Getting error when try to backup oracle rac to another location

Question

Hi there,
I am attempting to backup database to another location from a Oracle RAC database version 11gr2. Here is my script:
#!/bin/ksh
export ORACLE_SID=vvsms1
ORACLE_BASE=/u01/app/oracle; export ORACLE_BASE
ORACLE_HOME=$ORACLE_BASE/product/11.2.0/dbhome_1; export ORACLE_HOME
BASE_PATH=/usr/sbin:$PATH; export BASE_PATH
PATH=$ORACLE_HOME/bin:$BASE_PATH; export PATH
/u01/app/oracle/product/11.2.0/dbhome_1/bin/rman target sys/viviet@vvsms log /home/oracle/log_rman/vvsms.log append <<EOF
RUN {
CROSSCHECK BACKUP;
CROSSCHECK ARCHIVELOG ALL;
ALLOCATE CHANNEL CHANNEL1 TYPE DISK FORMAT '/home/oracle/backup/vvsms/backup_%U';
BACKUP INCREMENTAL LEVEL 0 TAG 'incr_vvsms' DATABASE;
BACKUP ARCHIVELOG ALL;
DELETE OBSOLETE;
RELEASE CHANNEL CHANNEL1;
EXIT;
EOF
I write it into a .sh file and set crontab to run it. But when it run i get the error like these:
Starting backup at 22-OCT-12

I don't know what i'm wrong? The location is correct ("/home/oracle/backup/vvsms/).
Please suggest me some things about it. What do i need to do?
Thanks in advance!
P/s: Sorry for my bad English.

/u01/app/oracle/product/11.2.0/dbhome_1/bin/rman target sys/viviet@vvsms  log /home/oracle/log_rman/vvsms.log appendThis line can be your problem.
As this database is a RAC and your are using a service with load balance "vvsms" and "/home/oracle/backup/vvsms" is not a shared location. RMAN is starting a session on Other node where "/home/oracle/backup/vvsms" does not exists.
Try change it :
/u01/app/oracle/product/11.2.0/dbhome_1/bin/rman target sys/viviet@vvsms  log /home/oracle/log_rman/vvsms.log appendTo this (using Easy Connect Method):
/u01/app/oracle/product/11.2.0/dbhome_1/bin/rman target sys/viviet@localhost:1521/VVSMS  log /home/oracle/log_rman/vvsms.log appendWhere:
localhost: your local node
VVSMS : is the service of database
Also check if "/u01/app/oracle/product/11.2.0/dbhome_1/network/admin/sqlnet.ora" have configured the line "NAMES.DIRECTORY_PATH= (TNSNAMES, EZCONNECT)"
P.S : When RMAN start a session it show where is logged, check on logs what instance RMAN was logged.
