A new z/OS (OS/390) Specific Rolling File Appender.

           Summary: A new z/OS (OS/390) Specific Rolling File Appender.
           Product: Log4j
           Version: unspecified
          Platform: Other
        OS/Version: Other
            Status: NEW
          Severity: Enhancement
          Priority: Other
         Component: Appender
        AssignedTo: log4j-dev@jakarta.apache.org
        ReportedBy: mike_nitso@hotmail.com


Typically, we do not have the ability to create dynamic file names for output 
in the log4j.properties file. Quality of service dictates that the z/OS 
environment will create and destroy servant regions in order to balance load.  
Since each of these servant regions will read a single log4j.properties file, 
they each will be logging to the same output file, as specified in the 
log4j.properties file.  Having multiple servant regions log to the same file 
will result in lost log statements (only on z/OS), and file contention 
(creating reduced performance for a particular servant region).  Hence, this 
appender will generate a unique file name to log to per servant region.  This 
appender also supports the PropertyConfigurator.configureAndWatch() method 
since the dynamic file name is created the same way each time.  Therefore, any 
updates made to the log4j.properties file will be realized, and the dynamic 
file name will not be changed.
