Configuring Packet Tracing › Configure SmartTrace

Configure SmartTrace

SmartTrace is implemented in the Packet Analyzer; therefore, the Packet Analyzer must be enabled to use SmartTrace. This configuration is done when you set up your product.

Default settings are defined; however, the settings are customizable when you run the following packet traces in your region:

• Traces that are started using the PT line command against a resource or connection
• User-defined traces, unless overridden in the trace definition

The default settings are customizable through the SMARTTRACE Customizer parameter group. During Express Setup, the group is populated with discovered ports associated with DB2 Distributed Relational Database Architecture (DRDA), FTP, HTTP, and Telnet for decoding packets.

Follow these steps:

1. Enter /PARMS at the prompt.

   The Parameter Groups panel appears.

2. Select $IP SMARTTRACE from the Tuning category.

   The SMARTTRACE Customizer panel appears.

3. Complete the following fields:

   Note: For information about the Packet Analyzer parameters, see SOLVE Subsystem Interface Guide.

   Trace Limit

   Specifies the number of packets that are retained for a trace. When the limit is exceeded, the oldest packet is discarded.

   Limits: 10 through the value specified in the PAMMTTSIZE Packet Analyzer parameter in SOLVE SSI

   Trace Expiry

   Specifies the length of time that the trace is retained in memory before it is discarded.

   This value has the following format:

   hhh:mm
   

   Limits: 000:02 through the value specified in the PAMFZKPTIME Packet Analyzer parameter in SOLVE SSI

   Example: 100:10 (100 hours and 10 minutes)

   Initial Packets Traced

   Specifies the number of packets that are retained at the start of a TCP connection when you create a multiple TCP connection trace.

   Limits: 3 through the value specified in the PAMITTSIZE Packet Analyzer parameter in SOLVE SSI

   Maximum Connections Traced

   Specifies the limit on the number of TCP connection traces generated per stack when you create a multiple TCP connection trace. This limit does not include expired connection traces. When exceeded, any new TCP connections are ignored.

   Limits: 1 through the value specified in the PAMTCCCRLIM Packet Analyzer parameter in SOLVE SSI

   Press F8 (Forward).

   Page 2 of the group appears.

4. Review the ports to decode packets, and update the fields if necessary.

   Press F6 (Action).

   The details are applied.

5. Press F3 (Exit).

   The details are saved.
