Tablespace Complete Restore problem.

Question

Hi Team,
I am working on the Oracle 9i tablespace backup & restore operation.
For backup I am using the following script.
run
BACKUP TABLESPACE 'CWMLITE' INCLUDE CURRENT CONTROLFILE FORMAT 'C:\BK\CWMLITE_%d_01';
BACKUP TABLESPACE 'DRSYS' INCLUDE CURRENT CONTROLFILE FORMAT 'C:\BK\DRSYS_%d_01';
Now when I restore back the above tabalespaces using script.
run
SQL 'ALTER TABLESPACE "CWMLITE" ONLINE';
SQL 'ALTER TABLESPACE "DRSYS" ONLINE';
SQL 'ALTER TABLESPACE "CWMLITE" OFFLINE IMMEDIATE';
SQL 'ALTER TABLESPACE "DRSYS" OFFLINE IMMEDIATE';
restore tablespace 'CWMLITE' , 'DRSYS' ;
recover tablespace 'CWMLITE' , 'DRSYS' ;
SQL 'ALTER TABLESPACE "CWMLITE" ONLINE';
SQL 'ALTER TABLESPACE "DRSYS" ONLINE';
it gives me following prompts as
either readonly, offline, or already restored...
As following....
using target database controlfile instead of recovery catalog
sql statement: ALTER TABLESPACE "CWMLITE" OFFLINE IMMEDIATE
sql statement: ALTER TABLESPACE "DRSYS" OFFLINE IMMEDIATE
Starting restore at 13-DEC-06
allocated channel: ORA_DISK_1
channel ORA_DISK_1: sid=11 devtype=DISK
skipping datafile 3; already restored to file C:\NEW\ORADATA\ITPL\CWMLITE01.DBF
skipping datafile 4; already restored to file C:\NEW\ORADATA\ITPL\DRSYS01.DBF
restore not done; all files readonly, offline, or already restored
Finished restore at 13-DEC-06
Starting recover at 13-DEC-06
using channel ORA_DISK_1
starting media recovery
media recovery complete
Finished recover at 13-DEC-06
sql statement: ALTER TABLESPACE "CWMLITE" ONLINE
sql statement: ALTER TABLESPACE "DRSYS" ONLINE
But If I run the same script once again it works & will not prompts me the readonly, offline, or already restored & also restore the tablespaces properly
RMAN> run
2> {
3> SQL 'ALTER TABLESPACE "CWMLITE" OFFLINE IMMEDIATE';
4> SQL 'ALTER TABLESPACE "DRSYS" OFFLINE IMMEDIATE';
5> restore tablespace 'CWMLITE' , 'DRSYS' ;
6> recover tablespace 'CWMLITE' , 'DRSYS' ;
7> SQL 'ALTER TABLESPACE "CWMLITE" ONLINE';
8> SQL 'ALTER TABLESPACE "DRSYS" ONLINE';
9> }
sql statement: ALTER TABLESPACE "CWMLITE" OFFLINE IMMEDIATE
sql statement: ALTER TABLESPACE "DRSYS" OFFLINE IMMEDIATE

channel ORA_DISK_1: starting datafile backupset restore
channel ORA_DISK_1: specifying datafile(s) to restore from backup set

channel ORA_DISK_1: restore complete
Finished restore at 13-DEC-06
Starting recover at 13-DEC-06
using channel ORA_DISK_1
starting media recovery
media recovery complete
Finished recover at 13-DEC-06
sql statement: ALTER TABLESPACE "CWMLITE" ONLINE
sql statement: ALTER TABLESPACE "DRSYS" ONLINE
Why its behaving this strange way.
am I going wrong anywhere ? Plz suggest.

Hi ebrian,
Sorry for that additional online command.
It is not in the actual script.
The script is like only.
run
SQL 'ALTER TABLESPACE "CWMLITE" OFFLINE IMMEDIATE';
SQL 'ALTER TABLESPACE "DRSYS" OFFLINE IMMEDIATE';
restore tablespace 'CWMLITE' , 'DRSYS' ;
recover tablespace 'CWMLITE' , 'DRSYS' ;
SQL 'ALTER TABLESPACE "CWMLITE" ONLINE';
SQL 'ALTER TABLESPACE "DRSYS" ONLINE';
& still it fails at first restore , but when we execute the same script second time , it works..
plz comment,
