1) The document provides steps to create an Oracle database instance and configure Data Guard protection. It describes using DBCA to create the primary instance, enabling archiving and setting initialization parameters. 2) It then describes configuring the listener and tnsnames files on both the primary and standby servers. 3) Steps are provided to enable archiving on the primary, create a backup, and copy files to the standby to restore the database and register it as a managed recovery standby.

1. Pontos para criar Instancia e depois Data Guard
usar o aplicativo "dbca" para criar instancia
-> create database
-> custom database
-> SID = <nome da instancia> [normalmente -> AGORANG]
Global Database Name = SID
-> TAB ENTERPRISE MANAGER <desligar tudo>
-> Use common location for all database files <path para os datafiles>
[normalmente -> /oradata]
-> Flash recovery <path para os datafiles + SID> [normalmente ->
/oradata/AGORANG/flash_recovery]
-> enable archives <alterar a extensão para *.arc">
<definir path para os archives> [normalmente ->
/oraarch/AGORANG]
-> database componentes <desligar tudo>
-> TAB memory: custom: SGA = 1512 e PGA = 1024
-> TAB sizing: processes = 600
-> TAB character settings: character set = WE8ISO8859P15-ISO 8859-15 West
European [WE8ISO8859P15]
Default Language = BRAZILIAN PORTUGUESE
-> opção ALL INITIALIZATION PARAMETERS:
open_cursos = 800
os_authent_prefix = <limpar conteudo>
-> Redo Log Groups: abrir cada item e mudar o file size para '102400' K Bytes
