Proxy in 3G Mode

Hi,
We connect our iPad through a special APN to our corporate network. I need to specify a proxy for safari (and other apps) - is there any chance to do that? I only found the WiFi proxy setting - but we don't use WiFi.
Kind regards,
Kreuzer Michael

No, you can not set a proxy in 3G. You have to understand the 3G network as a private network…, however you have to solve that issue on your companies network.
enjoy your magic machine

Executing Proxy in Background Mode

Hi All
Is it possible to execute the proxy in background mode ??
This is for a File->XI->ABAP Proxy interface..the message size is more than 30MB and is getting timed out in the inbound queue of the receiver (abap prxy)after 10mins.
This is bcoz the max runtime for the dialog work process is set to 600secs and we are unable to increase it further.
can anyone help.
Thx in advance
chemmanz

Hi Chemmanz,
You can increase the capacity of processing the message in Admin options.
Go to SXMB_ADM, run Integration Engine Configuration
Change specific configuration and then set the size of the message to be processed against the parameter
MAX_MESSAGE_TRANSFER_SIZE.
Hope this should solve your problem.

ABAP proxy call - Balancing mode

Hi all,
In our process, we call ABAP server R/3 proxy from XI. The quality and production R/3 environment are in cluster mode.
How can I set my HTTP destination (type H) in XI to access R/3 dispatcher in order to ensure balancing as I could have done in RFC destination type 3 ?
Thanks a lot,

Server proxy in background mode using abap?

Hi,
I would like to schedule server proxy in back ground mode using ABAP report. I already have the payload available in XSTRING(binary) saved in Z table. I know how to convert binary string to XML (using FMs - SCMS_BINARY_TO_STRING).
However, is there any way to pass binaryXML(XSTRING) to server proxy (without converting the paylolad to XML and use SAX/DOM parser to populate proxy input structure ) ?
Not sure, if SET_XML(IF_WS_PAYLOAD) method can be used.
Thank you,
Mallik

Hi Malik,

If you think about this, it hasnt sense, a server always need to be alive wainting a communication. If you want to stop the server reception, the middleware system (in this case PI) would need to store the messages for a future server availability, then this would work only with async messages. I dont see right now the utility of this, may be don't overload the ECC system in a work hours, is this the problem?
However, is there any way to pass binaryXML(XSTRING) to server proxy (without converting the paylolad to XML and use SAX/DOM parser to populate proxy input structure ) ?
Are you talking about to do this conversion in a java mapping inside the PI? aren't you?

Cisco WSA : Is it possible to use web proxy in transparent mode without WCCP router ?

Hello !
I would like to use Cisco WSA as a web proxy in a transparent way (without any configuration in client's web browsers) but i don't have a WCCP router. So, is it possible ?
If yes, how to do this ?
Thank you,
Stephane Walker

Hi Stephane
The only alternative to WCCP is PBR (Policy Based Routing). With a simple configuration on the router you can redirect traffic defined as interesting by access list to WSA. On the WSA you need to configure transparent mode (Security Services -> Web Proxy -> Edit Settings -> Proxy Mode: Transparent). You also need to assure that proxy is listening on the port 80 and that HTTPS proxy is enabled (on port 443) if you want to redirect the HTTPS traffic as well.
Sample configuration for Cisco router
access-list 110 permit tcp any any eq www
route-map proxy-redirect permit 10
match ip address 110
set ip next-hop xxx.xxx.xxx.xxx
interface ethernet0/1
ip policy route-map proxy-redirect
xxx.xxx.xxx.xxx is the proxy IP in such case and access-list 110 defines web traffic (HTTP TCP/80) as interesting.
The biggest disadvantage of such solution is lack of failure detection. If the proxy will go down for some reason router will keep redirecting the traffic causing internet access outage.
Routers other than Cisco equipment should also have an option to configure policy based routing.
/Artur
Ps. It's not possible to place the WSA in-line between clients and the internet.

Program code for inbound proxy

Hello,
I would like to ask for your help. I am creating an abap program for an inbound proxy to update tables.
It doesn't get the value listed in the file. In the method section, I have created the following codes:
DATA: receipt TYPE zgiserdata-receipt,
            material_slip TYPE zgiserdata-matslip,
            plant TYPE zgiserdata-plant,
            material_number TYPE zgiserdata-matno,
            new_serial TYPE zgiserdata-new_serial,
            old_serial TYPE zgiserdata-old_serial,
            warrex_date TYPE zgiserdata-warrexdate,
            posting_date TYPE zgiserdata-postdate.
Convert input parameters
receipt = input-GOODS_ISSUE_SERIALIZED_CREATE-GOODS_ISSUE-reciept.
material_slip = input-GOODS_ISSUE_SERIALIZED_CREATE-GOODS_ISSUE-material_slip.
plant = input-GOODS_ISSUE_SERIALIZED_CREATE-GOODS_ISSUE-plant.
material_number = input-GOODS_ISSUE_SERIALIZED_CREATE-GOODS_ISSUE-material_number.
new_serial = input-GOODS_ISSUE_SERIALIZED_CREATE-GOODS_ISSUE-new_serial.
old_serial = input-GOODS_ISSUE_SERIALIZED_CREATE-GOODS_ISSUE-old_serial.
warrex_date = input-GOODS_ISSUE_SERIALIZED_CREATE-GOODS_ISSUE-warrex_date.
posting_date = input-GOODS_ISSUE_SERIALIZED_CREATE-GOODS_ISSUE-posting_date.
Debugged on 'receipt', the value I got is 'This is a string 1' instead of the record that is in the file.
'This is a string 2' for 'material_slip', so on and so forth.
Checked on the XI side that the records in the file is being transmitted without any errors. I tested this through SPROXY. Got the message that is executed with no errors, however, I got the values mentioned above instead of the values in the file being sent to XI.
Can you please help me what needs to be checked in order to have the values that are in the file being sent to XI?
Thank you.

Hi Jho,
>>>Debugged on 'receipt',
How did you try to debug the proxy? I belive you tried debugging the proxy using SPROXY transaction code. If you use SPROXY transaction code by default the values are filled as 'This is a string 1 .. n so on..
I would suggest you to copy the xml payload from XI and then in SPROXY transaction code paste the payload and then trigger the proxy in debugging mode.
Or search in sdn how to debug proxy. You can use that guide to debug proxy real time. Guide is also available in some SAP Note. Dont remember the Note number.
If there is anything else you want to know let us know.

ABAP Server Proxy Issue

Guys,
For a scenario i am using ABAP Server Proxy.
I have successfully generated the proxy object but when i want to put some logic in server proxy by double clicking on execute_synchronous, i am getting nothing and when i am trying to use the toggle button to bring the proxy in editable mode i am getting the message that " you can't edit proxy objects ".
What is the solution....
Regards,

As sheetal said "Have you activated the proxy object properly ".
no i didn't ...
I went to SE24 and selected the class with my interface and activated it..
Process should be : Under Proxy Objects choose your interface and test .
It will show you the class needed to be activated..Finally i activated the class..
and get the ball rolling..
Thanx to Sheetal.

ABAP proxy client call PI with new client 120 in old business system

Hi all
We have a requirement to call PI from ABAP client proxy in synchronous mode via a CRM client 120.
CRM client 100 is already configured in the Business system talked above but now we need the same business system to be configured for client 120 as well.
My question is If we go to the SLD and
|-> Click on Business System
|-> Add new client 120
Will it work or we need to do some extra configuration for communication channel.
Also please let me know how to configure Integration Directory for sender agreement, Receiver Agreement and the communication channel.
Thanks in Advance.

Will it work or we need to do some extra configuration for communication channel.
> since sender is client proxy you don't need to do anything in case of receiver proxy you will be needing reciver communication channel of XI adapter type .
for proxy based communication your application system(other than PI/XI) should be able to make a proxy call to XI or receive a call from XI .for this purpose you need to make some settings at R/3( or CRM level)

IPad's and a IronPort Proxy.

So we've started handing out iPad's to our users. I've been able to setup them up to access our wireless network in a secure manner. My next problem is with getting them to use our web proxies.
We have a pair of S170's that we are using. When I configure the HTTP Proxy settings under the wireless network on the iPad I'm getting some weird behavior. For instance, if I type in www.cisco.com Safari changes the url to https://www.cisco.com:8443. If I leave the proxy settings off I get a message saying Safari cannot open the page. It doesn't even prompt me for user credentials like it would on a PC.
I'm sure other people have run into this. Has anyone found a work around? I've been searching the forums and from what I've found the general consensus is that iPad's are just not enterprise friendly.
Thanks

Im afraid if you want to put iPads through a proxy, put the proxy in transparent mode as the Apps are not proxy aware and its not a great browsing experience in explicit mode.
Apple do not provide great direction on this. In my view iPads are not enterprise ready......and Apple almost want you to build your infrastructure around making them work, not the other way around.
Hope this helps.

ABAP Proxy issue on R3 side

Hi all,
I have an issue on QA server. I send an interface from PI to R3 via RFC, then the RFC execute some idoc proccess and at the end it sends a message back to PI via proxy. The issue is that i see the RFC executed succesfully on R3 (Idocs processed) but i cannot see the proxy message on transacction SXI_MONITOR on R3 side, so no proxy message is sent to PI. I already check the configuration for proxy but it seems it is ok. Obviously the issue is not on PI side.
Do you have any idea why R3 doesn't generate the proxy message?

The scenario is assycronous, because the proxy is executed by the RFC.
This scenario is working perfectly on DEV and Production environment. Basis team made a copy of R3 production on QA, so there is a missing configuration on R3 side, I check the SPROXY transaction and I get an error when i execute the proxy in test mode.
Error on Sproxy:
GET_BUSINESS_SYSTEM_ERROR An error occurred when determining the bussines system (NO_BUSINESS_SYSTEM)
But, when i check the SLD i see the bussiness sistem for PI and R3 correctly.
Any idea?

Webservice to proxy - response back to webservice

Hello expert,
I am working on webservice to proxy scenario. When request to create purchase order received by PI thru webservice, PI will do proxy call to create purchase order in ECC and send response back.
We don't want to send ECC response back to Webservice, but we would like to send positive response back as soon as PI recieve the message irrespective of what happens in ECC.
Need some advise.
thanks.

>We don't want to send ECC response back to Webservice, but we would like to send positive response back as soon as PI recieve the message irrespective of what happens in ECC.
One way of doing is after sending request to ecc, you can code in proxy as response in the same interface with single field element like mesg receiveed and map that response to soap response on the sender side. (in this case you dont really process the soap request in ecc directly. you do it at later or convenient time or after sending success transfer message). Basically you handle logic in abap proxy side.
Mapping 1 soap request to proxy request (Per business requirement)
Mapping 2 proxy response (status : messg received ) to soap response
Rest are all same. Basically you do SOAP (sender) to PRoxy (receiver) synchronous mode
If you dont want to pass the soap request message directly to ECC and within that timeframe want to send successful mesg from pI itself then you have to design to store the mesg temporarily. What will happen if your ecc is down? How do you handle that situation.

N9 automatic proxy configuration not working

Hi all
While configuring a network connection (wifi or 3G), N9 allows to put a proxy in "automatic mode". I guess this is for use with a PAC file, maybe with WPAD mechanism also.
I tried several ways to use it, through wifi mainly:
- putting "auto mode" without filling up the "address" field : no luck
- filled up the address field with the PAC file http address : no luck
i captured trafic on the DNS servers and next hope router and it is clear that the N9 never make use of any of the parameters. no dns request on wpad.mydomain, no tcp connection to pac server
more info on WPAD : Wikipedia on WPAD
my n9 is still PR1.0
anyone with some clue ?
thx

Hi
Same problem in PR1.1
I'm very disappointed because this feature seems to work but actually doesn't. It would be really helpful in corporate usage. Even IOS does the job.
Does someone at Nokia have hints about this ?
Thx

Disadvantage on synchronous proxy compared to asynchronous proxy

Hi friends,
Please tell me any disadvantage on Synchronous Proxy compared to asynchronous proxy.
My integration JDBC to PROXY and PROXY to JDBC. Inspite of using the proxy in syn mode i have used asyn proxy, now i have to give the proper answer y i have used asyn proxy, so please give me any drawbacks of syn proxy.
Thanks in advace
Karthikeyan

Hi Karthikeyan,
The main disadvantage of synchronous communication is for every request there should be corresponding response from the receiver, if for any reason receiver doesnt respond there will not be any further message processing. So, its better to go with asynchronous communication.
Thanks,
Bharath.

ACE SSL Reverse Proxy for multible URLs

Hi,
I am trying to setup an ACE as a reverse proxy (one-arm mode) for HTTPS connections for multiple URLs to multiple serverfarms. From what i know i have two options:
1. Use different VIP for each URL and do
L4 loadbalancing or use a
combination of IP address and port.
2. Use different VIP for each URL, do
SSL offloading and do L7 URL based
loadbalancing.
So with these options i am bind to use different IPs for each site. Is there a way i can use one VIP and then offload SSL and do URL based loadbalancing? From my knowledge we are restricted by the nature of the SSL. The reason is that the SSL protocol is a separate layer which encapsulates the HTTP protocol. So the problem is that the SSL session is a separate transaction that takes place before the HTTP session even starts so there is no visibility of the HTTP header.
Any comments appreciated
George Georgiou

Geroge,
your understanding is absolutely correct.
We need to know the site in order to decrypt te traffic because the certificate is associated to a domain name.
But without decrypting, we can't see the domain name.
So, the only way to know the domain without decrypting is to allocate a single ip to each domain.
There is no other solution.
Gilles.
