This database driver might suffer problems because of PC instability or disk damages. Thus that's vitally important to make backups once a day to minimize the chance of data loss.
Plugin does not work under Wine.
Zapewnia obsługę bazy danych Mirandy: ustawień globalnych, kontaktów, historii, ustawień dla każdego kontaktu z osobna.
Wtyczka stworzona w oparciu o bibliotekę libmdbx.
Database repair
Make a backup copy of the damaged database before restoring!
mdbx_chk.exe is located in the Miranda root folder.
mdbx_chk.exe -i -w -v -t -1 "path\to\corrupted.dat"
This command will select the second to last meta page (since the last one is probably pointing to corrupted snapshot).
Each meta page contains the necessary information (number transactions, geometry, etc.) as well as a pointer (usually) to own MVCC snapshot that seems to "float" in many pages along with the rest of the MVCC snapshots. Each such snapshot is generated when the writing transaction is committed.
Database check
mdbx_chk.exe is located in the Miranda root folder.
mdbx_chk.exe -i -v -n -w "path\to\database.dat"
"problems: wrong order of entries" messages should not be considered as errors.
If the above does not help
mdbx_dump.exe and mdbx_load.exe are located in the Miranda root folder.
mdbx_dump.exe -n -a -f "%TEMP%\corrupted.tmp" "path\to\corrupted.dat" mdbx_load.exe -n -a -f "%TEMP%\corrupted.tmp" "path\to\repaired.dat"
This extracts as much data as possible from the corrupted.dat to the temporary file and builds repaired.dat.
