A node name for the DB2 server must be specified when registering the server in LDAP. Applications use the node name to attach to the database server. If a different node name is required such as when the node name is hard-coded in an application, use the CATALOG LDAP NODE command to make the change. The command would be similar to:
db2 catalog ldap node <ldap_node_name>
as <new_alias_name>
To uncatalog a LDAP node, use the UNCATALOG LDAP NODE COMMAND. The command would appear similar to:
db2 uncatalog ldap node <ldap_node_name>
