Restore ABAP side of dual stack

Hi
Been 4 years + since I did any work on I-series. After patch of BW 7.01 ABAP side SPS6 to 16 using SPAM I tried to use JSPM to patch Java side.
System didn't allow this after patching JSPM to level 16 so was forced to use SUM. Note 1881524 suggests you can't update java side separately so need to start again. Kernel was updated to 7.20 from 7.01 after patching ABAP side.
Is it sufficient to restore r3sidDATA library and then continue with SUM ?
I'm also currently converting to new user concept per note 1149318 as a pre-req to using SUM.
Advise appreciated.
Regards
Dave

Hi Dave,
According to note 1149318, you could try to update the ABAP stack to a next available patch level
together with JAVA. And this can avoid the restore. If you just want to keep ABAP at 16, you have
to do the restore.
It is enough to restore R3<SID>DATA library, and please delete all the sql packages after that.
About SUM, please make sure you have switched to new user concept and 720 kernel before start
it.

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.

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 7.30 dual stack - different time in rwb, pimon and ABAP stack

Hi @all,
I am working with the client on a PI 7.30 dual stack system.
During monitoring of message processing I saw that there are differences in the time displayed while monitoring the processing of identical messages
e.g. channelmonitor (mdt/channelmonitorservlet and rwb) is 1 hour behind pimon
The time displayed in the ABAP Stack (Menu System - Status) differs also 2 hours ahead of pimon.
Are there java parameters to configure the used time zone and which could be reason for this behaviour.
For me it seems strange that there is a difference between to tools (channelmonitor and pimon) I was supposing are based on the same technical stack
Would be nice to have the same time throughout the whole system.
Any help appreciated.
Best regards
Jochen

Hi Jochen,
I did not found the option to change the time zone for pimon. Please refer the below wiki it might helpful

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

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

Pl. make sure SLD for the Java stacks are defined correctly.

Enqueue server and Message server in ABAP/Java dual stack

Hi you guys,
I have some questions when studying SAP, could you please explain for me:
- In ABAP and Java system, do each stack have it own enqueue server and message server?
- What is the difference between Enqueue server and enqueue work process in ABAP stack?
- If there is one message server for each stack, which messager server (ABAP or Java) will the Web dispatcher connect directly to?
- How do ABAP message server and Java message server communicate with each other?
Thank you very much.

1. in Dual Stack, normally you have ABAP Stack and SCS Central service Instance. ABAP Instance has Message server, SCS has it own Message server and enqueue server. ABAP instance doesn't have enqueue server, because the SCS already has enqueue service
2. Communication between ABAP and J2EE Engine uses RFC (JCo) or HTTP Interface.
Web Dispatcher will connect to the ICM of that instance, and the ICM is talking to Abap dispatcher and J2EE Dispatcher.
3. The term: enqueue server and enqueue work process , already shows its different quite obviously.
What so confuse about it ? do some search on SAP Online Documentation.

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.

How to separate ABAP+JAVA Dual stack in stand alone engins?

Hello SDN!
We are thinking about to separate our Dual Stack ERP 6.00 System on Windows/Oracle in two stand alone system Java und ABAP. Wie have afew small implementation in Dual Stack such as ESS and wie have no modifications at all.
Has somebody an expiearence with that? Knows somebody about some tools for such an action?
I will be very pleased for any help

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).

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?

Migrate dual stack to ABAP only

We have a dual-stack NW700.
We only want to export its ABAP portion and then use the export to build a new NW700 ABAP only.
1) is this feasible (i.e. the traget system will run? It's OK run without JAVA functionality as long as it runs)
2) if so, on sapinst , should select "system copy-> oracle->central system->system based on ABAP"
OR
"system copy-> oracle->central system->system based on ABAP + JAVA" ?
Thanks!

Hi Jessica,
You don't have to export the database.. Removing the java schema from the database is sufficient.
The installation guide explains how to remove a java add-in from a dual stack system.
Basically you do a drop user cascade from the java schema, remove the java software and delete the java specific parameters from the instance profile.
Kind regards,
Mark

Splitting System Copy on BI Dual stack

Hi,
We are planning to split Our BI Dual stack system.
1) To perform ABAP system copy through Oracle tools.
2) To perform Java system copy through Sapinst and them import in to the system copy performed in step 1.
Could some one help me out, can we go ahead or not.

Hi,
> We are planning to split Our BI Dual stack system.
> 1) To perform ABAP system copy through Oracle tools.
If you use backup/restore method to build your ABAP system then you should know that Java Schema is also present in the database, so, after restore you need to drop Java schema as well or you can do this before restoring the system in source system then take backup and restore this backup on target system.
> 2) To perform Java system copy through Sapinst and them import in to the system copy performed in step 1.
>
Yes, you can do that. But I really doubt to use this method to build your production system. I would recommend following approach:
1) Install new As Java system with different <SID>.
2) Migrate all existing functionality of your existing As Java system to new As Java system. Do all the testing to check all the scenarios.
3) Drop As Java from your dual stack system.
Also, check below threads:

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 7.31 Dual Stack SSL configuration

HI Gurus,
I have a quick query, I am configuring SSL on my PI 7.31 systems.
I have checked all the standard guides and forums but I have one doubt.
Q1 - Is it necessary to configure SSL both in ABAP and JAVA side ?
Q2 - If I just configure SSL in STRUSTSSO2 in ABAP , will it be more than enough ?
Q3 - In what cases do we need to configure SSL in JAVA side ? And does configuring SSL in JAVA mandatory require sapcryptolib files ?
Please share your views.
Cheers, SG

I want to understand is it necessary to configure SSL in both ABAP and JAVA in case of dual stack PI ?
>>> Please refer to Huseyin's comments in the below thread..
PI 7.3 Dual Stack SSL configuration
In what cases do we use JAVA SSL in Dual stack system ?
>>> AFAIK - when you use http_aae adapter/soap with https then you should configure the SSL on java stack.

How to update dual stack kernel

hi all,
all we know sap support dual stack in slm and PI.
I had a slm71sr1 install with swpm/jvm use kernel 402 in win2008.
I want to update kernel to ver600.
the abap stack can logon after the update.
but mmc show the java can't startup.
I'd try to run sapcpe
sapcpe pf=<drive>:\usr\sap\<SAPSID>\sys\profile\<instance profile> list:<drive>:\usr\sap\<SAPSID>\sys\exe\<uc|nuc>\<platform>\j2eeinst.lst
and
sapcpe pf=<drive>:\usr\sap\<SAPSID>\sys\profile\<instance profile> source:<sapjvm directory> list:<sapjvm directory>\sapjvm_<version>.lst
but the java instance still can't startup and i had to restore the old kernel.
any one had some idea for dual stack update kernel?
Thanks.
B&B

Hi bbs,
You need to run the command
1.sapcpe pf=<drive>:\usr\sap\<SAPSID>\sys\profile\<instance profile for DVEBGS<xx>
2. sapcpe pf=<drive>:\usr\sap\<SAPSID>\sys\profile\<instance profile SCS<xx> >
Then start the system and let us know the result and also paste the dev_server0 logs as well.
