DB2 Connect V9.1 comes packed with many new exciting features. Please read the announcement letter for a complete list of the new functionality built into the latest version of this product. Application development enhancements
DB2 Connect V9.1 provides numerous enhancements that simplify database application development. Enhancements include a new Developer Workbench, enhanced functionality for Visual Studio 2005 and DB2 .NET Data Provider. Client support for trusted connections to DB2 for z/OS databases
DB2 CLI and DB2 Driver for JDBC and SQLJ now support making trusted connections to DB2 data servers that support trusted contexts. DB2 .NET Data Provider enhancements and support for the .NET Framework 2.0
The DB2 .NET Data Provider now supports the Microsoft™ .NET Framework V2.0 and has additional new features to help you develop more powerful .NET applications. Developer Workbench replaces the Development Center
The Development Center from DB2 UDB for Linux, UNIX, and Windows V8 is replaced in DB2 V9.1 by an Eclipse based tool called Developer Workbench. The Developer Workbench includes functionality comparable to the Development Center. Java routine class loader enhancements
Application developers who develop Java routines can now utilize multiple Java classes that have the same name by including them in separate JAR files and by explicitly identifying them in routine create statements. Client and connectivity enhancements
DB2 Connect V9.1 client and connectivity enhancements include new features such as IPv6 communication protocol support, new support for running ODBC and CLI applications without a DB2 client, and connection timeout support. These enhancements and others ensure that you have flexible and effective methods of accessing data from client systems and applications. Connection timeout support for database applications
You can now set a connection timeout value for DB2 database connections in .NET, CLI, ODBC, and OLE DB applications. Setting a connection timeout is useful in case the database server is inaccessible. In this situation, it can take a long time for connection requests to fail and return. Setting a connection timeout enables you to set a limit to the amount of time your applications should wait for a connection. DB2 Runtime Client enhancements (Windows)
Prior to Version 9, there were two similar clients on Windows, the DB2 Runtime Client and the DB2 Run-Time Client Lite. The Version 9 Runtime Client on Windows has evolved from the Version 8 Run-Time Client Lite. New support for running ODBC and CLI applications without a DB2 client
The DB2 Driver for ODBC and CLI can now be installed and used to run ODBC and CLI applications without a DB2 client. When the driver is installed without a DB2 client, it still provides runtime support for ODBC and CLI, and it now also provides connectivity for ODBC and CLI applications. Various install options are available for the IBM DB2 Driver for ODBC and CLI
You can install the driver on a machine that already has a DB2 client installed. You can have multiple installations of this driver on a single machine. Being able to install the DB2 Driver for ODBC and CLI without a DB2 client reduces distribution size, installation footprint, and memory footprint. Installation, migration, and fix pack considerations
With new features and enhancements such as coexistence of multiple DB2 Connect versions and fix packs on Windows, manual installation enhancements, and support for concurrent copies of DB2 Connect servers on Linux and UNIX, DB2 Connect V9.1 allows your IT staff to spend more time supporting business goals instead of installing and configuring database systems. DB2 Connect can be installed using a non administrator user ID (Windows)
Anyone who does not want to use an administrator ID when installing DB2 Connect on Windows, now has another option. You can use the Windows operating system elevated privileges feature to perform the installation with a Windows Power User ID or a Restricted User ID. Installation and coexistence of multiple DB2 Connect versions and fix packs
DB2 V9 on Windows introduces the ability to install multiple DB2 Connect Servers and client copies on the same system. Each DB2 Connect installation copy can either be at the same level or at a different level of DB2 Connect. On Linux and UNIX, this support does not require the use of an alternate fix pack. When installing DB2 Connect on a machine that already has a DB2 product copy installed, you can install a new DB2 copy or work with and update an existing.
