Undo error

Hi,
I am getting below error while dropping undo tablespace .
SQL> drop tablespace UNDO_TBS including contents;
drop tablespace UNDO_TBS including contents
ERROR at line 1:

dropping tablespace
I have already created one more undo tablespace and activated it as current.
But still i am facing issue while dropping old undo tablespace.Retention period is 15 mins while is already over .
Please help me in this issue.
Thanks

Aman, just because you only have an undo_retention period of 15 minutes does not mean that no undo data has to be kept more than 15 minutes. You may have an active transaction that has been running for more than 15 minutes. When this process finishes you should be able to complete your command.
You may wish to check on what any active processes that are using the tablespace are. If you have a runaway process or old inactive sessions hanging around you might just be able to kill them, but then again there could be a process you just need to wait out.

UNdo error (ora-01555) - Snapshot too old error

Hi,
If undo get filled and if we get a snapshot too old error then what is the solution for this error, plz give step by step solution for this.

You prevent ORA-01555 errors by
1) Setting UNDO_RETENTION equal to or greater than the length of the longest running query/ serializable transaction in the system
2) Ensuring the UNDO tablespace is large enough to accomodate the amount of UNDO generated over that period of time.
You would need to determine things like the length of your longest running query, the amount of UNDO getting generated, etc. and adjust your UNDO_RETENTION and UNDO tablespace accordingly.

Can anyone help me undo error 999 on yahoo games

I keep getting error 999 on the yahoo games pages. I thought it was the computer goofing up.

There could be a number of reasons. Mine was that the Service Data volume changed. See http://sylnsr.blogspot.com/2013/11/os-x-mountain-lion-server-profile.html
You are going to have to check your logs for specific details though to see if this, or something else applies to your situation.

UNDO Tablespace Issue - URGENT

I had issues with UNDO. Here is what happened -
SQL> alter tablespace UNDO
2 add datafile '/oracle/TESTDB/data04/TESTDB_undo_04.db' size 100M autoextend on maxsize 10000M;
SQL> select file_name,bytes/1024/1024 MB, maxbytes/1024/1024 MMB from dba_data_files where tablespace_name='UNDO';

/oracle/TESTDB/data03/TESTDB_undo_03.dbf 7636 0
/oracle/TESTDB/data04/TESTDB_undo_04.db 100 10000
But after some time this same query gave me this error -
SQL> select file_name,bytes/1024/1024 MB, maxbytes/1024/1024 MMB from dba_data_files where tablespace_name='UNDO';
FILE_NAME MB MMB

Users then started complaining about it.
Queries like this also started giving us these problems -

Random selection/movement/execution of any tool involving mouse click.

Hi nice people, hopefully you have a good day before reading my post.
Since there're already several posts about this issue, I'll save some trouble explaining the issue.

and thanks to slothums, here's a nice video for it :http://digitalmighty.com/random/PSD-CS4-Problem.swf .
Back to my case,here's the system info that might be related:
-All drivers updated.
-CS4 and CS5 both updated to newest version, though issue actually happens regardless whether it's CS4 or CS5, newest patch or a bit old.
-Logitech MX518
-Win 7-32bit/I930/R6950/Asus P6TD/Crucial 4G/Dell 2311H
And here's what I tried before, not solving the issue at all.(i.e. all threads above are not containing the solution)
-Update to CS5, degrade to CS4, update to newest patch, roll back to old one.
-Adjust various options in the preferrence like OpenGL drawing and temp file location.
-Reset the preferrence, reset the plugin or even clear all 3rd party plugin,reset the temporary files folder of the system.
-Purchase a new mouse,try with old graphic card which is R4870 and 8800GT,try with only 2G ram, try with smaller monitor.
-Reinstall the creative suit completely with using Adobe Cleaner to clear all the residual info/files/reg of photoshop.
None of them work, and issue persists.
Generally the issue is like someone pulling you mouse while holding the left mouse key or releasing it against you holding it, resulting a tons of unwanted execution (random box, random erasing, messy brush, expanding or reducing your selection area, namely destroying the work).
There's no precise way of reproducing the issue, though the way I test wheter my action works is by crazy moving mouse and clicking, which sometimes will cause random area to be selected even if I only click the mouse(and actually I invert the mouse and make sure that the cursor is not moving at all)
It's affecting all tools with which you need to have some kind of clicking in it, which consists of most my workload. Literally when it happens, it's cancelling whatever I do and I have to waste same amount of time to get rid of those actions. This is driving me nuts really.
Sorry I can't provide with more details though I know it could be rather usefull if I remembered when I for the first time had this issue and what I did around then
Could anyone shed any light on this issue?

Sounds like you've really been through the ringer with this. I can only imagine your frustration.
Does it only happen ONLY with Photoshop or do you see the same problems with other apps? I really don't think it's a Photoshop problem, given that you're seeing it in two different versions, and that a lot of others virtually never see the problem. Adobe would be out of business if everyone was seeing this kind of mouse madness.
You've updated drivers... Does that include any BIOS updates or driver updates for the motherboard itself?
Have you used a tool like AutoRuns to determine all of what's starting and running on your system?
People with as much trouble as you have often work very long and hard, well beyond a point where they should consider a punt - e.g., wipe the system completely and do a fresh reinstall of the OS, or even go so far as to buy a new computer. I'd probably take the old one out to a deserted spot and shoot it up pretty good, myself. Just remember to keep in mind that your time is worth something. If you spend tens of hours of time trying things, diagnosing things, undoing errors, etc. that's time you could be productive if the problem weren't happening.

A light UndoManager Problem

hi there,
thanks for taking time to read about my problem. i hope you also have enough time to write a solution for me.
the project i'm working at with the JDK 1.4.0 is an GUI-Editor. you can place buttons and textpanes, labels, trees ... all on one big JPanel. the program also supports editing of some properties of the components, so now, after some month work, it look's quite like a real editor.
one of the last features i wantet to implement is a UndoManager that supports adding and removing of components on the panel and if possible supports the change of properties of components. but i failed on implementing the first point, so it shouldn't be to complex to fix my problem:
when i add an component i also add, by using the UndoableEditSupport, one of my own UndoableEdit to a standard UndoManager. i do that every time i add a component. now i want to undo an add. what happened is, that the first component added is deleted (not the last one) ... why?
the next time, after it has deleted the first component, it throws an CannotUndoAction (i think, because the UndoManager wants to undo the UndoableEdit number -1 and that is NULL ). i allready set the isSegnificant attribute on TRUE for every UndoableEdit.
another thing that i want to ask is, if there is another more simple way of doing that?
thanks a lot
wayne

shure ... i have written a class that extends the interface UndoableEdit. my class discribes a constructor that takes some parameters, in example the component that is added, an ID that discribes what what action happened with the component and some more. it also contains an undo()- and a redo()-methode, called, depending on that ID, different submethods that discribe what to do with the component and its parent.
as i understand the UndoManager of Swing, every object from UndoableEdit describes one undo-able user action. if this user action is performed, my application has to generate a new UndoableEdit object and has to transmit it, by using the UndoableSupport, to an UndoManager. if the user performes the undo action in the menu the UndoManager will call the undo()-methode of an these UndoableEdit objects.
what i have done is, that i don't implemented my own version of an UndoManager ... why should i? it just calls this undo()- and redo()-methodes. the order of the UndoableEdit objects in the UndoManager should be like everyone suspects. you add: obj1, obj2, obj3 ... and this is the order the UndoManager has in its Vector-object too. the you call 3 times undo() and he should call: obj3.undo(), obj2.undo(), obj1.undo() ... thats what i had read in the source code of swings UndoManager.
but thats not what happened in my application. i added obj1, obj2, obj3 ... then i called the undo action and the UndoManager calls:
obj1.undo(), error!!!
the UndoManager calls the undo()-methode of the object in his vector that is found on count: 0. the next time he try's to call the methode at -1 and throws an CannotUndoException. i've tried some serinarios with different return values of the methods that deliver boolean values of my UndoableEdit implementing class: isSignificant(), canUndo(), canRedo(), addEdit(...) and replaceEdit(...). but that didn't work.
so were am i wrong??? can somebody help me? if i didn't understand the concept of the swing UndoManager right, tell me were i'm wrong.
thanks a lot :-)

Error Oracle Mobile ORA-30023 Duplicate undo tablespace specification

Hi,
I have the following mobile application (Oracle Mobile 10g R3):
- Win32 (Forms 6i) App.

I have a successfully compilation of my form connected to the mobile database. However when I put a value over a textitem, my WHEN-VALIDATE-ITEM trigger send me an error:
ORA-30023 Duplicate undo tablespace specification
How can I solve this???, It seems like there is a parameter that I have to change.
The WHEN-VALIDATE-ITEM trigger only has a basic select over a "readonly" table.
Please help.
Regards,
Santiago

I think the problem is the following,
I need to convert a date to julian format, example:
to_char(sysdate,'j')
The problem is that it seems like Oracle Mobile connot support this kind format convertion.
So, How can I get the number of days between 01-jan-4712 BC and other date????
I found this function TO_DATE('-4712-01-01', 'SYYYY-MM-DD'), but it doesn´t works on Oracle Mobile.
If someone have any idea about how can I get the number of days between 01-jan-4712 BC and other day without using the format 'SYYYY'......please help

What happens when UNDO space is full? Transaction takes more time to ERROR?

I have a long running transaction (more than 3 hours), and at the same time other operations are occurring on different tables, using the same UNDO space.
Sometimes we see ORA-30036, but this error occurs very late in the process.
The transaction normally takes 3 hours, but when UNDO space is full, we do not get ORA-30036 upto 8 hours or 9 hours of process.
I am wondering what could be happening in the background, when UNDO space is full, whcih makes the transaction to extend upto 8 hours or 9 hours (pl. note, this transaction gets completed within 3 hours normally).
This is in 11g, UNDO space is managed manually.
Any clues? Thanks in advance.

If it is set to non-zero value, Oracle will suspend SQL statement execution if it runs out of certain resources, and running out of UNDO space is one of them. SQL statement execution will be suspended for RESUMABLE_TIMEOUT seconds giving DBA time to fix space issue. Then SQL statement execution will contitue. If issue is not fixed within RESUMABLE_TIMEOUT, statement will fail.

Undo tablespace resize error

Total space occupied by UNDO tablespace is : 3G and used space for UNDO tablespace is only 512M , so approx 2.5G space is free. But when i tried to resize the undo tablespace to 1G then its showing the below error :
ORA-03297: file contains used data beyond requested RESIZE value
but the used data size is 512M only.
Kindly help me to resize the undo tablespace to 1G.

Kindly suggest.
Advance thanks !!

you can't resize undo tablespace. If you are trying to reduce the size.
then add a unod tablespace may like undotbs2 then set undotbs2 as default to your database. then drop the prvious undo tablespace

Undo.cpp line 3067 error when scrolling listbox

In my application, I initialize a LV multi-column listbox as empty (Item Names set as an empty string array). Then I start writing to this property (Item Names), and once in a while, when scrolling down in the listbox, LV crashes and I get an 'undo.cpp line 3067' error. Any ideas? I thought it may be an array initialization problem, so I init it now with a string array much larger than what I plan to write to it. I get the same crash.

vituning,
Are you scrolling around in the multi-column listbox, then deleting all or most of the contents. The error probably happens when you try to undo this action or when you try and scroll the listbox again? If so, before you delete the data, programmatically scroll the listbox to (0,0) or so that atleast valid data will be shown. This should avoid this error.

Snap Shot too old error And UNDO Table space.

I posted [This Question|http://forums.oracle.com/forums/thread.jspa?threadID=718704&tstart=0] in PL/SQL forum. Now thought this would be a better place.
Thanks,
Karthick.

Karthik,
Its actually not the same thing when we talk about manual Rollback Segments and Automatic Undo Segments. Besides the fact that the former is created by us and thus needs to be managed properly in the terms of the size and other things, the later one is far more performance oriented. There are couple of enhancements which are done in terms of Automatic Undo , to quote a few, Undo Stealing is one .Another is the on the fly making the undo segments offfline and while starting up the database, only the needed ones are available . This enables the fast instance startup.
Wont oracle automatically adjust the UNDO_RETENTION parameter based on the UNDO table space size.
If you have read it from Orcle docs than you must have seen this advice is correct when the release is 10.2 onwards and the tablespace is autoextensible. If the tablespace is autoextensible than from 10.2 onwards, you don't need to worry about the undo_retention period. It will be set automatically. If the tablespace is not autoextensible than Oracle would set the parameter value to the duration of the query.
For the snapshot too old error, I would suggest you read this link,
http://asktom.oracle.com/pls/asktom/f?p=100:11:0::::P11_QUESTION_ID:275215756923
There is no other document AFAIK which explains it more clearly than this one.

How to undo typing errors on an iPad?

How do I undo typing errors on my iPad without deleting backwards through several words?
Jean

Manipulating and editing text ....
Hold down on the area that you want to select until a blue line appears. Tap on it again and another pop up appears with the options to select, select all or paste. If you select all, all of the copy on the page or within the text block in which it was created will be highlighted in blue. An option to cut, copy or place appears. Two blue vertical lines will be on both ends of the text block. You can select the blue dot on one of those lines and drag it to select exactly the text that you want to manipulate.
If you choose select - then blue lines will be on either side of that word only. You get the cut, copy, paste or replace options. You can once again drag the lines with the blue dots to select text. If you drag the line to select more text, you get the cut, copy or paste options.
Cut is self explanatory, copy will put that text in the invisible iPad clipboard and you can select another area in your document in which to paste that copy or you can paste into any other document or field that will accept text. Replace is when the iPad will auto correct a word from it's dictionary if the word you have typed does not "make sense" to the iPad.
