Chapter 2. Connecting DB2 for OS/390 in a DRDA Network

DB2 for OS/390 Version 5 is the IBM relational database management system for OS/390 systems. This chapter does not address earlier releases. See Chapter 1. "Connecting DB2 for MVS/ESA in a DRDA Network".

This chapter describes how to connect DRDA Application Requesters (such as DB2 Connect Version 5) to a DB2 for OS/390 Version 5 Application Server, and how to set up DB2 for OS/390 Application Requesters to communicate with DRDA Application Servers such as DB2 Universal Database Version 5 on other systems. Throughout this chapter "DB2 for OS/390" refers to DB2 for OS/390 Version 5.

The primary emphasis of the information in this chapter is on connecting unalike DRDA systems to DB2 for OS/390 using SNA network connections. However, DB2 for OS/390 Version 5 has also introduced support for database communications using native TCP/IP connections (not using AnyNet), and some discussion of using TCP/IP connections is also included. For more detailed information about using setting up and using TCP/IP connections, please refer to DB2 for OS/390 Version 5 Installation Guide, and DRDA Support for TCPIP with DB2 for OS/390 Version 5 and DB2 Universal Database Version 5.

For more information about connecting two DB2 for OS/390 systems, or more detailed information describing how to define DRDA connections to DB2 for OS/390, see the discussion of connecting distributed database systems in the DB2 for OS/390 Administration Guide.

Notes:

1. With the AnyNet Feature of VTAM Version 4 Release 2, you can run APPC over a TCP/IP network. The AnyNet Feature consists of AnyNet/MVS, which runs in a host, and AnyNet/2, which runs in a workstation and is downloaded from the host. Any APPC application is accessible to end users in a TCP/IP network without change to the application. Using APPC over TCP/IP, an application program on OS/390 can communicate with another APPC application program running with AnyNet APPC over TCP/IP on another system. See VTAM AnyNet Feature for V4R2 Guide to SNA over TCP/IP for more information.

2. This chapter does not contain any information about using DCE.
