Subject [jira] [Commented] (DERBY-6350) Provide a rolling file implementation of derby.log
Date Thu, 14 Nov 2013 19:45:22 GMT

    [ https://issues.apache.org/jira/browse/DERBY-6350?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13822812#comment-13822812
] 

Myrna van Lunteren commented on DERBY-6350:
-------------------------------------------

I did some simple manual experimenting, and did not see an empty derby.log created. But I
do see it when running the ErrorStreamsTest. I'll do a little more analysis, and if I figure
out what the problem is I'll log a new issue.
But I think this can be resolved.

> By default, derby.log grows without bounds if the derby.infolog.append property is set
to "true".   Setting this to "true" helps in a hands off production environment to ensure
that if Derby restarts, the derby.log which might contain important information is not lost.
 On the other hand, when set the "true" the derby.log grows without bounds.  This is problematic
in a long running system.  
> What is really needed is the ability to have a rolling derby.log file support where the
maximum file size and maximum number of files can be specified.  Derby has the ability to
configure the location of the log file (ie. derby.stream.error.file) and also two methods
of redirecting the error stream (.ie derby.stream.error.method and derby.stream.error.field).
 There is no standard implementation that supports a rolling derby.log however.
> This facility should be part of the core Derby system so that it works in both embedded
and network server models.
