At opening bases there is a message:
ORA-01157: cannot identify/lock data file 30 - see DBWR trace file
ORA-01110: data file 30: '/odb5/TRM/tools_01.dbf '

my actions:
SVRMGR > alter database datafile '/odb5/TRM/tools_01.dbf ' offline;
Statement processed.
SVRMGR > alter database open;
Statement processed.
SVRMGR> host
[oracle@trm odb2]$ cp /backup/odb5/TRM/tools_01.dbf /odb5/TRM/tools_01.dbf
[oracle@trm odb2]$ exit
SVRMGR > recover automatic datafile /odb5/TRM/tools_01.dbf ';
ORA-00283: recovery session canceled due to errors
ORA-01157: cannot identify/lock data file 30 - see DBWR trace file
ORA-01110: data file 30: '/odb5/TRM/tools_01.dbf'

cp /backup/odb5/TRM/tools_01.dbf /odb5/TRM/tools_01.dbf

Did your file copy correct ? I mean within directory(/odb5/TRM/) or directory where you want it to be.

Check for the file permissions and ownership for the datafile.  The file should be read-writeable and owned by oracle:dba.

Also post the Oracle errors from your DBWR trace file.

in addition to Allahabad and ramkb, check if there is a bad sector in disk.
