To enable tracing for the Live Universe Connector, follow the below steps:

  1. Go to the conf directory of the Tomcat which has the Live Universe Connector deployed, eg:
    C:\Program Files (x86)\Apache Software Foundation\Tomcat 9.0\conf
  2. Create a new file bo_trace.ini
  3. Add the below lines to the bo_trace.ini (replace <PATHTOLOGSFOLDER> with a path to the desired folder to store the logs:
    size = 494967290; 
    keep_num = -1; 
    sap_trace_level = trace_debug; 
    sap_log_level = log_info; 
    log_dir = "<PATHTOLOGSFOLDER>";

    Note: keep_num = -1; means that logs will never be deleted, leading to the possibility that the logs could use all available disk space. Do not leave it at -1 for an extended period of time.
  4. Next, go to the JAVA options for Tomcat and add the java parameter for the bo_trace.ini:
  1. Windows

    1. If a standalone Tomcat is being used (KBA 2897198) then go to tomcatdir\bin\TomcatXw.exe -> Java tab
      If the SAP BI tomcat is being used, run the program 'Tomcat Configuration' -> Java tab

    2. under the 'Java Options' section, add:
      Eg: -Dtracelog.configfile="C:\Program Files (x86)\Apache Software Foundation\Tomcat 9.0\conf\bo_trace.ini"
    3. Restart Tomcat

  2. Linux
    1. Navigate to tomcatdir/bin
    2. Open
    3. Add the line (or append to if it already exists):
      JAVA_OPTS="$JAVA_OPTS -Dtracelog.configfile="tomcatdir/conf/bo_trace.ini"
      eg: JAVA_OPTS="$JAVA_OPTS -Dtracelog.configfile=/usr/BOP/tomcat/conf/bo_trace.ini"
    4. Save
    5. Restart Tomcat
