Regarding locked(timed)

HI,
i got a query from one of my developers that while trying to connect to user they are getting error the account is locked.i checked the account_status from dba_users and it showed me loked(timed).
when does this happen.
can any one suggest me.
regards,
kishore.

It happens when you try to login with wrong password.
So maximum tries depending on values set in your user profile, your user will be locked..

Locked(Timed)

Hello.
I have just installed Oracle 10g database, and an applicative account keeps getting locked out. The note in Enterprise Manager says Locked(Timed), so I know it is a timed lockout. I have unlocked, expired password, changed password and everything I know to do, but it still keeps happening. I have not see this in previous versions of Oracle, so what did I do wrong? How can I correct the problem? Thanks!!!
There is a way to monitor and create an audit table with all logins in order to see where this problem occours?

If you enable auditing then set AUDIT SESSION
you would be able to query the DBA_AUDIT_SESSION view to identify successful and failing logins.
An account goes into "LOCKED(TIMED)" when
a. It has a profile that is configured with FAILED_LOGIN_ATTEMPTS and PASSWORD_LOCK_TIME
b. Some one or some application / client attempts the account with the wrong password
Oracle then "locks" the account after the number of consecutive failing logins exceeds FAILED_LOGIN_ATTEMPTS and the account remains locked for PASSWORD_LOCK_TIME.

Regarding locks in SAP ( concurrent access by two reports for a same table)

Hi All,
I have a problem regarding locks. I have designed a report using lock function modules to set locks and release them after the database operations and it works perfectly. There is another report which also does some DB operation on the same table but there are no table locks using enqueue function module implemented in this report and despite of lock set by first report on the table it is able to do the changes on the db table. I need to know how to overcome this problem.
Thanks for your solutions.

Sachin

lock procedure requires that all programs involved cooperate. Inconsistencies can occur if a program reads or changes data without having previously locked it. When a lock is set, the data records are only protected against changes by another program if this program also requests a lock before accessing the data.
Please check the above extract from [SAP help|http://help.sap.com/saphelp_nw04/helpdata/en/cf/21eed9446011d189700000e8322d00/frameset.htm], to maintain data consistency, it must be ensured that all the programs should lock the data before changing.

Difference between LOCKED and LOCKED(TIMED)

Hi,
Could anybody please elaborate the difference between LOCKED and LOCKED(TIMED) of a user in Oracle
I checked several explanations but did not get clear idea.
Please assist me..
thank you..

Hi,
The first one is simple locking.
But the second occurs when user has failed password attempts which was given to him/her via FAILED_LOGIN_ATTEMPTS PASSWORD parameter in his/her profile:
SELECT username, account_status FROM dba_users WHERE username= ‘USER_NAME’;
and
SELECT resource_name,resource_type,limit FROM dba_profiles WHERE profile='PROFILE from 1st query';

Regarding Locking of PL/SQl Procedure or function

Hi,
My PL/SQL code is getting locked. The flow is like this.
My PL/SQL code writes a particular data into a file which is read by a C program. Once the processing is done then the C driver writes back into anither file called response file from which my PL/SQL code reads from. What is happening is I use dbms_lock.sleep in my PL/SQL code. Now my PL/SQL code is hanging. In the sense when try to recompile my PL/SQL file, it gets timed out saying that It could not lock the object [Function Name]. How can I find out whether any other process is using my File or not. Even if it using how can I release the lock.
Thanks in avance

I think you have executed this PL/SQL code earlier and is hung. When you are trying to recompile that, it is not allowing to change the code as it is already being used and "locked".
You need to find out the session which is holding the lock on this code and kill the same.

Doubt regarding Lock

Hi,

Regarding Lock objects concept

Hi,
   I am interested in knowing what is the significance of Lock objects in SAP.
   Can we co-relate SAP lock objects with Oracle.
    Frnds, I dont need any material i hav enough but i want to know the cocept behind this.
Thanking u all.
regards,
suraj

Hi,
When you create a lock object System automatically creat two function module.
1. ENQUEUE_<Lockobject name>. to insert the object in a queue.
2. DEQUEUE_<Lockobject name>. To remove the object is being queued through above FM.
http://help.sap.com/saphelp_nw04/helpdata/en/cf/21eea5446011d189700000e8322d00/content.htm
GO TO SE11
Select the radio button "Lock object"..
Give the name starts with EZ or EY..
Example: EYTEST
Press Create button..
Give the short description..
Example: Lock object for table ZTABLE..
In the tables tab..Give the table name..
Example: ZTABLE
Save and generate..
Your lock object is now created..You can see the LOCK MODULES..
In the menu ..GOTO -> LOCK MODULES..There you can see the ENQUEUE and DEQUEUE function

Regarding lock at SAP system

hay,
our client says, suddenly today SAP 40B Prod system does not allowusers to login to system. so we had restarted the server. but we would like to know the possible reason for this occurence.
could somebody guide me what are all things i have to check and what could be reason to get lock.
I checked Systemlog but could not able tojudge particular reason for it..is there any procedure to findout.
helps could be appreciated.
ambichan.

Hola Ambi,
there could be a lot of reason,
first one, you have dialog process, if all dialog process are busy ... you will not be abble to login to SAP. (I thing this case was not in the syslog).
seconde, maybe the table USR02 had some trouble, did you check the database table USR* ?

Monitoring lock timing through CCMS

I want to setup a ccms monitor that has to notify when locks under SM12 are older than 24 hours. Can anybody have the information through which monitoring method I can configure this (solution manager 4.0 or WAS6.40)?
Thanks
Sateesh

Hallo Sateesh,
such a monitor does not exist within the SAP delivered monitor templates. You would need to create (which means you have to write a function module or report) your own data collector to get this data. The document <a href="http://service.sap.com/~sapidb/011000358700001752571999E/SUPPLIER_46A_EN_Neu.pdf">How to Write a Data Supplier for the Alert Monitor</a> describes how to do this.

Regarding Lock Object

Hi Experts,
Can you please guide me how i can find out the lock object name. If i know the table name. is there any table which stores the table name and lock object name for that table.
Or any function module to which i can pass table name in return i can get lock object name.
i have to do all this by coding.
Its very urgect.
Thanks in advance.

Hi
Lock Objects Tables is: <b>DD25L</b>
Lock objects are use in SAP to avoid the inconsistancy at the time of data is being insert/change into database.
SAP Provide three type of Lock objects.
- Read Lock(Shared Locked)
protects read access to an object. The read lock allows other transactions read access but not write access to
the locked area of the table
- Write Lock(exclusive lock)
protects write access to an object. The write lock allows other transactions neither read nor write access to
the locked area of the table.
- Enhanced write lock (exclusive lock without cumulating)
works like a write lock except that the enhanced write lock also protects from further accesses from the
same transaction.
You can create a lock on a object of SAP thorugh transaction SE11 and enter any meaningful name start with EZ Example EZTEST_LOCK.
Use: you can see in almost all transaction when you are open an object in Change mode SAP could not allow to any other user to open the same object in change mode.
Example: in HR when we are enter a personal number in master data maintainance screen SAP can't allow to any other user to use same personal number for changes.
Technicaly:
When you create a lock object System automatically creat two function module.
1. ENQUEUE_<Lockobject name>. to insert the object in a queue.
2. DEQUEUE_<Lockobject name>. To remove the object is being queued through above FM.
You have to use these function module in your program.

Questions regarding Lock Objects.

I am creating a custom table and I want to implement a unique ID for my table and I want to use the technique of auto-increment. I created a seperate table where to store the increments to be used as IDs. So basically, when a new data is going to be saved on my other table, the program will query the next "id" from the table for increments. I have to make sure that the updating and reading of the data from the table is accessed one at a time to rule out the possibility that there will be no duplicate IDs generated.
I have read about shared locks and exclusive locks which would serve as a solution for my purpose. The question is: is it possible for other users to "read" from a table if it is currently in an "exclusive lock" by another user?

No it isn't.
When you've selected your current value with SELECT FOR UPDATE (to get the exclusive lock) then every other reader will have to wait.
But is this really what you want?
Putting locks on something like an increasing number that is just used for an internal ID?
This will do nothing but turn your multiuser database application into a one-by-one slowness.
Instead, check the documentation about SEQUENCES.
These database objects were made for this. Lockfree increasing (or decreasing) numbers for unique ID columns.
Easy to use. Safe to use.
In 99.9% of all cases this is what you should use.

Lars

also there is means to restrict access to the specified tables by assigning it to a request and then having restrictions over the request. But this is done by the administrators ony.

need to make it thread safe. Also, store the handle of the session bean

By the way, session beans (handle or otherwise) are not meant to be stored

Regarding Lock

Hi
I have a select statement which is being excessed by 2 processes at the same time and is showing a dead lock error when second process executes it . Please let me know how to use parallel process in a sql my query is
select * from xyz ;
I have tried using FOR UPDATE also and it didnt work

> IMPORTANT: A select for update will never cause a dead lock.
<p>
Wrong. That should have been written like this:<br>
<h3>IMPORTANT: A select for update will never cause a dead lock!!!!</h3>
<p>
<p>
> Voilà, that is the solution.
<p>
Not really - that is the identification of the problem. The solution is to write code that groks how concurrency and locking work in Oracle. Which is why reading the Oracle® Database Application Developer's Guide - Fundamentals is mandatory for all Oracle developers.
<p>
If you write code that runs against or on an Oracle instance.. and you have not read and understood this manual.. you only have yourself to blame for all the problems and frustrations you will have using Oracle.
