My doubt is why it show each sequence twice. What is the meaning for this? Please help me.
Database Version 11gr2

Answer 1

Yes i have standby database. Because of this it showing two. Am i right?
I think for each sequence, one archive is applied-->log file move to standby and applied
another archive is not appiled-> because it generated and saved in its own location
Am i right??yes, it shows for copy according to each DESTINATION
SQL> select dest_id, name from v$archived_log where thread#=1 and sequence#=2487;
