14 Analytics Use Cases for Oracle TimesTen

15 In-Memory Analytics - Summary Aggregates Scenarios Aggregations are suitable for analysis of higher-level grains of FACT data Knowledge of query patterns required Aggregated tables and indexes typically much smaller than detail-tables Reports using summary aggregates typically provide exceptional response time (sub-second) Operational Data Store 1 2 Reports Using Aggregate Set 1 OLTP Data Warehouse Summary Aggregate Tables and Indexes stored in TimesTen Reports Using Aggregate Set 2

16 In-Memory Analytics - Data Mart Use Cases Subset of Data from a Data Warehouse Data mart and operational data stores For analysis where summary aggregates are not sufficient Require access to detail source tables (fact and dimension tables) Consider hot set of data* Data volume constrained by availability of RAM in the system May use compression to include more data Common use cases have both aggregations and detail tables If the entire data warehouse is too big to fit into memory, only load portion of the data to TimesTen

17 In-Memory Analytics ODS and Data Mart Detail Tables Scenarios Operational Reports Operational Data Store OLTP Data Warehouse Aggregates + Detail tables + indexes Reports with Aggregates AND Detail Tables

18 Best Practices Tips and Tricks

19 TimesTen In-Memory Database Storage Speed Matters to Database Restart Time Storage speed matters Faster read operations using Flash and Solid State Disks Higher throughput with parallel threads Significant time reduction for database load to memory TimesTen Checkpoint Files 19

22 TimesTen Cost-Based SQL Optimizer Proper Indexes and Up-to-date Statistics Optimized Query Execution Plans Hash indexes Best performance for equality matches Must be properly sized for good performance Undersized hash indexes can result in severe performance penalties Range Indexes Range indexes best for range search Can ALTER Unique PK range indexes Default index type for primary key indexes to hash indexes Up-to-date table and column statistics Important for a cost-based SQL optimizer

23 Summary TimesTen is an excellent choice for in-memory analytics in the application tier Correct setup and usage is vital to achieve good performance and easy management OS, configuration, operations, persistence storage, tuning, etc. Use the tools available to make your life easier and get the best results Many more best practices available Visit TimesTen product center on Oracle Technology Network Refer to TimesTen documentation for more information (available online)

37 TimesTen DAC CIMA Set Up How DAC identifies records in TimesTen at task level CIMA CIMA,Exalytics,TimesTen 01/10/

38 TimesTen DAC CIMA Set Up How DAC identifies which records have changed in the warehouse that need to be copied to TimesTen CIMA CIMA,Exalytics,TimesTen Siebel CRM 01/10/

39 Outcome Full warehouse approx 300gb loaded into memory 100x + performance improvement, in some cases much higher Full load took approx 3 hours Incremental nightly copy approximately 6 minutes Achieved huge performance uplift with zero application code changes Enabled previously unachievable analysis, leading to greater knowledge of customers and challenges across the company 100% In-memory Daily load time 6 mins ipad apps roll-out ongoing Zero Application code changes Performance Improvement INTELLIGENCE AND BUSINESS RESULTS CIMA CIMA,Exalytics,TimesTen

40 Feedback It s all a lot better. It s so quick now it s difficult to measure without an atomic stopwatch. UK User I didn t used to use the old dashboards to the extent that I do now- maybe that s partly because I used to get so fed up with the speed that I gave up whereas now it s there at the press of a button UK User Report UK - WAN connection on standard Analytics seconds Outside of UK - Wifi connection on Analytics not possible due to error Outside of UK - Wifi connection on Times Ten In Memory DW 1.1 second via webex CIMA CIMA,Exalytics,TimesTen

41 Deployment Tips In RPD make sure you use correct TimesTen ODBC settings We used DAC to create the table and index scripts INITIAL load: run the table scripts on the TimesTen Server, load the data using the DAC, run the create index scripts on the TimesTen server, update the stats on TimesTen OBIEE Caching: Linux Ram Disk cache into memory! If using Exalytics and LDAP for OBIEE, follow the weblogic admin guide for configuration Keep checking support for Patch updates If any columns are being used to do updates make sure they are indexed. Update the stats constantly especially if you are updating and inserting rows CIMA CIMA,Exalytics,TimesTen 01/10/
