ERP shell creation package

For any ERP related package (except client deletion package), do we have to run "ERP shell creation package" at the very beginning?
The reason I ask this question is as follows:
To bring HR configuration to the target, we have 2 different methods:
1) client copy
2) TDMS package called "ERP initial package for MDC"
Therefore I have the impression that at least method 1) does not need a shell creation.
I am not sure whether method 2) needs a shell creation first or not.
Could you help explain?
Is there any other exception for shell creation?
Thanks!

Hello
No shell is not a mandatory step before TDMS ERP related package. General requirement of TDMS packages (time base or object based) is that the repository on both the sender and receiver should be identical. So in case the repository on both the system is already in sync then Shell is not needed. Also if there are minor differences in the repository then too it may not be required to do shell if the same inconsistencies could be removed manually or by importing some missing transports.
If the differences between the two systems are many or if the receiver system needs to be build from the scratch then Shell is required.
I hope that helps

What is the "BW shell creation package for BW system" in TDMS?

I see for lower version of SAP systems such as 4.6 and BW(e.g.3.0, etc), there is a "shell creation package " for those
types of systems.
Could you explain what is that for?
Thanks!

1) where to find the info about the copy sequence such as: first shell creation, then initial package or whatever, then ...?
> TDMS solution operation guide will be helpful, the same is available at SAP service market place. In short the sequence is -
first shell (only if the repository is not in sync) then initial package (ex. TDTIM) and then refresh packages (as an when needed)
2) for HR we do not have shell creation, what we have is "initial package for master data and customizing" , the next step is "ERP initial package for HCM personel dev. PA & PD". Why we do not have shell creation here?
> For HR as only few objects are transfered the need of a full shell system does not arise. only the object to be transfered are synced.
3) Will TDMS replace system copy for ERP, BW, CRM completely?
> Shell will not replace them but we may say that it will supplement it. When you need a complete copy means repository along with application data then you need to go for system copy but if you only need repository to be copied from source to destination then shell is helpful. Also it should be noted that Shell is an TDMS package whereas System copy is a SAP standard tool.
I hope the above response is helpful.

TDMS 3.0 for ERP 6.0: step by step procedure for TDSH6 Shell creation

Dear All,
I need to perform shell creation. I have never done this and need help with step by step instructions.
I need to refresh my my development system with a TDMS shell creation from production client in production system.
I am familiar with TDTIM and performed many TDTIM copies. I have gone throught the master and operational guides for TDMS also.
I would try to list down my understanding so far after reading the guides.
Please correct me if I am wrong ang also suggest correct steps.
1. All my three systems (central, sender and receiver) are ready from installation point of with with authorizations and latest SPs.
2. I log into Central/Control system and start a new package "ERP Shell creation package for AP Release higher 4.6 "
3. AS I have never executed this option I do not know what are the stps inside it.
   But I assume I should be asked for the source client details from which shell needs to be creates. (000 or pruduction client)
   What type of shell : slave or master?
4. During the shell creation from sender system client, is there a downtime for sender system.
5. Once the shell creation is done an export dump will created.
6. I perform all the preprocessing steps of a homogenous system copy on the receiver systems.
7. Stop receiver system, start sapinst database instance installation with homogenous system copy with R3load option.
8. Provide the export dump location to sapinst.
9. After database instance is installed, perform system copy specific post processing steps.
10. Afte the system is ready it has only one client 000 now available in development system and i need to create a new cleint from 000 which will act as my new development cleint.
I request all you experts to please provide your comments at the earliest as activity would be starting from 5th of this month.
Regards,
Prateek.

Hi,
Let me answer your questions.
Some queries
1. Is there a downtime for Production system (sender system).
   SAP recommends that nothing much should be going on during the export of the Sender(PRoduction) system, but so far i have never encountered an issue doing the export in online mode.
2. Shell creation works on both Production and 000 client or only Production client,
   Be carefull!!! - A Shellcreation is a normal Homogenous Systemcopy using R3load. You will create a 'new' system with the DDIC and clientindependent customization of the Sender system. ALL former data of the target system will be deleted.
You mention that you will refresh a development system that way. Please be aware of the implications that a development refresh contains. That said. After the refresh you will have the 000 client and parts (users ... authorizations of sonder) of the other clients on the new system.
3. when I import the the dump using sapinst, how many clients are available in receiver systems.
See above. All client configuration will be available, but nearly no data will be in these clients except 000. A manual part of the Shellcreation is to clean up the target system (delete the clients that are not needed) This is a fast process.
4. Soem where in the guide it is mentioned that downtime depends on the type of shell I create.
Kindly suggest should I create a master shell or slave.
Hm. The master shell is just a concept that you create a complete new system and put that system into your transport landscape without filling it with data. You can then use that system as the source for a normal (database dependent) systemcopy without impacting your prod system. The result is a very small copy that can be repeated very often without an impact to prod/QA...
Downtime is as described in point1 not required
5. Once I execute this activity of shell creation for lets say receiver system A, then can I use the same export dump for second receiver system B.
Yes
6. Lastly please suggest the activity execution time as customer has provided us 2 days to execute this activity.
This depends on your knowledge of homogenuous systemcopies and the preparation + some items like size of stxl and other tables that will be exported/imported. If you are very familiar with the systemcopy process using R3Load 2 days are feasable.
I have seen shellcreations done within 1-2 days but also much longer ones!
As a prerequisite i would always recommedn to have the latest R3* + migmon exe available on sender + target.
I hope i have clarified some of your items.
Best Regards
Joerg

TDMS shell creation - R3szchk running longtime

Hi,
I am running a shell creation package, in Export ABAP phase R3szchk running long time and there is nothing written to log file
-rw-r----- 1 root sapinst 0 Oct 4 19:56 /tmp/sapinst_instdir/ERPEhP4/LM/COPY/DB6/EXP/CENTRAL/AS-ABAP/EXP/R3szchk.exe.log
where else I can check to find out the issue?
Thanks
Din

Thanks Pankaj for the valuable information.
---The size of exports may depend on the data in your client independent tables. There are certain client indepedent table which hold a lot of data for example STXL, STXH and DYNP* tables. It also depends on the volume of custom development that you have done in your systems. Most of the client independent tables are exported in full duing shell.
I could understand that. I ran an optional activity u201CCheck size of large tables (optional)u201D in TDMS Shell package, it returns witj some large tables, such as
STXH- 190,854,900 KB
STXL- 26,819,840 KB
DYNPSOURCE- 20,452,251 KB, some of these are independent and some are dependent tables. For ex. STXH is dependent table with size 190GB, does it means that this table will be exported in full during shell export?
However, you need to be sure that because of certain mistakes you are not exporting the complete system (including application data). As stated by Marcus, you need to make sure that you are using Migration monitor in manual mode and that you configure the Migration monitor control file with correct parameter values.
I think I configured import monitor control file correctly and started it manually.
Here is the import monitor startup log:
Export Monitor is started.

Migration monitor in TDMS shell creation

Hi,
I am working on a TDMS shell creation for ECC system, I have few question..
1) Is it mandatory to run migration monitor manually while in both exporting and importing database with R3load option in tdms shell creation or only while running R3load export?
2) How to run export monitor activity in background?
3) How to parallel R3load processes to export a single package instead running one r3load for each package?
OS: AIX
DB: DB2
SAp ECC 6
Thanks
Praveen

Answers to your questions are below -
1) It is mandatory during the exports of data from the source system.
2) It should not be run in background
3) Use table splitting using R3TA, but that should be done before exports.

TDMS for BI - shell creation and SMIGR_CREATE_DDL

If a homogeneous system copy of a BI system is done, it's necessary to run the job SMIGR_CREATE_DDL because depending on what database is used, special SQL scripts for tables must be used (concerning primary keys).
How does that integrate into a shell creation? Is the shell creation process aware of those scripts? I mean, it's theoretically possible that the SQL scripts has a table that is excluded from being transferred?
Markus

Markus and Pankaj:
I have created a SHELL (BW) using Markus' way as listed below.
Because Markus did not mention that SMIGR_CREATE_DDL should be run at the beginning, so I did not run it.
So how to determine in the created shell what is missing?
We do have partitioned tables and bitmap indexes.
Thanks!
Here is the way provided by Markus:
I basically do shell creation as follows:
- install the latest system copy tools (R3load, R3ldctl, R3szchk, libdb<database>slib.dll)
- create an installation directory and give full permissions to <sid>adm and SAPService<SID>
- create a directory for export location and give full permissions to <sid>adm and SAPService<SID>
- open a cmd.exe as <SID>adm, step to the installation directory and execute "R3ldctl -l R3ldctl.log -p ." (note the "dot" which means actual directory)
- in parallel start the client export of client 000 in source system using SCC8 (profile SAP_ALL) and note the file names you get in the last dialog window
- when R3ldctl is finished give permissions to SAPService<SID> for all files in the installation directory
- proceed with TDMS
- when you are at the point to start the system copy start sapinst, choose system copy and select start migration monitor manually (VERY important!)
- sapinst will run R3ldctl, R3szchk and then prompts you to start migration monitor
- step to your normal installation directory (c:\program files\sapinst_instdir....), open export_monitor_cmd.properties and adapt the file. The import thing is, that you need to point to YOUR DDL<DB>.TPL file you create in step 4 (in my list here)
- start export_monitor.cmd and export the system
- proceed with TDMS to adapt the database sizes (DBSIZE.XML)
Import:
- if you have an already installed system uninstall it
- start sapinst normally, choose system copy and point to the export you created
- install the system normally (as a new installation)
- if you want to make sure the import works as the export choose "start migration monitor manually"
- if sapinst stops and requests you to start migration monitor copy the kernel from source system to target system
- configure import_monitor_cmd.properties and start migmon
- logon in client 000, start transaction STMS and create a domain (basically only a transport profile will be created)
- start program BTCTRNS1 (this will suspend all jobs from the source system but not delete them)
- copy the files from the client copy to TRANSDIR/cofiles and TRANSDIR/data and import them to client 000 (either use STMS or use command line tp)
- adapt profile parameters (RZ10)
- run SGEN
- invalidate connections in SM59 that point to other production systems
- finished
- to re-enable all the jobs run BTCTRNS2, however, I'd do this only if you're sure you have invalidated RFCs and or sending jobs (e. g. from SCOT)

SAP TDMS System Shell creation

Hello,
I am new to SAP TDMS. I want to know about System shell creation.
Is System shell used to create a totally "new system" or can it be done on an existing system? Can it be done on an existing system by using a separate client??
If we use existing system what happens to its already present data. As per the Operations guide it says we need to do a Homogeneous system copy by using TDMS tools.This will delete the data in existing system.So does it mean all database content will be deleted or only the client specific data?
Many Thanks.
Ravindra

I'd create a client copy (SAP_UCSV) from the source system.

Shell creation issue

Dear experts, I've got a question regarding shell creation of TDMS.
I've finished the export from ECC IDES system (SR3). The size of export files are over 30GB... is it normal? Can I reduce the data? Since it'll take me more than 200GB disk in target system.
Is it been setup in the step of "Determine Tables to be Excluded from the Export"?
Which data can be reduced in the table regarding IDES shell creation?
Thanks!

Hi Jett
Your first question is not very clear to me -
Seems that, the data folder of export is still the same as before. Is it normal?
>I think you mean to say that the size of the data folder of export is of same size as before. Yes that is normal. However i feel the doubt that remains in your mind is that you want to be sure that its doing a reduced transfer and not a full transfer. Well you cant make a decision based on the size of the export folder. To decide that you can do the following -
Pick one excluded table and in the exports folder try to search for its existence in the .TOC files. If you find it in any of the .TOC files then it indicates that a full transfer is happening instead of a reduced one. If you dont find it in .TOC but you find that excluded table in .STR files that indicates that a reduced transfer is happening and everything is fine. The existence of the excluded table in .STR file indicates that the structure information of the excluded table will be transferred although the data is not getting transferred.
Regarding your second set of queries -
Please understand that there are two parts to shell creation one is excluding the data to be transferred for a set of tables, so no data at all get transferred to the target system for all the excluded tables. Second part is that how much filespace (on target system) should be allocated to tables which are there in the excluded tables list, by default the import process will assign same space to a table in target system as the space allocated to it in the source system. So if a table for which no data is getting transferred was of size say 10 MB in sender so the import process will allocate a filesize of 10 MB to the table in target system also although it will be blank. To avoid this and to reduce the overall size of target system, we reduce the sizes that should be allocated to the excluded tables in the target system in the activity "Determin and Modify Size of Tables".
Now for the question what do the ratios mean and on what basis do we assign the ratios-
>Say for example Ratio20 means that the import process will assign 20% of the original size (in sender system) to the table in the target system. Regarding on what basis are the ratios determined - The ratios are determined on the basis that how much data do you expect each table to hold later on. So this depends on which process of TDMS (vis TDTIM, TDMDC, TDTCC) do you want to execute after shell creation. In case of TDTIM process type it may also depend on the period for which you want to transfer the data. For this reason we have provided various templates (vis TDTIM, TDMDC etc) in the activity "Determin and Modify Size of Tables". So we have tried to build this intelligence into the system. So if you want to excute a TDMDC scenario after shell creation then you should choose the template TDMDC in the activity "Determin and Modify Size of Tables" and the system will automatically assign defferent ratios to different tables.
In my last post i had suggested that if you want to further reduce the size of your target system (although the assigned template will automatically reduce the size of the target system) you can do the same by further reducing the ratios for the tables for which you dont expect much data to be transfered. This functionality of altering ratios for certain table or set of tables is available in the activity "Determin and Modify Size of Tables". SAP already delivers ratios which will be optimum for different tables, if you want to override those setting and provide your own ratios then it should be done at your own risk.
I hope this post explain you the entire concept. In case you have some doubt feel free to write again.

Pankaj.

TDMS shell creation

Is TDMS shell creation for the ABAP stack only?
What happens in the ABAP+Java systems?
Thanks,
Sri

Hi Pankaj,
I don't think TDMS is meant for JAVA. At preset It is only meant for ABAP stack to transfer data using different senarios.
You can transfer the data from source and at the same time the Java settings in the target remain the same.
Thanks,
Sridhar

Shell Creation : Export Database

To create the target system with shell creation :
1. I've create control file in the folder E:\sapinst (*.TPL and *.STR)
2. I've execute the steps "Define Environment Parameters and Excluded Tables"
3. I've executed sapinst --> Export Preparation. The sapinst folder is :
C:\Program Files\sapinst_instdir\NW04S\LM\COPY\ORA\EXP\CENTRAL\AS\PREEXP
4. Now I would like to execute sapinst --> Database Instance Export, but my question is : where and when I must copy the fles create in step 1 ?
Thank's in advanced
Francesc

Hi
You have to make sure that the export process uses your current installation directory i.e. E:\sapinst (for your case) and not the default one i.e. C:\Program Files\sapinst_instdir. That is the main requirement of Shell creation process.
To achieve the same you may need to do the following -
> Incase you are not using migration monitor then you should start the export process from the current installation directory (E:\sapinst) and you should start the SAPINST tool with the parameter SAPINST_CWD and set it to E:\sapinst. for ex.-
e:\sapinst>J:\xxx\yyy\xxx\zzz\SAPINST SAPINST_CWD=E:\sapinst
> Incase you are using migration monitor then you should start it in manual mode and you should specify it to use E:\sapinst as the installation directory.
I hope this helps

Pankaj.

Is an existing client the only prerequisite for shell creation?

I am preparing my first shell creation. From what I read, I get the impression that an existing client is
the only prerequisite for a shell creation. I already created the CPIC user and installed DMIS_ on the sender and central systems.
Could you confirm? Thanks!

TDMS Shell is a form of system copy where you copy an existing source system into a target system but only the non-application related data. TDMS Shell is a prerequisite for other TDMS processes.
Regarding prerequisites for Shell - all prerequisites and preparation that apply to SAP system copy apply for Shell also. Refer to SAP system copy guide for the same.
Best regards
Pankaj

Shell Creation - Transportation history

Hi all
one question:
What happens to the transportation history, if I create a Shell Creation ?
Thanks for help

Hi,
after the migration you need to apply a delta list of transports meaning. Those that are implemented in QAS and not yet in PRD need to be imported again to get the same situation as it was before the migration.
The transports that are in QAS and not released yet are lost.
Best thing to do is to use a virtual system or to cleanup the STMS buffer afterwards so you have a new starting point for other migrations.
Hopefully this helps.

Eddy

Why use shell creation?

Hi all,
Why should I use shell creation... is it to set up a new client in an existing system or to set up a whole new system (development, quality, learning)?
Thanks, Erik

Hi Erik,
Shellcreation is used to create/refresh a new SAP System (like a Systemcopy)only with the repository information and structure of the source system. So no transactional data.
IT works not on the client but on the Systemlevel!
Best Regards
Joerg

What is the "shell creation" in TDMS?

I cannot find the exact definition of above term "shell creation". Would you please help? Thanks!

In TDMS, there are different ways of selecting data from the production server. So there are different Process Types.
Shell Creation is one of those types.
SHELL CREATION- Migrated data contains only cross-client data and the required client-specific user and address data, but no other client-dependent data.
Hope this answers your question
