Subject [jira] [Commented] (DERBY-4805) Increase the length of the RDBNAM field in the DRDA implementation
Date Mon, 10 Feb 2014 14:58:22 GMT

    [ https://issues.apache.org/jira/browse/DERBY-4805?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13896627#comment-13896627
] 

Knut Anders Hatlen commented on DERBY-4805:
-------------------------------------------

InternationalConnectTest fails on Solaris now if the underlying file system is UFS. The problem
appears to be that UFS doesn't allow path names that are longer than 1024 characters. The
path name used in the test is shorter than that, but it's a relative path name, so it may
get longer than 1024 characters after it has been canonicalized.

> 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
