How can I connect to a database to call configuration functions?

You can use the josql SQL command utility to connect to network by using:

josql <network> <user> -h <host>

where:

<network> is the name of the network you want to connect to

<username> is the username you wish to connect as

<host> is the host address of a catalog server.

If you want to perform administration functions such as creating or dropping users, roles or networks, then use star\$administration rather than the network name.
