Subject [jira] [Commented] (DERBY-4805) Increase the length of the RDBNAM field in the DRDA implementation
Date Wed, 08 Jan 2014 01:03:09 GMT

    [ https://issues.apache.org/jira/browse/DERBY-4805?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13864946#comment-13864946

Bryan Pendleton commented on DERBY-4805:
----------------------------------------

FWIW, all my database names have always been 10-20 characters long, max; 
I've never felt the need to have a database name which is dozens or hundreds
of characters long.

I'm not saying that raising the limit is a bad thing, but I also think that the
limit doesn't need to be absurdly large, a few hundred characters seems like
it would be plenty to me.

> Currently, whenever the client driver is used, there is a limit of 255 bytes for the
database name. This is defined by the DRDA spec and there has been a discussion on the list
[1]/[2] as to whether this limit should be raised due to the introduction of the new ACR that
allows for UTF-8 characters.
> UTF-8 characters can take up to four bytes and this reduces the limit in characters dramatically.
> This should be an easy change as there is a codepoint that defines this limit.
> [1] did not work but [2] did
