這是俺所關注的內容：

Using Connection Pooling

The connection pooling service will create a new pool if it can't find any existing pool that exactly match the new connections connection string properties. If there is a matching pool a connection will be recycled from that pool.

Data Source=myOracleDB;User Id=myUsername;Password=myPassword;Min Pool Size=10;Connection Lifetime=120;Connection Timeout=60;Incr Pool Size=5;Decr Pool Size=2;

實際中有看到這種寫法的：
.NET與ORACLE的連接方式
（OracleConnection(.NET)）採用共享池鏈接，連接字符串。（寫在web.config）
<add key="strConn" value="User ID=fjdms;Data Source=fjdms_lyj;Password=XXXX;Max Pool Size=1000;pooling=true;" />

從ORACLE網站上看到的連接字符串《通過 Visual Studio 調試 Oracle PL/SQL 》：http://www.oracle.com/technology/global/cn/obe/odt/debugging/debugging.htm

string constr = "User Id=hr; Password=hr; Data Source=ORCL; enlist=false; pooling=false";
