I'm having difficulty with the syntax to change the uniform size of an existing tablespace. I haven't found much on it. Any help would be appreciated.
Thank you

Default Storage versus Uniform size at creating Tablespace

anybody can explain if those two concepts mean same? in my practice, i need to dump all data from 9i to 10g database, in 9i a tablespace created by :
CREATE TABLESPACE DATA_TS
DATAFILE '/opt/oracle/u01/data_04.dbf' SIZE 11M AUTOEXTEND ON NEXT 1024K MAXSIZE UNLIMITED
EXTENT MANAGEMENT DICTIONARY
LOGGING
DEFAULT STORAGE(INITIAL 112K
NEXT 112K
MINEXTENTS 1
MAXEXTENTS 1017
PCTINCREASE 0)
ONLINE
PERMANENT
SEGMENT SPACE MANAGEMENT MANUAL
so in 10g I created tblsp like:
CREATE TABLESPACE DATA_TS
DATAFILE '/opt/oracle/u10/data_04.dbf' SIZE 11M AUTOEXTEND ON NEXT 1024K MAXSIZE UNLIMITED
EXTENT MANAGEMENT LOCAL UNIFORM SIZE 112K
LOGGING
ONLINE
SEGMENT SPACE MANAGEMENT MANUAL
are they same?

Hi,
Two concepts are not same.
Check this link:
http://download-west.oracle.com/docs/cd/B10501_01/server.920/a96521/tspaces.htm
Starting with Oracle9i, the default for extent management when creating a tablespace is locally managed. However, you can explicitly specify that you want to create a dictionary-managed tablespace. For dictionary-managed tablespaces, Oracle updates the appropriate tables in the data dictionary whenever an extent is allocated, or freed for reuse.

Alter tablespace command problem (sql statement))

Hello,
I have a table space named t_space2.
I wanna add a datafile for this tablespace so I wrote on sql the following:
Alter tablespace t_space2
add datafile 'D:\DATA\cust.dat'
size 30 M;
it gives me the following message:
table space t_space2 doesn't exist!!!
the tablespace exsits on dba_tablespaces.
Thank u in advance
null

Hi,
the reason may be that one:
You created the tablespace with a command like that:
CREATE TABLESPACE "goofy"
DATAFILE 'E:\ORADB8I\ORADATA\WARPING\GOOFY_01.dbf' SIZE 5M REUSE
DEFAULT STORAGE ( INITIAL 80K NEXT 80K MINEXTENTS 1 MAXEXTENTS UNLIMITED PCTINCREASE 1 )Using the quotes, You've indicated to the DB to use the name exaclty as written, so in lower cases.
Because of that, every time You need to refere to the tablespace, but the same is for tables or column names, Youve to use the name "goofy" intead of goofy or GOOFY.
This is used to permit to the user, if it is necessary to the application, to use a field name that may be:
"Total Amount Field"
I believe that this is the rela reason.

Alter tablespace add datafile taking too much time

Hi All,
DB Version :10.2.0.1
OS Version: Windows Server 2003 32 Bit
When i am trying to add datafile into tablespace it takes lot of time approx 8 hours.but earlier it take approx 40 to 60 mins
When i check Alert log file i got the message:
ORA-604 signalled during: alter tablespace crbt add datafile
I check there is sufficent space in Disk as i need to add Datafile of 30G.
Syntax i am using is
ALTER TABLESPACE TEST
ADD DATAFILE 'C:\TEST02.DBF' SIZE 30G
Can anyone tell me exactly the reason for the same
Thanks in advance

Hi Aman,
The space is added sometime but most of the time i am getting this error

Alter tablespace RW on standby database

I work with Oracle8i for Solaris.
I've created a stanby database which is opened in read only.
Now, I need to use a temporary tablespace, so
I've tried :
"alter tablespace temp nologging read write;"
But, oracle answer me an ORA-16000 error (database open for read-only access).
So :
1) Is it possible to use a temporary tablespace in standby mode ?
2) How.
Thanks,
Philippe
null

Hello,
Since the table sizes is about 100GB , it takes time to move and rebuild the indexes and the end user application doesnot work if any of the index is unusable or not present.I think it will generate a lot of Archived logs, so it will be very heavy to manage and apply to your Standby.
If it's possible, it will be faster to put your Primary database in NOARCHIVELOG mode then, you make the Move and Rebuild.
Afterwards, you put again the Primary in ARCHIVELOG mode and take a good BACKUP of it.
Later, when nobody work on Standby, you recreate it.
Hope this help.
Best regards,
Jean-Valentin

[b]Resizing/Altering Tablespaces Oracle9i[/b]

1. I want to solve a performance problem by resizing the:
temporary tablespace
rollback tablespace
undo tablespace
using
Alter tablespace, by doubling the storage parameters.
Is this enough or should I resize the associated datafiles?
2. Is it better performance wise: to resize the datafiles, i.e doubling
capacity
OR
adding another datafile to the tablespace with the same capacity as
the first one.

Well U should add space in datafiles if datafiles are of smaller size and very soon they need to autoextend.
Storage parameters must be decided before making tablespace.
for ur second query i will suggest u to have different datafile on different disks

Hot backup : Rman vs. ALTER TABLESPACE...BEGIN BACKUP

Dear Experts,
I'm currently using the following statements
- ALTER TABLESPACE (...) BEGIN BACKUP
- host ocopy (...)
- ALTER TABLESPACE (...)END BACKUP state
I'm going for rman now but I've got 2 questions for those who did that in the past:
1/ Will rman reduce the size of my hotbackup ?
2/ Does the hot backup run faster using rman ?
Thanks.
Best Regards,
Jerome

1/ Will rman reduce the size of my hotbackup ? rman backup only those blocks which get accessed by oracle, means it doesn't copy the empty blocks as a part of backup as your OS copy command does. So yeah, the size of the backup will be smaller if there are huge datafiles but with comparably less data. Moreover if you are on 10g then you can use compressed backupset feature which will compress the backupsets.
2/ Does the hot backup run faster using rman ?
By using rman, there is no need to put every tablespace in backup mode, you can run the backup in parallel by allocating multiple channels, on 10g you can use block change tracking feature to speed up your incremental backups AND as explained in point 1 there is no need to copy the whole datafile. These all are the benefits of RMAN and I can't make a state statement that by all this the backup will run faster but will definitely go for it.

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 ;)

Enqueue while trying to alter tablespace

I try to run the "alter tablespace .... read only " command ,
through sqlplus (as sysdba) ,
but never get back to prompt .
instead when I run "select * From v$session_event where sid=XX"
I get an event named enqueue with large number in "total_waits" column and the same number in "total_timeout" column .
why do I have this lock ?
who else can lock the same object ?
I administer DWH project , with total size of 3.5 T , but the specified tablespace is only 325MB , no one runs a query againts this tablespace right now , and no one writes into tables that are built on that tablespace .
how can I monitor it and find out what causes the lock ?
I use oracle 9205 on UNIX AIX 5.3 64 bit .
Thanks .

please someone correct me if I'm wrong ,
but I've just entered the metalink site , and saw that it is a reported bug affecting versions 9.2.0.5 and 10.1.0.3 .
the bug is fixed in versions 9.2.0.7 and 10.2.0.1 , am I right ?
they are talking about SMON that holds TT enqueue and preventing alter temporary tablespace , mine , is not temporary tablespace , it is permanent tablespace ,
but I bumped into the same lock .

Its not possible online...
Perform below steps:
1. Move all the objects to some other tablespace.
2. Drop the tablespace and recreate with the desired storage option..
3. Move objects again to original tablespace
