Oracle Database 11g Release 2Dynamic Cluster Partitioning via Server Pools

• Server Pools

– Dynamically assigns the server

resources required to run specific

workloads

• Both Application and Database

Pools

• Policy Managed

– Min and Max Servers

– Relative Importance

• Unassigned Servers go to Free

Oracle Database 11g Release 2Reduce I/O bandwidth requirement with Flash Cache

• A transparent extension of the database buffer cache

using solid-state disk (SSD) technology

– SSD acts as a Level 2 cache (SGA is Level 1)

– Faster than disk (100x faster for reads)

– Cheaper than memory ($50 per gigabyte)

– Large capacity (hundreds of gigabytes per flash disk)

• Fewer drives and better performance

– For I/O throughput, users often use hundreds of drives today

– Flash enables I/O throughput without all the drives

– Large jobs complete faster


Flash CacheHow it works

120 GB Flash Cache

16 GB SGA Memory

360 GBMagnetic Disks

Install Flash Drive in the Host Server

• Set two init.ora parameters:

• db_flash_cache_file = <filename>• Specifies the path to the flash disk

• db_flash_cache_size=<size>• Specifies the amount of flash disk to use

Extended Buffer Cache

Flash CacheThings to note

• Customers should test flash drives thoroughly – quality and

performance varies greatly today

• Large flash areas may require additional SGA for buffer

headers, approximately 2 – 4% of Flash Cache data

• With large flash drives, the time to “warmup” the cache and

deliver full benefit could be substantial

• Multiple flash drives may be combined via volume managers or

ASM

• Flash drives can use PCI, SCSI, or DIMM connections, as long

as they “look” to Oracle like a regular disk

• Optional storage clause FLASH_CACHE { KEEP | NONE } to

force a table or partition in or out of the cache

• Flash cache reduces read I/O, but does not affect write I/O


Oracle Database 11g Release 2ASM Supports All File Types

• ASM now supports all types

of files

– Database files

– Shared Clusterware files

(OCR/Vote Disk)

– File system files

Oracle Database 11g Release 2Automated Degree of Parallelism

• Currently tuning parallelism is a manual process

– one degree of parallelism does not fit all queries

– too much parallelism can flood system

• Automated Degree of Parallelism automatically

decides

• If a statement will execute in parallel or not (serial execution

would take longer than a set threshold – 30 secs)

• What degree of parallelism the statement will use

• Optimizer derives the DoP from the statement based

on resource requirements

– Uses the cost of all scan operations

– Balanced against a max limit of parallelism


Automated Degree of ParallelismHow it works

SQLstatement

Statement is hard parsed

And optimizer determines the execution plan

Statement executes serially

Statement executes in parallel

Optimizer determines ideal DOP

If estimated time greater than threshold

Actual DOP = MIN(default DOP, ideal DOP)If estimated time less

than thresholdPARALLEL_MIN_TIME_THRESHOLD


Oracle Database 11g Release 2Parallel Statement Queuing

• Automatic Degree of Parallelism means

– More statements will run in parallel

– Potential system thrashing due to too many processes

• Parallel Statement Queuing automatically decides if

a statement can execute immediately or not

• When a parallel statement starts it checks if enough

parallel servers (aka Parallel Query Slaves) are

available

– If not, queue the statement

– Once enough parallel servers become available, statement

is de-queued and executed


Parallel Statement QueuingHow it works

SQLstatements

Statement is parsed

and Oracle automatically determines DOP

If enough parallel servers available

execute immediately

If not enough parallel servers available queue

128163264

FIFO Queue

When the required number of parallel servers become available the first

stmt on the queue is dequeued and executed

Oracle Database 11g Release 2In-Memory Parallel Execution

• Data warehouse environments

can have large amounts of

memory that is not always

used

• An algorithm places fragments

of an object (partitions) in

memory on different nodes

• Compression gets more data in

memory

• Parallel servers (aka PQ

Slaves) are then executed on

the corresponding nodes

• Requires Automatic Degree of

Parallelism

Real Application

Clusters


In-Memory Parallel ExecutionHow it works

SQLstatement

Determine the size of the table being looked at

Read into the buffer cache on any node

Table is extremely small

Always use direct read from disk

Table is a good candidate for In-Memory Parallel

Execution

Table is extremely Large

Fragments of Table are read into each node’s

buffer cache

Only parallel server on the same RAC node

will access each fragment

Real-Time

Query

• Read-only queries on physical standby concurrent with redo apply

– Supports RAC on primary / standby

– Queries see transactionally consistent results

• Handles all data types, very fast, operationally simple

– But not as flexible as logical standby

• Immediate appeal to the many users of physical standby

• DR with real time query is unique in the industry – no idle resources

Now supports

Incremental backups!


Snapshot Standby – Leverage Standby

Database for Testing

• Convert Physical Standby to Snapshot Standby and open for writes by testing applications

– ALTER DATABASE CONVERT TO

SNAPSHOT STANDBY;

• Discard testing writes and catch-up to primary by applying logs

– ALTER DATABASE CONVERT TO

PHYSICAL STANDBY;

• Preserves zero data loss

– But no real time query or fast failover

• Similar to storage snapshots, but:

– Provides DR at the same time

– Single copy of storage

• No idle resources

Oracle Database 11g Release 2Online Application Upgrade

• Large, mission critical applications are often

unavailable for tens of hours while a patch or an

upgrade is installed

• Oracle Database 11g Release 2 introduces

revolutionary new capabilities that allow online

application upgrade with uninterrupted availability of

the application

• The pre-upgrade application and the post-upgrade

application can be used concurrently


Online Application UpgradeRequirements

• The installation of the upgrade into the production

database must not perturb live users of the

pre-upgrade application

– Many objects must be changed in concert. The changes

must be made in privacy

• Transactions done by the users of the pre-upgrade

application must by reflected in the post-upgrade

application

• For hot rollover, we also need the reverse of this:

– Transactions done by the users of the post-upgrade

application must by reflected in the pre-upgrade application


The solutionEdition-based redefinition

• Revolutionary new features:

– edition

– editioning view

– crossedition trigger

• Code changes are installed in the privacy of a new edition

• Data changes are made safely by writing only to new

columns or new tables not seen by the old edition

– An editioning view exposes a different projection of a table into each

edition to allow each to see just its own columns

– A crossedition trigger propagates data changes made by the old

edition into the new edition’s columns, or (in hot-rollover) vice-versa


Oracle Database 11g Release 2 Database Security

• Encryption and Key Management

– Change / re-key TDE tablespace encryption master keys
