Gap in logs are too far to recover. Need to start over I think.

Question

Hello,
I have a dataguard setup and due to several circumstances the connection was lost to the standby and the archivelogs are gone for as far back as needed.
I want to double check that this is the best method to get synched up again. On primary I am running rman backups every night. Here is my config....
Oracle 10.2.0.5 (64 bit)
Red Hat 5 enterprise 64 bit.
PRIMARY
CONFIGURE RETENTION POLICY TO RECOVERY WINDOW OF 1 DAYS;
CONFIGURE BACKUP OPTIMIZATION ON;
CONFIGURE DEFAULT DEVICE TYPE TO DISK; # default
CONFIGURE CONTROLFILE AUTOBACKUP ON;
CONFIGURE CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE DISK TO '%F'; # default
CONFIGURE DEVICE TYPE DISK BACKUP TYPE TO COMPRESSED BACKUPSET PARALLELISM 3;
CONFIGURE DATAFILE BACKUP COPIES FOR DEVICE TYPE DISK TO 1;
CONFIGURE ARCHIVELOG BACKUP COPIES FOR DEVICE TYPE DISK TO 1; # default
CONFIGURE MAXSETSIZE TO UNLIMITED; # default
CONFIGURE ENCRYPTION FOR DATABASE OFF; # default
CONFIGURE ENCRYPTION ALGORITHM 'AES128'; # default
CONFIGURE ARCHIVELOG DELETION POLICY TO NONE; # default
CONFIGURE SNAPSHOT CONTROLFILE NAME TO '/u04/flash_recovery_area/snapcf_bcso.f';
Standby
CONFIGURE RETENTION POLICY TO RECOVERY WINDOW OF 28 DAYS;
CONFIGURE BACKUP OPTIMIZATION ON;
CONFIGURE DEFAULT DEVICE TYPE TO DISK; # default
CONFIGURE CONTROLFILE AUTOBACKUP ON;
CONFIGURE CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE DISK TO '%F'; # default
CONFIGURE DEVICE TYPE DISK BACKUP TYPE TO COMPRESSED BACKUPSET PARALLELISM 4;
CONFIGURE DATAFILE BACKUP COPIES FOR DEVICE TYPE DISK TO 1;
CONFIGURE ARCHIVELOG BACKUP COPIES FOR DEVICE TYPE DISK TO 1; # default
CONFIGURE MAXSETSIZE TO UNLIMITED; # default
CONFIGURE ENCRYPTION FOR DATABASE OFF; # default
CONFIGURE ENCRYPTION ALGORITHM 'AES128'; # default
CONFIGURE ARCHIVELOG DELETION POLICY TO NONE; # default
CONFIGURE SNAPSHOT CONTROLFILE NAME TO '/u04/flash_recovery_area/snapcf_bcso.f';
Backup script that is only run on primary. No backup on standby at the moment.
run{
crosscheck archivelog all;
delete expired archivelog all;
backup database plus archivelog not backed up delete all input;
delete noprompt obsolete;
#Fix for bug 964522.1
delete force archivelog until time 'trunc(sysdate-1)' backed up 1 times to device type disk;
So can I just copy over my flash_recovery_area to the standby FRA, restore database, recover database? Then set my log_archive_dest_2 on the primary and ALTER DATABASE RECOVER MANAGED STANDBY DATABASE DISCONNECT; on the standby?
I did not set this up initially and I see a couple issues I need to address on the standby
db_recovery_file_dest string /u01/app/oracle/flash_recovery_area
standby_archive_dest string /u04/flash_recovery_area
Here is primary
db_recovery_file_dest string /u04/flash_recovery_area
What I'm not sure of is which one of these I need to switch on the standby or in RMAN on the standby. RMAN is going to look for the backup in the location set by db_recovery_file_dest on the standby for the files to recover. I don't have room on that drive so can I just simply change on standby db_recovery_file_dest = '/u04/flash_recovery_area' for the recovery then set it back when it's finished?
Thanks

Hello again;
Monday is meeting day here.
PRIMARY
db_name='bcso'
db_unique_name='bcso'
log_archive_config='DG_CONFIG=(bcso,stdby)'
log_archive_dest_1='LOCATION=USE_DB_RECOVERY_FILE_DEST VALID_FOR=(ALL_LOGFILES,ALL_ROLES) DB_UNIQUE_NAME=bcso'
log_archive_dest_2='SERVICE=BCSTDBY_40 LGWR ASYNC VALID_FOR=(ONLINE_LOGFILES,PRIMARY_ROLE) DB_UNIQUE_NAME=stdby'
FAL_SERVER=bcso
FAL_CLIENT=stdby
STANDBY
db_name='bcso'
db_unique_name='stdby'
log_archive_config='DG_CONFIG=(bcso,stdby)'
log_archive_dest_1='LOCATION=USE_DB_RECOVERY_FILE_DEST VALID_FOR=(ALL_LOGFILES,ALL_ROLES) DB_UNIQUE_NAME=stdby'
log_archive_dest_2='SERVICE=bcso LGWR ASYNC VALID_FOR=(ONLINE_LOGFILES,PRIMARY_ROLE) DB_UNIQUE_NAME=bcso'
FAL_SERVER=stdby
FAL_CLIENT=bcso
I just want to be clear that in *.log_archive_dest_2='SERVICE=BCSTDBY_40 I put the tnsnames.ora entry of the server I want to connect to not the instance name?Correct. The is the TNSNAMES.ORA entry.
Important
The way I show it you need to set DB_RECOVERY_FILE_DEST too.
Example
db_recovery_file_dest='/u04/flash_recovery_area'
If the standby site's FRA is different you need to account for that.
Once you get it going keep this query ( I would run once a day )
