verify DB connectivity

P: n/a
I'm doing some error handling in my app, and I want to add something for the
db connectiion. Is there a way to check to verify the db is up and running
before I do anything with my app?

example: the user logs in, but on the login page is there a way to either
ping the db or something to verify the database is up and running prior to
the user trying to log into the application?

Try to open a connection, using a Try/Catch block. If no errors occur,
you're good.

I just flew in from Chicago with
a man with a wooden leg named Smith
who shot an elephant in my pajamas.
So I bit him.

Hi Mike,

As Kevin has mentioned, you can simply try connecting to the database(or
execute a simply query) to detect the database server availability. Also,
generally, we can specify a connectionTimeout period in the
connectionstring so that the connection estabhlish attemp will timeout in a
certain period .e.g.

======================
static private string GetConnectionString()
{

return "Data Source=(local);Initial Catalog=AdventureWorks;"
+ "Integrated Security=SSPI;Connection Timeout=30";
}

=====================.

Thus, you can control the connection establish attempt within a specific
timespan and determine whether the server is currently available.

Please feel free to post here if you have any other questions or ideas on
this.
Sincerely,

Steven Cheng
