Using the connection for easy connection descriptor
HelloI'm new here. We change a MySQL to Oracle server. I need help for my NET access to Oracle application. I tried to connect to the server, but the connection failed. Here my code for MySQL (ODBC connection)
' Connection MYODBC 3.51 string
Dim MyConString As String = "DRIVER = {MySQL ODBC 3.51 Driver};" & _
"SERVER = 10.177.224.53;" & _
"DATABASE = result;" & _
"USER = 1234;" & _
"PASSWORD = xxx;" & _
"OPTION = 2;"
Dim adapter as OdbcDataAdapter
Try
adapter = New OdbcDataAdapter (strSQL, MyConString)
adapter. MissingMappingAction = MissingMappingAction.Passthrough
adapter. MissingSchemaAction = MissingSchemaAction.AddWithKey
This method works great. Can eveyone show me how to make an easy connection with ODP.NET using a simple connection string wiithout tnsnames.ora according to this document:
Source = (DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP) (HOST = MyHost)(PORT=MyPort))) (CONNECT_DATA = (SERVER = DEDICATED) (SERVICE_NAME = MyOracleSID))) of data; User Id = myUsername; Password = myPassword;
?? where is the DATA base (= 'result')
I have the b28844.pdf document and copy the following code:
Conn. ConnectionString = "name of user =" + userID.Text & _
"; Password ="+ password. Text & _
« ; Data Source ="+ dataSource.Text
Conn. Open()
What is the content of dataSource.Text?

Connection failed how? What was the exact error message?
"DATABASE = result;" & _
Oracle database! = MySQL.
In Oracle, you have a database and it can contain several diagrams (which are mapped 1:1 for the connection of the user). The concept of a "database" is different from the terminology of MySQL.
The 'default' diagram depends on user name used in connection for example user = TEST involves TEST schema objects.
If you want to access several patterns, specify an identifier pointed as in select * from schemaname.objectname. (assuming that the user has the necessary permissions).

Simple (Easy connect) connection string format is:
HostName: Port / service
data source for example = MyHost:MyPort / MyOracleService (not the SID instead since 8i Service registered listener name services - see lsnrctl stat command output side Server)

I get this error when you try to create a data store for Oracle database of the Disqualification.
ORA-12505, TNS: Listener does not currently of SID in the connection descriptor (code: 2 011)
I am able to connect to this database by using the same credentials through SQL, but the Disqualification, I'm not. Do I need to do anything in linux server before the implementation of Oracle data warehouses?
Thank you

There are a number of ways.
1 use a JNDI connection configured in WebLogic and select by name
2. use the LDAP connection or TNS - see http://docs.oracle.com/middleware/1213/edq/DQEXT/config_dbase.htm#DQEXT202
3. Add an oracle.xml file in [local disqualification home] / dbconnectors with the following content. This will allow you to select the service name in the standard Oracle data store wizard:

When connecting to even via the remote desktop connection it works fine, but when a second (another) user tries to connect using the connection to remote, a message "select a user to disconnect so you can connect. The names of the 2 users are displayed the first is the name of the administrator of the local server and the second is the remote desktop user who was first. We need at least 3 to 4 remote desktop both users to be connected. Please advice

Can I use the Connect By operator to generate a set?
Connect By operator is a way to manage hierarchical models implemented through tables.
Is it possible to use generate games as in CTE (or of the recursive subquery factoring)?
Hello

Sorry, I should have made myself clearer...
Connect By using hierarchical tables: we take such a table and find all the managers of a worker or all ordered sub of a Manager, etc..
The CTE has also the possibility to take a select degenerate double and create from it a set of all numbers up to...
My question is if there is a way to use the connection by to create a game of duel, or it is impossible, and it works with hierarchical tables?
It is obvious that the CTE can all Connect By possible.
but it is also true to the other side?
Another question - what year was published the first version of Oracle that supports CTES?
Thank you very much!
CONNECT BY a designed for contiguity-model trees, as you described. In my previous post, I said that this was an area where CONNECT BY might be better than a WITH recursive clause. If I gave the impression that CONNECT BY is not good for anything else, I apologize. It is very useful for other things and better than recursive WITH many clauses.
For example, CONNECT BY can be used to generate a 'meter' table, for example, to get a 10 ranks, contain integers from 1 to 10:
SELECT LEVEL AS n
OF the double
CONNECT BY LEVEL<=>=>
It's actally a common use of CONNECT BY, and it is very effective.
I don't think that CONNECT BY can do everything that can make a WITH recursive clause. Perhaps CONNECT BY as well as MODEL or some XML functions, can do that a WITH recursive clause can do, but it could be much more difficult and far less effective.
WITH the clauses were new in Oracle 9.1, released in 2001.
Recursif WITH clauses were new in Oracle 11.2, released in 2009.
I think it's interesteing CONNECT BY has been integrated into Oracle 2, released in 1979.

I do my job to the computer on a MAC book PRO. I want to create a document using Pages and then convert the document to PDF and send a group email. I want to send the PDF using the pdf for each receiver icon must click the icon to open the document. My problem is the document does not show the icon, but rather the document is already open. I spoke with 2 Apple. 'Experts' care and can help me. Can someone tell me what to do?
It's a question of how the recipients e-mail programs deal with attachments. Many e-mail programs will open all the files they can handle, including files jpg and PDF, by default, and if the recipient has not changed that there is nothing you can do about it. The only solution is to the compress first, then it will be delivered as an attachment, allowing the recipient to decompress and open it.

What is a good way to use the queues for the model of consumers/producers?
Hi all
I am following the model of consumers/producers to use the queue to synchronize the following process: the producer is a loop to produce a number N, I will put each number generated in a table and after each 5 numbers generated, I put the table in the queue and pass it on to the consumer. I have to wait the use by consumers of the data and it will then remove the item from queue so that producers will have the chance to produce another 5 numbers. As I put the maximum size of the queue one, I expect that the producer and the consumer turns to produce / consume all five numbers and the opportunity to another. Here is my code
When the checkbox is false, the code will be
For the first 5 numbers, product will generate every thing right and put it in the table, and it's going to pass the array to the quere so that the consumer will have the chance to loop through the table. I except the procude loop will continue only when the queue is available (i.e. all items are deleted), but it seems that once the consumer starts the loop loop of the product will continue (if the indicator x + 1 and x 2 will be changed to numbers). But this isn't what I want, I know there must be something wrong, but I can't say it is.

As you say in 1, sequency structure to enforce the order of execution, that's why I put it here, in this example, the simple question, I replace the complete code with increase in the number, in the real case, the first markers + 1 and + 2 must be performed in this order.
Mikeporter says:
1. get rid of all the structures of the sequence. None of them are nothing but apply a work order which would have been the same without them.So even if you delete the sequence structure, there will be a fixed & defined order and it is because LabVIEW follows the MODEL of FLOW OF DATA.
Data flow model (more precisely in the context of LabVIEW): a block diagram node runs when it receives the required inputs. When a node is running, it produces output data and transmits data to the next node in the path of the data stream. The flow of data on the nodes determines the order of execution of the VIs and functions on the block diagram (click here for reference).
Now in your code, just remove the sequence structure will not make you order will be going to stay the same, but you need to do some very minor changes (as thread of the error in loop, before that he go to the node "Élément Dequeue").
Come to the main point: it's a good way to use the queue for the consumer/pmodel that?
The model you are using (and qualifying as consumer/pmodel) is much too deviated from the original consumer/pmodel which model.dragondriver wrote:
For the second, Yes, it's my fault for delete, though. I'm actually the example of model of producer/consumer design pattern, but I do not pay attention to the while loop in the part of the consumer.
While loops (two producers & consumers) are the essential part of this architecture and cannot be deleted. You can start your code using standard model.

My CS5 Illustrator (just updated) guard smoking when I either try to re - create a link, scroll through fonts, use the pipette for the selection of the color of police/or save to a new folder outside of the previously used. Even when I choose to close, he said that it "unexpected." Really irritating - ideas?
Your options are:
-try to make it work (could take a few hours and may does not always work)
-get the CS6 (has problems as well, but works a little better)
-get CC
-install a virtual machine with an older system (10.6 or 10.8)
-Check if your Mac is not as new as you think and you can still run Yosemite (also has problems, but perhaps not as much)
