Re: STRTCPSVR not starting up an http server instance in startup program.

Hi Rob,

Very in depth.

What program is it that does a RTVSYSVAL SYSVAL(QCTLSBSD) and starts that
subsystem?

DSPSYSVAL SYSVAL(QSTRUPPGM) reveals that MXSTARTUP is the startup program.
It retrieves sys val above as per below.

<mxstartup snip>
QSYS/RTVSYSVAL SYSVAL(QCTLSBSD) RTNVAR(&CTLSBSD)
IF COND((&CTLSBSD *NE 'QCTL QSYS ') *AND (&CTLSBSD *NE-
'QCTL QGPL ')) THEN(GOTO CMDLBL(DONE))
QSYS/STRSBS SBSD(QSYS/QCTL)
MONMSG MSGID(CPF0000)
QSYS/STRSBS SBSD(QCMN)
MONMSG MSGID(CPF0000)
STRTCP
MONMSG MSGID(CPF0000)
DLYJOB DLY(15)
QSYS/STRSBS SBSD(MIMIXQGPL/MIMIXSBS)
</mxstartup snip>

The only other sysval it retrieves is QSTRPRTWTR.

The only other pgm it calls is mxstartup2 which calls no
other pgms, rtv's no other sys vals and submits no other jobs.

I'm in wait and see mode.

Thanks,

John B

What program retrieves the IPL attribute set by CHGIPLA STRTCP(*NO) and
decides whether or not to start TCP/IP? Which program actually does
STRTCP? Would that be a particular autostart job entry in QSYSWRK?

What program retrieves the IPL attribute set by CHGIPLA STRRSTD(*YES) and
processes that accordingly? Would that be the program specified in the
autostart job entry for both QBASE and QCTL - QSTRUPJD which does
QSYS/CALL QSYS/QWDAJPGM? And QWDAJPGM is set to Allow RTVCLSRC = *NO. Is
this the program which does a RTVSYSVAL SYSVAL(QSTRUPPGM) and calls that?

Knowing the timing of all of this may help your customized QSTRUP program
ensure that it doesn't start an http server instance before it's time.

If you perform a RTVCLSRC on an uncustomized QSTRUP you will not see it
starting any TCP/IP. At least on currently supported versions of the OS.
