Refer to Checking Logical-Log Backup Result with Activity Log.

Each request also writes a log file in the directory current at the time the request is started. You request logging with the LOG qualifier or you can set it up as a default in the oper_deflt.arc file. If the request ID is 203, then the name of the log file is arc00000203.log .

You should periodically check your email for notification of database archive (and logical-log backup) request status. You only receive email if you use the NOTIFY qualifier in your request or specify NOTIFY in the oper_deflt.arc file.

As mail is sent to the user informix or <sid>adm (depending on the user who started the archive), it is best to have the mail automatically forwarded to the mailbox of a database administrator.
