Hi All,

We are using the following commands to take hot backup of our RAC database. Hot backup is fired by "backup" user on Linux system.

rman target / nocatalog <<EOF
run {
allocate channel oem_backup_disk1 type disk format '$backup_dir/$date/%U';
#--Switch archive logs for all threads
sql 'alter system archive log current';
backup as COMPRESSED BACKUPSET database include current controlfile;
#--Switch archive logs for all threads
sql 'alter system archive log current';
#--Backup Archive logs and delete what we've backedup
backup as COMPRESSED BACKUPSET archivelog all not backed up delete all input;
release channel oem_backup_disk1;
allocate channel for maintenance type disk;
delete noprompt obsolete device type disk;
release channel;
Due to which after command (used 2 times) "sql 'alter system archive log current';" I see the following lines in alert log 2 times. Because of this all the online logs are not getting archived (Missing 2 logs per day), the backup taken is unusable when restoring. I am worried about this. I there any to avoid this situation.

Errors in file /u01/oracle/admin/rac/udump/rac1_ora_3546.trc:
ORA-19504: failed to create file "+DATA/rac/1_32309_632680691.dbf"
ORA-17502: ksfdcre:4 Failed to create file +DATA/rac/1_32309_632680691.dbf
ORA-15055: unable to connect to ASM instance
ORA-01031: insufficient privileges

I don't see the relation between your backup script and your error.
I don't understand why you say you have something missing in your backup.
If there is no error during the backup this one is complete and allow you to restore the database.
Your problem is not clear.
