What is the maximum allowable value of “Max Pool Size” in a connection string?
Suppose this is my connection string in app.config
<add name="Name"
providerName="System.Data.SqlClient"
connectionString="Data Source=ServerName;Network Library=DBMSSOCN;Initial Catalog=DatabaseName;user=UserName;password=Password;Max Pool Size=1024;Pooling=true;"/>
What is the maximum value I can use instead of 1024? Remember it is maximum value, not default value.
There is no documented limit on Max Pool Size. There is however an exact documented limit on maximum number of concurrent connections to a single SQL Server (32767 per instance, see http://msdn.microsoft.com/en-us/library/ms143432(v=SQL.90).aspx).
A single ADO.NET pool can only go to a single instance, so maximum effective limit is therefore 32767.
