I have a JNI interface I wrote... for the same problem. So basically, you
access a set of classes that correspond to the Java code... would you like
that?
Or -- why not have an "Initialize()" method in ONE of the DLL's then
all of the others can call Initialize(), which should only init the
Log4CXX once?

Why don't you simply create a singleton instance of a class that will
"manage" log4cxx for you?
Then you can just query the singleton to see if it is initialized or
not... or even just call the "init()" method of the singleton in all your
DLL's... so the init
Since Log4CXX has a wire format that is compatible, you can download
Log4J... it has a SimpleSocketServer. We use it for centralizing the
logs into one file as well.

folks will look at
syslog entries -- and if the appender or logger framework were to log
something they'd see it. The more 'process' oriented companies will have
their NOC's review the logs and trap major issues as soon as they happen.

I agree wholeheartedly
If it gets into something like the scenario mentioned below, maybe the
logger can put a syslog entry, or console/stderr output (as configured by
the user in some global setting)?

We've had the exact same requirement on platform we did, which used
Log4j... and ended up running the included "SocketServer" app and then
logging everything to the socket-server, which actually wrote out the
combined file.

(maybe there was a "cd a/b/c" in the batch file that started it) and the
logs directory is in b/logs, then you need to write your path as "../logs"

Do you have a "log" subdirectory under the 'current working directory' of
your web-app? We find it best to give the full path, as we use Log4J in a
sumilar situation.

We've seen this also on Solaris and using some commercial memory-test

We've using 0.9.7 -- a modified version. If you're interested, you can try
it out on VC++ and see if it works for you.

Another option:
1. Setup a SocketAppender in the process to send logs to a "log server"
process
2. Create a "logserver" that then logs the data to file -- so you get a
single file.

3. After a certain timeout, destroy the logger -- so if no requests are
received from a client in lets say 5 minutes, the logger expires

I had actually hit the same snag in Log4J, i.e. multiple instances of the
same app. My solution was to create a "JavaHelper" native lib, which
allows me to get the process id. Then using that I enhanced the
DailyRollingFileAppender to support a %P in the filename for process id.

Yes... we're using it in a production environment... with no identifiable problems (except the time-stamp). There is a strange core dump we keep having, but because we use an in-memory database and an active/standby setup ... that's transparent to system operation.
