Load Balancer Troubleshooting

Load Balancer Troubleshooting

Load balancer configuration issues might impact the Dashboard display. If you receive an error that the Dashboard is not available, perform the following troubleshooting steps to determine the correct load balancer IP addresses.
  1. For
    B2B Data Exchange
    9.6.1 or 9.6.2, in the directory
    <
    DX
    InstallationDir>\apache-tomcat-7.0.55\shared\classes\
    , find the log file named
    log4j-debug.xml
    and rename it to
    log4j.xml
    .
    For
    B2B Data Exchange
    10.0, in the directory
    <
    DX
    InstallationDir>\tomcat\shared\classes\
    , find the log file named
    log4j-debug.xml
    and rename it to
    log4j.xml
    .
  2. Restart the
    B2B Data Exchange
    services.
  3. For
    B2B Data Exchange
    9.6.1 or 9.6.2, to determine the virtual Dashboard IP stack, in the directory
    <
    DX
    InstallationDir>\apache-tomcat-7.0.55\logs\
    , examine the log file named
    localhost_access_log.<date>.txt
    . Find the entry for the Dashboard authentication IPs, such as the following:
    192.108.177.219 - - [27/Feb/2015:11:24:12 -0500] 'POST /dx-dashboard/rdTemplate/rdGetSecureKey.aspx HTTP/1.1' 302 189
    For
    B2B Data Exchange
    10.0, to determine the virtual Dashboard IP stack, in the directory
    <
    DX
    InstallationDir>\tomcat\logs\
    , examine the log file named
    localhost_access_log.<date>.txt
    . Find the entry for the Dashboard authentication IPs, such as the following:
    192.108.177.219 - - [27/Feb/2015:11:24:12 -0500] 'POST /dx-dashboard/rdTemplate/rdGetSecureKey.aspx HTTP/1.1' 302 189
  4. For
    B2B Data Exchange
    9.6.1 or 9.6.2, open the configuration file
    <
    DX
    InstallationDir>\apache-tomcat-7.0.55\shared\classes\dx_dashboard_configuration.xml
    .
    For
    B2B Data Exchange
    10.0, open the configuration file
    <
    DX
    InstallationDir>\tomcat\shared\classes\dx_dashboard_configuration.xml
  5. Locate the
    AuthenticationClientAddresses
    property in the configuration file. Add the Dashboard IPs separated by commas to the
    AuthenticationClientAddresses
    property.
