How to Do SAP System Copy? – A Step-byStep Guide http://www.ivobe.com/sap-software/how-to-do-sap-system-copy/
An SAP system copy is one thing a SAP Basis administrator will undoubtedly be asked to do. It is common for companies to want their SAP test system to look like their production system and thus, will require a copy of SAP system. It may even be on a regular basis (i.e. quarterly). It is our intention to walk you through the steps of performing an SAP system copy by detailing (1) pre-copy steps, (2) copy steps, and (3) post-copy steps. This procedure expects that the SAP system and Oracle are already installed and the system copy is just a database switch.
A. Pre-Copy Steps 1. 2. 3. 4. 5. 6.
Note what date / time to which you will restore. Issue a freeze on transports to TEST. Emergencies will then go directly to PRODUCTION (if a different TEST system is not available). Note all transports that have not gone into PRODUCTION, but are in TEST. Note all transports that have gone to PRODUCTION after the date / time of the restore point. Shutdown SAP and Oracle on the TEST system. Remove all Oracle data files on TEST.
B. SAP System Copy Steps Description
Modify Control File
Using the restore date and time, copy PRODUCTION data files, log files, and controlfile from tape to TEST.
Modify the control file to match the directory paths for TEST.
In SQLPLUS, perform the following command: ALTER SYSTEM SET DB_NAME= SCOPE=SPFILE;
Use the Sqlplus command: RECOVER DATABASE USING BACKUP CONTROLFILE UNTIL TIME ‘YY-MMRecover database
DD:HH24:MM:SS’; The date / time will depend on the time you want to restore to. After this is complete, startup Oracle.
Check R/3 Connection
R3trans –d If R3trans –d does not give a 0 return code it will be impossible to start SAP correctly.
Start SAP for the post-copy steps.
