E agora o que fazer???

O banco caiu e não sobe… e agora?Olá DBA ! Tudo bem?! ELA CHEGOUUUU!!!!!! Viva!!! Até que enfim é sexta-feira! E de feriadão ainda hein??? Aproveite! Curta, brinque pule, porém, sem perder a dignidade. rsrsrs.
Eu particularmente não curto a festa do Carnaval, porém o feriado sempre é bom para dar uma quebrada na rotina. Ficar com a família, amigos, enfim cumprir com a maior missão do ser humano: Ser feliz.
Mas, como ainda é sexta-feira, dia útil e vida de DBA é isso mesmo, eu sempre falo que passamos a semana inteira com todo o ambiente funcionando redondinho, chega na sexta-feira, pronto… Começam os “pepinos”, “abacaxis”, a feira inteira inventa de acontecer nos 48 minutos do segundo tempo. Vamos lá DBA! Hoje é sexta-feira, 13:20 da tarde você na contagem regressiva e alguém grita: “CAIU O BANCO DE DADOS do sistema…
Banco caiu é complicação pra nossa vida, pode ser problema à vista… E como disse o sábio Murphy… É claro que após verificar você percebe que realmente é problema.
O que fazer? Chorar? Tentar botar  a culpa em alguém? Sair correndo? Pedir demissão?
NÃO DBA! Por mais que sinto um desejo enorme de fazer qualquer uma destas coisas, use nossa técnica. Respire fundo e aproveite para aumentar o seu portfólio de problemas resolvidos e clientes felizes, Portanto FAÇA e depois não esqueça da teoria da galinha… hehehe avise a todos que VOCÊ fez.

Segue abaixo um roteiro completo de como proceder para restaurar um banco de dados onde foi perdido tudo.
Siga ele conforme indicado, caso tenha alguma dúvida jamais exite! Poste sua dúvida! Eu não garanto saber tudo, ninguém sabe! Mas prometo responder tudo!

====================================================
– Banco de Dados: Oracle 11g 11.2.0.1 – Enterprise Edition
– Sistema Operacional: Red Hat Advanced Server 4 Update 4
– Modo de arquivamento: Archivelog Ativo.
– Backup: Backup RMAN FULL (Online, Inconsistente, Hot).
– IMPORTANTE: Ter em mãos o DBID=1207426900
– Objetivo: voltar o Backup até o ultimo ponto de recuperação possível.
====================================================
1- PREPARAR UM NOVO SERVIDOR PARA RESTAURAR O BACKUP
====================================================
– Prepara um novo Servidor com Oracle instalado para restauração do Backup RMAN
– Instalar apenas o Software Oracle
====================================================
2- RESTAURAR O SPFILE
====================================================
RMAN TARGET /
RMAN>SET DBID=1207426900
RMAN>startup nomount
RMAN>restore spfile from ‘/oracle11g/backupRMAN/backup_FULL_RMAN_220609/controlfile.ctlc-1207426900-20090622-00’;
Starting restore at 22-JUN-09
using target database control file instead of recovery catalog
allocated channel: ORA_DISK_1
channel ORA_DISK_1: sid=36 devtype=DISK
channel ORA_DISK_1: autobackup found: /oracle11g/backupRMAN/backup_FULL_RMAN_220609/controlfile.ctlc-1207426900-20090622-00
channel ORA_DISK_1: SPFILE restore from autobackup complete
Finished restore at 22-JUN-09
RMAN> shutdown immediate
Oracle instance shut down
====================================================
3- RESTAURAR O CONTROLFILE
====================================================
RMAN>SET DBID=1207426900
RMAN> startup nomount
database is already started
RMAN> restore controlfile from ‘/oracle11g/backupRMAN/backup_FULL_RMAN_220609/controlfile.ctlc-1207426900-20090622-00’;
Starting restore at 22-JUN-09
allocated channel: ORA_DISK_1
channel ORA_DISK_1: sid=1091 devtype=DISK
channel ORA_DISK_1: restoring control file
channel ORA_DISK_1: restore complete, elapsed time: 00:00:01
output filename=/oracle11g/oradata/ORCL/control01.ctl
output filename=/oracle11g/oradata/ORCL/control02.ctl
output filename=/oracle11g/oradata/ORCL/control03.ctl
Finished restore at 22-JUN-09
RMAN> alter database mount;
database mounted
released channel: ORA_DISK_1
====================================================
4- SINCRONIZAR O BACKUP
====================================================
RMAN> CROSSCHECK BACKUP;
RMAN> CROSSCHECK COPY;
RMAN> CROSSCHECK backup of controlfile;
RMAN> CROSSCHECK archivelog all;
RMAN> DELETE EXPIRED BACKUP;
RMAN> delete obsolete device type disk;
RMAN> list backup;
====================================================
5- RESTAURAR O BANCO DE DADOS ORACLE
====================================================
RMAN> restore database;
