parted /dev/vda --script mklabel gpt
parted /dev/vda --script mkpart primary 0% 100%
parted /dev/vda --script set 1 lvm on

pvcreate /dev/vda1
vgcreate vg_u01 /dev/vda1
lvcreate -n lv_u01 -l 100%FREE vg_u01

parted /dev/vdc --script mklabel gpt
parted /dev/vdc --script mkpart primary 0% 100%

parted /dev/vdd --script mklabel gpt
parted /dev/vdd --script mkpart primary 0% 100%

Etiquetar discos

oracleasm createdisk DATA01 /dev/vdc1
oracleasm createdisk FRA01  /dev/vdd1
oracleasm listdisks

5. Instalación Grid Infrastructure (19.26)

Variables grid

export ORACLE_BASE=/u01/app/grid
export ORACLE_HOME=/u01/app/19.0.0/grid
export ORACLE_SID=+ASM
export CV_ASSUME_DISTID=OL9

Instalación silenciosa aplicando RU

./gridSetup.sh -silent \
-responseFile /home/grid/grid_silent.rsp \
-applyRU /home/grid/p38298204_190000/38298204 \
-waitforcompletion \
-ignorePrereqFailure

Validar:

crsctl stat res -t

---

6. Crear Diskgroup FRA

sqlplus "/ as sysasm"

CREATE DISKGROUP FRA
EXTERNAL REDUNDANCY
DISK 'ORCL:FRA01';

---

7. Instalación Oracle Database 19.26

Variables oracle

export ORACLE_BASE=/u01/app/oracle
export ORACLE_HOME=/u01/app/oracle/product/19.0.0/dbhome_1
export ORACLE_SID=CDB1
export CV_ASSUME_DISTID=OEL8

Instalación Software Only con RU

./runInstaller -silent -waitforcompletion \
-applyRU /home/oracle/p38291812_190000/38291812 \
oracle.install.option=INSTALL_DB_SWONLY \
oracle.install.db.InstallEdition=EE \
DECLINE_SECURITY_UPDATES=true

---

8. Creación de Base de Datos

dbca -silent -createDatabase \
-templateName General_Purpose.dbc \
-gdbname cdb1 \
-sid CDB1 \
-createAsContainerDatabase true \
-numberOfPDBs 1 \
-pdbName FJA1 \
-storageType ASM \
-datafileDestination "+DATA" \
-recoveryAreaDestination "+FRA" \
-characterset AL32UTF8

Notas

• La base queda en NOARCHIVELOG por defecto.
• Configurar ARCHIVELOG según requerimientos.
• Validar RU aplicado con opatch lsinventory.
