Shrinking undo Tablespace
Shrinking undo Tablespace
What is the preferred why to shrink the UNDO Tablespace ?
1. To create new UNDO TBS , order the DB to work whit it , and drop the oldest.
2. To shrink (resize) the exists one .

2. To shrink (resize) the exists one .The first one would be a better approach as there may be users who are still using the old tablespace. So for all of them, you would see a Pending Offline status. Once all teh segments release the old information stored in them, you can remove the tablespace. By trying to shrink the tablespace, you actually would be increasing the chances to get the 1555 error and also, this won't be happening as already there is a used space in teh datafile.

Hello,
We had a UNDO Tablespace of 22Gb but it is using just 2GB. How to shrink undo tablespace. we are using clustered 3 node production database 10.2.0.4
Is there is way that we can shrink UNDO Tablespace or do i need to create a UNDO tablespace and assign the undo tablespace to DB and drop the old UNDO?
How to ensure that transactions are done and free to drop the old UNDO?
Is it something we need to restart all the three nodes as each node has its own UNDO Tablespace.
Need Help on this issue.
would appreciate your quick response.
Thanksif i am in your place i will do the following:
<pre class="jive-pre">1-Query DBA_DATA_FILES to determine the name of the datafiles of the UNDO</pre>
2. Create a new UNDO tablespace.
<pre class="jive-pre">CREATE UNDO TABLESPACE undo_ts2 DATAFILE '/directory/undo_ts2_01.dbf' SIZE xxxM;</pre>
3. Modify the database parameter to use the new UNDO tablespace.
<pre class="jive-pre"> ALTER SYSTEM SET undo_tablespace=undo_ts2 SCOPE=BOTH; </pre>
4-The Drawback:
<pre class="jive-pre">New transactions will begin using the new undo tablespace. After some time passes (at least the number of seconds specified by the UNDO_RETENTION initialization parameter), you can drop the old UNDO tablespace. The downside to this approach is that for a short time period, your database will have two UNDO tablespaces</pre>

Unable to shrink undo tablespace... Help!
Hi,
I have problems to shrink the system undo tablespace, which has grown up to 14 GB.
I use 9.2. Table space owner is 'SYSTEM', undo_management = AUTO.
I tried to shrink the greatest rollback segments by the commands
ALTER SESSION SET UNDO_SUPPRESS_ERRORS = TRUE;
ALTER ROLLBACK SEGMENT "_SYSSMU6$" SHRINK TO 20 M;
Oracle confirmed these commands, but nothing happened.
What am I doing wrong?
Hermann MuellerYou have seen the discussion about the undo segments, on the temporary tablespaces, you should be aware that the sort segment of a given temporary tablespace is created at the time the first sort operation takes place. The sort segment continues to grow by means of extent allocation until the segment size has reached the total storage demands of all of the active sorts running on the instance. Oracle will keep on allocating temporary space on demand unless the physical limit states otherwise.
Temporary segments are produced each time a sort operation (explicit -order by- or implicit -aggregation, reindexing-) requires to sort a set that cannot fit into memory. So if you detect excesive sort usage you should aim your monitors towards the sort operations (reports, reindexing, max, min, aggregations, order by ...). If your system has a DDS behaviour, this kind of operations are frequent as a massive sorting has to be peformed against millions of rows.
A Temporary tablespace will almost always appear to be near 100% full, that's because once oracle has allocated temporary space it doesn't release it back to the free space, it keeps it allocated even when the sort operation has finished. Criteria behind this fact is similar to the one oracle used to have when the rollback segments were in use, Oracle only allocated space and the dba should perform manual actions to release space, and the criteria is performance. Once it has allocated space this big, there are possibilities that the same circumstances that raised the temporary usage high water mark to this level are repeated, so if oracle keeps the mamimum allocated space, it won't have to allocate the same storage once more.
Main concern with temporary tablespace growth is not free space itself, but the reasons why this amount of space was allocated, so I suggest you to track the sql statements with sort operations. If you are certain the circumstances that motivated this amount of temporary resources to be allocated won't be repeated again, then you could think of resizing down your temporary tablespace. I suggest you to create a new temporary tablespace with the desired size, and alter the default tempoary tablespace to point to this newly crated temporary tablespace, and finally get rid of the original temporary TS.

Segment shrinking and UNDO tablespace
When i issued
alter table <table_name> shrink space cascade;
I got the error 'Unable to extend UNDO ...by 8' . Does Segment shrinking consume space from UNDO tablespace?
Message was edited by:
for_good_reasonAs Jonathan said, shrinking segment generates redo and undo data.
But, this phoenomenon of undo shortage is not normal case.
Shrinking segment might invole continous DML(deleting and re-inserting),
but it's transaction seems to be committed internally at regular intervals.
For this reason, shrinking operation should not hold undo area that long.
But have no knowledge on exact behavior of shrink operation.
Someone else will shed a light.
How big your table and indexes?
Some cases are reorted that shrinkage on big segment generates really large amount of undo data.
This might be related with your problem. But not sure.

Cannot shrink the undo tablespace
Hello!
I have run a very long procedure, which generated 15GB undo information. Now I can see in the enterprise manager, that the undo tablespace is empty again. I tried to resize the datafile, but I receive "*ORA-03297*: file contains used data beyond requested RESIZE value". How can I shrink the tablespace without dropping and recreating it?
I tried also
purge recyclebin;
I still get ORA-03297 if I try to resize the datafile.
I wanted to try something like
ALTER TABLE xxxxx UNALLOCATE UNUSED;
or
ALTER TABLE xxxxx SHRINK SPACE;
but are there any tables that save the undo information?
Regards.Hi
well, my transaction is ready! The undo tablespace has not more that 10M of information, the other 15G are free!
Thanks for the answers, it seems that i still have recreate it ...
Well, another quertion:
Is it possible, that I just have to wait longer before I resize the undo data file? I have just succeeded in resizing the data file to 7 GB. I really wish I could shrink it to 100M or so, but still - from 15G to 7G is a lot better! 2 hours ago this action was not possible. Is it some automatic management, that needs to time-out before I can shrink the undo tablespace?

UNDO tablespace resize/shrink.
Hi All ,
is it possible to shrink/resize undo tablespace.Hi Shobhit!
I is correct that you're unable to set this parameter with ALTER SYSTEM. Please never use this parameter unless you are told to do so from oracle support. Maybe you're playing with your support if you set it by your self. To tune the size of your undo tablespace set the parameter undo_retention. Whit this parameter you tell your DB in seconds how long undo records should be kept within your undo tablespace. Automatic undotuning will be automatically activated if this parameter has a value greater than 0. To determine the correct size you need for your undotablespace use the following example:
Size of UNDO needed = UNDO_RETENTION x [UNDO block Generation per sec x DB_BLOCK_SIZE] + Overhead(30xDB_BLOCK_SIZE)
Out of these we know UNDO_RETENTION and DB_BLOCK_SIZE
All we need is to find out “UNDO Blocks per second”
Which can be easily fetched from v$undostat
SQL> SELECT (SUM(undoblks))/ SUM ((end_time - begin_time) * 24*60*60) "UPS"
2 FROM v$undostat;
UPS
8.11985583
V$undostat
stores data for every 10 mins and begin/end times are start/end time of
those intervals. We multiplied it with 24*60*60 because the difference
between two dates will be in days and to get to seconds, we need it to
multiply with 24hrs*60mins*60secs
So now we have all the values needed.
Undo size needed = [8.12 x 2000 x 8192] + [30 x 8192] = 133283840 bytes = 127.11 MB
Hope this helps!
yours sincerely -
Hi guys.
Our database has 50GB of undo tablespace. I decided to create a second undo tablespace and switch to the new one. Since doing that yesterday, the size of the old undo is 49GB (was thinking that the values will drop to zero) and the new tablespace keeps increasing in size! Its size now is about 20GB. I do have the following question.
a) If I restart the database, it the value of the old undo going to fall to zero?
b) undo_retention=86400. Setting this value to a lesser value say 800seconds, it is going to act the performance of the database? Is it going to release the space on the old undo?
Thanks and any help is appreciated.
DavidThe undo tablespace will not automatically shrink size, since you have a new undo tablespace in place. You can drop the old one if you don't plan to use it.
Set lower undo_retention will certainly help to contain the undo space usage. However you should query v$undostat and v$rollstat to estimate the amount of undo space required for the current workload then size the undo tablespace accordingly. Turn off the auto extend on undo tablespace. -
Undo tablespace growing without reusing space
Hi,
I'm running an Oracle9i database on Solaris. I am using the automatic undo management and I have one undo tablespace. The UNDO_RETENTION value is 900. I have created the undo tablespace this way (clause in create database statement):
UNDO TABLESPACE "UNDOTBS1" DATAFILE '/u04/oracle/oradata/my_dbname/undotbs01.dbf' SIZE 200M REUSE AUTOEXTEND ON NEXT 5120K MAXSIZE UNLIMITED
The undo tablespace datafile is now close to 3G. I have other servers running the same setup, and their undo datafile size is still 200M. There is currently no active transaction in the database. Any idea why this is happening? Is there any tables I can check for clues?
Many thanks,
GloriaShould Oracle automatically shrink the undo tablespace (datafile) when it is not needed anymore? Say at one point the database really needs 3G of undo tablespace, but afterwards only 10M is needed, would the datafile be 'shrunk' back?
Also, how can I check if the database really needed the 3G of undo tablespace at one point? (I guess it's checking the level of activities in the database, but how do I do that for past data?)
I'm trying to decide whether the undo tablespace really grew due to a need at some point or is it a case of Bug 2660394 (documented in metalink note271119.1). The bug basically says that "An auto extensible undo tablespace MAY grow before reusing expired extents leading to more space use than actually needed". -

Regarding Maxsize of Undo Tablespace
Dear expetrs
While executing a procedure i got error.
Error In Insertion..ORA-30036: unable to extend segment by 16384 in undo tablesp
ace 'UNDOTBS1'
then i increase the size of the Undo Tablespace
then again i got error.
ORA-01144: File size (7680000 blocks) exceeds maximum of 4194303 blocks
plz give me answer as soon as possible.
thnaks.1) resize your datafile to 4194303 * db_block_size
alter database datafile < path/filename > resize <4194303 * db_block_size> ;
you find db_block_size by:
sqlplus /nolog
SQL> connect / as sysdba
SQL> show parameter db_block_size
or by simply have a look in the pfile (init<SID>.ora) in $ORACLE_HOME/dbs
2) add another file to the undo tablespace:
SQL>alter tablespace undotbs1 add datafile <path/filename> size <n> M;
a tablespace may have up to 1022 datafiles.
hope this helps

Undo tablespace recovery from RMAN backup
Hi,
Lets's assume we have RMAN backup and archivelog backups, and now
my undo tablespace's disk crashed ,how can i recover?
Can i recover while database is up?
Thanks,
Kumar.to recover UNDO tablespace from RMAN backup you must shutdown the database and start it in the MOUNT state to recover the missing files as follows
rman target /
RUN
STARTUP MOUNT;
ALLOCATE CHANNEL ch3 TYPE Disk;
RESTORE datafile 'c:\u01\prod3\undo01.dbf';
RECOVER datafile 'c:\u01\prod3\undo01.dbf';
ALTER DATABASE OPEN;
RELEASE CHANNEL ch3;
hope this will help you -
Hi!
I have been having problems for the past couple days with restarting my database. For some reason when I shutdown, once I start it up again the undo tablespaces is offline and needs to be recovered. When the application tries to connect to the database it gives a "ora-01552 : cannot use system rollback segment for non-system tablespace." I do a recover on that tablespace and bring it back up, and it works fine... until the next restart.. Would anyone have an idea on what's the problem, and what I can do to fix it once and for all?
Thanks
Yazil Santoyodid you try metalink, there are lot of options / suggestions for your particular error.
Is your database in Auto undo mode or manual undo?
Thanks
