recovering tables without having the shared datafile

Hi,

I've read a bunch of articles about the "innodb_file_per table" parameter, but I was wondering if one could recover a database without having the shared ibdata1 data file. In this hypothetical case (which could become real in some point of time) I would have the .frm and .ibd files.

I can imagine certain cases where one would like to move a single innodb database or table without having to move the entire ibdata1 file.

Anyone here has some experience with that?

I've tried dozens of combinations where I would use the "alter table ... import tablespace" to get an old backup of my .ibd file back online.

I also tried discarding my tablespace, dropping the table, removing the ibdata file, restarting the server and recreating the table using a "CREATE TABLE" statement (so far so good). But the final step where I put my old .ibd file and import my table space goes horribly wrong.

90% of al my actions resulted in an error from the storage engine, but the last test gave no error, but resulted in an empty result when I queried the records.

I someone would be able to give me a valid solution, I would not only have an answer to my backup/recovery question, but also a magnificent solution for shrinking my ibdata1 file for tables that were created prior to my "innodb_file_per_table" setting.

Thanks in advance.
Kind regards,

Thijs Feryn
