EZConnect is a new’ish connector string type which you can use, say, in OLEDB connections strings or connecting to a Database with SQLPlus.

The format goes like this;

<username>/<password>@<connect identifier>

where <connect identifier> has the following form;

[//<host>:<port>/]<servicename>

E.g.

phil/mypass@//devhp1xp:1521/2k_corp01
