TCP/IP stack

If an abend occurs in the TCP/IP address space or in a user's address space, TCP/IP recovery dumps the home ASID, primary ASID, and the secondary ASID. This also contains the trace data for the SYSTCPIP, SYSTCPDA, SYSTCPIS and SYSTCPOT components.

To view the trace records for a problem where no abend has occurred, use the DUMP command. The following example illustrates a DUMP command:
Figure 1. Example of DUMP command for TCP/IP stack
DUMP COMM=(your dump title here)
R n,JOBNAME=(tcpipprocname),CONT
R n,SDATA=(NUC,CSA,LSQA,PSA,RGN,SQA,TRT),END
To generate a meaningful dump, specify (at a minimum):
  • CSA
  • LSQA
  • RGN
  • SQA
