DBA's
I'm trying to clone a database using an RMAN disk backup. The restore is
failing with:
Hex dump of (file 84, block 1) in trace file
/u02/oracle/admin/prac/udump/prac1/prac1_ora_357178.trc
Corrupt block relative dba: 0x00000001 (file 84, block 1)
Completely zero block found during deleting datafile copy
Reread of blocknum=1, file=/dev/rprac_0128_065. found same corrupt data
Reread of blocknum=1, file=/dev/rprac_0128_065. found same corrupt data
Reread of blocknum=1, file=/dev/rprac_0128_065. found same corrupt data
Reread of blocknum=1, file=/dev/rprac_0128_065. found same corrupt data
I've tried this on the files without any luck: dd if=/dev/zero
of=/dev/rprac_0128_065 bs=512 count=2 conv=notrunc
The raw's are newly created and have the correct ownership and permissions. If
I clone from a tape backup it works normally.
Thanks
