DB STARTUP 시 ORA-312, ORA-313(ONLINE REDO LOG CRASH)
=====================================================
PURPOSE
[ ONLINE REDO LOG가 손상되었을 때 DB에 OPERATION 이 없었던 경우는 다음과 같은 절차로 DB 을 OPEN 할 수 있다. - 확률 70% ]
Explanation & Example
1. CONTROLFILE 생성
-. 손상된 online log 는 포함시키지 않는다.
-. resetlogs option 으로 생성한다.
-. reuse option 은 생략하고 기존 controlfile 은 다른 이름으로 move 시킴.
<V7 에서 CONTROLFILE 생성하는 방법 >
sqldba> startup mount
sqldba> alter database backup controlfile to trace;
위와 같이 명령을 입력하면 ORACLE_HOME/rdbms/log 디렉토리에 trace 화일이
생긴다. 그 trace 화일에서 create controlfile 명령 부분을 남기고 삭제
한다.
(7.3 이상에서는 cd $ORACLE_HOME
cd ../../admin/SID dir/udump 에 있습니다.)
콘트롤 화일 생성 문장 예 - <cnt.sql> : GROUP 1 이 ONLINE LOG 라고 가정
CREATE CONTROLFILE DATABASE "RC722" RESETLOGS NOARCHIVELOG
MAXLOGFILES 32 ********
MAXLOGMEMBERS 2
MAXDATAFILES 30
MAXINSTANCES 8
MAXLOGHISTORY 800
LOGFILE
GROUP 2 '/oracle/oracle/dbs/log2RC722.dbf' SIZE 5M,
GROUP 3 '/oracle/oracle/dbs/log3RC722.dbf' SIZE 5M
DATAFILE
'/oracle/oracle/dbs/systRC722.dbf',
'/oracle/oracle/dbs/rbsRC722.dbf',

'/oracle/oracle/dbs/tempRC722.dbf',
'/oracle/oracle/rcdata.dbf'
2.절차
$ sqldba lmode=y
SQLDBA> connect internal
SQLDBA> shutdown abort
SQLDBA> startup nomount
statement processed
SQLDBA> @cnt
SQLDBA> recover database using backup controlfile until cancel;
CANCEL (Return)
Recovery canceled
SQLDBA> alter database open resetlogs;
: 만일 정상적으로 open 되면 log file 추가
SQLDBA> alter database add logfile '?/dbs/log1ORA722.dbf' size 1M;

Answer 1

You could check if the recovery was complete by (re)creating the controlfile with the resetlogs option.
<CREATE CONTROLFILE REUSE DATABASE define_db_name RESETLOGS NOARCHIVELOG
...>Thanks for the hint. If possible, could you only check if the steps I'm going to perform are ok.
I did an "alter database backup controlfile to trace;" and then extracted the create controlfile definition part. So in essence I should run the following statements:
CREATE CONTROLFILE REUSE DATABASE "TESTDB" RESETLOGS  ARCHIVELOG
    MAXLOGFILES 16
    MAXLOGMEMBERS 3
    MAXDATAFILES 100
    MAXINSTANCES 8
    MAXLOGHISTORY 292
LOGFILE
  GROUP 1 'C:\ORADATA\TESTDB\REDO01.LOG'  SIZE 20M,
  GROUP 2 'C:\ORADATA\TESTDB\REDO02.LOG'  SIZE 20M,
  GROUP 3 'C:\ORADATA\TESTDB\REDO03.LOG'  SIZE 20M
-- STANDBY LOGFILE
DATAFILE
  'C:\ORACLE\PRODUCT\10.2.0\ORADATA\TESTDB\SYSTEM01.DBF',
  'C:\ORACLE\PRODUCT\10.2.0\ORADATA\TESTDB\UNDOTBS01.DBF',
  'C:\ORACLE\PRODUCT\10.2.0\ORADATA\TESTDB\SYSAUX01.DBF',
  'C:\ORACLE\PRODUCT\10.2.0\ORADATA\TESTDB\USERS01.DBF'
CHARACTER SET EE8MSWIN1250
ALTER DATABASE OPEN RESETLOGS;
ALTER TABLESPACE TEMP ADD TEMPFILE 'C:\ORACLE\PRODUCT\10.2.0\ORADATA\TESTDB\TEMP01.DBF' REUSE;Is that correct?
About the RMAN backups: Wouldn't a 'CATALOG RECOVERY AREA' populate the controlfile with backup information again (I'm not using a recovery catalog in this case)?
Thanks for the help!
