Check DB Error

Hi,

We are having standby(DRS) server for our production.

We have switch over to standby server. After running check DB we have faced the follwoing error :

BR0301E SQL error -1187 at location BrTspListGet-21

ORA-01187: cannot read from file 255 because it failed verification tests

ORA-01110: data file 255: '/oracle/R3P/sapdata1/temp_3/temp.data3'.

Our oracle version is 9.2.0.8 on AIX.

The data file 255 is existing with proper permissions.

Kindly suggest.

Regards,

Rahul.
