TimesTen In-Memory Database


The Quest for Response Time

• Failure to meet service level agreements (SLA)– Due to long response time

• Customer churns– Competitive products offer better response time

• Decreased user productivity and decreased customer satisfaction– Unhappy customers

• Loss of revenue and decreased profitability– Effect of lost business and opportunities

Why is Response Time Important?


Improving Application Response Time

• Define business requirements for latency

• Evaluate solutions

What is Oracle TimesTen In-Memory Database

• Extremely fast – Entire database in memory– Microsecond response time

• Compatible with Oracle Database– Standard SQL and PL/SQL, Datatypes

– JDBC, ODBC, ODP.NET, OCI, Pro*C

• Persistent and Recoverable– Transactional logging and checkpointing

• Easy to use and deploy

Why is TimesTen In-Memory Database so fast?

• In-Memory Optimizations– Database in shared memory– Memory optimized access methods– Faster than fully-cached disk-based

databases

• Direct-link for best performance– Shared memory mapped into

application process– Eliminates networking overhead

IMDB Cache GridIMDB Cache Grid

• Application-tier In-memory RDBMS

• Accelerates applications• Uses standard SQL and PL/SQL• Caches Oracle Database tables

• Read-write caching• Dynamic and static• Automatic synchronization

• Scales up and scales out• Built-in high availability


In-Memory Database CacheFlexible Cache Group Configurations

Application Transactions Cache Groups

Automatic Data Synchronization

• Cache Group describes the data in the Oracle database to cache

• Collection of related tables– All or subset of rows and columns– Defined via SQL clause

CREATE CACHE GROUP nameFROM owner.tab1 (col1, col2), owner.tab2 (col1, col4)…WHERE <predicate>

• Cache tables are regular database tables in TimesTen

– Joins/search, insert/update/delete


In-Memory Database Caching

Read-Write caching• Transactions committed in TimesTen

cache• Parallel write-through of committed

transactions to Oracle Database

Read-only caching• Transactions committed in Oracle

Database• Multi-stream refresh of committed

Incremental Scalability


Flexible Caching Options

• Read-Write and Read-only• Pre-loading of cache

– Data set pre-determined

• On-demand loading of cache– Data set not pre-determined or too large

• Performance driven – Locality optimized for consistent response time– Globally shared across all nodes for application transparency– Scale-out horizontally with processing capacity


What does TimesTen offer for high availability?

TimesTen Replication provides real-time replication of transaction data between TimesTen databases


Real-Time Transactional Replication

• High performance – Synchronous / Asynchronous

– Memory-to-memory replication

– Parallel send of log streams

– Parallel apply of changes on Standby and Subscribers

• HA and DR support• Online upgrades – no downtime

Minimal Application Changes

• PL/SQL support– PL/SQL engine implemented inside TimesTen database– Same Oracle PL/SQL language; subset of packages

• C/C++ support– Standard ODBC interface

• Java support– Standard JDBC interface

• Oracle APIs: ODP.NET, OCI, Pro*C/C++– Support identical API signatures as used for the Oracle Database; subset of functions

• Minimal application changes
