When using relstorage + MySQL it creates seven tables to storage all objects, following: mysql> show tables; | current_object - ENGINE=InnoDB | new_oid - ENGINE=MyISAM | object_ref - ENGINE=MyISAM | object_refs_added - ENGINE=MyISAM | object_state - ENGINE=InnoDB | pack_object - ENGINE=MyISAM | pack_state - ENGINE=MyISAM | pack_state_tid - ENGINE=MyISAM | transaction - ENGINE=InnoDB As you see there are tables using both InnoDB and other using MyISAM, thats default setup relstorage do Regards, - - iarlyy selbir | ski0s :wq!

Just a guess, but it looks like you are trying to get a transaction lock on a mysql table, so does the mysql table you are using have a storage engine that supports transactions (eg. InnoDB)?

few days ago my I'm getting this errors when trying logging on /manage, googling I don't found any reasonable solution and/or information about, only thing was, "restarting zope instances works", thats true
Traceback:

StorageError: Unable to acquire commit lock
I looked at the code and this function _hold_commit_lock has the following SELECT statement:
SELECT GET_LOCK(CONCAT(DATABASE(), '.commit'), %s)
I tried to reproduce it querying manually but it looks like an unknown command, and other point, I don't know what Zope put in %s variable.
Does anybody already had this problem?
Thanks for any reply.
