Question & Answer
Question
I need help displaying status information for a ctrace on TCP/IP.
Answer
To display information about the status of the component trace, issue the following command:
DISPLAY TRACE,COMP=component_name,SUB=(procedure_jobname)
See this URL for more information about the component name:
This command displays information about the status of the component trace for one procedure. To display information about the status of the component trace for all active procedures, issue the following command:
DISPLAY TRACE,COMP=component_name,SUBLEVEL,N=8
For the TCP/IP CTRACE components, do not be misled by the line in the middle of the display showing the MODE is OFF. This part of the display always says the MODE is OFF because TCP/IP uses the subtrace for all tracing. The subtrace for TCPCS2 indicates the actual state of the trace.
Use the DISPLAY command to check the external writer status. Include a sublevel.
D TRACE,COMP=SYSTCPDA,SUB=(TCPCS2)
IEE843I 11.33.06 TRACE DISPLAY 099
SYSTEM STATUS INFORMATION
ST=(ON,0064K,00064K) AS=ON BR=OFF EX=ON MT=(ON,064K)

SYSTCPDA
MODE BUFFER HEAD SUBS
=====================
OFF HEAD 2
NO HEAD OPTIONS
SUBTRACE MODE BUFFER HEAD SUBS
--------------------------------------------------------------
TCPCS2 ON 0016M
ASIDS *NONE*
JOBNAMES *NONE*
OPTIONS MINIMUM
WRITER PTTCP
In the example shown above, the trace is active (MODE is ON) with an internal buffer size of 16 M, tracing all ASIDs and all JOBNAMES, using MINIMUM options, and using the external writer PTTCP. Another version of the DISPLAY TRACE command D TRACE,COMP=component_name,SUBLEVEL,N=8 shows all subtraces for the component.
Modifying the trace buffer size: To modify the amount of trace buffer in use for the SYSTCPIP, SYSTCPDA, SYSTCPIS and SYSTCPOT traces use the following command:
TRACE CT,nnnnM,COMP=component_name,SUB=(procedure_jobname)
where nnnnM is the new buffer size in mega bytes. The buffer size is subject to the minimum and maximum buffer size established for each component.
