Updating the same row in different sessions

Hi,
I've one table application(appl_no varchar2(10), locked_user varchar2(8)) which is used to track which user is logged in at present.
As soon as any user is logged in to the system via front end, the user ID is populated to locked_user column so that no other user cannot access the same appl_no. As soon as the user exits from the front end, the locked_user is updated to null.
We've experiencing a strange behaviour in our system where one user exits from front end and at the same time(previous transaction is not committed) the same user ID opens the same application in another session, but the session session doesn't gets hanged(waiting for the lock to be released) and tries to update the same row which was locked by first user's session. We come to know this thing when the trigger on the table gets fired in both sessoins.
Now I want to know if there is any locking machanism in Oracle where the same row can be updated in 2 different sessons one after another when the first session has not committed its changes?
Thanks
Deepak

And obviously no two sessions can update the same record at the same time
Yes I know that and I tried the same thing by myself on 2 different sql sessions which is not happening, but this is happening when the same is being done from front end(Power Builder based application).
Just wanted to check is there any possibility where this can be possible?
Thanks
Deepak

Insert a field and update the same row.

Hi,
I am inserting a value in a row.
And later within a cursor loop I am trying to update the same row. But it is not working....
CREATE OR REPLACE procedure Del_Note_stage
Is
v_delNote Delivery_Note.Delivery_Note_id%type;
Cursor C1 is Select Heading_Name,File_Data from Sqlload_Stage;
Begin
dbms_output.put_line('i am here a ');
Select Delivery_Note_Id_Seq.nextval into v_delNote from dual;
Insert into DELIVERY_NOTE_STAGING(Delivery_Note_ID,LUT,LUB,PROCESSED) Values(v_delNote,sysdate,'Config','N');
commit;
dbms_output.put_line('i am here b'||v_delNote);
For sqlload_rec in C1
   Loop
    dbms_output.put_line(sqlload_rec.Heading_Name);
    dbms_output.put_line('Del Note Id is :'||v_delNote);
    update DELIVERY_NOTE_STAGING set deployed_by='TOM' where delivery_note_id=v_delNote;
End loop;
End;

But it is not working....Why not?
Please read: http://tkyte.blogspot.com/2005/06/how-to-ask-questions.html
Why are you updating after inserting?
Just add deployed_by to the insert statement, or use a default value for that column.
Also you don't need to select your Delivery_Note_Id_Seq.nextval from dual, just use it in your insert statement.
Something like:
Insert into DELIVERY_NOTE_STAGING(Delivery_Note_ID,LUT,LUB,PROCESSED,deployed_by )
Values( Delivery_Note_Id_Seq.nextval,sysdate,'Config','N', 'TOM' /*or USER*/);

Using a custom itemrenderer in datagrid to update value in the same row but different column/cell

Here's what I have so far. I have one datagrid (dg1) with enable drag and another datagrid (dg2) with dropenabled. Column3 (col3) of dg2 also has a custom intemrenderer that's just a hslider.
When an item from dg1 is dropped on dg2, a custom popup appears that asks you to use the slider in the popup to set a stress level. Click ok and dg2 is populated with dg1's item as well as the value you selected from the popup window. I was also setting a sliderTemp variable that was bound to the itemrender slider to set it but that's obviously causing issues as well where all the itemrenderer sliders will change to the latest value and I don't want that.
What is needed from this setup is when you click ok from the popup window, the value you choose from the slider goes into dg2 (that's working) AND the intemrenderer slider needs to be set to that value as well. Then, if you used the intemrenderer slider you can change the numeric value in the adjacent column (col2).   I just dont know how to hook up the itemrenderer slider to correspond with that numeric value (thatds be in col2 on that row);

Two Infopath forms to submit or update the same sharepoint list

Hi, I'm building a request SharePoint site so users can submit a request from a simplified InfoPath form (with only 5 out of 10 fields), but support personnel can open the form and then see all 10 fields. For the list view, I know I can create custom
views when user's see the list. But when they open an item, I only want them to see the fields they entered and not the other fields the support personnel can see. So I guess my question is: can I create two InfoPath forms to update one list or
can I create an InfoPath form that has two views so one view suppresses fields and the other does not (based on permissions perhaps).

Hi Darby,
I would suggest creating two views, instead of two forms. Views can be shown/hidden based on the logged in users, takes few rules to configure based on the logged in users. you can also explore web service to get the users from groups to show/hide based
on the user group, little overhead but give more control due to the fact of one single form.
Two forms will be bit complex, if you want to update the same rows of information.
here are some references -

ADF 11g Partial Triggers Row Column Update By Column in the Same Row

Hi.
I have a situation whereby I have a checkbox in a table row, which has an eventchangelistener, which upon activation, trys to update another column in the same row. I can not get this to work through partial triggers, even though I have set up my ids up correctly. The row though can be updated by a command button outside of the table using the same coding techniques, but I need it updated via the checkbox.
Is there a limitation in updating a column within a row, from another row column's event change listener.
Thanks.

Updating the other rows from the checkbox works fine for me. Here is what I did.
I DnD Emp table with a new column that says if the emp is new hire. If the checkbox is checked, I set Firstname and Lastname for that row as NewHire. I have partial triggers on Firstname and Lastname columns to update whenever checkbox is checked/unchecked and autosubmit on checkbox to true. Hope this helps.
Try adding column selection property to single and see if it helps.

Multiple users updates the same data - RowInconsistentException

Hi,
I'm using JDeveloper 11.1.2.1
Locking mode: optimistic
Scenario:
- Have 2 users (user 1 & user 2) running application x
- Both users updates the same record
- user 1 hits save first (and hence no error)
- user 2 hits save after user 1, and gets RowInconsistentException
I have managed to trap the exception in the EntityImpl class:
public void lock() {
try {
super.lock();
catch (RowInconsistentException ex) {
this.refresh(REFRESH_UNDO_CHANGES);
super.lock();
But what this does is that it just refreshed the entities and removed user 2's work without notification, which isn't acceptable.
Instead of this, is it possible to display an error message in user 2's UI (instead of the stack error) , refresh the entities, but keep user's 2 work, and possibly recommit?
Thank You
Regards,
Andi

Andi,
, is it possible to display an error message in user 2's UI (instead of the stack error)You can customise the error handling, yes, to display a different message if you like (check out the Fusion Developer's Guide to find out how)
refresh the entities, but keep user's 2 workNot sure what you mean there
By default (at least it used to be this way, haven't checked recently), if you commit again after receiving the "row inconsistent" error, it will save user 2's changes (potentially overwriting user 1's changes)

How to find out, who locked the same row

Dears,
I have a problem,
sometimes our user complain that, when he tyring to make a transaction to a specific customer's Account
its says 'Some other user access the same account, keep trying...' (like this).
and in this response I just kill that user's session. then he can make the transaction by reconnecting.
sometimes my solution(killing the session) can not slove this problem.it stayed even 5/6 hours long.
in this time,i cannot find any bloking session or such a long waiting session.
In this Scenario..
I need to find out who(SID,SERIAL#,USERNAME) locked the same ROW (not table).
There are many users who are locking different rows of the same table at the
same time. I need to find the one who locked my row.
is it possible to find out, who locked the specific customer's Account ?
I am trying to find out by the following query but failed.
SELECT s.SID, serial#, machine, osuser, terminal, b.object_name,

Just check with this query, find the lock and kill the session.
select b.session_id ,a.SERIAL#, a.username "Blocker Details"
from v$session a,dba_lock b
where b.session_id = a.sid
and b.blocking_others = 'Blocking';

Insert then update on same row in bean Transaction leads to deadlock

<b>Setup Details</b>
Hibernate version: 3.1.2
EJB version: 2.0
Name and version of the database : MS SQL Server 2000
Datasource implmentation class being used : com.sap.nwmss.jdbcx.sqlserver.SQLServerDataSource
We are using SAP NetWeaver Application Server 6.0 and Hibernate 3.1.2 in our application. We have StalessSessionBeans which use Hibernate to interact with the database. We are running into a situation where the application goes into a hang state when the following flow is bein executed:
//transaction attribute = "Required"
beanMethod() {
myObj = new MyObj();
myObj.setSomeValue();
session = SessionFactory.openSession();
//id is auto generated by database
id = session.insert(myObj);
//retrieve the recently inserted obj
myUpdatedObj = session.load(id);
//modify the myUpdatedObj
myUpdatedObj.modifySomeValue();
//update using hibernate session
session.update(myUpdatedObj);
//return from method
Here's the flow:
1) In a CMT stateless session bean, there's a method which has transaction atrribute as "Required"
2) This method creates a new object and inserts it
3) Then loads this saved object and modifies some values in it
4) Then invokes the update method on the session to update this modified object in the database.
Note: We have enabled auto flush on transaction in the hibernate configuration file.
And here's what we are observing:
- The insert obtains a lock on the row as part of the transaction
- When the update is called on the same row as part of the auto flush, the update never completes. The update statement is unable to obtain a lock on the same row.
Here is some additional info:
- We have set :
session.connection().setTransactionIsolation(Connection.TRANSACTION_READ_UNCOMMITTED);
hibernate.cfg.xml:

Any clue why the update query is having problem in completing, even though update and insert are being called from the same bean method as part of a transaction?

Is there a way to add a column after a filled DataTable from SQL with the same rows?

My problem is that not to add rows like filled by SQLDataAdapter at the same row in DataGridView. How to make that? I showed below the details with my code also a screen shot, which shows the rows differences from the origin one.
I don't want to add an expression as column behave in my sql script to get what I need with query result. I don't want to obtain that way.
using (SqlConnection c = new SqlConnection(ConnStrMSSQL))
c.Open();
// 2
// Create new DataAdapter
using (SqlDataAdapter a = new SqlDataAdapter("SELECT SIPNO, SERINO, TARIH FROM SNOHAREKETLER WHERE Cast(TARIH as DATE) BETWEEN '2015/03/20' AND '2015/03/20' AND (TEZNO = 'T23' OR TEZNO = 'T31') AND CIKTI is null", c))
// 3
// Use DataAdapter to fill DataTable
DataTable t = new DataTable();
a.Fill(t);
t.Columns.Add("MyColumn", typeof(string));
DataRow workRow;
int iGetCount = t.Rows.Count;
for (int i = 0; i <= iGetCount - 1; i++)
workRow = t.NewRow();
workRow["MyColumn"] = i;
t.Rows.Add(workRow);
dataGridView1.DataSource = t;

The extra column isn't applied to only certain rows. The columns of a table identify what data each row will contain. Hence adding a column to the table automatically adds them to the rows. What you're seeing is that all the initial rows
aren't being assigned a value so they retain their default value of null. Later you enumerate the rows of the existing table and call AddRow which adds new rows. This isn't adding columns, but rows.
To generate values for the existing rows you should ideally simply pass the data back from the database. DT computed columns can be difficult to set up as it is limited to what it can do. If you want to use a computed column on the Datatable
itself then define the column as a computed column and every row will calculate its own value.
DataTable data = GetData();
//Add elapsed time column
var col = new DataColumn("ElapsedTime", typeof(TimeSpan), "expr");
data.Columns.Add(col);
dataGridView1.DataSource = data;
The issue you will run into however is that calculating a diff on DateTime doesn't work in a computed column as the expression doesn't support the necessary functions. You can google for how people solved this if you are interested in alternatives.
Most people just tend to add the column and then hook into the various change events to update the value as needed.

Radio group in classic report based on another column on the same row.

Oracle Database 11g Enterprise Edition Release 11.2.0.1.0 - 64bit Production
Application Express 4.1.0.00.32
How can I have a radio group column based on an LOV utilizing another column on the same row of the report?
For example: what if I had a survey application and depending on the likert scale that was assigned to the question there would be different possible answer choices:
Question 1 on row 1 of the report: The class instructor was friendly?
Likert scale choice is Agreement.
Choices on Radio Group: Strongly Agree, Agree, Undecided, Strongly Disagree
Question 2 on row 2 of the report: The class offered good materials?
Likert scale choice is Quality.
Choices on Radio Group: Excellent, Below Average, Average, Above Average, Excellent
The radio group can change per row depending on the Likert scale assigned to the question which is assigned to a different column on the row.
Can LOV utilize the column? :
SELECT scale_text
FROM scale_choices
WHERE scale_category_choice_id = 2 <<= this would be the Likert scale identifier
ORDER
BY display_order

Here is the answer:
APEX_ITEM.SELECT_LIST_FROM_QUERY(
p_idx IN NUMBER,
p_value IN VARCHAR2 DEFAULT NULL,
p_query IN VARCHAR2,
p_attributes IN VARCHAR2 DEFAULT NULL,
p_show_null IN VARCHAR2 DEFAULT 'YES',
p_null_value IN VARCHAR2 DEFAULT '%NULL%',
p_null_text IN VARCHAR2 DEFAULT '%',
p_item_id IN VARCHAR2 DEFAULT NULL,
p_item_label IN VARCHAR2 DEFAULT NULL,
p_show_extra IN VARCHAR2 DEFAULT 'YES')
RETURN VARCHAR2;

1 app, 3 devices, 1 iCloud - how can I run the same game on different devices?

My wife and I share one iTunes account and one iCloud account for 2 iPhone 5's and an iPad. Our home laptop is a PC running windows 7. We are not able to both play the same game (specifically Carcassone) at the same time on different devices which is frustrating, how can I make this happen? Do I need two separate accounts? Can I have two accounts with a PC? We don't want to sacrifice the photostream to get it though.
Thank you,
Jacob

Go to iTunea>Preferences>Devices and see if there is a backupright at the time you did the update. Then try restoring from that backup. If the apps are in your iTunes library, any app data will be restored to the iPod.
When restoring from an iOS 4 (or later) backup, if the device had a passcode set, iTunes will ask if you want to set a passcode (and remind you that you had protected your device with a passcode). iTunes will not ask you to set a passcode when restoring from iOS 3.x and prior backups.
Therefore, remembe the passcode that you enter this time.
It appears that if you restore from a backup, that backup is not subseqyently overwritten by the next backup.

Multiple instances of the same bean class in session?

I�m trying to think of a way to have multiple instances of the same bean class in session scope using JSF. For example, let�s say that I have two <h:dataTable>s on the same page. They both use the backing bean called genericBean. Now, the content for genericBean will be different for each <h:dataTable>. In fact, the data source that backs genericBean is not known until runtime. It could be a database, web service, etc.
What I would like is for when JSF needs access genericBean instead of looking for the value with key �genericBean� in the session map it looks for �genericBean_[some runtime ID]�. I could specify this id in EL on a custom component, as a request parameter or whatever.
I think that I need the bean to be in session scope because the tables are complex and I want them to be editable.
I have some ideas about how I can do this but I was wondering if someone has already solved this problem or if there is a standard way to do this using tools like Shale, etc.
Thanks,
Randy

Well, I came up with an interesting solution to this so I thought that I would post it here.
I have a page that looks like this.
<html>
<head>
<title>My Page</title>
</head>
<body>
<f:view>
<f:subview id="component1">
<jsp:include page="component.jsp">
<jsp:param name="id" value="a" />
</jsp:include>
</f:subview>
<hr>
<f:subview id="component2">
<jsp:include page="component.jsp">
<jsp:param name="id" value="b" />
</jsp:include>
</f:subview>
</f:view>
</body>
</html>
And component.jsp looke like this.
<f:verbatim>
<p>
<h1>Component
</f:verbatim>
<h:outputText value=" #{param.id}" />
<f:verbatim>
</h1>
</p>
</f:verbatim>
<h:form>
<h:outputText value="#{component.id}" />
<h:outputText value="#{component.value}" />
<h:commandButton value="increment" action="#{component.increment}" />
<h:commandButton value="decrement" action="#{component.decrement}" />
<f:verbatim>
<input type="hidden" name="id"
value="</f:verbatim><h:outputText value="#{param.id}"/><f:verbatim>" />
</f:verbatim>
</h:form>
The idea is that I want component.jsp to be initialized differently based on the id param. The component managed bean is configured to be in session scope but I want the component instance for id a and id b to be different instances in session scope. Therefore, I added a custom variable resolver to handle this.
public Object resolveVariable(FacesContext context, String name) {
// This id will be different for the different subviews.
HttpServletRequest request = (HttpServletRequest) context.getExternalContext() .getRequest();
String id = request.getParameter("id");
// If there is an id in the request then check if this is a bean that can have multiple
// instances in session scope.
if ((id != null) && (id.length() > 0)) {
ExternalContext ec = context.getExternalContext();
// Build the new name for the key of this bean
String newName = name + "_" + id;
Object value = null;
// See if the bean instance already esists.
if ((null == (value = ec.getRequestMap().get(newName))) &&
(null == (value = ec.getSessionMap().get(newName))) &&
(null == (value = ec.getApplicationMap().get(newName)))) {
     // We could not find the bean instance in scope so create the bean
     // using the standard variable resolver.
value = original.resolveVariable(context, name);
// Now check if the bean implements that page component interface. If it is
// a page component then we want to rename the key to access this bean so
// that the instance is only used when the id is provided in the request.
// For example, if there are two components (a and b) we will have in session scope
// component_a and component_b. The will each point to a unique instance of the
// Component bean class.
if (value instanceof PageComponent) {
// Try to get the value again
if (null != (value = ec.getRequestMap().get(name))) {
     // Initialize the bean using the id
((PageComponent) value).initInstance(id);
ec.getRequestMap().remove(name);
ec.getRequestMap().put(newName, value);
} else if (null != (value = ec.getSessionMap().get(name))) {
((PageComponent) value).initInstance(id);
ec.getSessionMap().remove(name);
ec.getSessionMap().put(newName, value);
} else if (null != (value = ec.getApplicationMap().get(name))) {
((PageComponent) value).initInstance(id);
ec.getApplicationMap().remove(name);
ec.getApplicationMap().put(newName, value);
return value;
return original.resolveVariable(context, name);
}

How to use the same element in different photoshop files?

It occurs to me often that I use the same element in different photoshop files, a header or footer shown in the example below. So when the footer changes in one document, I need to change this footer in every other single document.
Is there a possibility to use some kind of template, one single document, that can be placed in different files , which is still editable afterwards?
Thanks in advance.
I'm using Photoshop CS6

In a single document you can have several pages and these pages may have headers and footers that share smart objects. If you replace the contents of the an embedded smart object on one page page that is shared on an other page the pages you will see both pages contents are changed. For they share the common object. It is also possibly to have independent smart object layers. It depends how you create the layers in the single document.
Example one sharing a smart object hi-light a smart object layer and use menu layer>Duplicate Layer... This will create a second smart object layer that share a common smart object. Each layer has is own associated transform. Do it again and you will have three layers the share a common smart object. So you can use each layer associated transform to position and size the layers contents. Make a picture package for example. When you hi-light any of the three smart layers and you use menu Layer>Smart Objects>Replace Contents... all three layers contents will be replace with the new smart object. Care must be taken to replace the smart object with an identical size object for only the object is replaced the three associated transform for the three layers are not replaced or changed.
Example two independent smart objects hi-light a smart object layer and use menu layer>Smart Objects>New Smart Object via Copy. This will create a second smart object layer that has it own embedded smart object copy. Do it again and you will have three all have independent embedded smart object that are identical. However they do not have to remain identical. For example if the first smart object layer was created by using ACR to open a RAW file as a smart object layer the embedded object is a copy of the raw file and its associated RAW conversion settings. Double clicking on one of the smart object layers and you will see ACR open on its embedded RAW file with the embedded RAW conversion setting. Changing these settings will update the layer smart object content with new ACR setting and pixel when you click OK in ACR. Repeat for the third and you will find you have three different raw conversions in Photoshop you can mask and blend together to bring out detail.
I think what your missing is that a smart object contains a copy of the original object. Changing the original after creating a smart object layer in document will not effect the smart object layer at all. Its independant from the original having a copy of the original. Only changes to the smart object layer and its embedded smart object effect smart object layers.

Multiple updates to same row

Hi experts,
I still cant figure out how oracle handles multiple updates to the same row. For instance I have 3 update statements:
update supplier set supp_type = 'k' where supp_code = '1';
update supplier set supp_type = 'j' where supp_code = '1';
update supplier set supp_type = 'm' where supp_code = '1';
I keep getting the final result to be supp_type = 'k' where it should actually be 'm', but when i execute the mapping it shows 3 update operations, which baffled me as to how oracle handles simultaneous updates to same row. I even tried disabling parallel dml on the table object, but am unsure whether this actually helps. I try putting a sorter operator and then a key lookup operator after the sorter operator in my mapping to compare the supp_code field in the sorter with the target table's supp_code field to retrieve the relevant row to update, but instead of 3 update operations, it now updates all supp_type in all my records to NULL. Can anyone explain to me how i should go about dealing with this?

Hi experts,
I just took a look at the code section generated for the key lookup operator named SUPPLIER_WH_SURRKEY01 and I feel something is wrong with the generated code. I have pasted the code section on the key lookup operator below.
ORDER BY
"SUPPLIER_CV"."RSID$" ASC ) *"SORTER" ON ( ( ( "SUPPLIER_WH_SURRKEY01"."EXPIRATION_DATE" = "SPIDERWEB2"."GET_EXPIRATI_0_EXPIRATI" ) ) AND ( ( "SUPPLIER_WH_SURRKEY01"."SUPPCODE" = "SORTER"."SUPP_CODE$1" ) ) )*
WHERE
( ( "SUPPLIER_WH_SURRKEY01"."SUPPKEY" IS NULL ) OR ( "SUPPLIER_WH_SURRKEY01"."SUPPKEY" = "SUPPLIER_WH_SURRKEY01"."SUPPKEY" ) );
Can anyone explain to me the codes in bold? I have no clue as to what it means? Furthermore, those bold-ed codes look similar to what I have expected to find in the where clause, except that instead of SUPPLIER_WH_SURRKEY01"."EXPIRATION_DATE" = "SPIDERWEB2"."GET_EXPIRATI_0_EXPIRATI", I expected to find
SUPPLIER_WH_SURRKEY01"."EXPIRATION_DATE" = '31-dec-4000', because my key lookup operator checks upon a constant with the value '31-dec-4000'. And the constant name is CONSTANT itself, while my mapping's name is SPIDERWEB2(not too sure why the generated code refers to my mapping name instead of my constant)
