Re: Apache HTTP Server and Weblogic Plug-in for Apache (Apache Users)

Hi all,

thanks for your attention and pacience. My Apache nversion can be seen below (sorry for forgeting to say):

[apache@vm-apache conf]$ apachectl -v

Server version: Apache/2.2.15 (Unix)

Server built: Feb 13 2012 18:23:03

I had some progress... i disabled the firewall (SELinux) on the Apache server. Before, i had just disabled the firewall from the Weblogic Server. Now, when i access the apache server, it redirects (sometimes, actually) the request to my Weblogic Cluster. Let's say that 50% of the time it works and the other 50% i get the error informed previously.

I am using the apache user and the ulimit of this user is:

[apache@vm-apache conf]$ ulimit -a

core file size (blocks, -c) 0

data seg size (kbytes, -d) unlimited

scheduling priority (-e) 0

file size (blocks, -f) unlimited

pending signals (-i) 15915

max locked memory (kbytes, -l) 64

max memory size (kbytes, -m) unlimited

open files (-n) 1024

pipe size (512 bytes, -p) 8

POSIX message queues (bytes, -q) 819200

real-time priority (-r) 0

stack size (kbytes, -s) 8192

cpu time (seconds, -t) unlimited

max user processes (-u) 1024

virtual memory (kbytes, -v) unlimited

file locks (-x) unlimited

From the Apache server (192.168.0.149), when i execute the "culr" command, i get the following message:

[apache@vm-apache conf]$ curl http://192.168.0.123:7006/benefits

<html><head><title>302 Moved Temporarily</title></head>

<p>This document you requested has moved temporarily.</p>

<p>It's now at <a href="" href="http://192.168.0.123:7006/benefits/">http://192.168.0.123:7006/benefits/">http://192.168.0.123:7006/benefits/</a>.</p>

</body></html>

The message above represents a OK situation or a problematic one?

Below you can see the last few lines of my Error Log and Access Log:

Is there any additional or recommended configuration for this solution to work properly?

Thanks again for the attention and pacience.

If you can provide your mpm and it's settings and httpd version, I'd say you are using 2.2.x because of the module file you use(mod_wl.so instead of mod_wl_24.so), but just to make sure. (on a side note, Oracle recommends WLSRequest on instead of SetHandler, you should use it too).

Also make sure backend has no issues connecting manually: "curl http://192.168.0.123:7006/benefits"

Also how are you starting up httpd, how and which user do you use? have you checked ulimit values when doing so?

Hi all,

I am trying to configure a test env with an Apache HTTP Server and an Oracle Weblogic 12c Cluster. The configuration is:

Apache HTTP Server: 192.168.0.149
Weblogic Cluster......: 192.168.0.129 (2 Clustered Managed Servers in the same server for testing purposes).

The configuration of my httpd.conf file, regarding the plug-in configurations can be seen below:

[...]
Listen 8080
[...]
LoadModule weblogic_module modules/mod_wl.so
[...]
<IfModule mod_weblogic.c>
WeblogicHost 192.168.0.123
WeblogicPort 7005
</IfModule>

<Location /benefits>
SetHandler weblogic-handler
WebLogicCluster 192.168.0.123:7005,192.168.0.123:7006
WLSocketTimeoutSecs 20
</Location>

When i try to acess my app (benefits) using the address http://192.168.0.149:8080/benefits, i get the following error:

No backend server available for connection: timed out after 10 seconds or idempotent set to OFF or method not idempotent.

At the error_log, the error message is the following:

[Tue Dec 16 23:37:14 2014] [error] [client 192.168.0.118] <849214187838263> weblogic: *******Exception type [NO_RESOURCES] (apr_socket_connect call failed with error=13, host=192.168.0.123, port=7006 ) raised at line 1682 of URL.cpp

13 = EACCES

This would appear to be the cause (from Linux man pages):

"connection request failed because of a local firewall rule"

[Tue Dec 16 23:37:16 2014] [error] [client 192.168.0.118] weblogic: Trying GET /benefits at backend host '192.168.0.123/7005; got exception 'NO_RESOURCES: [os error=13, line 1682 of URL.cpp]: apr_socket_connect call failed with error=13

What am i doing wrong? Thanks for the attention and pacience.
