Use Tracer best practices to make tracing easier and more efficient.
Trace only one requestor session per operator and node
Do not attempt to start the Tracer when another requestor session on the same Pega Platform node is using the same Operator ID, or is running the Tracer.
Turn off HTTP compression
Ordinarily, Pega Platform uses HTTP compression to reduce the length of text messages sent to Internet Explorer. HTTP compression is also used in SOAP messages. This might complicate Tracer debugging because compression makes it difficult to interpret the messages.
To disable HTTP compression, set the value of the prconfig/enable-compression/default Tracer dynamic system setting to false and its owning ruleset to Pega-Engine. This change takes effect the next time your system starts. For more information, see Creating a dynamic system setting.
Reset this value to enable compression when debugging is complete.
Domain Name System lookups required
In some Pega Platform installations, the
value appears only as a numeric Internet Protocol (IP) address. The true
ClientHostName is visible only when the application server is enabled to
perform Domain Name System lookups:
- For Tomcat-based systems, set the parameter
server.xmlfile) to "true" to allow DNS lookups.
- For Oracle Weblogic, add the parameter
config.xmlfile to allow DNS lookups.
Duplicate trace error
If the node hosting your trace session fails and you attempt to trace the same service again, you might encounter a duplicate trace error. Clear stale trace sessions using Admin Studio.
