Separating ABAP and J2EE stack after an Add-in installation

Hi All,
While I need to migrate an Add-in installation (ABAP + J2EE) to a new machine, there is also a requirement to separate these stacks into two separate instances. Can you please suggest the approach for this? Any suggestions are greatly appreciated.
Regards.

Hi Vincent,
if you want to have a two stack system you better install it that way, meaning two different installation for both.
Unfortunately then you might have some trouble with security after this I cannot foresee.

Benny

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.

ABAP and J2EE-Stacks in SAP WEB AS

Hi,
I have two questions about the technical architecture of SAP WebAS, particularly about the ABAP- and J2EE-Server.
Can someone recommend detailed papers/guides (besides help.sap.com)describing:
1) the management of processes and resources in two parts (ABAP and Java)
and
2) The communication mechanisms between J2EE- and ABAP-server.
What are the problems with JCo?
Is there other possibilities to communicate between 2EE- and ABAP-server.(besides JCO), what is the performance in this case compares with JCO?
Thank you!

Apart from JCO communication between JAVA and ABAP can also be handled using ESA services .
please have a llok at these blogs

DB-API in ABAP and J2EE

Hello!
I have two questions regarding the communication mechanisms between ABAP- and J2EE-Stack.
1)Is Jco the only one solution to communicate between ABAP- and J2EE, or exist other possibilities (if Yes, is there some comparison papers: performance, advantages/disadvantages).
2) Which similarities/differences are in the DB-communication in both Server? (e.g. each Workprocess in ABAP/Serverprocess in J2EE<--> DB-Process)
Which DB-API is used in both stacks?
Thank You!
Regards

Hi, Peter!
For both languages - ABAP and Java - SAP offers a Dictionary (for definition of database objects) and Open SQL (for database independency), you may also in both languages embed static SQL scripts into you code (via SQL/J in Java).
For Java there' s the Persistence-Framework offering three support levels, Vendor-JDBC, Native and Open SQL the last one guaranteeing the maximum support. You may in Java access data - via JDBC and SQLJ - in a relational or - via EJB/CMP or JDO - in a object-relational way.
Performance-Features like Table-Buffering exist also in both stacks.
Please have a look at <a href="http://help.sap.com/saphelp_nw2004s/helpdata/de/61/fdbc3d16f39e33e10000000a11405a/frameset.htm">Developing Java Persistence</a> for more information regarding the Java-Part.

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,

Synchronising ABAP and J2EE accounts

Hi All
We are currently having a small issue with our ABAP and Java stacks on BI, basically when we create a user in the ABAP stack it does not appear in the JAVA Engine unless we reboot the whole thing.
Is there something that needs to be configured - e.g. JCo Connector or RFC
And can the by synchronised immediately or is there a job that needs to run?
Thanks in Advance
Phil

MDM with separated ABAP and Java Instance

We installed SAP ERP system with SRM server and Portal as Java instance.
We use Oracle and have 2 oracle schemas/instances: ABAP and Java.
After mounting of MDM server and DBMS configuraiton (to Java instance) we have the following oracle objects:
Oracle Schema A2I_XCAT_DBS
2 oracle users: A2I_XCAT_DBS (owner of the schema) and MDMADMIN
2 tablespaces A2I_A2I_XCAT_DBS.DBF and A2I_A2I_XCAT_DBS_IX.DBF within the main dbs directory E:\oracle\<sid>\102\database
The used tablespace was set to PSAPTEMP
Questions:
1) How can the DBMS configuration will be removed, because the oralce path E:\oracle\<sid>\102\database was wrong
Unfortunately we would like to avoid merge MDM and Portal data in one and the same tablespace PSAPTEMP
2) Where can we find the oracle configuration for MDM with Java Schema, but using their own tablespace?

Are you basically trying to put a new User Interface (UI) on top of MDM because you do not want to use the standard MDM UI? If so, then yes you could write a custom WebDynpro and use the MDM API. We evaluated WebDynpro as an option, but instead we built a new Adobe Flex based UI that sits on top of the MDM Catalog and it totally awesome! There is a sample on our website (www.simplifying-it.net), but we are making some changes to the look/feel... however, the sample demo on the website should give you an idea.
If you have any questions, please let me know.
Thanks,
Mark

Decouple the ABAP and J2EE

Hi All,
I was installed the Netweaver server on windows 2003 server over sqlserver database. The jlaunch and sqlserver process is taking too much memory.
I would like to decouple the ABAP and J2EE server ......how can i approch this. Is there any way to reduce the memory usage of sqlserver and jlaunch process....?
Is there any solution to that problem...please let me know.
Thanks & Regards,

I would like to decouple the ABAP and J2EE server
I didnt understand the term decouple over here for ABAP and JAVA instance. But however, if you dont want the JAVA instance to start along with ABAP, you can control it through the profile parameter rdisp/j2ee_start.

ABAP and JAVA Stack in the same box

Hi all,
I have installed Java Sneak preview first and after I installed ABAP Sneak in the same box.
Everything is working fine but I noticed a little detail.
My jcontrol.exe service disapeared from SAP Management Console.
I mean before installed ABAP Stack my MMC had 2 divisions in my J2E instance:
server 1 with 2 Process msg_server.exe and enserver.exe
server 0 with 2 Process jcontrol.exe and igswd.exe
After installed ABAP Stack, my server 0 became part of NSP Instance and jcontrol process is not displayed anymore anywhere.
Instead I see now msg_server.exe and disp+work.exe and igswd.exe that of course are Process of the ABAP system.
Does anyone have a nice explanation for this?
Regards,
Mauricio

Hi mauricio,
I was installing Netweaver sp15 both Java and ABAP version on one PC. But it seems they are working.
Can you please tell the procedures to follow, to have good installation?
If I load java version first and then ABAP i get error at step 11.
Did you parttition the drive in to 2 or you installed on the same partition?
Your help will be greatly apprecieated.
Thanks

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

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.

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 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.
