Dual Stack vs Split Stack

Hi Gurus,
We are in the process of installation of CRM 2007 server. We were faced with a choice between Dual
Stack and a Split Stack. To our client, we adviced Dual Stack installtion, while they were insisting on
a Split Stack installation. They finally agreed to proceed with Dual Stack installation, but wanted some
documentation highlighting the pros & cons of the both. Could you give any relevent notes or some
documentation for the same? Thanking you in advance
Regards,
Savan Kumar D.

Uhhhhh,
You wrote :

Now you are asking for documentation of the pros and cons of both. What do you base your advice on if you not know what you are doing now?

Split Stack grayed out

I'm one of the recent iPhoto to Aperture converts, so I ask for help and patience with my question. For the record, I did first look through older discussion to see if this question had been answered.
I have a group of pictures that I imported from a span of a few days that I'd like to split up. When I select the picture that I want to use to separate the group, and go to the Stacks menu, "Split Stack" is grayed out. I'm certain there something very basic here that I'm not doing correctly, but I'd appreciate any help available. Thanks.

You don't ever mention how these images got stacked in the first place. If they aren't stacked you can't of course unstack them.
If they are stacked there should be a number in the upper left corner of the first image in the stack. Is that there? If you select the image are any of the stack commands not grayed out?

Abap+ java stack or Abap stack

Hi All,
How to know whether a system is ABAP+ JAVA stack or JAVA stack.
In our system EP6.0 which is JAVA stack holds JC00 which is a java instance direcory. In BW system we have SCS20 and Dvebg...00 directories is it ABAP+ JAVA stack or ABAP stack with J2ee engine services.
Please suggest me...
Thanks,
Subhash.G

In the forder structuer usr\sap\<SID> if you have DVEBMGS<XX> then it's ABAP and if it's JC<XX>, then it's JAVA. Also if under DVEBMGS<XX> you have j2ee and SDM folder then it's a dual stack that is both ABAP and JAVA.
As for the URL if it's a dual stack then using the browser use the user j2ee_admin and the specified password, else if it is only java then use administrator user and the specified password.
If it's a dual stack you can also login using sapgui.
If in case its single stack AS_ABAP
THere will one be a single node i.e. no message server and enque server. The folder stur would be /usr./sap/<SID>/ and tou would find
DVEBMG SYS folders only.
IF in case its single stack Java server then
In mmc. you will find, 2 nodes one for message server, enque server and the other for the SDM, dispatcher and server0
the foder struct would be
/usr/sap/<SID?
JC><CIno> SCS<no>
Now in case if you have double stack i.e. AS-java and AS-ABAP you would will find these things in mmc
Message server and enque server
disp+work, message server and wp
the folder struct would be
/usr/sap/<SID>/
DVEBMG<no> SCS<no>

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

BRF+ Upgrade from JAVA stack to ABAP stack. Tutorials Required.(Beginer)

Dear All,
We are Proceeding with and Upgrade on our JAVA based Stack to ABAP Stack of EHP6.
The new System extensivly uses BRF+ Techonolgy and SAP Workflows.
Could you please Provide certain Basic links to Start of with it? As of now its totally new CONCEPT to start with in coming time for us.
We have skill set avilable in ABAP developemnt,PI,Worklfows and other ABAP object but not so far in BRF+ concept.
If any Tutorails are avaialble then please share across.
PS: I have not been able to Procure " SAP Press Book Availability (BRFplus - Business Rule Management for ABAP Applications)"
Thanks a lot.
Regards
Vishal

Read the papers etc on the Business Rule Framework plus.
Especially take a look at the online training. But be careful with papers for NW 701. This is an old version and you may find stuff in there that is not relevant for you as you are on a much higher release.
There is also a paper that explains how BRFplus can be used in combination with SAP Business Workflow.
Why can't you get the BRFplus book? On the SAP Press page there is also an online version´

ABAP STACK and JAVA STACK certificates

Hi Fiends,
I have requirement in which I want to use HTTP adapter to send message and apply security certificate. I got from sdn that if I wan to use http adapter with certificate than I have to install certificates in ABAP stack.
My problem is I had one scenario in which I am using BC adapter to send message with security certificate and for that I had applied certificates in java stack and its working properly.
My question is,
Is it possible to use Java Stack and ABAP STACK together..?
I mean is it possible to implement both of the above scenario in same xi system?

Hi Soni,
You cannot use the same certifcates wihch you installed in Java stack with abap stack. You need to install separealy on teh abap stack.
For HTTP communication you dont need to install certificates. You only need when you want to use HTTPS communication. So if you want to use HTTPS communication and want to use SOAP adapter then you can use ther certifcates which is already installed on java stack. But if you want to use HTTP adapter then you need to install in ABAP stack.
Please see this hlep on how to install on the java stack and the process behind it:

Also check this help:

Java Stack and ABAP Stack

Hi Experts,
i am now confused about these two stacks: Java Stack and ABAP Stack.
for IR objects, like DT, MT, SI, MM, SM, Action, Process Integration Scenario
for ID objects, like profile agreements, receiver determination, interface determination,
1. where are these objects stored in? Java or ABAP stack?
and i know Adapter Engine is run on JAVA Stack while Integration Engine is on ABAP Stack.
2. how do they call the objects stored in different stack during processing?

Hi,
1. where are these objects stored in? Java or ABAP stack?
These objects are basically developed on the JAVA stack, when they are activated their runtime version is created on ABAP stack, which you can check in SXI_CACHE transaction.
2. how do they call the objects stored in different stack during processing?
Runtime versions of these objects are responsible for the execution of the interfaces.

How is the interface between the Java Stack and ABAP stack is achieved?

How is the interface between the Java Stack and ABAP stack is achieved?..Please send me the answer to [email protected]

Hi,
By interface, I assume you mean the connection between the ABAP and the Java stacks in a double stack system.
The connection from Java to ABAP is through JCo connections defined in the WebDynpro section of the J2EE start page. So Java to ABAP requests are processed through JCo.
The connection from ABAP to Java is through RFC connections defined in TA SM59. The ABAP to Java requests are processed through RFC.
Refer https://dsd.esco-salt.com/StartPage/documents/integration/3.html for detailed explanation.
The UME can be maintained in either ABAP or in JAVA depending on the persistence.
Refer: http://help.sap.com/saphelp_nw70/helpdata/en/5b/5d2706ebc04e4d98036f2e1dcfd47d/frameset.htm
Check UME data source configuration.

Installing Java Stack and Abap Stack, same machine.

Hi all:
Does anybody installed Java Stack and Abap Stack on the same machine?
I installed ABAP stack first, and am trying now to install Java stack but it seems like at the end of the process, ABAP stack. (is not working now).
Any idea?

Not sure about installing both as I haven't tried either!
Anyway, in theory if the SIDs and instance numbers are completely different, then you should be OK. If you ahev the same SID or instance number, I can see possible problems,
Portal only runs on Java, so in theory any Java system will be OK. NWDW would be a good choice.

Difference java stack and abap stack

hello experts,
Difference between java stack and abap stack

Hi
ABAP Stack
The application data in the SAP system is accessed in
the ABAP stack via platform-independent ABAP programs.
ABAP stack is used to run ERP applications mainly MM,SD,FICO etc
Currently in most of the installation you can found mixed stack(ABAP+JAVA)
JAVA Stack
The Java side of the SAP Web AS is often referred to as SAPWeb AS Java or
as the Java stack.
This central SAP Web AS Java instance consists of two separate
instances plus one special application, the Software Deployment Manager (SDM).
These two separate instances that build the central SAP Web AS Java instance are
a standard SAP Web As Java instance, offering a Java dispatcher process and one
or more Java server processes and the so-called SAP Central Services instance
(SCS). The SCS instance offers two processes, exclusively used by the Java side
of the SAP Web AS: the enqueue services and the message service. These two
services only work for the Java side of the SAP system.
Java Stack is mainly used for SAP Portals and you can host Internet/Web based application written in JSP/EJB ,Java Stack uses Java Threads to run application,
Also, Xi requires Double stack
ABAP + JAVA Stacks
Bcoz some components are developed on JAVA
Some components are developed on ABAP Based.
JAVA:
Integration Builder
SLD
Adapter Engine
Runtime Workbench
ABAP:
BPE
Integration Engine
Integration Engine and the Integration server reside on the ABAP Stack. All the Execution of the IS part will be done on ABAP Stack. we can monitor the processed XML messages also in SXMB_MONI( ABAP Stack)
Adapter Engine will reside on the JAVA Stack. All the IR, ID, SLD, RWB Application are developed on JAVA Stack, so thats why we need JAVA Webstart to run these Applications
All the Adapter related Errors we can see in RWB, Communication channel monitoring( Developed and sits on JAVA stack)
Hope this clears your doubts
Thanks

Dynamic switching between stacked and non-stacked detail groups?

Hi guys,
Is it possible to dynamically switch off/on stacking of detail groups?
I would like to give the user the option to switch between stacked and non stacked

JDev: 10.1.3.2
JHS: 10.1.2.26

Yes and No. No because it is not supported out-of-the-box by JHeadstart, yes because you can do this post-generation and then move the custom code to JHeadstart templates.
However, it is not a trivial thing to build, you can try the JDeveloepr forum for any help, we can help you with moving the post-generation code to custom templates, since that is the JHeadstart-related part of your question.

EHP4 stack 3 Java stack error

HI,
I'm trying to install EHP4 stack 3 on my ECC system and I'm getting an error when it gets to the Java stack load.
I'm getting the error in the PREPARE_JSPM_QUEUE phase
Could not find $ component in SP stack.Check if stack is valid
From researching the problem it looks like there is something wrong
with my XML files that I created through the solution manager?
this is a brand new install so I'm not sure why I'm getting this error. Has anyone seen this before?
Lee

Hi Uday,
Yes. I read this message too but there is no solution or explenation. A brief touch upon connecting Java to SLD which is not explained very clearly and not in any of the EHP documentation which is making me wonder if that is relevant. I have opened a ticket with SAP but have not received a response yet. I was hoping someone else had run into this issue and is familiar with the fix. It seems to be an XML generation problem from what I can tell and there is a prompt saying you can pass this step with a password. But It could also be a Java problem. Any thoughts?
