Memory-optimized RDBMS for real-time applications

“When milliseconds matter”

When You Think “Database…”

RDBMS + client/server connectivity• Data accessed by client application via the network• Not fast enough for some applications

Why Is TimesTen So Fast?

• In-Memory Database• Entire database is always in memory• Designed and optimized for memory layout • No buffer cache management overhead• Shorter code path = faster performance• Fewer CPU instructions = fewer processors required

• Direct-link to the database• Application can link TimesTen directly into its address space • Eliminate network and inter-process communication overhead • Very low response time (like calling a procedure)

Cache Connect to Oracle

• Improves application response time

• Cache tables from Oracle database• Cache individual tables and related

tables

• Cache all or subset of rows & cols

• Automatic data synchronization• TimesTen to Oracle• Oracle to TimesTen

• Access cache tables like regular database tables using SQL• Joins/search, insert/update/delete

Types of TimesTen Caches

• Read-only Cache• Updates in Oracle Database propagated automatically to TimesTen

• Updatable Cache• Asynchronous write-through transactions batch-committed in Oracle

Database• Synchronous write-through transactions available optionally

• Static Cache• Entire content of cache is pre-loaded prior to doing any work

• Dynamic Cache• Data loaded transparently from Oracle Database if not found in

TimesTen• Automatic data aging from TimesTen: LRU and timestamp based

Benefits of Caching in TimesTen

• Reduced application response time• Read and Write transactions are completed more quickly in

TimesTen

• Very high throughput• Multiple caches provide horizontal scaling

• Reduced workload on the Oracle Database• More computing resources are available for other workloads on

the database tier

• Run on commodity hardware• TimesTen is available on 20 popular platforms

Cross-Tier High AvailabilityIntegration with Oracle Database RAC

• Automatic recovery from Oracle Database RAC node failures using TAF and FAN• Automatic reconnection to the

cluster

• Automatic resumption of updates from Oracle to TimesTen

• Automatic rollback of in-transit update transactions from TimesTen to Oracle and their resubmission

• No loss of transactions

3. Highly Scalable

1. Instantly Responsive

2. Tightly Integrated

Which Embeddable Database?

• Choose Oracle Database when:• Advanced features (spatial, triggers, stored procedures) are required• Clustering via RAC or integration with Fusion Middleware is required• Footprint is not a constraint

• Choose TimesTen when:• Low latency and high throughput required• Oracle caching is needed• SQL is required• Database fits into memory

• Choose Berkeley DB when:• Low latency and high throughput required• Data access is predictable• XML/XQuery is required

• Choose Oracle Lite when:• Devices may be occasionally disconnected from the network• Synchronization to Oracle Database is required• Small footprint is required• SQL is required
