HiT OLEDB Server/DB2
HiT OLEDB Server/DB2 Developer Edition

HiT OLEDB Server/DB2 (for OLE DB DB2 or mainframe) is Windows client middleware for DB2 SQL access from custom applications and third party products. HiT OLEDB Server/DB2 accepts application SQL commands via ADO v2.x or directly via its object properties and methods. It then translates these into native DB2 SQL for high-performance, communicates with the DB2 server to access, retrieve, and update data. All communication with the DB2 server can also be optionally encrypted and authenticated via SSL v3.0 support. Leveraging the IBM Distributed Relational Database Architecture protocol standard, HiT OLEDB Server/DB2 (for OLE DB DB2 or mainframe) uses native IBM server programs and does not require any additional DB2 server software. HiT OLEDB Server/DB2 supports all Windows 32-bit client platforms including Windows 2000 and NT Server.

HiT OLEDB Server/DB2 supports full SQL functionality for maximum application performance including stored procedures, multiple result sets, and static SQL/packages. Multi-threading and re-entrancy support ensure high performance for client applications. Its unique dbXpress performance feature also significantly speeds applications. HiT OLEDB Server/DB2 can communicate over TCP/IP or SNA connections.

OLEDB provider support includes data source, session, transaction, command, rowset, and error COM objects. (Distributed transactions are supported for TCP/IP connections to the mainframe and will be supported on other platforms when DB2 v7 becomes available.) A complete set of data type mapping between DB2/400 and OLE DB/ADO environments is supported and documented.

HiT OLEDB Server/DB2 database schema support is based on the ANSI SQL92 specification. Schema information retrieved using predefined schema rowsets via IDBSchemaRowset::GetRowset interfaces. Applications can specify simple restrictions, such as returning all the columns in a particular table.

Security is supported via the IDBProperties interface, where applications can request the type of authentication/authorization mechanism they want to use.

Support is included for OLE DB v2.0 connection pooling. ADO v2.0 connection pooling, as an OLE DB v2.0 consumer, is therefore also supported.

The included OLEDB Workshop allows easy data link definition and diagnostics. Additionally, it provides powerful trace and debugging tools to help troubleshoot and optimize application performance, and convenient SQL package management.

HiT OLEDB Server/DB2 Developer Edition (DE) includes the HiT Active Server Page and Visual Basic Toolkits. These contain source code examples for accessing data using ActiveX Data Objects 2.0 (ADO). It significantly cuts application development time by providing developers working ASP code and VB samples to query and update DB2 tables and retrieve DB2 data for redirection to applications. Included source code demonstrates connections using ADO recordsets, executing stored procedures, retrieving table data, inserting table data, and displaying results.

A client OLEDB provider, HiT OLEDB/DB2, is also available.
