  • 1.  Liberty and DB2 with SSL

    Posted Fri May 24, 2024 08:12 AM

    Hi, 

    does anyone use DB2 connections from liberty with SSL? We followed the instructions from IBM support at:

    Connecting from Liberty for z/OS to Db2 with the type 4 JDBC Driver over SSL (ibm.com)

    but always get an error DSRA0010E SQL Szte = 08001, Error Code = -4499 and message from org.eclipse.persistence.exceptions.DatabaseException saying "Caught NoSuchAlgorithmException while doing SSL Connection". We do not see any message in DB2.

    Does anybody have an idea or might share his/her experience?

    The best way to diagnose SSL exceptions occurring in Liberty is using JSSE trace, this can be enabled using the following system property set in the JVM profile

    -Djavax.net.debug=all

    See this page for some more details https://www.ibm.com/docs/en/sdk-java-technology/8?topic=troubleshooting-debugging-utilities

    Hi Phil,

    thank you for the link and the debug option.
    Currently the problem seems to be that the JDBC-driver being used does not support Semeru 17.

    So we have to install a new JDBC-driver and check if that works.

    Regards
    Helmut
