To add a datafile

I have Hp ux 11i on rp3440 servers. we have database oracle 10g .our data base is on eva storage.now the size of tablespace 'USERS' is reached to 90%. so how can i add a datafile on running database. plz hepl me............

This is an example of howto resize the users tablespace;
first check the actual size of the users tablespace and its datafiles;
SQL> select tablespace_name,file_name,bytes /1024 /1024 from dba_data_files where tablespace_name ='USERS'
TABLESPACE_NAME FILE_NAME BYTES/1024/1024
USERS /u02/oradata/users01.dbf 5
In this case, only one datafile belongs to USERS tablespace and its size is 5 MB;
if you want to resize it to 10 MB then type
SQL> alter database datafile '/u02/oradata/users01.dbf' resize 10M;
Database altered.

Can't add new datafile into a table space?

Hi, Oraclers,
I am learning Oracle. I found one problem: I can't add new datafile to an existing
table space. I tried to add via OEM and SQLPlus. None of them works.
I can see that the datafile, say ras01.dbf, is in my hard drive. But I can't see
it via OEM datafile.
Also, this datafile creating procedure has never stopped. In SQLPlus, after I
submitte ths statement, after 7 days, this sql statement is still running. The
same thing happened in OEM.
The sql statement is:
ALTER TABLESPACE "RASBLK"
ADD
DATAFILE
'H:\ORACLE\PRODUCT\10.1.0\ORADATA\NMDATA\RAKBLK35.DBF' SIZE
26214400K REUSE AUTOEXTEND
ON NEXT 2048M MAXSIZE 30720M
Oracle is 10g V10.1.0.2.0
os is Window Server 2003 Service Pack 1.
What's the problem?
Thanks,

so you have definitely tried to use a Winlows Server with NTFS for a 1TB++ Database ?
I never heard of that and I wouldn't even dare to dream of that, but as stated above theoretically (that is: according to MS) this should work.
But surely your process has crossed some internal limitations, at least that is what it looks like.
I guess you must go to your %ORACLE_BASE%\admin\%SID%\bdump or udump directories to eventually find a trace file there.
recommendation is: move to some kind of bigger system (Solaris,AIX).

Increase the Oracle datafile size or add another datafile

Someone please explain,
Is it better to increase the Oracle datafile size or add another datafile to increase the Oracle tablespace size?
Thanks in advance

The decision must also includes:
- the max size of a file in your OS and/or file system
- how you perform your backup and recovery (eg:do you need to change the file list)
- how many disks are available and how they are presented to the OS (raw, LVM, striped, ASM, etc.)
- how many IO channels are available and whether you can balance IO across them
Personal default is to grow a file to the largest size permitted by OS unless there is a compelling reason otherwise. That fits nicely with the concept of BIGFILE tablespaces (which have their own issues, especially in backup/recovery)

Resize datafile or add new datafile which is good?

Hi all
we have 80 GB database size and only two tablespace have space around 60 Gb
these two tablespace have one database each around 30 gb so
My question is it good to resize current datafile or
It it good to add new datafile ?

Your question is which is "best"; add datafile or resize right? If yes, then I think below links will answer you :
http://www.freelists.org/post/oracle-l/Datafile-size-Is-bigger-better,9
datafile and size
Bigfile or smallfile tablespace?
Just go through these link. I am sure answer in it.

How to add a datafile in the temp tablespace

how i can add a datafile in the temp tablespace.
becuase i am getting tyhe following error
SQL> select aa.question_desc,a.answer_desc from answer a ,
2 (select * from question_t where rownum <=100 order by dbms_random.random) aa
3 where a.question_id = aa.question_id
4 /
select aa.question_desc,a.answer_desc from answer a ,
ERROR at line 1:
ORA-01652: unable to extend temp segment by 256 in tablespace TEMP

select * from question_t where rownum <=100 order by dbms_random.random After all the discussion about random select a random generated number... why don't you go for one of the suggestion like : 
select *
from (select * from question_t order by dbms_random.random)
where rownum <=100 The result is different. 
In your query, you take 100 rows and order randomly, in the second query, order randomly, and take 100 first rows... 
As you can see above, with your last query, output row are always same, but in different order : 
SCOTT@demo102> select ename from emp where rownum<=5 order by dbms_random.random;

Add new datafile to logical standby database but not in primary

Hi,
Is it ok to add a new datafile to the SYSAUX tablespace on the logical standby database but not on primary? We are running out of disk space on the partition where SYSAUX01.dbf resides so we want to add a new SYSAUX02.dbf in another partition which has space. but this will only be on the logical standby not on primary, there is still lots of space in primary. standby_file_management is MANUAL and this is LOGICAL STANDBY not PHYSICAL.
Is this possible or where there be any issues?
Thanks.

Logical Standby can differ from Primary, it can have extra tablespaces, datafiles, tables, indexes, users ...

Add temporary datafiles after creating standby database

I used data guard manager to create standby database and it went fine. Before finish, system pop up a window and says,
"The data guard configuration has been created in a disabled state. It must be enabled using the Enable option in the configuration menu. Pior to ebaling the configuration, please verify the following:
The Primary database contains temporary datafiles. The files will not be duplicated in the new standby database. You must manually recreate the temporary files on the standby node by adding them to their respective tablespaces in the standby database after creation process in complete."
The problem is, in the standby database, how do I add tempfile without open the standby database? the documentation is very unclear...

Thanks for the reply and the useful link. I had followed the instructions when creating the standby database, although under database options there is a difference between the OEM version we are using and the version shown, whereby the 'RMAN backup location' option has been replaced with 'working directory location'.
Just found the following and am guessing this is the issue.
NFS mounts established within a zone are local to that zone. The mounts cannot be accessed from other zones, including the global zone.
I suspect I will need to copy the backup pieces onto the local server in order to create the standby database using OEM. Not something I was expecting to have to do as copying will take a long time due to the size of the backup, but unless anyone else can shed any light on the reason for the initial error
RMAN Backup Location - The specified RMAN backup is invalid. Could not identify controlfile from the backup
then I guess this is the only way forward.

JP

Question about ALTER TABLESPACE add/drop datafile

Good afternoon,
As an exercise, I created a tablespace STORETABS and added a datafile to it using the command:
SQL> alter tablespace storetabs add datafile 'e:/storetabs3.dbf' size 50M;This step succeeded. A new file was created in the root of e: as expected.
Following that command, I issued:
SQL> alter tablespace storetabs drop datafile 'e:/storetabs3.dbf';
Tablespace altered.The command succeeded. However, the file *'e:/storetabs3.dbf'* was not removed. After re-reading the documentation found at http://download.oracle.com/docs/cd/B28359_01/server.111/b28286/statements_3002.htm, I get the impression that removing the O/S file itself is something that always needs to be done manually.
The question: Am I correct that there is no option to cause the "alter tablespace <tablespace> drop datafile <datafilename>" to delete the O/S file ? In other words, must the O/S file always be manually deleted as a separate step ?
Thank you for your help,
John.

I believe in windows directory paths used backslash and not forward slash.
You can argue why oracle does not give error, either while creating or while dropping ;)

Do we need to add new datafile.

There is one and only one datafile in my database. Now its size reached 3.6 GB. I already set it as Autoextend.
At this stage, do we need to add one more datafile ?

That depends...
Would having multiple files allow you to spread I/O over more spindles?
In the event of a disaster, how quickly can you restore a 3.6 GB file? If your data files were 2 GB, how would that affect the time it would take to recover from the loss of a data file?
Does your operating system have a limit on the size of a single file?
Personally, I would tend perfer a few 1 - 2 GB data files to a single large (and growing) file, but there may be no benefits to this in your environment.

Add Datafile in Logical Standby Database

Hi,
I have add one datafile in our primary RAC DB. We had logical standby database with file management is equal to manual. Both the primary RAC and logical standby db have the different storage structure. When the archive applied on the logical standby database its throws the error " error in creating datafile 'path'";
Would appreciate if come to know the steps to add the datafile in this kind of environment. and how can i overcome from this problem now except skip transaction for that ddl.
Thanks in advance.
Dewan

When the archive applied on the logical standby database its throws the error " error in creating datafile 'path'";Can you post the error message with the number.
From Manual..
8.3.1.2 Adding a Tablespace and a Datafile When STANDBY_FILE_MANAGEMENT Is Set to MANUAL
The following example shows the steps required to add a new datafile to the primary and standby database when the STANDBY_FILE_MANAGEMENT initialization parameter is set to MANUAL. You must set the STANDBY_FILE_MANAGEMENT initialization parameter to MANUAL when the standby datafiles reside on raw devices.
Add a new tablespace to the primary database:
SQL> CREATE TABLESPACE new_ts DATAFILE '/disk1/oracle/oradata/payroll/t_db2.dbf'
2> SIZE 1m AUTOEXTEND ON MAXSIZE UNLIMITED;
Verify the new datafile was added to the primary database:
SQL> SELECT NAME FROM V$DATAFILE;
NAME
/disk1/oracle/oradata/payroll/t_db1.dbf
/disk1/oracle/oradata/payroll/t_db2.dbf
Perform the following steps to copy the tablespace to a remote standby location:
Place the new tablespace offline:
SQL> ALTER TABLESPACE new_ts OFFLINE;
Copy the new tablespace to a local temporary location using an operating system utility copy command. Copying the files to a temporary location will reduce the amount of time the tablespace must remain offline. The following example copies the tablespace using the UNIX cp command:
% cp /disk1/oracle/oradata/payroll/t_db2.dbf
/disk1/oracle/oradata/payroll/s2t_db2.dbf
Place the new tablespace back online:
SQL> ALTER TABLESPACE new_ts ONLINE;
Copy the local copy of the tablespace to a remote standby location using an operating system utility command. The following example uses the UNIX rcp command:
%rcp /disk1/oracle/oradata/payroll/s2t_db2.dbf standby_location
Archive the current online redo log file on the primary database so it will get transmitted to the standby database:
SQL> ALTER SYSTEM ARCHIVE LOG CURRENT;
Use the following query to make sure that Redo Apply is running. If the MRP or MRP0 process is returned, Redo Apply is being performed.
SQL> SELECT PROCESS, STATUS FROM V$MANAGED_STANDBY;
Verify the datafile was added to the standby database after the archived redo log file was applied to the standby database:
SQL> SELECT NAME FROM V$DATAFILE;
NAME
/disk1/oracle/oradata/payroll/s2t_db1.dbf
/disk1/oracle/oradata/payroll/s2t_db2.dbf

Add a new datafile to the standby database

Hi,
i have a standby database in recovery managed mode.
Now i must add a new datafile on the production database and i would like
to know how i realized adding the new datafile on the stanby database.
is it right when i do the follow steps?
Before i add a datafile to the primary database,
cancel the recovery on the standby database.
-> add the new datafile on the primary database
after all archived redo logs have been applied, cancel managed recovery:
alter database recover managed standby database cancel;
startup nomount
alter database mount standby database;than
ALTER DATABASE CREATE DATAFILE '/oracle/DB1/db1_9/data9' as '/oracle/DB1/db1_9/data9';
alter database recover managed standby database disconnect;Thanks

8.4.1.1 Adding a Tablespace and a Datafile When STANDBY_FILE_MANAGEMENT Is Set to AUTO

ADD DATAFILE in ASM

Hello
How can I add a datafile in a RAC database with ASM?
The filename are create by ASM are like this
'+DATA/csoprd1a/datafile/aalarge.615.594210853'
where aalarge.615.594210853' is generated by ASM
thanks

Hello Daljit,
I already have this file, and I want to add another one and yes, I'm confused with the numbers, because , they are generated by ASM, so how can I do?
There is an Instance ASM, is there that I must add the datafile?

Can I add datafile bigger then 2GB

Hi all,
Can I add datafile bigger then 2GB (on the raw device) to the tablespace ?
I get err:
ORA-01119 : error in creating database file '/opt/DISK/data02'
ORA-27042 : not enought space on raw partition to fullfill request
Aditional information : 1
And
partition has size 4096543 kB
when I use partition with size 2GB it is Ok.
Is it limitation by Linux ?
I have linux 7.1
and oracle 8.1.7
What can I do ?
thanks

If you want to use raw devices with linux you have to use the utility 'raw' to map the device. You could also use the Logical Volume Manager (or both)

Hi Manu,
Oracle 8.1 -> desupported
Windows 2000 -> desupported
SAPDBA -> not maintained anymore
You're running pretty outdated software there...
Anyhow, yes you can use SAPDBA to add a datafile.
Just start SAPDBA.
You'll get a menu then, similar to this:
         SAPDBA V6.20 - SAP Database Administration - on WIN NT 5.1
                    ORACLE version: 9.2.0.8.0

          b - Instance information         i - Backup offline redo logs

          f - Archive mode                 m - User and security
          q - Quit
          Please select ==>
Choose "c . Tablespace administration" and "f - Alter   tablespace add data/temp file" in the following menu screen.
That should be easy enough.
