pwxcmd commands that connect to the PowerExchange Logger through the SVCNODE port
PowerExchange user credentials
A client program sends the user ID and password of the PowerExchange user to the PowerExchange Listener or PowerExchange Logger.
The PowerExchange Listener or PowerExchange Logger reads LDAP configuration information from the DBMOVER configuration file.
If you configure PowerExchange to use the Transport Layer Security (TLS) protocol to encrypt communications between PowerExchange and the LDAP server, PowerExchange uses keystore and truststore files to authenticate the LDAP client or server.
LDAP client libraries
The LDAP client libraries provide an interface between the PowerExchange Listener or Logger and the LDAP server.
The LDAP server receives and executes the calls that the PowerExchange Listener or PowerExchange Logger issues to bind the search user, search for the PowerExchange user, and bind the PowerExchange user.
