No Lab anterior, vimos como configurar os Discos utilizando ASMLIB. Agora, o próximo passo é instalação do Grid.
Configurando Pré-requisitos
- Download Software (Grid Infrastructure)
# mkdir -p /u01/stage # chown oracle:oinstall /u01/stage
OTN: Oracle Database 12c Release 2 (12.2.0.1) Software (64-bit).
edelivery: Oracle Database 12c Release 2 (12.2.0.1) Software (64-bit)
- Configurar /etc/hosts
# vim /etc/hosts 127.0.0.1 srvoracle-asm localhost localhost.localdomain localhost4 localhost4.localdomain4
- Configurar Diretórios
# mkdir -p /u01/app/oracle/12.2.0/grid # chown oracle:oinstall /u01 -R
- Unzip Oracle Grid Software
$ cd /u01/app/oracle/12.2.0/grid $ unzip /u01/stage/linuxx64_12201_grid_home.zip
- Configurar SHM no Oracle Linux 7
# vim /etc/fstab tmpfs /dev/shm tmpfs defaults,size=2G 0 0
- Criar .profileGRID
$ vim /home/oracle/.profileGRID
Executar Instalador GRID
$ cd /u01/app/oracle/12.2.0/grid $ sh gridSetup.sh
- Alterar as opções:
Configure Oracle Grid Infrastructure for a Standalone Server (Oracle Restart) Grupo ADM do Oracle Asm: oinstall Grupo DBA do Oracle Asm: oinstall Change Discovery Path /dev/oracleasm/disks/
Verificando os Discos e Serviços
$ crsctl status res -t $ sqlplus / as sysasm COL NAME FORMAT A10; COL PATH FORMAT A30; SELECT MOUNT_STATUS,HEADER_STATUS,MODE_STATUS,STATE,TOTAL_MB,FREE_MB,NAME,PATH,LABEL FROM V$ASM_DISK; COL COMPATIBILITY FORMAT A10; SELECT NAME,STATE,TYPE,TOTAL_MB,FREE_MB,COMPATIBILITY,OFFLINE_DISKS FROM V$ASM_DISKGROUP;
