The optional online parameter specifies that the jadregb program attempts to sign on to the JADE Remote Node Access utility (jadrap) to update the licence key.
If you specify the online parameter, you may also need to specify the ini parameter, which consists of the full (absolute) path and name of the JADE initialization file that enables the jadregb program to obtain the multiuser initialization file settings that it requires to sign on to the JADE Remote Node Access utility (jadrap).
If you do not specify the online parameter, the _control.dat file is updated directly and no client application or database server can be running.
