View 4 RepliesClose Oracle Connection In Program?
Aug 13, 2011In my program I got multiple spots where I open a Connection to an Oracle database, read some lines via a stored procedure which returns me a cursor, put them in an IDataReader, close the connection and go on.
Now everything works fine till the point of closing the connection. I've watched the connections opened to the database via TOAD for Oracle and I figured out, that the database seems to keep an connection opened after I said m_Connection.Close and m_Connection.Dispose.
I use Oracle.DataAccess and get an error after a short time, that there are to many connections. I debuged my session and made sure, that vb performs the close() command and it does it, but the database not.
DB/Reporting :: SQL Connection Open/close?
Dec 16, 2011SQL connections confuse me sometimes In almost every SQL related code on the internet the routine is like this;
* Open connection
* Execute SQL command
* Close connection
Is it good practice to just open a connection when the application starts and use that connection until the application closes?I know that sequential connections are required when processing more queries, but what if I need to poll a certain Table every x seconds? Isn't is better to keep that single connection open for as long as the application is running (and re-open when a failure occurs) instead of opening a new connection every x seconds?

View 1 RepliesSql Server - Long Pause Trying To Close ADO.NET Connection Object
Oct 14, 2011I am performing a simple exercise of opening an SQL Server database connection, pulling the first record of a table from a DataReader object, and then closing the object. However, I have noticed that theres bit of a delay, about 5 seconds or so, in closing the connection. However, the delay only occurs after the command object executes the specified query. I've worked in a setup like this before and don't remember there being such a long delay while closing the connection. [Code] The connection closes almost immediately. What gives? I have narrowed it down to the where the .ExecuteReader line that causes the delay in the connection close. Whats causing the delay and how do I resolve it?

In essence I am making a user friendly striped down program, that has variables that are manipulated by the end user, and the rest, referenced tables and libraries are coded.
