Hi,
The steps of database copy are as below.
1. To make Database copy between two systems, you have to check file size on
Target System.
Use commands:
df -k
bdf (HP-UX)
2. On the Source System, check the files which are going to move.
Use commands:
su ora
svrmgrl
connect internal;
select name from v$controlfile;
select name from v$datafile;
select name from v$logfile;
3. Release all change requests on source system.
4. Shutdown database (Source system)
Use commands:
su - adm
stopsap
5. Copy the controlfiles, datafiles, logfiles from source system to target
system.
Backup via tar
ftp or rcp
For example: You can write a simple script.
rcp r src_server:/oracle/SRC/sapdata1 /oracle/TRG
rcp r src_server:/oracle/SRC/sapdata2 /oracle/TRG
rcp r src_server:/oracle/SRC/sapdata3 /oracle/TRG
or for backup
tar cvf /dev/ sapdata* dbs origlog* mirrlog*
6. Copy $Oracle_Home/dbs/init.ora parameter file from source system to
target system. Change all old SIDs to new SIDs except db_name parameter.
Save it with old SID name.
7. On the target system, change parameter /dbname= on
parameter file /usr/sap/trans/bin/TPPARAM
8. Change all owners and groups.
Use commands:
With root user.
cd /oracle/
chown R ora:dba sapdata*
chown R ora:dba origlog*
chown R ora:dba mirrlog*
9. Change the name of control files (cntrl.dbf) with new SID
10. Startup mount must work successfully.
Use command:
su ora
svrmgrl
connect internal;
startup mount;
11. Define new locations to database for data files and log files.
Use command:
su ora
svrmgrl
connect internal;
alter database rename file /old/file/name to /new/file/name;
12. Startup R/3 with startsap.
Use commands:
su - adm
startsap
13. If not start; see OSS note--> 8179 (grant connect to sapr3 identified by SAP)
14. Log on to SAP via SAP* user.
15. Run ST06 and set workbench organizer.
16. Install new license.
17. Change the spool server names on SAP system. (SPAD)
