public class Program {
static String _storageType = "memory";
static String _databaseName = "TestDB";
public static void main(String[] args) throws IOException {
OServerAdmin server = new
OServerAdmin("remote:localhost").connect("root", "root");
server.createDatabase(_databaseName, "graph", _storageType);
server.close();
ODatabaseDocumentTx database = null;
ODatabaseDocumentPool pool;
try {
pool = new ODatabaseDocumentPool("remote:localhost/" +
_databaseName, "admin", "admin");
database = pool.acquire();
ODocument doc = new ODocument("Person");
doc.field("Name", "Johny");
doc.save();
} finally {
if (database != null) {
database.close();
}
}
server = new OServerAdmin("remote:localhost").connect("root", "root");
if (server.existsDatabase(_storageType)) {
server.dropDatabase(_storageType);
}
server.close();
}
}
This works for me.
