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?

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 am fetching data from oracle data base in asp.net application. To achieve this functionality i have used Oracle.DataAccess dll . In my developement enviorment it working fine.
But once I deployed this code on IIS 6.0 it is stopped working and I checked my log and found connection not get established . Then I make sure Oracle.DataAccess.dll present in to bin folder also I try to put this dll in side GAC, but still my code is not working on deployed server.
I have two PC. In one pc(PC1) i have installed oracle express edition 10g (10.2.0.0 as far as i know). And in another(PC2) i have installed visual studio 2008 sp1. In PC2 the ASP.Net application is running. But i can not connect to the oracle database to PC1. PC1 and PC2 are connected by LAN(TCP/IP {Actually they are connected by wire and given two IP} ) But it was working perfectly while both ASP.net application and database were in the samae PC. ca
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.
