Subject [jira] [Commented] (DERBY-5526) on upgrade from 10.5 to 10.8.2 , getting ERROR XBM0A: The database directory 'C:\cygwin\home\debugfat\clientdb' exists. However, it does not contain the expected 'service.properties' file.

    [ https://issues.apache.org/jira/browse/DERBY-5526?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13165653#comment-13165653
] 

Kathey Marsden commented on DERBY-5526:
---------------------------------------

Looking at the code where vetService() is called:

 else
                                {
                                    vetService( storageFactory, name );
                                    throw StandardException.newException(SQLState.SERVICE_DIRECTORY_EXISTS_ERROR,
                                                                         getDirectoryPath(
name));
                                }


 and the issue comments for DERBY-4589, I think the intention of the new error was to just
produce a more sensible message for a half created database, but to keep the old error message
for directories not related to Derby.  I am thinking it would make sense for vetService to
check both that service.properties doesn't exist *and* seg0 does exists to determine if that
is the state of affairs.  I will give that a try on the empty directory case.

   I don't see any release note associated with DERBY-4589.  I will test an existing database
scenario with 10.5 vs 10.8., vetService just checks that service.properties exists.

>        already exists.
