Optionally, set the LOG_ARCHIVE_FORMAT initialization parameter, using %t to include the thread number as part of the file name, %s to include the log sequence number, and %r to include the resetlogs ID (a timestamp value represented in ub4). Use capital letters (%T, %S, and %R) to pad the file name to the left with zeroes.

Note:If the COMPATIBLE initialization parameter is set to 10.0 or higher, the database requires the specification of resetlogs ID (%r) when you include the LOG_ARCHIVE_FORMAT parameter. The default for this parameter is operating system dependent. For example, this is the default format for UNIX:
The incarnation of a database changes when you open it with the RESETLOGS option. Specifying %r causes the database to capture the resetlogs ID in the archive log file name, enabling you to more easily perform recovery from a backup of a previous database incarnation. See Oracle Database Backup and Recovery Advanced User's Guide for more information about this method of recovery.

I was able to modify the script to add the resetlog_id from the v$archived_log to move them to Tivoli when they are already "archived" combining the script with the v$log.
