oracle - 在 Linux 中使用 PowerShell 连接到 Oracle Autonomous db

标签 oracle powershell ubuntu odp.net

我在云中设置了一个自治 Oracle 数据库，并且可以通过许多不同的路径成功访问它，SQL 开发人员 (Linux)、PowerShell (Linux) 和 cx_python(Linux)，原因我自己最清楚我想看看我是否可以在 VS Code 中使用 Linux 上的 PowerShell 连接到同一个数据库。
我有

  • 下载钱包，放在目录/home/simon/Documents/Wallet_DB202006252115。
  • Oracle.ManagedDataAccess.Core.2.19.101 已安装
  • 已安装 Microsoft.NETCore.App 5.0.2。

    • 我从 VS Code 运行的基本 PowerShell(PowerShell 集成控制台 v2020.6.0)代码是
    $connectionstring = 'User Id=' + $username + ';Connection Timeout=120 ;Password=' + $password + ';Data Source=' + $datasource
$con = New-Object Oracle.ManagedDataAccess.Client.OracleConnection($connectionstring)
$con.TnsAdmin='/home/simon/Documents/Wallet_DB202006252115'
$con.WalletLocation='/home/simon/Downloads/Wallet_DB202006252115'
$con.Open()
    使用用户 ID 等进行适当设置。它正在正确读取 TNS 数据，就好像我更改了它给出 TNS 错误的源名称一样。 DLL 已成功加载，因为我可以访问连接对象。
    通过此设置，我收到以下错误
    Automation.MethodInvocationException: Exception calling "Open" with "0" argument(s): "ORA-00542: Failure during SSL handshake"
 ---> Oracle.ManagedDataAccess.Client.OracleException (0x80004005): ORA-00542: Failure during SSL handshake
 ---> OracleInternal.Network.NetworkException (0x80004005): ORA-00542: Failure during SSL handshake
 ---> System.Security.Authentication.AuthenticationException: Authentication failed, see inner exception.
 ---> Interop+OpenSsl+SslException: SSL Handshake failed with OpenSSL error - SSL_ERROR_SSL.
 ---> Interop+Crypto+OpenSslCryptographicException: error:14094410:SSL routines:ssl3_read_bytes:sslv3 alert handshake failure
   --- End of inner exception stack trace ---
    有什么建议么..
    谢谢

The trace continues  like - this trying various ports? until it gives the error shown above.

    最佳答案

    从跟踪中看不是特别明显，但问题是由于我使用的是 Net Core 5 而不是 3.1 造成的，切换到较旧的运行时可以使连接正常工作。
