There is no table in the OMS repository that contains v$log_history or v$archivelog data for targets. There is a table that contains the datafiles for all the targets. Have a look at my blog post below where I use data in the OMS repository to get some storage reports and inventory reports.
How can I retrieve the information of rman backup details?
If you intend to get Backup détails with Oracle Enterprise Manager, the link bellow may help you:
Else, you can also do it in command line from the Server housing the Database:
rman connect target / list backup summary;
Hope this help,
Are you using Enterprise Manager to schedule your RMAN backups? If so then yes you can pull a report. If you are not using Enterprise Manager to schedule your RMAN backups but you are using an RMAN catalog you can create a DBLINK from the OMS repository to your catalog and pull a daily report.
I have designed but of these type of methods and will share once I know how you are doing the backups.
