Server Administration :: Trying To Change Tablespace And Datafile Properties On Fly
Aug 21, 2011
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 a tablespace which contains 121 datafile(max limit reached) as a dba what we have to do?
creating a new tablespace with a datafile and assign the users to the current tablespace which i created now.iif the above process is correct,after some time the tablespace which was filled up got freed up.now can i give the access to the users previous (i.e. freed up tablespace) and current tablespaces
Erroneously created datafile, re: "/path/../large_rbs_03.dbf" was created under the SYSTEM tablespace which is supposedly be in the LARGE_RBS tablespace.
How do I make the said datafile be under LARGE_RBS?
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?
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.

My os version is

My database is OLP system.
My question is what are the advantages and disadvantages having one single tablespace versus multiple tablespace?
Easy to maintain when you have single tablespace. but hard to track the IO issues if you have one single tablespace.
I can not drop datafile in a tablespace, how can i do?
SQL> Alter Database Datafile '/u02/app/oracle/oradata/oracl/hxl06.dbf' Offline 2 3 /
Database altered.
SQL> Alter Tablespace tps_hxl Drop Datafile '/u02/app/oracle/oradata/oracl/hxl06.dbf'; 2 Alter Tablespace tps_hxl * ERROR at line 1: ORA-03264: cannot drop offline datafile of locally managed tablespace
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?
Today i am facing an error when going to rezise the datafile its fixed size is 19000M abut after truncating all tables it is 112M, but when i am going to resize its datafile to 500M its get me an error ora-03297 file contain used data beyond requested size values.
I have done the same before a week without any error.But this time i got the error
I have a database of branch A whose files are located in E: Drive. I want to download it in branch B.I placed all the files of Branch A in D: Drive of Branch B. When i start the database i was getting controlfle error. I made required corrections in initorcl.ora. Now when i start the Database,its mounted, but I am getting ORA-01157: Cannot identify datafile 1. I tried to rename the file, but the "alter database rename file1 to file2;" option is not working.
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 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 need to resize my datafile as i have allocated more space and need to reduce ( i.e.data load completed now). my tablespace is having 11.74 gb free space now. it has 3 datafile.

[code]....
in TOAD, we have an option, that is "Minimum size" button against each datafile.. Need the SQL which is running behind when we press this button from TOAD ?
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 .
I have one database which is recently upgraded from oracle 8.1.5 to oracle 10.2.0.4.The database is having around 300 tablespace and total size of the database is 1.5 TB.
The database was created in oracle 8i and all the teblespace were DMT(Dictionary Managed Tablespace) .Usually after up gradation all the tablespace are in DMT mode. Now my requirement is to convert all the tablespace into LMT (Locally Managed Tablespace) so that I can AVAIL ALL THE FEATURES OF LMT.
This database is a mission critical database and very less downtime can be allowed.
I have a small problem, i will try to explain it, My tablespaces are Automatically extend datafile when full (AUTOEXTEND). It had checked "autoextend ON" checkbox.
What I need to know is, when happened that autoextend accion(day/hour), is it possible?.
I need to change data file path, and i got some document also but one thing confusing me, we need to offline the Tablespace, so my concern is all the table space like system, sys, user, temp etc. need to offline and then alter the database?
How datafile is created with 640 file permission by oracle software.(I know for security reasons it is created with 640 permission)
example: -rw-r----- 1 orasd dba 104865792 Mar 15 01:17 users01.dbf
I want to change the datafile permission as below. how to change the default value of the datafiles permission from (640) to (644) internally while creating the datafile from oracle side.
example: -rw-r--r-- 1 orasd dba 104865792 Mar 15 01:17 users01.dbf
Datafile name is +DISK_GROUP_1/oratst1/datafile/system.1122.764387443
displayed for the SYSTEM tablespace in dba_data_files.Infact, datafile name starts with +DISK_GROUP_1 for tablesspaces. Where is the reference to +DISK_GROUP_1.
What file name should I use to resize or to add new datafile to a tablespace?
