View 2 RepliesI have to automate one database process in .Net web applicaiton which uses Oracle 11g Database as Backend.
I need to know two things:
(1) How to check space on Oracle database server? I need space on server and not in the Database itself. My process creates few tables so I want to make sure that we have sufficient space before the process starts.
(2) Also I need to create script to backup Indexes and Triggers on the table so that I can recreate them after data transfer process is completed. Any idea how to create script form c# code?

I'm a little confused as to what is causing the following error is a very simple application: System.ArgumentException: An OLE DB Provider was not specified in the ConnectionString. An example would be, 'Provider=SQLOLEDB The code-behind has this:
OleDbConnection conn = new
OleDbConnection(ConfigurationManager.ConnectionStrings["db_conn_qa"].ConnectionString);
In the Web.Config, the following is present (note the Provider is clearly there):
<configuration>
<appSettings/>
<connectionStrings>
<add name="db_conn_qa" connectionString="Data Source=xx;Persist Security Info=True;User ID=xx;Password=xx;Unicode=True"

We have an Oracle 11g database with two nodes. On occasion, one of the nodes goes down and for some reason one of my applications starts throwing this exception:
Error Message: System.Web.Services.Protocols.SoapException: Server was unable to process request. ---> System.InvalidOperationException: Timeout expired. The timeout period elapsed prior to obtaining a connection from the pool. This may have occurred because
all pooled connections were in use and max pool size was reached.

Out IT group says that this is a program bug because the failover isn't working, but I am thinking that this is a function of the database.What is the cause, and if it is an application bug, what can be done code-wise to fix this problem? The connection string doesn't specify a particular node.

View 1 RepliesWe are building an ASP.NET application with C#.net language and Oracle 9i database. Here we installed Oracle 9i client software on our PCs.We never worked on Oracle 9i database. It's the first time.We are planning to build stored procedures in Oracle database and call them from our ASP.NET application. Does working with Oracle stored procedures and ASP.NET is similar to that of working with MS SQL Server stored procedures and ASP.NET?
View 1 RepliesI have few questions regarding MySql database.
First one will be: I've installed MySql, Query broswer, and ODBC connector (not sure what this one does. Can anyone explain?)
Now, when im dragging a new DataGridView into the form, and try to connect it to a MySql database, i can't seem to find MySql in the databases list... why is that?
Second question, assuming everything works fine, how can i upload the database to a server and use it there?
I can think of two problems trying to do this : (1) Im not sure where my Database files are stored at... (for some reason, they are not found in MySql/Data... this folder is completly absent)
(2) While working with ACCESS, all i had to do is to point the .aspx page that did the connecting to the location of the .mdb file, but now, each time i want to reach my database, i need to send the page to the server (localhost). How will i create a connection to my database, when its on another server, in the code page ? (small code example would be nice).
protected void Button3_Click(object sender, EventArgs e)
{
//Create a connection to the database
MySqlConnection conn = new MySqlConnection("Database=kid07025;Data Source=195.178.228.254;User Id=kid07025;Password=********");
//open the connection
conn.Open();
//MySQL Query which updates the row where Anvandarnamn = Anvandarnamn (recieved from a cookie)
MySqlCommand cmd = new MySqlCommand("UPDATE personer SET Information=?Information,Fnamn=?Fnamn,Enamn=?Enamn,Personnr=?Personnr,Adress=?Adress,Postnr=?Postnr,Ort=?Ort WHERE Anvandarnamn=?Anvandarnamn", conn);
// Update with new text
cmd.Parameters.AddWithValue("?Anvandarnamn", Request.Cookies["Anvandarnamn"].Value);
cmd.Parameters.AddWithValue("?Information", TextBox1.Text);
cmd.Parameters.AddWithValue("?Fnamn", TextBox2.Text);
cmd.Parameters.AddWithValue("?Enamn", TextBox3.Text);
cmd.Parameters.AddWithValue("?Personnr",TextBox4.Text);
cmd.Parameters.AddWithValue("?Adress", TextBox5.Text);
cmd.Parameters.AddWithValue("?Postnr", TextBox6.Text);
cmd.Parameters.AddWithValue("?Ort", TextBox7.Text);
cmd.ExecuteReader();
conn.Close();
RefreshProfile();
}
I don't know what I am doing wrong here, but the database doesn't get updated when I press the button.
I use VS 2010, ASP.NET
I've developed a web app in Visual Studio 2008 using ASP.NET which connects to an Oracle database and a separate SQL Server 2005 database in the same application.
I want to convert this application to use SQL Server only. I have copied the Oracle tables that I need to SQL Server and am in the process of converting the SQL queries from Oracle format to SQL Server format.
I have also modified all the Connection Strings in web.config to point to the SQL Server database now and not the Oracle one.
However I have come across a problem. The TableAdapters are configured to use the OracleClient in the declarations code behind the scenes, i.e. it is "hard coded". But this causes problems of course while modifying/saving queries, because I don't want any trace of Oracle in my new web app.
The only thing I can think of is to delete all my TableAdapters and re-create them all.
I need to transfer SQL Server databse to Oracle database.
