    Application Application Application Telco Services Financial Services CRM, Portal, SaaS, Customer-facing Applications Real-Time BAM & BI Memory-optimized RDBMS for real-time applications “ When milliseconds matter”
  • 7. When You Think “Database…”
    • RDBMS + client/server connectivity
    • Data accessed by client application via the network
    • Not fast enough for some applications
    SQL Results Application RDBMS Application
  • 8. RDBMS with Home-Grown Cache
    • For very demanding applications:
    • Build a home grown, application-specific, in-memory “cache”

  • 12. 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)
  • 13. Oracle TimesTen Delivers Lightning Fast Response
  • 14. Oracle TimesTen Offers Outstanding Platform Efficiency
  • 15. Replication – TimesTen to TimesTen
    • Real-time transactional replication
      • Between TimesTen databases
    • Flexible configuration
      • Active-standby, Active-active, N-way
    • High performance
      • Asynchronous replication
      • Synchronous replication
    • Robust and reliable
      • Auto recovery, master catch-up
      • Conflict detection and resolution
    • Support online upgrade
      • No downtime, cross version replication

  • 17. 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
    Cache Agent Checkpoints Tx Logs Network Client- Server Cache Tables Direct-linked Application TimesTen Libraries TimesTen Client lib Application
  • 18. 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
  • 19. 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
  • 20. Cross-Tier High Availability Integration 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
  • 21. Oracle TimesTen + Oracle Database End-to-End Data Management 3. Highly Scalable 1. Instantly Responsive 2. Tightly Integrated
  • 22. 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
