Rollback segment error

Hello experts,
My problem is as follows:
I need to perform a large transaction on one of my tables in my
database. I have to delete a large number of records using a
command as follows:
Delete from mytable where ordernumber like '2000%';
Each time i launch this command i have the following error:
ERROR at line 1:
ORA-01562: failed to extend rollback segment (id = 3)
ORA-01628: max # extents (30) reached for rollback segment R03
I know that i have a problem with my rollback segment. I have
thus created a large rollback segment so that my transaction can
use it.
I don't know how to tell my transaction use the large rollback
segment that i created.
(i know there is a command called set transation user rollback
segment large_rs1, i have tried it on sqlplus. it gives me
error: ORA-01453: SET TRANSACTION must be first statement of
transaction)
Please help
thanks in advance for a reply
Kind regards
Yogeeraj

First, you have to create a bigger rollback segment (i.e. RBBIG).
Then, before each query, you must type:
set transaction use rollback segment rbbig;
This will force the use of the specified rollback segment.
Hope this helps.

Rollback segment error ORA-1628

Hellow
Currently we are working on Oracle 8i database.The database contain spatial data around 10GB.We have a tablespace RBS containing 4 rollback segments. The issue is whenever we try to insert spatial data we get this error message (in the alert file)
ORA-1628: max # extents 121 reached for rollback segment R01
Failure to extend rollback segment 2 because of 1628 condition
FULL status of rollback segment 2 cleared.
I extended the size of RBS tablespace by adding another datafile, but still it doesn't help.
Also i found that RBS tablespace is marked as PERMANENT...it means the rollback data does not get flushed out periodically?Also Should this tablespace be temporary? How can i counter this problem?
Regards
Sam

Hi,
01628, 00000, "max # extents (%s) reached for rollback segment %s"
// *Cause: An attempt was made to extend a rollback segment that was
// already at the MAXEXTENTS value.
// *Action: If the value of the MAXEXTENTS storage parameter is less than
// the maximum allowed by the system, raise this value. => Alter your RBS and allow more than 121 extents to be created in this RBS.
Also i found that RBS tablespace is marked as PERMANENT.Yes, it's normal.
..it means the rollback data does not get flushed out periodically?No
Also Should this tablespace be temporary? No, this can't be
How can i counter this problem?Free advise: RTFM about Rollback Segments! Start here (8i doc) or read the Concepts book.

Export backup failing with ORA-1555snapshot too old: rollback segment ERROR

DB version =8.1.7.4
OS=Solaris =5.10.
I know this is outdated. But still we are supporting this version of database.
We are facing ORA-1555 error daily when we are running the export backup of database. Consistent parameter is set to N .
I needed to know why export uses rollback segments during export operation. even though CONSISTENT parameter is N.
Thanks,
Edited by: ahshivap on Dec 12, 2012 5:19 AM

Hi,
Consistent=y just mean the tables are consistent with each other. Oracle still has to guarantee that each individual table is at least consistent with itself. That's your issue.

Hi,
Its ora-1555? IS your undo_retention sufficient?
Since you are developer the only option you have is to tune the query?
Am curious to know like I create materialized view so that I do not have to run complex query on the master database / or to prevent the access to master database more than once to get the same data?
Like to know which is your case because your query seem to be too complex to be the case for former. Do you think this materialized view would be used frequently in your application?

Error while creating the rollback segment (Oracle 8i & OS Win NT)

hi
I am using Oracle 8i and when i am creating the new rollback segment for my database i have got following error message
ORA-01593 Rollback segment optimal size (30 blks) is smaller than the computed initial size (2560 blks)
CREATE ROLLBACK SEGMENT "RBS11" TABLESPACE "RBS1"
STORAGE ( INITIAL 120K NEXT
120K OPTIMAL
240K MINEXTENTS 2
MAXEXTENTS 100)
Note:- db_block size is 8k
Tablespace RBS1 is the Locally managed Tablespace having datafile of 50m and uniform size of 10m
But Given statement processed while i am using Tablespace RBS (winch is data dictionary managed)
Plz, suggest me to cause of that error and solution

You said 120K optimal and initial is 120K with minextents of 2. The optimal size then will be smaller than the initial allocation for the rbs.
ORA-01593: rollback segment optimal size (string blks) is smaller than the computed initial size (string blks)
Cause: Specified OPTIMAL size is smaller than the cumulative size of the initial extents during create rollback segment.
Action: Specify a larger OPTIMAL size.

Error rollback segment while exporting a table

I am getting error while exporting a table, can someone advise me how i can handle this issue.
EXP-00056: ORACLE error 1555 encountered
ORA-01555: snapshot too old: rollback segment number with name "" too small
ORA-22924: snapshot too old
Thanks

Hi, I have the same problem...
I have a table with a blob type (14740 records)
I have increase the PCTVERSION to 100 (= maximum)

undo tablespace = 2 Gb
exporting with parameter CONSISTENT=n
Still I got the message
EXP-00056: ORACLE error 1555 encountered
ORA-01555: snapshot too old: rollback segment number with name "" too small
ORA-22924: snapshot too old
When exporting the table
What do I have to do more ?????

Urgent: Error ORA-01555 "snapshot too old rollback segment too small"

I get this error when I do a "SELECT" on a few very large tables for a report. Isn't there a way out? Our DBA says our rollback segment size cannot be increased anymore. All I care of is the SELECT statement to finish executing. It is okay for me to have some inconsistency in the data (dirty reads). What is the easiest way to solve this problem? I CANNOT breakup the SELECT statement into multiple statements.
Thanks in advance

Oracle cannot be configured to give you dirty reads.
Setting your transaction to be READ ONLY probably won't help too much-- the problem here is that when you go to SELECT a particular row, Oracle discovers that the value in the row has changed since the start of your query and the old value is not present in the rollback segments.
How are your rollback segments configured? Perhaps you don't need to allocate additional space to them-- perhaps you can simply increase their OPTIMAL size.
What version of Oracle are you on? If you are on 9i or above, I would strongly consider moving to automatic UNDO management, which vastly simplifies rollback (undo) administration.

Taking rollback segment and datafile offline caused application error

One of the DBA's added a large rollback segment which caused the rman backup to abort. The rollback segment was taking offline and it's datafile was taken offline, all went normally no errors. An Application started gettting errors the database and application were taking down and up, no errors on either but the problem was still there. The rbs datafile and RBS were placed back online and the application worked properly. It looks as if Oracle let us take the RBS and datafile offline with active segments in the RBS is this possible?? If so it means you can pull the rug out from under Oracle and it doesn't even complain

Pls check any transactions written in application level,
explicitly assigned to the RBs which was taken offline.

Alter rollback segment command giving error.

Hi all ,
i am novice to Oracle 9i i am altering rollback segment but getting following error messages.
ORA-30021: Operation not allowed on Undo Tablespace
ORA-25150:Altering of extent parameters not permitted
(in this i am trying to alter maxextents parameter of rollback segment )

Apparently you are using undo segments, as opposed to rollback segments.
You should use undo segments, and they are located in a separate undo tablespace (see the first error message)
Oracle manages the undo tablespace. You can't do anything about it.
However, Oracle is still using 'rollback segment' and 'undo segment' interchangeably.
Likely, your rollback segment is an undo segment, and you can not change it, nor do you need to.

Error:cannot use system rollback segment for non-system tablespace

Hi,
I have created a oracle database 10.2.0 on fedora 9 system. I have created a user and assigned the default tablespace SATYA and given the permissions. But when I create a table in the user I am getting the following error.
Can anyone help me in rectifying this error.

Undo management is either AUTO or Manual, no local
http://download.oracle.com/docs/cd/B19306_01/server.102/b14231/undo.htm#sthref1469
Since you are using 10g, you are recommended to use Auto undo management
If you still plan to use manual undo management, make sure you have other non-system rollback segment in place.

the database is in open mode and the undo_management is set to manual. after i created the locally managed tablespace i ran the script for rollback segment refering to one of the above locally managed tablespace
what other checks do i have to make for creating rollback segment.

Oracle error: Ora-01555 : snapshot too old: rollback segment number 1......

System Error: Unknown Database error (type qqdb_ResourceException) on WMS_WH1: Execute failed for SQL statement ............... error from database is: ORA-01555: snapshot too old: rollback segment number 1 with name "_SYSSMU1$" too small...
Any ideas ? Please help.
Thank you.

You either have
- an UNDO tablespace that is way too small (rollback segments that are too small); or
- an application that does way too many COMMITs (common with apps ported from SQL Server)
From the added info, I would guess that the Java program has a major loop and does processing on each of the values it gets in that loop. At the end of each turn in the loop, it does a commit. Then it tries to look at the next record in the master list. After a while (say around 388 loops ;-) ) it dies.
The reason is that when it looks for information in the master query, it needs to rebuild that information to the moment that query was initiated. It uses rollback (AKA undo) to rebuild that. But rollback is not guaranteed to exist after a commit (unless forced) and once a commit happens, that area can be reused. When it is reused, the information is no longer there to rebuild the row, and that raises an ORA-01555

Error message: snapshot too old: rollback segment number( very urgent)

Hi everybody,
I have a question regarding an oracle error message <b>snapshot too old: rollback segment number</b>.
I get this message when I run a SQL script in Oracle server. To be clear, I wrote the SQL script to extract the data from SAP R3 via Oracle server.
Could somebody please help me with this issue? It's very urgent.
The SQL statement which I use at this moment is:
set undo_management auto
set undo_retention
Please help me with this issue.
Thanks in advance.

it´s very uncommon to have an Oracle version higher than the client versions of the tools.
I suggest:
- Check the note mentioned now several times
- upgrade to a supported newer Oracle release

Hi,
What is the version of Database that is being used ?.
I guess there must be some issue with the database being used, the archive mode or the UNDO segments. As a workaround, you can remove the following command from install.sql and run the sql script again.
