我的 ASP.NET C# 应用程序连接到 Oracle 数据库，运行存储过程，并返回具有 CloseConnection 命令行为的读取器。阅读器本身已被处理，但是 - Oracle 会话在 V$SESSION 中保持为非活动状态。几个小时后，当另一个客户使用该应用程序时，这会变成一个错误，并且我们收到错误“ORA-02399：超出最大连接时间，您正在注销”。进一步尝试连接到 Oracle 返回“ORA-01012：未登录”
这是连接字符串：
User Id=UserID;Password=userPass;Data Source=(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP) (HOST=IP.IP.IP.IP)(PORT=XXXX))(CONNECT_DATA=(SID=SID)));;Max Pool Size=5;Connection Timeout=60;Connection Lifetime=120;
以下是阅读器的使用方法：
using (OracleDataReader dr = OraFunctions.ExecuteReader(input.ConnectionString,
CommandType.Text,
input.SqlStmt,
null))
{
while (dr.Read())
{
//do stuff here
}
dr.Dispose();
}
这是连接到 Oracle 的类：
public static OracleDataReader ExecuteReader(string connectionString, CommandType commandType, string commandText, OracleParameter[] commandParameters) {
OracleConnection connection = null;
OracleCommand command = new OracleCommand();
try {
connection = new OracleConnection(connectionString);
connection.Open();
command.Connection = connection;
command.CommandType = commandType;
command.CommandText = commandText;
if (commandParameters != null) {
foreach (OracleParameter param in commandParameters) {
command.Parameters.Add(param);
}
}
//Passing CommandBehavior.CloseConnection flag to the ExecuteReader method makes the DataReader connection to be closed when the DataReader is closed.
OracleDataReader reader = command.ExecuteReader(CommandBehavior.CloseConnection);
command.Dispose();
return reader;
} catch {
if (connection != null) {
command.Dispose();
connection.Close();
}
throw;
}
}
I'm looking for any hints on why the connections aren't actually closing. I'm using Oracle.DataAccess.Client. My guess is that the datareader's command behavior isn't working and that I need to recode this as a dataset where I can explitictly close the connection without having to rely on the CommandBehavior.
Thoughts? Thanks!
