Hi List,
-------- oracle 9.2.0.4 on win2k --------
I need to try recovery scenario {case 6} in
Freeman's RMAN book. In order to simulate
datafile corruption , i decided to overwite the
database file with a small text file when the
database is open.
But later in order to recover,i am not able to
place the tablespace ( which had the datafile )
offline. Doing so , i get the error :
ORA-01115 : IO error reading block from file 5 (block #1)
ORA-01110 : datafile 5 : 'd:\indx01.dbf'
ORA-27091 : skgfqio: unable to queue I/O
ORA-27070 : skgfdisp: async read/write failed
1.How do i place the tablespace offline in the above case
and proceed further with recovery when DB is OPEN ?
However , I am able to recover when the DB is mounted.
2.How to corrupt a datafile when DB is open other than
as i did ?
Regards,
Prem.
