Sebastian, how big is the auto-extending data file? Do you have very many transactions running concurrently in the server? Regards, Heikki

This very table is very small (max. 1000 lines, simple structure:) CREATE TABLE `olap_flight` ( `a` varchar(25) collate latin1_german2_ci NOT NULL, `b` varchar(50) collate latin1_german2_ci NOT NULL, `c` varchar(50) collate latin1_german2_ci NOT NULL, `d` varchar(100) collate latin1_german2_ci NOT NULL, `e` varchar(50) collate latin1_german2_ci NOT NULL, `f` varchar(50) collate latin1_german2_ci NOT NULL, `g` varchar(100) collate latin1_german2_ci NOT NULL, `h` varchar(50) collate latin1_german2_ci NOT NULL, PRIMARY KEY (`a`) ) ENGINE=InnoDB DEFAULT CHARSET=latin1 COLLATE=latin1_german2_ci On disk, the file olap_flight.ibd is takes ~ 280 kb, the frm-file < 10kb (I don't think the frm file is what you were asking for, but anyway, just to be complete) We don't have many transactions in means of BEGIN... COMMIT. The contents of that particular table are deleted and inserted every 10 minutes. But we have dozens of reads (250-300 QPS in peak times) on that DB. I don't know what exactly you are asking for, maybe this helps you: +-----------------------------------+------------+ | Variable_name | Value | +-----------------------------------+------------+ |

Sebastian, are you running out of space in the SYSTEM tablespace? I mean the ibdata files. Undo log is stored there. Have you defined the last ibdata file auto-extending? Regards, Heikki
[2 Jun 2006 7:36]
Sebastian Nohn
The system file is not auto extending.
[2 Jun 2006 9:27]
Heikki Tuuri
Sebastian, please make it auto-extending, and report if you still have this problem. Regards, Heikki

Changing this as a feature request. MySQL should return a more descriptive error message if we run out of space in the ibdata files when we are using innodb_file_per_table.

Just for info: It did not happen anymore since we made the ibdata file autoextending.
