Question

您好，感谢您阅读此问题。我有定位数据库设置，并希望添加第二个服务器，并让它们彼此之间进行复制。当一个人自己运行它运行良好，我已经使用它几个月。启用hazelcast插件时，服务器开始通信，我可以看到它们开始相互通信。虽然他们试图互相写信时会发生错误。这是同一个问题：

https://groups.google.com/forum/#!topic/orient-database/QpZPG4y_KpU

为了它的价值，我将这两台服务器部署在同一台机器上，每台服务器都有自己的嵌入式数据库。数据库路径是plocal：/ home / chris / dbs / db2和plocal：/ home / chris / dbs / db1

2015-10-08 08:56:14:048 INFO  [db2-orient] Saving distributed configuration file for database 'db' to: ./databases/db/distributed-config.json [OHazelcastPlugin]
2015-10-08 08:56:14:049 INFO  [db2-orient] received new status idp2-orient.idp=SYNCHRONIZING [OHazelcastPlugin]
2015-10-08 08:56:18:054 WARNING [db2-orient]->[[db1-orient]] requesting deploy of database 'db' on local server... [OHazelcastPlugin]

然后在另一台服务器上，首先启动的那个，我看到了

[OHazelcastPlugin]{db=db} [db1-orient]<-[db2-orient] error on executing distributed request 0: deploy_db
com.orientechnologies.orient.server.distributed.ODistributedException: Distributed storage was not installed for database 'db'. Implementation found: com.orientechnologies.orient.core.storage.impl.local.paginated.OLocalPaginatedStorage
at com.orientechnologies.orient.server.hazelcast.OHazelcastPlugin.executeOnLocalNode(OHazelcastPlugin.java:745)
at com.orientechnologies.orient.server.hazelcast.ODistributedWorker.onMessage(ODistributedWorker.java:298)
at com.orientechnologies.orient.server.hazelcast.ODistributedWorker.run(ODistributedWorker.java:121)

我在抛出该异常的行上放置了一个断点，并且当时存在的存储类型确实是OLocalPaginatedStorage。我的orientDB版本是2.0.15。

我的分布式配置。（两台服务器都相同）

{
"autoDeploy": true,
"hotAlignment": false,
"executionMode": "undefined",
"readQuorum": 1,
"writeQuorum": 2,
"failureAvailableNodesLessQuorum": false,
"readYourWrites": true,
"clusters": {
    "internal": {
    },
    "index": {
    },
    "*": {
        "servers" : [ "<NEW_NODE>" ]
    }
}

}

这就是我启动服务器的方式。它是嵌入式的，并通过java应用程序启动。

OServer server = OServerMain.create(true);
OPartitionedDatabasePool pool = server.startup(config.toString()).activate().getDatabasePoolFactory().get(dbPath, OUser.ADMIN, OUser.ADMIN);

服务器用于启动的配置是

正如wolf4ood指出的那样，存储类型被hazelcast插件的onOpen方法中的hazelcast插件所取代。分页存储切换到分布式。如果路径不以“plocal：./ databases”开头，则不会发生此替换。解决方案：使路径以此开头。我不知道这是不是一个好主意。那个检查似乎在那里有一个原因，代码中的注释似乎表明在同一个jvm上运行的东西。
