    TimesTen Replication fails with TT16060

    user10657233
      We have two RHEL 6.2 servers (175-15-1 and 175-15-3) which have TimesTen Release 11.2.1.9.2 installed. We have a bunch of tables in TimesTen which are replicated("Transmit Durable") in both ways. Both 175-15-1 and 175-15-3 are subscriber and master for each other. Each host has multiple network interfaces. To make sure TimesTen uses a specific network interface, there is route configuration with the replication scheme.

      Replication Route Information
      -----------------------------
      Replication Scheme ROOT.175-15-1
      Route Master I167 on 175-15-1 -> Subscriber I167 on 175-15-3
      Master (sending)
      Pri Interface
      01 y.y.y.y
      Subscriber (receiving)
      Pri Interface
      01 x.x.x.x

      Replication Scheme ROOT.175-15-3
      Route Master I167 on 175-15-3 -> Subscriber I167 on 175-15-1
      Master (sending)
      Pri Interface
      01 x.x.x.x
      Subscriber (receiving)
      Pri Interface
      01 y.y.y.y

      The output of "ttrepadmin -showstatus" says that replication peers are connected.

      For some reason, replication does not seem to work. The following are visible in the TimesTen logs. The same logs are printed on both hosts.

      We thought firewall could be a problem. However, even after disabling the firewall, same errors are thrown.

      What could be the cause of the problem? Thanks for an answer.

      If there are any debug logs that can be enabled to diagnose the problem, please let us know.
