The typical response was very fast (on miliseconds).
The access to the database is is part of the connection string on the
program.
Apache authenticate the user access to the directories that containts
the perl programs, using the httpd.conf and the htgroup and
htpasswd file.
ex.
<Directory /usr/local/apache2/cgi-bin/indocadmin>
AllowOverride None
AuthName "INDOC"
AuthType Basic
AuthUserFile /usr/local/apache2/conf/.htpasswd
AuthGroupFile /usr/local/apache2/conf/.htgroup
<LIMIT GET POST PUT>
require group INDOCSEC
order deny,allow
deny from all
satisfy any
</limit>
</directory>
initialy i get the log message:
POST HTTP/1.1 401
then is enter user id and password and click enter.
then i get a delay of 40 seconds or more and the log message:
POST HTTP/1.1 200
indicating OK
No one has changed the Sybase database, i have the only unix
workstation, that can telnet to the Database Server. We are using an
intranet classified network. The Apache, Sybase and the programs are
all in the same server.
Hello Oscar,
I don't have much idea why you are seeing such a big difference in
response time.
But I do have some further questions that may be useful to you or to
someone else on the mailing list that may have a clue what is happening.
First of all, logic would seem to indicate that if we are seeing this
big of change in the result, then something must have changed in the
scenario.
A suggested task would be to try to figure out what is different.
Could there be any new programs running on your system that might be
causing contention of some sort?
If you are using an intranet classified network, does this mean that you
are using network protocols other than TCP/IP?
Since you are using perl scripts, are you also using mod_perl?
We would like to discern which part of the request/response round trip
is using up the extra time.
Is the time lost in the Apache httpd server, mod_perl, the perl script
or in the access to the database?
Would it be possible to run your perl scripts directly from a shell and
compare the response time to the overall response time through the httpd
server?
Thanks,
Mike
