BETA TESTING

• Beta 3 Testing : January 14-18, 2013

• IOUG, ODTUG, UKOUG, AUSOUG

• Upgrades, Downgrades, and other features

• How to get involved

WHY ARE WE HERE TODAY?

BLOG POSTS…

• Multi-Tenancy• CDB vs. PDB• Split Data Dictionary• Compatible: RAC, Resource Manager etc• New Administrator: CDB Administrator

• SQL> SELECT pdb FROM dba_services;• SQL> SELECT

sys_context(‘userenv’,’con_name’) “MY_CONTAINER” FROM dual;

• SQL> SELECT NAME, CON_ID FROM v$active_services ORDER BY 1;

• Unique Service Names for PDBs• Database Administration & Granularity Control• Pluggable Databases Examples: Create PDB

• $ sqlplus sys/pwd@DBSRV/c01p as sysdba• SQL> create pluggable database c01p01p•   2  admin user app_Admin identified by pwd•   3  file_name_convert = ('/pdbseed/',

'/c01p01p/')•   4  /

• Pluggable Databases Examples: Drop PDB• Pluggable Databases Examples: Clone a PDB

NEW FEATURES HIGHLIGHTS

MATURE TOOLS

DBUA: ENHANCEMENTS• Upgrade from 10.2, 11.1 and 11.2• Move database across 12.1 Oracle Homes

DBUA: PRE-UPGRADE SCRIPTS

• $ORACLE_HOME/rdbms/admin/preupgrade.sql – executed using existing 11g Home• Results in: $ORACLE_HOME/cfgtoollogs/$ORACLE_SID/preupgrade

DBUA: PRE-UPGRADE CHECKS

DBUA – UPGRADE OPTIONS• Parallel Upgrade – Runs catctl.pl with selected parallelism• Gather Dictionary Statistics before upgrade• Set User Tablespaces Read Only• Update diagnostic and audit file destinations

DBUA – PARALLEL UPGRADENEW Parallel Upgrade

DBCA – NEW FEATURES• New User Interface• Support for Pluggable Databases• One Step Database Creation• EM Database Express Configuration• Simplified OLS and Database Vault Configuration• CVU Integration• Listener Creation (Single Instance)• Password File on ASM Diskgroup• Flex ASM Support• Grid Management Database Creation (GI Home)

DBCA – UI ENHANCEMENTS• Streamlined RAC and Single Instance flows• Simplified flows with reduced number of steps• Look and feel consistent with Oracle Install and Configuration wizards

• Create CDB with zero or more PDBs• Uses catcon.pl to run DB creation scripts for CDB. Catcon.pl creates the

dictionary objects in ROOT and PDB$SEED• All Oracle supplied schemas are always installed in CDB• Option to generate CDB creation scripts

DBCA – CONTAINER DATABASES

DBCA – MANAGEMENT OPTIONS• DB Express replaces DB Control• By default DBCA picks up free port for EM Database Express from 5500 to

5599 range• Override using “DBEXPRESS_HTTPS_PORT” environment variable

before running DBCA/Installer• DBSNMP is used by CVU for periodic database checks• Register Database, ASM and Listener targets to EM Cloud Control

DBCA – CREATE PLUGGABLE DATABASES• Create a new PDB (using PDB$SEED)• Plug using PDB Archive (tar.gz) generated using DBCA Unplug operation• Plug using PDB File Set (PDB XML + RMAN Backup) generated using DBCA

Unplug operation

DBCA – UNPLUG A PLUGGABLE DATABASE• PDB Archive is one tar.gz file consisting all unplugged datafiles and PDB

metadata XML• PDB File Set consists of two files

• RMAN backup of all PDB data files• PDB metadata XML

• PDB File Set is the only supported option when unplugging PDB on ASM

• New with this release of Oracle Database• A few acronyms to account for:

• Non-CDB = Traditional Database• CDB = Container Database• PDB = Pluggable Database

• New SQL • pluggable database• alter session set container

• New Views• CDB Views (933) – CON_ID• PDB Views (2) – PDB_ID (CDB_PDBS)

PLUGGABLE DATABASES

• Faster provisioning – New or Copy• Developers?

• Fast Redeployment – moving platforms

• Patch/Upgrade Faster • Multiples for the cost of doing it once• Patch/Upgrade to later version by

unplug/plug

• Run Multiple Database Instance• Up to 252 instances – single box

PLUGGABLE DATABASES - BENEFITS

Steps:1. Upgrade to 12.1 and drop TEMP2. SQL>exec DBMS_PDB.DESCRIBE (<xml

file>);3. SQL>create pluggable database PDB12

using <xml file> nocopy;4. Connect: Sqlplus “sys/<pwd>@PDB12 as sysdba”

Note:Will need to change service name/connection string

TRADITIONAL TO PLUGGABLE

• New RMAN command• Pluggable Database

• Backup entire CDB and single/multiple PDB• Consistent Point-in-Time• Tablespaces/Data Files from specific PDB

• Beta 3 – PIT now available for PDB

• Bug: 16187090• NoArchivelog/Full Online Backup

RMAN> backup database;• Workaround = Don’t do it

PLUGGABLE DATABASES - RMAN

• New Clusterware based topology• Hub Nodes = Traditional (database)• Leaf Nodes = Lighter weight stack (applications)

• Enables a variety of workload and applications across hundreds of nodes• No additional overhead

• What-If Evaluation• New command to help determine impact to

cluster

• OCR backup to ASM supported

RAC: FLEX CLUSTER

• ASM is decoupled from database servers

• Shared Password File in disk group

• ASM Resync• Allow multiple disks to be

brought online simultaneously

• Control speed of resync

RAC: FLEX ASM

• Far Sync:• NoAffirm Redo Transport• Receipt is acknowledged as soon as redo is received in memory• Standby does not wait for write to standby redo log• Increases primary database performance• Increases maximum availability and SYNC redo transport

• Single Command Role Transitions:• Replacement for multiple commands• Higher availability with simpler and faster role transitions
