关于数据库连接字符串问题（第四部分连接 IBM DB2）

     IBM 的DB2数据库应用的还比较广泛，不过关于连接这一块的文章还是比较少的，所以本人就在这贴出关于DB2的数据库，连接方式，共大家学习。

Providers for IBM DB2

DB2 .NET Data Provider

Type:    .NET Framework Class Library
Usage:  IBM.Data.DB2.DB2Connection

Standard

Server=myAddress:myPortNumber;Database=myDataBase;UID=myUsername;PWD=myPassword;

The Server key value syntax is a server name / ip address and an optional port number (note the : in between).

 

Defining the connection pooling pool size

Server=myAddress:myPortNumber;Database=myDataBase;UID=myUsername;PWD=myPassword;Max Pool Size=100;Min Pool Size=10;

 

 

Disable connection pooling

Server=myAddress:myPortNumber;Database=myDataBase;UID=myUsername;PWD=myPassword; Pooling=false;

 

 

Connection pooling, time in pool

Server=myAddress:myPortNumber;Database=myDataBase;UID=myUsername;PWD=myPassword; Connection Lifetime=60;

Defines how many seconds the connection can remain idle in the pool before its removed from the pool.

 

Connection pooling, do not pool

Server=myAddress:myPortNumber;Database=myDataBase;UID=myUsername;PWD=myPassword; Connection Reset=false;

 

 

Specifying schema

Server=myAddress:myPortNumber;Database=myDataBase;UID=myUsername;PWD=myPassword; CurrentSchema=mySchema;

All unqualified SQL objects used with the current connection will be qualified with the provide schema name
