Proxy configuration in ECC

Hello everyone,
I am trying to set up Proxy between SAP ECC and PI 7.1 . Below is the steps done.
1. Set up HTTP Connection type G in ECC
2. Set up TCP/IP Connection LCRSAPRFC AND SAPSLDAPI
3. Go to SXMB_ADM --> Intg Server Configuration --> It is defined as below
Role of Business System   :      Integration Server
Corresponding Integ. Server :    upsintra.usa.intra.net
And under Specific Configuration it is defined as below.
RUNTIME     ENGINE_TYPE          HUB     UNDEFINED
RUNTIME     HTTP_TIMEOUT          0     0
RUNTIME     IS_URL          upsintra.usa.intra.net
When we execute SPROXY We are able to connect to ESR and see all the objects but we get the following error below when executing this report SPROX_CHECK_HTTP_COMMUNICATION
The HTTP communication of this application server is not functioning correctly.
When calling the method
IF_HTTP_CLIENT=>RECEIVE
the exception
HTTP_COMMUNICATION_FAILURE
was triggered.
The short text for this exception reads as follows:
Communication Error
Also when we call the proxy from a ABAP report program but do not see any messages in SXMB_ADM in ECC or PI 7.1 it generates a cx_ai_system_fault that "Proxy calls are not permitted on sender or receiver side on the IS (client) "
Please advice if anything is missing or something else needs to be installed.
Thanks,
Teresa

Hi All ,
We are testing ABAP proxy configuration between ECC Dev and PI new system (sand box) .
FYI : Currently ABAP proxy configuration running fine between ECC DEV and PI DEV system .
Now we have to testing ABAP proxy configuration between ECC Dev and PI new system (sand box) .
Pls advise what needs to be done.
thanks

Dear All,
Any relation between SLD and Abap proxy configuration ?
FYI:
1,ECC SLD is running fine with PI DEV sysytem (PI7.1).
2,in ECC SAPSLDAPI RFC destination program id is pointing to PI DEV system .
3,In Ecc LCRSAPRFC RFC destination program id is pointing to PI DEV system .
4, PI DEV system is PI7.1
5, PI Sandbox is PI 7.4 SP06 (note : currently we are testing all the interface , PI scenario in new sand box - it is newly upgraded PI system . )
6.In ECC SXMB_adm -> Role of Business System -> Application system
Corresponding Integ. Server -> dest://RFCDESTINATION (H connection type RFC created in ECC SM59.
Below is my question.
1, Latest PI version required H og G type connection ?
2, SLD (sldapicust,lcrsaprfc,sldapicust,rz70)related information needs to point to PI new upgraded dsystem for ABAP proxy testing in new sand box?
pls advise.

ADFS 3.0 - Web Application Proxy configuration Issue

Hi All,
We are in the process of implementing ADFS 3.0 published to the internet for o365 Federation purposes.
The setup consists of the following
- 2 x windows 2012 R2 running ADFS 3.0 ( only one server presently installed and configured though)
- 2 x Windows 2012 R2 Running Web Application Proxy ( only one server presently installed and configured though ).
There is an F5 Big-IP load-balancer for both internal and external interfaces and it has been configured after a lot of issues with the SNI part on the F5.
So, in short the setup is now a single server hosting ADFS 3.0 using SQL and a single WAP server, however the traffic to these servers are still going through the LB.
Now the issue is that i cannot complete the installation/configuration of the Web Application Proxy server. There is a firewall in between our DMZ and the internal network. I can reach the internal services via the following url and telnet on port 443
to the federation service as well. (ports for 443 and 80) are opened to internal network on the load balancer ip . I can reach https://fs.domain.com/adfs/ls/idpinitiatedsignon.aspx and federationmetadata/2007-06/federationmetadata.xml location as well
from the Web APplication proxy server without any issues or certificate prompts at all.
When i do the configuration for WAP, i use the same account which was used as a service account for the ADFS service internally. If i use a local admin account, it errors out with another message stating the connection was closed.
The certificate on the internal server along with its private key was exported and has been imported on the WAP server . This is not internal CA, instead we are using DIGICERT SSL with SAN Names for enterprise registration and work folders. Hence the CA Chain
issue is ruled out and also this is not a wild card certificate.
When the wizard starts configuring, it does establish the trust with the federation service which is shown up in the event viewer with EventID 391 within 15 seconds i get another event id 422 which states that it cannot retrieve the proxy configuration
and eventid 276 on the Federation server which states the authentication failure. this continues until the servers stops to try configuring the wizard.
I have read all the available threads on the 3.0 WAP installation /configuraiton problem and tried all the steps possible but i am still stuck with this issue.
There is one more part that i noticed on the ADFS server, that the self signed services for the token-encrypting and token decrypting are self-signed certificates. Also, in the certificates it was showing up as not trusted. and i installed them to the TRUSTED
ROOT CERTIFICATION STORE after wich i cannot see any private key showing up when viewing the certificate which means i cannot get the MANAGE PRIVATE keys option when right clicking on the cert to assign read permissions for the ADFS service account.
Should i assign the same SSL sertificate (SAN based for enterpriseregistration & Workfolders) to the token-encrypting and token-decrypting services in ADFS console or should i leave them as self signed ? I did read that self-signed is not recommended for
production environment ? If not the same certificate what are the requirements for the certificate ?
I am not sure what I am missing in the configuration that is causing this issue. The WAP servers are not part of the domain and have also ensured the time synchronization between the domain machine as well.
The service name is fs.domain.com on both the internal and external DNS ( we have domain.com as a zone in DNS internally as well ). I am able to Authenticate inside and from the WAP server when accessing the link.
Could it be a Load Balancer Configuration ? [i will try eliminating this from the configuration]
Let me know if there are any options that i can try to resolve this and get the configuration working.
Cheers,

Does the load balancer pass the certificate session through to the ADFS server or are you offloading SSL. SSL offload does not work with WAP/ADFS integration (at least at the time of writing it does not).
Can you try through the load balancer with SSL pass through turned off please.
Also as ADFS 3.0 (Server 2012 R2) uses Server Name Indication (SNI) then any health checks that run on the load balancer must support this, so if they do not then you need to use TCP 443 checks for a listening port, as doing a standard HTTPS check will fail,
and if the load balancer fails its checks whilst you are configuring ADFS that might be a reason why it has gone offline for you (error 442 is to do with failure to swap client certificates between WAP and ADFS).
Finally, check the June update to Server 2012 R2 (http://support.microsoft.com/kb/2964735) as that has fixed some certificate issues with multiple servers for WAP and ADFS when you don't have the
2012 R2 AD schema in place.

How to call a proxy written in ECC from Neteweaver Gateway

Hi Experts,
We have a scenario in our project where there is a proxy written in ECC which brings inventory data from POSDM system. We need to call this proxy and then send the data to SMP 3.0.
Can the experts guide me here on how to go about doing this?
Regards,
Saket.

Hi Krishna,
Thanks for your response. Let me explain in detail.
This is a enterprise service written in ECC to pull data from POSDM. Now we want to use this service to pull this same data from ECC in gateway to further send to mobile app.
Can you guide on the best way to achieve this?

Automatic Proxy Configuration URL doesn't work on some computers, but Manual proxy can work

It seems that the Automatic Proxy Configuration URL doesn't work, I use the command netstat -a, can't see the connection to proxy server, but manual proxy is ok, and I tested on some others computers, most of these computers can work normally with Automatic Proxy Configuration URL.
For the computer can't work normally with Automatic Proxy Configuration URL, I did below actions
1.Clear the cache
2.update the version of firefox
3.reinstall the firefox
4.use the safemode to run firefox
but unfortunately, still doesn't work.
Can some dear friends give me a big favor for this? Thanks a million in advance!

I have the same problem, just showed up recently - very fricking annoying!!

My internet connection keeps reverting back to using a manual proxy server configuration pointing at 127.0.0.1 Port 55414. I've tried the help regarding the user.js and prefs.js files but still it continues to revert to the manual proxy configuration!

I know how to change my network settings to fix my internet connection, I just select "Auto-detect network settings for this network" under Tools, Options, Network, Settings. However every time I close down Firefox it reverts to the manual proxy configuration pointing to 127.0.0.1 Port 55414.
I've tried all the suggestions under saving your preferences but this hasn't worked so I'm at a loss as to what to do next. If I can't sort this I'll have to revert back to Internet Explorer as this doesn't have this problem!

Hi Chaitanya,
Looks like the ABAP code failed during a call to DB. You would have to sit with ABAPer fot this to debug and see where exactly the exception is being raised. Set a debug point in Proxy code and debug the message. You can use sproxy to test this.

Java plug-in 1.4.1 proxy configuration issue causes JTextField TAB problems

I have an applet that has multiple JTextFields in it. I recently updated my Java plug-in to version 1.4.1, and now using TAB to navigate among text fields does not always work when I first bring up a browser and load the applet.
I've found, however, that if I open the Java Console and hit "p" (reload proxy configuration), and then reload my applet (hit Refresh/Reload on my browser), the Tab key works as expected. I did not have this issue with releases prior to 1.4.1.
Any clue on how I can ensure proper proxy configuration upon initial instantiation of the browser? I've seen the problem in both IE 6.0 and Netscape 7.0.
Note that the reloading of the proxy configuration only appears to be necessary once per browser session.

The navigation isn't working. I click in the first text field to give the initial field focus. I then hit TAB and nothing happens. I have a key listener set up for the ENTER key, and this is also supposed to navigate to the next field via:
((JTextField)evt.getSource()).transferFocus();
To see if there was a problem with my build environment or threads in my application, I came up with the following dummy applet:
import java.awt.BorderLayout;
import javax.swing.BoxLayout;
import javax.swing.JApplet;
import javax.swing.JPanel;
import javax.swing.JTextField;
public class TestApplet extends JApplet {
public void init() {
super.init();
public void start() {
JPanel myPanel = new JPanel();
myPanel.setLayout(new BoxLayout(myPanel, BoxLayout.Y_AXIS));
JTextField textField1 = new JTextField("Text Field 1");
myPanel.add(textField1);
JTextField textField2 = new JTextField("Text Field 2");
myPanel.add(textField2);
JTextField textField3 = new JTextField("Text Field 3");
myPanel.add(textField3);
getContentPane().add(BorderLayout.CENTER, myPanel);
public void stop() {
super.stop();
I then compiled this applet using the following:
javac TestApplet.java
I then put together the following HTML file:
<HTML>
<HEAD>
<TITLE>Test Applet</TITLE>
</HEAD>
<BODY MARGINWIDTH="0" MARGINHEIGHT="0" BGCOLOR="white">
<APPLET
CODE=TestApplet.class
WIDTH=635
HEIGHT=500
ALIGN=left
VSPACE=10
HSPACE=10
>
</APPLET>
</BODY>
</HTML>
The results are the same. I am not able to navigate using the TAB key until I bring up the Java console and then close it again. I would think that if this was a bug in 1.4.1_01, I would have seen it all over the forums. Any help would be greatly appreciated.

Bypass automatic proxy configuration for some websites?

Here's my problem, perhaps someone can help:
I occassionally need to use my university's proxy server to access library materials, etc., through my off-campus connection. So I entered the .pac file (a url) in the Automatic Proxy Configuration box of System Preferences > Network. All well and good.
The problem is, when I want to get more weather details from the weather widget for example, visiting a site like Accuweather.com throws up the login page for my proxy server. Having to enter my university id and password whenever I want to check the weather is guaranteed to drive me bananas.
So is there any way to keep sites like Accuweather.com from demanding I log into my proxy server when there's no reason to, while still keeping my auto proxy configuration in place for when I really need to use it? Anything I can do in Safari about this?
The other option seems to be to reserve one browser, configured with my university proxy, just for doing library research, etc., and another as a general surfing browser. I'd be happy to make Safari do general duty, and configure Camino to use the proxy server, but I can't seem to make this division work, since both use whatever's listed in Network Prefs. I can't tell one to use the proxy and the other not to, they're both controlled by this global pref.
I think I might be able to specify the proxy locally in Firefox, and leave Safari w/o the proxy...But I much prefer the look and feel of Camino...
Any ideas on how to get around this with Safari, or a combo of Safari and Camino?
Thanks in advance for any tips.
iBook G4 800Mhz 12" Mac OS X (10.4.4) Safari 2.0.3, Camino 1.0

Okay, I found the "Bypass proxy settings for these Hosts & Domains" box right under my nose, in Network Prefs. It's explained in this kbase document,
http://docs.info.apple.com/article.html?artnum=301534
Getting closer...
However, using the accuweather.com example, I tried entering the domain name and it still calls up the login in Safari. I even tried looking up the site's IP address and entering that in different forms:
wwwa.accuweather.com
207.242.93.24
207.242.93.*
Still no luck, it calls up the proxy server...

Forward parameters in reverse proxy configuration

Hi,
Looking at the detailed configuration in a reverse proxy rule in SJSWS, I have derived the following conclusions:
1) Where the SJSWS listener has SSL-enabled, reverse proxy works on a HTTPS in, HTTP out basis.
2) Details in the incoming request's SSL header, such as User DN, will be stripped out and remapped into the outgoing request as a custom header, e.g. "Proxy-user-dn".
Can anybody tell me if I have gotten anything wrong above?
We are currently switching over from an Apache/mod_proxy/mod_ssl --> Apache/mod_jk --> Apache Tomcat server setup to a hybrid model where SJSWS is the web server reverse proxying to Tomcat (old apps) and SJSAS (new apps).
My question:
All our apps use the User DN string as the user ID. Previously, we developed a custom module in Apache to read the DN at the Apache level and then rewrite it into the Basic Auth user name header in the outgoing request. The Tomcat webapp will then authenticate the user based on the Basic Auth user name property. Is it possible for me to remap it into something similar here in the SJSWS reverse proxy configuration?
Thanks!
Wong

I am not a reverse proxy expert, but this Object-type SAF should forward userdn
http://docs.sun.com/app/docs/doc/820-1062/6ncoqnq3b?l=en&a=view&q=forward-user-dn
You can look for more such SAFs in this document.

Automatic Proxy Configuration keeps getting disabled for Manual Proxy Configuration

When ever I launch Firefox 3.6.13, the connection settings get reset to Manual Proxy Configuration. I switch the connection settings to automatic proxy configuration and all works fine. Upon closing and re-launching Firefox the Connection Setting is set back to manual proxy configuration.
