ORA-01114 file$ now showing corresponding file

Question

We are getting following errors in alert log
ORA-01114: IO error writing block to file 557 (block # 230471)
ORA-27072: skgfdisp: I/O error
ORA-01114: IO error writing block to file 557 (block # 230471)
ORA-27072: skgfdisp: I/O error
I ran following sql
SELECT tablespace_name, segment_type, owner, segment_name
FROM dba_extents
WHERE
file_id = 557 AND
230471 between block_id AND block_id + blocks - 1;
This shows 0 rows selected.
V$datafile and v$tempfile does not have have any entry for 557.
File$ has 258 records.
V$datafile has -194 records.
V$tempfile has - 007 records.
V$log has -004 records.
V$control has -003 records.
50 records. – Why file$ is showing 50 more records ?
Executed following sql
select a.file#,a.rfile#,b.file#,b.relfile# from
v$datafile a, file$ b
where a.file#(+)=b.file#
and a.rfile#(+)=b.relfile#
and a.ts#(+)=b.ts#;

Answer 1

Some questions:
1. OS type?
2. File System type? Check the size of datafile #557 and check the FS limits.
4. Are there entries when you issue following command "select * from v$recover_file"?
5. Did you check the file permissions? (Oracle owner must have write permission)
