4.14 Apache Tracing (IBM i)

Use the WRKSPLF SELECT (QTMHHTTP) command to view current spool files owned by this user.

Delete spool files that are not important so your next selection will be easier to manage.

Start the HTTP server instance with the -vv option.

STRTCPSVR SERVER (*HTTP) HTTPSVR (JSMAPACHE '-vv')

Look for completion message CPCA984 in the server job log for confirmation that the trace option you specified has been accepted.

 

User Trace option changed for job 

534123/QTMHHTTP/JSMAPACHE.

This is the manager job for HTTP Server instance JSMAPACHE.

 

Run the HTTP client program that is causing the error to occur in the HTTP instance.

End the HTTP server instance:

 

ENDTCPSVR SERVER (*HTTP) HTTPSVR (JSMAPACHE)

 

Use the WRKSPLF SELECT (QTMHHTTP) again to view the created trace spool files:

 

QZSRHTTPTR  QTMHHTTP   PRT01   QSRV534123  HLD  16

QZSRHTTPTR  QTMHHTTP   PRT01   QSRV534124  HLD  1

QZSRHTTPTR  QTMHHTTP   PRT01   QSRV534125  HLD  30

QZSRHTTPTR  QTMHHTTP   PRT01   QSRV534126  HLD  21

 

Also you can start tracing any time (without stopping and starting the instance) by using the following commands:

 

TRCTCPAPP APP(*HTTP) HTTPSVR(JSMAPACHE) TRCLVL(*VERBOSE)

 

TRCTCPAPP APP(*HTTP) SET(*OFF)
