我对以上内容感到困惑，每当我在新的Oracle安装中执行包中的存储过程时，它会间歇性地出现。
从WCF调用sproc，它返回以下异常：

它似乎也不是一种模式 - 有时它工作正常，有时它不会。
这是我尝试过的东西：
确保在通用代码中处理对象。这是目前使用的测试代码：
using System.Data;
using System.Data.Common;
using Oracle.ManagedDataAccess.Client;
/// <summary>
/// Extensions for xxxxx.
/// </summary>
/// <seealso cref="System.Data.Entity.DbContext" />
public partial class xxxxEntities
{
public virtual DataSet ExecuteStoredProcedureAsDataSet(string storedProcName, int commandTimeoutSeconds, object[] parameters)
{
var sqlCommand = this.Database.Connection.CreateCommand();
var resultSet = new DataSet();
sqlCommand.CommandType = CommandType.StoredProcedure;
sqlCommand.CommandTimeout = commandTimeoutSeconds;
sqlCommand.CommandText = storedProcName;
sqlCommand.Parameters.AddRange(parameters);
var referenceCursor = new OracleParameter("P_DATAOUT", OracleDbType.RefCursor)
{
Direction = ParameterDirection.Output
};
sqlCommand.Parameters.Add(referenceCursor);
using (var adapter = CreateDataAdapter(this.Database.Connection))
{
adapter.SelectCommand = sqlCommand;
adapter.Fill(resultSet);
}
referenceCursor.Dispose();
sqlCommand.Dispose();
return resultSet;
}
/// <summary>
/// Creates the data adapter.
/// </summary>
/// <param name="connection">The connection.</param>
/// <returns>DbDataAdapter.</returns>
DbDataAdapter CreateDataAdapter(DbConnection connection)
{
return DbProviderFactories.GetFactory(connection).CreateDataAdapter();
}
}
将存储过程中的查询减少到“已修复”状态。值 - 确保在sproc中没有任何内容导致问题。我确实发现了下面描述的一些有趣的问题。
所以，我不知所措。我打开了ODP跟踪 - 并注意到在处理池时似乎遇到了问题。第一次，我得到了这个：

我通过注释掉select语句和where子句来调整sproc中的查询，并逐步将它们重新引入以查看它是否是问题的查询（在Oracle Developer中运行它的工作原理）不过很好）。我已将其缩小到此声明 - 如果我重新引入它，我会再次收到文件结束异常：
WHERE
-- Only handle records that contain a numeric value in the ref field.
ISNUMERIC(PTT.REF_FIELD_2) = 1
这是ISNUMERIC函数在包中的样子;
FUNCTION ISNUMERIC (p_string IN VARCHAR2) RETURN INT
IS
v_new_num NUMBER;
BEGIN
IF p_string IS NULL
THEN
RETURN 0;
END IF;
v_new_num := TO_NUMBER(p_string);
RETURN 1;
EXCEPTION
WHEN VALUE_ERROR THEN
RETURN 0;
END ISNUMERIC;
起初我认为可能是由于异常数量而导致阻止进一步执行的异常数量。但是我将功能简化为只返回＆＃39; 1＆＃39;它每次都不起作用。
查询结果通过ref游标传回，例如
PROCEDURE DEVSP_API_GETxxxx(
P_STARTDATE IN DATE
, P_ENDDATE IN DATE
, P_xxx IN P_xxx_TYPE
, <snip>
, P_DATAOUT OUT sys_refcursor
) AS
BEGIN
OPEN P_DATAOUT FOR
SELECT
'asdsa' as "x",
'sadasdsad' as "z",
0 as "Qty",
<snip>
最后，我从select语句和where子句中删除了所有函数调用 - 并立即停止发生错误 - 我用函数运行的相同逻辑替换它们 - 只是在SELECT和WHERE语句中内联。 / p>
那是怎么回事？在包含函数调用的包中运行sprocs时，ODP.net是否有限制？似乎有点奇怪。
解决方法是不使用函数，但我不想这样做，因为一些select语句中有条件表达式，它们在基于联合的查询中重复相同的逻辑。
非常感谢任何帮助或指示！
聚苯乙烯。为了透明，我上周在Oracle论坛上发布了这个，但没有回复。

我还可以在同一个文件夹中看到核心转储。我已经尝试在那里点击存储桶跟踪文件，看看是否有任何明显的东西 - 但说实话，当你不知道自己是什么时，很难找到什么东西？＃39 ;正在寻找！
我可以看到以前使用函数时运行sprocs的核心转储的大量转储 - 所以它至少是合理的一致。
答案 0 :(得分：1)
我遇到了同样的问题。 Oracle Support回复：
看起来你正在攻击Bug 18191823 - Hang / ORA-600 [19708]等。引用陈旧的REFCURSOR绑定（Doc ID 18191823.8）
解决方法
确保绑定的PL / SQL变量的持续时间至少与绑定到的ref游标的持续时间一样长。
此修复程序首先包含在2016年7月的修补程序中。
