IBM and other software vendors have implemented DRDA support into database systems, such as IBM DB2, and database tools on a wide range of operating systems. DRDA is an open, published, and widely-supported protocol, which requires no additional license for development. This makes DRDA appealing to independent software vendors (ISVs), solution providers, large corporate development groups, as well as their customers.

The Microsoft® OLE DB Provider for DB2 is implemented as an IBM Distributed Relational Database Architecture (DRDA) application requester, which means it connects to popular DRDA-compliant DB2 systems.

The Microsoft OLE DB Provider for DB2 can access the following DB2 systems through SNA LU6.2 using Microsoft Host Integration Server 2000:

• DB2 for MVS Version 4 Release 1 (V4R1) or later
• DB2 for OS/390 Version 5 Release 1 (V5R1) or later
• DB2 for OS/400 (DB2/400) Version 3 Release 2 (V3R2) or later

The Microsoft OLE DB Provider for DB2 can access the following DB2 systems directly using TCP/IP:

• DB2 for OS/390 Version 5 Release 1 (V5R1) or later
• DB2 for OS/400 (DB2/400) Version 4 Release 2 (V4R2) or later
• DB2 Universal Database for Windows NT Version 5 Release 2 (V5R2) or later
• DB2 Universal Database for AIX Version 5 Release 2 (V5R2) or later

Note that DB2 for OS/400 (DB2/400) Version 4 Release 3 (V4R3) requires that PTF SF99103 be applied. DB2 for OS/400 (DB2/400) Version 4 Release 4 (V4R4) requires that PTF SF99104 be applied.

IBM DB2 with DRDA support is available on a variety of other platforms. The OLE DB Provider for DB2 has not been tested with these other implementations.
