  In the attached VI why looping force the type of data while the other does not?

  I'm guessing that you have created the Enum on the front panel.  If you right click and create an indicator, it corresponds to the type and be an enum.  LabVIEW represents enums as U16, but because the types are not the same (for example, your enum has 3 values, but a U16's 65 536 values), LabVIEW automatically converts value (or converts) the smallest representation (enum) in the largest value (U16).

• How do to set the policy, the user should not change/reset password twice within 24 hours

  Hello

  I have a requirement in which, the user should not change/reset password twice within 24 hours. Is there a way to achieve the IOM.

  Is there a property in IOM whereby we can set this property?

  I checked the password and all the properties of the system strategy, but he could find a?

  Could you please suggest, how to get there. all references are greatly appreciated.

  Thanks in advance

  If you set password history on don't allow orevious you can reference the table pwh.

  You can also create a UDF who inquire about the handler reset passwoed and check against it. IOM has many points of validation of your code to.

• Convert data in hierarchal of hierarchical data for the creation of the tree

  Hi guys,.
  
  I tried to figure this out for about two days together now and I'm still stuck and I see no possible solution that does not involve a new creation of the table.
  I want to create a tree to navigate through projects and tasks, I use the demo "Task Manager" app, which I customized it a bit to fit my needs.
  
  Basically, I can't create the tree because the relationship between projects and tasks is not a hierarchical relationship, it's a relationship 1: n like this:
  
  __Projects__
  ID (PK)
  PROJECT NAME
  
  
  
  ___Tasks___
  ID (PK)
  Project (done FK reference Projects.ID)
  
  
  So what I have to do is to "force" this relationship 1: n with a hierarchical relationship by creating a query (view) that links the two tables into one and have 2 columns, I can use as ID and PARENT_ID for the creation of the tree.
  
  This is the data model:
  
  
  CREATE TABLE 'EBA_TASK_PROJECTS '.
  (NUMBER OF 'ID',
  'PROJECT_NAME' VARCHAR2 (255),
  "CREATED_ON" DATE NOT NULL ACTIVATE.
  'CREATED_BY' VARCHAR2 (255) NULL NOT ACTIVATE.
  DATE OF THE "UPDATED_ON"
  "UPDATED_BY' VARCHAR2 (255),
  'FLEX_01' VARCHAR2 (4000).
  'FLEX_02' VARCHAR2 (4000).
  'FLEX_03' VARCHAR2 (4000).
  'FLEX_04' VARCHAR2 (4000).
  'FLEX_05' VARCHAR2 (4000).
  NUMBER OF "PARENT_ID"
  VARCHAR2 (1) 'IS_ACTIVE ',.
  VARCHAR2 (4000) "DESCRIPTION."
  CONSTRAINT CHECK of 'EBA_TASK_PROJECTS_ACTIVE_CC' (in is_active ('Y', 'n')) ENABLE,.
  ENABLE 'EBA_TASK_PROJECTS_PK' CONSTRAINT PRIMARY KEY ('ID')
  ) ; ALTER TABLE 'EBA_TASK_PROJECTS' ADD 'EBA_TASK_PROJECTS_FK' OF CONSTRAINT FOREIGN KEY ('PARENT_ID')
  REFERENCES 'EBA_TASK_PROJECTS' ('ID') ON DELETE CASCADE ACTIVE;
  
  
  CREATE TABLE 'EBA_TASK_TASKS '.
  (SELECT 'ID' NUMBER NOT NULL,)
  ACTIVATE THE "PROJECT" NUMBER NOT NULL,
  ACTIVATE THE "TASK_PRIORITY" VARCHAR2 (400) NOT NULL,
  ACTIVATE THE "TASK_DIFFICULTY" VARCHAR2 (400) NOT NULL,
  ACTIVATE THE "TASKNAME" VARCHAR2 (4000) NOT NULL,
  VARCHAR2 (4000) "TASK_DETAILS."
  "CREATED_ON" DATE NOT NULL ACTIVATE.
  DATE 'DONE ',.
  ACTIVATE THE 'CREATED_BY' VARCHAR2 (400) NOT NULL,
  'STATUS' VARCHAR2 (4000).
  DATE OF THE "UPDATED_ON"
  "ON THE ROAD" DATE.
  NUMBER OF "TASK_PREDEFINED_ID."
  "UPDATED_BY' VARCHAR2 (255),
  ACTIVATE THE "USER_NAME" VARCHAR2 (255) NOT NULL,
  'FLEX_01' VARCHAR2 (4000).
  'FLEX_02' VARCHAR2 (4000).
  'FLEX_03' VARCHAR2 (4000).

  'FLEX_05' VARCHAR2 (4000).

  It's good enough that this guy, hope you can help me with this. I'm really stuck on this and I'm about to give up.

  Hello

  So what I have to do is to "force" this relationship 1: n with a hierarchical relationship by creating a query (view) that links the two tables into one and have 2 columns, I can use as ID and PARENT_ID for the creation of the tree.

  I'd say you need a UNION rather than a JOIN.
  Something like:

  WITH project_task_view AS (
   SELECT 'P'||to_char(id) as id
        , null as parent_id
        , project_name as node_name
   FROM eba_task_projects
   UNION ALL
   SELECT 'T'||to_char(id)
        , 'P'||to_char(project_id)
        , task_name
   FROM eba_task_tasks
  )
  SELECT id, parent_id, node_name, level
  FROM project_task_view
  START WITH parent_id IS NULL
  CONNECT BY PRIOR id = parent_id
  ;

• Bind data to the tree?

  Hi all

  I have a result of a webservice (as arraycollection collection)

  I can only say that it contains the categories that have id, name, parentid

  as you can see that the parentid points which, if this category is belong to one id.

  -ID - NAME - ParentID

  1 - cat1 - 0 < < < < 0 means that it is a main category

  2 - cat_sub - 1 < < < < < this category is void cat. of cat1

  3 - cat2 - 0

  4 - cat2_Sub - 3

  5 - cat_sub_sub - 2

  so can I link these data to tree in a simple way?
  What should I do? I don't want to loop at all and look if it's parent or main and where it belongs in and add to the tree.

  Is there an easy way?

• [JDev12c, ADF] Changing the data in the database tables (not)

  Hallo,

  a form obtained from a datacontrol created from a VO based on a query can moidify data in the tables used?

  In general, change tables af:forms to press the button "validate"?

  Some explanation would be appreciated.

  Thank you

  F.

  A commit writes the changes made on the current transaction in the DB. To make changes to the current transaction, you need to change the underlying model. If you use adfbc, that means that you need to make changes to the entity objects. As 1000723 says, vo that does not rely on an EO cannot change the model layer because there's no EO.

• Data of the interactive report not displaying on the edit form.

  I have an interactive report that contains 3 rows. When I click the button change beside one of these lines, the edit form displays the data in this row.
  But when I click the buttons edit beside the other 2 rows of report, I receive an error message that indicates: "ORA-01403: no data found." Error line could not.
  
  I don't see why this is happening. The pharmacokinetics of the table involved is 'Date of application', so 'Column link' report is sent the value "Request Date" to the P54_Request_Date element in the page of the form.
  No idea why this would work properly for one of the lines report but not for the other 2?
  Obviously, each of the lines report must have a value for the PK, then why the form would not be able to find the same line that displays the report? Is this a problem with the process of "line of" form?
  Thank you.

  Hello:

  I'd know it before. The date format default for your application, as shown in the following debug output is DD-MON-RR
  >
  0.35:... "NLS: decimal separator Set =". »
  0.35:... NLS: Set NLS Group separator = ",".
  0.35:... NLS: Date Format Set = "DD-MON-RR.
  >

  So, it means that the part of time to a date column is never taken into account when matching a date field. You can change the default date of the application format (shared components-> change the attributes of the globalization) and the value is in the format that you specified for the column in the report (DD-MON-yyyy hh24miss). It will then do the ARF in the process of work correctly without the need of the value of the page element that contains the column of the massage table. However, the change may affect other pages in your application that may depend on the date is in the format "DD-MON-rr.
  You can try this workaround.
  Remove the header before process you added for re - format the value PK-item page
  Define a process lower than the RFA process before header with a sequence
  Set after a bidding process with a sequence that is lower than the process of automatic line (DML)
  Use the code below for each new process

  execute immediate 'alter session set nls_date_format=''DD-MON-YYYY HHMISS''';

• ODI-17769: OdiRef: internal ID of the SnpSession of the IObjects should not be used when the repository is in mode 12 c

  Hi people,

  I created a variable with refreshing: select '< % = odiRef.getPrevStepLog ("SESS_NO") % >' FROM DUAL

  The error Code is:

  ODI-17769: OdiRef: ID internal 261 of the IObjects SnpSession should not be used when the repository is in mode 12 c.

  Here is a solution for getLoadPlanInstance offered:

  Rittman Mead Consulting"Data Integration tips: ODI 12 c - Substitution API GUID

  based on a "non-written response" by David Allan of Oracle data integration team

  But what of on SESS_NO? Is there a "written response" too?

  Thanx

  Frank

  Hello

  Something like below:

  For example, SESS_NO = "<%=odiRef.getPrevStepLog("SESS_NO")%>". »

  try to replace it by GLOBAL_ID = "<%=odiRef.getPrevStepLog("SESS_GUID")%>." »

  If you use KMs delivered with ODI, you must replace them with their corresponding versions of 12 c.

  If you have your own custom KMs, you must either adjust your KMs to use new odiRef methods that return the GUID of the object.

  or re - upgrade their repositories to use 11 g compatibility mode.

  Thank you

• Tutorial on the impasse, should not block even

  The deadlock tutorial consists of two sons and two objects of a friend: alphonse and gaston
  
  Allows you to call your threads. and Tg.
  
  Ta starts by calling: alphonse.bow (gaston)
  GE starts by calling: gaston.bow (alphonse)
  
  If two threads call the same method 'arc' of separate objects. No conflict.
  
  Ta then calls gaston.bowBack, same Tg call alphonse.bowBack
  
  So the two threads call bowBack, this may or may not be at different times and a call may or may not overlap.
  
  The threads then ask "bowBack" of each object. Again he must avoid any conflict. BUT for some reason, there isn't and this
  What says the tutorial. Well that doesn't matter that each thread calling the same method, they are separate objects.
  This is the case also for when Ta and Tg calling 'Bow' - same different objects of the method.
  SO WHY should the threads will block when the 'same method, different objects' call for bowBack?
  
  WHAT ME MISSING HERE? -J' I seem to have completely missed the point of the example.
  As I understand it, both threads are unable to enter a method synchronized of the same object. So we must avoid a conflict in the example of the tutorial.
  Can someone explain what's wrong with my reasoning?
  
  Published by: 838238 on February 20, 2011 13:12

  To put it another way, if we have two complete different objects (i.e. the data they contain are completely different) and two threads attempt to enter the same method, but operate on different objects, we have a deadlock.

  N ° deadlock occurs when two or more locks are required in different orders of two or more threads. It can occur only in Java if you use locks or synchronization. It has nothing to do with the methods se.

  Given that the threads do not operate on the same data set, it seems unnecessary to have methods synchronized in the first place, unless the threads enter the methods of the same object.

  The deadlock proves that they are the same object blocking.

  So in summary, the "synchronized" keyword requires a very strict on a method lock, even if the discussions do not share the same object/data.

  Fake.

  It does not seem necessary.

  It is incorrect. Your comments on what is locked up are at fault.

• The user should not have Edit access in EA
