DB2 Connect User's Guide

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 host or AS/400 database server that DB2 Connect accesses.
• The database connection services (DCS) directory, which contains information specific to host or AS/400 database 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 host or AS/400 database server and workstations. For more information, refer to the Installation and Configuration Supplement.

2. On OS/2 and Windows 32-bit operating systems, database directories can be updated using the DB2 Universal Database Client Configuration Assistant (CCA).

   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 host or AS/400 database 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 D, Using DCE Directory Services and the Administration Guide. This section assumes that you are not using DCE Directory Services.
