Server Administration :: Move File System Datafile To ASM
Oct 23, 2012
I mistakenly added a datafile to a tablespace which is asm, however the datafile was created in a default location and not the asm location:
alter tablespace pdaiidata1 add datafile '<filename>' size 2048M;
What I should have done:
alter tablepsace <tablespace_name> add datafile '+DATA1' size 2048M;
Is there any way to move this filesystem datafile into the asm tablespace? In previous Oracle versions, I've taken a tablespace offline, moved a datafile, renamed it, then brought the tablespace back online. Can I do something similar here in this situation?

I want to remove a tablespace with it's datafile.
I've ran: DROP TABLESPACE x_tbs INCLUDING CONTENTS;
I've read(should have read it prior to action) [URL]tm
and I understand now that I should have stated "AND DATAFILES", However, too late now. the tablespace is removed, but the datafile x_tbs is still present in a folder of my OS.
Is it safe to manually remove it by deleting it from the operating system?

what is the Minimum datafile size required for creating a non-system tablespace?
I am trying to create a tablespace by giving the syntax like,
SQL> create tablespace t1
2 datafile '/home/data/t1.dbf' size 72k;
create tablespace t1
*
ERROR at line 1:
ORA-03214: File Size specified is smaller than minimum required
SQL> create tablespace t1
2 datafile '/home/data/t1.dbf' size 73k;
Tablespace created.
The blocksize for my database is 4096, as i have heard that the minimum size of the datafile is decided by blocksize, but i want to know that how it is calculated as by giving the above syntax the other values will be default. I am trying the syntax in oracle 9.2.0.1.0 version.

In normal days size of archives generated in a day is 14-15GB. But since yesterday morning, almost 150GB of archives have been generated and are still getting generated(200MB every 1-2 minutes).
There was a sudden reboot of server yesterday morning. At that time there was heavy load of transactions on database. Can it be a reason that smon is still doing recovery? (I am not sure on this). Also, Undo tablespace is increased from 18 GB to 50 GB since yesterday (autoextend on).
Now we are running out of space for archive file system (can't delete them also until they are transferred to DR) Size of redo log is 200MB. This database supports around 2500 users.
performance wise I don't see any hit. Also wait events are normal. (only few db file sequential read) finding the query/session which are causing this much huge amount of archives?

As part of an incremental backup I recover copies of the tablespaces. These by default are stored in the disk backup location diskgroup. Is it possible to move these copies to another disk group / location whilst still backing up to the default disk backup location diskgroup. I know how to do it with the main datafiles but not with the copies.
e.g.
Current situation:
Original Datafiles in +DATA
Backups in +FRA
Recovered Datafile copies in +FRA
New setup to be:
Original Datafiles in +DATA
Backups in +FRA
Recovered Datafile copies in +BACKUP

1) can we use a CSV file as a Data file in any format (fixed, delimited...) of Sql loader. I tried, but not succeeded.
2) if not then tell me the reason for it....
3) Also tell me is there any restriction on using the file format for a datafile?

I have oracle 10g running on Solaris with file system and some one created database files with same name but in different directories for example data01.dbf in two different directories, say /u01/oradata/data01.dbf and /u02/oradata/data01.dbf. Now, I want to find out the duplicate datafiles (data01.dbf in this case) sitting in different directories, is there anyway to find this out?

Is there a way to find out when a datafile for an undo tablespace with autoextend enabled actually extended? I've done a few tests, and nothing is written to the alert log or any trace file that I've found. I can't find any V$ or DBA view that will give me the history of a file's size.

We need to find when any datafile was resized ( if at all)in a tablespace. Actually, by noting the created date from v$datafile , we used to know the data growth in a tablespace. Now as the number of datafiles have increased, we want to resize them. This diagnostinc have to be done without changing/adding anything in DB.

I am using perl script to dynamically generate the control file.If I have data in the control file as well as in the datafile, how would i write the control file in that case. Is the below one correct?
load data
INFILE '*'
INFILE '/export/home/test/test.csv'
INSERT INTO TABLE EMP fields
terminated by "," optionally enclosed by '"'
trailing nullcols
( empno, empname, sal, deptno )
[code]....
Is there any way that if my control file contains half of the data and my data file contains the other half of the data can i club this data into a logical record in the control file to populate the DB?
My exact 2nd requirement is, my DB contains 5 cols and for 1 col the data is common(countryName) which i have to pass to the control file dynamically and the .csv file contains the data for the other four cols. How could i combine these in the ctrl file and populate the DB?
so if the DB contains CountryName, empid, ename, sal and dept..I will get the CountryName to the ctrl file and csv contains the data for empid, ename, sal and dept. How would i combine these data into a logical record and populate the DB?

This facility has one last 10g database and a very problematic tablespace and last datafile associated with it. The tablespace was set up with INITIAL_ EXTENT of 131,072 (128K) instead of the more 'normal' 4,194,304 (4M) and NEXT_EXTENT of 262,144 (256K) instead of 4,194,304 (4M).
More worryingly, the datafile has INCREMENT_BY set to 1 (8K) instead of 1,280 (10M) or 2,048 (16M).Has anyone ever updated sys.ts$.dflinit and sys.ts$. dflincr to modify the INITIAL_EXTENT and NEXT_EXTENT, and sys.file$.inc to modify the INCREMENT_BY?

I have one generic question about space management. I have one table with size of 1TB. This table stored in ORC1 tablespace. This tablespace contains 70 datafiles.
Since it's 10.2.0.4 database. I have dropped this table by using purge
drop table <<table_name>> purge;
Once table drop was completed. When I check the tablespace space it was 100% free but due to HWM was unable to resize the datafile from current size to small size. What was the reason behind this. Is there any process needs to follow when dropping big tables ? like instead of dropping the tables do I need to truncate first & then drop .
