Tableau Server 如何批量更新数据源服务器名称？

Question

我们的 Oracle 数据库已升级到新服务器，因此它具有新的服务器名称。我们在 Tableau Server 上发布的大多数工作簿都连接到这个 Oracle 数据库。用户名和密码保持不变，但服务器地址已更改。我使用了以下 Python 代码。它可以识别需要服务器地址更新的正确工作簿，但是会产生错误：'PW Update Failed with error:

404004: Resource Not Found
    Datasource '5f125136-22da-48d0-bdc7-8e5edde8d809' could not be found.

''' 如何修复代码？

Answer 1

您必须更新工作簿。

server.workbooks.update_connection(wb, connection)
