Author  Topic  clu82 Starting Member 4 Posts Posted - 2009-11-19 : 10:46:04 This is my current scenario: I have a program that currently runs as a single-user application connecting to a 2005 Express database (both on the same machine). This is what I am tasked to create: I have 3 physically separate locations that need to connect to a SQL Server 2005 Express database (Windows Server name: Server2003, database name: myDB) in real-time. Basically just your ordinary every-day multi-user program. While reading the book "Programming SQL Server 2005", I came across this section in the "SQL Server Express" section: "Databases running on a user instance are opened in single-user mode only, and multiple users cannot connect to databases running on a user instance." This seems to contradict the testing I have already completed: I created a test program that allows record creation in my test database. I ran 2 instances of this program from the same computer, and was able to create records in the test database. I could then refresh the DataGridView of each program to show the newly created records of both program instances. Is the book wrong or am I not reading something correctly? During installation of 2005 Express, I selected the "Named instance" of "SQLExpres", which is the default name provided. My other questions are: 1. Will my program be able to allow 15 users to connect to 2005 Express, all in real-time, accessing the same database, creating/updating records in that database? 2. Given the machine specs below, what would be a practical maximum user limitation? Users will mostly be viewing data, with the occasional record insert/update. 3. Does "Named instance" = "user instance"? 4. Assuming the database server is a Core2 Duo Dual-Processor with 4GB of memory and knowing the limitations of Express (1 proc, 1GB ram, 4GB database), are there any items I'm overlooking as I push forward with this project? I am assuming that I will need to enable TCP to allow the remote clients to connect over TCP/IP, using a connection similar to this: Data Source=10.94.40.33\\SQLExpress,13579;Network Library=DBMSSOCN;Initial Catalog=myDB;User ID=sa;Password=MySecurePassword_81 Thanks in advance for any and all comments, clu
