Illegal rollback Segment operation in Automatic Undo mode

Hi,
I use oracle database 9.2.0.1 and I try to install SCM repository but when I run ckcreate I saw an error message in
the log file that Illegal rollback Segment operation in Automatic Undo mode because oracle 9.2 use automatic undo mode .So how can i install the repository.

You have hit bug '2108361'. I think you could safely ignore it in your case.

ROLLBACK SEGMENTS OPERATION

Hello Everyone
This is the first time I am a forum member and I'm figuring out how it works because I have a very big problem
Look, I'm a support engineer and, as you know, the code of the application is not own by me.
Three weeks ago I received a report which is related with the Rollback operation.
There's a process which delete old data from my database and, normally, this process has three parts, as shown in the alert_dbinstance.log:

It seems you should look here:
ORA-1636 signalled during: alter ROLLBACK SEGMENT CLEANUP_RS0 ONLINE...
Looks like you have ORA-01636 error:
rollback segment 'string' is already online
I suggest you check Oracle documentation about this error. Seems to me your process try to access rollback segment that is already in use.

Rollback segment creation problem

When i try to create rollback segment on oracle 9iRelease2 database in linux operating system, i got the following error, ORA-30019: Illegal rollback Segment operation in Automatic Undo mode.
I have already modified Undo_management as manual in init file.
How can i solve this problem?
Thanks

In SQL*Plus, can you check what your undo_management is set to, just to verify that it is picking up the change?

Create rollback segment

Anyone knows why I can not create rollback segment in 9i?? I
used same script in 8i and it works.
"create rollback segment lims_rollback tablespace lims_rollback;"
ERROR at line 1:
ORA-30019: Illegal rollback Segment operation in Automatic Undo
mode
what is automatic Undo mode???

Automatic undo mode is the default behavior in Oracle 9i where
Oracle server itself manages creation/sizing etc of rollback
segments. I believe if you want to do it the old 8i/8/7.x way,
you need to change some parameter to not use Automatic Undo

Undo segment & Rollback segment

Hi,
What is the difference between Undo segment & Rollback segment?Is it a standard practice of creating roll back segments for each tablespace?
Regards,
Cherry

What is the difference between Undo segment & Rollback segment?
Undo Mode
Undo mode provides a more flexible way to migrate from manual undo management to automatic undo management. A database system can run in either manual undo management mode or automatic undo management mode. In manual undo management mode, undo space is managed through rollback segments. In automatic undo management mode, undo space is managed in undo tablespaces. To use automatic undo management mode, the database administrator needs only to create an undo tablespace for each instance and set the UNDO_MANAGEMENT initialization parameter to AUTO. You are strongly encouraged to run in automatic undo management mode.
Is it a standard practice of creating roll back segments for each tablespace?See above and http://download-uk.oracle.com/docs/cd/B19306_01/server.102/b14220/logical.htm#sthref449

Rollback segments using UNDO Tablespace?

First, I created a database for a vendor with an Undo Tablespace UNDOTBS. Then the vendor requested me to create rollback segments instead. So I created a new tablespace RBSTBS just to hold these segments. When I tried to create the rollback segment using the newly created tablespace RBSTBS, it complained that I am not allowed to use non-system tablespaces.
So instead, I used the Undo tablespace UNDOTBS to hold the rollback segment. It worked.
Am I really allowed to use the UNDO tablespace to hold rollback segments? Can't I use normal tablespaces for rollback segments?
Another thing, the vendor wanted me to create rollback segments of 200MB each. Where do I set this while creating the rollback segment? Is this the INITIAL, NEXT, or OPTIMAL size?
I know that Oracle recommends using UNDO rather than rollback segments. Is there any advantage in using traditional rollback segments?
Thanks for any help!

Advantage with rollback segment is you can force your transaction to use any specific rollback segment, where as with undo you don't have any control. Oracle does it for us.

USING DEFAULT LOCAL ROLLBACK SEGMENT

Hi,
DB Version is 10.2.0.4
Recently Noticed a MV refresh taking various time to complete. The MV refresh starts at 9pm and completes some time at 1am or 12am are sometimes very fast at 10pm. The number of records are almost same. There are no locks in the db during that time.. Opening the MV script i could see
REFRESH COMPLETE
WITH ROWID
USING DEFAULT LOCAL ROLLBACK SEGMENT
DISABLE QUERY REWRITE ASUsing default local rollback segment - is that allocation of rollback segment causes this
Referred the manul
http://download.oracle.com/docs/cd/B19306_01/server.102/b14200/statements_6002.htm - where it says this clause is not valid if the DB is in automatic undo mode.
thanks,
baskar.l

Rollback segment is a concept from Oracle 8i where it last showed up. This clause is preserved only for upward compatibility, but it is obsolete.
On the other hand, why do you worry about rebuilding the complete MV? either way you perform a full refresh, not a fast refresh.
If you are concerned with the time it takes to be full-refreshed find out if it is possible to have it in fast-refresh mode, tune the underlying query and make sure there are no other concurrent processes negatively affecting the I/O throughput.

SYSTEM Rollback Segment bad

I ported a database over to a new server.
It seems there may be transactions pending...which I don't care about.
I can log as SYS and run queries, but I cannot run DML or DDL statements.
I have narrowed down the problem to the SYSTEM rollback segment.
I am running in Automatic Undo mode.
How do I clear transactions from a rollback segment?
I don't think I can alter or create a new SYSTEM rollback segment.

There is no error message.
When I issue any DML/DDL statement Oracle just hangs forever...and never issues an error message.
Here is the latest printout from the alert.log file:

Rollback segments - database logging

Got a problem...
We are trying to move data from one database to another using: INSERT INTO table1 (SELECT a,b,c FROM table2@db2). The problem we are having is that the amount of data being moved with this in sert command is too great - we are getting an error indicating that our rollback segment is not large enough - ORA-01562: failed to extend rollback segment number 4.
Unfortunately, we are not going to be able to increase the size of the rollback segment any further than we already have. Is there a way to disable the database logging that occurs?
I tried using INSERT INTO table1 dbms_disable_logging (SELECT a,b,c FROM table2@db2), but noticed no difference - same error.
Any ideas?
Thank you,
Dan

We use select..into all the time in an unlogged mode for speed and rollback space reasons.
We replicate fifty million row tables with a minimal amount of rollback segment (<50MB).
In unlogged mode we can replicate 50 million rows in under forty minutes - that's smokin!
Oracle version 8 or greater introduced this concept. I am running 8.1.6.
You need to alter the table to disable logging and then perform the select into.
The table alter only takes seconds.
ALTER TABLE IDMDBO.DIM_PLANS NOLOGGING
Then do the select into and then turn logging back on (if so desired).
You can also disable logging at the table space level.
Keep in mind there are only a few database operations that can be performed unlogged and select..into is one of them.
There is currently no way to carte blanche disable transaction logging - hopefully this will be coming soon!
Cheers.

TRANSACTION을 ROLLBACK SEGMENT에 할당하는 방법(SET TRANSACTION USE)

제품 : ORACLE SERVER
작성날짜 : 2003-04-04
TRANSACTION을 ROLLBACK SEGMENT에 할당하는 방법
==============================================
(SET TRANSACTION USE ROLLBACK SEGMENT)
Purpose
Batch job 등을 사용할 때 특별히 크게 만든 rollback segment를 사용하도록
할 수가 있다. transaction에 특정한 rbs를 지정하는 방법을 알아보자.
Explanation
Oracle은 다음과 같은 규칙에 의해 각 Transaction이 사용하는 Rollback
segment를 결정한다.
1. Active Transaction의 수가 가장 작은 Rollback Segment에 할당한다.
2. 만약 1의 조건에 만족하는 Rollback segment가 하나 이상이면, 가장
마지막에 할당된 rbs 다음의 rbs를 할당한다. 이것은 undo 기능을 더
오래 지속시키도록 해 준다.
그러나, Application이 큰 rollback segment가 필요하다면 위와 같이
자동적인 rollback segment의 할당이 아닌 Manual하게 특정 rollback
segment를 할당 가능하다.
다음의 방법을 사용한다.
1) 큰 rollback segment를 만든다. 큰 rollback segment 를 만들기
위해서는 rbs tablespace에 영역이 충분히 커야 하므로 필요할 경우
tablespace를 확장하는 작업을 한다.
<tablespace 확장>
$ sqlplus system/manager
sql> alter tablespace rbs add datafile '?/rbs1SID.dbf' size 100m;
<rollback segment 생성>
sql> create rollback segment big_rbs storage(initial 10m next 10m)
tablespace rbs;
sql> alter rollback segment big_rbs online;
2) Transaction 를 assign 한다.
<sqlplus>
SQL> set transaction use rollback segment big_rbs;
<pro*c>
exec sql commit work;
exec sql set transaction use rollback segment big_rbs;
<forms>
dbms_transaction.use_rollback_segment('big_rbs');
이와 같이 지정하면 이후에 commit 또는 rollback이 일어날 때까지
한 transaction에만 해당된다.

Difference Between Rollback Segments and UNDO Tablespace

Hi guys,
Can you tell difference between Rollabck segments and UNDO Tablespaces.
I think that rollback Segemnts and UNDO tablespaces are similar both are used for storing before imags of data, which is going to be modified.
but my question still both the rollback abck segments and UNDO tablespaces exists.
why and what is the reason of both existing and at what time, we can use..them at which scenarios's
Regards,
Pavan Kumar N

Undo segments in undo tablespaces, introduced in 9i, are the successor of rollback segments.
They are automatically managed by Oracle.
Rollback segments exist for reasons of backwards compatibility.
That said, you should switch to undo segments and stop using rollback segments.
Other than that: could you please avoid rehearsing the complete documentation in this forum?

Cannot drop old undo tablespace. Cause: active rollback segment

dear all.
db: oracle 10.2.0.1
os: rhel as version 5 64 bits.
This is a testing database. And my database is online and open. But i can free the external usb disk that contains my ols undotbs.
I want to drop old undo tablespace but this is not possible.
1.- In order to open my database i had my datafile( '/mnt/hdext/back_plelds/undotbs02.dbf') offline drop, and then i can to open my database.
2.- When i try to delete my old undo tablespace im getting this error:
SQL> drop tablespace undotbs1 including contents and datafiles;
drop tablespace undotbs1 including contents and datafiles
ERROR at line 1:
ORA-01548: active rollback segment '_SYSSMU1$' found, terminate dropping
tablespace
3.- My default undo_tablespace is another that i was created before step 1.
SQL> sho parameter undo_ta
NAME TYPE VALUE
undo_tablespace string UNDOTMP
SQL>
Well i search in metalink ORA-01548 code error and in 18947.1 doc whows me that the solution is:
Action: Shut down instances that use the active rollback segments in the
tablespace and then drop the tablespace.
4.- I try to shutdown but im getting:
SQL> shutdown immediate;
ORA-00376: file 10 cannot be read at this time
ORA-01110: data file 10: '/mnt/hdext/back_plelds/undotbs02.dbf'
SQL>
This /mnt/hdext is an external USB disk and i have all permissions. I exported tables without any problem and i can read all files.
i search un metalink again ora codes (ORA-00376 ORA-01110) and the doc id: 427801.1 shows in the solution:
Drop the old undo tablespace instead of making it offline.
but when i try to drop the tablespace it shows the error describe in the step 2.
Facts:
- my tablespace UNDOTBS1 is ONLINE. I put in offline and this is not the solution.
- This is the status of my rollback segments:
SQL> select segment_name, status from dba_rollback_segs where
2 tablespace_name='UNDOTBS1';

i cannot drop the rollback_segment
What can i do ???
thanks a lot.

in step 4 did you try with shutdown abort?
If its still does not work then create another new table space with new file and then swtich to that tablespace http://download.oracle.com/docs/cd/B19306_01/server.102/b14231/undo.htm#sthref1504Khurram

Replacing explicit Rollback Segments by UNDO segement

Hi,
My DBA wants to turn off the explicit rollback segments currently being used and replace them by UNDO segment. I have explicit mention of these rollback segments in my C++ and Pro*C codes. What changes am I supposed to make in order to implement the UNDO segements. Do I need to remove the function or only commenting the rollback segment reference line will suffice. Please see the sample code below:
void DeleteDBI::SetTransaction()
struct sqlca sqlca;
EXEC SQL BEGIN DECLARE SECTION;
// Thread context:
sql_context ctx = dbConnection->GetContext();
EXEC SQL END DECLARE SECTION;
EXEC SQL CONTEXT USE :ctx;
EXEC SQL SET TRANSACTION USE ROLLBACK SEGMENT RBS_LARGE_02;
EXEC SQL WHENEVER SQLERROR DO SqlError(sqlca, "DeleteDBI::SetTransaction");
}

It looks like you can comment the entire procedure.
However it is not a good practice to control the Rollback segment from code.
Check with ur DBA for better options in the future.

Oracle9i How to convert from undo tables to rollback segments

Hi,
Anyone try before converting from UNDO management to using rollback segment....What are the procedures for the conversion...
Thank You...

Hi,
Follow these steps to convert from Auto UNDO to Rollback Segs....
1. With the database opened, create a rollback tablespace and then create some rollback segments and bring them online like this
CREATE ROLLBACK SEGMENT RBS1 TABLESPACE RBS;
ALTER ROLLBACK SEGMENT RBS1 ONLINE;
2. Then edit the PFILE and modify these parameters
Add: ROLLBACK_SEGMENTS=(RBS1,RBS2,RBS3....)
Comment: UNDO_MANAGEMENT=AUTO and UNDO_TABLESPACE=UNDOTBS or whatever name you have for your UNDO tablespace.
3. Shutdown the database gracefully(normal).
4. Startup pfile=<Pfile path>
5. Sync these new parameter changes to the SPFILE by recreating the SPFILE.
6. Take a full level 0 backup of your database as the structure has changed.
The next time you start the database, it will use the SPFILE which is same as the PFILE.
Regards.

Tablespace, Rollback segments and Undo tablespace

hi,
we are frequently getting an error on tablespaces, rollback segments and undo tabelspaces during the ETL load. This was really distrubing us to go further, is there any best practice how to avoid the tablespace errors or any precautions to be taken, we are very new to this ETL loads, pls advice
Kishan

Hello Kishan
Yes. Make tablespaces bigger. However, the proper way to do it is optimizing your queries. If you don't have experience with Oracle DB, consult your DBA.
Hope this helps
