Validation required after a selection on Dblink

Hello
whenever I'm getting query select fires on a dblink, even if the transaction is completed and all the lines are read, I wonder commit / rollback of the tool. I need to know that it's fine for any tool, but what happens to the session if the same is launched by a point of view.

I mean, I select a view but that the internal view triggers a query on dblink, in this case only the session remains open or it will be closed by oracle?

Thank you.

  • Validation required according to select choice

    Hello

    I have a selectOneChoice and two input text. The requirement of validation for the two texts of entry is that if the value of selectOneChoice is N, then one of two text entry have a value.

    I wrote and directed the bean validator method and plug the two texts of entry: validator = "#{pageFlowScope.bankAccount.validateOtherBank} '"

    The problem is that when you submit the form, the validator is not called. I guess that's because the two text input values are empty.

    How do you validate one of the two text entry are not empty according to the value of the selectOneChoice?

    Thank you

    JDev 11.1.2.4

    Yes, this way you are sure that the validation is performed and that you don't have to worry about the order in which the fields are defined.

  • Commit after a select query

    We need to commit after a select statement in all cases (in any mode of transaction)?

    Why do we need to commit after selection in a table to a different database using a DB link?

    If I run a SQL query, it really starts a transaction in the database?
    I couldn't find any entry in v$ transaction after execution of a select statement that involves no transaction is started.

    Yes you need to issue COMMIT or ROLLBACK, but only if you issue a ' SELECT... UPDATE ' because that locks the selected lines and they will stay locked until this just released. Other sessions trying to update one of your locked lines will block until this that released or get

    In DB2 SELECT create share locks on the rows and updates of these lines, by other sessions can be blocked by locks of sharing. So, the custom is to COMMIT or ROLLBACK after a select statement.

    Why it seems that a SELECT statement on a db_link requires a validation after running?

    It's here. When Oracle executes a distributed query to SQL Oracle holds an entry in the segment field of restoration for the treatment of the validation in two phases. This entry is maintained until the SQL statement is committed even if the SQL statement is a query.

    If the application code does not address a commit after the remote or distributed select statement then the entrance of rollback segments is not released. If the program remains connected to Oracle will but idle for a while (like a demon, waiting for alert, waiting at the entrance to the mailbox, etc...) so when Oracle should wrap around and reuse the scope, Oracle must extend the rollback segment because the remote transaction still holds its scope. This can result in segments rollback extending until their limit of measurement or consume all the free space in the tablespace rbs even when there is no major transaction in the application. When the rollback segment tablespace is created using expandable files, then the files may end up growth well beyond any reasonable size needed to support the load of the transaction to the database. Developers are often not aware of the need to engage with distributed queries and thus often create distributed applications cause, experience or contribute to the restoration of the segment of the related problems as ORA-01650 (impossible to extend rollback). The requirement to commit distributed SQL exists even with cancellation automatic management available with version 9 and newer. If the segment is occupied by a uncommitted distributed transaction, oracle will have to either create a new rollback segment to organize new operations or expand an existing one. Eventually undo space could be exhausted here, but before that, it is likely that data will be discarded before the undo_retention period has expired.

    Note that by the distributed manual a SQL remote is one that refers to all of its objects in a remote database so that the statement is sent to the site to be treated and the result is returned in the proceeding, even if a distributed transaction is one that refers to objects in multiple databases. For the purposes of this FAQ, there is no difference, because both must commit after any form of distributed query is issued.

    The field calculation order is probably not set correctly. The specific configuration procedure it depends on which version of Acrobat you are using. Acrobat 11, you would go first in forms editing mode (Tools > forms > change), and then select:

  • Bypass Validation required field required in dynamic form PDF

    I faced a difficult situation, where some fields are required, but we need allow the rule of validation (required) required bypass when you save the form and require to fill in these fields when you submit the form. In other words, to allow a flexible control when to enable / disable this feature.

    I wanted to put in place a flexible solution, and I will post my findings here. Appreciate your comments to improve.

    Steps to follow:

    1. mark the fields returned as required.

    2 specify 'Empty Message' as "this field can not be empty", or similar.

    3. specify the "Message of Script Validation" as 'this field must have a correct value before submitting', or similar.

    4. create a Global Variable-level form something like 'StopTotalValidation' and '1' as the default means default, turn off Validation for some cases.

    5. for areas that require this type of control, add the script (to be defined later) on the event to "validate":

    myTools.validateForRequiredField (the);

    6. create a Script object "myTools" and add the following script:

    function initStringFunc() { }

    Call this function to initialize Document

    String.prototype.Trim = function() {}

    return this.replace(/^\s+|\s+$/g,"");

    }

    String.prototype.LTrim = function() {}

    Return this.replace (/ ^-s+ /,' ");

    }

    String.prototype.RTrim = function() {}

    Return this.replace (/------s+$/,' ");

    }

    String.prototype.isEmpty = function() {}

    return (this == null) || "This.Trim ( == );"

    }

    }

    function setNodeProperty (, of theNode Dubien newValue) { }

    if (theNode [property] ! = newValue) {

    theNode [property] = newValue;

    }

    }

    function isNodePropertyEmpty (theNode, property) { }

        var result;

        if (theNode == null || theNode [theProperty] == null) {

            result = true;

        } else {

    result = theNode [theProperty] .isEmpty ();

        }

    returns the result;

    }

    function disableTotalValidation() { }

    StopTotalValidation.value = '1';

    }

    function enableTotalValidation() { }

    StopTotalValidation.value = '0';

    }

    function isTotalValidationOn() { }

    back StopTotalValidation.value ! = '1';

    }

    function isTotalValidationOff() { }

    back StopTotalValidation.value == '1';

    }

    const conRequired = '(mandatory)';

    function validateForRequiredField (theFld) { }

        //

    / / Bypass required field Validation when the overall Validation is OFF.

        //

        var result = false ;

        if (theFld) { }

    If (theFld.mandatory & & theFld.mandatory == "error") { }

    If (myTools.isNodePropertyEmpty (theFld, "rawValue")) { }

    myTools.setNodeProperty (theFld, "rawValue" conRequired);

                }

    If (isTotalValidationOn()) { }

    If (isNodePropertyEmpty (theFld, "rawValue") | ) theFld.rawValue.toLowerCase) == conRequired.toLowerCase ()) {

                        result = false;

                    } else {

                        result = true;

                    }

                } else {

                    result = true;             

                }

            }

        } else {

            result = false;

        }

    returns the result;

    }

    7. now click on the button 'save' call the function "disableTotalValidation()" and click on the button 'submit' call the function "enableTotalValidation()".

    I just finished the implementation of the solution above, and according to my initial tests, it works fine.

    I'll post this to my Google Docs workspaceand provide updates their.

    T arek.

    Hi Niall,

    In fact, it is not that some require and some do not need validation...!

    The fact is that fields that are 'Required' rule ignored should only and only if the form is "saved" from the Save"" button.

    The 'Required' rule should be triggered only and only the user is clicking on the submit"" button.

    I think I can make use of your approach. The only problem I see now is how to mark the item of of these fields with the details the user of LiveCycle Desinger interface requires? This means, I have to call a script on the initialize event of these areas, which is more work and more confusing for other developers. As I use a non-standard feature of the interface user Desinger.

    In my case, I added a simple invocation of the event 'validate' to a common function for all areas that need to follow this simple rule "bypass validation required...". »

    But, I really like your solution. In fact, I understand what you're doing, but now the following questions are triggered:

    1. What is the meaning of three time equal (=) in the statement of JavaScript "if"?

    2 I need more information on the use of methods 'createNode()' and 'namedItem().

    Tarek.

  • A. first 6.5 farm after the selection of the project to open it?

    From yesterday, Adobe Premiere 6.5 (using XP on an old Dell PC) goes through fine, opening sequences but just after I selected the project I would like to change-it is FARM with message ' AP has encounter a problem and must close.  We are sorry for the inconvenience. Please tell Microsoft to solve problems.  Click on send error report. I have restored to the times previously without success and I re-install Adobe 6.5, then uninstalled and reinstalled Adobe 6.5 with the same results...  I'm dead in the water and got mounds of work I have to do... You have any other suggestions?  Side, I tried to work wrapper - opening a new project, nothing helps. The last time, that I have edited... 2 days ago I noticed when you turn on, an unusual display came to ask me how I wanted to edit in AB mode or in the technical right?  And when I chose the path of AB, I noticed it was not all highlighted these PAST CLIPS or PROJECTS RECENT tab file (upper-left) and I've NEVER seen this before... and now when I click recent projects today, it shows me with only 5 projects (new, I created 2 days ago (that's because the list is new?) There was ALWAYS some 10 projects listed before, the last 10 accessible.  Don't know if this has anything to do with him or not, but that he thought it was important.  Thanks for the thoughts you may have!  Dee douglas.

    FOR INFO.  Finally, I corrected my FINAL message as soon as I picked my PROJECT to reinstall a new operating system... Clean the drive C and added XP Pro and Adobe Premiere 6.5 and it seems to work very well.  Drastic measure, but it cuts the hunt.  CDI

  • dataProvider add article before or after the selected line

    Hi, guys.

    As we know, we can add an element in a data grid by simply call

    DG1. DataProvider. addItem (x: object)

    I wonder if there is a specific function as addItemAt(x: object, y) who takes an additional number of index as a parameter

    Finally, users want to add a new line before or after the selected line in the data grid.

    Thank you!

    Alex

    Collection ArrayCollection subclasses ListCollectionView.  ListCollectionView contains the function you are looking for, addItemAt (item: Object, int index).

    Sincerely,

  • Performing validation after a select

    We were chasing a bug and found the culprit to be:

    SQLExecute (any SELECT statement)
    SQLTransact (commit)
    SQLFetch()

    The validation in the workplace caused an error of invalid execution command. We have removed all the commits of the SELECT statements and everything seems to be fine now.

    But, what does commit a statement SELECT actually? We assumed (wrongly) that it would have no effect.

    When you SQLExecute() a SELECTION, or indeed run any ODBC call that returns a set of results (potentially), you open a cursor. This cursor is associated with the ODBC statement handlle which in turn is associated with the handle of the connection it was distributed of which in turn is associated with the environment handle that it has been distributed. This slider must be open in order for this result set SQLFetch(). A validation on a connection closes all cursors open on any handles associated with this connection, where the error on the later SQLFetch().

    Some databases support both cursor behaviors alternative; preserve in the validation set or close the commit. Some never close the commit. TimesTen always ends the commit.

    In general you don't need to commit executions SELECT TimesTen, but:

    1. If you do not then you must remember to close the cursor opened using SQLFreeStmt (hstmt, SQL_CLOSE) before you try to rerun the SQLExecute() (or better yet, as soon as you have finished SQLFetch() ing him) or you can get other errors of sequence later or same resource leaks.

    2. Since the same SELECTION starts a transaction you need to either validation or cancellation until you try and deliver a SQLDisconnect() or disconnection will fail.

  • Assistance required after you download Sierra - locked in a spiral of failure of the Installation

    Hello - I am a student of the University who made the mistake of thinking I had to upgrade my OS system after seeing some updates new flashy in the Sierra. Long story short, that my computer is locked into a cycle where I restarts and the installation process will begin installation but end abruptly and ask me to reboot again.

    I have exams and papers due and seriously want access to my data again. I don't have a back up of my files. As such, I am looking for a method that will allow me access to my files that I need to be able to read notes, print etc.

    Details: I have an old MBPro by the end of 2011. He was on as the primary OS x Lion. I had updated some time later. More recently, I got El Capitan and it worked very well. I downloaded Sierra in the background as I did work at home and after installing it, it asked me to reboot. This was the point that I was able to come back from. Reboot after installation scenario is as follows:

    -A progress bar comes up saying 34 minutes until completion

    -The progress bar goes to 33 minutes until completion

    -Beginning of fans of my computer acting upward and the bar stops and crashes of progression

    -The installation process says he doesn't have and asks me to restart my computer

    Specifically, I get the message 'Mac OS could not be installed on your computer. File system check or repair a failure. Quit the installer to restart your computer and try again. »

    When I quit the installer of the OS, I am taken to the startup disk option and asked to choose a system to reboot my computer with. I see 'Macintosh HD macOS 10.11.4' but when I click on it and try to restart I get the following error message, "you cannot change the disk on the disk selected. Startup disk could not gather enough information on the selected disk. »

    Things I've tried:

    Internet recovery mode: I went here to do a restore of the Mac OS x comes with my computer (Lion). This attempt fails and the computer tells me I can't downgrade because a more recent OSX is already on my computer...

    Recovery mode: I tried to come back just El Capitan from here. When I try to do the process will take literally one second before I get a notification saying: "an error occurred during the preparation of the installation. Try to rerun this application".

    Disk utility: I tried to do first aid and repair on this menu on the big disk image (since some of them pop up... I'm sure that the big one is my computer and the small setup of Sierra is?). I see that I 115Gigs franco 319Gigs departure. When I click on check and repair, the process takes some time and seems as he goes to halfway through before I get errors in the two. Repair error wonder backup my data.

    -some specific stuff; the journal for the repair of first aid says something like: the Macintosh HD volume could not be completely checked. File system check exit code is 8. Update support partition for the volume as required. File system check or repair a failure. Operation failed... »

    Safe mode: I can't start in safe mode. My computer will load the apple logo, progress on 3/4ths of the way start-up and then crash on its own and not restart.

    Things I have tried:

    Constituting a new boot USB of OS Sierra - I read that in so doing I can substitute the installation process that is going on right now on my computer and start a new... I hope one that works. I was not able to do this again, because I need someone to another macbook to make it and none of my friends won't let me touch their computers after the fiasco that happened on mine... Can I get some feedback on this?

    Backup: I don't have an external hard drive... I'm willing to buy one if necessary, but I don't know how to make a backup in a world where I don't have access to the major functional sections of my computer. Also, if my computer is * session here now, I'm worried that a backup will be essentially a * a backup... is this the work of the computer?

    Other thoughts:

    -my computer was working fine before I tried the upgrade... no complaints on my end, it was a real trooper

    -Maybe the download was corrupted?

    -I learned today that the operating system installation process requires internet connection - maybe that my internet connection is bad?

    -on that note, I want to say I tried a lot of different things. Been in different parts of the campus (different parts of my dorm building, IT support across campus, etc.). My University has also 3 options of WIFI, but each requires a separate verification process. Throughout this process, I have been connected to one of these methods. Switching may help? But, if I can't do the verification step (i.e. open a browser and type in the details of my student specific to actually use the web), I do not think that this will help you a lot. In addition, I am sure that I am already using one of the less frequently used options.

    I want to avoid a permanent possible deletion because there are important things on my computer.

    Any advice? Enjoy it!

    Same problem here on my Mac Mini end of 2012. I couldn't find any fix so far. The machine worked perfectly fine before with El Capitan and had about 50 GB of available disk space. I have use any version beta of Sierra, but officially released one that came yesterday. Really disappointing to see the new system operating software with fundamental questions and no good way to solve it.

    Any help really appreciated.
