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?

Segment creation problem

I have a File to IDoc scenario. The IDoc imported has a particular segment E1EDPAD occuring only once in the structure. I have PRI and QUALF in that segment. For a particular source field X, I need to send the value of QUALF as 3 and then the value of X to PRI. For another source field Y, I need to send the value of QUALF as 7 and then the value of Y to PRI.
The problem is the source IDoc has one occurence of segment E1EDPAD. How do I add a segment the second time in Idoc with the respective values?
The QUALF values are always hard coded. The other values,X and Y change

Hi Madhav,
If I create duplicate subtree option, will it change the structure in the IDoc that I have imported? Will this work at runtime?
--Ideally it will not change the structure, But it serves your mapping rquirement.
Yes, It will work at runtime.
Also what will happen if the value that I created do not come in the source file? Both X and Y are mandatory fields
-- If the the source fields are mandatory it is senders responsibility to send the fields. If you need to avoid error when the fields are not coming then you can use exist func to create the segment.

Sudha

Profitability segment creation problem

Hi,
we have not defined order as a segment level charecteristic, but it is still creating new segment number for every service order settlement, is there any place where i need to maintain settings to avoid creaation of new profitability segment for every settlement.(all charecteristics of a segment are same in every settlement except order number which is not maintained as a segment level charecteristic) but my system is still taking the order number into consideration and creating new proftability segment for every new order. is there any way to fix this issue.

Hi,
please check that you have'nt included the following Characteristics as Profitability segment characteristics:
KSTRG Cost Object
RKAUFNR Order

Rollback segment is filling up during creation of the database

Hi
The Rollback segment is showing around 520mb immediately after
creation of the database after following the wizard provided in
the enterprise manager of oracle. What might be the reason. How
to reduce it. Could any one give me a solution for this matter.
Thanks in Advance.

I tried creating the password file using the following command:
orapwd file=/home/oracle/product/9.2.0/dbs/orapwHR.ora
password=HR entries=5
and got the same error:
ORA-01501 Create Database failed.
ORA-01990 -ERROR opening password file '/home/oracle/product/9.2.0/dbs/orapw'
ORA-27037 Unable to obtain file status.
Linux error: 2: No such file or directory.
Additional information: 3.
Does anybody know how to fix this problem?
Thanks,

Big problem with ROLLBACK SEGMENT

I tried insert into DB Oracle 8i more than 23000 rows from .sql files.
This files contents:
-- START
delete from grls;
insert ..........
insert ..........
insert ..........
-- END
ORA-01562: failed to extend rollback segment ...
My configuration:
CREATE TABLESPACE rbs datafile '$ORACLE_BASE/oradata1/$ORACLE_SID/rbs01.dbf' SIZE 10M;
CREATE TABLESPACE rbs_02 datafile '$ORACLE_BASE/oradata1/$ORACLE_SID/rbs01_02.dbf' SIZE 300M;
CREATE ROLLBACK SEGMENT rbs01 storage (initial 20k next 20k minextents 3 maxextents 121) TABLESPACE rbs;
CREATE ROLLBACK SEGMENT rbs16 storage (initial 20k next 20k minextents 3 maxextents 121) TABLESPACE rbs;
CREATE ROLLBACK SEGMENT rbs_load01 storage (initial 30m next 30m minextents 3 maxextents 10) TABLESPACE rbs_02;
Please help me.

1.)Did you place the rollback segments online
after creation?
Alter rollback segment RBS01 online;
Alter rollback segment RBS16 online;
Alter rollback segment RBS_LOAD01 online;
2.)Did you set your init[sid].ora parameter
ROLLBACK_SEGMENTS = (RBS01, RBS16, RBS_LOAD01) so that they will automatically come on line on istance startup?
3.) You have set up only 304Meg of space for them cumulatively. Is this enough for the 23thousand rows you want to insert?
If not you may want to enable the autoextend option on your datafiles. Of course you will want to change your maxextents. Leaving that value out will give you a default of 505 maxextents.
4.) And finally you could throw in a commit during the insert procedure. This will commit the transaction at that point and clear out the rollback segments for use again.

Rollback segment problem

Hello:
I'm using oracle 8 database and I have a process that generates small transactions (and they're really small), usually this process is executed from 2 or 3 different workstations at the same time, but they don't use the same data sets. The frequency of execution of the small transaction is 10 or 12 a second for each workstation. Each time the process is executed I can count near 6000 transactions, and I always have 2 o 3 of them arising "ORA-01562: failed to extend rollback segment number n" error. Since the transaction uses a small space of the rollback segment I can't find an explanation to this behavior. Is this related to the time between transaction and the freeing of the unused rollback segment ? I would really appreciate if somebody could help me!!!
Thanks in advance, Javier Petrozzi

It appears to me that some of the transactions remain open for quite some time and the new transactions are not able to obtain an extent for the rollback segment.
The following query gives some useful information.
1 select s.sid, s.username, r.name "SEGMENT NAME"
2 from v$session s, v$transaction t, v$rollname r
3 where s.taddr=t.addr
4* and t.xidusn = r.usn

Rollback segment problem during import

Hello experts,
please help.
I have the following error when importing table data to my
Oracle 8.1.7 database.
IMP-00058: ORACLE error 1562 encountered
ORA-01562: failed to extend rollback segment number 16
ORA-01237: cannot extend datafile 3
kind regards
Yogeeraj

alter the tablespace which contains rollback segments, and
either change the existing datafile (datafile 3) to autoextend
on or resize, or add new datafile in another disk drive which
has more space (it is better to set autoextend on or give it a
larger space).

Rollback segment for index creation

Hi,
I want to assign a specific (big) rollback segment to the transactions used by InterMedia Text while creating the index.
However a 'SET TRANSACTION USE ROLLBACK SEGMENT create_index' directly before the 'CREATE INDEX ...' seems not to work, as I saw that the inserts performed by InterMedia Text (e.g. into the $i and $k tables) were done using other rollback segments (e.g. RBSxx).
Is there any way to InterMedia Text to tell which rollback segments it should use for its internal operation?
Cheers,
Johannes

we can't assign the rollback segment to particular user.
For better performance place different table
spaces in different disks.

Database creation problems and parition consolidation

This is my first time on here so please look past my green-ness. =)
I Installed Oracle 8.1.7 successfully and opted to setup the database creation later so I could put the database on another partition. Well, I tried once to create the database on the partition I installed oracle onto (/oracle) but I had insufficient space, It said I needed 1.3 gigs. My "/database" partition is only a 1 gig parition (and /oracle is 2 gigs). My plan was of course, to seperate them.
Ok, I didn't see an option to create the db on another partition so I resigned to using /oracle. My question now is, is the 960 megs on /oracle enough to create the database? I used the custom setup so I could see how everything was broken down and I noticed that my rollback segment is 500 megs. Is this necessary? Can I get by with 100 megs and be fine? Also, if I did do this, I'd have approximately 100 megs free for data, this is enough I hope??
Lastly, I need to combine the partitions somehow without effecting /. The hard drive is broken down into:
gigs
5.5 /
2.0 /oracle
1.0 /database
Does anyone have any ideas? In windows, I used partiton magic but I don't know if there is a linux version.
One more thought (last one for real =), it had 50 megs allocated for it's shared memory pool. I'm assuming this will take away from the 128megs I have thus effectively making only 78 available to X, will this cause any noticeable problems other than a bit of slowdown? I have most if not all of my virtual memory free at all times. I know I should get more ram, but you know how the budget thing goes...
Any help would be greatly appreciated,
Rob

Try running the catalog and catproc sql scripts.
$ cd $ORACLE_HOME/rdbms/lib
$ svrmgrl
connect internal
@catalog
@catproc
That will set up all of the internal views and packages that
oracle needs to do DDL.

Database creation problems

Help!! I have installed 8i on RH Linux 6.1 and followed the "Friendly" guide steps, it worked perfectly. However when I try to create a database using the Database assistant, I get an error "Oracle Not Logged on" I've reinstalled twice and still have the same problems - can anyone help?
Thanks for any suggestions/help!
null

This problem doesn't just occur on Linux. I have encountered the same on both Digital Unix and HP/UX. I finally gave up and told it to just create the scripts. Looking at the scripts, there are a number of different problems depending on the items that you choose to install and/or customizations to db setup, such as size and placing of files.
To find them, I generated the scripts and then looked at the contents and used svrmgrl to individually run commands so that I could see the "real" error message.
It's been awhile but I think the not logged on was a failure in the initial create database command... Or maybe it was the MAX_ENABLED_ROLES being too small in the default init file to support some of the products... Or the rollback segments being created as private and not being automatically added to the init before the assistant does a shutdown and restart... Or it creating the rollback segment tablespace not the size and parameters that I requested...
You may guess by now I wasn't too impressed by the dbassist program. All I can say is doesn't anyone believe in testing anymore? I have a hard time believing that anyone at Oracle actually tested running this product and actually using any of it's features.
This really pissed me off because when I first saw the pretty GUI and nice interface I thought WOW, this is great, finally something to make database creation simpler than running all those commands and scripts.

Help me regarding Rollback Segment!! It is Very Very Urgent.

My Oracle Version is 8.1.5.0.0
I have created my Database with one Data File and after creating of the Database I have found that my Database is having one Tablespace and then name is "System" and I have also found that a Rollback Segment is also created by Default on The "System" Tablespace and the name of that Rollback Segment is also "System".
Then what I did, I did create another Tablespace name "HR" with the help of the following syntax:
CREATE TABLESPACE HR
DATAFILE 'E:\MANODATA\U5\HR01.DBF' SIZE 100M
EXTENT MANAGEMENT LOCAL UNIFORM SIZE 256K;
Then I tried to create a Rollback segment on the "HR" with the following syntax:
CREATE ROLLBACK SEGMENT HR_RS TABLESPACE HR;
Tablespace is not created but I am getting an error, which I am mentioning below:
Cannot Use System Rollback Segment For Non-System Tablespace 'HR'
Then what I did, I did create another Tablespace name "USERS" with the help of following syntax:
CREATE TABLESPACE USERS
DATAFILE 'E:\MANODATA\U4\USERS01.DBF' SIZE 10M
EXTENT MANAGEMENT DICTIONARY;
Then what I did, I did create a Rollback segment on the Tablespace "USERS" with the following syntax:
CREATE PUBLIC ROLLBACK SEGMENT USERS_RS
TABLESPACE USERS
STORAGE (
INITIAL 50K
NEXT 50K
OPTIMAL 750K
MINEXTENTS 15
MAXEXTENTS 100);
Then what I did, I again tried to create a Rollback segment on the "HR" with the following syntax that you provided:
CREATE ROLLBACK SEGMENT HR_RS TABLESPACE HR;
Now the Rollback Segment is created without any problem.
Now Please tell me why it is so happening. I am very much confused of all this. Can't I create any Rollback Segment on a Locally managed Tablespace unless and until I do not Create a Dictionary managed Tablespace and unless I don't create a Rollback Segment on that dictionary managed Tablespace? Is there any restriction in my Version of Oracle (8.1.5.0.0)?
Please help me in this matter as soon as possible.
Thanking You,
Manojit.

Thanking You,
Manojit. Manojit -
Maybe too late but here goes anyways -
You need to have another SYSTEM Rollback segment before you begin the process you mention above. At this stage of developing your database, the SYSTEM tablespace will keep the one rollback segment for it's own use and you need another one to create rollback info in for other objects. Create another system rollback segment in the existing rollback tablespace, then create a separate rollback tablepace with extent management local, then create some rollback segments. You may even want to use the SET TRANSACTION USER ROLLBACK SEGMENT RBS2 for the creation of the new Rollback Tablespace. Then you can continue with the creation of other objects.
Hope this helps,

Pb with rollback segment

Hi guys.
Am using oracle 8i and am having problems with rollbackup segment. My rbs tablespace is 35GB and will like to shrink it! Its a production db, so my question is shoudl I fire the below query?
alter rollback segment SYSTEM shrink;
alter rollback segment RBS__BIG shrink;
alter rollback segment RBS01 shrink;
alter rollback segment RBS02 shrink;
alter rollback segment RBS03 shrink;
alter rollback segment RBS04 shrink;
alter rollback segment RBS05 shrink;
alter rollback segment RBS06 shrink;
Is there any downside? Please advice.
Thanks.

Hi Friend,
Production DBs are always having big transactions, These transactions obviously hold large memory in rollback segments. You will not face any issue after srinking it but if any transaction is failed and it has not been enrolled or flush out from your rollback segment. You will be not able to recover the data from rollback segment. I would suggest use share table space here instead of shrinking it. Atleast it will help to to recover current transaction in case of calamity.
Thanks,
Nitin joshi

Rollback Segments

Hello all,
I am hoping someone can help me. I have a dev and prod
instance, with identical rollback segment specs. The problem I
have is that I am running out of space on one of my instances
(dev). The prod instances rbs's are all the same size while the
dev instance rbs's are all over the place. One rbs (in dev) may
be at 10mb and another at 800. I don't know why the size
doesn't reduce after I issue a commit. I think the problem is
that the rbs's for both instances are public and one set of
rbs's is only being used. Can any offer any suggestions? Thank
you!

I would like to suggest 2 things :
1) make all rollback segments to same size
2) set optimal storage parameter of rollback segment.

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.
