How you guys do this ? finding the latest thread and applying recovery

Question

hi guys,
i am doing a bash script and i need to do know the latest arch log sequence every archived.
to know the latest arch log
i) either get the max(seq#) from v$archived_log
or
ii) i can go to the arch folder and get the one with the latest date.
however,
how do i get that value out and apply it in rman ?
Inside my rman script, i have got this..
recover database until sequence xxxx;
how do i fill in the value 'xxxx' ? with the latest archived log in the database ?
please advise
regards,
Noob

Answer 1

V$LOG_HISTORY to view the redo logs that you have archived.
Perform an incomplete recovery until log sequence number 6 on thread 1:
run {
set until logseq 6 thread 1;
allocate channel ch1 type 'sbt_tape';
restore database;
recover database;
alter database open resetlogs;
reset database;
back up the database for new incarnation
run {
allocate channel ch1 type 'sbt_tape';
backup database;
}
