Well if he wants it in an RPG program then simply use HTTPAPI - really easy to use.

Yes http call definitely more accurately.

A little curl via QSHEXEC or QSHBASH will solve that for you.

Same result is outfile data to process from QTEMP/STDOUTQSH.

I don't usually use or recommend the DB2 http stuff.

Wouldn't it be more reliable to actually run an HTTP request against the port? All NetStat is going to tell you is that something is listening. Or even Telnet.

I haven't followed this thread, but one option to check for an active service is simply to use the DB2 services SQL to do a NETSTAT port check via SQL:

Ex SQL to check for port 80:
SELECT * FROM QSYS2.NETSTAT_INFO WHERE CONNECTION_TYPE='IPV4' and LOCAL_PORT=80

This is packaged in a CL command called QSHPORTCHK as part of my
QShell on i Tools (QSHONI) https://github.com/richardschoen/QshOni

And here's a sample where I'm using QSHPORTCHK to check for a Postgres Server and Gitbucket running on an IBMi system.

If port check fails, you could then run whatever commands you need. And if they are QSH/PASE commands, you can use the QSHEXEC or QSHBASH commands to fire them up from the green screen or job scheduler.

Also with this example that was given in a prior post:
QSH CMD('/QIBM/ProdData/OS/WebServices/bin/listWebServicesServers.sh')

Can instead be run like this:
QSHONI/QSHEXEC CMDLINE('/QIBM/ProdData/OS/WebServices/bin/listWebServicesServers.sh')

When the command completes, simply read outfile QTEMP/STDOUTQSH to process the results from CL or RPG.

Hope this helps.
