If you are using an internal repository, then use a URL that identifies the local repository. In this example, the Oracle Solaris support repository is the configured package source.
% pkg publisher PUBLISHER TYPE STATUS URI solaris origin online https://pkg.oracle.com/solaris/support/
For a system without a support contract and using the Oracle Solaris release repository, the output would look like:
% pkg publisher PUBLISHER TYPE STATUS URI solaris origin online http://pkg.oracle.com/solaris/release/
