SYS_CONTEXT return do not results

Hi - noobie question, sorry in advance.

I am a student at OCA, and I came across a feature called SYS_CONTEXT

[http://docs.oracle.com/cd/E11882_01/server.112/e26088/functions184.htm#SQLRF06117]

I'm trying to retrieve my IP using SYS_CONTEXT ('USERENV', 'IPAddress'). SQL * more accepting but nothing back and I don't know why. I tried a few arguments (e.g. SYS_CONTEXT (' USERENV', 'AUTHENTICATION_DATA' ") but still nothing is returned.) Still using USERENV as I believe that it is the namespace built into Oracle.

all the tips at this stage.

PS I am connected to OracleXE as SYSTEM

How you connect to the database? And it is a database that is installed on your local computer?

If you use SQL * more

sqlplus scott/tiger

creates a connection needed to the database. You're not going via TCP/IP so that you have an IP address.

sqlplus scott/tiger@tns_alias

will go over TCP/IP to the listener and create a 'normal' connection that will have an IP address.

CFEXECUTE / ant script return do not result in the CF
I have a batch script that is running an ant script that is running "cvs log h application.cfm" on the cvs server.

When I run the script commands manually on the command line, everything works fine.

When I run the command via CFEXECUTE script, the batch works very well, the ant script works fine, but the cvs command does not seem to do anything. The results of the tag are:
[echo] front
[echo] after

As you will see the (unchanged with the exception of the cvsroot attribute) attached ant script, echoes are and part of the cvs command.
When running from the command line, I get the results of the cvs log command between these lines, but I get nothing with the CF.

Any ideas on how to get this to work at all will be greatly appreciated.

I use 7.01, but I corrected the tag CFEXECUTE by restarting the service CF twice.

I also managed to finally get the CVS little work - changing : ext: to : ssh: -which I'm sure I've tried before and it wouldn't work, but it works now so I'm very happy.

I put my date 17.06.2009 system.
When I run

select * from semestru where data_start=sysdate i got no results. Why?

Regards,

Don't forget SYSDATE is inclusive of seconds, so you need to TRUNC he put at midnight.

Try:

select * from semestru where data_start=TRUNC(sysdate);

And if that doesn't work, try:

select * from semestru where TRUNC(data_start)=TRUNC(sysdate);

I have the following function within a package:
```

    p_appery_user_id IN APPERY_JTI_deleted_USERS.appery_user_id%TYPE,

```
The function called several times as part of a job. Basically, the main function (Say M), call a few functions (for example A1... A9). Each of these functions is to do something and updated the application using the above function. Therefore, each of the nine functions will call the above function with different parameters.
The problem that I am facing is:
First run, invoke only first of all for the above function will return the positive result ($sql rowcount > 0). When I run M the second time, only first and second calls for the above function will be to return positive results and so on.
How odd, it's that if I change the values again and run a function M, it will start from the beginning. And what strange more, the dynamic update statement is executed correctly and data are updated successfully. It's just sql rowcount % do not return is not the expected results.
I tried to run execute immediately without (begin, end). I also tried to run it without HELP ON. It's always the same. I'm really confused, what Miss me here.
I don't know if this is relevant. But for what it's worth, invoking the function above updates the SAME lines in the table appery_jti_deleted_users that the columns are different. So for all the work, the same lines need to be updated. Each function (A1... A9) will call the above function to update a different column of these lines.

If you REALLY want to help you having US SHOW, not tell us:

1. WHAT you do

Yet once you showed us NOTHING >

You do NOT FOLLOW best practices when you use dynamic sql statements: the sql statement real so that you can print:

1 SEE what's running - make sure there are no syntax errors, and it seems to be what you wanted

2 EXECUTE/TEST manually - to see if he really runs without error and see what results it really give.

3. FIX any syntax or other problems and retest it

Instrument properly your code and you won't have the problems you are having.

You should know by now what are the parameters are transmitted when you run the function. So, there are at least three sets of these parameters.

So you should be able to:

1 run the instrumented manually function three times

2. see that all three SQL statements are

3 manually run these instructions

4. see that the number of lines is after each execution

We have no idea of what the output of the function is every time you call it. Apparently, you have, if you save the results of the function somewhere, but you didn't post any of this info.

We need real details to help you - just listen to your story is not enough.

Simple find() return is not the expected results

I'm new to ColdFusion, but have been programming for a while now. I have (what seems) an easy problem that I thought would be a simple solution, but I'm currently stuck. Any guidance would be appreciated!
I have the following code:
< cfset brand = Trim (products. BRAND name) / >
< cfif Find (brand name, ",") >
< cfset brand = ""' & brand & ' "" / >
< / cfif >
My goal is to surround the text with 'if the string contains a comma. I tried the standard comma, as Chr (44), but neither returned the expected results.
What I am doing wrong? The CSV file, creating, is sprayed upward for the name of a company is like 'Test Company, Inc.'
Please help us save my sanity! TIA!

I think the first thing we do is to read the docs. And if you may have read 'em a little closer... ;-)

vCACCAFEEntitiesFinder.getMachinePrefixes (vCACCafeHost) returns only 25 results

vRA 6.2.2 Build - 2754020
vRO 6.0.1
With the help of vCACCAFEEntitiesFinder.getMachinePrefixes (vCACCafeHost) returns only 25 results when there is more than 25 Machine prefixes.
The documentation for this method "Gets all prefixes for a host machine" - but apparently not to collect them all if there are more than 25.
I also tried the built in getAvailableMachinePrefixes workflow that uses vCACCAFEEntitiesFinder.findMachinePrefixes (host, query), but that seems to have the same problem when there are more than 25.
All this experience / have a way around it?

This was bugs me because we talked last... This seems to work & survives when I throw a lot of prefixes to it :-)

When prefWidth() and prefHeight() return the correct results
The functions Node.prefWidth () and Node.prefHeight () return 0 after a node is created (for example after the new Button("xyz"). - then "suddenly" (for example when being positioned in layoutChildren() of a component) they return correct return values.)

That is the trigger to make the knots return a correct result of prefWidth/prefHeight? Is there a way to directly get the correct prefWidth/prefHeight just after creating an instance of the component?

Thanks for any indication on that!

A few examples: an extension component for the simple layoutChildren() method in which the three buttons are added. The prefWidth/prefHeight is output to the console:
```
public class Test_39_PrefWidth extends Application
{
    public static void main(String[] args) { launch(args); }

    class MyPane extends Pane
    {
        protected void layoutChildren()
        {
            double y = 0;
            sysoutNodePrefSizes("----- doing the layout");
            for (Node child: getChildren())
            {
                double childWidth = child.prefWidth(-1);
                double childHeight = child.prefHeight(-1);
                child.resizeRelocate(0,y,childWidth,childHeight);
                y = y + childHeight;
            }
        }
    }
    
    MyPane m_pane;
    
    public void start(Stage primaryStage)
    {
        final Scene scene = SceneBuilder.create()
             .root
             (
                 m_pane = new MyPane()
             )
             .build();
        for (int i=0; i<3; i++)
        {
            Button b = new Button("Hello " + i);
            m_pane.getChildren().add(b);
        }
        sysoutNodePrefSizes("------ having created and added the buttons");
        primaryStage.setScene(scene);
        sysoutNodePrefSizes("------ having assigned the scene");
        primaryStage.show();
        sysoutNodePrefSizes("------ having called stage.show");
    }
    
    private void sysoutNodePrefSizes(String title)
    {
        System.out.println(title);
        for (Node child: m_pane.getChildren())
            System.out.println(child.prefWidth(-1) +  "/" + child.prefHeight(-1));
    }
}
```
The result in the console is:
-have created and added the buttons
0.0/0.0
0.0/0.0
0.0/0.0
-have assigned to the scene
0.0/0.0

The size of a knot is not known, until it has been laid out. It is not arranged until after it has been added to the scene. Setting in page happens during a pulse, so you add the node to the stage and then is placed on the next pulse.

Because a node could be affected by a CSS style and the styles that apply to a dependent node when the node is in the graphic scene, it is not possible to get prefWidth/prefHeight without adding the node to the graphic scene. This is a problem and there must be a method 'size this node as if it was added to that parent in the scene graph', but it is not one now.

Firefox on Android sync returns "could not sign."

I have Firefox for Android beta v39 and Firefox for Android v38 installed on my phone (Lollipop 5.0.2) and little matter which of these browsers, I try, when I have connection for synchronization, it gives the message "Unable to connect"... I have installed on my linux desktop v38 and it works with the same credentials. I tried to reset the password, and it also does not help, because the problem is always the same... Desktop Sync works and it does not work on Android. Any suggestions?

I understand that Firefox for Android returns: "could not sign" I am happy to help you. Let's try a new connection by removing the account first.
1. First unplug the account settings under 'Accounts' Android
2. After listening to remove, open a new window in Firefox
3. Go to https://accounts.firefox.com
4. Connect once more and make sure that in your account settings, that data usage is set to auto sync.

Oracle text index does not return the expected results.

Hello

My project requires a generic search on 5 different columns and all the VARCHAR2 data type.
As performance is very slow with AS % search, I try to use for the multi_column_datastore that is recommended for this.

Here's what I did.

1 - Create table.

CREATE TABLE BILLING_SCHEMA.NAMES_TABLE ( 
    ID                  NUMBER(9,0) NOT NULL,
    ENTITY_NUMBER         VARCHAR2(30) NOT NULL,
    GIVEN_NAMES         VARCHAR2(50) NULL,
    SURNAME             VARCHAR2(30) NULL,
    ORGANISATION_NAME     VARCHAR2(60) NULL,
    DISPLAY_NAME        VARCHAR2(100) NULL 
    )
/

My search must be made on the columns ENTITY_NUMBER, GIVEN_NAMES, surname, ORGANISATION_NAME and DISPLAY_NAME.

2. - insert values into the table

INSERT INTO NAMES_TABLE VALUES(1, 'GH', NULL, NULL, NULL, 'GROUP OF HOSPITAL')
/
INSERT INTO NAMES_TABLE VALUES(2, 'DH', NULL, NULL, NULL, 'DEPARTMENT OF HEALTH')
/
INSERT INTO NAMES_TABLE VALUES(3, 'REC', NULL, NULL, NULL, 'DEBTOR FOR RECEIPTS')
/
INSERT INTO NAMES_TABLE VALUES(4, 'UN_REC', NULL, NULL, NULL, 'DEBTOR FOR UNMATCHED RECEIPTS')
/
INSERT INTO NAMES_TABLE VALUES(5, 'SAM_FUND', NULL, NULL, NULL, 'THE S FUND')
/

3 - create context multi_column_datastore index

BEGIN
CTX_DDL.CREATE_PREFERENCE('NAMES_TABLE_MULTI', 'MULTI_COLUMN_DATASTORE');
CTX_DDL.SET_ATTRIBUTE('NAMES_TABLE_MULTI', 'COLUMNS', 'ENTITY_NUMBER, GIVEN_NAMES, SURNAME, ORGANISATION_NAME, DISPLAY_NAME');
END;

CREATE INDEX NAMES_TABLE_IDX
ON NAMES_TABLE(ENTITY_NUMBER)
INDEXTYPE IS   CTXSYS.CONTEXT
PARAMETERS ('DATASTORE NAMES_TABLE_MULTI')

4 - create the trigger that should update the column ENTITY_NUMBER if everything is inserted/updated

CREATE OR REPLACE TRIGGER NAMES_TABLE_TRIGGER
BEFORE INSERT OR UPDATE OF GIVEN_NAMES, SURNAME, ORGANISATION_NAME, DISPLAY_NAME  ON NAMES_TABLE
FOR EACH ROW
BEGIN
  :NEW.ENTITY_NUMBER := :NEW.ENTITY_NUMBER;
END

5. the search query

SELECT *
FROM NAMES_TABLE
WHERE  CONTAINS(ENTITY_NUMBER,'%TH%') > 0

I am so very confused here because the result returned is only

ID     ENTITY_NUMBER     GIVEN_NAMES     SURNAME     ORGANISATION_NAME     DISPLAY_NAME         
 2      DH                  (null)        (null)         (null)          DEPARTMENT OF HEALTH

When I wait for him that the 5th inserted record is returned too as it contains "THE S FUND" that begins with "TH".

When I use the search string '% %' and %, no results are returned, although I expect at least two records in each case.

I would appreciate help with this.

Thanks in advance,
Marilyn

Validator do not return is not the results.

Hi all

I extended the StringValidator class in order to create a user name validator. When a new user is registered, the user name is validated on the server to check if it exists.

The code is not thrown error and I know the remoteobject calls to work. The push sets the message, but the problem is that the result is not returned.

The flow is correct?

public class PosUsernameValidator extends StringValidator {
          
          private var userServiceRO:RemoteObject = new RemoteObject();
          private var validatorResults:Array = new Array();
          
          public function PosUsernameValidator(){
               super();
               userServiceRO.destination = "UserService";
               userServiceRO.getUserByUserName.addEventListener("result", getUserByUserNameRH);
               userServiceRO.getUserByUserName.addEventListener("fault", getUserByUserNameFH)
          }
          
          override protected function doValidation(value:Object):Array {
               validatorResults = super.doValidation(value); 
               return doForUserName(value);
          }
          
          private function doForUserName(value:Object):Array{
               userServiceRO.getUserByUserName(String(value));
               return validatorResults;
          }
          
          private function getUserByUserNameRH(r:ResultEvent, t:Object = null):void{
               var user:User = r.result as User;
               if(user!=null){
                    validatorResults.push(new ValidationResult(true, null, "Username error","Username already taken!"));
               }
          }
          
          private function getUserByUserNameFH(f:FaultEvent, t:Object = null):void{
               Alert.show(ObjectUtil.toString(f));
          }
          
     }

Once the error message string from the server side, link it to property 'errorString' of any component of entry, you want to display the error on. This will give you the red border and a ScreenTip as if you used a validator. Don't forget to set the error return string to "" to clear the message once validation passes.
