GetNameList function got called so many times
Hello.. I have a question. Could some one please answer me?
Suppose, I have two web pages. First one has only a link. If you click it, it will send you to second page, which only has h:dataTable like this...
<h:dataTable value="#{mybean.nameList}">
</h:dataTable>
getNameList() method returns the list of names. I put the system.out.println() method in the getNameList() method and found out that my getNameList() method get called more than one time for just a single page refresh.
Anyone knows why this is happening like that?
That is the nature of the beast. Each time the component needs the list, it accesses it from the EL expression. It you want to avoid doing an expensive operation multiple times, you will have to code your getter accordingly.

Type's constructor function is called as many times as there are attributes
The constructor method for object types is being called multiple times by SQL when using the constructor in an SQL insert statement. For example, if I create an object type called TEST_O, and an object table TEST_OT based on type TEST_O, and then insert into TEST_OT using the constructor:
INSERT INTO TEST_OT VALUES ( TEST_O( TEST_ID_SEQ.nextval, 'Test', USER, SYSDATE ) );
The contructor is actually called 5 times by SQL. Here's a sample type, table, type body, and anonymous PL/SQL procedure that reproduces this error:

A function in a subquery is call too many times.
Dear all,
I'm struggling to understand why a function in a subquery is called too many times.
Let me explain with an example:
create or replace function all_emp (v_deptno in number)
return varchar2
as
v_all_emp varchar2(2000);
begin
dbms_output.put_line ('function called');
for i in (select * from emp where deptno = v_deptno) loop
v_all_emp := v_all_emp || i.ename || '; ';
end loop;
return v_all_emp;
end;
-- running just the subquery, calls the function all_emp only 4 times (once for each row in table dept)
select
d.deptno,
d.dname,
all_emp(d.deptno) f_all_emp
from dept d;
-- running the whole query, using regexp to split the value of f_all_emp into separate fields, causes that function all_emp is called 28 times, thus 6 times for each row!!
select tmp.*,
regexp_substr(f_all_emp,'[^;]*',1,1) emp1,
regexp_substr(f_all_emp,'[^;]*',1,3) emp2,
regexp_substr(f_all_emp,'[^;]*',1,5) emp3,
regexp_substr(f_all_emp,'[^;]*',1,7) emp4,
regexp_substr(f_all_emp,'[^;]*',1,9) emp5,
regexp_substr(f_all_emp,'[^;]*',1,11) emp6
from
(select
d.deptno,
d.dname,
all_emp(d.deptno) f_all_emp
from dept d) tmp
;I don't understand why Oracle is calling my function 28 times in this example, 4 times should be sufficient.
Is there a way to force that the subquery is materialized first?
Little background:
Above function / query is of course a simple example.
Actually I have pretty complex function, embedding in a subquery.
The subquery is already slow (2 min to run), but when I want to split the result of the funciton in multiple (approx 20) fields it's over an hour due to above described behaviour.Optimizer merges in-line view and query results in:
select d.deptno,
d.dname,
all_emp(d.deptno) f_all_emp
regexp_substr(all_emp(d.deptno),'[^;]*',1,1) emp1,
regexp_substr(all_emp(d.deptno),'[^;]*',1,3) emp2,
regexp_substr(all_emp(d.deptno),'[^;]*',1,5) emp3,
regexp_substr(all_emp(d.deptno),'[^;]*',1,7) emp4,
regexp_substr(all_emp(d.deptno),'[^;]*',1,9) emp5,
regexp_substr(all_emp(d.deptno),'[^;]*',1,11) emp6
from dept d
/That's why function is called 28 times. We can see it from explain plan:

Dialog Box does not function when called a second time
I have created a dialog box that only seems to work once in a larger application. The box is designed to be a MatLab code debugger. My idea was to allow a user to interactively create/debug Matlab code from LabView using ActiveX automation. Anyway, I have created a test vi that uses this dialog box twice. The first time it is called it functions as expected, but the second time nothing on the front panel (of the dialog box) responds and I cannot close the window or interrupt the vi. I am using LabVIEW 7.0 on Windows 98. Please see the attached vi's. MatlabDebugger.vi is the dialog that's causing the problem. Matlabx2.vi is the sub vi that handles the ActiveX automation. Debuggertest.vi is the test v
i in which the dialog will not word a second time.
Thanks in advance for any help or suggestions.
Attachments:
Debuggertest.vi 51 KB
MatlabDebugger.vi 303 KB
Matlabx2.vi 361 KBThe problem is caused by the nested event structures; you have an event structure inside an event structure, acting on the same controls. When the main one reacts to the cancel the other one get's stuck...so on the next call the main event structure just halts due to the stuck event structure inside it. It's not obvious why this is a fault, you may be able to spot it now that you're on the track though.

Why is tableView titleForFooterInSection is called so many times?
Hi,
I have a table and I am noticing that for every new row which shows up during scrolling operation (one call to
tableView cellForRowAtIndexPath
there are 27 (!!!) calls to

Why so many?
While application seems to work fine, I am concern about performance.

Place the iOS device in Recovery Mode and then connect to your computer and restore via iTunes. The iPod will be erased.
iOS: Forgot passcode or device disabled
If recovery mode does not work try DFU mode.

For how to restore:
iTunes: Restoring iOS software
To restore from backup see:
iOS: Back up and restore your iOS device with iCloud or iTunes
If you restore from iCloud backup the apps will be automatically downloaded. If you restore from iTunes backup the apps and music have to be in the iTunes library since synced media like apps and music are not included in the backup of the iOS device that iTunes makes.
You can redownload most iTunes purchases by:
Downloading past purchases from the App Store, iBookstore, and iTunes Store
If problem what happens or does not happen and when in the instructions? When you successfully get the iPod in recovery mode and connect to computer iTunes should say it found an iPod in recovery mode. -
NOKIA6210 NAVIGATOR:HOW MANY TIMES HAS BEEN RECEIV...
Hello
Is urgent, please.
In other nokia models I could see - at received calls- how many times a single number( the same number) has called. for example:le´ts suppose the number 123( a friend of you) called you 3 times yesterday. How could you see these 3 calls with their respective hours with the 6210 navigator?
Thank you very much for your help.You can see that in the log application.
Not the call log that you get by pressing the green key but the full log accessible through the phone's menus.

Can I CALL FUNCTION 'SPBT_INITIALIZE' many times ?
Hi ABAP Expert,
I need your advise whether is recommended to calling FUNCTION 'SPBT_INITIALIZE' to get updated information regarding available background process for parallel processing in ABAP.
Because if i just call this program 1 time at the beginning and the report running quite long, the information is not updated anymore.
Please advise.
Thank you in advance
Fernand.Hi
what you can do is create form and perform
write your code for that FM in Form part and use perform wherever in your program you want to use.
whenever the perform will be triggered it will go to the form part where you are calling the FM.
I hope this way you can use it multiple time without calling it every time from pattern.
But I am not sure whether it is a good approach or not?
thanks

My iphone hangs any time.I see a call coming but i cannot attend. My call drops anytime and i cant even end the call.The settings page doesnt respond many times.I have given the phone to Apple care , they update the software and return it back to me.IT WORKS FINE FOR 3-4 DAYS AGAIN THE SAME. Its under warranty and i am disappointed with the Apple product and service
If you used your backup to restore the data after it got returned, set it up as new device and don't use the backup data afterwards. It seems that some data inside the backup are corrupt. Follow this article and set up the account info and other setting manually after that:
Use iTunes to restore your iOS device to factory settings - Apple Support -
Since I upgraded to IOS 7.0.2, many times I am unable to answer the calls. Then I have to switch off and on to answer the calls. I checked with my three friends who updated and they are also facing same problem. Kindly let me know the solution.
Since other millions of people updated and do not have that problem - it means one of two.
1.Your friends lied to you and do not have that problem and in that case only your installation of ios7 got corrupted and you need to restore your phone.
2.Your friends didn't lie to you and all 4 of you need to restore phones (that way reinstalling ios 7 properly)
here are instructions for restore and you may have to backup before restore.

Log in function locking users that introduce a wrong password many times
I need to create a log in function that validates the username and the password and blocking or locking users that introduce a wrong password many times in a specific period of time. The idea is when it happens, the user has to call the administrator of the system to be unlock.
Thanks for your help.
Edited by: user13486053 on Jan 6, 2011 6:47 AMIf your are using custom authentication,
<li>There is an bultin table which contains the login acess attempts of users: APEX_USER_ACCESS_LOG , You might be interested in the columns APPLICATION,LOGINNAME,ACCESS_DATE,AUTHENTICATION_RESULT_ .
However, inorder to set the authentication_result column(therby identify failed attempts), you would have to call the APEX_UTIL.SET_AUTHENTICATION_RESULT function in your authentication function. Otherwise it would be null both for success and failure cases.
Try this, for finding failure count in last <failure check period>
select count(1)
from APEX_USER_ACCESS_LOG
where application = [APP_ID]
and login_name = [username] --case sensitive
AND authentication_result = [failure status]
and SYSDATE - access_date <= [failure check period]For locking out you would have to flag some column in your custom table and show the user some message in the login page
If you want to use your own table, here's an approach
Have a table for logging user's login status and time.
In ur authentication function, you can write to this table everytime a login fails if its succesful u can remove previous 'failure' entries and create a 'success' entry.
Use count the number of failures within that time period u want say 24 hrs (SELECT count(1) from <table name> where SYSDATE - <DATE column> LESS THAN 1 Day).
If the count is more than ur required no: flag the users record as locked(have some column updated)
In your login page, have some conditional region with some text which says the user's account is locked out(the condition can be locked column status of the user who tried to login, use the username page item for identifying the user)Hope it helps -

Hello guys..!! I have got my new iphone 4 2 days ago.The same day it got a problem of auto restart in every 1, to 2 minutes. I updated and restored it many times...but of no use... can any one help me how to solve this problem..!!
Go to Settings/General/Reset - Erase all content and settings. the connecto to iTunes and restore as a New phone. Do not restore any backup. If the problem persists you have a hardware problem. Take it to Apple for exchange.
This assumes that the phone is not hacked or jailbroken. If it is you will have to go elsewhere on the internet for help. -
How many times do you have to tell the call centre...
I have had excellent service from BT with a line speed of some 7.5 to almost 9 meg download and around 1 meg upload.
Recently my download speed slowed dramatically to 400k BUT the upload speed stayed the same.
When I could no longer use iplayer Utube or any TV on demand I tried to call the fault reporting.
First on Friday I spent almost an hour trying everything wireless change channels - Socket unplug the house and go to the main ( carrying my PC and router up two flights of stairs)
I eventually was put to a supervisor who said he understood that its a problem with the exchange and promised to do something.
Friday passed along with Saturday Sunday and Monday, repeated speed tests show aprox 400K download both on BT system and also on external speed checks. Interogating my router for DSL speed also confirmed upload 1 meg and download 400k.
Tuesday - rang back and had all the same questions are you on wireless? Expecting this I had already changed to wired.
Next question back to main sockets vice extensions, again, Having explained the supervisor from Friday already checked this and was going to get it fixed - I had to refuse to move my setup upstairs again since I had already done it twice on Friday.
Has there been a storm? of course UK has storms BUT I tried to explain that if the line is noisy or wet both uplink and downlink normally fade together.
I asked what progress had been made ? They did not seem to have any update and limited information - SURELY BT take notes and put them on the system?
Eventually I had another supervisor - after explaining everything he conceeded that the first supervisor on Friday did nothing. He then again asked to recheck the line and for the 4th time got the same results as me 400k down 1 meg up. He also tried to ask about wireless which I had eliminated and router - OH mine is a belkin not BT hub so that caused consternation. He after what seemed ages went away to test the line again and the phone of course dropped out as it will if your testing. He never rang back either.
In order not to have more of the same I connected the BT home hub supplied by BT and set it up and tested the speed - Guess what the speed was identical on the BT hub as my Belkin but at least they cant blame that.
Being totally frustrated I tried again and got another operator - and yes they wanted mainly to talk about my wireless being the problem I quickly explained its wired which kind of threw them - yes your right the main socket issue came up again but seriously Im not lugging all that kit upstairs again when Ive already done it. The inevitable test the line took place and yet again for the 4th time the results were identical - max 400k download ( 1 meg up).
After having to become very forceful this person agreed that OK I had done all the tests ( several times). When I asked what was on the system for the fault and who dealt with it last time - nothing.
They agreed to send me an email which I have got and also this time to reset my profile? What profile and why was it not set before? I have now been told my speed will increase over 48 hours - currently its not yet changed!
I expect that I will probably have to go through all this again, why dont they write down whats been done so you dont have to what a waste of all our times.
Well as you may tell Im not terribly happy with this and dont have confidence that it will get fixed - which means its probably going to be bad over christmas - I dont normally write to furums and having been an engineer all my life and pretty good with PC's I found the whole experience very frustrating. Anyone know what changing the profile may do and does it really take 48 hours?
Solved!
Go to Solution.Latest no speed change after 24 hours not one tiny bit - so much for it increasing gradually to the old maximum.
Stats
BT speed check gave me Downstream 468 IP Profile 506
Upstream 929 IP Profile 1135.
Much the same as I have got for the past week and also get on either router and still get after a supposed profile reset.
Checks on mybroadbandspeed.co.uk which I have been keeping for 12 months show its down from more than 7 meg to 400k.
Anyone know why the DSL link shows a better uplink than downlink - Faulty DSLAM ?

How many times can i call the start()
Hi All:
I would like to know how many time you can actually call the start(),
cuz my app is doing some really strange things,
here is a fragament of my code:
private void spawnThreads()
ListIterator it = _vWorker.listIterator();
while ( it.hasNext() ) {
ClientWorker client_worker = (ClientWorker) it.next();
client_worker.start();
ClientWorker is another Thread, and in the run() of the ClientWorker, I have
public void run() {
Runtime rt = Runtime.getRuntime();
try {
// Start the timer
Process child = rt.exec(_fileName);
// gobble any error or output streams
StreamGobbler errorGobbler = new
StreamGobbler(child.getErrorStream(), "ERROR");
StreamGobbler outputGobbler = new
StreamGobbler(child.getInputStream(), "OUTPUT");
errorGobbler.start();
outputGobbler.start();
child.waitFor();
} catch (IOException e) {
System.err.println("IOException starting process!");
} catch (InterruptedException e) {
System.err.println("Interrupted waiting for process!");
I have a couple of cmd files to execute, so This spawnThreads() will be called a couple of times,and the funny thing is , it will execute the first cmd files, and that is it, it won't execute the 2nd or the 3rd cmd files, it will start the thread, but then the run()won't actually gets invoked,,,so I am just wondering if anyone of you has encountered this problem, perhaps you could lend me some insight on this?
thanks,Yes, you can run the start() of a Thread more than once,
here is my Test App,
public static void main(String[] args) throws Exception {
Vector vec = new Vector();
for (int i=0;i<4;i++){
ClientThread ct = new ClientThread();
vec.add(ct);
ListIterator it = vec.listIterator();
while(it.hasNext()){
ClientThread ct = (ClientThread)it.next();
ct.start();
and as you have already guessed it the run() of ClientThread simply does system.out.println()
and here is the output
run started
run started
run started
run started
so..yeah..I don't really have any idea what is happening to my app and why it is not executing any cmd files after executing the very first cmd file
Maybe you are looking for

Stunned at lack of Support from Verizon
A little over a year ago, I left Sprint for Verizon because everyone told me how much better it was. So far, the phone service has not been any better at all; certainly not worth the extra money I pay Verizon. Today, Verizon attempted to deliver the
