无法恢复 OrientDB 备份

Question

我无法从备份中恢复 OrientDB 数据库。我使用的是 OrientDB 版本 1.2.0（此备份来自 2012 年 11 月），备份是由 OrientDB（相同版本）使用内置备份实用程序生成的。我正在尝试使用 OrientDB 控制台将备份恢复到新数据库：

create database remote:localhost/dbname root password local graph
import database backup.json

但是当我运行这些命令时，我在控制台中收到以下错误：

Importing indexes ...
- Index 'dictionary'...Error on database import happened just before line 22258, column 6
com.orientechnologies.orient.core.exception.OConcurrentModificationException: Cannot update record #0:1 in storage 'dbname' because the version is not the latest. Probably you are updating an old record or it has been modified by another user (db=v2 your=v1)

所有记录都正确导入，但在索引上失败。我对同一个数据库有 15 个以上的备份，它们都有这个问题，所以它们似乎不太可能全部损坏。如何恢复我的数据库？ （如果需要，我可以修改 JSON。）

当尝试使用本地模式而不是远程模式时，我得到一个不同的错误：

问题似乎是我的旧集群 ID 与新数据库中的不匹配。也许有一些创建选项会影响默认创建哪些集群？

Answer 1

事实证明，问题在于数据库是使用 OrientDB 版本 1.2.0 导入的，但是是使用 1.0.1（或 1.0.0）创建的。 JSON 文件将版本 1.2.0 列为 engine-version，但这是支持它的引擎，而不是创建它的引擎。在我尝试了 Lvca 使用本地模式的建议后，我发现集群 ID 不匹配。从那里我猜到版本号可能不正确。因此，即使我使用 1.2.0 服务器和 1.2.0 Java 库运行数据库，似乎也从未“升级”数据库以使用新的 1.2.0 架构。

感谢 Lvca 朝正确方向轻推。
