 | | | Cannot read datafile after successful recovery | Cannot read datafile after successful recovery 2005-02-17 - By Sami Seerangan
Environment: 9i RAC , 2 Node veritas cluster
One of the datafile got corrupted in test environment and restored
form RMAN backup.
However even after recovery it gave me "ORA-01187 (See ORA-01187.ora-code.com): cannot read from
file 7 because it failed verification tests"
Then I did log switch few times, then it started working.
What could be wrong here?
Thanks in advance.
