Multiple PI Production Systems in Landscape

Hi,
Our SAP PI system is growing larger and larger with more critical interfaces being deployed. Maintaining the system is becoming a pain because if a restart is required we need to inform so may external entities.
A solution we have proposed is to have 2 PI Production servers with interfaces spread across both systems. So if a restart is required on one system then the other system can remain on the air.
Is this possible? And what is peoples views on doing something like this?
Thanks
Gareth

Hi Raj,
maybe we are running in the same issue like Gareth, in the future.
Question: What exactly you mean maintenance became difficult?
What means, you will have so many important Interfaces running during the whole day every minute, you aren't able to find any suittable maintenance window. From business you don't get maintenance window not longer as 15 min. and this is much to short for maintenance work around the whole SAP PI infrastructure (Support Packages, Database, Hardware, ...).
The original question is, how you are able to handle this maintenance scenario?
This is not an HA issue and a second application server is as well not an solution.
Many thanks in advance!
Regards,
Jochen

Track Connections to support Multiple QA & Production Runtime Systems

Hi,
I've read the SAP Help and various other threads in this forum that describe how to configure track connections that will support deployment into multiple production runtime systems. Can the track design therefore support the following scenario :-
Dev --> Consolidation ---> Multiple Pre-Production Runtime Systems --> Multiple Production Runtime Systems.
If this scenario can be implemented in the NWDI Landscape Configurator what would be the best approach to define this ?.
The reason I'm asking is our customer is planning multiple Portals in Production & Pre-Production due to the number of LDAP's currently being used to roll-out to the full user community.
Regards,
Brian.

Hi Kiran,
May be this thread will come in handy. I explained clearly the procedure to deploy to multiple systems
transport to mulitple systems
thanks

Changing Solution manager landscape and having a Virtual production system

We have a 2 line landscape like this
Line1: DEV1 - QAS1 - PROD1
Line2: DEV2 - QAS2 - VirtualPROD.
During our golive pahse the QAS1 in Line1 will be replaced by the QAS2 in Line2 and Lin 2 will be on hold for a while.
My questions,
1) does any one have any experience in topic?, on how to change the system landscape without closing any tasklist/maintenance cycle or project.
2) We have some problems with logging on to QAS system from the change request when having a virtual production system, it works fine from the tasklist.
Unfortunalty we can't see anything in the log.
3)When having multiple QAS systems in one Line , how can the import the change to the second QAS system be handled when using urgent correction since only one QAS is in the task list the one which feeds the production system. (Urgent correction always uses the shortest path to production)
Comments, references and all else is valuable.

Question #2
Apperently does the system check for a connection to the production system and since it's virtual there is no rfc , so would it be possible to create an rfc to a virtual system?

Allowing Multiple Login of users in Production system

Hello,
In my office there are total 4 employes which all use SAP but they all use one username and password so it isn't possible for them to work at same time. Only one employe can work, then after he completes his task he must log-off, and then other employe logs-in and so on... So Multiple Logon option is disabled. I would like to enable Multiple Logon option but as I read it somewhere Mult.logons in productions system of users musbe set to off?
I am not sure what do do because I need to have option for employes to lgoin at the same time with one username/password.
If this is not possible is there any other way to achieve this? Also is there any way that one employe can enter/view data and other three employes can login at same time only to view data?
Any help is appreciated and <removed_by_moderator> !
Greetings,
Adi

Hello Jurjen,
I have no intention to voilate any of license agreement, I had to do it once in emergency.
@David Berry
Hi David,
There are four users in my office but I am not sure of exact total number of SAP users in my company.
@R. Voerman
Thank you very much for this information. I will try this definetly. Could you tell when I enter this parameter, then
multi_login_users option is ON, right?
@Julius Bussche
You can also assign it selectively to more users than the length of the system parameter field allows...
Hello Julious,
how do I this in transaction SU01, what do I need to change?
It's no problem form me to change this parameter but I am not sure if this is good because of security issues?
http://sap-basis-security.blogspot.com/2009/01/how-to-restrict-multiple-logons-of.html
Note:
"Multiple logons of users must be set to 1 in sap production systems. This can be allowed in DEV systems. But in production it must be restricted."

Multiple production systems in a track??

Hello,
Can anybody please let me know, if this is possible?
We have a production system (SCP) and a training system (SCN). I want to create a production track in the NWDI with just production systems. Can we have SCP and SCN in this track? I am asking this question because SCN gets its feed from SCP. SCN is a production system for a different wave.
Also, in another phase, we have the following systems (SD1, SRQ, SRV). SRQ feeds SRR (for dress rehearsal) and also feeds SR2 (for training in this phase). Also, SRV feeds SCP after cutover.
Could anybody please suggest the tracks for these systems?
Thanks!!

Hi Sunitha,
As you mentioned you have already existing track. there is an option in Approval tab. In approval tab click on history button and then click on forward button there it will show all your SCA files. from there you can transfer to any of the target track. in your situation create a track with required systems and give this track name in target system. then all the SCA files will be transfred to checkin tab of newly created track. from there you can do the general import process.
try this once hope it will works....
Regards,
Anil.

One BW - One R/3 Development - Multiple R/3 Productive Systems

Dear experts,
we are at the moment having a classical 3-tier system environment.
1) R/3 Development --> BW Development
2) R/3 Consolidation --> BW Consolidation
3) R/3 Production --> BW Production
Due to increased system load on R/3 Production it is planned to create an additional R/3 Production System which also needs to be connected to the existing BW Production system...BUT there will be no additional R/3 Development or Consolidation systems. The new Production system will be feeded parallel with transports fro mthe existing development system.
Question:
On BW side we will need to create Source system-dependent objects (Transfer Structures, InfoPackages, etc), etc. which are connected to the new R/3 system. But we cannot do that as we do not have a corresponding R/3 Development system connected to our BW development system.
Anyone has an idea how to approach this issue?
Thanks a lot!
Regards.
Joachim

Hi Joachim,
I have a rough idea. Can you go to RSA1 of your BW production machine, in menu tools->conversion of source system names. Add a new line, and assign r/3 consolidation machine as "Original Source System" the second R/3 prod machine as target source system. Save and try transporting again.
I haven't such experience before and it's only my guess (your case is really special). Please validate it first
If not work, a stupid way is changing this table after the first importing for r/3 prod machine1, then import again for machine2...
Regards,
Frank

Not able to change the data of test data containers in production system

Dear All,
We have created eCATT scripts in Development SolMan System and moved the transports to Production SolMan System. Customer wants to change the data at Test data containers and run the scripts in production system but we are not able to edit the data.
May be the reason is SCC4 transaction code has set the below option.
Changes and transports for client-specific Objects
u2022 No changes allowed
Customer doesnu2019t want to change the above option and wanted to change the test data containers to give different datau2019s and run the eCATT scripts.
Could you please let me know the solution for this?
Your help is really appreciated.
Thanks,
Mahendra

eCatt has the feature where you don't need to transport the scripts or test configuration to our target system. We can keep all our scripts and test data in Solman and run this script any other system in your landscape using the System data container and target system.
Maintain the production as one of the target system in System container in Solman and point that system while running the script. Change the test data in Solman to run this script.
Let me know if you need more information
thanks

Same logical system name for two productive systems - BW, PI issues

Dear all,
we have a productive system which serves two companies (different company codes). This system is connected both to BW and PI for both companies.
There is a requirement that these two companies must use their own system, so the whole landscape (dev,qa,prd) will be copied to different systems (different server with different system id).
As a result of the above procedure we wll have two different productive systems, as required, but we wll have the same logical system name for the two productive systems, which must be both connect to bw and PI.
However as far as I know:
- we cannot connect systems with same logical system name to BW,PI
- we cannot convert logical system name of the one of the two productive systems as they are productive and so this is not supported.
How can we overcome the problem?
Please advice.

> However as far as I know:

Right.
> How can we overcome the problem?
Since you split up systems (or plan to) I highly recommend booking an SLO service (http://service.sap.com/slo). Those people have to the tools and the knowlege to help you. I would not do this on my own.

Activate CHaRM using Virtual Systems in Landscape

Is it possible to activate a CHaRM project against a landscape that
contains virtual systems?
We currently have a Development system (DEV) with a virtual Test system
(QAS) and virtual Production system (PRD). These systems are marked as
Virtual in TMS and SMSY System Landscape. We have added these systems t
o
the Logical Components and created a new Solution Manager project and
want to activate CHaRM against this scenario. .
The TMS routes are defined with Dev -> QAS(virtual) -> PRD(virtual). Is
this scenario possible? Do the standard CHaRM activation checks (RFC's,
Authorizations, etc) get bypassed because these systems are virtual?
When activating CHaRM, we still receive the error that no consolidation
system exists for our Dev system even though the TMS routes have been
defined properly. However, since these systems are virtual, we cannot
add client information to them.
Thanks

A virtual system cannot export any TR. So any request imported to QAS cannot be exported

Multiple projects in n+1 landscape

Hello Experts,
We have a specific requirement to complete 3 projects in a stipulated time frame.
Requirement explained with the help of an example
-     Three projects to be completed in 12 months
Project 1  P1  Go live date 3rd Month
Project 2  P2  Go live date 7th Month
Project 3  P3  Go live date 8th Month
-     All projects have no shared workbench or customizing objects.
-     Projects donu2019t have any shared objects with the existing production support and client wants all projects to be in the existing production system. Introducing a new production instance is not an option.
-     Start data for all 3 projects is 1st month.
-     Existing landscape has
DV1  Development
QS1  Quality
PR1  Production
-     Intention is to introduce a n+1 system landscape and start the project 1.
Catch -     However with this concept P1, P2 and P3 cannot be started at the same time.
Approach to handle the scenario:
Introduce
One development system  DV2
Two quality systems  QS2 and QS3
Three transport groups  P1GRP and P2GRP , SUPGRP
All transports released to P1GRP from DV2 will only go to QS1
All transports released to P2GRP from DV2 will only go to QS2
All production support changes keyed in to DV2 released to SUPGRP will goto both QS1 and QS2.
This way production support changes can be tested along with the new projects and go lives can be staggered.
Question that a basis person would ask at this juncture:
If the project go lives are staggered and all of them are mutually exclusive, why isnu2019t project 1 and 2 done in production support path?
Issue:
o          Go live dates for projects may slip.
o     At some stage in the project 1 or project 2 some of objects may be shared causing issues with the production support.
Help required :
Has anyone come across such a situation in their porject ?
Would products like CTS+ in combination with CHRAM help to achieve this?
Any other recommendations?
Thanks in advance.
Thanks,
Rohit.

Hi,
As per my experience, you can have a separate landscape (DEV, QA, Mock Production system). These all three systems will be replica of corresponding system in your Live environment. So, you can do your development and testing here. So, as soon as go-live comes near you can transport all your change request to your live environment during cutover time. As a result your live environment will not be effected because of your future projects.
Thanks
Sunny

Erases the tranlations in productive system.

Hello,
We are going to productive in two weeks and we have a problem.
We have The Test instance (R/3 4.7 non unicode) with languages DE, EN
and ES.
Then we have the Productive system (R/3 4.7 Unicode) with languages DE,
EN and CS.
We have some programs that begin with /SIE/ and when we transport to
productive all the tranlations we have in porductive disappear. In the
Transport we select the options "Overwrite Originals" and "Overwrite
Objects in uncofirmed Repais".
Is there a way to not overwrite the CS tranlations in productive
without tahking out this two checks?
Now we can't upgrade to unicode the test instance.
Is there anothere way?
This is very urgent.
Thank you very Much
Pablo Mortera.

You should be using all your systems in your landscape as Unicode. If one is not, it should not be used for transports, specially translation.
Refer to note 0585116 concerning Unicode translation.
Why are you transporting from TST to PRD?
Let me know,
Leonardo De Araujo

Performing SPAU in Production System

Dear Team,
We are in the process of upgrading our Production system from EHP3 to EHP7.
We upgraded our Quality system with SPDD and SPAU transport requests from Development system and it finished successfully.
But after upgrading our Kernel in Production system and before performing the EHP7 upgrade, we applied two SAP notes in Production system, these notes were transported from our temporary development(un-upgraded) system(parallel landscape).
While performing the EHP upgrade in Production system, SUM has prompted us the below message
“Decide about Incomplete Modification Transport”
CAUTION: The program has found the transport "MEDK906662"(our SPAU transport) for SPAU but it does not contain all objects which need adjustment.
When we checked the log file it show that two objects are missing in the SPAU transport.We suspect these are the SAP Notes which we applied after kernel upgrade and are missing in SPAU transport request.
Please let me know how we can correct this issue in Production system. I know that SPAU will appear in Production system, but will the system allow me to re-apply/reset the SAP note in SPAU as this system will be un-modifiable.
Regards
Imran

SE06.
System Change. Global setting "modifiable". Componenents "modifiable". Namespaces "modifiable".
Client setting-> select client -> Automatic recording of changes, changes to repository and cross-client customising allowed, protection level 0.
If that doesn't work, give yourself SAPALL and try again.
If that doesn't work, contact SAP because something is messed up. I've successfully applied notes in P systems during upgrade. Including ones that modify SAP_APPL.

How to import transport of copies to productive systems

Hello,
I have been experiencing a problem that even the guys from admin could not solve (yet). I should say I work in a development team.
Imagine you have two landscapes, one DEV-QAS(1) to develop big projects and a normal DEV-QAS-PRD(2) landscape where my objects will be imported. After a new group of objects is finished in (1), we ask to import the workbench request in the STMS queue of DEV(2). After this, and after some small test, we create a transport of copies in DEV(2) where we include the first transport, release it and import it to the QAS(2) queue. After the tests in QAS(2) the idea would be to import the transport of copies to productive system PRD(2). But it does not work...
In STMS queue for PRD(2), there is no entry for the transport of copies. Also, when I tried to add the transport request to the import queue (via menu -> Extras -> Other requests -> Add), I get an error message stating that no co-files where found for the transport.
Does anyone know this problem? I suspect it can have sothing to do with the use of a transport of copies, but, if I don't use this kind of transport, how can I get objects from other systems to production?
Thanks in advance.
Davide Sepanas, Portugal

Davide,
Re your latest questions:
> 1) Why this problem with transport of copies doesn't happen from DEV(2) to QAS(2), since these systems are also not in the same transport directory?
>
I think the answer is in your original problem description:
we create a transport of copies in DEV(2) where we include the first transport
>
When you create a transport of copies you must indicate a terget system and I suppose you enter QAS(2) there. In that case the TMS will add the request to the import buffer of the target system when you export the request from DEV(2). I understand that you never have to add transports of copies to the import buffer of QAS(2) manually, which proves the TMS does this for you. However, for further imports into systems that are not designated as target system of the transport of copies, like PRD(2), the TMS will do nothing of the sort and you must add the request to the queue yourself - which in your case also means you have to forward the transport files first.
> Can we assume, then, that, where I was working before, all three systems were configured in the same transport directory, avoiding thus the problem with the transport of copies requests?
Yes, and that is the most common way of setting up the transport system. Having separate transport systems really only makes sense when sharing the transport directory between the dev, qas and prd systems (via NFS for UNIX, via network shares for Windows) is not possible, either because there is no local network between the servers or because some security policy forbids it. I'd advise you to certainly ask the question to your system admin.

Mark

ESR role in different development, test, and production systems

Hello,
I want to know the role of ESR in development, test, and production system. Do I have to install ESR in every seprate installated SAP CE machine??? or should It be centrally and development., test and production systems can use it?? Does software release process effects in the whole landscape??
does Test and Production system requires ESR??? or all used services are embed into released software SCA files to test and production system???
Regards,
Naeem

Hey,
as far as I understood the ESR is a design time tool, i think you don't need to have a productive instance.
I think it should be installed on your PI systems. And I would prefer to have at least a devel and a test installation, to
separate services on test machines from those who are running on productive systems.
as you can't differentiate the services by their name but just by their systems, you should have separate ESR Instances.
Nevertheless I think it could be possible to run only one ESR....
Kind Regards
Christof
