It is passed in code to an underlying driver or provider in order to initiate the connection. Whilst commonly used for a database connection, the data source could also be a spreadsheet or text file.
When connection pool configurations exceed these limits, issues such as rejected connections, throttling, or degraded performance can occur. Depending on how database limits are applied, overprovisioned connection pools can create significant resource contention as the server struggles to manage excessive simultaneous connections.
The term often overlaps with "connection string". Most systems do not make a distinction between DSNs or connection strings and the term can often be used interchangeably. [1] DSN attributes may include, but are not limited to: [2] the name of the data source; the location of the data source; the name of a database driver which can access the ...
