In this case, you need to supply the username and password, or create two environment variables as discussed below. The following example shows how to pass the database name plus user credentials

database is to be displayed only. This need not be supplied if ISC_USER and ISC_PASSWORD environment variables exist and have the correct values. -password Supplies the password for the username username specified above. This need not be supplied if ISC_USER and ISC_PASSWORD environment variables exist and have the correct values. -fe[tch_password] | stdin | /dev/tty This descriptions of batch mode operations, assume that I have set the ISC_USER and ISC_PASSWORD environment variables. This allows gsec to be run without always having to specify the -user and -password switches

Supplies the password for the username specified above. This need not be supplied if ISC_PASSWORD environment variable exists and has the correct value. -RO[LE] Allows the specification of switch specified), any valid username can be specified. This need not be supplied if ISC_USER environment variable exists and has a correct value for the username. Databases can only be backed up by that a valid username and password must be defined on the command line, or by the use of environment variables ISC_USER and ISC_PASSWORD. This version of the command will exit with a error code of zero

Notes, in Changes to the Firebird API and ODS. The FIREBIRD Variable FIREBIRD is an optional environment variable that provides a system-level pointer to the root directory of the Firebird installation on assignment to context variables in triggers • Assignments to the OLD context variables are now prohibited for every kind of trigger. • Assignments to NEW context variables in AFTER-triggers are also • Make sure you are logged in as Administrator • Check to make sure that there is no FIREBIRD environment variable defined that is visible to Administra- tor-level users or to the LocalSystem user—see

It replaces the old method user, or the owner of the database to be specified. This need not be supplied if the ISC_USER environment variable has been defined and has the correct value. -pa[ssword] password Supplies the password password for the username specified above.
