Subject [jira] Resolved: (DERBY-3729) Error message is rather unrevealing when creating large databases on FAT32 drives
Date Fri, 19 Feb 2010 20:00:28 GMT

     [ https://issues.apache.org/jira/browse/DERBY-3729?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Bryan Pendleton resolved DERBY-3729.
------------------------------------

       Resolution: Fixed
    Fix Version/s: 10.6.0.0

Thanks Knut Anders for the various reviews and suggestions. I think that
this change is about as good as it's going to get in my client, so I've committed
it to the trunk so we can get some additional experience with it there.

Committed to subversion as revision 911955.

> I was creating a test database on an external USB drive formatted as FAT32- it contains
some tables that have quite large binary objects in: This was in conjunction with Hibernate.
I got this rather cryptic error message.

> Initially it didnt even occur to me that this may be due to me using a FAT32 drive, but
eventually I figured out that the table's file had got to the operating FAT32 limit: I had
a file of 4,194,272 KB.

> The error is still strictly speaking incorrect - my disk is far from full, but I have
created a file too big for the disk type - but the error is at least closer to the truth and
this would be useful information for the derby client to display rather than the rather scary
looking message I was getting.
