6 DB2 Analytics Accelerator Usage scenarios How organizations leverage the Accelerator today Rapid acceleration of Existing Business Critical Queries If the data is analyzed on the mainframe Performance improvements and cost reduction while retaining z Systems security and reliability Accelerate existing workload Reduce IT sprawl Reduce IT sprawl for analytics If the data is offloaded to a distributed data warehouse or data mart Simplify and consolidate complex infrastructures, low latency, reliability, security and TCO Derive business insight from z/os transaction systems If the data is not being analyzed yet Derive new business insight Include external & historical data Improve access to historical data and lower storage costs If the analysis is based on a lot of historical data One integrated, hybrid platform, optimized to run mixed workload Performance improvements and cost reduction Simplicity and time to value 6
7 Agenda Value Proposition and Use Cases Query Acceleration High Performance Storage Saver In-database transformations In-database Analytics High Availability configurations DB2 Analytics Accelerator Loader V2.1 Summary 7
8 Halkbank Case Study Halkbank extends banking services on social and mobile channels securely and cost-effectively We wanted to improve the performance for complex analytic queries both in order to support rapid and accurate decision making, and in order to meet deadlines for regulatory reporting, where we face penalties of tens of thousands of dollars for late reporting. We expect to be able to move 70 percent of our queries to DB2 Analytics Accelerator, accelerating queries, reducing our DB2 licensing costs on the mainframe, and freeing up processing resources for other workloads. -- Cenk Niksarlı, Head of IT Infrastructure at Halkbank 8
9 Swiss Mobiliar Case Study and Video Swiss Mobiliar accelerates 50% of queries by a factor of 100 Case Study: Video: DB2 Analytics Accelerator makes it possible for us to execute 90% of our queries 25x faster, and 50% of them 100x faster Queries that used to take five hours to complete are now processed in just 20 seconds in the optimized mainframe environment and we can run them any time, day or night, with no interruption to our production systems on the mainframe. -- Thomas Baumann, IT Performance Architect at Swiss Mobiliar 9
10 Banca Carige Case Study and Video Providing superior customer service on a secure platform Case Study: Video: DB2 Analytics Accelerator is key in our vision to provide the right level of data analysis to all users in the bank and possibly outside the bank. By using DB2 Analytics Accelerator, we expect to reach... all criteria we had in mind and create greater benefits for our users because our data are not moved Daniel Cericola, IT & Governance at Banca Carige 10
11 Swiss Re Case Study and Video Speeding high-level decision making that boosts the bottom line Case Study: Video: Our users are getting their reports as much as 70 percent faster reports that took 10 hours are now available the same day, so user satisfaction has increased dramatically, says Estermann. Because those reports contain key analytics that guide pricing and decision making across our lines of business, the solution has the potential to sharpen the company s competitive edge moving. -- Reto Estermann, Director, Information Technology at Swiss Re 11
12 Agenda Value Proposition and Use Cases Query Acceleration High Performance Storage Saver In-database transformations In-database Analytics High Availability configurations DB2 Analytics Accelerator Loader V2.1 Summary 12
13 High Performance Storage Saver Storing historical data in Accelerator only Query from Application to either Active only or Active and Historical Active Part #1 Part #1 No longer present on DB2 Storage Part #2 Part #3 Part #4 Part #5 Part #6 Part #7 Historical 13 Support for partitioned-by-range tables, for example: Time-based partitions, where only the recent partitions are used in a transactional context (frequent data changes, short running queries), but the entire table is used for analytics, regulatory/audit purposes, etc. (data intensive, complex queries)
14 Agenda Value Proposition and Use Cases Query Acceleration High Performance Storage Saver In-database transformations In-database Analytics High Availability configurations DB2 Analytics Accelerator Loader V2.1 Summary 14
15 In-database transformation and multi-step processing DB2 Analytics Accelerator introduces Accelerator-Only tables to store intermediate or final results of data transformation or multi-step processes Accelerator-Only tables enable complex data transformations taking place on DB2 Analytics Accelerator, called In-database transformation Accelerator-Only tables enable intermediate and final results of reporting or other processes to be generated and stored on DB2 Analytics Accelerator, called Indatabase multi-step processing 15 Advantages: Accelerate in-database data transformations and data movement processes Reduced need of data movement processes to other platforms for data transformation purposes Enables multi-step reporting on the Accelerator Saves disk space and CPU cost on z Systems currently used for transformations and reporting steps Allow data preparation steps for data mining and other advanced analytics to execute on the Accelerator Store a set of data in DB2 Analytics Accelerator only, not on DB2 for z/os, without using the High Performance Storage Saver functionality
16 Introducing Accelerator-only table type in DB2 for z/os Creation (DDL) and access remains through DB2 for z/os in all cases Non-accelerator DB2 table Data in DB2 only Table 1 Accelerator-shadow table Data in DB2 and the Accelerator Table 2 Table 2 Accelerator-archived table / partition Empty read-only partition in DB2 Partition data is in Accelerator only Accelerator-only table (AOT) Proxy table in DB2 Data is in Accelerator only Table 3 Table 4 Table 3 Table 4 16
17 Accelerator-only tables Technical basics AOTs are created and dropped using DB2 DDL statements (CREATE; DROP) Accelerator must be started QUERY ACCELERATION behavior may have any value during CREATE/DROP Syntax: CREATE TABLE MYTABLE (...) CCSID ccsid IN ACCELERATOR <ACCEL1>; DROP TABLE MYTABLE; Recommended to create a database in DB2 to be used for the AOTs CREATE TABLE MYTABLE (...) CCSID ccsid IN ACCELERATOR <ACCEL1> IN DATABASE MYDB; Usual authorization necessary to create objects in database SELECT and INSERT/UPDATE/DELETE operations using AOTs can only run on the Accelerator QUERY ACCELERATION behavior must be set to ENABLE/ELIGIBLE/ALL Accelerator-shadow tables, Accelerator-archived tables and other AOTs can be used in the same statement Dynamic and static SQL can be used with AOTs 17
18 Accelerator-only tables Technical basics INSERT FROM SELECT into an AOT Can only run on the accelerator All tables in the SELECT must reside in the accelerator Accelerated shadow DB2 tables Archive tables AOTs QUERY ACCELERATION behavior must be set to ENABLE/ELIGIBLE/ALL Cross-Loader to load data from AOTs into DB2 for z/os Different table names 18
19 Performance INSERT from SELECT Up to 95% better elapsed time and negligible CPU time in DB2 for INSERT FROM SELECT into accelerator-only tables for large amount of data 600 Class 2 CPU Time 500 Class 2 CPU Time (Lower is Better) # Rows in MIll CL2CPU_DGTT CL2CPU_PBG CL2CPU_IDT 19 19
