DB2 Client and Driver Some Highlights DB2 9.1 FP1 DB2 9 for z/os LOB Progressive Streaming for locator Values IBM Data Server Provider for.net support of trusted context FP2 DB2.NET Data Provider is enhanced and support is added for the.net Framework 2.0. FP5 Secure Sockets Layer (SSL) protocol is supported by database clients. DB2 9.5 Informix client and driver support, new name IBM Clients/Drivers Java driver DB2 9 for z/os Trusted Context support FP1 IBM Data Server Driver for JDBC and SQLJ Version 4.0 includes a number of JDBC 4.0 capabilities. To use these capabilities, you need an SDK for Java, Version 6. FP2 Secure Sockets Layer (SSL) protocol is supported by database clients. FP3 Client-side support for DB2 for z/os Sysplex capabilities in IBM data server clients and non-java data server drivers that have a DB2 Connect license. Dec. 2008 The IBM Data Server Drivers now include application header files for open source drivers, support OLE DB, and can use a new configuration file. FP4 db2drdat is shipped with Data Server driver Package from 9.5 FixPack 4 and higher. 4
DB2 Client and Driver Some Highlights DB2 9.7 Deprecation Control Center and DB2 Admin Server Tools FP2 Includes DB2 Command Line Processor Plus (CLPPlus) for dynamically creating, editing, and running SQL statements and scripts. Supports aliases in db2dsdriver.cfg file. FP2 IBM Data Server Driver provides registerdsn, a command line utility to register ODBC DSN on Windows ODBC Driver Manager. (This is key for IBM Data Server Driver adoption for Microsoft web servers that have ADO.Net, OLE-DB and ODBC applications installed.) FP2 32 bit drivers included in 64 bit package Starting in Version 9.7 Fix Pack 2, the 32-bit versions of IBM Data Server Provider for.net are included in the 64-bit driver package. When you install the 64-bit drivers, the 32-bit drivers are also installed, in a separate directory named, sqllib\bin\netf20_32. 5
DB2 Client and Driver Some Highlights DB2 9.7 continued FP3 Full support for db2dsdriver configuration file extended to IBM data server clients for CLI and open source applications Starting in Version 9.7 Fix Pack 3, the db2dsdriver.cfg configuration file can be used to retrieve all database connection information and properties for CLI and open source applications that use IBM Data Server Client and IBM Data Server Runtime Client. In previous releases, IBM Data Server Client and IBM Data Server Runtime Client used the db2dsdriver.cfg configuration file to retrieve only Sysplex-related settings. In Version 9.7 Fix Pack 3 and later, CLI and open source applications that use IBM Data Server Client and IBM Data Server Runtime Client can use information from the db2dsdriver.cfg configuration file to connect to a supported database. Other applications that use IBM Data Server Client and IBM Data Server Runtime Client, such as.net applications or applications that use embedded SQL, can retrieve only Sysplex-related settings from this configuration file. Starting in Version 9.7 Fix Pack 3, IBM Data Server Provider for.net supports DB2 Universal Database Version 10 for z/os which includes support for client disable dynamic statement cache, extended indicators, Timestamp with timezone, and New explain features. FP3a Current Fix Pack recommended for DB2 10 for z/os support I also recommend this Fix Pack as the minimum level for IBM Data Server Driver Package adoption 6
What s new for DB2 Clients and Drivers?

DB2 z/os Lab Strategic Goal: Avoid the use of DB2 Connect Gateways IBM Data Server Drivers and Clients as requesters: The IBM strategy is to remove the reliance on the DB2 Connect modules and replace DB2 Connect with the IBM Data Server Drivers or Clients. While DB2 Connect licenses (in the form of DB2 Connect license files) are still required, you can replace DB2 Connect modules with the IBM Data Server Drivers or Clients and receive equivalent or superior function. In addition, you can reduce complexity, improve performance, and deploy application solutions with smaller footprints for your business users. With DB2 for LUW Version 9.5 FixPack 3 or FixPack 4 you can implement the DRDA AR functions for your distributed applications with varied degrees of granularity. Instead of the current function and large footprint of DB2 Connect, you can choose from the IBM Data Server Drivers, the IBM Data Server Runtime Client, and the IBM Data Server Client. The IBM Data Server Drivers include: IBM Data Server Driver for JDBC and SQLJ IBM Data Server Driver for ODBC and CLI IBM Data Server Driver Package Source: IBM Redbook - DB2 9 for z/os: Distributed Functions SG24-6952 Section 2.3 8
DB2 z/os Lab Strategic Goal: Elimination of DB2 Connect Gateways Elimination of DB2 Connect Gateways Provides: Simplifies Network Topology Application server direct connection to DB2 z/os Improves Performance Elimination of network hop and DB2 Connect Gateway routing Improves Availability DB2 Connect Gateway clustering eliminated Simplifies Code Maintenance Update code of clients/drivers only and no coordination of gateway code changes Just Add DB2 Connect License File to Client or Driver Be careful when considering the elimination of DB2 Connect Gateways that you don t violate current DB2 Connect licensing agreement. If you company has any other version than DB2 Connect Unlimited Edition, I would suggest contacting your IBM Sales Specialist to verify compliance Multi-transport models such as Tuxedo, WebLogic, and Encina still require a middle-tier DB2 Connect Server. 9
SQL Packages Adoption of IBM Data Server Drivers reduces the needs for client package binds Dynamic SQL packages standardized between CLI,.NET and JCC in V8 Only changed once since then (driven by z/os unique change) Changes documented: http://www.ibm.com/developerworks/wikis/display/db2/db2+and+.net +FAQs#DB2and.NETFAQs-ChangesinCLI%2F.NETandJDBCpackages Changes in CLI /.NET and JDBC packages The packages were standardized in V8 of the DB2 LUW and DB2 Connect clients. The following is the change history of these packages: Dynamic packages SYSSHxyy, SYSSNxyy, SYSLHxyy, SYSLNxyy: V8 GA - created SYSSTAT misc static statements: V8 GA - created V9.1 FP2, V9.5 GA - added additional sections for Jcc z/os type 2 Rebinds only need to happen when upgrading across one of the change points listed above. For example, upgrading fro V8 GA to V9.1 GA would not require a rebind. However, any upgrade from V9.1 FP1 would technically require a rebind because the SYSSTAT package changed. However, the change affected the Jcc z/os type 2 driver only, thus CLI and.net, and other servers, need not rebind as they will be unaffected by the change.

IBM and Continues Improvement for Microsoft.Net If the failure occurs on the first SQL operation in a transaction, and seamless failover is enabled (and applicable), the client can replay the failed SQL operation as part of Automatic Client Reroute (ACR) processing. If the connection is successful, no error is reported to the application. If ACR is enabled, an application that encounters a connectivity failure is routed to another member of the Sysplex. If seamless failover is disabled or not applicable, the error SQL30108N is returned to the application. To perform ACR, the client must use a TCP/IP connection and have a DB2 Connect license. The following Version 9.5 Fix Pack 3 or later clients provide support for ACR: IBM Data Server Client, IBM Data Server Runtime Client, IBM Data Server Driver Package Automatic client reroute settings in the db2dsdriver.cfg configuration file enableacr: Specifies whether the ACR feature is on (true) or off (false). This setting defaults to true when transaction-level load balancing is enabled (the enablewlb setting is true). If ACR is disabled, any other settings for ACR are ignored. enableseamlessacr: Specifies whether the ACR with seamless failover feature is on (true) or off (false). If ACR is enabled and the target server is DB2 for z/os, seamless ACR is enabled by default. If the target server is not DB2 for z/os, this setting is ignored, and seamless ACR is not supported.

DB2 9 for z/os: Distributed Functions My favorite and a MUST have! DB2 for z/os Distributed Data Facility (DDF) is a built-in component that provides the connectivity to and from other servers or clients over the network. DDF is a full-function DRDA-compliant transaction monitor which, equipped with thread pooling and connection management, can support very large networks. Different z/os workload management priorities can be assigned to different, user-specified classes of DDF-routed application work. In this IBM Redbooks publication, we describe how to set up your DDF environment and how to deploy the DDF capabilities in different configurations, including how to develop applications that access distributed databases. www.redbooks.ibm.com/abstracts/sg246952.html 60
