The log_archive_format parameter is set to %t_%s_%r.dbf,but the archive log is generate as o1_mf_1_10_7x6lby27_.arc, why?


SQL> show parameters log_archive_format;

------------------------------------ ----------- ------------------------------
log_archive_format                   string      %t_%s_%r.dbf

Thanks,
The reason maybe is the parameters LOG_ARCHIVE_DEST is set to null, can you confirm?

Oracle Doc Say:
The string generated from this format is appended to the string specified in the LOG_ARCHIVE_DEST parameter

It is because you are archiving to the Fast Recovery Area, using Oracle Managed Files. So Uncle Oracle takes over the file naming.
