on my laptop and I reguraly encounter connection problem for access to the main page in
graphical version; as it is indicated in the documentation acces is provided by navigating
at adress http://127.0.0.1:1154/apex, assuming appplication uses 1154 port, and browser is
configurated to don't use proxy for 127.0.0.1; but sometimes it works, sometimes it
doesn't!!! What could happend or what else to do?
THank you in advance for suggestions

Can you describe concretely what happens when "it doesn't" work? Any error
messages? Or does it just hang? Or what exactly happens?
Also, please watch your line length. In general, it is custom to stay under
80 characters. This makes it easier for people to reply to you, as they
don't have to scroll through your long lines. Of course, if there is a good
reason (such as log file messages, program examples, etc.), you can go over.

hmmm, it looks like maybe the process handling this port (1154) is crashed.
Does it occasionally happen that it works again a while after it has
crashed (... or does it need a reboot or Oracle restart to work again)?
What would be interesting to check is:
1. Find out what the process is called: do an lsof -i tcp:1154 while it
works, and not the name of the process. Does it have any log (use lsof
-p processnumber to check whether it has any files open that look like
log files). With ps lww processnumber, you can find out the parent
process' number, which you then can ps in turn.
2. When crashed, check with ps whether it is indeed gone (or just
stopped listening for some reason?). Whether the parent process is gone?
and samely if I check option 'no proxy' of
if I check option
'no proxy for 127.0.0.1, localhost' etc (in preferences)
if you somehow don't trust your browser or its settings, you can try to
telnet directly to the port:
telnet localhost 1154
and check whether you get a "connection refused" there too.

By it doesn't work I mean: connection is refused
ok
Firefox cannot establish connection with server
either
at
address http://127.0.0.1:1154 nor with address
http://localhost:1154; same problem occur with other
brrowsers
127.0.0.1 and localhost are actually the same thing...
hmmm, it looks like maybe the process handling this port
(1154) is crashed.
Does it occasionally happen that it works again a while
after it has
crashed (... or does it need a reboot or Oracle restart to
work again)?
What would be interesting to check is:
1. Find out what the process is called: do an lsof -i
tcp:1154 while it
works, and not the name of the process. log (use lsof
-p processnumber to check whether it has any files open
that look like
log files). With ps lww processnumber, you can find out the
parent
process' number, which you then can ps in turn.
2. When crashed, check with ps whether it is indeed gone
(or just
stopped listening for some reason?). Whether the parent
process is gone?
Once again connection is refused:
#telnet localhost 1158
Trying 127.0.0.1...
telnet: connect to address 127.0.0.1: Connection refused
Trying 127.0.0.1...
telnet: connect to address 127.0.0.1: Connection refused
Trying ::1...
and samely if I check option 'no proxy'
of if I check
option
'no proxy for 127.0.0.1, localhost' etc
(in
preferences)
if you somehow don't trust your browser or its settings,
you can try to

telnet localhost 1154

^
Ooops, should have been "note the name of the process"
Be sure to exclude firefox of course, if you have a connection right at
that time :-) We are interested in the process that is LISTENing on this
port, not in the clients that may be connecting to it...
Ok, for practical aspect I will use port 1158 here because I have
the same problem on two machine running under Suse10.* (one in 32b
the other in 64b); on current machine http is configurated on port
1158.
lsof -i tcp:1158 gives no answer
Weird... and you are sure that at this point in time, firefox was still
connecting?
When I'm launchig
firefox http://127.0.0.1:1158/apex
and ps -ax|grep firefox I obtain:
6505 ? S 0:00 /bin/sh /usr/bin/firefox
6510 ? Sl 0:40 /usr/lib64/firefox/firefox
6749 pts/28 S+ 0:00 grep firefox
Indeed, it's the server process that's important, not the client (which
is firefox obviously...)
I don't find any log-file at the moment
