hi all,

i've made an application , which serves more than 35 cuncurrent users at a time,
now wht i m doing on the page where the data is being submitted is :

run a loop which iterates through all the submitted data of $_REQUEST
and i make a query and update that to the Access Database, on every rep of that loop.

the loop iterates five times, now ..............

if 35 users submit at the same time, 
the loop will run five time each for each of the user i.e 35 x 5.

here my application crashes and every person ( user ) is redirected to the login page, 
and all the data is lost in-between the application run.

note : no error is raised by the script or server.

any comments, on how can i do resource sharing or connection sharing etc. to avoid 
that????


regards
raheel

An alternative could be switching to a SQL server ( MS SQL ) or the free
MySQL (which performes on unix-like systems better ).
I avoid using Access databases because of problems like you described.

hi again
well Yes, i m gonna do that, but the question remains there wht  if i do resource 
sharing means that if i want to block the connection sharing like what is being done 
in Java or other applications 
called connection pooling,
so how can it be done in PHP, just like java uses sleep() function , so is there any 
technique present in PHP????

I’m kind of new to PHP, and I need help trying to figure out why my HTTP authentication scrip isn’t working correctly.   All scripts including the db dump are included.   I am running a Linux box with Apache Apache/1.3.27 & PHP PHP/4.3.1 with PHP installed as a module. In IE when I navigate to index.php I am prompted with a login dialog box however when I enter in a username and password that I have validated are in the MySQL database I am prompted with the box again. I am never given access to the page.   Is there something I am missing, or something I should configure in my httpd.conf file to get this to work? Your help is greatly appreciated.   Regards   Tashfoo

Dear all
I had write a script like this :

$link = "page.php?day=$day&month=$month&year=$year";

when i click on the link, it should pass the parameter to "page.php" with
$month and $year variables.
It actually works fine in php4.2.1, but when i went to other office which
got php5.0 above installed, using the same script, but it won't pass any
parameters to page.php! How come?

I heard there is something to set in the php5.0's php.ini before i can do
so, is that right?

Please could anyone give me a hand on this?

Thx alot

Jack

Or access you variables via $_GET.

$varname = $_GET['varname'];

I've read up on this 'wait_timeout' and 'interactive_timeout' and brought it
right down to 300 seconds.  While I now have less big sleep timeouts (may be
coincidence) there are still a handful that currently up to around 700, and
increasing!  Is there any way possible of establishing what these users have
done on the webpage (even a URL would be handy, as I could then at least see
what course of action they selected)?  Somehow I guess it isn't possible?!

Following this, the mysqld process still regularly hogged the CPU, and was
up at 100% most of the time.  I then set the following in the ini file
set-variable=key_buffer=512K
set-variable=max_allowed_packet=1M
set-variable=table_cache=256
set-variable=sort_buffer=100k
set-variable=read_buffer_size=100k
set-variable=record_buffer=1M
set-variable=myisam_sort_buffer_size=64M
set-variable=thread_cache=8
... which was suggested in the documentation for lots of connections, but
again no noticeable difference.

I stopped and restarted the service a few times, and the CPU usage always
went straight back up to 100% by the time say a dozen users were connecting
again.  I am now going to try the query_cache_size setting you mentioned,
and will see if that helps the situation.

I have installed MySQL 4014 on the machine which is currently running the
website, and intend to copy the database from the other machine over to it
once this problem goes away :-)  I'm with you in that I don't think it's
going to have much bearing on things though.

With many thanks again for your time and help
Gary

Then you might want to open a socket with php, and I think php
is able to do this. Check out http://www.php.net/socket, but
also socket_bind in particular.

require ("d:/iis/www3/lib/common/auth.inc"); 

require ("/lib/common/auth.inc"); I need.

 

When I want to include some file, I must key in the absolute directory. So I change 
include_path line to "include_path = d:/iis/www3/" in "php.ini" file. But it doesn't 
work.Please tell me the reason.

 

When some clients visited my web site, I want to keep their E_mail address in my 
database. Please tell where I can get this kind of skills and materials. 

 

thank you,

 

Michael
