  • 1.  Re-Generate SSL Certificates

    Posted Wed August 26, 2020 04:10 AM

    Hi

    We have DB2 Warehouse MPP deployed locally with docker and after upgrade to 11.5.4.0-CN1

    we get error message in Web Console:

    Warning: The console is unable to connect to the database. Common reasons are that the target database is offline or the console is unable to connect to the SSL port. To diagnose the problem, use the console to check the system status. If necessary, consult the Db2 logs.

    and SSL connection to DB is failing

    port 50001 is accessible everywhere

    Any help please?

    [jcc][t4][2030][11211][4.27.25] A communication error occurred during operations on the connection's underlying socket, socket input stream, or socket output stream. Error location: Reply.fill() - socketInputStream.read (-1). Message: Connection reset. ERRORCODE=-4499, SQLSTATE=08001 Connection reset Connection reset

    non-SSL is working correctly

    Hi
    I recommend this way: https://supportcontent.ibm.com/support/pages/node/6262963


    After creating PMR they give me link to new way of regenerating SSL but at this moment link broken
    https://www.ibm.com/support/knowledgecenter/SSCJDQ/com.ibm.swg.im.dashdb.doc/generating_ssl.html

    but if you using this approach you need additional steps on all clients
