*Lead author and co-author on couple of books,
latest, “Expert Enterprise Manager 12c” from Apress
*Current hobby is WIT, (Women in Technology) and
O.W.L., (Oracle Without Limits) for RMOUG 2014

*
*Released June 25th, 2013 to the general public
*Loads of new features, “Pluggable Database” is
the most anticipated and talked about.
*Beta program was very successful, ran for over
1 year to test through partners and user groups
the features and capabilities of product.
*Multi-Tenancy is the new THANG…don’t forget!
*Everything is going the way of the cloud- SaaS,
DBaaS, PaaS…then DBAs

*
*Concept is familiar to MySQL and MSSQL DBA’s
as attach/detach with standard system/user
database.
*Allows sharing of SGA, background processing
and most of data dictionary into “Container
Database”, (CDB)
*aka “multi-tenancy” offers high sharing, secure
containment of databases and lower costs.
*Allows easy migration of user/pluggable
databases, (PDB) between platforms, releases
and systems.

*
*Shared SGA and PGA
*Single set of
Background Processes
*All in Container
Database
*Pluggable databases,
“plugged in” to
container database
*EM Express Default
Installation for Added
Support

*
*Ability for resources to be shared and yet
security and environment to be separate for
auditing and processing purposes.
*Exceptionally valuable when consolidating and
offering maximum return on investment.
*Simplifies administration.

*
*Oracle System dictionary resides in the
Container Database.
*The SGA and PGA global allocation
*RAC and Dataguard compatible
*CDB “Root Namespace”
*High Consolidation Density by sourcing so much
in the CDB!
*Where first virtualization and many Oracle
Homes created more complexity and upkeep in
previous versions of Oracle.

*
*High Consolidation Density
*Rapid Patches and Upgrading
*Manage Many Database as One
*Advanced and Dynamic Resource Management
of Shared Resources
*Rapid Provisioning and Cloning

*
*“Sealed” off from any other PDB and self-
contained.
*Read-only copy of CDB data dictionary
*Will use service names over Oracle SID for
connections.
*Pre-12.1 databases can be migrated into PDB
*Rman, Dataguard can be at PDB level or CDB
level! PDB has granular control over both.

*
*Simple unplug method
*Database is simple XML output file.
*Plugging in is simple commands/file direction
*Simple cloning from one pluggable to another.
*Each Pluggable is “self-contained”
*Take extra care when utilizing OMF, (Oracle
Managed Files) Clone Failures can occur with
standard “clone and creation” scripts.

*
*Migrate to new platform
*Migrate to new hardware
*Migrate and upgrade to new database release
*Move database with ease to new system with
more resources.
*Added enhancement for high availability, as
moving is straight forward.

*
*CON_ID=0 is for instance level.
*CON_ID=1 is for the Container database
*CON_ID=2 is for the seed database
*CON_ID>1 is for pluggables

*
*One word: CON_ID
Select name, con_id from
v$active_services
where con_id !=1;
*Utilize many of your same queries, but add into
where clause, “CON_ID=<con_id for PDB>;” using
the v$/GV$ views

*
*ALTER SESSION SET CONTAINER = pgtst12c2;
*Show statements:
*And once you have “altered” your session-

*
Same V$ query you’d use to look at datafiles in
previous versions, just added the con_id to the
where clause!

*
*These replace the DBA Views when you move from
single instance to Pluggable database.
*Easily replaced, comfortable scripting, just replace
your DBA with CDB:
*Yes, there are over 900 new CDB views… 
*Two PDB views at Container level

*
*All data is shown with subcategory of what PDB
derived from in main AWR report.

*
*This includes Datafiles and Objects

*
*“Top Container”
*Very little data broken down by PDB at this
time:

*
*Marketed as replacement for DB Console
*Available to PDB’s post configuration of the DBMS
package (DBMS_XDB_CONFIG.SETHTTPPORT).
*High performance tools available with no overhead
to database.
*Great tool to grant to developers if you aren’t
willing to grant access to EM12c.
*Has own entry in listener.ora, (yes listener must be
running to connect)
*Uses FlashPlayer currently, but will be rewritten
soon!

*
*Virtualbox has a lot of support from Oracle
*VMWare is the most trusted.
*Images easy to locate.
*Shortcuts can save you a lot of time.

*
*Call for Abstracts are Open!
*Best Grass-roots Conference in the US!!
*February in Denver, CO.
