To avoid guessing I'd want the alert.log and the output of the rman session. I have a guess and a question all the same.. Guess: Because RMAN knows it doesn't need to because the archivelog itself is already on disk - not deleted. The alert.log shows this message I believe. Question: What does crosscheck archivelog (from sequence 4842) give? regards On Thu, May 20, 2010 at 10:41 AM, Howard Latham <howard.latham@xxxxxxxxx>wrote: > 10g On Redhat. > > > I expect its obvious but Why cant I restore some archivelogs that are in my > db catalog and the backup pieces are present on disk. > No error messages plus no mention of the one I want when I do a restore > archivelog from sequence 4842 > Any Ideas folks? > > -- > Howard A.
