Dear sir,

We are taking full backup and incremental level bkp thro RMAN using below script
now we need to test the recovery part.....

script1:(full backup)
----------------------
RMAN> CONNECT TARGET *
2> run {
3> allocate channel 'dev_0' type 'sbt_tape'
4> parms 'ENV=(OB2BARTYPE=Oracle8,OB2APPNAME=SBIWILL1,OB2BARLIST=SBIWILL1_THU_Incr1,OB2BARHOSTNAME=cmpdb1)';
5> allocate channel 'dev_1' type 'sbt_tape'
6> parms 'ENV=(OB2BARTYPE=Oracle8,OB2APPNAME=SBIWILL1,OB2BARLIST=SBIWILL1_THU_Incr1,OB2BARHOSTNAME=cmpdb1)';
7> allocate channel 'dev_2' type 'sbt_tape'
8> parms 'ENV=(OB2BARTYPE=Oracle8,OB2APPNAME=SBIWILL1,OB2BARLIST=SBIWILL1_THU_Incr1,OB2BARHOSTNAME=cmpdb1)';
9> allocate channel 'dev_3' type 'sbt_tape'
10> parms 'ENV=(OB2BARTYPE=Oracle8,OB2APPNAME=SBIWILL1,OB2BARLIST=SBIWILL1_THU_Incr1,OB2BARHOSTNAME=cmpdb1)';
11> backup incremental level 0
12> format 'SBIWILL1_THU_Incr1<SBIWILL1_%s:%t:%p>.dbf'
13> database;
14> backup
15> format 'SBIWILL1_THU_Incr1<SBIWILL1_%s:%t:%p>.dbf'
16> current controlfile;
17> }
18> EXIT

script2( for incremental level 1 )
----------------------------------

RMAN> CONNECT TARGET *
2> run {
3> allocate channel 'dev_0' type 'sbt_tape'
4> parms 'ENV=(OB2BARTYPE=Oracle8,OB2APPNAME=SBIWILL1,OB2BARLIST=SBIWILL1_THU_Incr1,OB2BARHOSTNAME=cmpdb1)';
5> allocate channel 'dev_1' type 'sbt_tape'
6> parms 'ENV=(OB2BARTYPE=Oracle8,OB2APPNAME=SBIWILL1,OB2BARLIST=SBIWILL1_THU_Incr1,OB2BARHOSTNAME=cmpdb1)';
7> allocate channel 'dev_2' type 'sbt_tape'
8> parms 'ENV=(OB2BARTYPE=Oracle8,OB2APPNAME=SBIWILL1,OB2BARLIST=SBIWILL1_THU_Incr1,OB2BARHOSTNAME=cmpdb1)';
9> allocate channel 'dev_3' type 'sbt_tape'
10> parms 'ENV=(OB2BARTYPE=Oracle8,OB2APPNAME=SBIWILL1,OB2BARLIST=SBIWILL1_THU_Incr1,OB2BARHOSTNAME=cmpdb1)';
11> backup incremental level 1
12> format 'SBIWILL1_THU_Incr1<SBIWILL1_%s:%t:%p>.dbf'
13> database;
14> backup
15> format 'SBIWILL1_THU_Incr1<SBIWILL1_%s:%t:%p>.dbf'
16> current controlfile;
17> }
18> EXIT

Now we need to test the recovery, i.e. we need to recover both this full bkp and incr.bkp.
how to recover ?

shall we write this below script ?

RMAN> STARTUP MOUNT;
RMAN> RESTORE DATABASE;
RMAN> RECOVER DATABASE;
RMAN> ALTER DATABASE OPEN;

and adv us how to recover this incremental backup ..

thank you,
kesavan.

You don't need to do anything special. RMAN keeps track of all the backups (full and incremental) and will know what to restore. Just code your RESTORE and RECOVER statements as you would normally do.

I thinkg kesavansundaram meant that "How do I know about exactly what incremental level when I run restore/recovery command?"

No! His question was "how to recover?". Please re-read his original post. If that is what he meant, he can tell us himself.
