Preparations
General Information
This document is focused on the JAVA part of the homogeneous system copy. It doesn’t describe al the necessary steps for the ABAP part. I assume that this is more or less well-know.
Documentation
I have used the following documentation:
• System Copy for SAP Systems Based on SAP NetWeaver 7.0 SR2 ABAP+Java.pdf
• Note 970518 - Hom. Het.System Copy SAP NetWeaver 7.0 (2004s) SR2.pdf
• Note 784118 - System Copy Java Tools
• Note 831812 - Config Tool shows incorrect parameters after System CopyBullet 1
• OraBRCopy.pdf
DVDs
You need to have the following DVDs:
• Installation Master
• Kernel Unicode
• Kernel NonUnicode
• JAVA Components
• Oracle Client
Note: you only have to use the NonUnicode DVD if you have a non unicode system.
Source System This section describes the action which have to be taken on the Source System. How to create the MIGRATION EXPORT CD image. This image contains the data of the exported system, and which you use to install the target system.
1 Create an offline backup of the source database, preferably a backup on disk.
2 Create an installation directory:
mkdir /usr/sap/trans/systemcopy (or whatever you like)
chmod 777 systemcopy
Note: Preferably the target system should also be able to access this directory.
3 Download ORABRCOPY.SAR according to note 784118 and copy the archive to the installation directory.
Unarchive ORABRCOPY.SAR
SAPCAR -xvf ORABRCOPY_2-20001410.SAR
4 Execute the OraBRCopy Tool
Logon as the ora user on the source system
./ora_br_copy.sh -generateFiles -targetSid <TARGET_DBSID> -tnsAlias <SOURCE_DBSID> -password <system’s password>

As a result of this action you will find three additional files in your installation directory:
- CONTROL.SQL
- CONTROL.TRC
- ora_br_copy.log
5 Extract the SAP installation software from the Installation_Master DVD
Logon as a root user
cd /usr/sap/trans/systemcopy (the directory you have created at step 2)
<path of the Installation_Master DVD>/sapinst –extract
6 Start SAPinst
./sapinst SAPINST_USE_HOSTNAME=<central instance hostname> <path of the Installation_Master DVD>/product.catalog
7 Choose the following path:

Target System This section describes the actions which have to be taken on the Target System. How to import the MIGRATION EXPORT CD image. As I already mentioned I focus on the JAVA part. The document describes the Installation of a new target system. If you want to refresh the target system, just make a copy of your profiles, environment settings, ORA sqlnet files etc.
Preperations
1 If necessary, make a copy of your profiles in the SAP profile directory, a copy of the environment settings of your sidadm and oracle user and your ORA sqlnet files. Note: Maybe you want to save some other files as well.
2 Clean your target system. Delete your oracle datafiles as you would normally do with a homogeneous system copy.
Central Service Instance
1 Create an installation directory, extract the SAP installation and start the installation.
2 Install the Central Service Instance.
Choose the following path:
Additional Software Life-Cycle Tasks
System Copy
Oracle
Target System
Distributed system
Based on AS ABAP and AS JAVA
Central Service Instance (SCS)
Choose next and follow the instructions on the screens.
