连接到某些数据库时，打开连接时收到以下错误消息。调用者是一个TransactionScope。

从应用程序：

MTSRMManager.CCPEnlistDistributedTxnToSysTxn(OracleConnectionImpl connImpl, Transaction txn, MTSTxnRM txnRM, MTSTxnBranch txnBranch)
MTSRMManager.CCPEnlistTransaction(OracleConnectionImpl connImpl, Transaction transaction, MTSTxnRM txnRM, MTSTxnBranch txnBranch)
PoolManager`3.GetEnlisted(ConnectionString csWithDiffOrNewPwd, Boolean bGetForApp, OracleConnection connRefForCriteria)
OracleConnectionDispenser`3.Get(ConnectionString cs, PM conPM, ConnectionString pmCS, SecureString securedPassword, SecureString securedProxyPassword, OracleConnection connRefForCriteria)
OracleConnection.Open()

从 Oracle.DataManagesAccess 跟踪：

有些工作就好了。

我试过启用其中一些设置但没有运气

<setting name="LegacyTransactionBindingBehavior" value="1"/>
<setting name="PromotableTransaction" value="Promotable" />
<setting name="DynamicEnlistment" value="1" />
<setting name="Pooling" value="false"/>

我们正在将之前访问 Oracle 11g 的代码迁移到 Oracle 19c。

我正在使用 Oracle.ManagedDataAccess 21.4.0。同样的问题发生在 19.13.0
