Virtualize a Proxy

Hi,
I have a proxy (proxy1) which virtualizes a business service. I want to call this proxy from 5 different other message flows. In this model, what is the best transport model for my main proxy (proxy1), so that calls from other proxies to this is fast and efficient. In otherwords, what is the best model to make communication between proxies effienct. Appreciate all inputs.
Thank you

HI,
Better use local transport to communicate in between multiple proxies. Make your Proxy1 on local transport and call the same from different proxies.

Max number of agents per proxy

Is there a suggested maximum number of agents per proxy, especially a proxy co-located with the enterprise controller?
Thanks,
Tim Reidy

This would depend on usage patterns and what type of hardware the proxy controller is running.
According to some whitepapers I have you're looking at :
For only hardware management - 5000 systems per enterprise controller, 1000 systems per proxy controller
For hardware, OS, update and virtualization - 3000 systems per enterprise controller, 1000 systems per proxy controller
hardware specs are:
Sparc T3's, 16-core T3 processor, 32 GB RAM for the EC, 16 GB RAM for ProxyController
Intel, Sun Fire x4270's, 2 x Quad-core Nehalem processors, 36 GB RAM for EC, 8 GB RAM for ProxyController

ITKO LISA Virtualize

Hello:
Trying to use LISA to virtualize a Tuxedo gateway connection via WTC to a WebLogic application. In order for the service to be virtualized activities have to be recorded by LISA sitting as a proxy and listening to the conversation between Tuxedo gateway and WTC. The problem is that TDOMAIN is not a supported transport protocol for LISA. Is TDOMAIN compatible with any known transport protocol? Any idea how this can be addressed?
For further information about LISA Virtualize go to www.itko.com.
Thanks.

Hi Ransford,
Unfortunately the /TDomains protocol is an Oracle proprietary protocol and unlike any other protocol. I didn't get a chance to thoroughly investigate LISA, so I don't really know what other options you might be able to use. This is something you should probably take up with iTKO. Another possibility would be to use SALT and SOAP/HTTP instead of the Tuxedo domain gateway, although there would be more overhead in doing that as all of your Tuxedo traffic would need to be converted to/from XML by the SALT gateway. But that would give you a standard protocol (HTTP).

When attempting to use Firefox with TOR I get "Firefox is configured to use a proxy server that can't be found."even though neither is configured to use a prox

After installing TOR Browser Bundle 2.2.37-2, I get "Firefox is configured to use a proxy server that can't be found." even though neither is configured to use a proxy

Hi,
If the TOR Browser Bundle is installed you would have two versions of Firefox: the original Mozilla Firefox and the customized TOR Firefox. You can try to start the Firefox that was installed by TOR. If you have security software (antivirus, firewall etc.) installed, you can try deleting all existing instances of TOR and TOR Firefox and its related processes/files in all the different configuration areas/modules of the security software like process monitoring, sub/spawned process control, virtualization etc. in addition to the main AV/Firewall module. Instead create new fully allowed/trusted rules for TOR and TOR Firefox + its related processes. Even otherwise some security software may also ask again when TOR/TOR Firefox is started and you can try to allow/trust at that time. Please see [https://support.mozilla.org/en-US/kb/Firewalls this].

Problems with using Captivate 7 behind Proxy

Since I've upgraded to Adobe Captivate 7, I have issues while using Captivate. The program start takes very long and during working the program window sometimes freezes and then I have to wait about 15 Seconds before Captivate allows continuing my work, sometimes Captivate crashes completely. These issues are gone, when I'm disabling my network connection. I'm using Captivate inside a corporate network and behind firewall and proxy.
I tested it also with a direct internet connection, no problems. So I'm missing some adresses which are filtered by the proxy. Does a list with necessary connections for Adobe Captivate 7 exist?

It is well known that Captivate authors should ONLY work on project files that are stored and accessed from the computer's own hard drive. If you are pulling down project files from your network LAN or saving back up to the LAN using Captivate then you will have these issues. The use of virtual My Documents folders and roaming user profiles can also play havoc with Captivate's stability.
You need to set up working folders on your C drive for your Captivate projects. You'll need one for your Captivate Project Cache, one for your Captivate Publish folder, one for your Video Demo Recording Working Folder, and one for your Layouts and Themes. All should be on your own hard drive, not the LAN or (if your IT dept uses virtualization or roaming user profiles) in your My Documents folder.
Once your folders are created you can set these as the Default Locations in Preferences > General Settings > Default Locations and Preferences > Recording > Video Demo etc.
Since it appears as if you have been working over the network up to this point, you may also find that you need to kill your Preferences folder as well after setting up the local default locations. Otherwise Captivate will continue to look for the network addresses.

OHS Webtier 11.1.1.5 reverse proxy to OWA

Hi,
I am trying to create a reverse proxy to OWA (Microsoft Exchange) https but to no avail.
As you can see the code below:
<Location /owa>
ProxyPass https://10.6.145.64/owa
ProxyPassReverse https://10.6.145.64/owa
#Redirect / https://10.6.145.64/
</Location>
Redirect is working but Reverse proxy is not working. Are there any additionals code needed to make it works?
I am actually setting up SSO for OWA but I have no idea how to configure this part. :(
Please help.

"And what is it about the ip it's pointing to in the opmn log. "216.8.179.25,6700: BIND (Cannot assign requested address)"?
The IP 216.8.179.25 is probably some internal address that is found when it was unable to find the 127.0.0.1 loopback.
Could be this address is found through the virtualization platform (which usually installs some network adapters on the system) - if you are using virtualization, otherwise
you have to check with you network administrators, and see if they can make something the IP you were getting.
"But i am not sure as to why / how this has happenned."
We had the same problems (were using DHCP) - with 11.1.1.2 no problems. With a patch to 11.1.1.5 it broke down - I think it is a bug in OPMN (the 11.1.1.5 version).
But to be sure it is a bug, you better check with Oracle Support, maybe they can shed a light on this. There are no known issues mentioned in the 11.1.1.5 release notes

Squid proxy server (redhat) latency issues?

I need to deploy a proxy server on a network servicing about 200 machines.
If I virtualize redhat Linux to use squid, will the latency be too much? Bear in mind that the underlying OS and hardware (server 2008 on RAID-5 and 2GB of RAM) must also act as a WDS server. If it weren't for the necessity of WDS I would make
the whole machine a RHL box.
My boss thinks that there will be too much latency... I on the other hand don't have the experience to know or the time to build a prototype for testing it.

I would doubt that the latency will be an issue. Almost every kind of workload is being virtualized these days. Hypervisors in general, and Hyper-V in particular, offer synthetic devices such as NICs and storage controllers along with custom device
devices for those synthetic devices specifically so that performance and latency can get pretty close to what you would have with physical devices. Virtual appliances for various network functions such as proxies, firewall, and load balancers, have been
created specifically to run in virtual environments, and they are achieving the necessary performance and latency. I'm sure there might be specific situations that are particularly sensitive to latency and that could be a problem running virtual, but
all the mainstream scenarios are pretty much OK.

How do I use Sun Web Server 7.0u1 reverse proxy to change public URLs?

Some of our installations use the Sun Web Server 7.0 (update 1, usually)
for hosting some of the public resource and reverse-proxying other parts
of the URI namespace from other backend servers (content, application
and other types of servers).
So far every type of backend server served a unique part of the namespace
and there was no collision of names, and the backend resources were
published in a one-to-one manner. That is, a backend resource like, say,
http://appserver:8080/content/page.html would be published in the internet
as http://www.publicsite.com/content/page.html
I was recently asked to research whether we can rename some parts of
the public URI namespace, to publish some or all resources as, say,
http://www.publicsite.com/data/page.html while using the same backend
resources.
Another quest, possibly related in solution, was to make a tidy url for the
first page the user opens of the site. That is, in the current solution when
a visitor types the url "www.publicsite.com" in his or her browser, our web
server returns an HTTP-302 redirect to the actual first page URL, so the
browser sends a second request (and changes the URL in its location bar).
One customer said that it is not "tidy". They don't want the URL to change
right upon first rendering the page. They want the root page to be rendered
instantly i the first HTTP request.
So far I found that I can't solve these problems. I believe these problems
share a solution because it relies on ability to control the actual URI strings
requested by Sun Web Server from backend servers.
Some details follow, now:
It seems that the reverse proxy (Service fn="service-passthrough") takes
only the $uri value which was originally requested by the browser. I didn't
yet manage to override this value while processing a request, not even if
I "restart" a request. Turning the error log up to "finest" I see that even
when making the "service-passthrough" operation, the Sun Web Server
still remembers that the request was for "/test" (in my test case below);
it does indeed ask the backend server for an URI "/test" and that fails.
[04/Mar/2009:21:45:34] finest (25095) www.publicsite.com: for host xx.xx.xx.83
trying to GET /content/MainPage.html while trying to GET /test, func_exec reports:

servers="http://10.16.2.127:8080" Directive="Service" DaemonPool="2b1348"
returned 0 (REQ_PROCEED)My obj.conf file currently has simple clauses like this:
# this causes /content/* to be taken from another (backend) server
NameTrans fn="assign-name" from="/content" name="content-test" nostat="/content"
# this causes requests to site root to be HTTP-redirected to a certain page URI
<If $uri =~ '^/$'>
 NameTrans fn="redirect"
 url="http://www.publicsite.com/content/MainPage.html"
</If>
<Object name="content-test">
### This maps http://public/content/* to http://10.16.2.127:8080/content/*
### Somehow the desired solution should instead map http://public/data/* to http://10.16.2.127:8080/content/*

I have also tried "restart"ing the request like this:
 NameTrans fn="restart" uri="/data"or desperately trying to set the new request uri like this:
 Service fn="set-variable" uri="/magnoliaPublic/Main.html"Thanks for any ideas (including a statement whether this can be done at all
in some version of Sun Web Server 7.0 or its opensourced siblings) ;)
//Jim

Some of our installations use the Sun Web Server 7.0 (update 1, usually)please plan on installing the latest service pack - 7.0 Update 4. these updates addresses potentially critical bug fixes.
I was recently asked to research whether we can rename some parts of
the public URI namespace, to publish some or all resources as, say,
http://www.publicsite.com/data/page.html while using the same backend
resources.> now, if all the resources are under say /data, then how will you know which pages need to be sent to which back end resources. i guess, you probably meant to check for /data/page.html should go to <back-end>/content/page.html
yes, you could do something like
- edit your corresponding obj.conf (<hostname>-obj.conf or obj.conf depending on your configuration)
<Object name=¨default¨>
<If $uri = ¨/page/¨>
#move this nametrans SAF (for map directive - which is for reverse proxy within <if> clause)
NameTrans.. fn=map
</If
</Object>
and you could do https-<hostname>/bin/reconfig (dynamic reconfiguration) to check out if this is what you wanted. also, you might want to move config/server.xml <log-level> to finest and do your configuration . this way, you would get enough information on what is going on within your server logs.
finally,when you are satisfied, you might have to run the following command to make your manual change into admin config repository.
<install-root>/bin/wadm pull-config user=admin config=<hostname> <hostname>
<install-root>/bin/wadm deploy-config --user=admin <hostname>
you might want to check out this for more info on how you could use <if> else condition to handle your requirement.
http://docs.sun.com/app/docs/doc/820-6599/gdaer?a=view
finally, you might want to refer to this doc - which explains on ws7 request processing overview. this should provide you with some pointers as to what these different directives mean
http://docs.sun.com/app/docs/doc/820-6599/gbysz?a=view
>
One customer said that it is not "tidy". They don't want the URL to change
right upon first rendering the page. They want the root page to be rendered
instantly i the first HTTP request.
please check out the rewrite / restart SAF. this should help you.
http://docs.sun.com/app/docs/doc/820-6599/gdada?a=view
pl. understand that - like with more web servers - ordering of directives is very important within obj.conf. so, you might want to make sure that you verify the obj.conf directive ordering is what you want it to do..
It seems that the reverse proxy (Service fn="service-passthrough") takes
only the $uri value which was originally requested by the browser. I didn't

still remembers that the request was for "/test" (in my test case below);
it does indeed ask the backend server for an URI "/test" and that fails.
now, you are in the totally wrong direction. web server 7 includes a highly integrated reverse proxy solution compared to 6.1. unlike 6.1, you don´t have to download a separate plugin . however, you will need to manually migrate your 6.1 based reverse proxy settings into 7.0. please check out this blog link on how to set up a reverse proxy
http://blogs.sun.com/amit/entry/setting_up_a_reverse_proxy
feel free to post to us if you need any futher help
you are probably better off - starting fresh
- install ws7u4
- use gui or CLI to create a reverse proxy and map one on one - say content
http://docs.sun.com/app/docs/doc/820-6601/create-reverse-proxy-1?a=view
if you don´t plan on using ws7 integrated web container (ability to process jsp/servlet), then you could disable java support as well. this should reduce your server memory footprint
<install-root>/bin/wadm disable-java user=admin config=<hostname>
<install-root>/bin/wadm create-reverse-proxy user=admin uri-prefix=/content server=<http://your back end server/ config=<hostname> --vs=<hostname>
<install-root>/bin/wadm deploy-config --user=admin <hostname>
now, you can check out the regular express processing and <if> syntax from our docs and try it out within <https-<hostname>/config/<hostname>-obj.conf> file and restart the server. pl. note that once you disable java, ws7 admin server creates <vs>-obj.conf and you need to edit this file and not default obj.conf for your changes to be read by server.
>
I have also tried "restart"ing the request like this:
NameTrans fn="restart" uri="/data"
ordering is very important here... you need to do this some thing like
<Object name=default>
<If not $restarted>
NameTrans fn=restart uri from=/¨ uri=/foo.
</If>

Hi Iain,
We are using Microsoft Internet explorer 6.0. I am not sure about the 'proxy' (As we don't have any proxy setting in Tool--> Internet options--> connection--> LAN setting). We are accessing the Workspace and FR studio via Citrix application. How can I check the proxy.
Also, I noticed one more point, Report has prompt for seleting 'Account hierarchy'.If we run the report only for one account hierarchy, report is returning the data but while running for multiple account hierarchy, it is throwing the 'Proxy error' as memtioned above.
Please help us on this.

Web-Service Proxy and Web-Service Client access in a Bean (EJB 3.0)

Hello Community,
i want to access the SAP Knowledge-Management via the Webservice "RepositoryFrameworkWS", which resides on our Portal-System, from my Java-Application, which runs on a NW CE 7.11 Ehp1 Java Server.
I choosed to create a WS-Client as a deployable client. So i created an Bean Project, imported the WSDL and created a WS-Proxy in that project. Additionaly i added some beans to that Bean-Project which use the WS-Proxy to access the KM.
So far so good.
But the WSDL also creates a Service-Endpoint, which already has an url for the WS-Target and Authentication-Information (in my case it seems that no Authentication is active) in its body.
Because my client shell run on different systems in the future i searched for a way to easiliy deploy my application and adapt target-information elsewhere. I found in the documentation, that after deploying the deployable WS-Proxy/Client this can be done in the NW-Administrator under SOA-Management->Application and Scenario Communication->Single Service Administration.
To my surprise i found my deployed WS there. And the entry for the there listed Port was configurable. But unfortunatly this customization is ignored by the application. For example i changed authentication to a HTTP-Authentication with a specific user and also changed to Target-URL. But with no success.
What's wrong here?
i accessed the WS in my bean in the following way:
    public Class xyz
     @WebServiceRef (name="RepositoryFrameworkWS")
     RepositoryFrameworkWS service;
      RepositoryFrameworkWSViDocument vi = service.getPort(RepositoryFrameworkWSViDocument.class);
     vi.findResources(rid,....)
regards
Matthias Hayk
Edited by: Matthias Hayk on Sep 15, 2009 10:13 AM

Hi Matthias
In Single Service Administration there are two views: Webservices and WS Clients configurations. First of all you should enable BASIC HTTP authentication in WS configuration. Then go to WS Client configuration and enter user/password in HTTP BASIC authentication settings.
Hope this help.

Error while creating a deployable proxy for a URL in NWDS

Hi ,
There is a requirement for calling a webservice in the .NET platform from JAVA using NWDS. The webservice of the server is pinged using the URL of the webservice. when the URL is passed in the WS navigator of CRD ( that is Development Server) , the response is retreived successfully . The version of NWDS is 7.0.23.
we are facing problem when we are trying to create a Deployable proxy in NWDS by using the following steps :
1) Create a Development Component
2) Select the Deployable Proxy
3) Create the Client Proxy Defintion of the created DC
At step 3 , when we giving the url or WSDL link like "http:// www3.authoring.syngenta/newswebservice.asmx?WSDL" (this is just for example) , it is showing as "Invalid wsdl or wsdl not found " . so that we are not able to procees further.
When we are trying to create proxy the for the WSDL link like " http:// www.authoring.syngenta/newswebservice.asmx?WSDL" , we are able to create successfully.
can anyone suggest why we are able to create the proxy for the URL "http:// www.authoring.syngenta/newswebservice.asmx?WSDL" and not for the other URL.
Any pointers or suggestions are very helpful.
Thanks and Regards,
Sreedevi

Late response I know, but I have solved a similar problem recently and thought I would share.
Firstly, the problem is not with the namespace. The "Namespace ..." part is just stating the namespace the "Incorrect Value" has. So this error is complaining about the value "Unknown" - which isn't very helpful.
It appears the SAP SE80 importer does not like elements like the following because it can't understand <s:element ref="s:schema" />. It appears this is a common thing to be included in .NET generated WSDLs.
<s:element minOccurs="0" maxOccurs="1" name="GetCursDynamicResult"> <s:complexType> <s:sequence> <s:element ref="s:schema" /> <s:any /> </s:sequence> </s:complexType></s:element>
SAP will also not like this example as it does not support mixed content (see: http://www.w3schools.com/schema/schema_complex_mixed.asp)
<s:element minOccurs="0" maxOccurs="1" name="SaldoXMLResult">
 <s:complexType mixed="true">
 <s:sequence>
 <s:any />
 </s:sequence>
 </s:complexType>
</s:element>
You can "Fix" the problem in both cases by removing the offending text in a local copy of the WSDL file so remove line 4 in the first example and change line 2 in the second to <s:complexType> the proxy can then be generated. No idea if the resulting service will be fully operational though!
