DB2 Connect User's Guide

Chapter 3. Updating Database Directories

DB2 Connect uses the following directories to manage information about databases that it connects to:

• The node directory, which contains network address and communication protocol information for every DRDA server that DB2 Connect accesses.

• The database connection services (DCS) directory, which contains information specific to DRDA server databases.

• The system database directory, which contains name, node, and authentication information for every database that DB2 Connect accesses.

Notes:

1. Before updating these directories, you should configure communications on the DRDA server and workstations. This is described in DB2 Connect Personal Edition Quick Beginnings, and DB2 Connect Enterprise Edition Quick Beginnings.

2. Note that on OS/2, Windows 95, and Windows NT, database directories can be updated using the DB2 Universal Database Client Configuration Assistant (CCA). On Windows 3.1 and Windows for Workgroups 3.11, the database directories can be updated using the Data Sources Setup tool.

   On all other platforms the database directories must be updated using the DB2 Command Line Processor (CLP).

3. "Updating the Directories" provides example command syntax. For further information refer to the Command Reference.

4. If you are using DCE, for each DRDA server database that you connect to, you must update these directories or store equivalent information in a global DCE directory. For more information about DCE, see Appendix C. "Using DCE Directory Services" and the Administration Guide. This chapter assumes that you are not using DCE Directory Services.
