Troubleshooting Example
ptrace from tr1
starts the PTrace trace formatter on the trace located in the file TR1 and displays the
following:
You should next set up the select mask and the filters for the trace. Since you already
know that the incoming connect TPDU was refused within TSP, you need be interested
only in the Layer 4 activity. Use the following PTrace commands to select all the
appropriate trace records:
select l4; filter l4sm; statetables $system.zosits.os4smt;
filter l4services
record all
The first trace record found is displayed as follows:
Record #30 indicates that the T-CONNECT attach has enabled the Transport Layer to
accept an incoming CR-TPDU.
Records #32 and #38 indicate that the state machine has enabled the Network Layer to
establish a connection.
Record #66 shows the incoming CR-TPDU. The attributes include the TSAP IDs
(TSELs), TPDU size, and other parameters.
Trace of: \MARS.$TSP2, Type (55,4).
