Subject [jira] Commented: (DERBY-4771) Continue investigation of automatic creation/update of index statistics
Date Wed, 01 Dec 2010 21:15:13 GMT

    [ https://issues.apache.org/jira/browse/DERBY-4771?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12965851#action_12965851

Kristian Waagan commented on DERBY-4771:

The only thing I can say based on the output you attached, is that it appears that the feature
has been disabled.
I think this is because of a bug I introduced when I changed the names of the properties.
Try running *without* specifying derby.storage.indexStats.auto.

I have already fixed this in my sandbox, and I'll include it in the proper version of 2f,
along with one more test and some additional changes to the tests/utilities. I'll also inculde
the value of the disable-flag in the trace line printed when the daemon is created.
