Databases :: Oracle Database Failover Not Working With Pooled Connections?
Feb 22, 2010
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.
at System.Data.OracleClient.OracleConnectionPoolManager.GetPooledConnection(String encryptedConnectionString, OracleConnectionString options, OracleConnection owningObject, Boolean& isInTransaction)
at System.Data.OracleClient.OracleConnection.OpenInternal(OracleConnectionString parsedConnectionString, Object transact)
at System.Data.OracleClient.OracleConnection.Open()
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.

I'm implementing a Google like search box in my asp.net application. Each keypress in the box sends an Ajax request to IIS webmethod that queries the txt and return matches - works pretty cool. However, on loading up activity (e.g. 300 users), I'm getting errors that my 100 Pooled connections are used up. Now I'm rethinking that perhaps opening/closing a db connection on each keystroke may be too much. How would one architect this differently, or insure that the connections are reclaimed really fast. I'm have the 'using' construct for connections to insure it is closed. The concern is GC may not be reclaiming them fast enough?
How would google handle such a large open/close cycle.

I have an application, which connects to a Oracle 10g R2 database, but what it is doing is opening lots and lots of connections and is not disposing them.
My application is using the MVC model, and I have Database Connection Class, which on unload of the page calls my dispose method, which consists the dispose and close commands. Further, on model control, on each of methods requesting data from the database, I am calling the close method on Oracle Data Reader.

Recently I bumped a problem with an asp.net application where seemingly random errors were thrown, although they were all related to the use of a connection object. Coming from Classic ASP, I wrote my pages by creating a connection object at the top of the page, and using that connection throughout the page. The connection object was opened whenever something had to be done with the database and closed immediately after.
Connectionstring:
"Data Source=<server>;Initial Catalog=<catalog>;Integrated Security=false;user=<user>;password=<password>;Pooling=False;"
So pooling=false.

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"
providerName="System.Data.OracleClient" />
</connectionStrings>
<system.web>

I 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 have a project using vb.net with mySql and mySql.Data.dll as a link to the database. Now when I test my website from local computer and with live server connection string all works fine. The thing is, when I upload my files to the server, it gives me an error Object reference not set to an instance of an object.I have copied the mySql.data.dll file to the bin folder of my domain and the query that gives the error is a basic insert statement that works from the local machine to the live database.

I need to find a way to connect to the remote Oracle server without a DSN. There are some practical problem for accessing the server using a DSN. I need a way to connect to Oracle server like I connect to SQL Server etc. For example, in SQL server, I can connect directly with server using Servername (IP adress) + Username + Password + DB Name. Any way to connect to the Oracle server like in SQL Server we do ??
