Undo tablespace to recover without backup

Hello

I put one of my data file that contains in the undo tablespace. Now, my database is in the editing stage, when I tried to open the database, it gives me the following error:

SQL > alter database open;
change the database open
*
ERROR on line 1:
ORA-00376: 17 file cannot be read right now
ORA-01110: data file 17: ' / misc/live_tbs/undotbstest.dbf'

My database is in noarchive mode more I do not have a backup.

Thank you for your cooperation.

Kind regards

Adnan Hamdus Salam.

NOarachivelog mode and having no backup are, in fact, a perfect recipe for disaster. What happens when you transfer the file online in the editing phase?

You have rman or backup to hot/cold? If so try like:
* 1.*
```
sqlplus "/as sysdba"
shutdown immediate;
startup mount;
/*restore undo datafile then*/
recover datafile 37;
alter database open;
```
* 2 If you have backup rman, then try
```
rman terget /
blockrecover datafile 37 block 25;
```
* 3.* If you don't have a backup, you can start your database without this undo tablespace.

1. backup current database;

2. change pfile (parameter file) change undo_tablespace and undo_management as:
```
undo_management=manual
undo_tablespace=UNDOTBS2
```
If you do not use pfile create pfile from spfile as:
```
sqlplus "/as sysdba"
create pfile='pfilelocation' from spfile='spfilelocation';
```
3. then start database as:

Create the State of Mount, possible undo tablespace?

Oracle 10g (10.2.0.1.0) on RedHat 4 (the two 64-bit)

My test db & rsquo; s undo tablespace is corrupted (no backups RMAN or user).
DB fails to open, fails in

"Doing block recovery for file 2 block 209910"

Is it possible to create undo tablespace while State of Mount?

I'm pretty confident it & rsquo; s is not possible, was also searched on the net and can't find any solution, I thought I'd ask.

UNDO Tablespace backup-RMAN
Hi/team champions,
I'm confused in full DB Backup RMAN why CANCEL tablespce is included even we include also archive logs.
in a Word?
Why UNDO tablespace backup is necessary while taking backup RMAN?

Kind regards
Shitesh Shukla
If I do not want to include the UNDO tablespce in my backup

What happens if I took only backup files except CANCELLATION n TEMP

NOT an option. You must include UNDO. 11g has optimization in order to safeguard an Undo tablespace.
10 gr 2 what you pourriez do is

1. create a new Undo Tablespace
2. position yourself in the new Undo Tablespace
3. check that the old Tablespace Undo is no longer in service - confirm that there is no transaction active in the inside undo segments
4. remove the old Undo tablespace
5. start your RMAN backup

You run the risk of
a. wait long to step 3
b. ORA - 1555 s for users once you drop the Undo tablespace to step 4.

FLASH BACK TO THE WIDE FOR UNDO TABLESPACE?

What are the consequences to extinguish the FLAME,

The (increasing) size of the Undo Tablespace has no impact on performance.

One of the possibilities:
He'll do backups take longer... so if you perform backups online, then the lengthy backup may be creeping in the moment of the request of the user.

About what I know, you should be able to RESTORE the data, but no RECOVERY without portfolio being opened.

Check the value of the variable environment - ORACLE_UNQNAME

It has everything first a correct value and try to open the wallet.

Undo tablespace increasing
Hello

my version of the database is 11.2.0.1.0

My undo tablespace was approximately 36 GB and 4 GB was about free.

But now the size decreases and it is falling fast. What I would do. I increased it by another 2 GB. How to monitor it so that I can capture it without resizing again.
Please guide me.

Thanks in advance.

Undo tablespace continues to grow
Hello
My undotbs grows to 14g (even if I have my undotbs actul size 9g) I try to resize the data files, but
This may not work.

So, I guess for this task

>
-Create a new as undo tablespace:
SQL > create undo tablespace UNDOTBS2 datafile "< full file path >" size < small >;

-Change the parameter UNDO_TABLESPACE
SQL > alter system set UNDO_TABLESPACE = UNDOTBS2;

-Remove UNDOTBS1
SQL > drop tablespace UNDOTBS1 including content and data files; >

but my question is, is he worthy of delete the undotbs1 whose having a lot of data and if I deleted
These data (undotablespace), I won't be able to completely recover?

db_version:10.2.0 (Linux)
There is procedure to drop undo tablespace. If you already increase first then I suggest you to study why his is growing? Check with developers, to monitor the database

Free tablespace on undo tablespace
I have a 8Gig tablespace on database 94Gig which is used for the statement (this is DSS database). Retention of cancellation is set too high (it is 1080 about 3 h). I don't know what is the reason, but it space table undo is full all the time, because of this it is ETL jobs that suppose to run each night fail.

I think bounce (restart database) to free up to undo tablespace.

Do you propose to increase the undo tablespace tablespace or database rebound must release undo tablespace? Please suggest.
In an SSD long requests are expected. You need your UNDO retention to be longer than your long query, so the 'too long' claim is rather subjective.

Unless you have the cancellation retention set, Oracle will reuse space annulment, even crush UNDO for younger than retention committed transactions to meet the current requirements of the query.

Even if you restart the database (which is a horrible idea, from the pit of Redmond) conditions that are initially complete you the UNDO and get errors are likely to come immediately.

Refresh jobs fail with ORA-01555 or ORA-30036? For these solutions are very different.

I agree with the first line... allocate more space to CANCEL is probably the solution here, but we cannot say that for sure without knowing the error (and Oracle version would be helpful, too).

excluding tablespace in the hot backup
Hi master,

I use oracle 10g on linux. We use the hot backup to date strategy to back up the database.

but I think that I support too much data. I now have tablespeces in my database

System
users
Temp
Cancel
index
perfstat
blob1
tool
etc. and default tablespace installed by oracle at installation time.

I can I exclude some of the hot backup table spaces so that it consumes less time to back up the database?

can I exclude spaces of temp, perstat and tool table?

It will cause no impact on the database and?

Thanks and greetings
VD
DON'T think to drop your UNDO tablespace. You use it to save "in front of your block images.
