Patching dual stacks ABAP + JAVA simultaneously

Hi,
I would like to know if I can patch ABAP and JAVA on a dual stack system at the same time. According to the patching document I can run an SGEN when the JSPM is running but it does not tell me why I can not patch a dual stack system simultaneously. I have discovered that the JSPM restarts the dispatcher in order to update itself. After this initial step the ABAP stack should remain available providing the kernel has been manually updated.
Does anyone have any advice on this?
Thanks,
James

Hi,
I had a similar case where I had to install a java stack for an already existing CRM system running on Windows/SQL Server.
I installed a different SID for Java on the same host and I installed the Java database as a second database in the same SQL server engine.
Therefore I shared the hardware resources but still had 2 separate stacks as best practice.

Olivier

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.

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

Is it possible to Install Net weaver 7.3 as Dual Stack (ABAP +JAVA+EP+BI)

Hi All,
I am trying to install the NW 7.3 as Abap+Java stack, But I could not find any option to install as dual stack.
If any one Know the solution, please inform to me.
Thank you very much in Advance.
Regards,
Amar.

> But you can install PI, and then deploy all the other SCAs with JSPM.
...and on the first upgrade/EHP installation the system will be hosed because the tools don't support dual stacks.

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

Any advice / guide on how to create separate Stack ABAP + JAVA for CTS+

Hello Experts,
Can you please point me to the how to guide for creation of separate Stacks ABAP + JAVA for CTS+ Transport Management.
Also can you please clarify how I can convert STMS Virtual systems in to Real systems? Any guidance for this?
Thank you

Hello,
You should have a look at the installation guide.
http://service.sap.com/instguides -> SAP Components -> SAP Solution Manager -> Release XXX

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).
Best Regards,
Matt

Restart the Java-Engine in a dual stack installation (java+abap)

Hi,
how is it possible to restart or start only the j2ee-engine in a dual stack installation. We have a JAVA- and a ABAP-Stack and want only restart the JAVA-Stack. In windows i can use the MMC of SAP but how is it possible in UNIX.
regards,
sharam

Hi Eric,
i konw this TR, it doesn't work. There are two possibilities:
restart j2ee-local
restart j2ee-global
we try it with j2ee-local because we use a dual stack installation. What could be the problem. Is there an other possibility? How can i restart the j2ee-engine directly on my unix machine?
regards,
sharam

SSO within an ABAP+JAVA on the same host

Experts:
We have a dual stack (ABAP+JAVA) NW04s on the same host.
The usage type EP7 is enabled.
From this EP7 we want to access its own ITS thru SSO.
We configured the SSO just like we did for the EP7 + ECC on 2 different hosts.
However, we are always asked for an ID/password when trying to test the SSO from the EP7.
The error is:
"SSO logon not possible; browser logon ticket cannot be accepted"
Please advise. Points guaranteed. Thanks!

hi,
I also tried to do the same, but i think it's not possible.
I read somewhere that SAP recommends to use different instances of ABAP and Java. I installed seperate ABAP and Java instances on the same host and then configured SSO using the Configuration Wizard in NWA configuration. and it works perfectly.

Ankur

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

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.

Sriram

SAPINST: install IDES ECC6 EHP4 ABAP+JAVA (Windows 32 - Oracle)

Hi,
I have received the new IDES ECC6 EHP4 DVDs and I nedd to install a ABAP+JAVA instance.
It is not clear which option I have to choose in the SAPINST program.
In the past was present ERP2005 central instance. And now ?
Thank
Andrea

Hi Andrea,
As of SAP ERP 6.0 SR3, you must install an SAP ERP system only on 64-bit operating
systems.
For the dialog instance, you can still use a 32-bit operating system
As of SAP enhancement package 4 for SAP ERP 6.0, you can no longer install SAP
ERP dual stack (ABAP+Java) systems. If you want to use both SAP ERP ABAP and
Java Components in your system landscape, you have to proceed as follows:
1. Install a separate SAP ERP ABAP system.
2. Install a separate SAP ERP Java system.
3. Configure the connection of the SAP ERP Java system to the SAP ERP ABAP
back-end system
Hope this clarifies your concern!!!

Change IP address on ECC6 (ABAP + JAVA stack)

Hi all,
we need to change the IP address of our server running an ECC6 with double stack (ABAP & Java). Also the DB is in the same server (it's a Demo IDES system).
The computer's name will remain the same as previously.
In the HOSTS file we have updated the new IP address.
Are there some other manual corrections needed ?
Is ther something to be adapted in the J2EE admin of config ?
Thanks in advance.
Andrea

Hi,
I have looked into OSS note:
Note 757692 - Changing the hostname for J2EE Engine 6.407.0 installation
It is mainly related to host name than IP address.

Delete JAVA Stack in system with ABAP+JAVA

Hello,
A few days ago I installed a SAP ERP 6.0 SR3 with both stack: ABAP+JAVA.
But now due some things, I want to know if it is possible to delete the JAVA stack! Yesterday I did a search how to do this, how it is possible to do this, and I found a document/presentation "SAP NetWeaver 7.0 - Deinstalling Java Add-In" on the following link:
http://www.sdn.sap.com/irj/scn/index?rid=/library/uuid/608b079f-d0f2-2c10-62ac-a00f1b6d536f
The database of this system is a MS SQL Server 2008 (R2) and the operation system a Windows Server 2008... and as you can read in this document, it is more focused on Oracle databases, so I would ask you if this document is correct (it is official?) and if it is possible to do this in SQL Server environment, and if you know which are the manuals post installation activities for SQL Server, because all that manual post installation steps in this document is for Oracle DB!
Thank you in advance.
Kind regards,
Joao Dimas - Portugal

Hello Subhash.Chandra
I did the deinstallation of SAP Java Add-In, for this I followed that document which I described above. After deinstallation through sapinst, I also eliminated some directories as it is mentioned in that document, like the following directories:
DIR_GLOBAL\security\data
DIR_INSTANCE\SDM
DIR_INSTANCE\j2ee
I also delete all Java parameters in default and instance profile (like j2ee*).
So, after all, I started the ABAP instance... the system was starts, but I unfortunately the SAP MMC console show a yellow semaphore which is related with a problem disp+work.EXE, it have the following status:
Running, Message Server connection ok, Dialog Queue time: 0.00 sec, J2EE status info unavailable.
I already restarted the sap system but even so that error is shown!
I checked the dev_disp:
