ARCHIVE logs are being deleted before they are backed up. This is happening in 4 of our RAC production databases and they are on different RAC servers.
The databases are part of a Data Guard configuration and all the archive logs are shipped. The archive logs that were not not backed up can be identified by running below query. This example will focus on thread=2 and sequence=111612
