Try running a dbverify command on the corrupt datafile?

Hi!

I am doing an active duplication of one test database to another one, for another group of developers. Here is what I am getting:

consistency value in tail: 0x00000001
 check value in block header: 0xb601
 computed block checksum: 0x0
Reading datafile '/U02/oradata/test2a/data21.dbf' for corruption at rdba: 0x11000001 (file 68, block 1) Reread (file 68, block 1) found same corrupt data (no logical check) Hex dump of (file 69, block 1) in trace file /app01/oracle/diag/rdbms/test2a/test2/trace/test2_ora_25016.trc Corrupt block relative dba: 0x11400001 (file 69, block 1)

It probably means that the source database is corrupt, yet there is nothing in the alert log. I will do backup validate logical, but this will take some time, since it's a database over 2TB. Does anyone have any idea how to establish whether the source DB is corrupt faster than using backup validate?
