Tracer Troubleshooting

Trace only one requestor session per operator and node

Do not attempt to start the Tracer when another requestor session on the same PRPC node, using the same Operator ID, is running the Tracer.

Turn Off HTTP compression

Ordinarily, PRPC uses HTTP compression to reduce the length of text messages sent to Internet Explorer. HTTP compression is also used in SOAP messages. This may complicate Tracer debugging, as it is difficult to interpret the messages.

To disable HTTP compression, edit the prconfig.xml file or Dynamic System Setting and adjust the value of the Tracer setting enable-compression setting to false. This change takes effect the next time your system starts.

Reset this value to enable compression when debugging is complete.

Domain Name Service lookups required

In some PRPC installations, the ClientHostName value appears only as a numeric Internet Protocol address. The true ClientHostName is visible only when the application server is enabled to perform Domain Name Server lookups:

• For Tomcat-based systems, set the parameter enableLookups (in the server.xml file) to "true" to allow DNS lookups.
• For Oracle Weblogic, add the parameter ReverseDNSAllowed="true" to the config.xml file to allow DNS lookups.
