Portal on Internet IP and R/3 on Local IP

Hi,
I have the Portal that is located at an intranet IP Address and Also has an internet IP, but the R/3 just has an intranet IP. So when I try to connect from the Internet to the Portal is ok, but When I tried to execute an Iview it doesn't work. I think is because the iview is trying to connect to an internal IP (where is located the server of the R/3).
Any Ideas?
Thanks!
Matias.

Hi,
I can think of 2 possible reasons
1. Firewall between portal in internet and R/3 in intranet. In this case you need to open up firewall ports for the iView to work.
2.. The domain of Portal and the domain of R/3 system may be different. SSO will not work. Try user mapping
Hope this helps.
Thanks and Regards,

Error while accessing portal via internet

Hi all,
I am having problems when accessing portal through internet. I have installed NW04 SR1(WAS, EP & KM). Then I created some iviews and pages.
Now when I open the portal through internet(using its ip address) and try to access PCD, it is showing undefined in place of the loading message and it is not loading anything. Also the detailed navigation is empty in all pages(eg. System Administration, Monitoring, etc.). But when i access it locally(using machine name) everything works fine. Any idea what the problem is?
Another problem is with the KM Navigation IView. I have created a custom layout set for this iview. In the iview I am displaying the documents in a folder along with a link for approval process. But when i click on the link, it shows javascript error "Access is denied". This happens when I access it through internet. When I access it locally, it works fine and show me the context menu for approval. Any idea?
Please reply fast as it is urgent.
Thanks in advance.

External portal capturing internal portal URL in Log and trace file

Hi,
We are facing one issue in portal like we have two portals for internal (Intranet) and external (Internet) users.
Once users logged in the application and try to get the information about mylink from the external portal link (internet) they should not get any information about the internal portal.
But in log and trace file we can see the external portal link capturing the internal portal URL.
We need to find, from where system capturing the internal portal URL.
Thanks.

The tkproffed trace file is in seconds.
"set timing" is in hh:mi:ss.uu format. So 00:00:01.01 is 1.01 seconds.
You have to remember that most of these measurements are rounded. While your trace file says it contains one second of trace data, you know it's more.
One excellent resource for trace files is "Optimizing Oracle Performance" by Cary Millsap & Jeff Holt. (http://www.amazon.com/Optimizing-Oracle-Performance-Cary-Millsap/dp/059600527X ) I thought I knew trace files before, but this book brings your knowledge to a whole new level.
There is also an excellent WP by Cary Millsap ( http://method-r.com/downloads/doc_details/10-for-developers-making-friends-with-the-oracle-database-cary-millsap ) that gives you some insight.

Exposing Portal over Internet

Hi,
We have implemented SAP modules like SRM, BI and HR in our landscape and Portal is the single point for accessing all the available functionalities. Now, we want to access the portal from Internet WITHOUT MAKING OTHER SYSTEMS accessible because of security reasons. With this, I am not able to access SRM applications because it tries to connect to Web AS of SRM system as configured in System Object of Portal.
Please let me know the way or method used in accessing Portal over Internet.
Thanks,
Iftekhar

Hi Iftekhar,
The ideal scenario should be configuring a reverse proxy which can be place in a DMZ zone. The Reverse proxy will be use to write the rewrite rules.
Also to ensure the security a SSL implementation is highly recommended.This can be through out the landscpe or from the internet cloud to the reverse proxy depends on the requirement.
You can find a tons of material in SDN for configuring reverse proxy and SSL in the landscape.This could be starting point for configuring reverse proxy.
[The Reverse Proxy Series -- Part 1: Introduction]
and for SSL you can follow this [ADS SSL configuration journal I. / ABAP -> JAVA / 640 - 70x]

                                                                                       imdb

                                here are the ones that partially worked: the blaze (works on videos that originate from you tube, but not from news stories)
                                                                                          bing (work on videos from their video section - entertainment type, but not from news videos)
the common thing here seems to be that news type videos crash and entertainment type don't. also videos seem more likely to crash on internet portals like yahoo

Does the portal utilizes Internet Explorer's ADODB.Stream object?

Does the portal utilizes Internet Explorer's ADODB.Stream object? We're attempting to understand the impact associated with disabling the ADODB.Stream object within Internet Explorer as recommended by Microsoft - http://support.microsoft.com/default.aspx?kbid=870669. We have 4.5 in production, and will be migrating to 5.0 in the fall (with full product suite).

Hi
1. yes , please check for host entries
2. please check with your network team and ask them about whether Port has been opened or firewall or not.
3. i was just asking about URL so that i can tell you exact Portal Port. anyways it might be
5<instance number>00 or if in any case if you are using Webdispatcher then it might be 8<instance number of webdispatcher>0 .
9 you can get the root cause of issue with Telneting the port of your Portal from your machine
Goto Command prompt of your machine
and put following command
telnet <ip of portal instance> <port of your portal>
Port will be like
http://portal url:port/irj/portal.
and please also try with IP in IE
http://IP:Port/irj/portal.
if you are able to get it with IP then there is a issue with your Own computer's Host entries
they are at
c:\windows\system32\etc\drivers\hosts

Images not loading while accessing portal from internet

Hi all
we are trying to publish the portal on internet. We have used apache as reverse proxy and it is in dmz .
When we access the portal from internet we are getting the login page but it is with out images (e.g branding imag etc).
we also could login in the portal but we only see the links for Help Personalize Log off , Histrory Back and Forward remaining page is blank.
Is this reverse proxy configuration issue?
Can any body help us in resolving this issue.
Regards
Rajendra.

Hi Rajendra/Experts,
We are currently working on custom webdynpro application which needs to be exposed to Internet using Apache HTTP Server.
We can able to access URL, but no images are getting displayed and also the application not functioning when we click any button/links.
Below is HTTPD file configuration
ProxyPass /esampleApp http://hostname:port/webdynpro/dispatcher/local/esampUI/ESamplingApp
ProxyPassReverse /esampleApp http://hostname:port/webdynpro/dispatcher/local/esampUI/ESamplingApp
when we look in to images URL which is being called from Apache we found out "webdynpro" is missing in the URL.
Actual URL in Portal Server: (working)
http://portalhostname:port/webdynpro/resources/local/esampUI/Components/esampling.ui.ESamplingComp/logo.gif
Apache URL:
http://Apachehostname:port/resources/local/esampUI/Components/esampling.ui.ESamplingComp/logo.gif
Please suggest.
Thanks

Portal Security (Internet-Intranet)

Hi,
I have set up the portal on an intranet. Now I would like it to be accessible from the internet.
As far as I know I have to set up DMZ for that. (De-melitarized zone) for that.
Could someone help me out with that with help/documents.
Regards,
Shobhit

Hi Shobhit,
you do not need to setup a DMZ to make your portal accessible from the Internet. To make the portal accessible from the Internet you just need to make sure that Internet based clients can connect to IP of the portal server, or resolve and connect to the portal server's DNS. Therefore, this is indeed a network configuration issue.
The DMZ is a recommended but not a mandatory security feature for the portal. The idea behind setting up a DMZ is to protect your portal server by adding an additional security layer in your network landscape with traffic and connection filtering application level gateways, IDS systems, etc. that can ward off potential security threats. Also, depending on your security needs, you can use a DMZ not only for internet, but also for intranet connection requests.
As far as documentation goes, you can start off from the Network Security section of the SAP NetWeaver Security Guide, which is available at service.sap.com/security.

Yonko

Portal on internet

Hi Gurus,
Can any body tell me
how to put portal on internet using External facing (EP7.0)
if any body have documents please help me
Thanks and Regards,
Kishore

Hi Kishore,
Please go through these important FAQ regarding External Facing Portal. I am sure that will vary helpful for you.
Q: What is an external-facing portal?
A: An external-facing portal is an implementation of the SAP NetWeaver Portal as a public Web site.
An external-facing portal is open to the internet, providing content to anonymous users, internal employees and business partners and enabling users to self-register in order to access additional content and to personalize the portal.
An external-facing portal uses features of the portal that provide Web-like behavior (for example, use of the browser navigation buttons) and reduce the amount of resources required to view portal pages.
Although not always appropriate for certain resource-rich applications, the external-facing portal can boost ROI by using the same platform for the company's internet and intranet implementations.
Q: What version of NetWeaver do I need to implement an external-facing portal?
A: SAP NetWeaver 04 SPS 14 or higher, or SAP NetWeaver 2004s SPS 6 or higher.
Q: Where can I find documentation about implementing an external-facing portal using SAP NetWeaver Portal?
A: The most current documentation is available on the Help Portal (help.sap.com) at:
SAP Running an IT Scenarios at a Glance NetWeaver 2004s: SAP NetWeaver Library Implementing an External-Facing Portal.Enterprise Portal
SAP NetWeaver  Portal  People Integration  SAP NetWeaver 04: SAP NetWeaver Library Implementing an External-Facing Portal.Special Topics
Q: Where can I find the limitations of implementing an external-facing portal using SAP NetWeaver Portal?
A: SAP Note 877188 and SAP Note 853509.
Q: Why shouldnt I use the external-facing portal for internal implementations?
A: It is recommended not to use this solution for internal use because some functionality that is commonly used for internal implementations is not supported.
Specifically, session management and WorkProtect mode are not supported as they require the use of the client framework JavaScript. Therefore, some standard SAP content such as Web Dynpro, SAP business packages and KM (especially collaboration) that uses these features are also not supported.
In addition, to get the full benefit of the performance improvements in an external-facing portal, the content must be light and supported by the light framework page. Content in internal implementations generally does not meet these requirements. For more information on recommended content for an external-facing portal, see the Content section.
Q: Should I use the provided light framework page for my external-facing portal implementations?
A: Your external-facing portal should use the light framework page, but we recommend that you customize or replace the out-of-the-box navigation iViews within the light framework page. You can easily do this with the Navigation and Framework tag libraries.

SSO failing when sap transactions are accessed in portal thru internet

Hi,
We are accessing portal through internet on reverse proxy(Apache) but the SSO is failing when accessing sap transactions in portal but other screens(ESS) are accessible. Please let me know does this require any config settings in portal or apache side.
thanks i advance.
Marcus

Hi Rajender,
I tried doing the same in the ECC system but the iview is throwing error"resource not available".
We have given just an Apache Ip address in the format <ipaddress>:80 as we doesn't have FQDN for the apache in the place of WebAs and ITS Host name.
Also the WEBAS path is /sap/bc/bsp/sap and ITS path is /sap/bc/gui/sap/its/webgui. Does this require any modifications.
Please also let me know for any changes need to be done on the httpd.config file on Apache server.
portal.xxxxx.xxx.xx - Our External URL
hostname:port/irj/portal - Our Intranet URL
Please let me know the exact format of the entries to be made in ITS and Web As settings with the apache details.
Web AS Host Name : Hostname:port
ITS Host Name : Hostname:port
ITS Path : /sap/bc/gui/sap/its/webgui
thanks in advance

YouTube will not work on safari for me on the ipad. Is there anyway to fix this? I can go anywhere else on the internet fine and it works on google chrome, but on safari it shows a blank screen with the bar on top after it loads.

YouTube will not work on safari for me on the ipad. Is there anyway to fix this? I can go anywhere else on the internet fine and it works on google chrome, but on safari it shows a blank screen with the bar on top after it loads, if it's even loading at all.
I do not know if it's relevant or not, but I got a message on my ipad while on safari saying that my iPhone has a virus. I looked it up and it seems it might have just been an ad from the website I was on, but it happened around the same time YouTube stopped working.

You will find that using the YouTube app will provide a better viewing experience for YouTube videos.

Using Remote app on iPhone 5 without a separate internet connection and wifi router.

Hi,
I need to be able to control iTunes within my MacBook Pro remotely. Using my mobile broadband service and wireless router I've been able to get the Remote app to allow my iPhone 5 to do the job nicely through Home Share. So I went and bought a separate WiFi router and tried to do the same thing. Of course when it didn't work, I discovered that I need an internet connection and WiFi network to make the Home Sharing work.
So I got to thinking, can I create a WiFi hotspot using the Personal HotSpot functionality of my iPhone, set up Home Sharing on phone and MacBookPro and then use the Remote app. Ideally this would work as it seems all the key components are in place.
The MacBook Pro accepts the iPhone hotspot as a means of Home Sharing, however the iPhone won't use the personal hotspot to Home Share and I can't connect to the iPhone personal hotspot on the iPhone itself.
Does anyone know how to make this work for me? It would be such as neat solution if I can get it to work - not to mention the potential to save me about $200 (I need to set this model up for two people).
Cheers
Kathy

Same trouble here, iPad 2 with latest OS and remote app, iPod with latest OS and app.
