OrientDB - How can I create database on a clustering servers? - distributed

Question

I setup two nodes with the default configuration, cluster status:
"members": [{
"id": "192.168.1.101:2434",
"listeners": [{"protocol": "ONetworkProtocolBinary", "listen": "192.168.1.101:2424"}, {"protocol": "ONetworkProtocolHttpDb", "li
80"}],
"alias": "192.168.1.101:2434",
"status": "aligning"
}, {
"id": "192.168.1.102:2435",
"listeners": [{"protocol": "ONetworkProtocolBinary", "listen": "192.168.1.101:2425"}, {"protocol": "ONetworkProtocolHttpDb", "li
80"}],
"alias": "192.168.1.101:2435",
"status": "aligning"
}],
"name": "_hzInstance_1_orientdb",
"local": "192.168.1.101:2435"
}
but when I use Java API to connect to one server, and tried to create a database, exception occurs,
admin = new OServerAdmin(PATH);
admin.connect("root", "password");
if (!admin.existsDatabase()) {
admin.createDatabase("document", "local");
}
stack:

Why this happen? How can I craete database on a clustering servers?
THX.

Answer 1

The initial creation of database must be done outside the cluster. Then copy the database to all the servers and startup the cluster.
