View 1 RepliesDue 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.
Do I have to do it online or offline?
Can we add a datafile mapped to a shared network drive in windows server.

my system01.dbf size is 6gb
i want reduce from 6gb to 2gb
I am looking for a script to find the tbs usage including datafiles. Tablespaces Datafile Size Used Free Used% Free% Max MB
Need all the data in MB and all the datafile space in every tablespace.I have searched internet,but couldn't find this type of format.
One of our solaris machines is running Oracle 8.0.3
A table reached the 2 Gb size and oracle failed due to the operating system file size limitation.
The information in the table is not relevant and can be deleted, but the table contains a lot of indexes.
I would like to know the best procedure to delete the information and reduce the size of the file.
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.

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.
i encoutered lately on such statement:
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;

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.
would want to check which tables located in which datafiles.
Tried with this command:
select B.FILE_NAME from dba_segments a, dba_data_files b
where a.header_file=b.file_ID and segment_name='TABLE_NAME'
Seems like it only shows 1 datafile. Some tables are large and i suppose it's resided in more than 1 datafile.
what's the difference between having BIG datafile (32GB) vs many small datafiles (4GB) replacing a Big one.
View 3 Replies View RelatedWe 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 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 want to delete one datafile from tablespace witch contain 2 datafiles
i did
ALTER DATABASE DATAFILE 'ton_fichier' OFFLINE DROP;
and delete the file physiquly but i have already my datafile witch i have delete in my 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.

how to recover those tablespace's datafile?What happened to earlier tablesapce backup?
I need tablespace name,tablespace total size and used size of every tablespace for my 106 databases. bcz I am planning to prepare tablespace growth report for my 106 dbs. If I have the 2 months data from now in xl sheet, then I can predict the growth rate of every tablespace accurate almost.
it is not a easy task to fill the space detail manually in xl sheet everyday.Hence I need some mechanism to do this activity automatically.
I know we can collect this detail in a csv file every day while running the script. but is there any mechanism to store these detail in a particular xl sheet one by one column automatically?
I am using oracle 8.1.5 database and my temp01.dbf file size is increased upto 19.8 GB now i want reduce its size .
View 13 Replies View RelatedI 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.
Create a table with 100 records.Then write a BULK COLLECT Cursor that can reduce the number of context switches by using a bulk fetch to query records in sets or all at once.

I need to create a tablespace for administration of database but i don't know what datafile settings are best suited for admin usage.
I have attached the schema that was given to me for this assignment.
