5.1.1.  Log Daemon Specific  ConfigurationThis window controls configuration of the log daemon and the central HPSS log.
Field Descriptions
Log File Maximum Size. The maximum size in bytes of each central log file. The default value  is 
5,242,880 (5 MB). Once the maximum size is reached, logging will switch to a second log file. The log 
file that filled up will then be archived to an HPSS file if the Archive Flag is  on. Since two log files are 
allocated to accommodate log switching and log file archiving, the amount of space used by logging will 
be twice the specified value.
Switch Logfiles. A flag that indicates whether a switch to the second  log file should be performed if the 
archive of the second log file has not yet completed. Use the default value of Always. Although a log 
may not get archived, the alternative may be a loss of logged messages to the current log from running 
servers.
Daemon Port. The port number for communication between the Log Client and the Log Daemon. The 
default value is 8100. Ensure that the port number assigned does not conflict with a ny other application 
on the node. The port value must be a different value than the Client Port number in the  Log Client 
configuration entries.
Archive Logfiles. A flag that indicates whether log files should be archived when  they fill.
Archive Class of Service. When a log file exceeds Log File Maximum Size, it will be archived  to this 
class of service if the Archive Logfiles flag is set.
Log Directory. The name of the UNIX directory in which log files are stored. The default  value is 
/var/hpss/log.
5.1.2.  Migration/Purge Se rver (MPS) Specific Conf igurationThis tab of the Migration Purge Server Configuration window allows you to upda te/view the type-
specific configuration parameters for a Migration/Purge Server (MPS).
As with any other part of the server configuration, updates made here are written directl y to metadata 
with no involvement by the server. The server, if already running, must be recycled in order for the 
changes to become effective.
