BDB
Tables
Here follows the restrictions you have when using BDB
tables:
BDB
tables store in the `.db' file the path to the file as it was
created.
(This was done to be able to detect locks in a multi-user environment that
supports symlinks).
The effect of this is that BDB
tables are not movable between directories!
BDB
tables, you have to either use
mysqldump
or take a backup of all table_name.db
files and
the BDB
log files. The BDB
log files are the files in the base
data directory named log.XXXXXXXXXX
(ten digits);
The BDB
storage engine stores unfinished transactions in the log files
and requires these logs to be present when mysqld
starts.
