What is maximum allowable value of “Max Pool Size”

Question

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.

Answer 1

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.

Answer 2

You may check with DBA connection limit set in database server

Answer 3

As far as I know - 32767 This is the limit of Sql Server, not .NET
