Why was tablespace SA offline in the first place?
What did you do with /flash_recovery/flash_recovery_area/SA/archivelog/2013_07_01/o1_mf_1_35_%u_.arc that the recovery could not find it?
What version (to 4 decimals) and edition (Enterprise, Standard, Standard One) is your database?

ALTER TABLESPACE "USERS" OFFLINE NORMAL; takes a checkpoint

I have an Oracle 10g database. I am trying to go back to a state when I created a physical copy of datafiles in the USERS tablespace. I use the procedure described in http://www.stanford.edu/dept/itss/docs/oracle/10g/server.101/b10734/osrecov.htm#1007495 to bring the files from a backup directory to the datafiles directory.
The commands I issue are:
ALTER TABLESPACE "USERS" OFFLINE NORMAL;
--copy physical datafiles from backup
ALTER DATABASE RECOVER TABLESPACE "USERS";
ALTER TABLESPACE "USERS" ONLINE;
I was expecting to see data from my old backup files, but it turnes out that OFFLINE NORMAL takes a checkpoint and restores the latest content.
I tried to use OFFLINE IMMEDIATE, but I cannot do it because my database is in NOARCHIVELOG mode.
Is there another simple way to bring data back from those datafiles?

your database is in the no archive log mode right... if the backups contain 1000 records and the current content in the tablespace 100 records...
then the only thing that you can do is if u have a complete database backup that you have taken at the time containing 1000 records.
i think you can use these backups as the database is in the noarchivelog mode. build an auxiliary instance restore all the data files control files and the startup to mount stage create the redo log file and then open the database.
export the table containing the 1000 records and then reimport into the current database..
i think that this procedure might work...

Tablespace offline / online.

Hi All,

Amit.

Hallo,
offlining a tablespace makes the tablespace unvailable to users but leaves ORACLE update the datafiles' header which belongs to the tablespace with important synchronization information. Plus during startup ORACLE checks if control file SCN matches offlined tablespace datafiles' headers.
That's why alert logs that messages..

ALTER TABLESPACE X RENAME TO Y

Hi all!
I want to know if i can apply an "alter tablespace rename to" sentence without stop the normal activity off the database or it's necessary stop the users access to the affected tablespace.
Thanks folks!!
Jordi

Actually there should be no issues with performance as
When you rename a tablespace the database updates all references to the tablespace name in the data dictionary, control file, and (online) datafile headers. The database does not change the tablespace ID so if this tablespace were, for example, the default tablespace for a user, then the renamed tablespace would show as the default tablespace for the user in the DBA_USERS view.
so there are no inserts or physical data move going on. Just all references are updated.

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.

Demerits of alter tablespace begin backup on 10.2.0.4

Hi,
What are the demerits of putting a tablespace in hot backup mode. I know that it generates additional data in redo logs. But, does DBWR and LGWR performance is also impacted? Does database writer throughput reduce leading to free buffer waits? Are these wait events common - free buffer waits and log file sync waits when tablespace is in hot backup mode? Please clarify.
Thanks,
Madhav

Those wait events would be symptoms of the increased I/O and higher I/O Wait/Response times.
There is obviously more Redo, so LGWR has more to write.
DBWR performance is probably being constrained by the I/O.
Note that it isn't just the ALTER TABLESPACE BEGIN BACKUP that is the cause. It is also the backup itself -- whether you are using cp or cpio or tar or any other method to copy datafiles to disk or to tape or to a remote server / tape library. The backup is reading from the same datafiles that DBWR is writing to and, if it is writing the backup to local disks, it is also introducing additional write I/O.

How to alter tablespace add in pdb from cdb root

Hi Experts,
Is there a way to run the "alter tablespace xx add tempfile ..." command in root cdb while the tablespace xx belongs to a pdb. Is it possible to do it without login or change session to pdb? Thanks.

Krishna-Oracle wrote:

You are confusing logging to PDB with setting PDB as current container. These are two completely different actions. Create common user:

Informations about 'alter tablespace ... coalesce'

Hi,
I'm quite new relatively to the DBA functions. I have an Oracle 8i database on a RedHat Linux server.
I've examined my tablespaces and I found that many of my tablespaces have the pctincrease=0. In this case the process SMON don't join the adjacent free extents so I have a lot of free extents but only few of them are coalesced.
I thought to coalesce them with the command 'alter tablespace nametablespace coalesce', but I don't know very much this command. I'd like to know more informations about it, above all if I can launch it when my users are working on the database or if it's better to stop the listener and to do a backup before to launch it (among the tablespace that I need to coalesce I have also the Temp tablespace).
In other words: is the alter tablespace coalesce an harmless command or I need to take some precutions ? And Where I can find more informations about this command ?
Thanks
Marco

You can find more information about the command by reading the manual.
Coalescing tablespaces is a relatively harmless command. You can run it while users are on the system. They might experience a momentary slowdown, but probably not. All the command does is delete and update entries in an Oracle internal table (FET$ if anyone cares). Coalesce will do nothing if there are no adjacent blocks of free space to coalesce.
You do not want to coalesce the freespace in your temp tablespace. Oracle manages this internally, and it is more efficient to have a lot of fragments for temp. It saves a lot of recursive sql when a new extent is needed for a sort.
In the other tablespaces, if the blocks of free space are relatively large, then coalescing will not really gain anything. If your fragments are small, and your segments are frequently allocating new extents (which in itself is a problem), then you may gain a little performance by manually coalescing the tablespace. However, Oracle will coalesce free space if required to get enough space to allocate a new extent.
If you want to see if coalescing will do anything, you can use:
SELECT tablespace_name,file_id,block_id,block_id + blocks next_free
FROM dba_free_space
ORDER BY 1,2,3Then check if next_free in the previous row is the same as block_id in the current row.

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 ;)
