Chapter 10. Troubleshooting your CGI programs

You can use the Workwith Active Jobs (WRKACT JOB) command to check on the

status of server jobs, as follows:

WRKACTJOB SBS(QHTTPSVR) JOB(server_instance)

When the server is not processing a request, the Work withActive Jobs display

might be similar to Figure 1:

To find out if server jobs have ended abnormally, check the spooled files that

contain the job logs (QPJOBLOG) for the user profile QTMHHTTP.

The symptoms that are described in this section would be seen running a request

to the AS/400 server at a browser.

Symptom

Connection abandoned, dropped, or no data sent.

Note: Different browser issues different messages when no data is returned to the

browser. Abandoned, droppedor no data will be displayed at the browser.

Cause: The system has incorrectly formatted a CGI program that writes data to

standard output. The data that is written to stdout may have one of the following

problems:

vNo data written to stdout

vNo “Content-type”,“Location”,or“Status”line
