I have a GlassFish cluster.

When I tried to add node and a instance, DAS saids a bunch of error messages telling

Resource [ jdbc/xxxx ] of type [ jdbc ] is not enabled

the JDBC Resource is ok and targeted with the cluster.

I've installed the JDBC driver on the new node.

Can anybody help?

----------------------------------------- ANSWER

I found that the JDBC/address has been wrongly set that only one node knows but unknown for others.

I'm answering for my own question.

The JDBC Connection Pool's address property was wrong.

It was a DNS name about which only one of three nodes knows.
