neo4j - 将 neo4j 数据库从 2.0.1 升级到 2.1.3 失败

Question

我正在尝试将在 Windows 上运行的 Neo4j 商店从 2.0.1 升级到 2.1.3。

我所做的，从工作 2.0.1 开始。环境如下:

• .\2.0.1\bin\neo4jinstall.bat 删除
• xcopy .\2.0.1\data\findsi.graphdb .\2.1.3\data\findsi.graphdb
• .\2.1.3\bin\neo4jinstall.bat 安装

这将失败并显示以下消息: 检测到错误关闭数据库，正在执行恢复..

我的(2.1.3)messages.log 文件告诉我这一点:

现在，如果我执行 .\2.0.1\bin\neo4jinstall.bat install 一切都会再次正常运行，尽管是旧版本。我的猜测是，它与实际数据库无关。

正如文档所述，我通过在 2.1.3 环境中设置 allow_store_upgrade=true 来设置显式升级。

我不愿意手动更改数据库文件夹中的内容，但我确实需要升级，因为它解决了我一直在努力解决的一些性能问题。

Answer 1

可能有2个问题

1. 您是否执行了 xcopy/r(即递归)？
2. Windows 通过硬终止方式终止服务，即不让它正确关闭

因此，在 2.0.1 启动时，它总是必须执行恢复，而 2.0.3 拒绝在非完全关闭的数据库上启动。

您可以通过使用

启动 2.0.1 数据库一次来缓解这种情况

bin\Neo4jShell.bat -path data\findsi.graphdb

使用您的数据库，然后使用quit彻底停止它，然后再复制它。
