Benefits of Multitenant

Manage Many Databases As One– Patch and upgrade one multitenant

container databaseIncrease server utilization– High density database consolidation

per server Backup many database as one – Backup one multitenant container

databaseProvision Databases Rapidly– Single step to clone database instantly

Move Database rapidly– Easy to move database (UnPlug&Plug)

Dynamic resource management between pluggable databases.

Oracle Data Guard 12c

FAST SYNC

SYNC NOAFFIRM with Maximum Availability Mode– Fast Sync provides an easy way of improving performance in

synchronous zero data loss configurations also allows a standby to acknowledge the primary database as soon as it receives redo in memory, without waiting for disk I/O to a standby redo log file.

FAR SYNC

Far Sync instance is like a little cascading destination standby database. Far Sync instance is not have any data filesA Far Sync instance manages a control file, receives redo into standby redo logs (SRLs)

Oracle Real Application Clustersand Grid Infrastructure

Flex Cluster

12c Cluster – Traditional and Flex Cluster

Hub nodes and Leaf nodes – Multiple Leaf nodes can use single Hub node– Hub nodes have direct access to OCR/Voting disks

– Flex ASM required for Flex Cluster

04/10/2315

$ ./crsctl get cluster mode status$ ./crsctl get cluster mode status

Flex ASM

Oracle Clusterware automatically starts surviving ASM Instance on different node, when ASM Instance Failed on a Node Load balancing capabilities for the instances running on the nodes

Additional new features

Tuning ASM rebalance operations– EXPLAIN WORK FOR operation and V$ASM_ESTIMATE view

ASM Disk Scrubbing

V$ACTIVE_SESSION_HISTORY view for ASM instanceIncreased ASM Storage limits – Support 511 ASM Disk group, ASM disk can be 32PB

OCR can be backed-up in ASM Disk group
