Member Function Documentation

check()

void Validate_files::check ( const Const_iter &  begin, const Const_iter &  end, size_t  thread_id  )

private

Validate a range of tablespaces from the DD.

1. Compare the discovered files against those known to the dictionary.
2. Open any tablespace known to the DD but not discovered and opened from the known directories.
3. Update the DD if a tablespace has moved.
4. Update the DD if an undo tablespace was truncated and replaced.
5. If innodb_validate_tablespace_paths is set and this is not called while in recovery, only validate undo tablespaces.
6. Track the number of skipped, moved, missing and deleted tablespaces.
7. Return failure for any unexpected error.

   Parameters

   [in]	begin	Start of the slice
   [in]	end	End of the slice
   [in]	thread_id	Thread ID

failed()

bool Validate_files::failed ( ) const

inlineprivate

Returns

true if there were failures.

get_space_max_id()

space_id_t Validate_files::get_space_max_id ( ) const

inlineprivate

Returns

the maximum tablespace ID found.

validate()

dberr_t Validate_files::validate

(

const DD_tablespaces &

tablespaces

)

Validate the discovered tablespaces against the DD and attempt to open any DD tablespace not already open using a Parallel For Loop (par_for).

Parameters

[in]

tablespaces

Tablespace files read from the DD

Returns

DB_SUCCESS if all OK
