UNDO Tablespace size
Hi,
We have a production database with size 120GB (DB Version 11.1.0.6), And our UNDO Tablespace size is 30GB.
For the past 4 days the UNDO tablespace utilization is more than 85%.
We have disabled the AUTOEXTEND for the UNDO Tablespace.
So the UNDO RETENTION is dynamically calculated by Oracle itself and the value now is
TUNED_UNDORETENTION
339183
Please suggest how to fix this issue.
Thanks !
Hi,
The UNDO Tablespace size is still increasing. We dont have flashnack enabled for our database.
The database is 11.1.0.6 Standard Edition.

Please let me know how can i reduce the space consumed by UNDO Tablespace.

How to estimate undo tablespace size in 11g?
I found someone document said, use this sql to estimate undo tablespace:
select (UR*(UPS*DBS))+(DBS*24) as "bytes" from (select value as UR from v$parameter where name='undo_retention'),(select (sum(undoblks)/sum(((end_time-begin_time)*86400))) as UPS from v$undostat),(select value as DBS from v$parameter where name='db_block_size');
but in my 11g database, the "select value as UR from v$parameter where name='undo_retention'" is 0. so above sql is always get 196608(8192*24)
How to estimate undo tablespace size in 11g?
Thanks very much!for undo segments size you should turn it to be autoextend on as well undo management set to be AUTO
i.e
undo_managment='AUTO'
for retention see that link
Ora-01555, snapshot too old: rollback segment number 2 with name "_SYSSMU1
BTW as hemant stated leave it to be auto which is good approach but make sure enough space on disk has been
dedicated for undo segments are allowed to grow to the size they need to be based on the requested undo_retention.

Cacluation of undo tablespace size and retenion
How to calaculate the expected size of the undo tablespace and undo retention parameter from the exisitng data.
The easiest way to calculate undo requirementes is using the undo advisor, it is available in 10g and 9i. This is a graphical tool that lets you know the amount of required undo space according to your generated undo data.

FLASHBACK OFF FOR UNDO TABLESPACE????
Hi all
As my Undo tablespace growing evryday 2 GB & NOW it reached 19,
Database size is 6GB only
using Oracle 10g Release 2 without patch Set (release 1002000100) on Hp-Unix OS
Can i use the Undo tablespace with FLASHBACK OFF option?
what are the Consequences for Turning off the FLASHBACK,
Can we use this type of Undo tablespace with Flashback OFF???

THANKS ALOTOracle Flashback Database: feature is similar to conventional point-in-time recovery in its results, allowing you to return a database to its state at a time in the recent past. It is, however, much faster than point-in-time recovery, because it does not require restoration of datafiles from a backup and it requires application of fewer changes from the archived redo logs.
UNDO Tablespace: Oracle db save the old value when a process change data in undo tablespace.
I think that you can change de default UNDO tablespace as NO AUTOEXTEND, and
Configure
SET UNDO_MANAGEMENT=AUTO
SET UNDO_RETENTION= ( second need for logger transaction )
UNDO_RETENTION specifies (in seconds) the low threshold value of undo retention. For AUTOEXTEND undo tablespaces, the system retains undo for at least the time specified in this parameter, and automatically tunes the undo retention period to satisfy the undo requirements of the queries.
For fixed- size undo tablespaces, the system automatically tunes for the maximum possible undo retention period, based on undo tablespace size and usage history, and ignores UNDO_RETENTION unless retention guarantee is enabled. -
Relation between undo_retention and undo tablepsace size
Hello,i am on 10.2.0.3.
Can someone please clear this things a little bit.
Let's say that i have one SQL that is doing inserts or updates and this have execution time of 30 minutes,
and my undo_retention parameter is set to 20mins, undo_management=auto, and undo tablespace of 30GB of which is curently taken only 1GB,
will this insert fail with ora-1555 snapshot too old or not ?
Is undo_retention the only thing that determines how long query can be run or i can focus on undo tablespace size also if there is enough space in it ?No, the DML activity load on the system during any given period of time is the most important factor in how your undo is handled. How you define your undo tablespace in your choice of building it using extendable data files or with a fixed size (my recommendation) also comes into play.
If you use a fixed size undo tablespace Oracle will attempt to use it all before overlaying data.
The DBA Administration manual has a decent discussion of undo tablespace managment and sizing considerations in the chapter on managing undo.

ORA-30036: unable to extend segment by 8 in undo tablespace 'UNDO'
Hello,
I have an OWB Mapping (which translates into a MERGE query) that often fails with the above error. I wanted to have more information on UNDO. What uses most UNDO?
Thanks.Dear mugunthan,
One little, tiny correction that i want to make. I can get what you wanted to say when you said "increase the tablespace". Normally we are not increasing the size of the tablespace, we are increasing the size of the "datafiles" in that tablespace. That is tricky and how words can change everything i know but just for the information :)
I think the OP's undo tablespace size is 100% full and the auto extensible ability is disabled. He needs to either increase the size of the datafile in the undo tablespace slightly more or enable the auto extensible of one more datafiles (if exists) to a particular new and more bigger size.
Regards.

Undo retention and tablespace size
Situation:
Oracle 9.2.0.1 configured with undo_retention=10800 but with a 2GB size limit for the
undo tablespace with no autoextend.
As far as i know, with 10800 the undo tablespace could grown to around 10GB
but i'm not sure tho. I REALLY need to know if this is clearly a wrong setup (imho it
is) or could be an acceptable situation in some scenarios.
Thanks heap in advance.Oracle 9.2.0.1 configured with undo_retention=108003 Hours? This is realy huge undo retention time.
with a 2GB size limit for the undo tablespace with no autoextend.You probably mean datafile not tablespace.
You don't need resize existing datafile you could just add another datafile to undo tablespace. -
UNDO tablespace file size is huge
Have noticed that UNDO tablespace is eating the disk space of our server. Now, the size is 40GB. Can I recreate a new one with smaller size and drop the existing one? If yes, how?

UNDO tablespace reaching maximum size - WHO is using it?
My UNDO tablespace has been pretty static for a while but this morning it was at 93% and within 20 minutes I saw it at 98%. I added a datafile to buy some time, but is there any way I can identify specific sessions which may be filling it rapidly ?

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

Error is because in target database undo tablespace is UNDOTBS_NEW and in auxiliary database undo tablespace name in init file is UNDOTBS. I followed the meatlink doc 433992.1 which suggest following steps to recover from above error:
1) edit the parameter UNDO_MANAGEMENT to "MANUAL"
2) start database again
3) drop the UNDO tablespace
4) recreate UNDO tablespace which matches to name in init file.
5) shutdown & start DB again.
Now, i edited init file and tried to start DB and got following error:

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. -
Is there so call "dedicated" UNDO tablespace in Oracle 9i and higher?
Since one of our applicaions needs to process large amounts of data, we have been using a dedicated rollback segment in order to avoid the "snapshot too old" problem.
Recently our DB upgraded to Oracle 9i and DBA asked us to use "undo" tablespace.
Based the Oracle 9i Doc., it only allows to select ONE undo tablespace at a time.
If so, DBA has to make the only UNDO as large as our Cash large transactions
need(adjust the UNDO_RENTION), which inevitably waste lots of space.
Does Oracle 9i allow to have one dedicated UNDO tablespace for large transactions while another one for regular transactions just like we use the old rollback segments.
Thanks in advanceWhy have multiple UNDO tablespaces? You can only use one at a time, and when the other one is not being used, it still consumes storage space.
Spend a little time determining how much undo you need and size undo tablespace and undo retention around those values and you should be able to resolve the problems you are experiencing now.

Hello:
I've created a new undo tablespace undotbs2. I've set it to the default undo tablespace. When I've tried to drop the old one, I get the following error:
SQL> conn / as sysdba
Connected.
SQL> DROP TABLESPACE undotbs1 INCLUDING CONTENTS AND DATAFILES;
DROP TABLESPACE undotbs1 INCLUDING CONTENTS AND DATAFILES
ERROR at line 1: ORA-01548: active rollback segment '_SYSSMU7$' found, terminate dropping tablespace
This is a production database. The service is down because the partition with the Oracle tablespaces: system, undo, temp, etc is full.
After shutting down the database the problem persist: I cannot drop the old undo tablespace because of the same error.
I've followed the note 1321093.1. Here the query results:
Select segment_name, status, tablespace_name, rs.segment_id
from dba_rollback_segs rs
where status not in ('ONLINE','OFFLINE');
_SYSSMU7$ PARTLY AVAILABLE UNDOTBS1 7
SELECT KTUXEUSN, KTUXESLT, KTUXESQN, /* Transaction ID */ KTUXESTA Status, KTUXECFL Flags

SELECT LOCAL_TRAN_ID,GLOBAL_TRAN_ID,STATE,MIXED,COMMIT# FROM DBA_2PC_PENDING;
No rows
SELECT LOCAL_TRAN_ID,IN_OUT,DATABASE,INTERFACE FROM dba_2pc_neighbors;
No rows
As you can see, there is no pending transactions. No application is connected to the database (service is down), however the database is appling rollbacks since 2 days.
A lot of archivelogs are being created at rolling back (30 GB archivelogs per hour). Here a tail of the alertlog file:
