I am writing log entries into a log file using the JadeLog class. I would like to force Jade to release the locks on the file or to roll over to a new log file.

Does anyone know how I could get Jade to do either of these?

Thanks

Torrie,
In Jade 6 there is a rollOverLog method on JadeLog, but it sounds like you are using Jade 5.2 in which case you may be stuffed.

Torrie,

You have to do something like this method that we use:

logMessage(s:String) updating;
/* Uses the JadeLog class to write a message to msg<n>.log */begin

if msgLog=null then
create msgLog;
msgLog.fileName:="msg";
msgLog.formatOutput:=false;
// msgLog.maxFileSize:=1000; // leave commented out to use value from ini file - doesn't work - Jade bug
msgLog.maxFileSize:=app.getProfileStringAppServer(app.getIniFileNameAppServe r,"JadeLog","MaxLogFileSize","1000000").Integer;
endif;
msgLog.log(actualTimeAppServer.logFormat&" "
&name&"/"&cnGetInstanceId(process).String&": "
&s&CrLf);
// delete msgLog;
end;

As I recall, to release (unlock) the file, you have to delete the JadeLog instance. We don't run this way. To get it to "version" correctly, you have to explicitly set msgLog.maxFileSize. The above code reads the current .ini file to get the appropriate value. This works in 5.2.
