Switch between versions of Firebird SQL Server

Pierre — Tue, 01 Dec 2009 15:19:31 +0000

I wrote a little batch script to switch between versions of Firebird SQL Server nearly automatically.

The only one requirement is that all versions must be installed in C:\Program Files\Firebird\ where is Major.Minor version number of the Firebird Server you want to use.

Eg : C:\Program Files\Firebird\1.5, C:\Program Files\Firebird\2.0, C:\Program Files\Firebird\2.1 ...

Just copy the script in C:\Program Files\Firebird and start switching between versions of Firebird :

C:\Program Files\Firebird\> switch 1.5
C:\Program Files\Firebird\> switch 2.0
...

The code :

@echo off
 
if "%OLD_PATH%" == "" (
  set OLD_PATH=%PATH%
)
 
setlocal
 
set FB_KEY=HKLM\SOFTWARE\Firebird Project\Firebird Server\Instances
set FB_VALUE=DefaultInstance
 
for /F "skip=2 tokens=2*" %%A IN ('reg query "%FB_KEY%" /v %FB_VALUE%') do (
  for /F "delims=\ tokens=4" %%Y IN ('echo %%B') do (
    set CURRENT_FB=%%Y
  )
)
 
set VERSION=%1
 
if "%VERSION%" == "" (
  echo Syntax : %0 [1.5 ^| 2.0 ^| 2.1 ^| 2.5 ^| 3.0] [Params for instsvc i^(nstall^)]
  if not %CURRENT_FB% == "" (
    if exist %CURRENT_FB%\bin\instsvc.exe (
      echo.
      echo Tip : These are the available options for instsvc from Firebird %CURRENT_FB%
      %CURRENT_FB%\bin\instsvc.exe
    )
  )
) else (
  if not "%CURRENT_FB%" == "" (
    echo Unregistering Firebird %CURRENT_FB%
 
    pushd %CURRENT_FB%\bin
    instclient r g
    instsvc stop
    instsvc r
    instreg r
    popd  
 
    echo.
  )
 
  echo Registering Firebird %VERSION%
 
  pushd %VERSION%\bin  
  instreg i -z
  instsvc i %2 %3 %4 %5 %6 %7 %8 %9
  instsvc start
  instclient i g
  popd
 
  echo.
 
  echo Defining System Path to search in Firebird %VERSION% tools and some useful environment variables
 
  endlocal 
  set PATH=%OLD_PATH%;"%CD%\%VERSION%\bin"
  set ISC_USER=SYSDBA
  set ISC_PASSWORD=masterkey
 
  echo All Right !
)

Hope this helps

Firebird backup script

Pierre — Thu, 25 Sep 2008 09:29:59 +0000

This is my first released backup script for Firebird RDBMS. It automagically search for all Firebird databases from a central directory, uses gfix to validate them, then backup + gzip them to a central backup directory keeping only 5 last successful backups.

It may be used as a cron script to automate Firebird databases backup.

#!/usr/bin/env bash
#
#   Validate and Backup Firebird databases using Firebird
# standard tools
#
#   You can adjust FB_ROOT, FB_BIN, FB_DATA, Fb_BACKUP and 
# BACKUP_COUNT variables to fit your own requirements. 
# For instance, if you use an official package of Firebird for your
# ditribution, you may have to change FB_ROOT to /usr/bin.
