SM7 Web Tier Installation

[Falcon]

Hi All,

Has anyone successfully run through the Web Tier component of the SM7 Installation?

I'm trying to get a hold of the SAM-M0V-PJ12.zip file containing the following files but I'm not sure who to contact:
- workers.properties (6KB)
- mod_jk.conf (4KB)
- mod_jk.dll (136KB)

Anyone have any ideas or actually have the file that they can attach to this thread?

Cheers

[benvargas]

I dug this out of an old knowledge article applicable to SC6.x but it worked for me with some tweaking... I also contacted HP support to request it per the installation instructions however, they haven't provided it yet after a week and a half of waiting - I don't think Support has access to the file yet.

[Falcon]

Thanks mogrefy, much appreciated.

[Falcon]

Has anyone successfully got the SM7 Web Tier up and running following the Installation Guide provided by HP? I'm pretty sure I have followed it exactly but still can't get it to work.

All I get when I try to access //localhost:8080/webtier-7.00/ is:

HTTP Status 404 - /webtier-7.00/

    type Status report
  message /webtier-7.00/
  description The requested resource (/webtier-7.00/) is not  available.

If you have got it up and running, may I ask what versions of Tomcat, Apache/IIS did you use to get them to work together?

Was there anything that you had to do that was not described in the installation guide that is crucial to get the installation to work?

Any advice or assistance would be greatly appreciated.

Yes, I have successfully setup the SM7 web tier with Apache Tomcat and HTTP Server. I have attached a PDF containing some of my installation notes (and links) based my installation and experience following the SM7.0 documentation.

Please do not re-distribute without crediting me and do not remove the header information, thank you.

Hope this helps!

Hi Ben,

Thanks very much for posting your install notes, I'll start afresh and give it another go. Much appreciated, and rest assured that I will respect your wishes in regards to re-distribution.

Cheers.

Wow, these instructions were perfect. If only the HP docs were so well written.

Nicely done.

[benvargas]

Great, I'm glad that you guys are finding it useful!

I used to work for Peregrine / HP ... but in Support rather than Documentation

Hi there,

I've been following mogrefy's installation instructions but have come across an error message at Step 08-B.

When I try to access http://localhost:8085/webtier-7.00/index.do I get the following error message:

An error has occurred while processing a request for: /webtier-7.00/index.do

Please contact your Administrator or see server logs for more details

Error: javax.xml.soap.SOAPException: Message send failed - connection to host http://localhost:13080/SM/ui refused. Your server session may have been terminated or timed out. You may need to go to the login page and log in once again.

View/Hide Error Detail

I can't seem to figure out what the problem is, is it a permissions issue on the server? I noticed that it is referencing the .../SM/ui folder. I've tried to do a string search to find which file is referencing this link but haven't had any luck.

Before trying to load this page I can successfully bring up the Tomcat homepage at //localhost:8085/ and the Apache homepage at //localhost/.

This means that you are failing to connect to the Service Manager app server. Is the app server running on the same machine and on port 13080? If it's on a different machine or port, you need to configure that in web.xml of the web client.

[Falcon]

Thanks glg, I'll look into it.

Thanks I just used these instructions to install (well I have not done step 9 and forward yet but sofar it works). I have a few suggestions for updates though.

Add 6D: Start Tomcat to get the wbetier depolyed

Maybe add a note on which file to edit to change the default port for Tomcat. For now I have just used 8080 since I did not know where to edit. (I know I can just read the tomcat documentation or google for it).

Hi,

I am trying to install web tier for SM7 as per the PDF document provided by Mogrefy.

Up to 6 steps I have successfully installed and configured the same. But When I try to access //localhost:8080/webtier-7.00/index.do is: I am getting following error

Code:
HTTP Status 404 - /webtier-7.00/

type Status report
message /webtier-7.00/
description The requested resource (/webtier-7.00/) is not available.


waitinf for your reply.

Thanks

Have you checked that the sc.war has been extracted and the folder is created ?

[ripple]

Hi,

War file is placed and extracted also and according to Document I have modified the WEB.XML file.

Thanks,
Ripple

[tommy]

Have you copied the endorsed files?

[ripple]

Hi,

Yes I have copied the files also.

Thanks,
Ripple

Hello ripple,

Did you make change in worker.properties and mod_jk.conf ?
This file from SAM_MOV_PJ12.zip are for SC6... All URI need to be updated...
Alias, jkmount and rights also.
nb : if you didn't do it before apache installation, you need to "repair" Apache (standard option) after this change. (mod_jk.conf)

Regards,

Merlin

Thats not relevant at the stage where ripple is currently. You talk about step 9. Ripple's installation fails in step 8

[ripple]

Hi,

You are right. I am stuck up at step 8 only.
Is there any other way I can cross verify it.

Thanks,
Ripple

[ripple]

Hi,

I have successfully completed the step 8 also but when I am modifying the HTTPD.CONF file as mentioned in the step9

Include "c:\www\apache2.0\apache2\conf\mod_jk.conf"

after restating services, my apache2.0 services are not starting.

but when I am removing the same comments then apache services are running fine.

Thanks,
Ripple

[njoylif]

I was asking for those files and I’m afraid we don’t provide it. You need to get the jars that are in the zip from the Jakarta website.
Please let me know is there is something else that I can help.

fyi

[njoylif]

probably a noobie ?, but, I don't have an index.do in my webtier-7.00 directory. Is this auto generated or did I screw something up?
Thanks

[njoylif]

must have been something I did. started process over and its working now.
I was using apache 2.2 instead of 2.0 and had a different flavor of java (included the jdk) in a different location...
FOLLOW DIRECTIONS as closely as possible.

Great directions Mogrefy!!!!

Hi,
I think you have this error in windows error log (applications):

Hi,

the whole webtier works fine in my configuration. But there is one thing not clear to me:

If I just install Tomcat 5.5 I can already deploy the webtier and use it.

Why do I need in addition the Apache2.0 Webserver? The only difference I noticed is that I can now connect on port 80 and a /sm7 is good enough to connect to the webclient. Is there more?

Oliver

[tommy]

The apache webserver is as far as I can tell only required if you need the users to access ESS with an url without specifying the portnumber (if tomcat is not running on default port 80). If you link the ess from a company portal apache is not necesary in my opinion.

[oliver]

Hi Tommy,
thanks for your response. Then I think we will not use the Apache2 server.

I see in the Tomcat startup-log that it cannot find the native DLLs.
Do you know where I can find these DLLs and how to integrate them?

[gmorales]

HI I have the same problem, but I fixed using this versions of jakarta-tomcat-5.0.28. and java jdk-1_5_0_12-windows-i586-p.exe, It allways works on this versions

Well, I think you're missing the point here.
Httpd daemon, in this case, functions as a proxy to the webapp server (or, rather, servers). In real world scenarios a single tomcat instance is simply nor enough, hence the proxy.

Tomcat is extremely easy to setup to listen on port 80, just add one line in conf\server.xml (duplicate the line with 8080 definition).

benvargas, a quick question, if I may.
From your experience in the support, is there a particular reason for Peregrine/HP sticking with mod_jk instead of using mod_ajp? I find the latter much easiet to setup and the supplied balancer_manager app is great.

[benvargas]

I definitely can't speak for HP or their Support since I don't work for them anymore, but I can give my opinion...

I don't believe there is an actual preference or recommended connector for Apache Tomcat to Apache httpd; there used to be a support article that had the mod_jk files (linked above) configured, and referenced by the SM7 installation guide. However, when I requested it HP Dev/Support said that is was a mistake to have it in the document and was not to be provided by HP Support.

This stance doesn't surprise me because when I was with Support, the policy was often that we could walk through deployment on an Application Server such as Tomcat, but it was up to the customer's Web Administrators and/or Tomcat Administrators to actually configure the connector to allow the two applications to talk (or balance).

So, I think that they're getting away from providing and endorsing any connector methods and leaving that up the the Web/Tomcat Administrators. A lot of times the first thing support will have you do when troubleshooting a problem is connect directly to tomcat on 8080 and replicate the issue - this assists them in cutting out the connector and httpd as part of the puzzle.

From your post, it sounds as if you're successful with mod_ajp and the SC/SM web client? If so, it would be great if you posted some example configuration files for those that haven't gone that route yet.

Hi, thanks for the reply.

Well, this is much, much simpler than mod_jk.

1. install apache httpd 2.2.x (the newest the better in this case)
2. open httpd.conf in text editor
3. enable: mod_proxy, mod_proxy_ajp, mod_proxy_balancer
(remove # in the proper LoadModule config lines)
4. put following in the last lines of httpd config:

<IfModule mod_proxy.c>
 ProxyRequests Off

<Proxy balancer://smclust>
 BalancerMember ajp://sm01-centrala:8009 route=tomcatA
 BalancerMember ajp://sm01-centrala:8011 route=tomcatB
 BalancerMember ajp://sm01-centrala:8013 route=tomcatC
</Proxy>
<Location /sm7>
 ProxyPass balancer://smclust/sm7 stickysession=JSESSIONID|jsessionid
</Location>

#helpserver proxy
ProxyPass /smhelp http://smhelpserver.hostname:8083

#balancer-manager app
<Location /balancer-manager>
 SetHandler balancer-manager
 Order Deny,Allow
 Deny from all
 #put your host address below for gaining access to this app
 Allow from localhost 
</Location>
</IfModule>

5. define routes in all tomcat conf\server.xml's
<Engine name="Standalone" defaultHost="localhost" jvmRoute="tomcatA">

6. deploy SM7 webtier app to all tomcat instances
(make sure the tomcat's webapp url matches the one defined in httpd.conf - in this case "sm7")

7. start/restart httpd, check balancer status under http://<http webserver>/balancer-manager
Try accessing http://<http webserver>/sm7
while looking at the balancer app, you should see some new stats.

8. You're (hopefully) done!

mod_proxy_balancer documentation (extremely helpful): http://httpd.apache.org/docs/2.2/mod..._balancer.html

HTH.

i have done until step 9. when i tried to access webtier client through Apache HTTP server(through tomcat server is successful), i got error HTTP Error 404 - File or directory not found.
My Apache server is not able to start. The start/stop buttons are disabled.

It sounds like you missed something when configuring the mod_jk connector, Apache2 is looking for sm "stuff" within the htdocs directory rather than "linking" to Tomcat. I'd advise that you focus on the mod_jk part of the integration and make sure you didn't miss any of the modifications or lines within the modifications.

i have attached mod_jk.conf. couldn't find anything missing.
my apache server port is 8080. I need to sort it out asap for the demo

Can i know is the web access for ESS? I need to access ESS but wonder how to install and configure it.


kindly help. Many thanks.

There is a bit more to it that just the mod_jk.conf file; did you also double check your workers.properties configuration as well as httpd.conf configuration? Many people have had success (within the company I work for and here on the forums) if you follow the PDF posted above.

Alternatively, you could just use Apache Tomcat for your demo, especially if you're already attempting to run Apache on port 8080 (which is slightly odd because that is the default Apache Tomcat port, Apache HTTP would be on port 80 - you weren't really clear by "apache" which application you were referring to). You can access the client just fine without having to setup the Apache HTTP to Apache Tomcat connector, that is an additional step.

Did you use the PDF file posted above for your configuration? Sorry, I don't have the bandwidth right now to be of much more assistance - paid clients work to do =)

hi Ben,
Thanks for your response. I did check on workers.properties and httpd.conf. I followed the pdf above exactly. The reason i use port 8080 is because i have IIS installed on same machine using port 80. I need to access ESS, supposed it's to run with apache http?

[low]

Hi all,

I managed to run webclient using apache server after i reinstalled apache server using port 80.

Thanks alot!!!

We have SM7 running on solaris 10 . The HP documentation talks about setting up the web tier only on windows . Can anyone help with setting it up for Apache 2 on solaris. TIA - Rajat

Please shoot with a specific question instead and I'll try to help.

Done this on Solaris 9&10 and it was fairly straight forward.
Just make sure to use precompiled packages either from SUN or via pkg-get util.

[hmontoya]

I'm trying to set up a load balancing and cluster environment for apache-tomcat to use with sm7 web module.

I installed two instances of apache-tomcat, mod_jk and I edited the httpd.conf and worker.properties files and configure that to work as a cluster and load balancer .

I executed an evaluation on jsp to verify the balancer and cluster and both worked fine.

but when I try to logon on Service Manager portal via apache (http://localhost:80/sm7) only appears the header of SM web portal but when I click on refresh button innmediatly appears the user, password and language fields and after a couple seconds the web client shows: http://localhost/sm7/goodbye.jsp?lan...sessionTimeout and appears the label and link disconnection sucessfully and connecting again.

I'm stucked and any help is welcome.
