Hi all,

When I do

SELECT name from v$datafile;

NAME

...
/disk1/Oracle8i/dbs/MISSING00007
/disk1/Oracle8i/dbs/MISSING00008

Where are these files came from ?

do I lost anything ?

When I quickly do ALTER DATABASE BACKUP CONTROLFILE TO TRACE;

Why the trace file is not generated at my udump (according to my init.ORA setting)
It generated at
/disk1/Oracle8i/rdbms/log/*.trc (which is not my user_dump_dest path)

and this file contain

CREATE CONTROLFILE
...

DATAFILE

        '/disk1/Oracle8i/system01.dbf',
        ...
        '/disk1/Oracle8i/dbs/MISSING00007',
        '/disk1/Oracle8i/dbs/MISSING00008'

;

ALTER DATABASE DATAFILE '/disk1/Oracle8i/dbs/MISSING00007' OFFLINE; ALTER DATABASE DATAFILE '/disk1/Oracle8i/dbs/MISSING00008' OFFLINE;

Thank you,

Sinardy

The answer lies on Page 563 of Oracle SQL Reference manual from oraprd5 docu cd rom.

The steps are:

Take full offline database (data files) backup just in case
Use svrmgrl to "startup nomount"
Issue the create control file command for example:

CREATE CONTROLFILE REUSE DATABASE "TDBA" NORESETLOGS NOARCHIVELOG

MAXLOGFILES 100          MAXLOGMEMBERS 10        MAXDATAFILES 1000
MAXINSTANCES 2         MAXLOGHISTORY 500
LOGFILE
          GROUP 1 '/u1/......dbf'  SIZE 64M,
          GROUP 2 '...
          GROUP 3 ..
          GROUP N..
DATAFILE
          '/u2/.dbf' SIZE xM,
          '/u2/.dbf' SIZE xM,
          '/u2/.dbf' SIZE xM
          .....;

Note that we must use unix FIND command to search all the above files for names and sizes.
4. Recover database (for safe side)
5. alter database open.
