We have a 4 part fix process for fixing database, first two commands are gfix and the final two are gbak.
1. %gfix% -v -ignore -full -user SYSDBA -password masterkey %1
2. %gfix% -mend -ignore -user SYSDBA -password masterkey %1
3. %gbak% -b -g -ig -v -user SYSDBA -password masterkey %1 %2
4. %gbak% -c -v -p 8192 -user SYSDBA -password masterkey %1 %2
Sometimes it is necessary to add the –i switch to the 4th command line so that indexes aren’t reactivated upon restore where data is missing that causes the restore to fail. You then have to turn the indices back on individually and fix any data related issues until all indices and referential constraints are all resolved and reactivated successfully.
This process fixes most database corruption issues and has been gleaned from a variety of sources over the last few years, it works for v2.1 & v2.5.
Cheers,

Subject: [firebird-support] Error on Gfix
Hi!
I'm using Firebird 2.5.x and the command gfix -v -full returned:
Summary of validation errors
Number of record level errors : 3
Number of database page errors : 1993
What I have to do in order to fix it, without a backup/restore? I read in "Firebird Documentation" that the command gfix -v -full will fix the orphan pages and record level erros, however, every time when i ran "gfix -v -full" is returned the error above.
