Insert pk locks

Hii
When I issue an update, itl entry is opened for this row.
next transaction see that itl is open for this row and goes to rollback segments to see if it is committed
or not, if it is not committed, it will hang.
Regarding the insert statement to primay key column.
If a user insert a value to primary column and not commit, whenever another user tries to
insert the same value to that column it will hang.
How is the process in this scenerio??

If a user insert a value to primary column and not commit, whenever another user tries toinsert the same value to that column it will hang.>
As its a primary key you simply can't insert the same value again.

Inserts and locking

We have like 10 sessions trying to insert into a same table and we are experiencing heavy enq:TX waits (enq: TX - row lock contention). What I don't understand is why does the INSERTS have to wait for TX locks.
Can some one please clarify or provide some pointers on this.

Usually there are 2 senarios, insert could block others,
1. Waits for TX in mode 4 can also occur if a session is waiting due to potential duplicates in UNIQUE index. If two sessions try to insert the same key value thesecond session has to wait to see if an ORA-0001 should be raised or not.
2. Waits for TX in mode 4 is also possible if the session is waiting due to shared bitmap index fragment. Bitmap indexes index key values and a range of ROWIDs. Each entry in bitmap index can cover many rows in the actual table. If two sessions want to update rows covered by the same bitmap index fragment, then the second session waits for the first transaction to either COMMIT or ROLLBACK by waiting for the TX lock in mode 4

IPhone 4s which was bought sim-free locked to Virgin when Virgin sim was inserted. What can I do to unlock so O2 sim can be used?

The iPhone 4s was purchased unlocked. When a Virgin sim was inserted, it locked to Virgin. Need to put an O2 sim in. Would it be Virgin to unlock it or can Apple supply an unlocking code?

Only Virgin can unlock it. You'll need to contact them. The unlock process is summarized as follows:
You request an unlock
Your carrier enters the request into their system
time passes...and passes...and passes
Eventually someone at the carrier approves the request
The approved request is sent to Apple
It goes into a queue at Apple
Eventually (usually 1-2 days) Apple updates their activation database to show the phone as unlocked
You then connect the phone to iTunes on your computer and click the "Restore iPhone" button in iTunes
If the request has been processed, when the Restore is complete you will get a message "Congratulations. Your iPhone is unlocked"
You can then restore your backup.

E45-4200/Locking Cable

I cannot locate the hole to insert a locking cable into my laptop. I went to Best Buy and the guys looked at all the Toshiba Ultrabooks.....no one can find the hole to insert the locking cable. I'm traveling next week and want to secure my laptop.
Thank you in advance.
Solved!
Go to Solution.

After an exhaustive search, I found many ultrabooks do not have a Kensington slot (aka security slot) for a typical laptop lock. I think I am going to have to invest in one of the locks as shown below:

Record locking

How does Oracle 8i handle record locking?
Is this handled completely in the background by oracle or are there explicit record locks that can be set.
I understand that an update or insert will lock the current record and the commit and rollback will release the lock.
I have a problem where some developers are using an odbc connection to access an oracle database while a java servlet app is accessing the same database using jdbc. At times the changes made through the servlet app are rolled back or are not processed and the changes made by the odbc connection are kept.
I am confused as to how this could happen.
any suggestions?

I have a simmilar problem, where my program aborts too often with a record Lock.
Everytime I do an update/delete I do it using the SELECT .... FOR UPDATE NOWAIT. In order to reduce the number of aborts due to record locks I'd like to try your suggestion of catching the ROW_LOCKED error, sleep(dbms_lock.sleep in PL/SQL), and retry getting the lock a certain amount of times prior to erroring out. Can You give me more details of how to do this.
In paticular how do you use dbms_lock.sleep function/package? where can I find this package? Can you share any code examples where you have used this package.
I greatly appreciate all teh help/suggestions you can provide to me.
Thanks.

Too many sessions inserting in table

Hi All
I am new to batch programs processing .Please help me on this.
I have an application in which more than 1 session
will try to insert millions of recrds in the same table.
I need to know what care should I take for this.
Will tables be locked or I do not need to wory about this
Further in the program , one application may delete certain lacs of records while
other session might still be inserting into it
WHat do I do in this case.
Also if one session is trying to update while other session is inserting/deleting records
then what care do I take
Thanks
Ashwin N.

It is a very bad idea to have more than one session attempt to insert millions of rows (if that is a literal statement of requirement). In you have paid for it use the Parallel Server option, but always try to have only a single batch process running unless it is absoultely unavoidable. Otherwise you are increasing the risk of latch contention both for the table itself and also rollback segemnts.
Other things to check (these are database type things):
- have big rollback segment assigned to batch session;
- consider committing every 1000 records to cut down on rollback usage;
- if you're really going to have several sessions doing monster inserts like this give your table lots of freelist groups;
- make sure the table and its indexes have enough empty space by pre-assigning extents
- make sure that the tablespaces are big enough in case additional extents are required
As for row contention: rows you insert cannot locked by someone else nor are they affected by someone else inserting, updating or deleting other rows (although you might suffer from block header contention) unless that other session has issued a LOCK TABLE statement. Only once you have committed your insert will other sessions be able to see, update and delete your new rows (because Oracle doesn't support DIRTY_READ :-) )
One way of reading your question is that you think someone may be trying to delete the records you're inserting. I hope that's not the case but if it is someone ought to have a look at the business model.

How to check if row to be inserted will cause circular circular loop?

Hi-
I'm using connect by clause to do some processing and to check that the data is not causing circular loops (with SQLCODE = -1436).
Customers can add data via API, and this data, after inserted, can cause the problem explained above (loop). Therefore I need to find a way to check that these new values don't collide with the existing data in the table.
One way that currently works is to insert the data, use my pl/sql function to check that there's no loops; if there's a loop, i catch the exception, delete the rows I just inserted, and throw back the error to the user.
I find it very ugly and unneficient, but I can't find the way to use CONNECT BY with data that is not present in the table. example:
table my_table contains
parent_id | child_id
111 | 777
777 | 333
and now customer wants to insert:
parent_id | child_id
777 | 111
Also, if customer wants to insert
333 | 111
if I insert the row and run my script, it will work OK, but only if I insert the row. Is there any way to validate this without inserting/removing the row ?
the script I'm using is similar to the one posted here:
problems using CONNECT BY
thanks

This approach may fail to detect loops introduced by concurrent transactions if one of the transaction uses a serializable isolation level.
For example, assume there are two sessions (A and B), the table and trigger have been created, and the table is empty. Consider the following scenario.
First, session A starts a transaction with serializable isolation level:
A> SET TRANSACTION ISOLATION LEVEL SERIALIZABLE;
Transaction set.Next, session B inserts a row and commits:
B> INSERT INTO my_table (parent_id, child_id) VALUES (111, 777);
1 row created.
B> COMMIT;
Commit complete.Now, session A successfully inserts a conflicting row and commits:
A> INSERT INTO my_table (parent_id, child_id) VALUES (777, 111);
1 row created.
A> COMMIT;
Commit complete.
A> SELECT * FROM MY_TABLE;
PARENT_ID CHILD_ID
      111       777
      777       111Session A "sees" the table "as of" a point in time before session B inserted. Also, once session B commits, the lock it acquired is released.
An alternative approach that would prevent this could use SELECT...FOR UPDATE and a "table of locks" like this:
SQL> DROP TABLE MY_TABLE;
Table dropped.
SQL> CREATE TABLE MY_TABLE
2 (
3      PARENT_ID NUMBER,
4      CHILD_ID NUMBER
5 );
Table created.
SQL> CREATE TABLE LOCKS
2 (
3      LOCK_ID INTEGER PRIMARY KEY
4 );
Table created.
SQL> INSERT INTO LOCKS(LOCK_ID) VALUES(123);
1 row created.
SQL> COMMIT;
Commit complete.
SQL> CREATE OR REPLACE TRIGGER MY_TABLE_AI
2      AFTER INSERT ON my_table
3 DECLARE
4      v_count NUMBER;
5      v_lock_id INTEGER;
6 BEGIN
7      SELECT
8          LOCK_ID
9      INTO
10          v_lock_id
11      FROM
12          LOCKS
13      WHERE
14          LOCKS.LOCK_ID = 123
15      FOR UPDATE;
16
17      SELECT
18          COUNT (*)
19      INTO
20          v_count
21      FROM
22          MY_TABLE
23      CONNECT BY
24          PRIOR PARENT_ID = CHILD_ID;
25
26 END MY_TABLE_AI;
27 /
Trigger created.Now the scenario plays out like this.
First, session A starts a transaction with serializable isolation level:
A> SET TRANSACTION ISOLATION LEVEL SERIALIZABLE;
Transaction set.Next, session B inserts a row and commits:
B> INSERT INTO my_table (parent_id, child_id) VALUES (111, 777);
1 row created.
B> COMMIT;
Commit complete.Now, when session A tries to insert a conflicting row:
A> INSERT INTO my_table (parent_id, child_id) VALUES (777, 111);
INSERT INTO my_table (parent_id, child_id) VALUES (777, 111)
ERROR at line 1:
ORA-08177: can't serialize access for this transaction
ORA-06512: at "TEST.MY_TABLE_AI", line 5
ORA-04088: error during execution of trigger 'TEST.MY_TABLE_AI'To show that this still handles other cases:
1. Conflicting inserts in the same transaction:
SQL> TRUNCATE TABLE MY_TABLE;
Table truncated.
SQL> INSERT INTO my_table (parent_id, child_id) VALUES (111, 777);
1 row created.

ORA-06512: at "TEST.MY_TABLE_AI", line 15

1 row created.

a) First, empty out the table and start a read-committed transaction in one session (A):
A> TRUNCATE TABLE MY_TABLE;
Table truncated.
A> SET TRANSACTION ISOLATION LEVEL READ COMMITTED;
Transaction set.b) Now, start a read-committed transaction in another session (B) and insert a row:

Does the MacBook Air have a slot for a lock?

My current MacBook has a slot in which I can insert a lock to protect the computer in a public location (a library, for example).
Does the MacBook Air have the same slot?
Thanks.

Unfortunately the MBA is too thin for the Kensington lock. I've seen a couple solutions but they aren't inexpensive. I've seen this one and some of these. I recommend Prey for after the fact.

You're doing exactly what the error says, that is committing with an open LOB. Look at the following piece of code: you write in the LOB, you flush it and then commit. There is no closing of the LOB stream before committing.
Try putting the tempBlobOStream.close() instruction before the commit.
// Write the data into the temporary CLOB from the
he byte array
          tempBlobOStream.write(ba);
          // Flush and close the stream
          tempBlobOStream.flush();
nn.commit();
          //Close everything
tempBlobOStream.close();

Can_i_stop_certain_status_bar_messages?

hi all,
can somebody help / guide me about form's status bar? i have 2 problems with default status bar...
1. in some of my modules, when ever i update something and then save it, status bar issues the message "frm-40405 No changes to apply" and then save the changes too.
2. mostly it happens that a message that already persist on the status bar, when an event leads to re issue that message, the message is poped up like an alert. i dont like this since i have assigned my own color schemes to every thing, (different canvases, pop up menue, alert etc) so i dont like that green message issued like an alert...
is there any way so that i can stop certain messages from being even visible ?
and is there any way to stop the status bar messages to apear like alerts do... ?
what could be the reason that in some of my modules frm-40405 thing apears before the updates are saved...?
i dont wana make another status bar, nor i wana change any functionality of default status bar. i just need a mechanism if any, like we can over ride the default menu-items functionality...
please help this...
regards...

thanx for attention...
actually there are a number of datablocks shown on different canvases.
in 1st canvas i have a non database data block containing a search mechanism (comprising radio groups (search by donor_registration_no, donor_name, donor_nic_no etc) and a text item associated with it).
there is a database block DONOR_INFO subsequent to key_next_item of the previous block, showing a list of relevant search...
there is yet again another non database block containg buttons (donor_profile in detail and donation record).
when either of these buttons is pressed a new canvas is shown below containing relevant data in full detail.
this module is designed for searching purpose only. insertion is locked in all the blocks, updation in DONOR_INFO block is also locked since it is aimed to show only a list of relevant search. details are shown in later data blocks
the problem with this module is that, when ever i update any field in the DONOR_PROFILE or DONATION_RECORDS (data blocks) my form prompts the message "frm- 40405 No changes to apply". PLUS none of any other messages except this 40405 apears on the status bar on any event.
i have a similar PATIENT_SEARCHING_MODULE. that works all fine but this DONOR_SEARCHING_MODULE is not so
i tried ur advises: i put a form level on-commit FORM_DDL ('COMMIT');
then i put in when-new-form_instance :SYSTEM.MESSAGE_LEVEL:=25;
then i tried both but none of the try was fruitfull
if u got any other advice please help me with that...
regards...

Need to salvage HDD out of T61 crash

My T61 crashed a while back and I would like to recover the files from the hard drive. The T61 used a BIOS protection to prevent unauthorized HDD access. I have my password, but no way to use it. I can attach it to another computer via USB, the drive comes up as Unallocated. Suppose I need it to ask for the password. Not sure how to do that. I have an older T60, but have been hesitant to plug this drive into it as the primary drive as the components are a little different and it might not react well. Certainly not worth damaging a working computer.
What is the best way to recover these files?
Thanks!
Solved!
Go to Solution.

Welcome to the forum!
You won't damage the T60 by inserting the locked hard drive in it, and the hardware should be close enough for you to be able to clear the password in BIOS, and then recover the files.
Good luck.
Cheers,
George

Dreamweaver template declaration affects Google Map loading

My Dreamweaver Template declaration statement

is preventing a Google Map from loading. It works fine in IE and Firefox, but not in Safari and Chrome. The weird thing is, if I move it above the following declaration is works fine.
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" />
Dreamweaver inserts and locks this code so the only way I get it to work is to either detach it from the template completely or edit the code in a text editor before upload. I need a different fix. I'm hoping that there is actually other code in my page that is leading to the declaration problem although it seems unlikly.
For reference here is the html that calls the map
<a href="javascript:;" class="content" title="Location Map" onclick="mopen('map1');loadScript();return false">Location Map</a></p>
                  <div id="map1" style="visibility:hidden;"> <span class="content"><a href="javascript:;" class="closemap" onclick="mclose('map1')" title="Close Map">Close</a> </span>
                    <div id="googlemap1"> </div>
                  </div>
For the code or to see for yourself go to http://www.outbackadventures.com/trips_classes/kayaking/kayak_classes/intro_paddling/index 2_3.html
Any help would be much appreciated. Thanks.

The problem has been solved. It seems that Google Chrome and Safari do not entirely ignore comment tags such as Dreamweaver's template declaration.
In my "lazy load" Google Map code taken from a Google employee suggestion
http://groups.google.com/group/Google-Maps-API/msg/4e2acbe1ca7f0324
Example at http://imagine-it.org/google/gmaps-samples/dynamicloading.html
there is this line of code
document.documentElement.firstChild.appendChild(script);
As I understand it Chrome and Safari may read the Dreamweaver template comment

as the first.Child and therefore results in invalid html causing an error and no loading of the script.
This was solved by the help of folks at this post:
http://groups.google.com/group/google-maps-api/browse_thread/thread/101bc4c59d098367/0decf 0c096119f82#0decf0c096119f82
Essentially the code above needs to be modified so that it reads from the head section rather than from above it. To fix this, replace the above code with either one of the following lines:
document.getElementsByTagName(\"head\")[0].appendChild(script);
document.documentElement.getElementsByTagName(\"head\")[0].appendChild(script);

Need a help to Modify Trigger for Deadlocks issue

Is there anyway I can resolve the deadlock after modify the following trigger. Any best idea to modify the trigger?
This is the query is in the Trigger..
USE [XePro]
GO
/****** Object: Trigger [dbo].[t_SOCOMMENT]    Script Date: 01/12/2015 10:08:11 ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
-- =============================================
-- Author:        <Author,,Name>
-- Create date: <Create Date,,>
-- Description:   <Description,,>
-- =============================================
ALTER TRIGGER [dbo].[t_SOCOMMENT]
   ON [dbo].[tblICWMST]
   AFTER INSERT,UPDATE
AS
BEGIN
      UPDATE tblICWMST
      SET COMMENT = ISNULL(S.CUSTNO,'
') + ' ' + ISNULL(S.BRANDING,'
') + ' ' + ISNULL(CAST(S.TRAILCMNT as VARCHAR(MAX)),'
      FROM tblSOMAST S
      INNER JOIN tblICWMST W ON REPLACE(S.SONO, '
','') = REPLACE(REPLACE(W.WONO,'
',''), 'O','')
END
After insert, It's update whole table again and it's locked another process. I'm describing details for the column.
Table:- tblICWMST columns data types
CustNO Cahr(6)
Table:- tblSOMAST columns data types
CustNO Cahr(6)
Branding Varchar(50)
TRAILCMNT Text... Giving you data types just as if I missed anything.

Hi Danny,
I am not able to reproduce any lock with your trigger. I tried the below but after inserting no lock appeared.
CREATE TABLE tblICWMST(CustNO CHAR(6),Wono VARCHAR(99),Comment VARCHAR(99)) ;
CREATE TABLE tblSOMAST(CustNO CHAR(6),Sono VARCHAR(99),Branding VARCHAR(50),TRAILCMNT TEXT);
GO
CREATE TRIGGER [dbo].[t_SOCOMMENT]
ON [dbo].[tblICWMST]
AFTER INSERT,UPDATE
AS
BEGIN
UPDATE tblICWMST
SET COMMENT = ISNULL(S.CUSTNO,' ') + ' ' + ISNULL(S.BRANDING,' ') + ' ' + ISNULL(CAST(S.TRAILCMNT as VARCHAR(MAX)),' ')
FROM tblSOMAST S
INNER JOIN tblICWMST W ON REPLACE(S.SONO, ' ','') = REPLACE(REPLACE(W.WONO,' ',''), 'O','')
END
GO
INSERT INTO tblSOMAST(CustNO,Sono,Branding,TRAILCMNT) SELECT 'A','B','C','D'
INSERT INTO tblICWMST(CustNO,Wono) SELECT 'A','B'
DROP TABLE tblICWMST,tblSOMAST;
Regarding the code in your trigger, what does the trigger do is to update the column
COMMENT of the whole table after any insert or update. For this kind of requirement, a trigger is not the best option. The trigger runs every time when any insert or update happens on your table in your case. It is overhead on system and make
your system run slower.
Why not just wrap the code into a stored procedure and schedule it to run at a certain interval based on your business requirement?
If you have any question, feel free to let me know.

Timesheet could not add task from existing project task assignment

HI there,
I tried to add a task in Timesheet (PWA2013) from an existing assignment. However, there is no task listed under the project when I open the dialog "Add an existing task". It only shows me the project name, I click it, nothing under the project.
Due to this issue, I could not add any existing task into the timesheet.Please look at the screenshot. The "test project" is the project name, while no any task under this project.
Any help is appreciated!
Cindy

Hi Cindy,
Indeed if you cannot access the server setting from the quick launch menu in the left part of PWA, you have to request administrator rights to your admin.
I would add an important comment : in PWA2013, the "close to update" PWA2010 feature no longer exists and has been replace by the "lock" feature, which works basically the same.
To unlock tasks in PWA2013,
go to server setting, manage views,
choose a project view,
insert the "lock" column,
go to the project center,
check out your project schedule,
select the view you just modified,
change the value in the lock field for the given task,
publish the project
Read this post here: http://social.technet.microsoft.com/Forums/projectserver/en-US/28d4914d-5a80-4638-8153-94155a7d43fe/locked-feature-not-working-in-pwa-2013?forum=projectserver2010general
And this article: http://epmsource.com/2012/10/31/where-has-close-tasks-to-update-gone-in-project-server-2013/
Then it should be ok.
Hope this helps.
