OCI-45181
polling found duplicate file name string
Cause
The given file name has already been included in a storage location. There are three possible reasons for this warning.
- Two databases are contributing to the same polling location
but their format does not include the DBID.
- A backup command did not specify a unique format name.
- Recovery has restored an archived log into that location.
This is possible when the polling location is the primary archive log destination.
Action
If the cause is name formatting, then fix the formatting and rename the specified files. Polling will then find them again and include them. If this was recovery, and the files are true duplicates, delete the files. Note that the DELETE_INPUT option will not help with these duplicate files because they were not copied.
