We have 2 servers (UNIX) in our Organization. First is a Database Server and the second one, Application Server. We created a SQL*Loader Concurrent Program Executable. We have also entered the path in Concurrent Program. The path is available in both Database Server and Application Server.
The query is,
When we run Oracle EBS application, will it search the file in the Application Server or the Database Server
Suppose if it is searching in the Application Server, is there a way to direct Oracle EBS application to search the Database Server instead of the Application Server? Can such setting be done in Concurrent Program?

I'm about to deploy an ASP.NET web application for testing in production. Essentially, this is just a table that is linked to a SQL Server table/view that is obviously dynamic when the data in the tables are updated.
I have a hosting plan with a site that I'll be pushing the files to, which includes a SQL Server database in the hosting plan. I also host a SQL Server instance on the network.
My question is, what is the standard way of dealing with SQL Server in this deployment? I think I have the options below, but as someone who has only ever developed applications offline, this is new to me, so please excuse my novice ignorance.
Have the application connect via IP address in the connection string to my SQL Server instance, as specifying the server name (SQLDEVSRV01 for example) won't be on the "network" when it's sitting in the site's FTP. Am I to assume my connection string will only work on the network, and once deployed to a website, will cease to function unless connecting via TCP/IP?
Host the server on the web in the same site host location. So upload the site files to my website host and setup the SQL server there. Would I be able to just specify the Server name (SQLDEVSRV01 for example) in the connection string there, as whilst it wouldn't work in development as it wouldn't be on the same network, it would then work once deployed on the web?
Embed a SQL Server instance within the app using localdB or something similar to hold the background data. If this is the case, can the data be accessed from the backend, either using SSMS or some other method?
Essentially, my aim here is to have the web app retrieve the data live from a view/table hosted in SQL server, where the backend data can be amended, manipulated and updated independently of the app, so the app can just pull the data when refreshed.
The standard way of doing this is to deploy your database to the hosting providers SQL Server instance and then connect your app to it using a connection string with their details. As it is normally a shared instance you do not have to normally worry about having the SQL instance machine patched etc.
Personally I would not be installing SQL Server myself unless I decided there was benefit to having an instance I wanted the control over nor would I be changing the structure or implementation of my application to suit a hosting providers setup.
I have one server installed locally and other is company,s live server. I have an application installed on local machine, so whenever I run my application data on both SQL Server instances (local and live) should sync to keep same database on both servers how this can be done live database in cloud server with public ip and local databases are in my local system. I would be happy if anyone could provide sample format for this using asp.net C#
Why don't you use SQL Server Replication.
http://sqlknowledge.com/2014/04/sql-2014-express-edition-limitations/
On this website, the author says SQL Server express 2014's Max instance per server is 50. Does it mean only 50 users can connect to the server, or access the server at the same time?
So, if I'm building a data-driven website(using ASP.NET C#) that inserts/retrieves data from SQL Server 2014 express, only 50 users can log onto my website at the same time??
Thanks
It means that the maximum number of SQL server installations (instances) on a single server is 50. Typically, you will only use 1 instance for an application.
An Instance of a SQL Server on a PC/Computer/Server means when you inserted the CD and installed SQL Server (Application) on the machine.
Each time you Install SQL Server (Application) on a PC it installs an INSTANCE of SQL Server.
Each time you install an Instance you have to give it a Name. It will be the Instance name.
When you are installing SQL Server it gives you the option of giving it a Name or pick the Default name for the installation.
If it is a Default instance you will connect to it by using only the MachineName.
If it is a Named Instance you will connect it to using the MachineName\InstanceName.
There can be only ONE Default Instance of SQL Server on a machine and Multiple Named instances (in Sql Server 2014 case 49) and obviously one named instance.
The maximum number of user to connect to SQL Server can be checked by looking at
In Object Explorer, right-click a server and click Properties.
Click the Connections node.
Under Connections, in the Max number of concurrent connections
Important Note
SQL Server being a resource hungry monster, it is best to keep only one instance of sql server on a machine. Otherwise your one instance of SQL Server can starve other instances of resources (memory, CPU) .
Basically to start with is it even possible to have a form that runs in asp.net and have it write data to a mysql database on a remote Apache web server? If so any pointers!? Not even sure really where to start researching it!
Yes and no...
form that runs in asp.net
Forms do not run "in" ASP.NET.
You can generate an HTML form using ASP.NET. You can submit form data to a webserver that uses ASP.NET to process the data.
write data to a mysql database
ASP.NET has database bindings that can talk with MySQL
mysql database on a remote
MySQL can listen on network interfaces so clients can connect over the network instead of using local sockets.
mysql database on a remote Apache web server
MySQL can't run on an Apache server. Apache is not an operating system.
MySQL can run on a server that is also running Apache, but with the above set up, Apache would be irrelevant.
Apache could be used to run a web service (e.g. written in Perl, Python or PHP) that connects to and queries a local MySQL server. ASP.NET could make HTTP requests to that webservice.
ASP.NET could be used to generate a form with an action that points to a URL that is handled by an Apache server.
Yes, you can write to a database anywhere in the world so long as you can:
Connect
Authenticate
Communicate (in a similar language)
You just need a connection to the database with valid credentials. You can talk to mySQL from .NET using the mySQL client.
In "theory" it's no different from a web server talking to a separate database server in the same building so long as the above three points are facilitated.
I'm trying to place a .mdf database on a Computer A and access it simultaneously on Computer B but I'm having an error that says I cannot access the mdf file because it's being used by another process.
The setup is, the database is hosted on a Public folder in Computer A. I have Visual Studio running on both computers, and Computer B accesses the database on Computer A.
Computer A Connection path string:
C:\Users\Public\database.mdf
Computer B Connection path string:
\192.168.254.8\Public\database.mdf
Is there some sort of setting that I do not know of to enable multiple access on a db? Or this is not possible?
EDIT:
Let me rephrase my question, sorry.
There are two computers connected via a network, and I want to access one Visual Studio solution/project website. I wanted to do this as a demonstration, is it possible?
You should have an instance of SQL Server (even express) running on the host machine.
All requests from the clients should use the standard mechanisms for connecting to that server instance. In other words, they won't run their own copy of SQL Server, instead they will connect to the instance running on the host machine.
Simultaneous or direct access to Database files under any DBMS control either a very bad practice or simply impossible.
Use proper DBMS tools to access the data.
And yes - its possible to access Web site project for demo.
Install SQL Server on the host machine (the one that you want to keep your database on).
Then in Visual Studio, use the "Server Explorer" to locate the remote instance of the database. From there, you can utilize the remote instance of SQL Server in your connection string, thus allowing you to connect multiple computers to a single database.
Using two instances of SQL Server to connect to the single .mdf file is a very bad practice.
Instead of specifying the MDF file in your connection string (which, I believe, uses a form of User Instancing), you should use SQL Server Management Studio (SSMS) to attach the MDF. Then connect to SQL Server, rather than to the MDF.
You may need to move the MDF and LDF files to a place where the SQL Server identity can access them, rather than keeping them in your VS project.
Most projects keep scripts to create the DB in their VS project, but not the binary MDF itself.
When you deploy, the process is similar: use SSMS to attach the MDF on your server.
Yes, If 2 or More Computers are connected by networks like LAN You can access the Database Database1.mdf (say) from another SQL Server by entering its user name / Password /by Visual studio connection.
Disadvantages:
If more than 7~8 systems are accessing same Database same time System response slows down and Hangs up or may result error like connection pool exceeded or Device not responding..
In Big Companies they use Huge Multi-core & Multi-Processer based sever which will respond faster.
Overcome: while writing Applications Use Connection Open and Close Particularly while executing the SQL queries in other time it should be closed.
Best Programer uses Transaction instead of using normal methods. Transaction Makes Every User Access Database With valid and successful Execution of queries. These Queries (Transaction Queries) mainly executes on client machine and later updates the same over Main server when it got Time slot for it(synchronize).
