Server Administration :: Removing A Tablespace And Its Associated Datafiles?
Jul 12, 2010
Due to improper documentations of a certain project, I need to drop a DEFAULT tablespace of a newly created instance including it's associated datafiles by using this command:
"DROP TABLESPACE <tablespace name> INCLUDING CONTENTS AND DATAFILES;"
The default tablespace name is QWER (qwer01.dbf) and I added 2 datafiles in it, re: OPD_SML01.dbf & EXYT_SML01.dbf.
Just noticed MR(media recovery lock ) in our database,further check showd all datafiles had this lock since our database was shutdown abortly but was startup gracefully.
What is best practice to change small disk D:? I am beginner with Oracle. 10g on W2008. 5 datafiles (all indexes,second data file, 2 undotabs)*.dbf (34;30;1;34;12 GB) is on D:. Part of tablespaces (1 data, 1 undo)has files on c:.
I. 1.Shutdown 2008 server. 2.Copy D: image with GHOST to USB, network. 3.Connect new D, create RAID. 4.Restore image to D. 5.Start 2008 server.
II. 1.Stop application. 2.CONNECT AS SYSDBA 3.SHUTDOWN NORMAL or (IMMEDIATE)? 4.Copy files *.dbf at OS level from d: to ... USB disk, network. 5.Shutdown 2008 server. 6.Change disks, create RAID in BIOS. 7.Start W2008. Is Oracle at this moment in SHUTDOWN mode? 8.Copy back *.dbf to new D: (with directory structure). 9.STARTUP Oracle.
Table D-7 shows a hierarchical file mapping of a sample OFA-compliant installation with two Oracle home directories and two databases. The database files are distributed across three mount points, /u02, /u03, and /u04. URL....
why three mount points (/u02, /u03, and /u04) for datafiles? don' understant this. isn't it better to store all datafiles in one mountpoint?
I have checked the space of my tablespaces/datafiles in my database. I have 8 GB space left in my database server. I cant add more hard-disk as there is no slot left. We r planning to buy a new server with latest config.
My question is, how can we know upto what size our database can increase and when a datafile need to be added in advance. Sometimes even though datafiles have space left,it shows errors abt extents cannot be extended. We have coalesce the tablespaces and added a new datafile.
I am facing an issue while rebuilding a DR (Physical Standby) site using RMAN.Rman is failing to restore all the datafiles to the stanby site.
There are 403 datafiles that should be restored among which after restoring 50-60 datafiles the channel is abruptly getting terminated.Please note this exercise is not new I have done this many times (once a year after a DR testing) and the same script is being used.The rcv file is as follows
/u03/oracle/admin/mpr/scripts/dataguard/configure_dr.rcv connect auxiliary sys/XXXX@YYY run { duplicate target database for standby nofilenamecheck dorecover; } exit CONFIGURE DEVICE TYPE DISK PARALLELISM 1 BACKUP TYPE TO BACKUPSET; configure_dr.rcv: END [code]....
The trace file says "krso_proc_add: Detected dead process 13828326; subsuming V$MANAGED_STANDBY slot INFO: krsr_rfs_atc: RFS processes are temporarily disallowed"
I have also started RMAN debug tracing and the trace is also scanned as it is huge.I have seen the following in the trace error 3015 signalled during compilation..I do not find any specific oracle error to check on .
The only change that happened is that the Primary production server has been moved to a new datacentre and after its move all the connections seems to be working fine.
We have lost some datafiles and some archivelogs. We have backup of whole database taken on Dec 20 and archivelogs until Dec 23.So we dont have 1 day worth of archivelogs which can lead to incomplete recovery.
Now question is do we need to restore all datafiles or only lost datafiles for incomplete recovery since we dont have all archivelogs ? lost datafiles belong to different tablespaces.
Datafiles which are still intact are with current SCN and we restore lost datafiles only and recover unitl our last available archivelog it will have different SCN. Will we be able to open database or we need to resotre whole database for this scenario?
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

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 need a PL/SQL stored procedure which will accept a datafile name as parameter and dynamically create and execute "alter tablespace" command to add this passed datafile dynamically.
1) I have created One tablespace "ABCD" and assigned one user on it "ABCD_AR". I made table through the user and made some transaction.
2) Then I have taken RMAN backup, which include backup of tablespace (ABCD) also.
List of Datafiles in backup set 10 File LV Type Ckp SCN Ckp Time Name ---- -- ---- ---------- --------- ---- 1 Full 997754 17-JUN-13 C:APPADMINISTRATORORADATATESTSYSTEM01.DBF 2 Full 997754 17-JUN-13 C:APPADMINISTRATORORADATATESTSYSAUX01.DBF 3 Full 997754 17-JUN-13 C:APPADMINISTRATORORADATATESTUNDOTBS01.DBF 4 Full 997754 17-JUN-13 C:APPADMINISTRATORORADATATESTUSERS01.DBF 5 Full 997754 17-JUN-13 C:DATAFABCD01.DBF
3) After taking Rman backup, I issued command - "Drop tablespace ABCD including contents and datafiles;"
4) When i issue "LIst backup" through RMAN, its shows blank for the particular tablespace datafile.
SQL> DROP TABLESPACE ABCD INCLUDING CONTENTS AND DATAFILES;
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.
Problem Description: There are five range partitioned tables which are partitioned by date,designed by previous DBA.Four tables are in one tablespace and one more table is in another tablespace.For every three months there are two tablespaces are created autamatically in new names for future dates.There is no scheduled job for this.How they are created?.This is our question.
In my database ,the size of the system tablespace is 1024M.now i found its free space is 477.875M.
SQL> SELECT TABLESPACE_NAME,SUM(BYTES)/1024/1024 M FROM DBA_FREE_SPACE where tablespace_name = 'SYSTEM' GROUP BY TABLESPACE_NAME ; TABLESPACE_NAME M --------------- ------- SYSTEM 477.875
In system tablespace ,the max size segment is IDL_UB1$,it is 167M
SQL> SELECT SEGMENT_NAME, SX || 'M' "Size" FROM (SELECT SEGMENT_NAME,SUM(BYTES)/1024/1024 SX FROM DBA_SEGMENTS WHERE TABLESPACE_NAME = 'SYSTEM' GROUP BY SEGMENT_NAME) WHERE SX > 100 ORDER BY SX DESC; SEGMENT_NAME Size ------------- ----- IDL_UB1$ 167M
My tablespace contains two datafiles dfile1.dbf and dfile2.dbf on D drive of my filesystem. Now i copied these dbf files on pasted it on a location in E drive. Now i want my tablespace to use dbf files pasted in new location.
Will i have to Alter Tablespace Add Datafile with Reuse clause
In My database rollback segment space is not releasing space even though, there is no transaction is using RBS. RBS tablespace size is around 70GB. Unfortunately still our environment is running in 9i due to application code
SQL> show parameter undo

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?
