Diagnostics
If you have a problem, perform the following steps to gather diagnostics:
  1. On Windows, copy ptt.ini to eclipse.ini and edit eclipse.ini. On Linux, edit ptt.ini. On macOS, edit Eclipse.app/Contents/Eclipse/ptt.ini:
    1. Change the following line:

      -Dorg.apache.soap.debug=false

      To this:

      -Dorg.apache.soap.debug=true
       
    2. Change the following line:

      -Djavax.net.debug=

      To this:

      -Djavax.net.debug=all
       
  2. Edit TraceSettings.txt (on macOS, Eclipse.app/Contents/Eclipse/TraceSettings.txt):
    1. Change the following line:

      #*=all=enabled

      To this:

      *=all=enabled
       
  3. Open a command prompt or terminal and start PTT as follows:

    Windows:
    C:\Users\name\> cd Downloads\PTT
    C:\Users\name\Downloads\PTT> .\eclipsec.exe -debug -consoleLog > ptttrace.log 2>&1

    macOS:
    % cd Downloads/PTT/Eclipse.app/Contents/MacOS
    % ./ptt -debug -consoleLog > ptttrace.log 2>&1

    Linux:
    $ cd Downloads/PTT
    $ ./ptt -debug -consoleLog > ptttrace.log 2>&1
  4. Reproduce the problem and close PTT
  5. Send ptttrace.log and adminclient.log (on macOS, the files are in ./Eclipse.app/Contents/MacOS/)
Known Issues
  1. To connect using TLS 1.2, follow the instructions for configuring administrative clients: https://www.ibm.com/support/knowledgecenter/SSAW57_9.0.0/com.ibm.websphere.nd.multiplatform.doc/ae/tsec_config_strictsp300.html. PTT dynamically generates files in a directory under the installation folder after the first connection is attempted. For example: configuration/org.eclipse.osgi/bundles/5/1/.cp/etc/. The TLSv1.2 changes are only needed in the ssl.client.props file.
