  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 reduce the temp tablespace data file

• Users tablespace - data file is 24.5 GB, only 1.2 GB used - what should I do?

  Hi all
  
  In my database I have users tablespace and its data file is users01.dbf. File size is 24.5 GB, but the data used are of 1.2 GB. I got this information from OEM, see image below:
  https://picasaweb.Google.com/100555146235257804098/Oracle_a1#5759303022195932370
  
  How I can free unused space of 23GB?
  
  Just to let you know to my knowledge, I am a developer of report OBI.
  
  Thank you!

  >
  I executed the script sql on your link http://www.oracle-ckpt.com/how-to-shrink-datafiles-adjusting-hwm/

  It gives only 7 GB. If I can save only 7 GB so it will not help me. This is the maximum possible savings, you can do.

  Do you mean if I load 20 GB of data now in the post above, the database uses the current data file to increase the size of the file? Or it adds to the size of the file, that is to say 25 + 20 = 45 GB?

  It seems CanGrow is enabled for the USERS tablespace: CANGROW - YES

  If it uses the size of the file, then I can deal with the current structure. If we add to the file so I can't move forward.

  Your data file already occupied 23 GB, if you load another 20 GB of data. Of course, it can take another 20 GB, if all 23 GB already existing aid. Have you talked about the link that is mentioned by Sir Jonathan Lewis?

• 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 );

  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).

• Data files

  Hi all
  IM new to oracle. I had a situation where I have two under USERS tablespace data files. Question is former datafile that users01.dbf has enough space to use, without checking this correctly, I added a data file called another USERS02.dbf extension and 100 MB. Now USERS02.dbf in use I want to drop this USERS02.dbf and use USERS01.dbf. What is the recommended way to do this?
  
  
  Thanks in advance.

  Salvation;

  I agree with EdStevens, you don't need to remove your dbf, there will not be a problem for you.

• growth of data files

  Hello
  
  11 GR 2, OS is not serious, the DSO is excluded in this case - only FS
  
  I wonder what the algorithm behind the growth of the data files that belong to a tablespace, but for example for performance reasons, are placed on 2 different physical volumes.
  
  Do you know if the Oracle Server always takes advantage of spread of these files?
  
  What happens if we only have one huge table? -It spreads extended this tables consistently in these 2 data files?
  
  example:
  my_huge_table is located in the USERS tablespace which consists of 2 data files:
  e:\users1.dbf
  f:\users2.dbf
  
  My observation is that it is not expected that users evaluations1 is filled and using the file mobiles2 in parallel. However I don't know if it is reliable where performance is concerned. Please share your verified knowledge.

  When you add a second data file to a tablespace after segments have already allocated punctuated in the first data file - these extensions will remain in the first data file - there is no measure of rebalancing mechanism on this layer. The new data file will then prefer to allocate extensions, if, so sooner or later, the two data files will have a fill. This behavior is independent of the type of storage to that of data files.

  Kind regards

  Thank you

  Another way try this,

  1 put the tablespace that holds the database without name begin backup mode.

  SQL > alter tablespace mytbs begin backup;

  2 copy the missing data (copy of the OS) file to the location of the files of pending data.

  3. run the end backup command.

  SQL > alter tablespace mytbs end backup;

  4. create a controlfile for the use of the database pending,

  SQL > alter database create standby controlfile as ' / D:/oracle/stdcontrol.ctl';

  5. move the alos for standby server.

  In the standby mode,

  1 cancel the recovery mode.
  2 stop and change the controlfile.
  3. start the day before db in the editing phase.
  4 restore database pending.

  Thank you
