with "A remote named pipe node."
The database manager creates the node directory when the first node is cataloged (that is, when the first CATALOG...NODE command is issued). On a Windows client, it stores and maintains the node directory in the instance subdirectory where the client is installed. On an AIX® client, it creates the node directory in the DB2 installation directory.
List the contents of the local node directory using the LIST NODE DIRECTORY command.
If directory caching is enabled (see the configuration parameter dir_cache in the GET DATABASE MANAGER CONFIGURATION command), database, node, and DCS directory files are cached in memory. An application's directory cache is created during its first directory lookup. Since the cache is only refreshed when the application modifies any of the directory files, directory changes made by other applications might not be effective until the application has restarted.
To refresh the CLP's directory cache, use the TERMINATE command. To refresh DB2's shared cache, stop (db2stop) and then restart (db2start) the database manager. To refresh the directory cache for another application, stop and then restart that application.
