ORA-01555: snapshot too old: rollback segment number with name "" too smal

Hi,
I'm working on Oracle Database 11g Release 11.1.0.6.0 - 64bit Production With the Real Application Clusters option.
I'm exepriencing the error in the subject executing a procedure.
This procedure run at 2am, reading from a table all records written the day before:
... WHERE date_write between d1 and d1+1 ....
d1 = trunc(sysdate-1)So I suppose that the recordset cannot be changed during the execution of the procedure.
The recordset extracs more or less 10milions of records.
The procedure than read few records from another table and then insert a new record into a table (trying to delete it if already existing).
I commit every 10k records.
What I noticed is that the procedure always fails after 1 hour, that's the undo_retention value.
I tried to change the param to 2 hours, and last run failed after 2 hours...
I think I understood the ORA-01555 causes, but I thought the commit would have avoid it.
So, any suggestion?
Thanks in advance!
Samuel

What's then the logic why the commit is causing it?When you commit a transaction, involved undo blocks are "released", and they might be overwritten : if those blocks are needed for consistency, then you get ORA-01555 error.

Rollback segment number not shown with name " not shown " too small

Hi,
we have a table TABLE1 with a BLOB field FIELD1 on a Oracle 10g database. Today we found out that there is one record in that table that make problems. if we try to read the BLOB data from that record, Oracle shows the error:
ORA-01555: snapshot too old: rollback segment number with name "" too small
The strange thing about it, that the message shows neither the segment number nor the segment's name. Like it has lost the reference to it.
Could you help please.
Notes:
The TABLE1 and the BLOB data are really not big.
The UNDO tablespace is 2Gb big and just 1% used.
Thank you very much
Igor

Out-of-row LOB undo is maintained in the LOB segment. So the UNDO tablespace and undo retention is not associated with most LOB ORA-1555 issues. Instead the LOB column is created using either PCT_VERSION or RETENTION to manage how much space within blocks or time transpires before the LOB undo is overwritten. In environments with high updates, deletes on rows including LOBs, the chances of ORA-1555 on LOB undo is very high.
Source:http://blogs.oracle.com/db/entry/troubleshooting_ora_1555
In the above link you will get plenty of good metalink notes to understand and solve the issue.
There is no undo segment name in the error message means this error has no relation with undo tablespace/parameter/segment. This might mean that your LOB table is corrupted. Can you drop and recreate/re-populate this table and try again ?

ORA-01555: snapshot too old: rollback segment number

I getting error while i am taking export one of the table.
EXP-00056: ORACLE error 1555 encountered
ORA-01555: snapshot too old: rollback segment number with name "" too small
ORA-22924: snapshot too old
Export terminated successfully with warnings.
can someone advise me

1) What version of Oracle?
2) Is UNDO_MANAGEMENT set to AUTO? Or are you still using manual undo management?
3) What is your UNDO_RETENTION? How quickly are you generating UNDO? How big is your UNDO tablespace?
4) How long does the export run?
5) Did you specify CONSISTENT=Y in the export? If so, is that necessary?
6) What else is going on? Is it possible to run the export during a quieter period?

SBO Ent XI 3.1 SP3 repository database access error

Dear Experts,
We are installing XI SP3 and using oracle 10g for repository database, we've installed 10.2.0.4 oracle db on windows 2008,
tnsping is working, but we are getting following error ;
Database access error. Reason Loading shared object failed. First tried to load library oci and failed because of error: [%1 is not a valid Win32 application.
]. Second tried to load library oci.dll and failed because of error: [%1 is not a valid Win32 application.
Problems installing Xi 3.1 sp3 with Oracle DB
Same problem solve via using 32bit oracle client, how can i instalee 32 bit oracle client, because oracle path's using ths insttalion directory on same server,
Could you please wirte the steps for how to install oracle client for boe on the same server via 64 bit oracle home
Best Regards

BusinessObjects is not a 64-bit application. It is a 32-bit application that can be run on a 64-bit server. My experience has been that because it is a 32-bit application, it will not work with 64-bit database drivers. For example, we have to set up 32-bit ODBC connections in order to connect to MS SQL Server even though the server where BOE is installed is a 64-bit server.

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.
Regards,
Esrat

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

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: EncryptedLocalStore database access error in AIR 3.4

Hi,
A few of our users were prompted to update to Adobe AIR 3.4 today. After doing this they were no longer able to use our Adobe AIR "desktop" app. I've downloaded the 3.4 SDK and run our app via ADT and I get the following error in the Introspector:
Error: EncryptedLocalStore database access error
Our app stores configuration info in the EncryptedLocalStore.
This has never occurred before and if I uninstall 3.4 and go back to 3.3 the problem does not exist. We need an urgent solution to this because we have hundreds of users who use our AIR app every day. We've told them NOT to update to 3.4 until further notice.
Any assistance would be greatly appreciated.
Brad.

Hello AIR developers,
I want to thank you for your patience and again apologize to you for catching you off guard with this change. Our team met today and our immediate plan is to roll the ELS changes back to the AIR 3.3 level. We are working on a timeline for when this update will be occur. We are treating this with the highest priority and expect it will not take long.
For those interested, here’s how and why this change occurred. Over the past year or two we’ve heard complaints about the reliability of our ELS implementation, especially on the Mac platform. We’ve known all along that we wanted to refactor this feature and remove dependence on third party libraries. We undertook this restructuring during the 3.4 release schedule and finished without hearing any major complaints from our internal or prerelease users. One assumption we made was that ELS data was treated like a volatile cache. In the past we’ve given guidance on the usage of ELS in both blogs and our help documentation, suggesting that developers should not depend on ELS as permanent data storage because it “can be lost for a variety of reasons”. Our position on this hasn’t changed, but we acknowledge and understand that some applications have come to depend on this data and if at all possible, we should do our best to persist it.
Going forward, we will most likely reimplement our changes from 3.4, however when doing this we will also work to provide a way to automatically upgrade and persist your application's data. We will also give plenty of advanced notice and make releases available on our labs.adobe.com site. We want this change to improve your lives by adding improved stability and we look forward to working with you on this in the future.
Thanks,
Chris

EncryptedLocalStore database access error

Hi,
I'm getting "EncryptedLocalStore database access error" when
I tried to save data using EncryptedLocalStore.setItem() on Win XP.
It works fine on Vista. Anyone knows why? The app is signed with a
code signing cert from thawte.
Here is the code that I use:
var profile_username_array:ByteArray = new ByteArray();
var profile_password_array:ByteArray = new ByteArray();
profile_username_array.writeUTFBytes("xxx");
profile_password_array.writeUTFBytes("yyy");
EncryptedLocalStore.setItem("username",profile_username_array);
EncryptedLocalStore.setItem("password",profile_password_array);
Any help is greatly appreciated.

I am trying to store credentials on my linux box using the ELS. I am getting a ELS database access error.But when I checked the Disk the directory is created with the AIR/ELS/<application id>
// My Code to write to ELS.
air.EncryptedLocalStore.setItem("user",(new air.ByteArray()).writeUTFBytes(uname));
air.EncryptedLocalStore.setItem("passwd", (new air.ByteArray()).writeUTFBytes(passwd));
Is it something I need to initialize before I write to the ELS.
Any help would be appreciated.
