Not releasing locked record
When connected to oracle server and modifying some record. The
client is switched off without disconnection. Once connected it
is not allowing me to update the same record saying 'CAN NOT
RESERVE RECORD for UPDATION ?'
Resources are released after a long time
So what is the solution. Which parameter needs seeting
Ajay :
Do you know how I can read data from a Text file into a Parameter Table in eCATT ?
I created the file by downloading the Variant from the Test Data container and updated it using XLS.
I also have named my parameter reference with my structure and added '[]' to it at the end.
I haven't had any success reading the entries into the parameter table.
Thanks
Naresh.

i want to know how can i release lock record? is there any setting in application server to do this?
thanks a lotHi
Please give some more information as your question does not seem to be complete.
Are you talking about Operating system lock or database lock .
Please provide the correct release you are currently using .

Oracle select for update: not releasing lock
My JDBC code uses "select for update" to modify record in Oracle database. I tried to simulate network connection down situation.
After my JDBC code locked on a record using "select for update", I unplugged the network cable. I then tried to run the same code on another computer, but it could not accquire the lock, because the previous lock was not released. I tried sqlplus to lock the record, but failed also. The lock has been there for at least an hour now. I guess it may finally be released, but is there a way for oracle to release the lock as soon as the connection is down? Not know if it is a JDBC setting or oracle setting.Dear Friend,
What you are trying to do is not correct way of checking the concurrency and transaction.
The reason is as listed below.
01.Always remember http is a stateless protocol and removing the connection or just closing the browser will never be informed to the database or to the application server thus the transaction monitor (TM)or processor will never release the lock as it will deem that the actor is manipulating the data.
02.As per locking goes every database is having a �TM� and the default isolation level setting is different like oracle uses serializable DB2udb 7.0 or db2/As400 uses repeatable read. You can change this setting by editing the default setting in the database but be very sure before touching it.
03. You can also transpose this with your Application server setting for that piece of code or Globally but again be very sure about it as it will change the entire gamete.
04. For releasing lock you have to manually do it or you can change the settings of App server or the Database to release the connection after some wait time.

Custom Infotype not displaying locked records in the list screen (3000)
I have a custom infotype (9xxx) that will not display the locked records (locked indicator (sprps) is set to X) in the list screen (3000) in PA20 and PA30.
Any ideas on what may be causing the records to not display in the list screen?
Thanks,
TedHi,
for creating both employee and appliciant infotype you must check 'Both' in PM01 IT tab.

Runtime.exec not releasing lock on files
Hi,
I am using Runtime.exec to launch an external application, a batch file that runs a java program and generates a pdf file on disk. The Runtime.exec is called from inside the callback function of a toolbar button in my UI. Once, the runtime.exec returns, I popup a alert saying "pdf generated successfully". However, when I try to open the pdf that has been generated, I get a message saying the "program is in use by another program" or some such message. Only when I quit my GUI application, Iam able to open the pdf file using acrobat reader.
Can someone tell me how to solve this problem. I have tried doing proc.waitFor() etc.
Cheers,
vidyutYou can try some of sysinternals tools to look through file sharing information and decide what process is locked file.
PS Try to ensure that you start java in same process as batch file executes, overthise you just can't ensure it terminates on time. -
Hi,
I am unable to delete certain files as JDeveloper does not release locks on them. One use case is when I run a build file to create a jar, war or ear file. After executing the builld, I open the file (this is when JDeveloper locks these files, I think) to check the structure and contents of the generated file. Trying to run the build again fails because, JDeveloper does not release the locks on existing file that was generated during the previous build. I have to restart JDeveloper to delete the file.
ThanksIn the meantime if you are working on the XP platform (I am guessing) then you might want to venture a look at this little program called Unlocker that is a free little utility that shows what process is grabbing the file and preventing deletion or modification and then presents to you suitable options of what to do in that situation. I have used it countless times and it works like a charm.

Reading Locked records from HR table using LDB PNP
Hi,
I am trying to read the table pa0168 using LDB PNP.
But the problem is that get pernr staement does not retrieve locked records i.e where PA0168-sprps eq "X'.
Can anybody help me with this.
I have to use LDB so i don't want a solution of writing a select * for the pa0168 table.
hence i have to use get pernr statement but it should also retrieve locked records.
how can i achieve that.? please help
Thanks

I am using advanced version of jdk. i i have used many other jar files like mysqlconnector, logging, commonhttpclient, etc.... the only problem is with mail.jar. that locks are released when its use completed, but the lock holds until tomcat shutdown in mail.jar.
what may be the reason?

BPEL Toplink Adapter not releasing table lock
We have a bpel process that attempts to do a merge on an Oracle table through the database adapter. If the merge operation is unsuccessful for any reason the process retries for a set number of times. We have found that a lock is generated on the tables in question and not released the first time. When the process retries it then hangs as it is waiting for the locks to be released.
We are using version 10.1.2.0.2
Thanks,
AshleyHi Ashley,
I don't believe this is related to cache settings.
Lets say a merge writes several rows and then fails updating the last row, at this point it has locks on the first n - 1 rows. The merge never acquires read locks.
Because the merge failed though, the transaction is rolled back, locks always get released on a roll back.
I confirmed with Glenn that when the bpel engine catches an exception, that transaction is ended (releasing all locks either way), and the next retry occurs in a new transaction.
Some guesses I have:
-in 10.1.2.0.2 turn on usesBatchWriting="true", then all the writes will happen in one statement.
-whenever a bpel process waits between steps, if the wait time is very small the instance may be kept in memory. This could mean that the next retry occurs in the same transaction as the first, so maybe you could try increasing the retry interval?
-investigate why merge is failing at all, maybe it failed in the first place because another process had a lock on the rows.
Thanks

Error: Records Could Not Be Locked
Hi All,
Users are getting the below error in the Shipping Transaction Form
ERROR
Error: This action cannot be performed on all selected records
Error: The action can not be performed because the selected records could not be locked.
I found a metalink note almost equal to this error
but in that to do the workaround where can i find the SQL scripts
a) Script to find the trailing spaces for columns in wsh_delivery_details - lock_col.sql
b) Script to find the trailing spaces for columns in wsh_new_deliveries - lock_delivery.sql
Thanks
VinayVarmaHi,
Log a SR, Oracle support should provide you with those scripts.
Also, please see if these bugs help.

How to lock records in 8.1.7?
Hi,
How can I lock records in 8.1.7 so that only one user can select/update these records at one time? If possible, can it return an error mesg if one user try to select/update records locked by others?
Thanks a lot.
DavidOracle automatically locks a row just before updating or deleting.
You can lock rows explicitly before doing an update etc by selecting it for update:
select * from emp where empno=21 for update;
update emp
set sal=sal*1.1
where empno=21;
commit;
The lock will be released on the commit (or rollback).
Please note that in Oracle, writers never block readers and readers never block writers. Which means, that although you have locked a row (or group of rows) for update, other users will still be able to select against those rows (in the pre-changed or consistant state). -
URGENT : Releasing locks aquired after the session ubruptly terminated
Hi everybody,
When a record is edited the record gets locked.
If the session is ubruptly terminated (PC switched off, Network down or something like that) before the edited record is commited or rolled back and if the same record is accessed after loging on once agian "Cannot reserve record " message is displayed.
When will such locks get released?
Is there any way to make the record editable (releasing locks programatically)?
Thanks
BrijeshThe old session should clean up given time - How, depends of course if this is a Client Server Form or a Web Deployed Form.
If it is a web deployed form then the FORMS60_TIMEOUT (or FORMS90_TIMEOUT) will be used to determine how long to wait before cleaning up the process and releasing the locks.
If this is client server then it's a database configuration thing.
There is no way to manually release the locks of an orphaned session in code. The DBMS_LOCK package does have a way of releasing a lock, but I think this is only locks that have been taken out by dbms_lock itself, not a "normal" lock. -
Is it possible to keep on locking tables after COMMIT is
executed?
I am now writing a batch program to TRUNCATE and INSERT records
into a working table, which is locked exclusively at the
beginning. A COMMIT is executed after a fixed number of records
is inserted (and the last INSERT, of course). However, I
remember COMMIT will also release lock on the working table.
The problem is that I wish to keep the exclusive lock on the
working table until the end of the program. This is because I
need to further process the working table's contents, which are
supposed to be "freezed" until the end.
How can I do that?you can try using the dbms_lock package to create your own lock,
this way you can choose to not automatically release the lock
when you commit.
I never used it, but in the oracle documentation you should find
more information about how to use this package. -
Lock records when in Update Mode / problem with 2 users on 1 document
Hi,
when user A updates e.g. a purchase order and user B goes into this purchase order and updates e.g. the remark before user A, then user A cannot save his changes. Imagine user A has put in several new lines and has made several price adjustments, his work will be gone.
In most cases this should not happen very often, but it could. Since B1 recognizes when another user has updated the document before, it should be possible to solve this situation more convenient (either by lock, saving to a new document, comparing to the old version, etc).
Thank you
SebastianHi Sebastian,
Your request is understandable. It may not have big problem to change current process by coding. However to lock records whenever in update mode, that could create too many locks. It is basically not good for performance. The trade off may be allowing save as function. However, this may not be a desirable solution for most end users.
Thanks,
Gordon
