是否清除devart中的连接池

Question

我有一个Windows服务应用程序，它每分钟连接一次数据库。有时我会得到这个错误：

ORA-2010:ORA-06508:PL/SQL:找不到正在调用的程序单元

解决方案是在plsql中关闭并重新连接数据库，但我想在应用程序端这样做。

所以我需要禁用所有连接池，并尝试重新连接数据库。如何使用devart完成此操作？

这是我的连接

this.ConnectMode = OracleConnectMode.Default;
this.Direct = true;
this.Close();
this.Server = ConfigurationManager.AppSettings["db_hostname"];
this.Port = Convert.ToInt32(ConfigurationManager.AppSettings["db_port"]);
if (db_connection_type == "SID")
this.Sid = ConfigurationManager.AppSettings["db_sid"];
else
this.ServiceName = ConfigurationManager.AppSettings["db_sid"];
this.UserId = db_username;
this.Password = db_password;
this.Open();

我发现了oracleconnection的clearPool ownclass

// C#
// Sample demonstrating the use of ClearPool API in OracleConnection class
using System;
using Oracle.DataAccess.Client;
class ClearPoolSample
{
static void Main()
{
Console.WriteLine("Running ClearPool sample..." );
// Set the connection string
string strConn = "User Id=scott;Password=tiger;Data Source=oracle;" +
"Min pool size=5;";
OracleConnection conn = new OracleConnection(strConn);
// Open the connection
conn.Open();
// Clears the connection pool associated with connection 'conn'
OracleConnection.ClearPool (conn);
// This connection will be placed back into the pool
conn.Close ();
// Open the connection again to create additional connections in the pool
conn.Open();
// Create a new connection object
OracleConnection connNew = new OracleConnection(strConn);
// Clears the pool associated with Connection 'connNew'
// Since the same connection string is set for both the connections,
// connNew and conn, they will be part of the same connection pool.
// We need not do an Open() on the connection object before calling
// ClearPool
OracleConnection.ClearPool (connNew);
// cleanup
conn.Close();
Console.WriteLine("Done!");
}
}
