PI 7.0 Installation : Physical separation of ABAP/Java stack !?
Dear forum users.
The system administrator of my customer would like (if possible) to separate physically both abap and Java stack on 2 machines for all XI system in the landscape.
The goal is to optimize the clustering UNIX installation (I'm not expert of this part)
=> optimal high availability. (...)
I just want to check near you if this can pose problem regarding XI operating way.
From my point of you, it complexifies a little configuration steps but Is there another impacts ?
PS : A master central SLD is envisaged and a second slave one on the XI production server.
Thanks a lot in advance for your precious help.
Thanks a lot.
For information
Our central SLD is on a standalone system
However slave SLD (to ensure autonomy and HA for production XI system) will be deployed on Java separated hardware system of Xi production system.
On master SLD all systems are described and all machine are linked with it (SLDAPICUST) except production XI one
On slave SLD, all data of master one are replicated and only XI system is linked with (SLDAPICUST)

Problems in Dialog instance installation for ECC6.0(ABAP+JAVA)
Does anyone can help me what should be a procedure of installing Dialog instance for ECC 6.0 with both ABAP + Java Stacks.
When installing app server do we also choose ABAP and Java or just ABAP. Installation manual does not cover this and when we run the sapinst we have following problem:
<u>The following are the activities that I have done as pre-reqs on the standby on the server that is to host dialog instance</u>
I have mounted the following file systems on ddrsap02. Created the local filesystem /usr/sap/DSP/D00 and NFS mounted the others
/dev/appsaph 5505024 5503856 1% 5 1% /usr/sap/DSP/D00 <b>(is this required or SAPINST should create it itself)</b>

ddrsap12:/usr/sap/trans 2752512 1084932 61% 5107 3% /usr/sap/trans
Then when I run the sapinst from ddrsap02 to install the DI I get the following error

waiting for an answer from gui
Am I missing some pre-reqs or variable definitions?
I was going through the documentation and it says that /sapmnt/DSP/exe should be a local filesystem for a DI on a separate server. Will this create a problem ?
Also they talk about starting sapinst with the variable SAPINST_USE_HOSTNAME set to ddrsap02. I have tried this also
We are also not 100% sure about the settings for parameters:
rdisp/mssserv
rdisp/mssserv_internal
Accorss Devault Instance and Services Instance profile.
When we define it as per installation GUIDE (Abap+Java page 64) we get the popup message in SAPINST:
<b><html>Profile parameter <em>rdisp/msserv_internal</em> is not set for instance DVEBMGS01/DSP on host dprsap01.<p>You have to set the parameter in the default profile and restart the instance.<p>For further information refer to SAP Note 821875.</html></b>
Other errors follow shortly.
Any help would be appreciatedHi ,
are you able to resolve this error :Profile parameter rdisp/msserv_internal is not set for instance DVEBMGS01/DSP on host dprsap01.
You have to set the parameter in the default profile and restart the instance.
For further information refer to SAP Note 821875.</html>
? if yes , pls let me know , I am stuck with same issue while installing dialog instance .
Thanks

SAP ECC 6.0 EHP4 installation with ABAP+JAVA stack
Hi,
I need to install SAP ECC6.0 EHP4 with ABAP+JAVA stack on windiws server 2008 with oracle.
I have read that for this, we need to install ECC 6.0 EHP4 ready and then upgrade to EHP4 using ehpi installer.
I have found the documents seperately for ABAP and JAVA stack and not for ABAP+JAVA.
I need clarifications on these.
1.Do we need to install ABAP and JAVA instances seperately with EHP4 and then upgrade(In that case I have to install both instances on single host)?
2.Should we give seperate <SID> for both instances and create seperate databases?
3.Hard disk requirement for this set up.(We have 150 GB including C drive)
4.Steps to perform after installing ECC6.0 EHP4 ready
5.Please send me the doc. if anyone has
Anyhelp would be highly appreciated.
Regards,
Surya> 1.In the installation document for EHP4 ready for SAP ERP 6.0 ABAP.It is mentioned that this installation contains only basic EHP4 for ERP 6.0 and we need to install additional EHP4 functionality in the SAP ERP 6.0 -EHP4 ready system.
> It states that atleast Support pacakge stack (SPS) 1 of SHP4 needs to be installed.So If I install this stack using EHPi installer in the post installation activities my SAP ERP 6.0 EHP4 will be in place?Please confirm.
Yes..
>
> 2.Can I install SAP SR3 with dual stack and upgaradte it directly to EHP4 at a time?
Yes you can do it.....as SAP still supports dual stack ERP systems to EHP4
>
> Any solutions or suggestions from others also welcome.
Why do u want a dual stack ECC ystem?? any specific requirement???

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 youHi 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

Hello,
i have a BI 7 system - abap+java stack
the java stack is supposed to be configured to work against client 001 in the abap system
apperently this is not the case
usually it is configured from the http://<host>:<port>/nwa ->identity management but i can't login to the java/portal - the login screen is jumping again and again no matter which user name i put
can anyone advise where is the java client in the abap stack (usually 001) is configured?
Regards,
MosheHi,
Yes for default Central Services Installation the java stack will point to 001 client.
Just check the certificate in the key store(in visual admin), this error generally occurs when the certicate gets expired. If it is the case then delete the certificate and create an new one then import the certificate in the abap stack.

How to create Roles in UME (ABAP+JAVA stack)
Hi,
I have created roles earlier on JAVA stack alone. However, this time I am working on JAVA+ABAP stack. When I am trying to create role in UME, I am getting only two tabs:
General Information
Assigned Groups
I am not getting Assinged Actions tab here.How do I assing actions ?
Can any one please help me in creating roles in ABAP+JAVA stack.
That would be a great help!
Regards
FaisalHI Faisal,
When ABAP is the UME, you can only edit users / groups that are J2EE only. Any group that is defined in ABAP is read-only for the Java Server to prevent conflicts (there is no synchronization) and has to be changed in ABAP.
Please take a look at this link, which has a great graphic describing this.
http://help.sap.com/saphelp_nw04s/helpdata/en/7c/36dcd59865b246b993c471199ba37a/content.htm
So, if the Java group was created in ABAP, the ABAP user has to have the ABAP role assigned to him, so that he is in the group on the Java server. make sense? The graphic in the link above really explains it well I think.
If you a new / custom Java group (not in ABAP) then you should be able to assign users to it from the Java server. -
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 AMIt 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]

There are no standard issues in this split. Only thing you need to do is integration testing for scenario like SSO, Bex Reports etc.

License Problem in Abap+java stack
Hello,
I have installed my SAP XI/PI System with ABAP+JAVA Stack.
I have applied SAP license at ABAP Stack using slicense for web as abap+java, so is there any need to apply license again for java stack, because when i am checking in Visual Admin under license node , it is showing license is not installed.
If it is not required then why it is showing in Visual Admin tool that license is not installed. can some one give me guidance on this issue.
Best Regards,
V.SinghHi,
No restart will not make any difference.
You can overlook this. If in the /nslicense screen you see a permanent license, then no need to worry furthur..
Also in the system info page , you will see:
Software Product :Days Until Expiry
Hope this helps.
Kind regards,

Syncronization of ABAP+java stack during the upgrade.
Hi All,
We have successfully upgraded our BWD & BWQ which is ABAP+JAVA stack .
we have followed the process of uninstalling the java stack and removing the j2ee and SDM folder and starting the system for the upgrade.
Tomorrow we are going to start BWP , i found the way to syncronize the upgrade in upgrade manual like starting the SAPjup when upgrade asks for syncronization.
Can any one suggest me the process of starting the SAPjup for sync like already upgrade is running with SAPup and just waiting for SAPjup to sync it's just a norwal way of starting the SAPjup ? or anything.
But i am thinking to go in normal what we followed for the BWD&BWQ.
Please suggest...

Hi,
My sap is running on ecc6.0,linux with maxdb(abap+javastack) we are taking backup through database manager in tape.while restoring it will ask any java files.
ThankuHi
Thanks alot for ur quick response.
If I want to follow SAP System copy(export/import) procedure using sapinst tool , I need to shut it down the SAP instance , which is not possible everyday.
Is there any way out to take backup of ABAP+JAVA stack to tape and restore in another machine using last sucessfull backup using backup/restore procedure(Database Manager).
How can I take backup of ABAP+JAVA stack without shuting down the SAP Instance by using any sap standard tools (sapinst) and can be used to restore in any new machine in case of emergency?
ThankU
