Backup of database on 11.2.0.3 problem

Question

hi,
i have database running in 11.2.0.2 on linux 5. the database is on no-arcvhive mode. I am trying to take the cold backup from rman script but the problem comes when the script tries to start database in mount but it says the the service identifier or listener does not know service is running:
rman target sys/pws@dbname <<EOF
spool log to /tmp/backup.log
run {
ALLOCATE CHANNEL t1 DEVICE TYPE DISK FORMAT '/location/db_%d_%u_%s_%T';
sql 'ALTER SYSTEM FLUSH SHARED_POOL';
shutdown immediate;
startup mount;
backup Database format '/location/%d_FULL_%u_%s_%T.bck';
alter database open;
backup current controlfile;
sql 'ALTER DATABASE BACKUP CONTROLFILE TO TRACE';
release channel t1;
what i am doing wrong?

Hi,
By default, the PMON process registers service information with its local listener on the default local address of TCP/IP, port 1521. If the listener configuration is synchronized with the database configuration, then PMON can register service information with a nondefault local listener or a remote listener on another node. Synchronization occurs when the protocol address of the listener is specified in the listener.ora file and the location of the listener is specified in the initialization parameter file.
After Shutdown Database the Default Service Name is removed from Listener as you are connecting remotely on Database using TNSNAMES the service must be registered statically on Listener.
Configuration of static service information is necessary if you require remote database startup from a tool (like RMAN).

Why you are executing "sql 'ALTER SYSTEM FLUSH SHARED_POOL';" during backup ? (just curious)
