System copy for ECC 6.0 system no j2ee process under MMC
Dear support,
This has been observed in many of our clients system which are on ECC 6.0 abap+java system, that after we perform system copy from one system to another
whether it is Oracle platform or mssql server platform ( system copy for oracle using controlfile script ) ( system copy for mssql with restoring .BAK file from source )
systems are running fine but j2ee process table showing no processes like
SDM, dispatcher , server0
even configtool and go.bat are unable to connect.
Is there any specific settings we do after system copy for java side
Please let me know at earliest, as it is most strange thing i have seen in almost all my system where system copy is performed.I have already raised a post against this error but at that time i was not aware of this system copy reason behind the same.
Best regards,
AjitR
Your main problem is not, that you don't see anything in MMC (the system can be added manually without much hazzle) - but is, that you database content of schema SAP<SID>DB does not match the data found on the filesystem.
If you copy the filesystem structure from production to test/qa, you need to make sure, the database and filesystem are in sync. You will have two problems if you "just copy them":
- They are out of sync because your production was going on running since you copied the backup files
- all configuration (all java property sheets) is/are set to point to the production system instead of the test/qa system
I doubt, that it will work if you copy it over. This also explains, why you can't even start configtool, because it points to the wrong system/schema. You MAY be able to fix all that manually, but you may encounter subsequent errors because not all configuration is documented, you would need to step into the whole j2ee tree and look at each and every propertysheet to find out, whether it's correct or not. Additionally, the database may have other information (see above) and all that may become overwritten during bootstrap.
So - the best way to get your system up and running quickly is to start sapinst on the source system, export your Java instance (not using ABAP but the Java dump) and re-importing that to your test/qa system.

System copy for PI 7.0 system
Hi,
We are doing system copy for complete landscape and every time we used to perform PI system copy using SAP standard procedure of backup/restore, Java exp/imp.
But can we use another approach of exporting IR/ID from source to Target. Because we do not have any transactional data in PI and what are different things that we need to take care if we export individual components.
Like new ports, we20,we21, IDX1,IDX2
Thanks,
Venkat.to elaborate more,
we are doing system copy from Dev to Sandbox (we already have working sand box)
I am planning below steps
1) export all the software components from development system - Integration repository and Directory
2) Adjust the transport path in SLD (source Dev and target Sandbox)
3) Import the software components to Sandbox for Integration repository and Directory.
4) change user-passwords to match sandbox authentication.
Please let me know if i am missing any steps and has any one did a copy by above procedure.
Thanks,

Logical system names after system copy for SAP ECC 6.0
Hi!
We successfully installed SAP ECC 6.0 system as system copy.
All the logical system names of old system have been copied to new system.
Question
What is the approach to change the logical system names for new SAP system?
a) just via tcode SCC4
b) via BDLS
c) other tcodes, reports
Thank you very much!

Homogeneous System Copy for 4.5B/DB6/W2K ?
I'm looking for the documentation on doing a homogeneous system copy for an R/3 4.5B System for a client. They are running DB6 on Windows 2000. I've searched Service Marketplace and can only find doc's back as far as 4.6C. I can't find the one for 4.5B.
The client is looking to migrate the current system to new hardware and then subsequently upgrade to ECC 6.00, but that part is off a piece. The first part is to migrate the system to the new hardware in order to solve some space and performance issues.
If anyone can point me to the docs, or has a copy on their local machines they can send me, then please let me know.
Thanks.I suggest you open an OSS call under BC-INS and ask for the guide there.
Since 4.5B is out of maintenance and you/your customer has (hopefully) an extended maintenance contract for that version they will give you that guide.
If you do NOT have them, you might be pretty lost in case of a problem, if you have the guide or not...

Transfer rules are not exist for ECC Quality source system in BI Dev
Hi,
I Connected BI Dev system To ECC Dev and installed the sales, purchasing,... data flow, but here i am not getting the quality data to show the reports, to get Quality data I established the connection between BI Dev and ECC QA, while installing the transfer rules for the ECC QA data sources there no transfer rules are exist(only some of them exist) in the business content, but all the update rules,... are exist, when i right on the data source say create transfer rules it is proposing App praposal.
When i select source system as ECC dev while installing the transfer rules i can see all the transfer rules, but when i select source system as ECC QA i can see only some transfer rules.
only problem with transfer rules(some of them exist), for remaining all objects are properly existing in business content for ECC QA source system.
Regards,
chandraHi Fayzrakhmanov
Thanks for the quick reply. We are not moving the stuff to QA. We are only connecting QA ECC system to BI Dev. We already have datasources moved to ECC QA and created source system for ECC QA in BI Dev.
The problem is I am not able to get Business Content transful rule for new source system. We I can find some but not all unlike development.
Help on this would be appreciated.

SPLIT_2-20001410.SAR
I would have additional questions.
1. In note 516246(System copy for SAP Systems based on SAP Web AS 6.20)
it is mentioned to download the latest version of R3LDCTL and apply it
to the system. I have following questions:
under service.sap.com/patches
i found only
R3LDCTL
Support Package SAP KERNEL 4.5B 32-BIT Windows Server on IA32 32bit
ORACLE
Is this file ok?(I will perform a homogeneous system copy of an 4.7x1.1
system)
If the file is ok what is meant as apply?(put it in kernel directory?)
2. Very similar question applies to file R3szchk
under service.sap.com/patches I found only
R3szchk
Support Package SAP KERNEL 4.6C 32-BIT Windows Server on IA32 32bit
ORACLE
Is this file ok?(I will perform a homogeneous system copy of an 4.7x1.1
system)
3.In same note(516246) the SAPinst CD is mentioned. How could I get it?
4.On the Source system I have kernel 640. I guess I have to copy the
content of this directory to the target system also. But in which phase?hi,
first my question GGG
-> by which means do you plan to copy? brbackup/brrestore? r3copy? r3load?
ad 1.
SAPNet -> Patches -> Add. Components -> SAP Kernel -> 32 BIT (uni oder non-uni depending on your environment) -> SAP Kernel 6.40 32-bit -> Windows Srv -> Oracle -> R3ldctl_6-20000185.SAR (13.07.2006) is the right file (your kernel is 6.40!!!)
ad 2.
SAPNet -> Patches -> Add. Components -> SAP Kernel -> 32 BIT (uni oder non-uni depending on your environment) -> SAP Kernel 6.40 32-bit -> Windows Srv -> Oracle -> R3szchk_12-20000185.SAR is the right file (your kernel is 6.40!!!)
ad 3.
SAPNet -> SWDC (= Downloads) -> Download -> Inst. and Upgrades -> Entry by applic. group -> SAP Applic. Components -> SAP R/3 Enterprise -> Ent. 47X110 -> Installation -> Windows Server -> Oracle -> CD SAP R3E 4.7x1.10 SR1 SAPINST ORACLE (CD N° 51019679)
ad 4.
not really....it depends on the strategy (see my question above)...you first install the database software (oracle), then the central instance using sapinst, afterwards you will install the database instance using sapinst as well; while installing the db instance you have to chose db copy (or homogeneous copy, system copy) as the "database installation method" if you choose to copy the database files or did a backup if you choose to use the export/import method (using standard r3load) you will use the SystemCopy method as well but you will point (later on) to the directory where you (source) db export lies.
brrestore or copy method:
=========================
sapinst will popup at the appropriate point that the db load has to be done and depending on your strategy you have either to restore or copy files...
by the way: did you already export/backup/copy your source system?
if any further questions arise feel free to post

Java WAS System Copy for non-SR1 Systems
Hi,
I found the document describing the Java WAS system
copy for NW 2004SR1.
However, has anybody successfully copied a Java
WAS system (Especially if the SID was
changed) which was not SR1?
I understand how to copy the datafiles, recreate the
control files, adapt the default and instance
profiles, etc..
However, I am not sure which other parameters,
XML files, or database entries need to be changed.
This is for a development system (I wouldn't do this
for a production system).
Any information from somebody who succeeded to do
this would be greatly appreciated.
Thanks,
IFHi,
for system copy of SCM 4.0 use the document system copy for webas 6.20
https://websmp205.sap-ag.de/~sapdownload/011000358700002645032002E/syscopy620_140803.pdf
perform DB copy as note 151603 :Copying an SQL Server database (homogeneous system copy)
apply sap note 551915 - R/3 won't start after database restore or database copy after DB copy.
if you want to perform livecache copy also
check Note 457425 - Homogenous liveCache copy using backup/restore
also consider Note 886103 - System Landscape Copy for SAP SCM

System Copy for SAP Netweaver 2004 ABAP and Java
Dear Friends,
We are planning to do System copy for CRM 4.0 (ABAP+Java) from PROD to Quality.
Production has following
Production
CRP (ABAP+JAVA, Oracle 10g)
CR1 (Java Standalone, CRM Applications, Oracle 10g)
CR2 (Java Standalone, CRM Applications, Oracle 10g)
Test
CRT (ABAP+JAVA, Oracel 10g)
CR1 (Java Standalone, CRM Applications, Oracle 10g)
As per my understanding perfrom System Copy in two methods
1. Using Offline backup of CRP from the Split Mirror backup.
2. Export of the CRP from the Split Mirror backup.If you have Split Mirror available you could definitely use it. Redirected restore or export/import are the alternatives.You could also use file copy (system offline is preferred).

Homogeous system copy for machine refreshment
Hello SAP expert,
I'd like to migrate our sap system() from power5 to power7, and the host name and the ip address will be kept unchanged on the power7 machine. We want to use homogeous system copy for db6 to migrate the sap system for testing. And after the testing, we want to just use db2 backup/restore to replace the database without system copy again. I know there are several steps in sapinst after db restore when I do a system copy, but the hostname, ip and user are unchanged, so I think there is no need to do a system copy again. Could someone help confirm that?
And we also want to seperate DB instance and CI to different machine, can we just do a db backup/restore for this case too? And I am not sure if some information about CI and diaglog instance is recorded, if so, I just concern there is some inconsistency if I just replace the database instead of do a homogeous system copy again.Hi Sunny,
Is those report very key? The ip, hostname, system user will keep unchanged and only the machine will be changed from AIX5 to AIX6, so after I do a whole homogeous system copy for the first time and all sap related files are already moved to the new machine, so the next time I want to restore the db with the backup taken on AIX5 to new machine directly without reinstall sap system, it will reserve some time and reduce the effort. Do you think if there is any problem if I do this? Thanks. -
Homogeneous system copy for SQL server 2005
Hi All,
I am currently investigating for the method to perform system copy for a PI system with SQL server 2005 database. Using the System Copy for SAP Systems Based on NW 7.0 SR2 ABAP+Java as guide, I can see reference to Note 151603. However, I am unable to get a copy of that note. Searching for the note from the official SAP Notes Search area indicated that it is currenytly only avaiable internally.
Would anyone know where I will be able to get a copy of that note?
Thanks,

PI is version 7.1 (not 7.0) - so you need to use a different system copy guide.

No system found for component and Evaluation system in the Project
Hi Folks ,
Im facing this problem when im trying to Execute the T-codes from Solar01 of the Transactins Tab by Selecting the Line item and clicking on Execute button. Following is the Error and there no logs for it.
No system found for component and Evaluation system in the Project
Even i have checked with the RFC settings and Logical components are right
Please do suggest me - This is PRD issue . Try to do the needful .
Thanks in Advance
Amrita
Edited by: Amrita Amrita on Dec 3, 2009 12:53 AMHi all,
I've had the same issue with regards to getting the error below when assigning transactions to a Blueprint business process.
"No system found for component and Evaluation system in the Project"
But I think I have solved it and seems pretty simple to change the system role from Evaluation System to any other that is relevant in your landscape.
Go to transaction SOLAR01 > Click on the first level of the Project Name (Under Business Blueprint Structure) to select the Project.
Click Business Blueprint in the Menu > System Role > Choose the relevant System Role (in my case Development)
Click Copy
This should replicate to all nodes and then you should be able to assign transaction to the business processes.
Quite strange and seems simple, I checked the Solution Directory, Solar Project Admin etc etc but couldn't find the solution until this which should work.
If not, there is a similar work around which also works.
Go to transaction SOLAR_PROJECT_ADMIN
System Landsacpe Tab
Systems subtab
Click System Role Assignment
Remove the Evaluation System (or all those not relevant to your Project and Logical Components)
Save Project
Go to SOLAR01 and it should reflect it in the Blueprint.
You can always go back to this and add the System Roles you removed and the Blueprint will reference the correct Role.
Hope this helps everyone,

System Copy Guide: Exporting the Source System Using SAPinst.
Hi Gurus,
I am trying to do Unicode conversion of ERP 2005 SR3 on Oracle/WS2003
The preparation steps are OK
When I execute the last Phase using Sapinst : "database instance export",
it finishes within one minute with the message "Database instance export has been completed succesfully"
but without exporting data.
I have follow up Unicode Conversion Guide and System Copy Guide System Copy for SAP Systems Based on SAP NetWeaver 7.0 SR3 ABAP+Java.
What could be wrong here?
Thansk for your help
MartialSo you need to set an environment variable
SAPINST_USE_HOSTNAME = <your-virtual-hostname>
for the user executing sapinst.
