将neo4j数据库从2.0.1升级到2.1.3失败 [英] Upgrading a neo4j database from 2.0.1 to 2.1.3 fails

问题描述

我正在尝试将Windows上运行的neo4j存储从2.0.1升级到2.1.3.

I'm trying to upgrade my neo4j store, running on windows, from 2.0.1 to 2.1.3.

从工作的2.0.1开始，我做了什么.环境，如下所示:

What i have done, starting with a working 2.0.1. environment, is the following:

• .\ 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: Detected incorrectly shut down database, performing recovery..

This will fail with the message: Detected incorrectly shut down database, performing recovery..

我(2.1.3)的messages.log文件告诉我:

My (2.1.3) messages.log file tells me this:

现在，即使我使用的是旧版本，如果我执行.\2.0.1\bin\neo4jinstall.bat install，一切都将再次正常运行.我的猜测是，它与实际数据库无关.

Now, if i do .\2.0.1\bin\neo4jinstall.bat install everything works fine again, albeit with the old version. My guess is, that it has not to do with the actual database.

如文档所述，我通过在2.1.3环境中设置allow_store_upgrade=true进行了显式升级的设置.

As the documentation states, i did setup for an explicit upgrade by setting allow_store_upgrade=true in my 2.1.3 environment.

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

I'm reluctant to manually change things in my database folder, but i do need the upgrade, as it solves some performance issues i have been struggling with.

推荐答案

可能有2个问题

1. 您是否进行过xcopy/r(即递归)操作?
2. Windows会强行终止服务，即无法正确关闭服务

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.

So on 2.0.1 at startup it always has to perform recovery and 2.0.3 refuses to start on a non-cleanly shut down database.

您可以通过

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

与您的数据库一起使用，然后在复制之前用quit干净地将其停止.

with your db and then stopping it cleanly with quit before copying it over.
