WL Apache plugin BUG: ConnectTimeoutSecs does not work.

Question

We have a Servlet that calls an Entity Bean that performs a process that
takes about 15 seconds to return. I noticed that the Weblogic to Apache
bridge times out in 10 seconds, calling the servlet about 4 times. I
then proceeded to change the ConnectTimeoutSecs to 60 seconds and then
changed the ConnectRetrySecs to 60 seconds also to prevent multiple
retries. Now when I run the servlet, I get the following response after
waiting about 10 seconds:
Failure of WebLogic APACHE bridge:
Cannot connect to WebLogic: timed out after 60 seconds
Build date/time: Jun 5 2000 20:55:01
It appears that the plugin is ignoring the new value except for the
error message. I have included my setup below.
Excerpt from httpd.conf:
<IfModule mod_weblogic.c>
Include conf/weblogic.conf
</IfModule>
Entire weblogic.conf:
WebLogicHost devapp1
WebLogicPort 7001
#PathTrim weblogic
#PathPrepend
#StatPath false
#ErrorPage
ConnectTimeoutSecs 60
ConnectRetrySecs 60
<Location /servlets>
SetHandler weblogic-handler
</Location>
Weblogic App Server:
OS: RedHat 6.2 (2.2.14-5.0)
JDK: Sun's Java 2 SDK for Linux (1.2.2)
Weblogic: 5.1 sp3
Apache Web Server:
OS: Redhat 6.2 (2.2.14-5.0)
Apache: apache-1.3.9

Answer 1

ConnectTimeoutSecs is between the browser and plugin. So the plugin will keep
trying
to connect to WebLogic till ConnectTimeoutSecs and then return a timeout error
page
back to the browser.
HungServerRecoverSecs is for timing out the requests between plugin and
WebLogic.
This was impletemented to take care of Hung or non responsive servers.
If the servlets do not respond within HungServerRecoverSecs, the plugin will
declare
that server as "hung" and failover to the secondary, if Idempotent=ON
(default). If
Idempotent (a plugin parameter) is turned OFF, then plugin will return request
timeout
error page back to the browser.

What exactly is the difference between ConnectTimeoutSecs and
HungServerRecoverSecs?

Remove "=".
Just do add this line:
DebugConfigInfo ONConnectTimeoutSecs: '60'ConnectRetrySecs: '2'
HungServerRecoverSecs: '10'

When I inserted 'DebugConfigInfo=ON' into my weblogic.conf, Apache said
this:
Syntax error on line 13 of /etc/httpd/conf/weblogic.conf:
Invalid command 'DebugConfigInfo=ON', perhaps mis-spelled or
defined by a module not included in the server configuration
I am using mod_wl.so from sp3. I did give all my version info earlier,
but here it is again:
