Subject: [users@httpd] Apache 1.3.41 on SunSolaris 10: htppd -F returns setsid
 error if started by a controlprocess

Hi folks

I currently have a problem with Apache 1.3.41 running on SunSolaris 10.
We have to use=20
the version 1.3.41 because of a dependency to a third party product
which doesn't support=20
Apache 2.0 and higher.


What I want to do:
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
I want to start/stop the apache (httpd) by a program called 'sapcontrol'
which is part of a SAP Installation.


Codeline, how httpd is being called:
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
httpd -F -f /usr/sap/HAP/SYS/global/pa/conf/httpd.conf


My problem:
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
Although 'sapcontrol' calls the httpd with the option "-F", which causes
the mother process (sapcontrol) to=20
not fork&detach, the httpd process doesn't start.  Instead I find in the
logfile following error message:
setsid: Not owner
wspa.sapHAP_DXPPW00: setsid failed
setsid() failed probably because you aren't running under a process
management tool like daemontools
(wspa.sapHAP_DXPPW00 is a link pointing to httpd)


What I already tried:
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
- start httpd with the option "-X" (debug mode) but without "-F":
  httpd was able to be started and stopped by sapcontrol and was running
properly; but in the debug mode it doesen't fork
  (but we need the fork feature)
- httpd of Apache 2.2.9 with the command line option "-DNO_DETACH"
behaves exactly how I want it to: does not=20
  detach and forks itself and could be started and stopped by sapcontrol
- the option "-DNO_DETACH" has no affect on httpd of Apache 1.3.41.
httpd started but forked of it's mother process
  (sapcontrol) what I don't want
- the option "-DFOREGROUND" in Apache 1.3.41: the same affect as the
option "-DNO_DETACH"
- the option "-F" combined with the option "-DNO_DETACH" in Apache
1.3.41: the same error message as started
  with the option "-F" only:
  setsid: Not owner
  wspa.sapHAP_DXPPW00: setsid failed
  setsid() failed probably because you aren't running under a process
management tool like daemontools
- the option "-F" combined with the option "-DFOREGROUND" in Apache
1.3.41: the same error message as started
  with the option "-F" only:
  setsid: Not owner
  wspa.sapHAP_DXPPW00: setsid failed
 =20
I was also searching the web and scanning this mailing list but I didn't
found an entry with a similar problem neither
a hint how to handle this problem.
 =20
Does anybody of you may know how to solve my problem? Thanks in advance
for your help!
Best regards and thanks for your time!
Patrik
