How to move all the datafiles, redo logs, tempfiles, undo datafile and controlfiles in a database in 11g/12c

How to move all the datafiles, redo logs, tempfiles, undo datafile and controlfiles in a database in 11g/12c

There are times when you need to move the whole oracle database to another location which includes moving all datafiles (system, undo, sysaux and other datafiles), redo logs, temp files and controlfiles.

1. Moving all datafiles expect system datafiles
2. Moving oracle temp datafile
3. Moving oracle undo tablespace/datafile 
4. Moving oracle system datafiles
5. Moving oracle redo log files
6. Moving oracle controlfiles

1-Moving all datafiles expect system datafiles:

SQL> select files.tablespace_name, files.file_name
  2  from
  3  (select file_id, file_name, tablespace_name, bytes/1024/1024 mb, autoextensible,
  4  decode(autoextensible,'NO',bytes/1024/1024,decode(sign(maxbytes-bytes),-1,bytes/1024/1024,maxbytes/1024/1024)) maxmb
  5  from dba_data_files) files,
  6  (select file_id, sum(bytes)/1024/1024 freemb
  7  from dba_free_space
  8  group by file_id) free
 9  where files.file_id = free.file_id (+)
 10  and files.file_name like '%&Fname%'
 11  order by 1,2;
Enter value for fname:
old  10: and files.file_name like '%&Fname%'
new  10: and files.file_name like '%%'

All the files are moved to new directory

12C datafile rename :

Starting with Oracle 12.1, you can now use the command ALTER DATABASE MOVE DATAFILE in order to rename, relocate, or copy a datafile when the datafiles or the database are online. One step only is required for any of these actions and the database remains entirely available in read and write for users, without any data loss.

You should however be aware of some rules:

• By default, Oracle automatically deletes old data file after moving them and prevents the user from overwriting an existing file.
• When you move a data file, Oracle first makes a copy of the datafile. Then, when the file is successfully copied, pointers to the datafile are updated and the old file is removed from the file system. This is why the operation requires twice the size of the files to be copied as free space.

Let’s have a look at some examples for the renaming or relocating of a datafile:

1) Renaming a datafile

SQL> ALTER DATABASE MOVE DATAFILE '/u01/oradata/DBTEST/demo1.dbf' TO

'/u01/oradata/DBTEST/demo01.dbf';

SQL> ALTER DATABASE MOVE DATAFILE '/u01/oradata/DBTEST/demo01.dbf'

TO '/u02/oradata/DBTEST/demo01.dbf';

2) Relocating a datafile

The available options are:

• KEEP: to keep the old datafile, used to make a copy of the file. Note that the pointer will be updated to the new file,the  old file only remains as unused on the filesystem. Note that on Windows, independently of the fact that the KEEP option is used or not, the old data file is not automatically deleted by Oracle. The user has to delete it manually after the copy is successfully performed.
• SQL> ALTER DATABASE MOVE DATAFILE '/u01/oradata/DBTEST/demo01.dbf' TO '/u02/oradata/DBTEST/demo01.dbf'

 REUSE: to overwrite an existing file.

• SQL> ALTER DATABASE MOVE DATAFILE '/u01/oradata/DBTEST/demo01.dbf' TO '/u02/oradata/DBTEST/demo01.dbf' reuse;

Moving a datafile online works in both ARCHIVE and NO ARCHIVE modes. You have no option to enable in order to use this feature, which is great. It does not work with an OFFLINE datafile.
On the backup & recovery side, a flashback database does not revert the operation. A datafile is definitively moved. But after moving a datafile, like for any other operation on the database structure, you will have to perform a new full backup of the database. Otherwise, you will have to move the datafile(s) back before being able to restore your database…
Finally, some files like temporary files, redo log files, and control files cannot be moved using this command, which is very helpful but can still be improved…
