James fails to create mysql tables with mysql-4.1.
--------------------------------------------------

         Key: JAMES-524
         URL: http://issues.apache.org/jira/browse/JAMES-524
     Project: James
        Type: Bug

    Reporter: Norman Maurer
 Assigned to: Norman Maurer 


>From Maillinglist:

Hi,

I'd like to point out to the list a problem with James and MySQL 4.1. The character set support
was
revamped from MySQL 4.0 to MySQL 4.1, and as a result on some systems (in my case, Gentoo)
UTF-8 is
now the default character set on install.

This is a problem when creating the spool, inbox and deadletter tables. The primary key for
these
tables is (message_name, repository_name). On my system MySQL allows for 3 bytes per UTF-8
character, and has a maximum key length of 1000 bytes. Since message_name is 200 chars and
repository_name is 255 chars by default, the key length exceeds 1000 bytes and the table cannot
be
created.

The key length issue in MySQL is better described here:
http://www.xaprb.com/blog/2006/04/17/max-key-length-in-mysql/

I managed to solve the problem by reducing the length of repository_name to 128 chars.

Ciao,
Craig
