ConnectPool doesn't work as Oracle say
Hi,
Any one has ideas:
ConnectionPool *connPool = env->createConnectionPool
(poolUserName, poolPassword, connectString, 1, 5, 1);
Connection *conn1 = connPool->createConnection (username, passWord);
Connection *conn2 = connPool->createConnection (username, passWord);
Connection *conn3 = connPool->createConnection (username, passWord);
After this code was run, the connections I counted thru DBA Studio was still 1. It mean that ConnectionPool do not create conn2, conn3??
Help me please
Thanks
Real connections are created only when there is a round-trip requirement. In this case, you saw one connection because that is the minConn of the pool, and it gets created when the pool is created. The createConnection() calls create virtual connections and they get real connections mapped from the pool at the time of a round-trip and the unmapping happens as soon as the round-trip is done. If there is a need by multiple threads concurrently for doing round trips, then the pool size grows to serve all the threads concurrently.

I bought my iphone 4 in the UK and I am trying to use a sim in the UAE and it doesn't work. It says that the sim is not valid, how can I get this unlocked?
You are saying the phone is locked, but then you are saying there is no provider. The two situations cannot peacefully coexist. Contact Apple and they can tell you if the phone is locked and if locked to which provider the phone is locked. People on this board are not Apple employees and cannot get you that information.

Xdofo:show-carry-forward number-separators doesn't work in Oracle EBS 11i
I am displaying the ‘page total’ from within the footer of the xml-report by using the page total syntax ‘<xdofo:show-carry-forward name="pt" format="99G999G999D00"/>’.
Here the issue is that for report displayed in Spanish we are unable to display the Page Total in the required number format ie. The decimal separator should be ‘,’ and the group separator is ‘.’, since the Page Total is auto calculated and we are not able to save this value to any variable.
Currently Output is coming like: 12,052.00
Required output: 12.052,00
As well as I tried the below statement
<xdofo:inline-total display-condition="exceptlast" name="pt"><xdofo:show-carry-forward name="pt" format="99G999G999D00" number-separators=",."/></xdofo:inline-total>
But it doesn’t work in Oracle Applications 11i instance.
Anyone having any idea?

i got problem updating my iphone 3g. my phone doesn't work now. it says no service and can not be activated.beside that it says insert sim even it has sim. please help me.
I have just created this account to tell you that nothing would change if you restored your phone.
The first NO SIM nuisance happened just a week ago. Nothing had been done to the phone before that. I pressed HOME + POWER buttons to restart the phone and SIM card was successfully recognized as if nothing had happened. Then I had a lucky week, not reminded of this issue at all.
Today, however, the same problem keeps annoying me. I've used the same method to heal the phone but all I have done seems more like a placebo. So I tried the ultimate solution, restroing it in iTunes.
Ridicuously, the moment I finished basic setup on the newly restored phone, the same NO SIM CARD INSTALLED message poped up.
So IMO, it's not what you should do to erase and restore your phone.
Plus, I called my native carrier and they said no such problems have been submitted. And since my nano SIM card is quite new (three months old), I'm not going to replace it.
I googled this problem and found something on a Hong Kong webpage. The author of that thread points out that there is a flaw in the SIM card tray that prevents the phone from successfully recognizing SIM cards.
And I really hope Apple could probe into this issue and give official solutions other than restarting / restoring the phone like an idiot. -

Subquery for inserting doesn't work in Oracle package
I have experienced a very strange scenario while inserting data inside a Oracle package.
I have two tables:
- table "A"
Columns: "ID", "Value1", "...."
- table "A_Backup", which contains backup data for table A. It has one more column "BATCH_NUMBER" than table A
Columns: "BATCH_NUMBER", "ID", "Value1", "...."
I created following procedure in a package to backup data from table "A" to "A_Backup".
procedure proc_backup (v_id in number) is
declare
v_batch_number varchar2(20);
begin
/** generate a batch number using system date */
select 'BATCH' || to_char(sysdate, 'YYYYMMDDHH24MISS') into v_batch_number from dual;
/** insert Batch_NUMBER + data from A into A_BACKUP */
insert into A_BACKUP (select v_batch_number, id, value1, ... from A where A.id = v_id);
end proc_backup;
When I debug the procedure, it will not insert any data into A_BACKUP. Apparently, there are some data in table "A" meets criteria "A.id = v_id".
The strange thing: If I create same procedure. But this time I didn't put procedure inside the package, insert query will work.
Please help, I have spent a couple of days on this and never make it work. I also tried cursor, it doesn't work either. It seems Oracle package doesn't support "virtual table" (subquery in insert) or whatever you call it.Welcome to the forum!
Whenever you post provide your 4 digit Oracle version (result of SELECT * FROM V$VERSION).
I don't see any package or test code that calls the procedure or error messages or results from any procedure calls.
You say you have a problem with a package but don't post the package version of the code you are having a problem with.
How is anyone supposed to find a problem in code that you don't post? And when you post use \ tags as discussed in the FAQ. -
PreparedStatement.setString doesn't work with Oracle 10g.
Hi all,
I newbie question regarding the method setString of class java.sql.PreparedStatement. My process require to pass throught a file and check agaisnt a Oracle table if the product id of the given record exist in the table .
I use the SQL
select matnr from zncorart_ap where zartleg = ? and zentrleg = ?
to do that. When i try to replace the ? with the setString method it doesn't work and the query always return no row as ? is not a valid value.
Thx for your help.
