Nathan, you are very brave using MySQL 5.0.4 which is not General Release yet ;-) If there is no compelling reason to use 5.0.4 (such as stored procedures), then I think you will definitely solve your problem by switching to the GA of 4.0 or 4.1. On the other hand you could try altering your 5.0.4 tables to use InnoDB engine which does row locks rather than the complete table locks that MyISAM does for a single row read.

Regards,

-Kieran

I am using MySQL 5.0.4 with WebObjects 5.2.4 on Tiger and since the upgrade, I have an issue with Table Locking in MySQL. I get this error if I try to access the table:

Next exception:SQL State:HY000 -- error code: 1099 -- msg: Table 'Invmstr' was locked with a READ lock and can't be updated

I'm not sure if the issue is related to the JDBC driver on Tiger which I'm using 'mysql-connector-java-3.1.7-bin.jar'......or if it is related to the MySQL or if it's related to EOF on Tiger ??
I had been developing this application for a couple months now and have never run into this issue until I did the upgrade. Anybody ever run into this table locking issue with MySQL ??   The tables engines are MyISAM..........


Can anybody shed any light about this ?
thx,
nathan
