Home -> Community -> Mailing Lists -> Oracle-L -> RE: Recovery -- Can't place tablespace offline ?
To do a tablespace point in time recovery, you have to recover the
tablespace to a clone database and export the necessary data and import it
to the live database. You can't do recovery to a live database as far as I
know. At least that was what I have always believed.

Subject: Recovery -- Can't place tablespace offline ?
Hi List,
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.
