Обсуждение: DBD::Pg is suddenly acting up!
Just today I started to receive the below
errors. Now that I've stopped and restarted
mod_perl server and postmaster
none the scripts which rely on DBI work
anymore. Can someone help me??
At first the error was intermittent
but now it looks like permanent.
I use Apache::DBI and makes persistent
connection but that is not even working.
I tested psql manually and everything
seems to be fine.
I am using mod_perl 1.25 and all was
well until this morning. The server
was brought online only a copule of
days ago but the scripts and configuration
have been working ok for over a month
now

The problem mysteriously disappeared after I reinstalled postgres under /usr/local/pgsql instead of /home/newsreader/pgsql is that weird or what On Wed, Feb 21, 2001 at 04:45:09PM -0500, newsreader@mediaone.net wrote: > Just today I started to receive the below > errors.

No.. it was originally installed with /home
on this brand spanking new box and /usr/local
directory does not exist before
The thing is that my two web servers are run
under two other user ids and only under
web server environment these scripts were dying.
I cooked up a test script which runs fine
from the command line run under the id of
the owner of pgsql. The same test
script failed under web servers. It
was working before... but I was messing around
with permission on the home directories and
somewhere along the line things got too restrict
Only later in the day when I check logs I
realise that things were wrong.
BTW I wish later distributions will come
with better start and stop scripts.
pg_ctl is completely not working for me. I do
$ pg_ctl -o "-F -S 2048" start
and it keeps telling me I'm not doing it right.

Indeed, you are not. Try
pg_ctl start -o "-F -S 2048"
regards, tom lane
Thank you. Look what I get..
------------------
$ pg_ctl start -o "-F -S 2048"
postmaster successfully started up.
$ usage: /home/newsreader/pgsql/bin/postmaster [options]
-B nbufs set number of shared buffers
-D datadir set data directory
-S silent mode (disassociate from tty)
-a system use this authentication system
-b backend use a specific backend server executable
-d [1-5] set debugging level
-i listen on TCP/IP sockets as well as Unix domain socket
-N nprocs set max number of backends (1..1024, default 32)
-n don't reinitialize shared memory after abnormal exit
-o option pass 'option' to each backend servers
-p port specify port for postmaster to listen on
-s send SIGSTOP to all backend servers if one dies
---------------------
I've found that
pg_ctl -o "-o -F -S 2048" start
works as well as
pg_ctl start -o "-o -F -S 2048"
------
If you read man page of pg_ctl you will see that
it is telling you wrong

BTW what is show below was done on a different machine where postgres is installed in a user directory.. Just to rule out confusion I had earlier I deleted bin lib include in the user home directory and reinstall it under /usr/local/pgsql and the problem still remains namely I have to supply extra -o to make it work.
