DEADLOCK DETECTED - DELETE statement - how/why he expects in SHARING mode?
HelloI wonder if anyone can advise here. The environment is:
Microsoft Windows 2003 Server
Standard Oracle 10.2.0.4 Edition
We had a deadlock detected in our application on a customer site - I enclose the corresponding part of the trace file below. While we think we have found the reason for the deadlock (looks like it is due to a foreign key in cascade), I'm confused as the lock mode that is requested.
Here is the track information:
Deadlock graph:
---------Blocker(s)-------- ---------Waiter(s)---------
Resource Name process session holds waits process session holds waits
TX-00120012-00003b59 28 475 X 29 481 S

Rows waited on:

Session 475: obj - rowid = 00014625 - AAAUYlAAIAAAAawAAo
(dictionary objn - 83493, file - 8, block - 1712, slot - 40)
Information on the OTHER waiting sessions:
Session 481:

action name: our_action, hash value=3631189430
Current SQL Statement:
DELETE FROM TABLE_1 T WHERE T.T_ID = :B1
End of information on OTHER waiting sessions.
Current SQL statement for this session:
UPDATE TABLE_1 T SET T.STATUS_ID = :B2 WHERE T.T_ID = :B1
It seems to me like session * 481 * trying to do a deletion when the block is raised: DELETE FROM TABLE_1 T WHERE T.T_ID = :B1
and ask which mode (dynamique31) S . ---------Blocker(s)-------- ---------Waiter(s)---------
Resource Name process session holds waits process session holds waits
TX-00120012-00003b59 28 475 X 29 481 S
(also the 'no line' for lines didn't wait)Session 481: no row
I thought it would be in mode (e) X (clusive) (for the line being deleted). Actually Yes, I set up a test of fast and simple locking and mode (e) X (is) expected the final delete .So, am I misinterpreted the tracing information, or is the DELETE statement requesting the lock in mode S (Hare)? If this is the case, I'd appreciate a quick explanation of how/why it's...
Kind regards
ADOS
I think we have almost the same reason to wait in S mode as in [single key application | http://books.google.pl/books?id=14OmJzfCfXMC&dq=oracle+wait+interface+practical+guide&q=unique+key+enforcement].
If two sessions want to insert the same key value, the other must wait, because the outcome depends on a commit / rollback of the first session. In the case of validation, session 2 must generate an error in case of cancellation, it must insert his record.
In the test provided by ADOS, at session 1 there is an insert in session 2 - delete. The result of the delete operation depends, once again, commit or rollback in the first session. In the case of validation, it must remove, and cancellations, there is nothing to remove.
If the insert in session 1 has been replaced by the Update, there is no S lock but 'normal' eXclusive

ORA-00060: Deadlock detected while you wait the cursor CLOSE resource
Hello
I am a new Member of this forum. I work with a problem that we have obtained a few weeks ago. It runs in the lot C Pro executable on 10 threads dealing with > 800 data accessed from more than one table. The error, such as reported was a package.function call.
This is the error I encountered:
process_item ~ G *, D * ~-60 ~ ORA-00060: Deadlock detected while you wait resources ~ PACKAGE ERROR = cursor CLOSE C_ * in the R package *. I * 7641
The slider is a simple SELECT without Table or record locking.
My questions are:
* During the occurrence of this error, execution is already in the line of the CLOSE cursor or did the error has occurred between the OPEN and the CLOSE slider? There are several lines of code between the OPENING and CLOSING:
-one who calls to a package.function that simply stores the values of parameter to a variable
-another one that retrieves the cursor. The group that contains the values of the cursor is used only by a single function in the package
* Is it possible for this CLOSE cursor cause a deadlock? What could have caused this?
* From what I know, Oracle treats blocks by abandoning the blocking process, while others continue, but this impasse caused our program to hang. How is that possible? The origin of the impasse might be our Threading program? This is a rare event and has past that twice this year.
Thank you

I see, so it be that blocking has occurred before the CLOSE cursor or it occurred during CLOSING? The cause could be executable ProCfirst cause is NOT ProC

first cause is NOT PL/SQL.
cause of ORA-00060 is DML (INSERT, UPDATE, or DELETE)

Need help to set a DELETE statement.
I have a table that contains the records of files. Files come in a bouquet each week. So, we need to delete records from a table to the corresponding fields and load the table with up-to-date data.
In doing so, the DELETE statement takes a long time. Need help with this setting.
Here are the details.
(1) total number of records in the table: 23 million records.
(2) approximate records deleted each time: 500 K to 1.5 million.
(3) table is partitioned on a PERIOD key. That is, each partition will have the data for a given period.
(4) table is not indexed
(5) removal occurs on a combination of 2 fields (PERIOD + BATCH).
Here is the query and the plan:

Need your suggestions on how the query / table can be tuned.Hi Anand,
I wanted to check why your tkprof Watch report two executions of the statement:
call count cpu elapsed disk query current rows ------- ------ -------- ---------- ---------- ---------- ---------- ---------- Execute 2 2315.71 2480.17 0 3351 624489 611765
In fact, it there was only a single execution of the DELETE statement. The trace file begins with a call EXEC of any statement without call analysis
*** TRACE DUMP CONTINUED FROM FILE XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX_ora_241708.trc *** EXEC #1:c=20000,e=13996,p=0,cr=0,cu=0,mis=0,r=0,dep=0,og=0,tim=32472879711702 ===================== PARSING IN CURSOR #2 len=68 dep=0 uid=72 oct=42 lid=72 tim=32472883567994 hv=740818757 ad='0' ...
TKProf aggregates this EXEC call with call EXEC of the DELETE statement because they have the same location of cursor (#1), he thinks it was the same cursor.
PARSING IN CURSOR #1 len=93 dep=0 uid=72 oct=7 lid=72 tim=32472889974030 hv=1242910589 ad='e5979d80' DELETE from detail_unknown where n_per6 = 201214 and FLBATCHID = 'PCAFRINTERMAR1105' END OF STMT PARSE #1:c=0,e=11462,p=0,cr=0,cu=0,mis=1,r=0,dep=0,og=1,tim=32472889974024 ... EXEC #1:c=2315710000,e=2480213492,p=0,cr=3691,cu=624489,mis=0,r=611765,dep=0,og=1,tim=32475370187626
So, the question about two executions is closed - there was only a single run.
The performance - 2315,71 seconds of time processor is absolutely huge for such amount of work. It looks like a bug.
First, I propose to check the time without compression. If your environment allows this kind of testing try to decompress the partition and re - run on unpacking data DELETION.
10.2 find the name of the partitionselect partition_name from dba_tab_partitions where table_name = 'DETAIL_UNKNOWN' and partition_position = 6
After that
alter table DETAIL_UNKNOWN modify partition
nocompress; alter table DETAIL_UNKNOWN move partition ; and run again the button DELETE.
What is the operating system on the server?

It will cause any problem?
What should I do?Hello..
This lock will be automatically released. If you encounter a lot of blocking issues, you can increase the INITRANS of this parameter. We also had a blocking problem on a production database, we found was due to a trigger. So, you can also check the triggers.

Original title: problem display forms in PDF format after connecting to the site of Governor
Hey Ern,
Thanks for posting your query in Microsoft Community.
I imagine the inconvenience that you are experiencing and will certainly help you in the right direction to solve the problem. However, I would be grateful if you could answer a few questions to refine the question in order to provide you with better assistance.
- You made any hardware or software changes the computer recently?
- You have a wired or a wireless connection?
- You have a router connected to the computer?
The question could arise if it is missing or damaged Internet Explorer files that the display of the script on the page or if the Hosts file is damaged or contains incorrect information. To resolve this problem, I would suggest trying the following methods and check if the problem persists.
Method 1:
Try to start the system in safe mode and check if the number is reproduced. If this isn't the case, then clean the computer starts and check if that helps.
Step 1:
Safe mode is a diagnostic mode in which you are connected with only the minimal necessary services and active pilots. Check if the number is reproduced.
Start your computer in safe mode
Note: In the advanced startup options, select safe mode with network .
Step 2:
Put your system to the clean boot state helps determine if third-party applications or startup items are causing the problem. You must follow the steps in the article mentioned below to perform a clean boot.
How to perform a clean boot in WindowsNote: See "how to reset the computer to start normally after a boot minimum troubleshooting" to prepare the computer to start as usual after a repair.
If the problem persists, try the following method.
Method 2:
Read the following article and check if it helps.
Get help with the Web site (HTTP error) error messages.
If the problem persists, try the following method.
Method 3:
- Go to Start, click all programs and open the Accessories.
- Right-click on command prompt in the list programs, and then select run as administrator. If you are prompted for an administrator password or for confirmation, type your password, click OK, or alternatively click on Yes.
- In the command prompt, type the following commands and press ENTER after each command:
ipconfig/release
ipconfig/renew ipconfig/flushdns - Close the command prompt and restart the system.
See if the problem is resolved.
If it is not resolved, follow these steps if you are connected to a router.
- It turn off, unplug, unplug it and wait 5-10 minutes.
- Shut down the computer.
- Wait 5 - 10 minutes.
- Reconnect the router, restart the router and don't plug it in yet.
- Start your computer, connect to Windows and connect the router to the computer.
- Try to connect to the Internet.
If the problem persists, try to update the firmware on the router, you can get this update from the manufacturer's Web site.
Hope this information is useful. Let us know if you need more help, we will be happy to help you.

Delete apDivs. Why they remain in the code?
Recently, I noticed that when I delete an apdiv of a page in design mode the apdiv remains in the code. Why is this? I'm successfully delete?
Scott2001 wrote:
I do not understand the chaos that occurs when the removal of the code. I have a few times removed the code for the APDivs that I removed his mode of design and everything seems to work perfectly on all I tested it across browsers. Could you please develop what the problems are that might happen to do this?
CSS is used to style HTML. We will say that I have created a complex style for a particular div rule, but decided I want to move the div to a different location on the page (I mean not APDivs, but any div). If deleted automatically Dreamweaver CSS attached when I cut an element from the code, it would be a disaster. In addition, most sites that use CSS store style rules in an external file. If the rules associated with an element have been removed while the element, the rules would be more available in the remaining pages.
Of course, when you draw an APDiv directly in Design view, it adds the CSS in the head of the same page. So it would not create a problem if the rule was deleted in these circumstances. However, Dreamweaver is of opinion that he should not touch the style rules that have already been created. He expects you as the developer to know what you are doing and what the code is for.
If your sites consist of a large number of elements of a fixed size, you reach not too bad off with absolute positioning. It can work very well with the images, but it is not a tool of good layout for the vast majority of Web sites. The web is a liquid medium. It doesn't have the luxury of fixed page sizes you get in print.

I'm looking to find out how to detect the State of the animation. Specifically, it has stopped playing or reached the end of the animation. I do that in Actionscript code? or I can detect it with of html or javascript code on the page that incorporates the animation?
For example. I use JDIC to open a browser window to play the animation. When the animation runs its course I want to window to close. I can detect the end of the animation on the imbedding page?Maybe try to create a new shell swf that loads other SWF files when running. You can add your Detection to this file to know when the animation ends and close the window if necessary.

I was always able to delete cookies in Firefox. With the latest version, I don't see a delete button or move the slider to display a button Delete. How to delete cookies without a button actually remove visible?
How do you remove usually cookies? In the Firefox Cookies dialog box, there are two buttons at the bottom: all delete and delete the selection. If you're used to a button Delete, it could be that you used an add-on to delete cookies.
You can access the dialog box Cookies for the current site using the Page Info dialog box. Either:
- Right click and select View Page Info > Security > "View Cookies".
- (menu bar) Tools > Page Info > Security > 'view the Cookies '.
- Click on the globe or padlock icon in the address bar > additional information > "View Cookies".
In the dialog that opens, the site current is automatically entered in the top search box, so you can delete cookies from the site individually. If you want to see all THE cookies, you can disable this dialog.

I have mozilla firefox in my programs, I accidentally deleted it how I set in the program?
Hi RUBYFRUIT,.
Did you delete Mozilla Firefox in the Menu start "all programs"?
When a program is installed, the default installation location is "C:\Program Files\ (Program Name)". Where 'C' is the operating system drive. So, you can check the following site for Mozilla Firefox: "C:\Program Files\Mozilla Firefox\". When you find the executable file, you can "PIN to Start Menu". To do this, see the following steps:
(a) go to "C:\Program Files\Mozilla Firefox\" (where 'C' is the drive of the operating system).
(b) with the right button on the file used to set Mozilla Firefox and click "display in the Start Menu.
(c) click the Start button and you will see "Mozilla Firefox" listed.
Also, see the steps in the section "to pin the icon for a program to the start menu" for more information.
Hope the helps of information. Let us know if the problem persists, we will be happy to help you.

Where is Snipping Tool? If deleted accidentally, how can I get a copy for Windows Vista?
Hello Bob w. NY
Click on the Start button and type capture in the search box menu star. The cutting tool application should appear at the top of the search results.
As the cutting tool is an integral part of Windows, you might have to reinstall windows to return to the tool. Assuming, of course, you had accidentally deleted.
