The DB2® server information in LDAP must be kept current. For example, changes to the protocol configuration parameters or the server network address require an update to LDAP.
db2 update ldap ...
Examples of protocol configuration parameters that can be updated include a TCP/IP hostname and service name or port number parameters.
db2 update ldap
node <node_name>
hostname <host_name>
svcename <tcpip_service_name>
