Using Sleep Function in Flex
Hi,
I have something here which takes some time for the
HTTPService to communicate with an external server that hosts the
database. The only issue here is that when I would like to change
the view state to see the information, the application cannot
handle it on the DataGrid due to the time lapse.
In programming languages, there is a function called sleep
that I can stop the program till certain stage is committed. In
Flex, I tried to use setInterval(1000) to commit 10 seconds to put
the program to sleep, but most manuals require me to apply
setInterval with a function or two. Could I just do
setInterval(1000) for my program to sleep for 10 seconds instead of
waiting for it to apply to another function in Flex?
Thanks in advance.

Hi,
As Dmitri mentioned, you should listen to the result event of
the HTTPService. HTTPService calls to the server are asynchronous,
so HTTPService will dispatch a result event when the response from
the server is received.
Please find more details on how to listen for result and
fault events of the HTTPService at the URL below.

You can also have a look at concept called Binding in Flex.
This will allow you to bind your DataGrid to a ArrayCollection and
when the ArrayCollection is modified, your DataGrid will reflect
the changes. Please find more details on Binding at the URL below.

Hope this helps.

Need help in using sleep function in pl/sql
Hi,
need help:
I have a condition where i want to validate total_pass=total_fail and
I want to use the sleep function in a pl/sql where i want to wait for 2 minutes ie.checking
whether total_pass=total_fail based upon class_id .
I have the data in the table as:
CLASS_ID TOT_PASS TOT_FAIL
1 10 10
2 5 4
3 6 6
4 7 5
Any help will be needful for meI'm not quite sure what you are lookg for here, but whatever it is, your code as posted won't do it. You will never break out of the WHILE r_Class.Tot_Pass = r_Class.Tot_Fail loop, since these values will never change because you never get the next record form the cursor.
From your original data, it looks like your cursor will return multiple rows which implies to me that you want to fetch the first row from the cursor, check if tot_pass = tot_fail, if they are equal, sleep for two minutes then get the next row. This does not make sense to me. Once the select in the cursor is executed, the data it returns will not change due to Oracle's read consistency model, so there seems to me no point in the sleep.
The other alternative I can see is that you want to check all the returned rows, and if tot_pass = tot_fail for one of the rows (or possibly for all of the rows), then you want to sleep and try again.
If you can explain in words what it is you are trying to accomplish, someone will be able to point you to a solution.

Hi,
I have used sleep function in my pl/sql code. I have written the code as below:
create or replace package ab is
procedure def ;
PROCEDURE TEST_SLEEP(TIME1 NUMBER);
end ab;
create or replace package body ab is
PROCEDURE TEST_SLEEP
TIME1 IN NUMBER
) IS
BEGIN
DBMS_LOCK.sleep(TIME1);
END TEST_SLEEP;
procedure def is
begin
for i in 1 .. 5 loop
if i=5 then
TEST_SLEEP(i);
DBMS_OUTPUT.PUT_LINE(I);
end if;
if i=1 then
TEST_SLEEP(i);
DBMS_OUTPUT.PUT_LINE(I);
end if;
if i=3 then
TEST_SLEEP(i);
DBMS_OUTPUT.PUT_LINE(I);
end if;
if i=4 then
TEST_SLEEP(i);
DBMS_OUTPUT.PUT_LINE(I);
end if;
end loop;
end def;
end ab;
and every time iam calling that procedure to sleep for some time and display the output through def procedure. But in this the output is displaying for all conditions at the end of execution.
any one help me please.

ya we can recode it to simplify the code. But my requirement is to print the output that shows the time difference of an execution. That does not mean that one can now forget about simplifying the code. The art of programming is to achieve the requirements with as few lines of code as possible. Simplicity is the ultimate form of elegance.
At the end of procedure execution the output is displaying normally, but i want the output to display everytime it satisfies the condition. By this I can see that its delaying the execution everytime when it enters into the conditional statements.Do not really understand what the requirement is that you describe. Keep in mind that PL/SQL code is server-side code. It run inside a server process.
So the client makes a PL/SQL: begin MyPackage.FooProc( :var1 ); end;
This is received by the server. Is parsed. Is executed. And the COMPLETE call is executed. Including all DBMS_OUTPUT calls.
The call is completed. The client gets the response code that says it was successful.
The client now makes another call - it requests the DBMS_OUTPUT buffer from the session. It receives the contents from the server and renders it.
DBMS_OUTPUT is NOT an interactive display device. It does NOT write to the client display. -
I can't use the sleep functions, is it a bug?
i just updated my Ipod to 1.2 .And i found the sleep function is not available. there is no menu to set the sleep time. when i put the sleep menu , my nano turns off immediately. is it a software bug?
i have had the answer.
the sleep function can't be used as a sleep timer.the sleep timer is set in clock menu. -
External FW/USB Western Digital, Seagate Disk Drives and 'Sleep' function
As you are aware, most external disk drives be they FW or USB (and irrespective of the manufacturer, save for LaCie) have a 'sleep' function built into their Firmware. In the case of the Western Digital and Seagate Ext FW drives I have, this function cannot be disabled and this per both WD and Seagate.
Unfortunately this is extremely annoying if using Photoshop and Bridge...it takes about ten seconds for each disk to spin up while the latter programs search the drives. (In Windows this can be enabled/disabled. Not so with the Mac O/S I have been told). Multiply this by six of the aforementioned drives and it can be quite time consuming.
Is there an OS-X workaround for this?
Thanks again,
LymanI always avoid vendor cases. Might want to look at an Oxford 912 etc, or better yet, why use Firewire when eSATA works so well?

Why I cannot use search function in my apple store? I use Ipad 3 and it is the latest software
Why I cannot use search function in the apple store on my ipad?
Nobody here could possibly answer your question as presented. Have you tried any troubleshooting steps at all?
Quit the app store completely and reboot the iPad. Go to the home screen first by tapping the home button. Double tap the home button and the recents tray will appear with all of your recent apps displayed at the bottom. Tap and hold down on any app icon until it begins to wiggle. Tap the minus sign in the upper left corner of the app that you want to close. Tap the home button or anywhere above the task bar.
Reboot the iPad by holding down on the sleep and home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider if it appears on the screen - let go of the buttons. Let the iPad start up.
If that doesn't work ... A few more details from you might help you get your problem resolved. -
Hi Guys,
I am creating a procedure which will check for the fileld in the database and if it returns NULL should go to sleep for 15 minutes and then will again check for the field. I am planning to use DBMS_LOCK.SLEEP function. Please can you suggest if the same is fine or advise if in case there is any other specific function which I require to use as I have read that the mentioned function is not accurate in calculating the SLEEP time.

ShazSummary of DBMS_LOCK Subprograms
Table 53-3 DBMS_LOCK Package Subprograms
Subprogram Description
ALLOCATE_UNIQUE Procedure
Allocates a unique lock ID to a named lock.
CONVERT Function
Converts a lock from one mode to another.
RELEASE Function
Releases a lock.
REQUEST Function
Requests a lock of a specific mode.
SLEEP Procedure
Puts a procedure to sleep for a specific time.
PL/SQL lock timer
Definition: This Wait-Event represents the amount of time a user or application has “slept” through the USER_LOCK.SLEEP or DBMS_LOCK.SLEEP procedures.
When investigating Oracle Wait-Events, the lion's share of time is spent looking at those events where applications consume precious system resources or are in direct contention with other users or applications. These resource waits revolve around excessive CPU, memory, or disk usage. Events that spin for Oracle internal structures such as latches or enqueues can also be of concern. As their name suggests, Wait-Events DO ‘wait’ on some event to complete before a user or application can continue with its work. Contention for system resources will overwhelm Oracle’s ability to immediately process the SQL and ultimately cause applications to accumulate time in resource specific Wait-Events.
On the flip-side of resource waits there are what are called idle events. These events do not wait for any specific resource but record the time Oracle is waiting for a work request from the application. Many practitioners of Oracle performance will not even look at these idle events because they do not consume resources and are not limiting what Oracle can do at any given point in time. Some will even go so far as to state that the idle events have no meaningful information. This is not necessarily true. Take for instance the idle event ‘SQL*Net message from client’. This idle event is not inhibiting the database server from performing work but, as many agree, is an indication of poor response from client to database server. While idle events are not the result of direct resource contention, they are an accurate measure of accumulated delays in the application imposed by Oracle.
The ‘idle’ event “PL/SQL lock timer” is worth watching because it points us in the direction of application response, throughput, and possible coding issues. The PL/SQL lock timer event is, as the command that issues it states, a sleep mandated by the application code. The application is idle and doing nothing. This means that if the application sleeps for a combined interval of 5 minutes, the response to the user or complete run of the application will take at least 5 minutes longer.
While this event does not require resources and thus is not an Oracle resource contention issue, it is our job to provide the quickest response to users and push applications through our system to increase the user’s perceived performance.
Most often, sleeps are put into an application for serialization of transactional events or spinning on queues until something happens. When the event occurs or a queue is populated, then the application continues its work. We should ask ourselves why an application is sleeping for any amount of time and provide alternatives if necessary to reduce this idle event. You will gain quicker responses if you trigger an action instead of the action waiting for an event.
How to look at the PL/SQL lock timer event
To initiate a sleep for the current session for five seconds.
SQL> execute sys.dbms_lock.sleep(5);
To take a look at current sessions that are using the SLEEP command. Notice that the column P1 in V$SESSION does not represent the amount of time the session has slept but in fact represents the duration this session will sleep. Also note that this column is in centiseconds and as such the five seconds issued for a sleep has been translated in to 500 centiseconds.
SQL> select osuser,event,p1 from v$session where event = 'PL/SQL lock timer'
OSUSER EVENT P1

Can not use TOUCH function on Nokia 6600 slide
Can not use TOUCH function on Nokia 6600 slide-
turned on sensor in phone settings, but when i touch the PHONE it does not work.
Please, tell me how use this function or maybe my phone is out of orderAs long as your Sensor Settings are On within Menu, Settings, Phone, Sensor Settings then you just need to do the following -
Tapping
The tap function allows you to quickly
mute and reject calls and alarm tones, and
to display a clock just by double-tapping
the back or front of the phone when the
slide is closed.
Select Menu > Settings > Phone >
Sensor settings to activate the tap
function and vibration feedback.
Mute calls or alarms
Double-tap the phone.
Reject a call or snooze an alarm after
muting it
Double-tap the phone again.
Display the clock
Double-tap the phone.
(If you have missed calls or received new
messages, you must view them before you
can see the clock.)
Simply, if you double tap the screen when the slide is closed and you can see the clock appear then it is working.
I hope this makes it clearer for you.
