one of my firebird databases got corrupt in the last couple of days. It's a pretty big one the FDB file is 8 GB.
The error I observed in the applications logfiles. It happens when the users try to run a specific SP. The error message is:
# -902 # database file appears corrupt (/data/firebird/vec.fdb) wrong page type page 112600 is of wrong type (expected 5, found 7) At procedure ''SCOR_CANDIDAT'' line: 38, col: 3
The 38th line of this SP is an UPDATE command on a huge table.
I tried to fetch that table and it shows the same error at line 115904. (I have 125556 records in the table...at least this is what i calculated from ID value of corrupted line subtracted from generator value)
I tried to backup the database to see what happens. The same output comes from gbak:
gbak: ERROR:database file appears corrupt (/data/firebird/vec.fdb)
gbak: ERROR: wrong page type
gbak: ERROR: page 112600 is of wrong type (expected 5, found 7)
gbak: ERROR:gds_$receive failed
gbak:Exiting before completion due to errors
The FireBird Server version is: firebird-superclassic-18.104.22.168539.0-1.el6.x86_64
Running on a 64bit CentOS Linux.
Can anyone help me repair it?
