IBFirstAID Diagnostician

Version
1.0
IBFirstAID is a tool for automatic diagnose and
repairing of corrupted InterBase/Firebird databases.
Diagnostics features allow you to checkup the
database's health and prevent the possible serious
problems with corruptions. Repairing capabilities of
IBFirstAID allow you to save data after heavy
corruptions: when gfix fails, IBFirstAID will save
your data. It can repair up to 80% of the most
prevalent corruptions.
The main target corruption's types which IBFirstAID is
intended to fix are listed below:
- Internal gds software consistency check (cannot find
tip page (165)) The required TIP pages are lost and
engine cannot open the database. IBFirstAID repairs
the missed pages and recovers the database.
- Unknown database I/O error for file "*.gdb". Error
while trying to read from file. Usually it indicates
that many pages are lost in the end of the file
(probably power failure?). The engine cannot open the
database, so gfix fails. IBFirstAID recreates the
missed system pages and cuts the wrong links.
- Database file appears corrupt. Wrong page type. Page
NNN is of wrong type (expected X, found Y) This error
can mean the various things, but usually the database
file has missed pages. For example, if expected=5, it
means that some table data are corrupted - it may
prevents the backup or make this table unavailable.
IBFirstAID fixes the wrong page's links and repairs
the database.
- Wrong record length. IBFirstAID checks every record
in database and can repair some record-level errors.
- Other database corruptions caused by lost pages.
