  8.3.4 Renaming a Datafile in the Primary Database
  
  When you rename one or more datafiles in the primary database, the change is not propagated to the standby database. Therefore, if you want to rename the same datafiles on the standby database, you must manually make the equivalent modifications on the standby database because the modifications are not performed automatically, even if the STANDBY_FILE_MANAGEMENT initialization parameter is set to AUTO.
  
  The following steps describe how to rename a datafile in the primary database and manually propagate the changes to the standby database.
  
     1.
  
        To rename the datafile in the primary database, take the tablespace offline:
  
        SQL> ALTER TABLESPACE tbs_4 OFFLINE;
  
     2.
  
        Exit from the SQL prompt and issue an operating system command, such as the following UNIX mv command, to rename the datafile on the primary system:
  
        % mv /disk1/oracle/oradata/payroll/tbs_4.dbf
        /disk1/oracle/oradata/payroll/tbs_x.dbf
  
     3.
  
        Rename the datafile in the primary database and bring the tablespace back online:
  
        SQL> ALTER TABLESPACE tbs_4 RENAME DATAFILE      2> '/disk1/oracle/oradata/payroll/tbs_4.dbf'
          3>  TO '/disk1/oracle/oradata/payroll/tbs_x.dbf';
        SQL> ALTER TABLESPACE tbs_4 ONLINE;
  
     4.
  
        Connect to the standby database, query the V$ARCHIVED_LOG view to verify all of the archived redo log files are applied, and then stop Redo Apply:
  
        SQL> SELECT SEQUENCE#,APPLIED FROM V$ARCHIVED_LOG ORDER BY SEQUENCE#;
        SEQUENCE# APP
        --------- ---
        8 YES
        9 YES
        10 YES
        11 YES
        4 rows selected.
  
        SQL> ALTER DATABASE RECOVER MANAGED STANDBY DATABASE CANCEL;
  
     5.
  
        Shut down the standby database:
  
        SQL> SHUTDOWN;
  
     6.
  
        Rename the datafile at the standby site using an operating system command, such as the UNIX mv command:
  
        % mv /disk1/oracle/oradata/payroll/tbs_4.dbf /disk1/oracle/oradata/payroll/tbs_x.dbf
  
     7.
  
        Start and mount the standby database:
  
        SQL> STARTUP MOUNT;
  
     8.
  
        Rename the datafile in the standby control file. Note that the STANDBY_FILE_MANAGEMENT initialization parameter must be set to MANUAL.
  
        SQL> ALTER DATABASE RENAME FILE '/disk1/oracle/oradata/payroll/tbs_4.dbf'
          2> TO '/disk1/oracle/oradata/payroll/tbs_x.dbf';
  
     9.
  
        On the standby database, restart Redo Apply:
  
        SQL> ALTER DATABASE RECOVER MANAGED STANDBY DATABASE
          2> DISCONNECT FROM SESSION;
  
  If you do not rename the corresponding datafile at the standby system, and then try to refresh the standby database control file, the standby database will attempt to use the renamed datafile, but it will not find it. Consequently, you will see error messages similar to the following in the alert log:
  
  ORA-00283: recovery session canceled due to errors
  ORA-01157: cannot identify/lock datafile 4 - see DBWR trace file
  ORA-01110: datafile 4: '/Disk1/oracle/oradata/payroll/tbs_x.dbf'
  

  Hope that helps.

• How to move a segment in the SYSAUX tablespace data file

  Hello
  
  I had a problem with my tablespace SYSAUX growing due to the history of Stats being not properly purged (lots of hits and articles against this known issue). I have since corrected this problem and I did my SYSAUX tablespace so that it is now less than 3 GB. However, the data file unique original behind this tablespace is still 10 GB and I want to reduce again to below 6 GB.
  
  However as a suspect when I try to reduce the data return file I get ORA-03297 file contains data beyond the requested value of RESIZING.
  
  I checked the table dba_extents for this tablespace, which reveals there are approximately 765 segments over my desired fix of 6 GB.
  
  Q1. If there is only 1 or 2 segments above this mark of 6 GB, how would manually move their bottom?
  
  Q2. I gave have 765 segments above this 6 GB brand, what are the recommendations to achieve the mass movement required of these segments?
  
  Thank you
  Jim

  The Alter Table or Alter Index statement will pass all these types of segment?

  Lol some are special items.

  Here is what I make sure you test something you care to.

  And the double test. Frankly, I would like to change the least possible and if I didn't do it, I would avoid.
  It might be easily really much, much more trouble than its worth.

  LOBINDEX

  ALTER table move lob () store (tablespace );

  NESTED TABLE

  A nested table can be moved to a different tablespace only by moving his table containing storage target.
  (Move the parent table, which is only necessary.)

  PARTITON TABLE

  ALTER partitioned table move partition part_2 tablespace ;

  LOB SEGMENT

  ALTER TABLE owner.table_name MOVE LOB (column_name) STORE AS (nom_tablespace);

  CLUSTER

  I'm not sure.

  INDEX PARTITION

  example of

  ALTER INDEX SYS. I_STREAMS_APPLY_SPILL_MSGS_PT1 CHANGE DEFAULT USERS TABLESPACE ATTRIBUTES;

  PARTITION OF LOB

  ALTER table

  partition of moving lob () store as (tablespace );

• Tablespace, data file auto-extension

  Hi gurus!
  
  I'm new here, I have a dout.
  
  What you recommend me, generate a data file auto-étend or generate more data for a tablespace file?
  
  Is there a problem with the performance?
  
  Rigth now I a tablespace with a self-aggrandizing data file ' extends, with an increment of 10240KB, it of a table with a level of transaction gran space every day, allowed the size of increace?
  
  Thanks in advance

  879411, I'm not sure I understand everytihing say, but in general you want that data files are rarely extend to 100%. You do not want to set the next is large enough that the file would extend only rarely. You would balance against if at some point, you expect the items being supported in the tablespace to each stop growing or the rate of growth slows down significantly.

  Choose a file size which would become perhaps once a week might be a good size to start.

  At least the file extend the size should match the object to the extent that is required. In the case of a managed tablespace locally allocated by self, this could be 64 M.

• Loss of all control files and two independent of the system tablespace data files.

  Hello
  
  
  Loss of the controlfile and 2 data files: February 25, 2010... 15:00
  
  Database: in Archivelog mode
  
  Backup: controlfile and all (6) datafiles on February 20, 2010 and all archive logs are available up to the failure
  
  -Wanted to recover.

  Even if the controlfiles are restored from a backup, as long as the archive + online redo logs are available, you can make a FULL recovery.
  At the end of the recovery, an OPEN RESETLOGS would update the controlfile with correct information about SNA sequence # and headers of files.
  (Of course, the RESETLOGS would mean a new incarnation is created and log sequence numbers start from 1 - if you perform a backup as soon as possible after the RESETLOGS).
