Hi,
I'm using MySQL server version 4.0.15a in an embedded envirionment (as a
standalone server, I'm not using the embedded server library). I have 128 MB
of memory and disk space is tight. I'm using MyISAM tables.
If my system loses power, some tables are left in a corrupt state. As stated
in the MySQL documentation, I think the data tables are OK, its just that
the tables were not closed properly and are considered corrupt by MySQL.
You need to provide a way to have an orderly shutdown on power loss. You are trying to treat the symptom, not the problem.
I need a FAST way to determine if a table is corrupt. I've tried myisamcheck
--fast and --check-only-changed options, and increased the buffer sizes (-O
key_buffer_size and -O sort_buffer_size), as mentioned in the documentation.
The fastest time I can achieve is 6:55.
I've also tried "CHECK TABLE tablename FAST QUICK" on a table I know is
marked as corrupt, and the fastest time I can achieve is 6:58.
I need to detemine if a table is corrupt within a few SECONDS, not minutes.
How can I do this?
The documentation says there is a flag in myisam tables that indicates when
a table is corrupt. Is there a way I can quickly check this flag?
I want to make this an automated check that I can write in C.
Are there third-party tools available to help me?
Thanks, Tim
