Migrando Banco de Dados Oracle Single para ASM non-RAC

https://thegreathighway.com/hbz8zx6cn Este artigo tem como objetivo mostrar como migrar o Banco de Dados Oracle “Single” para “ASM” porém não para RAC.
Vamos utilizar a versão 10.2.0.5 do Banco de Dados Oracle para realizar a migração.

https://aaerj.org.br/2024/05/13/p238cje0lwe Para iniciarmos devemos estender os discos colocados que será os discos do ASM (Automatic Storage Management).

https://templedavid.org/symons/fuvj6yhvp
Vamos listar os discos disponíveis no servidor de Banco de Dados.
OBS: Todos os procedimentos a seguir são realizado com o usuário “root”.

https://discovershareinspire.com/2024/05/j4of7hwh16u Vamos utilizar os discos para o ASM o “sdb”,”sdc”,”sdd”,”sde”,”sdf”,”sdg”,”sdh” e “sdi”.
Vamos formatar os discos e criar as partições no mesmo.

Buy Alprazolam 0.5 Mg Agora precisamos privilegiar o usuário “oracle” para os dispositivos, para que na próxima reinicialização do Sistema Operacional o usuário “oracle” seja possível subir a instância “ASM”.

source site Exite duas maneiras:

https://dentaris-sa.com/2024/05/13/84v7iug 1 – Podemos conforme abaixo no arquivo “rc.local” garantir privilégios nos dispositivos butos (RAW) para o usuário “oracle” do grupo “dba”;
2 – Criar o arquivo “99-raw-perms.rules” dentro do diretório “/etc/udev/rules.d/” e garantir privilégios nos dispositivos butos (RAW) para o usuário “oracle” do grupo “dba”;.

https://www.vertaglia.com/njdg22r658 Vou mostrar das duas formas.

https://photovisions.ca/rsdczl4fi9 No arquivo “rc.local”.

https://grannysglasses.com/?p=xus88k7yq chown -R oracle.dba /dev/raw/raw[1-8] chmod 660 /dev/raw/raw[1-8]

https://discovershareinspire.com/2024/05/3iq1bn481ld Vamos acrescentar no arquivo as linhas acima.

[root@serveroracle scripts]# cd /etc/ [root@serveroracle etc]# cat rc.local #!/bin/sh # # This script will be executed *after* all the other init scripts. # You can put your own initialization stuff in here if you don't # want to do the full Sys V style init stuff. touch /var/lock/subsys/local [root@serveroracle etc]# vi rc.local [root@serveroracle etc]# cat rc.local #!/bin/sh # # This script will be executed *after* all the other init scripts. # You can put your own initialization stuff in here if you don't # want to do the full Sys V style init stuff. touch /var/lock/subsys/local chown -R oracle.dba /dev/raw/raw[1-8] chmod 660 /dev/raw/raw[1-8] [root@serveroracle etc]#

No arquivo “99-raw-perms.rules”.

KERNEL=="raw[1-8]", MODE="0660", GROUP="dba", OWNER="oracle"

Vamos acrescentar no arquivo as linhas acima.

[root@serveroracle rules.d]# vi 99-raw-perms.rules
[root@serveroracle rules.d]# cat 99-raw-perms.rules
KERNEL=="raw[1-8]", MODE="0660", GROUP="dba", OWNER="oracle"

Pronto, preparamos os dispositivos e vamos criar a instância ASM.
Com o usuário “oracle” vamos verificar o ambiente de banco de dados.

[root@serveroracle ~]# su - oracle

Conforme informações acima, o nosso Banco de Dados Oracle “dbprod” está executando. Vamos conferir algumas informações no mesmo para realizarmos a migração do ambiente SINGLE para ASM.
Verificando o Listener.

Vamos criar a instância ASM. (Veja as Imagens na Galeria para a Criação da Instância ASM).
Com o DBCA vamos criar a instância ASM e após a criação vamos visualizar se as instâncias estão executando.

[oracle@serveroracle ~]$ dbca

Num outro terminal vamos executar com o usuário “root” durante a criação da instância “+ASM” o comando abaixo para criar o OCR.

[root@serveroracle ~]# /oraprd01/app/oracle/product/10.2.0/db_1/bin/localconfig add

Vamos verificar o status do Enterprise Manager.

Porque como houve restauração e recuperação completa do Banco de Dados através do um backup do “controlfile’, isso gera uma nova incarnação do Banco de Dados.

Vamos remover o SPFILE do filesystem e no arquivo “initdbprod.ora” vamos adicionar o novo caminho do SPFILE do “+DGDADOS”.

[oracle@serveroracle ~]$ cd /oraprd01/app/oracle/product/10.2.0/db_1/dbs/
[oracle@serveroracle dbs]$ cp -p spfiledbprod.ora spfiledbprod.ora.bkp
[oracle@serveroracle dbs]$ rm spfiledbprod.ora

Vamos verificar no ASM o caminho do SPFILE para colocar no arquivo “initdbprod.ora”.

[oracle@serveroracle dbs]$ export ORACLE_SID=+ASM

Vamos iniciar o Banco de Dados com o SPFILE e verificar o mesmo.
