Dear all,
I have a production DB which is backed up daily including archives , and will be deleted from the server using " delete input " command after backued up.

The problem is when I tried to do restore , I faced those two error ( Rman-6053 - Rman-6025 )
--> RMAN 6053 unable to perform media recovery because of missing log
--> RMAN 6025 no backup of log thread 1 sequence 1554 lowscn ......

and when I checked the alert log file , I found thouse archives deleted ,
Deleted Oracle managed file D:\ARCHIVE\mydb\ARCHIVELOG\2012_04_26\O1_MF_1_1554_7SMBB5Y6_.ARC
Deleted Oracle managed file D:\ARCHIVE\mydb\ARCHIVELOG\2012_04_26\O1_MF_1_1555_7SMBBDQD_.AR

So how it's possible , since I have good space in the FRA

What the reasons & assumptions that deleted this file ?

If your archive logs were backuped up with RMAN you can try retoring them first with this syntax.

restore archivelog from logseq 1 until logseq 10;

You can recover groups at time and apply them until you see a message like "media recovery cancelled". That means you dont need to apply any more logs.
