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
Dear all,

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 );

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.

Undo tablespace/data files
Oracle 9i

In production, we get the undo data files:

This table has 90 million records

I estimated the size of the table:

We need to insert records to the new table 55 million. When insert, I want to just run insert in... . Select statement once, only to commit only once.
do you think that undo tablespace is large enough to contain 55 million records based on the data above undo files?

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).

Can system table space cause multiple data files in several places?

Hi experts,
Our current system has a partition to keep the system tablespace data files, but I assumed that the partition is wrongly estimated and the size was maintained only 2 GB. Now the partition's got full and it seems no way to increase the partition from the OS. The only option I have is to create the new data for system tablespace file in another free partition. Is this possible? I have to consider all things important before doing this? Also can I create new data with the regular create command file or need to do something special for system tablespace?
Thanks in advance

Yes, you can create two data files for system tablespace into two partitions.

To reduce the space in the system tablespace - you should check what are segments that occupy the space in the system tablespace.

To get the examples if you have the Audit DB - then you can move the table to tablespace someother depending on availability.

Why the Media recovery is necessary once a data file is brought back to fashion online?

Hi DBAs,
Consider the following scenario:

Offline data file:
08:09:38 coredev > select status, name from v$ datafile where name like '% UNDO4% ';
NAME OF THE STATE
------- ----------------------------------------------------------------------
F:\ORACLE\ORADATA\CD\UNDO4 ONLINE. DBF
08:09:47 coredev > alter database datafile ' F:\ORACLE\ORADATA\CD\UNDO4. DBF' offline;
Database altered.
08:09:58 coredev > select status, name from v$ datafile where name like '% UNDO4% ';
NAME OF THE STATE
------- ----------------------------------------------------------------------
RETRIEVE F:\ORACLE\ORADATA\CD\UNDO4. DBF
08:10:02 coredev > select * from v$ tablespace where name = "UNDO";
ENC FLA BIG TS # NAME INC.
---------- ------------------------------ --- --- --- ---
UNDO 33 YES NO YES
Data file online:
08:10:53 coredev > alter database datafile ' F:\ORACLE\ORADATA\CD\UNDO4. DBF' online;
ALTER database datafile ' F:\ORACLE\ORADATA\CD\UNDO4. DBF' online
*
ERROR on line 1:
ORA-01113: file 21 needs media recovery
ORA-01110: data file 21: ' F:\ORACLE\ORADATA\CD\UNDO4. DBF'
08:11:04 coredev > recover datafile ' F:\ORACLE\ORADATA\CD\UNDO4. DBF';
Complete media recovery.
08:11:13 coredev > alter database datafile ' F:\ORACLE\ORADATA\CD\UNDO4. DBF' online;
Database altered.
08:11:49 coredev > select status, name from v$ datafile where name like '% UNDO4% ';
NAME OF THE STATE
------- ----------------------------------------------------------------------
F:\ORACLE\ORADATA\CD\UNDO4 ONLINE. DBF
Now my doubt is:
1.Pourquoi Media recovery is necessary once a data file brought to online from offline mode?
2. why DB not open and throws the error message after brining online of offline?
3. Why is he asking for recovery of the media?
I'm very confused...!
Kind regards
Ritu

In order to make the UNDO4 data file. Coherent DBF with other UNDO tablespace data files, when you bring it from OFFLINE to ONLINE, the changes that happened during the period offline needs to be applied to this data file hence it is requires media recovery.

It is directed by my understanding.

data file
If I use several for a tablespace data files, such as

create tablespace TEST
DataFile ' / oradata/ts_01.dbf ' size 32G,.
' / oradata/ts_02.dbf ' size 32G

How ORACLE will write to these files? I mean, he'll write a whole first, after it is full, then write to another? Or he's going to write to both of them, even though none of them are complete?

Thank you
