I'm using the DailyRollingFileAppender (DRFA) from the most recent stable
log4j release. The application runs under Win2K in TomCat.
When I run the class in my IDE (netbeans), the DRFA works fine (except when
noted below). When the class is run in Tomcat (being called via a JSP
page) it usually "fails" (the old access.log file is overwritten with a new
access.log and no backup was created).
I've found that if I run the class under Forte and keep it running (the
process doesn't end) and then run a second instance (separate process) of
the class, the DRFA will not rename the file (giving a can't rename
message).
log4j:ERROR Failed to rename [E:\vns\access.log] to
[E:\vns\access.log.2002-11-12-11-53].
It appears that there's an issue here between "who" has the rights to the
file under Win2K. As long as process A is still running, when process B
sends a log event (log.info()) which would require the DRFA to rollover, it
cannot rename the file under Win2K because it is "open" by process A, even
though process B uses the same DRFA as process B does. Does this make any
sense or is there something else going on here?
