Database rman backup failed with file does not exist. Go to solution. April 24, - am UTC. Thanks Tom for reference. It was useful. I conclude that, shall I create a new file belonging to that tablespace and rename the missing one to new one. P, April 26, - pm UTC.
April 26, - pm UTC. In order to drop it -- you need to get rid of that entire tablespace. Say a tablespace is a glass. Datafiles are water. You add a cup of water to the glass. Later you add another cup of water. Now -- why can't you remove that last cup of water? They are all mixed together, all the same. You can shrink the amount of water like you can resize a file within limits but you cannot get rid of the "first cup" of water or the "second cup".
The way you cleared the concept of datafiles and control files was absolutely excellent and helpful. Dear Tom! I am running my database in NonArchivelog mode. One of datafiles of tablespace RBS got corrupted as shown below. All Rights Reserved. Oracle8i Enterprise Edition Release 8. Database opened. DBF' offline; Statement processed.
Please advise what should o do in order to re-create the tablespace RBS and its datafiles. I have no physical backup for this database. However, i've logical backup for this database. I am using 8. Datafile Size 8. Tom, Is there a limit on the size of a single Datafile in a tablespace on Windows Server?
I have read somewhere that it is 2GB but i'm not sure about it. If so, what the reason for the limit? Thanks, Sriram. October 14, - pm UTC. Resize the datafile S. Darshan, October 15, - am UTC.
Dear Mr. Tom, Thanks for your example regarding Tablespaces and Datafiles, Particularly "Say a tablespace is a glass. I have a table1, table2, table3 in Archive Tablespace. Now free space for Archive tablespace is 4GB. I want to resize the tablespace size to 2GB or 2. How can I resize? Can you help me? With best regards S.
October 15, - am UTC. Suppose the three files look like this: from 0m to 2gig in size -- f is "free" and U is used by table1 0m m m m m ffffUUUffffUffffffffffffUffffffffffffffffffffffff file 1 fffffffffffffffffffffffffffffffffUUffffffffffffff file 2 ffffffffffffffffffffffffffffffffffffffffffffffffU file 3 Now, file 1 can be shrunk to 1gig in size -- there is nothing used beyond 1gig in that file. Even though that file only has 2 used bits -- they are way in the middle file 3, with the least data, will be the biggest file.
It cannot be shrunk at all in this example. Now, if you are using LMTS -- you can try "alter table table1 MOVE" -- that'll tend to reorg the table and put all of the bits at the "front" of a file. Then you can shrink perhaps remember to rebuild indexes after moving a table like that! If you search for maxshrink on this site you find a script that will tell you how small ever datafile in your database can currently be shrunk to.
The answere to the question regd. Data file where too good. A reader, October 15, - pm UTC. Linda, February 06, - pm UTC. Saved my tailend! This does not seem to be documented anywhere else. Difference between offline and offline drop. Alvin, February 29, - pm UTC.
If the database is open, you must perform media recovery on the datafile before bringing it back online, because a checkpoint is not performed on the datafile before it is taken offline. When t1 becomes corrupted and i need to recover it i would : 1. As per cut and pasted document above : 1. Does that mean that 'offline drop' is used on databases that are in noarchivelog mode??
And we use 'offline' only when we are in archivelog mode? March 01, - am UTC. It lets you remove the thing that is broken in noarchivelog mode or in archivelog mode when you have no backups you can use.
In OMF corresponding db files are not deleting Then i created a table on it. When i issue "drop tablespace test including contents and datafiles" ,its not deleting the the corresponding db files.
What's the reason for not deleting the db files. Then i connected to scott and created a table to use newly created tablespace. So, now emp1 uses test tablespace.. Why it is so? Oracle 9. Hi tom, I've got a little question about the links you post here to Oracle-documentation, e. Has this something to do with a re-organisation of the Oracle-site? Oh yeah, ofcourse I'm registered with Oracle, so that's not the problem.
Not really looking for a "solution" for this thingie, just wanted to let you know.. Greetings, Victor Oosterbaan. Hi tom, I tried in W2k professional, windows server and Sun SPARC 9 in all machine db is oracle , but in windows machine its not deleting the corresponding db files and in sun its doing. Other one i've to remove it manually. Any reason for this? I did the same thing in SUN machine , its doing what it has supposed to do.
March 02, - am UTC. I love that last sentence : but I won't touch it All rights reserved. Connected to: Oracle9i Enterprise Edition Release 9. April 02, - am UTC. Strange thing? I was testing on my home PC.
Here is what I did. Pls tell me why it happened? On Oracle 9. I tried sorting and creating temporary table. It worked fine without any problem. I could able to create it. Then I tried with Non-Temporary tablespace I mean permanent tablespace. I found the same behaviour. I hope you understood my question. May 26, - am UTC. The temporary tablespace you assigned to the use was dropped. That does not change the fact that the user was assigned to it, they would just recieve an error upon "needing it".
This is the way it has always worked. It is data we will use at runtime to find out what tablespace should be used. If you dropped it, user gets runtime error. If it exists, fine, we'll use it. May 27, - am UTC. You do not believe your own eyes????
You observe a behaviour and do not believe it is happening? It gets a name and if that name exists -- it uses it, else it fails the statement. Just like when Oracle gets a create without a tablespace, it goes to 'dba users' and asks what is the default tablespace for this user.
I cannot tell you want you thing you "want" to hear. A Query on Datafiles Praveen. B, June 04, - pm UTC. Hi Tom, I went through the discussion right from scrach. I was extremely useful. My problem is vey much related to this. I tried making the datafile offline. To can u give me a solution. June 04, - pm UTC. By doing a restore and recovery or just making the file available once again. A reader, June 04, - pm UTC. We restored the control file from the latest backup. Then we restored the particular data files that reported as corrupt.
The last step was to recover the database. The recover database checked for the archive logs in the disk and if it was not available, it automatically restored the archive logs that were needed. We had developed our own recovery scripts and made sure we had tested them with the different scenarios. So all we did was run those scripts, sit back and monitor the log files. Thanks, Rahul. A small clearance Praveen. B, June 05, - am UTC. Hi Tom, Oops a bit of confusion!!. I will come back to my question.
Most likely this is in a database that was cloned from an other database and the tempfiles are not added. Oracle needs a functional temporary tablespace to be able to process joins and sorts.
