简单文档插入上的Orientdb块

我是OrientDB的新手，所以我尝试通过插入一个文档来修补它。 我查阅了一些文档并写了以下内容：

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();
    }
}

现在插入文档，我可以从控制台检查，但是这个程序只是挂在db.commit（）中

以下是它挂起的线程：

我错过什么了吗？我正在使用orientdb 1.7。

我创建了如下数据库：

create database remote:localhost/petshopp root passwd local

虽然我应该使用：

create database remote:localhost/petshopp root passwd plocal

您是否已将数据库创建为“local”或“plocal”？local，有什么区别？好的，在文档中找到了关于它的注释。如果您愿意，可以将您的注释作为答案发布，我将接受它

create database remote:localhost/petshopp root passwd plocal
