This section describes what is not supported.
- Not all database clients may be supported. See your Quick Beginnings manual to determine whether DCE directory services is supported
from your DB2 client. Currently, support is only provided for DB2
Client Application Enabler for all UNIX, OS/2, Windows NT, and Windows 95
- A client cannot use DCE Directory Services to connect to a DB2 for OS/2
Version 1 server.
- Only Windows NT or Windows 95 clients can use any or all of the TCP/IP,
APPC, NetBIOS, IPX/SPX, or NPIPE protocols. Only OS/2 clients can use
any or all of the TCP/IP, APPC, NetBIOS, and IPX/SPX protocols. All
supported UNIX clients can only use the TCP/IP and APPC protocols.
- LIST DATABASE (or NODE) DIRECTORY COMMANDS only provide entries from the
local directories and not entries from the DCE directory. You can use
the cdscp show object command in DCE to display the objects.
- When all of the following conditions exist, the owner of the database
manager instance must login to DCE before starting the database manager (using
the db2start command).
- The database manager instance is configured to support DCE directory
services through the dir_type configuration parameter
- The cell directory services object can only be read by explicitly logging
- The DCE directory must be accessed to support either of the
- A transaction manager database (specified by the tm_database
configuration parameter) located on another instance
- A client that cannot support DCE directory services, or is not configured
to use DCE directory services.
|Note:||When performing the DCE login, you should use a principal that has a long
- When using a DDCS Version 2.2 (or earlier) gateway to connect a
client that is using DCE directory services to a DRDA server, you must catalog
the database alias in the gateway's local directory. This database
alias must be the same as the alias on the client and it must represent the
- When using Windows NT, Windows 95, or Windows 98 clients,
DB2DCE.DLL will be used. This file is found in the
bin subdirectory of the sqllib subdirectory. If
the DCE provider is Gradient**, by default the file DB2DCE.GRD is
equivalent to DB2DCE.DLL. If the DCE provider is IBM, the file
DB2DCE.IBM must be copied to DB2DCE.DLL.
