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).

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.

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?

Is SAP PO 7.4 dual stack installation??

HI experts,
Could anyone let me know if SAP PO 7.4 is a dual stack installation or can we go for single stack as well.
As PI 7.4 is based on HANA , so while working on it shall we use ICO or old classic configuration. Shall we go for java based adapters(eg IDOC_AAE/HTTP_AAE) or old abap based adapter..
Thanks,

To add few cents - May be your basis guys just read the title
Support for Dual-Stack discontinued in SAP NetWeaver 7.4 in general with exceptions
SAP NetWeaver 7.4 is positioned as the follow-up on-premise release for SAP NetWeaver 7.31.
SAP NetWeaver is among other things optimized for SAP HANA as the foundation for the SAP Business
Suite on SAP HANA project. This means that dual-stack deployments and implementations are not
supported any longer. The only exception to this rule is SAP NetWeaver Process Integration on a traditional
database system, which still requires a dual-stack implementation. However, note that a single-stack SAP
NetWeaver Process Integration Java exists that offers 95% of the features of classical dual-stack
implementations. Therefore, customers should investigate whether an existing SA

Removing J2EE stack from dual-stack installation

Hello.
Does anyone know if it's possible to remove the JAVA-stack from a ERP6.0 dual-stack installation ?
We have a ERP 6.0 system running HCM services. The ERP system is installed as dual-stack, but the JAVA-stack is not in use as we also installed a separate NW 7.0 JAVA system hosting portal and java hcm services.
Thank you.
Gerhard.

Hi,
Yes, you can drop Java part from existing dual stack system.
1) Stop cenrtal service instance and all dialog instances of your system.
2) Also, stop J2ee engine of CI from SMICM.
3) Hash out all Java parameters in your default and instance profile (like j2ee, exe/j2ee, exe/jlaunch, jstartup etc.)
4) Delete central service instance.
5) Delete Database schema
6) Delete directories (/usr/sap/<SAPSID>/DVEBMGS<xx>/SDM and /usr/sap/<SAPSID>/DVEBMGS<xx>/j2ee)
Thanks

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?

Looking for orig OS 9.2.2 installer for dual 1.25 G$

Hi,
I'm helping a friend with a dual 1.25 G4 (not FW800) and I cannot find an original installer CD for 9.2.2 that came with the computer. A generic 9.2.2 installer won't work because of a boot prom issue. If you have this cd and would be willing to dupe it and mail it to me, please email me at wrussel1-at-twcny.rr.com
Thanks in advance!
15" 2.16 macBook Pro/2gRAM Mac OS X (10.4.6)

Hi, William -
A generic 9.2.2 installer won't work...
Correct - there is none for OS 9.2.2. The last retail OS 9 Install CD is for OS 9.2.1.
...I cannot find an original installer CD for 9.2.2 that came with the computer.
There is none. The installer for OS 9.2.2 for all G4 MDD models is part of the combo disk set that came with the machine - that set boots to OSX, but has an option to install just Classic (OS 9).
One or more of these Apple KBase articles should help in using that disk set to install OS 9.2.2 (Classic) -
Article #106294 - Mac OS X: How to reinstall Mac OS 9
Article #107383 - Mac OS X 10.2, 10.3: How to perform Mac OS 9 clean installation with Restore CDs
Article #42929 - Using Restore Discs with Mac OS X 10.2 through 10.3..3
If that disk set is also missing, about the only reliable source is Apple's Customer Service - they often have replacement disks available for reasonably recent machines.
http://www.apple.com/contact/phone_contacts.html
EBay is another possibility, but be cautious - the buyer does not always receive what was sold.

SSO Configuration : Dual Stack Installation with same SID

Dear SDN users
We upgraded our BW system to 2004s with Java add-in installation. We used same SID for ABAP and Java stacks. I could not find a good document to configure SSO between ABAP and JAVA with same SID installation. I would appreciate if you can provide a link to the document or give me sequence of steps to be executed.
I am aware of note 917950 and 888687.
Thanks in Advance
V Reddy

Chetan
We are done with upgrade. Currently we are using SSO with UIDPW. I would like to configure SSO using certificates..
If I remember correctly instguides suggest to run template installer. I did use template installer but it fails in some steps as we have same SID for ABAP and Java. I manually configured all the steps using instructions from " SAP Nw2004s BEx WEb System Landscapes" published by Tobias Kaugmann. Still no luck.

Java Stack Vs Dual Stack in Pi 7.3

Hi experts.
I open this thread because I'd like to know your opinion about the newJava installation option in SAP PI 7.3. In previous realeses (7.0,7.1) I felt more comfortable and safe in abap stack and I'm a little afraid about working only with java stack.
I'd like to know advantages and disadvantages to choose java stack instead of dual stack, why you'd choose one of two options or both in your nexts customers.
Thank u so much and happy new year!!!!

Java Stack or Dual Stack in 7.3
Java Stack alone: Almost all standard adapters including HTTP, IDOC and Proxy are all available in this stack. you need to use Integrated Configuration object for this. You are basically going to use Advance Adapter engine alone for the entire processing.
Pros:
No persistance steps here. So you would improve performance many folds for sure.
Throughput is also improved very much.
since 7.3, Solution Manager is available for monitoring inaddition to RWB and NWA. So monitoring would not be issue.
If you are looking for real performance improvement, Single stack Java to go.
Cons:
Abap mapping is not supported.
Message split to multiple receivers are not completely supported.
BPM interfaces are not seamless migration here. SAP 7.1 and lower versions support BPEL wheras 7.3 supports BPMN standards. So you might have to tweak a bit to modify existing interfaces here
Dual Stack:
Your option is pretty open. If you need some specific interfaces to handle only java stack, still that is possible and increase the performance. Also if you have lot of existing interfaces that requires BPM interfaces, ABAP mapping , Multiple split /branching etc.
still dual stack is the better option now. Here developer decides according to the requirement.
Still safe mode is going for Dual Stack for now and change in the future to single java stack alone.

Urgent: How to do the Silent Installation for J2RE v1.4.1

Hi guyz,
Can anyone tell me How to perform Silent Installation of J2RE v 1.4.1.
I checked out with J2RE V 1.4.2 which supports Silent mode installation but not JRE 1.4.1
thanks in advance,
Saurabh Bhatnagar

Hi People,
Just found out a site which has information on Silent Installation of JRE 1.4.1 ... but its not a straight fwd one. You need to run the installer atleat once to create a response file which will ecord your actions and you can use it in later installs for a silent installation.
The article says about Slent installation in JRE 1.3 but I just check it ... and it works perfectly with JRE 1.4.1 also.
Here's the link

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

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.
Regards,
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

PI system upgrade from 7.1 to 7.4 dual stack

Hi,
We want to upgrade PI system to 7.4 .currently we are using PI 7.1 system (dual stack)and want to go for 7.4 dual stack.
which one single stack or dual stack is the best approach and what are the impacts normally see when upgrading to newer version.
We are planning to install 7.4 freshly recomonded by SAP .
We need to migrate objects from older system to newer system?
I want to know the process from basis perspective also .
Import/export or migrate is the best way to move objects from older sytem to newer system.
Please suggest me any links about the process including basis point of view also suggestions for the approach.
thanks,
aman

>>>> which one single stack or dual stack is the best approach and what are the impacts normally see when upgrading to newer version.
I would prefer single stack considering the SAP's future road map but of course it depends on how much effort your company is ready to spend. Incase you have lot of CCBPM's then you'll have to redesign them using Netweaver BPM if you go with single stack.
As are going with fresh installation(migration) of dual stack then you don't need to invest much.
>>> We are planning to install 7.4 freshly recomonded by SAP .
We need to migrate objects from older system to newer system?
I want to know the process from basis perspective also .
There is wizard using which you can move the directory objects ( classical scenario's to Integrated configurations). Please use it for ID objects
Refer to the below blog for more details. (ignore blog's title. it's applicable for dual stack-> dual stack too)
Moving Integration Directory Artifacts from dual stack to single stack
For ESR you can simply export and import the tpz file.

They can simply follow the installation guide and execute the post installation steps properly.

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 :
...to our client, we adviced Dual Stack installation...
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?
