Most of my work in Tivoli Directory Integrator has been using CSV Files,  LDAP, AD, and DB2 as sources/destination for data occasionally but not often I connect TDI to read/write from a  Domino Database.
This morning I banged my head against the wall for a bit having forgotten one simple step to make this work, so saving this here as much as a note to myself as anything else.
TDI ships with a Notes Connector, but requires a Jar file to be copied from Domino to TDI before it will work, if you are planning on using the Notes Connector make sure you copy NCSO.jar from <dominodata>\domino\java to <tdiprogram>\jars\3rdparty\others and restart TDI.
If you are not using TDI remember both IBM Connections and IBM Lotus Domino both ship with entitlements to TDI, it might be the best free tool you aren’t using.
sounds familiar to me, had the same problem in the past… 😉
This is great stuff, Mitch, thanks for sharing!
