AS Java Stack as Add-in to ABAP Stack

We are upgrading SRM 3.0 to 5.0.
We will need to install JAVA stack as add-in to ABAP stack. SRM 5.0 need both ABAP and JAVA stack.
We have one box for DEV and QA and they are installed as separate instance (dual instance).
Can we install JAVA stack for both instance separately?
Or do we have to split the dual instancing development system into two separate standalone system
Please advise
Regards
Manisha

Hi Manisha,
If the box is properly sized I feel that in the same box itself you can have 2 java instances (just you have to take care of the instance number).
Also another point which you can consider is that whether your platform is 32 bit ot 64 bit.
So if it is 32 bit what I recommend is to use new hardware and seperate the instances.
Any how it is possible technicall to have 2 java instances in one server.

Hi Mike
Thanks for your response.
We do not have MCOD installation.
Our DEV and QA installed on same physical same server but they they their own database and separate instance of ABAP stack.
Some concern have been raised that if we install JAVA stack as add-in on DEV instance, QA instance will be impacted. Because you can not have two separate JAVA stack on same server.
Please advise if above concern is true

Separating Java add-in from ABAP Stack server

I have installed an ABAP Stack and added the JAVA add-in on the same physical server. Now I would like to have the JAVA add-in run on a physically different server. ABAP on Server1 and JAVA add-in on server2.
What is the process to move the add-in to the new server? What parameters/values need to be changed?
Thanks!
Steve E.

Hi Stephen,
I think Java Standalone is the only (official) option you have, I don't know the way of physically separating J2EE add-in from ABAP stack in dual-stack systems (you can separate CI from DB, or SCS in the cluster env but not add-in from ABAP).

Mike

Installing Java add-in on ABAP Stack

Hello Gurus,
We have recently upgrade from SAP R/3 4.7 ext. 20 SR2 to ECC 6.0 SR3 on Solaris platform using Oracle 10g. We are on Non-unicode system and on Single Stack i.e. AS ABAP only.
Now as new requirement comes up in organization, we need to install additional Java Stack on upgraded system. Please help me in provide some details to proceed further.
1. Advantages of JAVA Stack (is there any performance issues after installing Java Stack?).
2. How to install Java Stack with ABAP stack in Cluster Environment.
Early response is highly appreciated.

Kshitiz Goyal

There are two issues here:
a) double stack instances are deprecated, they shouldn't be installed any more. Install the Java instance as a separate SID, at best on a separate machine (or on a separate Solaris zone on the same machine). See Note 855534 - Dual Stack and SAP Business Suite 7
b) Java stacks with non-Unicode backends are not supported (see Note 975768 - Deprecation of Java features with non-Unicode Backend)
You may be able to technically install the Java AddIn with "some special DVD" but because your backend is non-Unicode this configuration would be unsupported.
I highly suggest you first convert your system to Unicode before trying to connect them to a Java system.

Not able to work with customized Java roles which were edited in ABAP stack

Hello All,
I am trying to copy standard roles into customized roles (i.e. Z roles) using PFCG in XI system. All ABAP based roles are working fine, but all JAVA based roles are not working. I generated profiles as well. And I check all the authorization objects in both standard and customized roles. Everything look same but customized roles are not working.
And when I check the logs on JAVA stack I found the error which says " User XXXXXXXXXX IP address HTTP request processing failed. HTTP error [403] will be returned. The error is [You are not authorized to view the requested resource.No details available]."
I thought there might be any Jco RFC connections missing between the stacks and I tried to check in Visual Admin, but I was not able to find much info regarding these roles.
Am I missing anything or is there any other way for these roles to make customized roles.
And can any one tell me how to run a trace for JAVA stack activitites as we do in ABAP using ST01. Any help will be rewarded. Thanks in advance.
Regards,
Farooq.

Java roles work with influence of permissions in Application Server which we call actions in UME. As you are aware in PI user master record will be in ABAP stack. So the roles in ABAP stack will be having only RFC connections to JAVA stack for the specific JAVA based role. So you need to edit the permission on Java App Server. For that you need to log on to server through visual admin and then go to services and you will find the standard groups assigned to actions. But I dont remember that under which service you will find them
Under that service you will find some 200 actions. And you have to add the name of the custom created JAVA roles on ABAP to all those actions where you find the standard roles. And its a very very lengthy procedure. So SAP advice to go for customized ABAP roles and Standard JAVA roles.
Hope this answer clears your query.
Farooq.

PI Pipeline Doubt : Pipeline Steps in ABAP stack and JAVA stack

Hello
Can anyone please assist me with which stages steps of the PI Pipeline are executed on the Java or the ABAP stack.
Receiver Determination
Interface Determination
Message Split
Message Mapping
Technical routing
Call Adapter
Also can anyone please provide links relating to the PI architecture diagram describing it from ABAP and Java Stack Perspective and not from the Components perspective i.e. Integration Repository and Directory.
Thanks.
Kiran

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.
Most of XI pipelines 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.
Message, Java & XSLT (under Imported Archives) mappings are executed at Java stack;
ABAP & XSLT (in ABAP stack) mappings are executed at ABAP stack.

Firefighter on ABAP stack

Hello All,
I have a query regarding the Firefighter (GRC V5.2) component in the Access Control Suite of SAP GRC. I heard that Firefighter works only for ABAP stack and not for Java stack. Clearly what is ABAP stack & Java stack?
And is this the same case with Superuser Privilage Management(GRC V5.3) as well?
Regards,

Hi,
Each Access Control product requires the following two components:
A common ABAP-based component that resides on your SAP ERP server. This component is called a u201CReal-Time Agent,u201D or RTA. The RTA accesses data from your SAP system and communicates with the front-end Java component, to allow you to see and make changes to that data.
A Java-based component that resides on your web application server. This component provides the user interface you use to make changes in your SAP database. The Java component sends data queries and revised data to the ABAP component, which connects directly to the SAP database.
In Firefighter , The configurations will be done in abap stack using /virsa/vfat tcode. Only reports can be seen in java front end. But in other Components we do configurations in java stack.
I hope this helps you.Please allot points is this helps you.
Thanks,
Joseph

Shutdown ABAP stack?

Hi,
I need to know whether the Java stack can run without the ABAP stack.
I am running a PI 7.1 system and my system is a bit low on memory.
Since we use a web browser for all development work, I needed to know whether it is possible to only run the Java stack and "switch off" the ABAP stack. This way I intend to free up memory for development.
If this is possible, I would like to know how to "switch off" the ABAP stack.
I am running SAP on Oracle 10.2.0.4 and Windows 2003 Ent Server x64.
Thanks
Prasad

Hello,
In dual stack you cannot stop ABAP stack alone but you can stop java alone by jcmon or SMCIM
for permanant disabling of java engine
by changing below j2ee parameter in instance profile to 0
rdisp/j2ee_start_control = 1
rdisp/j2ee_start = 1
but if you are looking for PI system running you should have dual stack compulsary

How to add abap stack to existing NW Java engine- for XI installation

Hi All,
I am having a netweaver Java Stack installed on my system. I would like to install XI - in order to install Xi ,I guess the system should be ABAP + Java. But since I am having java based engine, I would like to add ABAP stack to it. So, my question how to add an ABAP stack to already existing JAVA/J2ee engine.
So what this process is known as-- Is it upgrading or New Installation. Because I need the guide and CD's for it.
Can any one tell me which Guide(Install/upgrade/Master) wud help me.
Thanks

What are the pros and cons of installing java+abap stack for portal?

Hi all,
1.What are the pros and cons of installing java+abap stack for portal?
2.what effect it does on the ume options to be choosen??
3.for the purpose of integration of r3,bw and crm on portal and crm 4.0 60.2.3 business package which option of stack(java or abap or both)will be good option and which ume option while installation should be choosen?
regards
Rajendra

Hi Rajendra,
The NetWeaver Installation Master Guide offers some good scenarios on the pros and cons:
https://websmp201.sapag.de/~sapidb/011000358700005412792005E.pdf
In a nutshell:
ABAP+JAVA
Pros
- Decrease # of servers required to administer the portal
- Less costly
Cons
- Upgrades could be dependent on ABAP and Java release level
- Additional load on the server due to ABAP stack
- Limited scalability
JAVA and ABAP on separate server
Pros
- Improved performance
- Allows each system to be single-use purpose therefore downtime does not affect other components
- More scalable
Cons
- Adds complexity to landscape
- Additional costs

Can I add a JAVA sneak preview to my installed ABAP trial version

Hello experts,
I have installed the ABAP sneak preview 7.01 and I need to install an SLD to it so i can register my ABAP stack to another SLD.
As i know i have to install the JAVA stack first before intalling SLD, it that right?
Is that possible to add a JAVA stack to my ABAP trial version? i can not find a JAVA sneak preview download in SDN..
Thanks a lot!
Best regards, Charlie

Hi Charlie,
It does say that you shouldn't have another SAP system installed but you can definately install two systems without a problem.
Sapinst should do it for you but make sure that you have different instance numbers and ports selected during the start of the install.
Gingle explains the process well here:

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:

Any help would be appreciated.

System Copy from ABAP Stack to ABAP+Java Stack

Hi,
Is it possible to system copy (homogeneous or heterogeneous) from a system based on ABAP Stack to a system based on ABAP+Java Stack? Is it the normal system copy procedure or something aditional is required to do. Pl. advise. Thanks
regards
Edited by: Abdus Samad on Oct 24, 2008 8:13 AM

It depends on what you want to copy, a system copy will always wipe out the existing target. But if you want to only copy data, you might be able to do a client copy. You can start with this SAP note: [552711 - FAQ: Client copy|https://service.sap.com/sap/bc/bsp/spn/sapnotes/index2.htm?numm=552711]

Whats the difference between ABAP stack, ABAP+Java stack and Java stack

Hello,
I have a nagging doubt about the difference between the ABAP stack, ABAP+Java stack & the Java only stack. I believe that the method of applying the kernel for all the 3 types is different.
Also can we apply the ABAP support packs through JSPM.
Please put some light on this.
Thank you

Hi Zaheer
ABAP Stack
AS ABAP is used to provide the ABAP foundation of SAP NetWeaver.
Part of AS ABAP is the Search Engine Service (SES), which enables users to search for
business objects using Search and Classification (TREX). SES accesses Search and
Classification (TREX) functions through the Search and Classification (TREX) ABAP
client. SES replicates the business objects from the ABAP application to Search and
Classification (TREX), so that it can apply Search and Classification (TREX) search
functions to them. When a user enters a search query, the Search and Classification
(TREX) system responds to it, not the database for the ABAP application. For more
information, see the document Installation Guide SAP NetWeaver TREX Single Hosts /
Multiple Host.
Java stack
AS Java is used to provide the Java foundation of SAP NetWeaver. Among the key
capabilities of AS Java are:
J2EE Engine a J2EE 1.3-compliant application server for running enterprise
applications. In addition to the pure J2EE standard technologies, the J2EE
Engine implements complementary technologies, such as Web Dynpro or Web
Services, that are targeted at supporting large-scale, real-business application
development projects.
SAP Composite Application Framework Core (CAF Core) is a service-oriented
architecture for building and deploying composite applications. It enables
modeling of different service types entity services that represent a domain
model, application services that implement business logic, and external
services that offer connectivity to back-end services by means of remote
function calls (RFCs) or Web services. Usage type AS Java comprises the CAF
Core runtime environment, while design time tools are part of the SAP
NetWeaver Developer Studio.
Web Dynpro is the user interface technology for developing professional
business applications for mobile as well as for desktop clients. Web Dynpro
applications can easily be integrated into SAP NetWeaver Enterprise Portal,
providing a unified layout for the end user as well as enhanced navigation
support. Web Dynpro also allows, for example, the development of interactive
forms using the Adobe document services.
Adobe document services is a set of runtime services that provide a range of
form and document creation and manipulation functions such as:
Converting XML form templates (created using Adobe LiveCycle Designer)
to PDF and various print formats
Setting Adobe Reader rights to enable users to fill in and annotate forms,
save and print them locally, and include digital signatures for authentication
using the free Adobe Reader software
Extracting data from SAP applications into Interactive Forms and transferring form data
back into SAP applications using XML
ABAP + Java Stack
Contains both functionalities.
I hope this helps
Regards
Chen
