Error description

  • When the JDBC/JCC driver receives an invalid packet from the
    server it may become stuck in an infinite client re-route
    loop.
    
    This fix will limit the number of retries to 10 retries and then
    throw the -4228 error.
    

Local fix

  • In SYSPLEX environments set the JDBC driver parameter
    enableSysplexWLB=false

    Fixpack 4.  Download the IBM Data Server Driver for JDBC and
    SQLJ for v9.7 Fixpack 4.
