recovering InnoDB (1 reply)

Hi there,

with a database "mymediawiki" I ran into serious trouble. The
database consists of InnoDB tables.

I can see the tables with the "show tables"-command
like so:

mysql> show tables;
+------------------------+
| Tables_in_mymediawiki |
+------------------------+
| archive |
| table3 |
| table3 |

...

However, when I try to access a
table I get the error message, that the table does not exist:


mysql> select * from archive;
ERROR 1146 (42S02): Table 'mymediawiki.archive' doesn't exist
mysql>

mysql> repair table archive;
+----------------------+--------+----------+--------------------------------------------+
| Table | Op | Msg_type | Msg_text |
+----------------------+--------+----------+--------------------------------------------+
| mymediawiki.archive | repair | Error | Table 'mymediawiki.archive' doesn't exist |
| mymediawiki.archive | repair | status | Operation failed |
+----------------------+--------+----------+--------------------------------------------+
2 rows in set (0,01 sec)

mysql>


Then I tried to repair the tables on the shell:

# cd /var/lib/mysql/mymediawiki
# mysqlfrm --basedir=/etc/mysql --user=mysql mymediawiki:archive.frm --port=3333
Spawning server with --user=mysql.
Starting the spawned server on port 3333 ... ERROR: Cannot find location of mysqladmin.


So as you can see it is the database of a wiki. Maybe someone has experience with
this special situation.
Can you get started on how to recover the database ?

Thanks a lot.

Best!
