RMAN: Error al abrir la base de datos ORA-00600 arguments: [2898], [6]

El otro día tratando de recuperar una Base de Datos con RMAN en 11.2.0.3 y RHEL 5 hasta un punto en el tiempo, todo iba funcionando como debería de ser, los datafiles se recuperaron, se aplico los archived redo logs y en el momento de tratar de abrir la base de datos con open resetlogs, me salio, como diria "Chabelo", una espantosisima y tremenda "X", o sea un error ORA-00600.

Y de ahí ya no pude abrir la base de datos, hasta que hice los pasos que hago abajo :(

ORA-00600: internal error code, arguments: [2898], [6], [12], [], [], [], [], [], [], [], [], []
Process ID: 17480

 Aquí  no voy a entrar a detalle de como sucedió el error, si no mas bien como lo puedes solucionar si se te llega a presentar.

Lo que si te voy a decir es que tiene que ver que tiene que ver con las encarnaciones que se encuentran presentes en el controfile y este error lo he podido replicar cuando después de tener varias encarnaciones, hago un reset database to incarnation N;

Como te decía no me voy a concentrar a decirte como replicarlo, si no como tener una manera de solucionarlo, ya que no te vas a encontrar con mucha información con respecto a este error, ni siquiera en MOS.

Lo primero que hay que hacer es restaurar la base de datos hasta el punto en el tiempo que necesitas, en el ejemplo que te presento también recupere el archivo de parámetros así como el controlfile del respaldo.

No se te olvide antes de iniciar con RMAN tener la variable de ambiente de UNIX NLS_DATE_FORMAT puesta,

export NLS_DATE_FORMAT='DD-MON-YYYY HH24:MI:SS'

De igual manera, te va a servir esta variable

export ORA_RMAN_SGA_TARGET=1000

Para ponerlo por puntos separados esto fue lo que hice en la primera parte, en un archivo llamado restore_TESTDB_A.rmn:

  1. Restaurara el archivo de parametros del respaldo.
  2. Reiniciar la Base de datos después de restaurar el archive de parametros para que tomara el spfile que acabo de restablecer.
  3. Cambiar el parámetro cluster_database a FALSE (Solamente RAC)
  4. Restaurar el controlfile del respaldo
  5. Reiniciar la base de datos para que el parámetro de cluster_database se tome en cuenta, ya que no es un parametro dinamico.
  6. Cambiar a la Quinta encarnación de la Base de Datos, ya que ahi es donde es a donde quiero llegar
  7. Restaurar la Base de Datos al punto en el tiempo que quiero llegar

Aquí te presento el log de la primera etapa, así como el script que se corrió, lo corte un poco para que no tomara tanto espacio, pero si lo quise poner para que supieras que paso

 Ya cuando haya finalizado la restauración de los datafiles, lo que tenemos que hacer es recrear el control file tomando un respaldo hacia un archivo plano. Aquí es una parte muy delicada que yo te recomendaría hacer un listado de tus respaldos en RMAN (list backup) y  guardar un log, ya que al recrear el controlfile, vas a perder esta información si es que estas usando tu controlfile para respaldos.

 Yo lo que hago en lugar de borrar el controlfile actual lo renombro ,si no estas usando ASM, seria con el comando mv, si estas usando ASM seria de la siguiente manera con el usuario grid y entrando a la instancia de ASM

ALTER DISKGROUP GBS_HRMS_DATA RENAME ALIAS '+GBS_HRMS_DATA/DBATEST/CONTROLFILE/control02.ctl'
     TO '+GBS_HRMS_DATA/DBATEST/CONTROLFILE/control02.ctl.old';

 Una vez que moviste los controlfiles , modifica el archivo plano del conrolfile que creamos arriba, y corre el script en sqlplus
