ODBC – Typical Applications
� ODBC / CLI user interchangeably– Think of CLI as ODBC ++
� ISV applications– Every database has an ODBC driver – Has been a mainstay for nearly two decades– Open source drivers– Current Perl, Python, PHP, Ruby drivers written to vendor ODBC
libraries
� Popular end user apps– Excel, Access

.NET Data Provider Comparison
� Bridge providers do not have newer data types and f eatures– XML - integration with XmlReader– Decimal Float– Higher timestamp precision– Temporal
� Difficulty in diagnosing problems– Limitations in MS Bridge providers or ODBC / OLE DB interfaces– Connection pooling often an issue
� IBM Visual Studio Addins for DB2 .NET provider only
© 2012IBM Corporation7
DB2 .NET Data Provider
� IBM’s .NET support is designed to operate in the .N ET environment as .NET programmers expect– Our documentation is reference oriented– Documentation also provides best practices / examples for our unique
features
� VS Addins fully leverage rapid application developm ent – VS Addins also exploit IBM unique features
� Current .NET and Visual Studio skills transportable
� Entity Framework is the latest .NET paradigm– Object layer on top of ADO.NET
© 2012IBM Corporation8
VS Addins Summary – VS 2008 / 2010 / VS 2012
� Server Explorer– Enumeration – filtering, Entity Framework designer– View Data, Script– Drag n drop – windows app, web app, Entity Framework– Schema evolution - developers
� Stored Procedures– SQL Procedure designer– SQL keyword highlighting and Intellisense– End to end debugging – merged call stack , step into, run to breakpoint
� XML– XML Schema, generate sample– XML index designer
� Web Services– IIS (ASP.NET)
© 2012IBM Corporation9
JDBC
� JCC (Java Common Client) is IBM’s JDBC driver– Connectivity to DB2 and Informix Data Servers
� Supports SQLJ in addition to JDBC
� Supports type 2 and type 4 – Type 4 – pure Java implementation, uses DRDA protocol– Type 2
• DB2 for z/OS – highly optimized local connectivity• DB2 for LUW local or remote connectivity
– Uses DRDA in-memory if local
� Available as a JAR file – no install necessary
� Embedded in many applications and tools – eg. Data Studio

Integration with OPM
� OPM Extended Insight Feature– Provides end to end performance information
� Need to communicate driver information to OPM serve r– Client side component to aggregate driver information and handshake with
OPM server• Location of OPM server comes from OPM controller
– Extended Insight Client – Data Tools Runtime Client (DTRC)
� DTRC– Jar file to be in classpath for Java based apps– Shared library for non-Java
• Requires location to be specified in db2dsdriver.cfg file– Default location does exist
– Location of controller needs to be configured at each client• V9.7 FP6 and later drivers can determine monitor location from database
© 2012IBM Corporation16
Integration with OPM
� In general, full exploitation of new features requi res driver, EI client and OPM server upgrades– Minimum level for Java is V9.7– Minimum level for ODBC, .NET is V9.7 FP3
� Up and Running focus items– Determine location of OPM server from application database
• Simplifies setup, no controller involved– Auto-load DTRC shared library from fixed location
• Would eliminate any client side setup– Avoid additional client side software install
© 2012IBM Corporation17
Integration with pQ
� pureQuery client optimization offers dynamic -> sta tic conversion for JDBC, ODBC and .NET– Common tooling for managing packages produced through capture
� Also a set of high performance programming APIs for JDBC
� In general, ODBC and .NET enhancements will require a driver upgrade– Minimum level for ODBC is V9.7 FP1– Minimum level for .NET is V9.7 FP6
� In general, JDBC enhancements do not require a driv er upgrade– Minimum level for JCC is V9.5 FP5
© 2012IBM Corporation18
Integration with OCM
� Optim Configuration Manager assists with managing s erver and client configuration and settings– Ability to push down settings to drivers– Ability to control driver behavior based on client info properties
� Similar to OPM EI, there is a client side agent req uired – Data Tools Runtime Client utilized as for OPM EI
� In general, functional improvements often require d river, DTRC and OCM updates– Minimum level for Java is V9.5 FP10, V9.7 FP6, V10.1 – Minimum level for ODBC, .NET is V9.7 FP7, V10.1 FP1
© 2012IBM Corporation19
Why the focus on client packages / drivers
� Latest code levels required for new server feature exploitation– For example, DB2 9.7 FP3a drivers required for new z/OS V10
datatypes– V9.7 FP6 required for LUW V10.1 new datatypes
� Latest code levels required for API specific featur es– For example, .NET 4.0 or Visual Studio 2010 require DB2 V9.7 FP4– Visual Studio 2012 beta was only on V9.7 FP6
• GA in V10.1 FP2, no GA support in V9.7
� Larger client packages require more effort to upgra de– Many customers still at V8.2 DB2 Client– Approx 130 SQL packages to rebind in Client
• A rebind required with each FP upgrade
© 2012IBM Corporation20
Client Packages
� What has changed - Customer Feedback– Clients are too big
• From both a size and complexity point of view• Unnecessary configuration and migration steps• Focus now on “collections” of drivers vs clients
– DB2 client instance• Requires migration version to version – binary file• Difficult to deploy to multiple similar workstations• Root privileges required on LU platforms
– Client SQL Packages• Requires rebind, thus potentially a server outage
– Added support for Informix• Rename from DB2 -> IBM Data Server
© 2012IBM Corporation21
Client Packages
� IBM Data Server Driver Package (ds driver – V9.5 FP3 )– No client database instance / directory– Includes JCC, ODBC / CLI, Open Source, CLPPlus– On Windows, includes OLE DB and .NET– Introduced db2dsdriver.cfg file for configuration– Best practice for enterprise deployment – all servers
� IBM Data Server Driver for JDBC and SQLJ (JCC – V8)– Standalone download of Java support only– Packaged with many other deliverables
• Data Studio, Websphere, etc.
© 2012IBM Corporation22
Client Packages
� IBM Data Server Runtime Client– No additional APIs above ds driver (except load)– Adds the DB2 CLP, plus database directory (client instance)– Includes many DB2 LUW specific utilities– Approx 3x the size of ds driver
� IBM Data Server Client– Runtime client plus all development and admin tooling– Approx 10x the size of ds driver
� DB2 Connect Personal Edition (software)– Client plus DB2 Connect PE license– Not generally recommended
© 2012IBM Corporation23
Deployment Best Practices
� Runtime deployment– ds driver highly recommended– Lightest runtime focused client package– Common client config across multiple levels– No migration to move to newer levels
• No database directory• Simple in-place code upgrade
© 2012IBM Corporation24
Client Availability
� Strong focus on downward compatibility– Client upgrade independent of server upgrade
� Allows new client levels to be installed to exploit latest API enhancements– Traditionally upgrades driven by server side– Recently seeing more upgrades driven by API and tooling side
© 2012IBM Corporation25
Function Rollout Overview
