- Cautionary note
-
When log records in a log file are wrapped around to the next file, the original file is not deleted but is overwritten with new log records from the top of the file. To distinguish between log records output before and after wrapping around, the following character string (endpoint identifier) is output at the end of the latest log record.
----------< End of Data >----------
The endpoint identifier that is output at the end of the previous log is deleted, and the endpoint identifier is output again after a new log is output. Therefore, note the following points when referencing a job execution history log file:
-
To check the latest log data, reference the log data preceding the endpoint identifier. The log data that follows the endpoint identifier is the log records output before wrapping around.
-
If the log records in a log file have been wrapped around in special timing, two or more endpoint identifiers might remain in the job execution history log file. In such a case, the first endpoint identifier counted from the top of the file is valid.
