  • 1.  SSL errors with DB2 community edition and dotnet client

    Posted 09/23/24 05:03 PM

    I have a dotnet 8 application using the Net.IBM.Data.Db2 nuget package 8.0.0.300 talking to DB2 community edition v11.5.8.0. Client is running on Windows 11. Server-side certificate, keydb, and stash have been configured according to samples in DB2 documentation. Client-side is passing the certificate (no keydb or stash.) I get intermittent failures; the db2diag.log for a failing run is attached. There are no indications of problems on the server side.

    If this fragment of db2diag.log is from client then it appears that server replied badly:
