb1 NewHR PDB
