Subject [jira] [Commented] (DERBY-6350) Provide a rolling file implementation of derby.log
Date Wed, 02 Oct 2013 02:46:23 GMT

    [ https://issues.apache.org/jira/browse/DERBY-6350?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13783589#comment-13783589
] 

Brett Bergquist commented on DERBY-6350:
----------------------------------------

Mamta, the other properties also use "useDefaultStream".  For example, if "derby.stream.error.field"
fails, it calls "useDefaultStream", similarly if "derby.stream.error.method" fails, it calls
"userDefaultStream" and finally if "derby.stream.error.file" fails, it also calls "useDefaultStream".
 

So should this be any different?   I think if this should call "createDefautStream" then the
other methods should as well.  If not, then this should be consistent with those.  And in
any case, if specified wrong I think it will be immediately recognized and corrected.

At this point I would rather not change this but of course I will go with what ever is decided.

> 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.
