1 – Validate the datafiles state:

SQL > select name from v$datafile where status = 'RECOVER';

Results:

/oracle/XXX/sapdata2/prd_14/prd.data14

2 – Do a Recover

SQL > alter database recover datafile '/oracle/XXX/sapdata2/prd_14/prd.data14';

SQL > shutdown

SQL > startup

3 – Validate at the OS Level if error is still there

#tail -100 alert_PRD.log

If the error is there:

SQL > shutdown

SQL > startup mount;

SQL > alter database datafile '/oracle/XXX/sapdata2/prd_14/prd.data14' offline;

SQL > alter database recover datafile '/oracle/XXX/sapdata2/prd_14/prd.data14';

SQL > alter database datafile '/oracle/XXX/sapdata2/prd_14/prd.data14' online;

SQL > alter database open;

4 – Useful command lines:

select substr(name,22,20) "Datafile", status from v$datafile;

select name from v$datafile where status = 'OFFLINE';

select name from v$datafile where status = 'SYSTEM';

select name from v$datafile where status = 'ONLINE';

select name from v$datafile where status = 'RECOVER';
