They cannot understand why this was done. Space pressure?
There was 20% free in the FRA before, during, and after we restored the logs.
Why was Oracle automatically deleting these archivelogs that we needed?
The db_recovery_file_dest_size is correct and matches the disk group size perfectly.

 

Changes

They had restored some archivelogs that had been deleted, as a the Goldengate product needed them.
After restoring the archivelogs they needed, they  noticed that the +FRA diskgroup was still at 20% free.

All of the requested logs were now on disk again.  Later, though, when trying to access some of the
very same restored archivelogs, they found they had been mysteriously deleted.
