ReplicationControl outputs the operation trace (trace log) in the folder iSMrpl\etc\trace under the
folder where ReplicationControl has been installed (\Program Files\NEC\iSMrpl\etc\trace\ by
default) to deal with faults if occur.
In operation trace files, messages output to the standard output, standard error output, event log, and
command trace and the detailed internal information are recorded. These files are used as important
data for analyzing a fault if occurs. For details of information to be collected in the event of a fault,
refer to 2.2.7 “Information Gathering in the Event of a Fault”.
The amount of the output operation trace (file size) and retention amount and period vary depending
on the command execution frequency and other factors. You can set these items optionally by
writing the following option parameters:
[TRACELOG] section
RPLLOGFILENUM
Specifies the maximum number of log files to be saved.
When this option parameter is omitted, up to 10 log files are used sequentially.
RPLLOGFILEMAXSIZE
Specifies the maximum size per a log file to be saved in kilobytes.
When this option parameter is omitted, the size of one log file is about 400 kilobytes.
In ReplicationControl Ver2.1 or earlier, log data recorded during the number of days specified by
option parameter RPLLOG was saved in one log file. This conventional method is not
recommended due to the following reasons:
• The saved log file becomes larger in proportion to the command execution frequency.
• When the first command is executed after change-of-day, one day’s log out of the retention
period is deleted. Therefore, if one day’s log data to be deleted is large, it takes time to
delete it.
Accordingly, if option parameter RPLLOG has been used, it is advisable to change the setting to that
using the above option parameters RPLLOGFILENUM and RPLLOGFILEMAXSIZE for operation.
