*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.
