Individual business system for ABAP and Java Stack

Hi All,
I need to send message from a system to XI via ABAP proxy and Java proxy. The sender's ABAP and Java proxy use the same message interface to communicate with XI. Should I create one business system for the ABAP stack and one for Java stack of the sender system?
Thanks + Best Regards
Jerome

Are you sending same message type from ABAP proxy and Java Proxy to XI?
If you have ABAP proxy, why do you need Java Proxy? Actually you cannot create any Java proxies on ABAP bases systems. What kind of system sender is? Java proxies are created for pure Java based applications.
Let me know if I didnt understand your question correctly. If so, please explain in detail why you need both proxies and what is your sender application.

ABAP aND Java Stack

Whats the use of an ABAP and Java Stacks in XI? What exactly they are doing for XI?
Thanks.

Hi,
Tha ABAP stack consists of the Integration Server which in turn contains your Integration Engine and Business Process Engine.
The J2EE stack contains the Adapter Engine and your IR and ID run on the J2EE engine.
Ever wondered how and where the XI pipeline gets executed? It happens in the ABAP stack.
All messsages picked by the Adapter Framework running on the J2EE engine are passed to the Integration Engine, which does the routing. The mapping program again gets executed on the Java stack and the rest of the pipeline servies are executed again on the ABAP stack and so on.
Take a look at the XI overview doc to understand this better,

How to connect separated ABAP and Java stacks ?

Hi,
I have installed two separate ABAP and Java Stacks and trying to connect both the stacks together.
As per my understanding, only JCO RFC is the mean of communication between ABAP and Java stacks.
But still even after configuring the JCO RFC successfully, I am unable to view, configure or control
J2EE stack's status from smicm (ABAP).
Would you please suggest me, if there is any more configuration to be done on abap or Java stack side.
Thanks,
Cheers !!!
Ashish

Hi Sunny,
JCO RFC is tested and it is working fine. So no issues from JCO RFC side. Hope you would have read carefully.

Hope I am able to clear your doubt. Java is completely separated stack and not add-on.
Suggest me how can I proceed further on this connectivity.
=========================================================
Hi Olivier,
I am grateful to you for your reply. I understood your point but now except a successful JCO RFC test,
is there any mean to check and ensure that both the stacks are connected properly and ready to use.

CUA for ABAP and JAVA Systems

i have a AS-ABAP System and AS-JAVA system.
Can i have a single CUA for AS-ABAP system and aS-JAVA system or i should have seperate CUA for ABAP and JAVA

Hello Balaji,
Yes, you can connect the JAVA user adminsitration with the Single CUA.
Make use of the JAVA UME feature for this.

THis error was gone when I used the registry cleaner for removing ABAp stack But now question is How do I install BOTH????
May be the instance number is the problem....
In old version of ABap stack we can enter the instance number .But not in SP 9 .Can we change here too?

This file holds the Key of the errors since it checks for the instance number which is given in the log as details.. May be we can change it....
In ABap STack install instead of files as in SP 07 they have created an image and may be this si the reason that
we cannot customize.I have to find a way in order to install it...

i found soltuion myslef THe lates WAS for abap is preconfigured and so its not suitable for abap-java multiple installation

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.

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.

Seperate ABAP and JAVA stack for BI

Hi,
We already have running a ABAP stack with BI 7.0 on Oracle/AIX
We are now going to install the JAVA stack with the following software units (AS JAVA, EP, EPC, BI JAVA) to a seperate AIX server. I do have the following questions:
1.) The installation of the JAVA stack will also create a new database or is it possible to use/connect to the database of the ABAP stack
2.) How are we going to connect the ABAP server to the JAVA server. Will that be with JCO or RfC or something else.
3.) Installing the JAVA on a seperate server, how the handle the user store. Creating its own or can we use the user store of the ABAP such as in a dual stack installation ?
4.) Other issue's what is worth to mention
please advise
Ritchie

Hi Ritchie,
You can have different installation options.Amswers below
1)As you are installing in a different system It will create a sepatate database and the connection will happen through jco/rfc.
2) jco/rfc will be used for connection
3)User store will be selected according to the installation mode mentioned in the installation guide.

Running different SPs in ABAP and Java Stack?

Hi,
we do have a dual stack installation of the Web Application server.
We wanted to update from SP9 to SP12. Unfortunately we had problems with updating the ABAP Stack. The problems are not solved yet.
At the Java side we would like to user some new features of SP12. Can we update the Java stack though the ABAP stack is not updated yet?
Thanks for an anwser
Helmut

Hi
I have tried it - not with this particular combination of packages but it should not matter. SAP made support packages stacks to make i.e. testing easier so of cause they will not recommend different levels - which I wont do either in general. However for a particular scenario/installation that I knows and as an exception I would not be reserved for doing this.
It also depends of what runs on the WAS and how much interaction between the two stacks there is. One example could be running EP on a dobule stack system, here I would not personally be afraid og having a higher Java level than abap.
One question of cause is what's the problem with patching the abap stack? It would always be better to solve this problem first, but sometimes we have to make expetions due to timing and priorities...

ABAP and Java Stack: Which to choose/supported standards and components?

Hello,
I am trying to understand the role of the two stacks in NW. Maybe anyone has a few
hints where I can find answers to the following questions:
- An overview of supported Standards (Java 5 since when?)
- An overview of which component runs on which stack? Portal->Java, Integration Server->ABAP and so on.
- Guidelines when to install both stacks and when to use just one stack? When do I use which one?
- Has SAP an stategy towards an one Stack solution (possibly Java?)
Best regards and thanks for any pointers!
Stefan

An overview of supported Standards (Java 5 since when?)
Go to service.sap.com/pam
Product Availability Matrix will tell you about supported version and platforms.
An overview of which component runs on which stack? Portal->Java, Integration Server->ABAP and so on.
Usually the question goes the other direction: what stacks we need for implementation of a particular function?
More and more products require ABAP backend and Java frontend.
For example Employee Self Service has been transerred from ABAP only ITS based to ABAP backend and Java frontend.
Same with SRM.
Guidelines when to install both stacks and when to use just one stack? When do I use which one?
Same as above, driven by business requirements, not technology.
Has SAP an stategy towards an one Stack solution (possibly Java?)
No. Core business functions are still being developed on ABAP and interface, GUI etc utilize JAVA.

Slava

ABAP and JAVA stack on different SP Level

Hi
We tried to move our XI System on SP 21 and we managed to do so for ABAP stack on 21, while Java is still in 19.
Will it make a difference and any problem will occur, is there any Notes/Link in this regard for a matrix to prove that inconsistency may occur in such case.
Best Regards
Swetank

Thanks Prateek for your reply. Unfortunately we are not able to do so at the moment. As this being Test system need to make sure that any problems will occur on being different SP Level.

Login issue with respect to ABAP and JAVA Stack

Dear All,
we are trying to make an external facing portal which has
   Content Area
   Left Navigation(custom par)
   Login
we are having two servers one is running on ABAP stack and other one on JAVA stack, at different locations.we need to deploy the same portal applications on both the servers.Both the servers are EP7 and SP10
I had downloaded the com.sap.portal.runtime.logon.par.bak file and renamed it and modified it in terms of taking out the TopArea.txt and BotArea.txt from the umlogon.jsp page and uploaded the par in portal and created the ivew for the same.
our requirement is similiar to the funtionality as of SDN External Facing portal.
The iview(logon iview) is added to the anonymous framework page.The iviews on both the servers have the same par.
In case of ABAP stack server,after logon,the respective roles of the user are rendered in the Left Navigation.
However in case of JAVA Stack sever ,after logon, one enters into the portal itself.
We are not able to ascertain what might be the reason for such a behaviour, as the par is same in both the server. Is there any different mechanism, in case of Java Stack and ABAP stack? If so what points need to be kept in mind?
Also would like to know, is the approach correct? or is there any other approach?
Thanks
Gunjan

Hi Michael,
Firstly, I'll explain the complete scenario.
The configuration of the two servers are as below.
1) The server is running on ABAP+JAVA Stack and the data source of UME Collaboration data source is on ABAP System
2)The Second server is running on Java Stack and the UME collaboration data source is Database only.
our portal has the same desktop on both the server. there are no TLN. We have only Masthead, Left Navigation, Content Area and Login. Everything is the same except the above mentioned points.
On the 1st System, when we log on we are able to see our custom Desktop developed by us.
On the 2nd server, when we log on, we are not able to see the custom Desktop developed by us, infact we get the default SAP Netweaver Portal with TLN specific to the Logged in User.
Why are we facing this scenario in the 2nd server, We felt it might be because of the difference in the Stack and Data Source. Are we targeting in the right direction?
Or is it that we are missing some thing or doing something wrong in the UME configurations on the 2nd System.
Thanks

How to determine the sender business system for ABAP client proxy

Hi All,
I have one doubt: when the client proxy sends the message to XI, how could i know what is the sender business system name for it?
Is it the logical system which is reflected in Technical System?
let's say if i have the ABAP system, the technical system is ECC, which has three clients: 001, 066 and 000.
And the client 001's logical system in ECCCLNT001 (all the client proxy is created in this client). In this case, the sender business system name is ECCCLNT001, am i right?
If no, please correct me.
Thanks in advance
Leo

Hi lawrence
When data is distributed between different systems, each system within a network has to be clearly identifiable. The u201Clogical systemu201D deals with this issue.
A logical system is an application system in which the applications work together on a common data basis. In SAP terms, the logical system is a client.
Since the logical system name is used to identify a system uniquely within the network, two systems cannot have the same name if they are connected to each other as BW systems or as source systems, or if there are plans to connect them in any way.
Although SAP does not recommend that you connect test systems to production systems, a test system can have the same name as a production system. This makes copying production systems to test systems a lot simpler.
You are only allowed to change the logical system name of a system if the system is not connected to any other systems, because changing the logical system name would render all the connections to other systems useless.
Logical system names must contain capital letters and numbers only. SAP recommends the following naming convention for logical system names: <System-ID>CLNT<Client>.
