NWDS for PI 7.4 Dual stack

Dear All
I am on SAP PI 7.4 dual stack which NWDS version should i use because i tried with both NWDS 7.3 and NWDS 7.31 also
NWDS 7.3 its not connecting at all it says improper configuration
NWDS 7.31 connected to ESR and but ID it says only for single stack.
Can you please help
Regards
Sandeep

Hi,
There is no dedicated NWDS 7.40, the NWDS 7.31 is also to be used for NW 7.40 (see also the note 1791485).
For NW server 7.40 SP<X> one has to use NWDS 7.31 SP<X+5>.

LDAP configuration for HR Portal in dual stack EHP4 - Best Practice

Hi Experts,
Hello Experts,
We are trying to use the JAVA Stack of ECC server for HR Portal i.e Dual Stack and have applied EHP4 package for ESS/MSS Appraisal. When we are trying to configure the LDAP ADS datasource through portal , we are not able to do it since ABAP datasorce file is available by default.This we are doing for HR(ESS/MSS) Portal.This is for access to the object data stored in the Active Directory.
We have already checked note 718383.
Also, for the scenatrio ,LDAP <-> ABAP <-> J2EE
We have already checked sap help doc.here:
http://help.sap.com/erp2005_ehp_04/helpdata/EN/e6/0bfa3823e5d841e10000000a11402f/frameset.htm
What should now be the best practice to follow for configuration ? Should we go for separate Portal server or is it possible to use Java Stack of ECC server for configuration ?
Also, LDAP <-> ABAP <-> J2EE scenario please suggest if it a best practice and we can follow the same .What are the limitations , risks and issues ? Please suggest if this has been implemented and running well in any live project .
Are the suggestions applicable for load balanced production servers as well?
Thanks,
Rakesh

Hi,
the UME datasource must remain ABAP but you can sync the users between ABAP and LDAP using the LDAP connector:

Single stack vs. Dual Stack - Why does SAP recommend single stack?

Hello SAP,
I am a business partner who specializes in infrastructure consulting for SAP solutions. The SAP Consultants I am working with recently have been recommending that customers install single stack systems. I would like to know why? Are there problems with dual stack systems? Is SAP changing things in a later release and they want customers to be prepared for the change?
From an infrastucture point of view this recommendation combined with SAP NetWeaver architecture will result in an explosion of SID names which leads to an explosion of application server instances and DBMS instances and an explosion of installed servers. I know it is possible to combine SIDs into a single DBMS using MCOD and to have multiple application servers in a single physical server, but there are issues with mulitple application server instances and MCOD use which make normal maintenance operations difficult.
I think it would be much better for customers to install dual stack systems and simply adjust the SAP profile parameters to disable one stack or the other. This way, you could still have 1 stack per application server instance and you would not be have to be creative with SAP SID names!!! Creating a DBMS instance or installing an additional server is not a simple nor economical proposition.

Zaz

I am a business partner who specializes in infrastructure consulting for SAP solutions. The SAP Consultants I am working with recently have been recommending that customers install single stack systems. I would like to know why? Are there problems with dual stack systems?
The problems are:
- difficult to size and maintain - Java + ABAP will fight for resources (memory,CPU) and there´s not much one can do to tune if either ABAP or Java as dual stack instance on a single box is running nuts (for whatever reason).
- System copies via R3load - if you want to copy a huge system (let´s say ERP 6.0 + Java stack) you need to use sapinst + R3load to do the copy. Imagine if the system is 1 TB or bigger, this is very time consuming
- Upgrades are complicated - if you upgrade a dual stack system you need to run two PREPARES and two upgrades at the same time - there are sync points each upgrade wait for the other to finish --> difficult to plan in sense of runtimes and even more notes/preparation to do (a dual stack SolMan upgrade from 3.2 to 4.0 had almost 100 notes (technical!) and two upgrade preparation guides...)
- interdependencies - example: you run ERP + EP + BI-Java on one system. You upgrade your BI (which is on a different box) to a new support package. Since the BI-Java need to be in sync with the BI ABAP support package you need to upgrade the EP too - and since there´s a direct dependency (doublestack system) you will need to install support packages on your ERP. So you finally end up in having dependency chains that a total different system (BI) will force you to upgrade/patch your ERP. And if you have e. g. a CRM connected to the same EP you will need to patch that too...
Is SAP changing things in a later release and they want customers to be prepared for the change?
No - the possibility of having a dual stack installation will be still there.
From an infrastucture point of view this recommendation combined with SAP NetWeaver architecture will result in an explosion of SID names which leads to an explosion of application server instances and DBMS instances and an explosion of installed servers. I know it is possible to combine SIDs into a single DBMS using MCOD and to have multiple application servers in a single physical server, but there are issues with mulitple application server instances and MCOD use which make normal maintenance operations difficult.
I agree - MCOD is not a good solution for this problem.
I think it would be much better for customers to install dual stack systems and simply adjust the SAP profile parameters to disable one stack or the other. This way, you could still have 1 stack per application server instance and you would not be have to be creative with SAP SID names!!! Creating a DBMS instance or installing an additional server is not a simple nor economical proposition.
There are 36 * 36 * 36 (minus a few reserved) names for SIDs- this should be enough - also for the biggest customers
Of course one could install both and disable the one you don´t need - but this won´t help in dependency thing. If you e. g. install a dual stack instance for CRM and disable the Java part, you can nicely run it. In case of an upgrade, you will need to upgrade the Java part too (see above) although you don´t use it. The upgrade will detect the doublestack and wait for the java instance to be upgraded too. Same is true vice versa. And believe me: you don´t want that
In fact it is better to separate - that´s at least our experience. The main no-go for such a configuration on our side was the dependency thing. Since they are there and you can´t do much about them we decided to have a 1:1 relationship for ABAP backend and Java "frontend". You will get more instances (and names and databases) but you can patch applications independently from each other. So an implementation of a BI patch won´t imply that you finally also patch your ERP production and other systems that connect to that portal.
There are virtualization techniques available to not need more boxes, you can consolidate them on one machine as if you were installing a dual stack so that is not really an issue. This depends, of course, on the platform and database you use (e. g. Oracle does not support production installations in VMWare). We use for our Java instances Solaris on Opteron (or Intel 64bit) and zones/containers and for the ABAP part we use Linux + Xen. Both virtualization methods come with the OS (so no additional $$$) and both are supported by SAP.
The propagated advantage of having a dual stack installation (shared memory access etc.) is so small that it doesn´t outban the additional complexity - which is definitely there.
I hope those arguments will help to understand SAPs (and the consultants) position - get back if you want more

Development Scope through NWDS on 7.31 Dual Stack

Per my understanding NWDS can be used for developing ESR and ID components but only if we have installed the usage type PO.
We have dual stack PI 7.31. What is the scope of PI objects development through NWDS in this case other than usual JAVA coding...adapter module development, dirapi devlopment ..etc..
Thanks

Hi Ashish,
you can use ESR development in NWDS with dual stack, but can not perform the ID development.

ChaRM for Dual Stack ABAP & JAVA - No http port for system SPD

Hi,
I have configured the CHARM for Dual stack ( Java, ABAP). when I perform the action 'Logon to System' it gives me following option
" The system is a dual stack system. You can log
on to the ABAP stack or non-ABAP stack
To which stack do you want to log on?
ABAP or Non ABAP"
If I click on Non ABAP, one more message comes
"You can logon to system SPD or just display its
transport requests
What do you want to run?
Requests Or Logon"
If I click on Logon I get the Information " No http port for system SPD "
& If I click Continue It will take me to Ugent Correction & error appears as 'Action System Logon in system SPD 100 of type Source Systems has been cancelled'
How to Solve this error.
Regards
PK
Edited by: PK on Sep 1, 2010 5:59 AM

Its possible to login to portals(non-ABAP systems).
Please check.

NW2004s: SPS installation for dual-Stack-Installation (Java/ABAP) - PI(XI)

Hello,
we want to apply a new SP stack to a NW2004s (ECC 6.0) - dual stack (Java/ABAP) with PI(XI).
The ABAP stack is sucessfully patched yet,
but the Java stack needs still to be patched!
In the SPS guide for SPS 9 and some OSS notes you can read that during the patching of the Java stack, the whole system (ABAP and Java engine) are restarted several times. But the JSPM should ask you before the restart.
Do you have experiences how long the patching of the Java stack will take (downtime)?
How often needs the system to be restarted?
Is it possible to work with the ABAP engine (ABAP development, etc.) during the installation of the Java SPS with JSPM until the system needs to be restarted?
How is it possible to minimize the downtime of the system during the Java SPS installation?
Thanks in advance!
Best regards,
Stephan

Hi Stephan,
"Do you have experiences how long the patching of the Java stack will take (downtime)?"
I believe this is most highly dependent on the hardware. Although some patches will deploy more objects than others, the deploy time is shorter on better/faster hardware. I applied SP9 on my laptop PC (java only, no ABAP stack) and it took a few hours total -- including my processing and error correcting time. My laptop has only 2 GB RAM so this process was greatly slowed by the amount of available memory (I was running other applications, like Outlook, etc.) resulting in a lot of disk swapping.
"How often needs the system to be restarted?"
Again, I have a java only installation, no ABAP, but I believe there was only 1-2 system restarts. The system had to be restarted after the application of the java kernel part of the patch, then shutdown and restarted again for the offline deployment phase. I cannot remember if there was a restart after the online deployment phase.
"Is it possible to work with the ABAP engine (ABAP development, etc.) during the installation of the Java SPS with JSPM until the system needs to be restarted?"
Yes.
"How is it possible to minimize the downtime of the system during the Java SPS installation?"
I think the best way is to have the best hardware! Also, be sure to be thoroughly prepared by reading the guide, all of the Notes, etc. I was slowed by a previously correctable error (my administrator password had been previously changed and I had not changed it in the secure store -- Note 701654).

PI 7.4 dual stack

Dear experts,
I understood PI 7.4 SP06 can be installed on dual stack ABAP+Java. If this is the case, what about ccBPM/BPM scenarios ? can support both ? only nwBPM/ccBPM ?
what about NWDS present version ?
Deva

Hi Deva,
In case there you are making use of Dual stack PI you CCBPM scenarios will work same as earlier dual stack PI versions. In case of Dual stack it will still be PI and not PO as PO comprises of Lone Java PI+ N/W BPM+ BRM on one system.
Also if you want to make use of N/W BPM it has to be installed seperately. Ideally you should go for lone Java if you want to make use of N/W BPM to minimise your hardware requirements.
Also NWDS version has to be less than or equal to the PI version being used.

Predicates for XPath in Condition Editor of NWDS for PI AEX 7.4 (SP 7)

Dear all,
we are in the middle of migrating from our old Dual Stack PI 7.0 to our new PI 7.4 AEX.
We have a fairly largen receiver determination on the old system that makes heavy use of predictes. One expression for example looks like this
(SHPMNT05/IDOC/E1EDT20/E1EDL20/E1EDL37/E1EDL49/E1EDL50[XSIQUALF='EEIVERF']/VLABDATA = 01)
However, when I'm trying to insert this in NWDS' condition editor there's an error stating "Predicates are only allowed with EXISTS operator"
1. Is this a limitation of the condition editor in NWDS?
2. Is there a way to configure the above XPath so it is working in NWDS?
3. Would it be safe / wise to configure the mappig in ICO in Swing Tool or would this be overwritten by NWDS configuraiton?
Many thanks
Jens

Hi Jens
From SAP library, the example shows that the usage of predicate is with the EX operator, so maybe it is a limitation.
Integration Directory - SAP Library
Maybe you can try to combine your two conditions in the predicate and use it with the EX operator
(SHPMNT05/IDOC/E1EDT20/E1EDL20/E1EDL37/E1EDL49/E1EDL50[XSIQUALF='EEIVERF' and VLABDATA = '01'] EX)

Dual Stack NW 7.0 installation with R/3 Backend as UME

I have a quick question guys. I am about to install a dual stack NW system with ADS(SQL server database on windows) and will use a R/3 Enterprise running on unix as the UME datasource. Now this R/3 enterprise backend already acts as bakend for Portal system and uses sap logon tickets and as such already has the user SAPJSF. Now when i actually perform the NW 7.0 installation and enter a master password during the course, would this override the SAPJSF user in R/3 backend system at all.
What are the general problems that are caused with using an existing ABAP only system as the UME for your Java stack(Dual stack actually) systems. Can you advise.
Regards
Kalyan

Hi,
Now when i actually perform the NW 7.0 installation and enter a master password during the course,
would this override the SAPJSF user in R/3 backend system at all.
NO....Not at all..
SAPJSF user is used for the communication between ABAP and JAVA stacks. SAPJSF user is an independent user of each independent ABAP stack.
ABAP data/user-store is the place where the users, roles and authorizations of an ABAP System are stored.
And with the same concept, the UME is the same mechanism for users, roles, permissions of an JAVA system.
After installation of your new NW ABAP+JAVA Stack, you will have to specify the SAPJSF user of ur old R/3 ABAP system which you want to use as User Data Store for ur Newly installed Java System's UME.
In ABAP System section u will have to provide all details of ur SAP R/3 application server, which ur portal is already using as User Data Store.
What are the general problems that are caused with using an existing ABAP only system
as the UME for your Java stack(Dual stack actually) systems. Can you advise.
It depends on the usage of your new application server.

Question about the number of ERS instances in a dual-stack MCS environment

Hello to the group.
I have a simple question for those running a NetWeaver 7.0 (i.e. 2004s) dual stack (ABAP/JAVA) setup in an MCS environment. On each individual node, do you have two separate ERS processes running on the node (as seen in Task Manager) that is opposite to the system running the ASCS/SCS instances? If so, do you have a set of profiles for each of these ERS processes (I am guessing that is true)?
Thanks in advance for your help.
J. Haynes

Has anyone found a good description of the process that runs after one node fails over to another one? help.sap.com mentions that the ASCS will restart and run the command enstatus.cmd but I cannot find what is supposed to happen after that. Is the ERS service itself stopped?
Thanks
J. Haynes

EHP4 Dual stack

hi guys,
we plan to upgrade Enterprise Dual stack(ABAP+JAVA) System to EHP4 system.
In EHP4 upgrade document it says, No dual stack supported for EHP4 installation..was that mean
only for Installation or upgrade too.
Seperate SID is required for EHP4 system after upgrade? Please confirm.
thanks

hi jaichan,
yes, you are right ..For new installation of SAP ERP to EHP4 level, you cannot install dual stack system..i have read in sap note 855534..please find below the extract from this note:
As of SAP Business Suite 7, you can no longer install Dual Stack Application Systems (ABAP+Java).
If you want to use both SAP Business Suite ABAP and Java Components in your system landscape, you have to proceed as follows:
1. Install a separate ABAP-based SAP Business Suite system.
2. Install the required Java components in a separate Java-based SAP system.
3. Configure the connection of the Java-based SAP system to the ABAP-based SAP Business Suite back-end system.
The SAP Business Suite 7 comprises: EHP4 for SAP ERP 6.0, SAP CRM 7.0, SAP SCM 7.0, SAP PLM 7.0, SAP SRM 7.0
As of now you will find the latest recommendations at a central place in SDN:
https://www.sdn.sap.com/irj/sdn/landscapedesign -> Distribution Models
You will also find information about the deployment of SAP NetWeaver usage types and the SAP Business Suite there.
but you can upgrade your previously installed SAP ERP dual stack system without having seperate SID's thing...
We have upgraded around 50 of our systems without any problem
thanks sunny

Issue while creating Component Based Message Alerting in PI 7.31 Dual Stack

How to restart Java Engine in ABAP+JAVA dual stack installation ?

Dear Experts
if i use stopsap r3 in this dual stack installation - it stops both ABAP & JAVA Web Application Servers.
I want to restart only JAVA Weba pplication server.
How do it ?
Thaks in Advance !
Rgds

But theoritically they are 2 indpeendent installations like
AS ABAP
AS JAVA
..Do you aggree ?? really am not good on basics!!
During the installation also - if select AS ABAP & AS JAVA - it will become dual installation
and it does not show
any dependency while installing that AS JAVA requires AS ABAP.[Installation Component Selection and Dependency Screen shot|http://i303.photobucket.com/albums/nn153/S0002919350/SAP%20Issues/Oracle_Patches.jpg]
Installation Component Selection and Dependency Screen shot
Is it because if AS ABAP is down - AS JAVA UME is 001 client - and Java authentication fails ?
Can we de attatch from ABAP UME for my requirement like - running JAVA WAS alone w/o ABAP.

PI 7.31 Dual Stack Using BPM/BRM and ccBPM

Hello,
My client has decided to use SAP PI 7.31, because we have many ccBPM solutions, being used a long time, the idea is install the Dual Stack solution and keep using the ccBPM, at least for while.
But for the new integration solutions, we would like to use the AEX(Local AEX-Based) and connect to BPM and BRM, and maybe migrate the old solutions when possible.
Is it possible, use the both solutions( AEX/BPM/BRM and ccBPM) ? In this case, we will have all the benefits and great perfomance
when using the AEX/BPM/BRM(Local AEX-Based) solution, that we have in the single stack ?
Best regards,
Dylon.

Hi, vishal jain.
Thank you! Checking your link, we will probably choose the third case:
If PI is installed as dual-stack, then PO, PI and BPM/BRM, will have to be installed with different SIDs. PI on one SID and BPM/BRM on a different SID.
But the question remains... in this case is possible to use ccBPM and BPM/BRM, ok ?
And when using the BPM/BRPM, how is the performance and benefits ?
Are the same when using single stack solution ?
Best regards!
