Administration tools
Firebird comes with a number of administration command-line tools:
isql | Command-line interactive tool for the execution of DDL and DML commands and scripts. |
gbak | Backup, restore. |
gfix | Various parameters, repair. |
gsec | User administration. |
gstat | Statistics. |
fbmgr | Linux only: starts and shuts down the Firebird demon. |
nbackup | Incremental backups. |
instsvc | Service setup. |
instreg | Registry parameters setup. |
We recommend the comprehensive tool, IBExpert (https://www.ibexpert.com), which also offers a free Personal Edition?, for working with Firebird. This tool is however only available for Windows.
You can also download the free "FbAdmin" from the Consic homepage. This is a simple, German-language administration program, that covers the most important administrative tasks: https://www.consic.de/firebird.
ISQL
The ISQL
utility ("Interactive SQL") can be found in the Firebird installation's bin
directory. When started it reports back with an SQL
prompt:
SQL> _
Each command must end with a semicolon to be executed. Commands can also extend over several lines, from the second line onwards they must be preceded with CON>
(Continue) as a prompt.
Create a database
Use the following command to create a new, empty database:
SQL> create database 'c:\test.fdb' CON> user 'SYSDBA' CON> password 'masterkey' CON> page_size 4096 CON> default character set iso8859_1 ;
A page size of 4096
bytes is considered optimal for up-to-date server operating systems. The page size hast to be a multiple of 1024
.
Following the database creation, you should convert to SQL Dialect 3. This can be done using the GFIX
utility (detailed in a separate chapter):
gfix c:\test.fdb -user SYSDBA -password masterkey -sql_dialect 3
Connect to a database
SQL> connect 'c:\test.fdb' user 'SYSDBA' password 'masterkey';
Use this command to test to connect to a database.
Closing ISQL
ISQL
can be closed using the commands, QUIT
or EXIT
. EXIT
commits the current transaction first, QUIT
rolls the current transaction back.
Executing an SQL script file
isql -i C:\DB\myscript.sql
The script file should include a CONNECT
command for the database connection. Alternatively the database can be named, along with the user name and password, directly:
Starting ISQL
with a direct database connection
isql c:\test.fdb -user SYSDBA -password masterkey
Determining the database SQL dialect
SQL> show sql dialect; Client SQL dialect is set to:3
and database SQL dialect is:3
.

ISQL
GSEC
: user administration
The users of all databases run by one service are stored in the security database, security.fdb
. There is alway at least one user, the Database Administrator, SYSDBA
.
Following the installation of a new service, the SYSDBA
's password is set to masterkey
. (Exception: Firebird for Linux, see Installing on Linux).
Only the first 8 characters of a Firebird password are significant. A password may not contain any spaces.
Starting GSEC
GSEC
can only be started by the SYSDBA
.
To start GSEC
on the local server, enter:
gsec -user sysdba -password <password> [options]
To start GSEC
for a server in the network, enter:
gsec -user sysdba -password <password> -database <databasename>
where <databasename>
is the name of the security.fdb
database on the server.
GSEC
can be used as an interactive command-line tool. Alternatively the commands can also be input directly on a command line.
Commands
di[splay] | Displays all users. |
di[splay] <username> | Displays all information for the specified user (excepting the password). |
a[dd] <username> -pw <password> [options] | Insert a new user. |
mo[dify] <username> [options] | Alters the user. |
de[lete] <username> | Deletes the user. |
h[elp] oder ? | Displays the help. |
q[uit] | Ends the interactive mode. |
z | Displays the GSEC version number. |
If you do not wish to start the interactive mode, all commands may be entered directly in the command line. Each command then need to be preceded by a hyphen ("-").
Options
-pa[ssword] <password> | The password of the user carrying out the alterations. |
-user <username> | The user name of the user carrying out the alterations. |
-pw <password> | Password of the user being altered or new password. |
-fname <first name> | First name of the user being altered. |
-mname <middle name> | Middle name of the user being altered. |
-lname <last name> | Last name of the user being altered. |
Examples
Add the user Elvis Presley as user name, ELVIS
, the password is Aaron
:
gsec -user SYSDBA -password masterkey GSEC> add elvis -pw Aaron -fname Elvis -lname Presley GSEC> quit
Change user ELVIS
's password to chuck
:
gsec -user SYSDBA -password masterkey GSEC> modify elvis -pw chuck GSEC> quit
On Linux, change the SYSDBA
password from harry
to hamburg
:
gsec -user SYSDBA -password masterkey -database
-> harry:/opt/firebird/security.fdb -modify sysdba -pw hamburg
On Windows, change SYSDBA
's password from Sally
to hannover
:
gsec -user SYSDBA -password masterkey -database ->sally:"C:\Program Files\Firebird\security.fdb"
->-modify sysdba -pw hannover
Change SYSDBA
's password on server, jake
, on TCP port 3051
to london
:
gsec -user SYSDBA -password masterkey -database
-> jake/3051:/opt/firebird/security.fdb" -modify sysdba -pw london
Delete user JOE
on the local server:
gsec -user SYSDBA -password masterkey -delete joe
