System Copy Procedure
- system copy it's better to be done with an offline backup, because no tx logs should be applied after
- we can schedule an offline backup via crontab, or just run the backup_offline.ksh script
- before starting the backup stop SAP, check if pmon is running, sap, etc....
- start the backup and meanwhile check the log file /oracle/S01/102_64/bin/namelogfile.log with fast –f ./namelogfile.log
- after the backup is complete verify if all the data files were backed up correctly
- delete te data files *.data* from /s01/sapdata1+2+3+4  ---find . -name "*.data*" -type f -exec rm {} \;
- create the same directory structure in /S02/sapdata1+2+3+4
- after we should check the permisions on the new directory structure
- next step is to unmount the /S01/sapdata1+2+3+4
- next we should mount /S02/sapdata1+2+3+4
- the backup log file is rdyzhxtr.rsb
- next we have to modify the enviroment variable and chnage it from /usr/S01 to /usr/S02
- the backup file is bdyzhdsn.aff
- before running the restore try brrestore -b bdyzhdsn.aff -m all -c -q check  --to check for some eventual errors
- restore using brrestore -b bdyzhdsn.aff -m all -c
- after resore try to start SAP...hope for no errors...  :D
