Regarding Direct Connections in PI 7.1 EHP1

Hi
I have two integrate two SAP ECC systems using Direct connections I have gone through the WiliamLI Blog
http://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/b00bbb77-75bc-2a10-6b9a-a6f8161515a6?quicklink=index&overridelayout=true
and also the documentation
http://help.sap.com/saphelp_nwpi711/helpdata/en/48/ce5bf1a0d7154ee10000000a421937/frameset.htm
I have 1 doubt
If the proxies are generated on ABAP backend of PI system ( inbound and outbound both as per the blog )
How do I integrate two ECC systems ( Normally proxies are created on ECC system )
Or it is not possible to talk between two SAP ECC system using direct connections and I am going a wrong way
I am confused .
Please help in this regard
Thanks
Ninad

Hi,
You are correct, Instructor has used SAP PI system ABAP stack to create proxies.
Let me explain you how he has used SAP PI system to illustrate the Direct Connection with in PI itself.
-> Created Proxies both Server and Client in PI itself.
-> Uses Client 200 as SYS1 and SYS2 as 300 (see Receiver Communication Channel creation) other than these, he must
      have 001 client for Integration server itself.
->   Executes client proxy from Client 200 and gets data from client 300 as this is the receiver.
->   Used client 200 and 300 as two different ABAP Back end systems (Integration Engines) but they are within PI itself.
->   To create proxy he must have ABAP developer license for client 200.
This never happens in any Implementation Projects, As Rajesh said they will be two different ERP systems which pass through PI.
Hope you understood now.

How can i delay the present of direct connected route?

Hi, I got 2 3550SMI switch interconnecting by Etherchannel. Each 3550 has an uplink to its upstream router (R1-SW1=SW2-R2). R1 and R2 connects to the remote site routers (say R3 and R4).
With EIGRP redistribute connected, R1 update the direct connected network via WAN link A to R3 where R2 does the same thing updating R4 via WAN link B.
The failover is fine after SW2 powered off. However, problem occured when I powered up SW2. During the bootup of SW2, there was carrier signal which brought up the ethernet port of R2 and the direct connected route presented in R2 then updating R4. Some of the traffic had started to come over from R4 via WAN link B to R2 while SW2 is still booting. (or Etherchannel was not yet ready). As a result, workstation connecting to SW1 cannot be reached for those traffic came from R4->R3->SW2.
I have tried to use "carrier-delay 60"on the ethernet port of R2. It seems solve the problem since the direct connected route delay 60sec. Within that 60 sec, no update via EIGRP from R2 to R4 so that all traffic still went through R3->R1. After that 60 sec, SW2 had already bootup and the etherchannel was also ready.
However, i can only do it with C3725 router. I've tried 1750, 25xx, 26xx and 3640-12.3T but the behavior was not expected (route still present immediately after carrier signal detected).
My questions are:
Is that command valid on Eth or FE interface?
Is there any different using that command with diff. router series, eg. ISR (18xx,28xx,38xx)?
Is there any condition that I could make it work? (at least 3725 worked)
Is there any other way to delay the present of that direct connected route?
Thanks.

Hello,
instead of the 'carrier-delay' command, you could try to change the EIGRP hello and hold-time intervals (which default to 5 and 15 seconds respectively on broadcast media such as Ethernet), in order to delay EIGRP convergence. So, on your Ethernet interfaces when you use the interface commands:
ip hello-time eigrp x 60
ip hold-time eigrp x 180
the redistributed routes will show up only after 60 seconds, which effectively does the same as the 'carrier-delay'...
Can you try that and see if that works for you ?

Direct Connectivity to systems source

Please i have a question:
Should the OWB Client (Design component) have direct connection to the system sources, to import metadata, or the import will be executed from server_Repository(design), in this case only the server_side must be connected to the source.
(I read the paper Oracle warehouse Builder 10g Architecture, it discusses about metabase : is this component resides in server or in server(design) ???
Thanks for your help

Hi,
If you have checked the architecture of OWB you've seen the following 3 'environments':
- design time repository (holds model information);
- runtime repository (holds runtime information on deployment and execution);
- target schema (your actual datawarehouse).
The OWB Client interacts with the design time repository.
From within the OWB Client you can start the Deployment Manager (using the so-called Runtime Access User), all things happening here are stored in the runtime repository.
With your OWB Client you need access to the design repository, thus access to the database where this resides (since you have to specifically log in).
From this design repository database you need access to all databases that are used as source for your datawarehouse (via databaselinks).
Hope this helped.

How to send message to direct connected users

Hi,
I am working on a text Chat application with FMS4 "RTMFP" connection and i am looking a functionality to send direct message to one to another peer, please some one help me.
Thanks
Sushil

Below are the lines from above link which you can use for your purpose if your users are directly connected.
Sending Message
// peer2ID is of #2 (Moscow)
var message:Object = new Object();
message.destination = netGroup.convertPeerIDToGroupAddress(peer2ID);
message.value = "Hello I am message from #1";
netGroup.sendToNearest(msg, msg.dest);
Receiving Message
When you receive a Direct Routing message, it comes to NetStatusEvent with code “NetGroup.SendTo.Notify”:
netGroup.addEventListener(NetStatusEvent.NET_STATUS, netStatus);
function netStatus(event:NetStatusEvent):void{
     switch(e.info.code){
     case "NetGroup.SendTo.Notify":
          // e.info.message contains our message Object
          trace("Received Message: "+e.info.message.value);
          break;
But this will work only if #2 is a neigbor of #1.
So if it is not directly connected use forwarding.

SOAP - RFC possible with Direct Connection?

On our PI 7.1 system we have a RFC which we want to expose as a webservice with all the standard monitoring SAP PI provides. On PI 7.0 is used to create a configuration scenario in Integration Builder and generate a WSDL.
I have read the document 'Configuring Web Service Scenarios', but it is not clear to me if i can create a AS JAVA 7.1 -> AS ABAP 7.1 scenario and if the 'Direct Connection'-functionality of SAP PI 7.1 offers me a solution.
Please advise me...

Hi,
in PI7.1 direct connection uses WS adapter which works on WS-RM protocol.............your req is to expose RFC as web-service which do not work on WS-RM protocol and moreover you will require RFC adapter for configuration of your scenario.... So SOAP->RFC is not possible with Direct connection in PI7.1.

WS Adapter - Mandatory Parameters - Direct Connection

Hello Friends,
We try to create create one Pass Through interface between 2 SAP Systems (Proxy to Proxy) using Direct Connection option in ID.
We have PI 7.11 (EHP1). For the receiver system we have created one communication channel of adapter type WS and Adapter Version SAP BASIS 7.10.
In this channel, it shows 3 Mandatory Parameters: 1) Target Host 2) Service Name/Port 3) URL Access Path.
We have entered the Receiver SAP Host name for the 'Target Host' Parameter.
For the 2nd one, do we need to enter Java Port or HTTP Port Number of the receiver?
For the URL Access Path, what do we need enter ? (I read from SAP Help, needs to enter Client Number if it SAP Ssytem. But, If enter this, it did not ask user name and password). Moreover for this Business System in ID, there is no Logon Tab.
Could you please clarify friends?

it can be used for direct connections as we as connectivity to IS.

But I dont think you can use it for ABAP proxy, It is usually for WS communication
for ABAP proxy you can use the XI adapter - http://help.sap.com/saphelp_nwpi71/helpdata/en/43/96cbccb9335b77e10000000a11466f/frameset.htm

Why to Use EJB rather then Direct Connection To Oracle Thru webDynpro?

Hi
Experts,
I want to know that why to use EJB to connect to oracle rather then direct connection via WebDynpro.
Please Give Me References to how to connect to oracle with EJB or WebDynpro.I want to tell you that i know JDBC,JAVA and basic web Dynpro.
Please Reply Me Dear Friends...ASAP.

EJB are better for a project beacuse the application is scalable, have less maintainence and have better performance.
Have you gone throght these:
Connect Oracle 9.2 DB to Web AS 6.40
web dynpro - database connection
web Dynpro application connecting to oracle

Feature request: Allow direct connections for contacts only

Hello, on Windows there is an option "Allow direct connections to contacts only" as described on http://en.kioskea.net/faq/32357-skype-hide-your-ip-from-people-who-are-not-on-your-contact-list. Many people including myself would like to see this feature implemented in the Linux client. There are solutions to protect the IP from resolvers like setting up proxies. However, the performance of free SOCKS-proxies is mostly very bad. VPNs with an appropriate bandwidth also cost an amount of money and additionally, it is difficult to only route Skype traffic through a VPN. Setting up a VM with Windows or WINE just to run Skype is an overkill as well. I consider it inconvenient that this feature is implemented on Windows while - in my opinion - mainly Linux users being aware of security might be in need for this feature. Therefore, I request to implement such a functionality into the Linux client. Kind regards from Germany

If you want to enable that feature on a Skype client that does not offer it in the GUI you would have to do it manually. You can follow the guidance here and the same information applies to the Linux client and any other client you have root or file-level access to. http://community.skype.com/t5/Modern-Windows-from-Windows/Windows-8-IP-Hiding/m-p/2876437/highlight/true#M19476 Linux path:/home/Username/.Skype/YourSkypeName/config.xml

Webservice Vs Direct Connect to DB

Experts,
In our application, we're connecting to legacy application using web service call. Here, I wanted to know the benefit of using Web Service call or direct connect to DB using Open SQL.
Please advice which one is best. Here I was not able to come to any conculsion.
Regards,
Ramki.

Hi,
>Here I was not able to come to any conculsion.
Maybe you could think of what will happen if there is a structure change in a table ? This might help you to come to a conclusion...
Direct external access to a database is EVIL and should be avoided at any price.
By the way, if you access SAP data directly at database level, you loose SAP support...

Direct connecting with parallel cable

I'm trying to get arch linux to do a direct connect via parallel cable to a laptop with windows 98 so I can transfer some files (and I do have the right kind of cable). Can anyone tell me what programs/man pages I'm supposed to be looking at for this kind of thing?
I know some of you are gonna say right off the bat to get a crossover ethernet cable and connect that way, but the laptop doesn't have an ethernet port and I don't want to get a pcmcia card for this.
To make matters worse, the cd drive on the laptop won't work any more, so using cdrs is out too.
Thanks in advance for any advice.

Hi dlanor78 and tgc.
There's a nice PLIP mini-how-to available:
LINUX PLIP MINI-HOWTO
http://www.linux.se/doc/HOWTO/mini/PLIP.htm
You can connect Linux to Linux, DOS, but not Windows 95 (other variants are not mentioned anywhere).
There's some additional information about PLIP in the following article:
Making a Simple Linux Network Including Windows 9x
http://linuxgazette.net/issue57/sipos.html
The author gets around the Windows 9x limitation by installing Bochs and running Linux emulation on the Windows machine.
I first read about PLIP in Multitool Linux (Chapter 4. "Soup Cans and String Last-Ditch Communications Methods").
You'll need a Laplink cable for this to work, by the way.

Win

Direct Connection - Not seen in SXI_CACHE

Hi Friends,
We have created one Direct Connection object in the Integration Directory. (This is for the interface between SAP to SAP System, Proxy --> Proxy).
When I check in SXI_CACHE, this Direct Connection Object is not displayed. (Direct Connection, Assignment, Profile - those objects are not there).
I did complete cache refresh. After this, the SXI_CACHE is green but these objects did not appear.
Our system is PI 7.1 (EHP 1). SP Level is 06.
What would be the problem ?
Could you please clarify?
Kind regards,
Jegathees P.

Hi,
Try to perform a minor change in the object, like in the Description field, then save it, activate it and perform the cache with:
http://host:j2eeport/CPACache/refresh?mode=full
And also with:
- In Integration Repository/Directory go to menu Environment -> Clear SLD Data Cache
- In R/3 go to transaction SXI_CACHE -> menu XI Runtime Cache -> Start Complete Cache Refresh

Caio

Directly connecting a camera to take pictures, not simply download...

I am about to embark on a project of taking a slew (thousands) of small product photos. I would like to direct connect a camera to my iBook so I can take pictures and have them transfer directly to the Mac. Eliminating the step of downloading a memory card (or batch downloading from a camera) would save an incredible amount of time.
Is there a way to do this? I'm open to any and all suggestions. Thanks...

This is called tethered shooting. For this you’ll need a camera that can do it plus the software on your mac. For instance, Aperture and Image Capture can for some cameras. So, the first thing you need to find out is does your camera support this.

Sybase Mainframe Direct Connect

We have a problem regarding Mainframe Direct Connect server.
We have built application using Sybase DirectConnect Client library.
It communicates Mainframe Direct Connect.
When the application is set to SSL enabled, it communicates the Direct Connect using SSL.
When server is not configured SSL enabled, the server does not reject the connection from the app but no action. So, the application is just keep running and even does not get timeout from DirectConnect library.
ct_connect is used to access the directconnect server. Is there any way to configure the server to make timeout from client connection?
I cannot find any timeout setting on Mainframe DirectConnect setting file.
Appreciate your help.

Current system is as below:
Client app (using ct_connect in direct connect client lib) -> Sybase Direct Connect gateway on Solaris -> Sybase Mainframe Direct Connect.
Sybase Direct Connect is not SSL enabled.
Client app is configured to use SSL.
When Client app attemts to connect Sybase Direct Connect gateway, the gateway does not reject the connection from the client but keep opening the connection forever. if I manually stop the gateway, then client connection get closed as well. So, I'm looking for the solution that the gateway not to get frozen but reject the client access if it is SSL connection. I cannot find any timeout option to configure Sybase Direct Connect gateway server.
