Multi-db remote server connection?


I have two server.The first server is a web server and
I want to use the second server as the database server.

I'm using db tools

add_db_server('000', 'dc1', 1, 1,'myserverip','', 'mydb_000', 'myrootuser',  'myrootpassword');

I think,I don't do any mistake.Because it works locally before and I'm sure my database server support remote connection.

Local Host DB: I left this blank,, (I tried three)

but still didn't work

any idea?
