Connecting ABAP stack of PI 7.0 to java stack of PI 7.1.

Hi Experts,
We have 2 PI servers. PI 7.0 & PI 7.1.
We want to connect the ABAP stack of PI 7.0 to java stack of PI 7.1 due to some urgency and problems.
What all parameters do we have to set/change. Please help
Thanks in advance,
~ Suraj
Can anyone please help?

I guess,
Since you are using java stack of PI7.1,some of its exchange profile information might be pointing to the PI7.1 ABAP stack. So you need to change the exchange profile information accordingly(by pointing it to PI7.0 ABAP) and then restart entire sever (ABAP & JAVA stacks).
>All the RFCs are working fine, but when we send an IDOC from the ECC system to ABAP 7.0, we are getting the following error
RFC secnarios will work, since they work on the concept of ProgramID (JCOServer) which basically registers with the sender. In case of receiver it uses the concept of JCO client for connecting.

to configure acceptance of the ABAP (integrated ITS / WebGUI) saplogonticket on the java stack, just log into the java stack (http://FQDN:50xxx/nwa) and select configuration THe last item in the list is Trusted System... click.
on the ensuing page, click on the add trusted system button --> by querying trusted sytem.
Enter the required data on the page:
system type: ABAP
host name: FQDN
System Nr: your instance number
client (of the productive client)
and a username and pw with superuser priveliges in the system (SAP_ALL/SAP_NEW, etc).
the click next
On the final screen, click finish.
You have now SSO setup between the ABAP and Java stacks. To configure SSO to accept java saplogontickets on ABAP see:

Web Dynpro ABAP - Java stack required?

Hey everyone,
We are currently planning an upgrade to ECC 6.0 and Netweaver 2004s. A source of debate during this planning has been whether or not to install the Java stack in our upgraded system.
I'm an ABAP developer, so I'm really looking forward to using Web Dynpro ABAP. Does anyone know if the Java stack is required to effectively use Web Dynpro ABAP? It seems like the two should be independent...but I just want to be sure.
Thanks in advance!!
Chad

No, you do not need the java stack to run WDA applications. It runs purely on the ABAP stack. You can develop your WDA app in SE80 and run it. It will run in a browser from the ABAP stack. If you have a portal, then you know that this runs on the java stack. Also, your portal is probably not running on the same box as your backend ERP system. If you running a portal, I would suggest installing both the java stack as well as the ABAP stack for you portal to run on. Then you will be able to use WDA to create applications to run in your portal.
So to sum up, the portal runs on the java side, if you have both stacks running under your portal you can development WDA and WDJ applications, which both can run on that same engine. To answer you question, you DON'T need the java stack to develop and run your WDA application, but if you want it to run in a portal, then you need a java stack to run the portal on top of. This can be a completly separate box and a standalone java stack. Did I confuse you even more?

JAVA Stack for consuming and providing Services with ABAP?

Hi Experts,
I would like to know if I need to have a Java Stack when I want to build a Web Application with Web Dynpro Abap and consume Enterprise Services from the Enterprise Service Repository. Additional own created services in ABAP should be provided. Is a Java stack necessary for that? Or is an ABAP Stack enough?
Thanks a lot for your answers?
Best regards,
Ingmar

Hi Ingmar,
You do not need a Java stack to build or run Web Dynpro ABAP application. Web Dynpro ABAP runs on ABAP stack.
Just to consume a web or enterprise service from Web Dynpro ABAP application, or any ABAP application for that matter, you do not need Java stack, either. NetWeaver Application Server contains a component called ICM (Internet Communication Manager) that enables the AS to play both as a service provider as well as a consumer.
The part about consuming Enterprise Services from the ES Repository is more complicated, though.
ES Repository is only a modeling tool. Services are actually implemented in the respective backend systems and then registered in central Services Registry. So, if the Enterprise Service you want to consume comes from an application that runs on Java stack, although I do not have any example of that handy, then obviously - Java stack is needed. This is irrelevant, however, if your question only pertains to the consumer part.
I hope this helps.

ABAP and JAVA stack together?

Hello Friends,
I wanted to install the ABAP stack SP12 with JAVA stack SP09. I am downloading the last file of the stacks. Is it possible to install them together on one OS(I have W2K Enterprise Edition)?
Can you guys please help me out here ?
Best Regards,
Fatih Koekce.

Hi
Basically ABAP and Java patches would be inpendent of each other except the Kernel.
You can apply them together as Java patches are to be applied through JSPM and ABAP patches through SPAM, but it is usual practice to apply ABAP patches first and go ahead with Java stack. Because Applying them together would use considerable amount of system resources.
Hope this is helpful.

How to enable ping service on java-stack only system

I have installed SAP NetWeaver 7.0 - Java Trial on local host.
How can you activate the ping service there?
It should work under "http://localhost:50000/sap/bc/ping"
(I know how to activate it with transaction SICF in an abap system, but I have java-stack only here, so I can't call transactions. I can only use the Visual Admin, right?, but there I could not detect a ping service so far)
More detailed:
I created system "SAP_WebDynpro_XSS". (this is necessary for connecting to ECC abap backend for ESS Packages) and set following parameter:
template:"SAP system using connection string"
     category: Web Application Server
          Web AS host name: chrisSAP:50000
          Web AS path: /webdynpro/dispatcher/
          Web AS protocol: http
But when I test the "SAP Web AS Connection" for this system, I got following error:
7. The Web AS ping service http://chrisSAP:50000/sap/bc/ping was not pinged successfully. If the ping service is not activated on the Web AS, you can try to call the ping service manually.
8. An HTTP/S connection to http://chrisSAP:50000/webdynpro/dispatcher/ was not
obtained successfully; this might be due to a closed port on the Firewall.
I guess step 8 did not pass because step 7 failed, and not because of a closed port or firewall (I made sure everything is open.)
The strange thing is that the connection test fails, but the connection seems to work fine!
I mean I can see the front ESS page in the portal when logging in with an ESS-user, and there are no errors in the log. If I change the SAP_WebDynpro_XSS parameters to some other made-up values, then the front ESS page does not come up and some errors appear with "SAP_WebDynpro_XSS" inside.
That proofs that the connection is working despite the failed connection test, right?. But what can I do that the connection test passes? It seems that somehow SAP has hardcoded the path "/sap/bc/ping" which usually exists on an abap system. But I have java-stack only, so how can I tell that the function that runs the test?
A system connection test fails, but the connection is working fine!
If someone could explain that to me...

Dear Srini Nookala,
thank you for your answer. Unfortunately I don't understand the relation of my question to your answer.
>> check with OSS note 1019335 SAP NetWeaver AS Java 6.40 SP21
I have Version 7.0 SP14. I read the OSS note, but there are around 100 changes listed. I read them all, but couldn't figure out one that has to do with ping and system test. So which sentence inside the note are you referring to?
>> The problem is due to JCo parameters configuration not properly, Ask Basis team, they will do it.
I am basis team. I configured the JCo properly as described in manual and tested them afterwards. They run successful. Also all the links that you gave refer to JCO connections about how to set them up and test them. But what have JCO connections to do with System-connection tests? As far as I know JCO-connections are not used for system connectivity tests. You can set them up independent. I understand that JCO-connections are used for getting data from backend servers. But the system "SAP_WebDynpro_XSS" is defined for determing the webdynpros on localhost (frontend, not backend).
So please can you explain me what JCO-connections which refer to remote hosts have to do with a ping service on local host that cannot be reached? And which part would be not configured "properly"? Timeouts? user?
To define my question more properly:
Is it possible to make the connection test work on a java-stack only host for a system that refers to itself (localhost)? Or is it a known bug?
Some sub-questions
Am I using the right system template (I am using "SAP system using dedicated application server")
I have no abap on local host (chrisSAP). Only java stack. Usually path ..sap/bc/ping refers to an abap system, right? So in my opinion I have 3 possibilities:
- install abap-stack on local host (portal) and activate ping service.
- somehow install a ping service that runs under the given URL in Visual Admin (how?)
- somehow tell the connection test to skip pinging and continue test. (How?)
Any additional advice would be highly appreciated.

Java Stack and Client

In the ABAP stack "client" is a very important concept.
Why there is no "client" concept in Java stack? When I login to java stack, why there is no entry for client?

Hi,
you can have multiple clients in an XI system but only one can keep the role of the Integration Server. All other clients may act as application systems (most probably not done in reality).
In a double-stack installation the J2EE engine is always connected to one client in the ABAP system. In a XI system this is always the client where the Integration Server is running.
The reason why there is no client conecpt in a J2EE engine is that only java applications are running there. There are no tables containing business data as we know this from ABAP.
Hope this helps,
Juergen

Java Stack for Web Service in R/3

Hello Friends,
I am developing a Web Service in R/3 server. Developed a RFC and converted it to Web Sevice.
My question is, is it necessarily required to have Java Stack in my server or will it be enough to have ABAP Stack. My server doesn't have java stack installed. shall i be able to run my Web service with ABAP stack?
Please help me and give me some suggesions.
Kumar.

Hi Kumar,
the above answer is simply incorrect.
You can certainly provide a web service from the ABAP stack without any need for a Java stack.
There are several blogs, and lots of forum posts, that discuss how to do this.
If you have indeed "Developed a RFC and converted it to Web Service" then you are away.
Use transaction SOAMANAGER ( or WSADMIN, WSCONFIG on earlier releases) to publish your webservice and away you go.
Cheers

Java Stack for Central monitoring system

I believe for central monitoring with only ABAP stack is sufficient to monitor both remote ABAP and JAVA stacks. For this purpose CCMS and GRMG can be used. My questing is there any need to have JAVA stack in central monitoring system? If yes, what are the things that only ABAP stack can not do alone and JAVA stack is required in central monitoring system?

Hi,
>
> it also mentioned about creating CSMREG user, but it did not say in which client this activity needs to be performed, and there are lot many steps in which there is no mention about the client of solution manager in which we have to perform the configuration.
>
You should created this user in working client.
> Can you guys please help me to configure properly?
>
> One set document which I saw talks about the configuration using RZ21 and other document discuss about Configuration using System Monitoring Work Center, which one do we need to follow, are both methods are 2 different options doing the same thing, can you please clarify?

You can use RZ21 or System monitoring through work center. From Solution manager 7.1, you need to use work center only. So, I would suggest you to use work center only.

Can we add Java Stack after complete installation

We have already installed SAP ECC 6.0. While installation, we had opted only for ABAP stack. Can we add the Java stack now?
Regards.

Hi,
Yes you can install java server on existing ABAP but
If you have an existing ABAP central instance + ABAP dialog instance and
you want to install Java Add-in to the central instance, you first need
to uninstall the ABAP dialog instance, then Install the Java central
instance add-in and then install an ABAP+Java Dialog insntance.
Please refer ABAP+Java instalation guide.
Best regards,

Appreciate your quick response.

Hi Yadagiri,
Please check the reply from Carlos in the below thread
Re: increasing heapsize of java on WINDOWS 2003
Also check your sm59 RFC destination, i guess there is some problem.
Delete AI_RUNTIME_JCOSERVER(RFC connection between the Java engine and the ABAP engine) and create it again.
Hope tht will resolve ur issue...

Connectivity between ABAP and Java Stacks for BI

Dear all,
our BI developer have to use BW Analyser for showing and changing of BW reports in Java based NetWeaver Portal.
Initially just ABAP stack (SID DCE) was installed. In Februar 2014 I installed also an Java Stack (SID JCE) and got dokumentation for
connection to ABAP Stack from SAP Support, it is attached. Further help from SAP Support is not possible, they mean that this
case belong to consultion issues.
Follow activities were sucessfully done:
1. RFC connection DMSAPERP4DEV_PORTAL_JCE was created in J2EE engine
2. RFC connection DMSAPERP4DEV_PORTAL_JCE was created for Portal
3. Portal Server Settings were maintained for portal
4. Singe Sign-In in BI was maintained
5. BI Certificate was imported from BI
6. Portal Certificae was exported from Portal
7. Portal Certificate was imported into BI.
By processing of attached SAP guide it was a problem at step 7 "Create BI System in the Portal"with the
creatig of BW system name. Under "System Administration -> System Configuration -> System Landscape"
I found no systems which are maintained with the Portal Content Studio. I take a template "SAP_R3_Dedicated"
but can not change the system name to "SAP_BW", it is still "Dedicated Application Server for R/3 System". All other
properties was set fine.
At step 8 of mentioned guide I face the next problem - there is no system names under "SAP Reference System"
under "Administration -> System Configuration -> Configuration for User Management", because the system
name on the step 7 could be not set correct, so I can not choose any.
Please advice how to proceed here.
Thank you and best regards

Hi,
It clearly says the problem is with virtual memory. SO you need to change your virtual memory settings using configtool.
See the relevant note.940893
Make changes in the VM parameters for Bootstarp, Dispatched and the server nodes. Your -Xms should be less than equal to -Xmx.
Restart the cluster then.
It should work.
Do reward good points.

Testing SSL Connections, differences between ABAP and JAVA stacks

Hello,
   I am trying to test an outbound SSL connection to a partner.   I already have multiple outbound connections to many partners, but this new one is causing an issue.   Our firewalls between the two sites are opened as required, I verified that I can telnet to the 443 port of their sever.   I then attempted to connect to their URL, via a Java SOAP message, and it is rejected. Some kind of error regarding our handshake.
   In an attempt to troubleshoot the issue I entered their URL in SM59 as a HTTPS connection, tested it, it worked fine.   Which indicates to me that the ABAP side works fine.
   I do the same on the Java stack, via the SOA Manager: Destinations, and it fails.
"Error during ping operation: Error while silently connecting org.w3c.www.protocol.http.Http.Eception: Peer sent alert: Alert Fatal: unexpected message"
I was thinking that maybe the remote partner only allows specific types of SSL version connection, and the Java side is too low. i.e. the partner only allows TLS v1, and we are attempting to use SSL v2.    Is there a place to set this on the Java side? I know I can set inbound parameters on ICM via SMICM.
Any help or assistance would be most appreciated.
Thanks,
Michael Montone

Hi,
I suggest that you verify if you use the same release of the SAP Cryptolib for the ABAP and the Java stack.
This could explain a difference of support for SSL or TLS.

Olivier
