Orientdb 阻止简单的文档插入

Question

我对 OrientDB 完全陌生，所以我试图通过简单地插入一个文档来修改它。我查看了一些文档并写下了以下内容:

public static void main(String[] args) {
    ODatabaseDocumentTx db = ODatabaseDocumentPool.global().acquire("remote:localhost/petshop", "admin", "admin");
    try {
        db.begin(OTransaction.TXTYPE.OPTIMISTIC);
        ODocument animal = new ODocument("Animal");
        animal.field( "name", "Gaudi" );
        animal.field( "location", "Madrid" );
        animal.save();
        db.commit();
    } finally {
        db.close();
    }
}

现在文档已插入，我可以从控制台检查，但该程序只是卡在 db.commit();

这是它挂起的线程:

服务器脱口而出以下警告:

2014-05-29 12:03:17:922 WARN Current implementation of storage does not support sbtree collections [ODatabaseRecordAbstract$1]

我错过了什么吗？我使用的是orientdb 1.7。

我像这样创建了数据库:

create database remote:localhost/petshopp root passwd local

虽然我应该使用:

create database remote:localhost/petshopp root passwd plocal
