If you @code{mysqld} is running, you must force a sync/close of all

tables with @code{FLUSH TABLES} and ensure that no one is using the

@code{key_buffer_size} is only used when you check the table with @code{-e} or

repair it with @code{-o}.

@code{sort_buffer_size} is used when you repair the table with @code{-r}.

@code{sort_buffer_size} is used when the keys are reparied by sorting

keys, which is the normal case when you use @code{--recover}.

@code{key_buffer_size} is used when you are checking the table with

@code{--extended-check} or when the keys are repaired by inserting key

row by row in to the table (like when doing normal inserts). Repairing

through the key buffer is used in the following cases:

@itemize @bullet

@item

If you use @code{--safe-recover}.

@item

If you are using a @code{FULLTEXT} index.

@item

If the temporary files needed to sort the keys would be more than twice

as big as when creating the key file directly.  This is often the case

when you have big @code{CHAR}, @code{VARCHAR} or @code{TEXT} keys as the

sort needs to store the whole keys during sorting. If you have lots

of temporary space and you can force @code{myisamchk} to repair by sorting

you can use the @code{--sort-recover} option.

@end itemize

Reparing through the key buffer takes much less disk space than using

sorting, but is also much slower.

If you want a faster repair, set the above variables to about 1/4 of your

available memory.  You can set both variables to big values, as only one

If you have lots of memory, you should increase the size of

@code{key_buffer_size}!

@item -n or --sort-recover

Force @code{myisamchk} to use sorting to resolve the keys even if the

temporary files should be very big.  This will not have any effect if you have

fulltext keys in the table.

@item --character-sets-dir=...

Directory where character sets are stored.

@item --set-character-set=name

index file is truncated at start, so one usually ignore this space.

This space is needed on the same disk as the original index file!

When using @code{--repair} (but not when using @code{--safe-repair}, you

will need space for a sort buffer for:

When using @code{--recover} or @code{--sort-recover}

(but not when using @code{--safe-recover}, you will need space for a

sort buffer for:

@code{(largest_key + row_pointer_length)*number_of_rows * 2}.

You can check the length of the keys and the row_pointer_length with

@code{myisamchk -dv table}.

@end itemize

If you have a problem with disk space during repair, you can try to use

@code{--safe-repair} instead of @code{--repair}.

@code{--safe-recover} instead of @code{--recover}.

@itemize bullet

@item

Fixed 'no found rows' bug in @code{MyISAM} tables when a @code{BLOB} was

first part of a multi-part key.

@item

Fixed bug where @code{CASE} didn't work with @code{GROUP BY}.

@item

Added option @code{--sort-recover} to @code{myisamchk}.

@item

@code{myisamchk -S} and @code{OPTIMIZE TABLE} now works on Windows.
