https://www.techonicsltd.com/uncategorized/oxs74zrl5 Neste artigo estarei relatando como pode ser feito uma duplicação de um database em Oracle RAC 10g com ASM para um Database Single em Filesystem.
https://autismwish.org/co9n9i6k https://gsaudemarketing.com.br/wnnvql71 Objetivo:
https://ict-pulse.com/2024/07/xqso0qj Fazer uma base de teste com os dados do meu banco de produção RACRAFA. O nome da base de teste deverá se chamar DBTESTE.

Ordering Tramadol Online Cod Devemos primeiramente copiar os arquivos para o mesmo local que foi feito o backup, pois o duplicate irá se basear pelo catalogo do banco de produção.

Feito a copia dos arquivos do backup vamos começar o processo de duplicação.

Identificado o Completion Time dos ultimos archives as 06/12/2011 as 19:05 vamos fazer o duplicate até nesse horario, porem com um minuto antes.
Passo 2
Configurar o tnsnames do servidor srv-dbteste para que eu possa acessar a base de producao
tnsnames.ora
RACRAFA1 =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.10.106)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = RACRAFA)
(INSTANCE_NAME = RACRAFA1)
)
)
Passo 3
Agora vamos criar um pfile e o orapwd para iniciar o dbteste
ORAPWD
$ orapwd file=orapwdbteste password=oracle10g
PFILE
$ cat $ORACLE_HOME/dbs/initdbteste.ora
db_block_size=8192
db_file_multiblock_read_count=16
open_cursors=300
db_domain=""
db_name=dbteste
background_dump_dest=/ora01/app/oracle/admin/dbteste/bdump
core_dump_dest=/ora01/app/oracle/admin/dbteste/cdump
user_dump_dest=/ora01/app/oracle/admin/dbteste/udump
control_files=("/ora02/oradata/dbteste/control01.ctl", "/ora02/oradata/dbteste/control02.ctl", "/ora01/oradata/dbteste/control03.ctl")
job_queue_processes=10
compatible=10.2.0.3.0
processes=150
sga_target=167772160
audit_file_dest=/ora01/app/oracle/admin/dbteste/adump
remote_login_passwordfile=EXCLUSIVE
pga_aggregate_target=16777216
undo_management=AUTO
undo_tablespace=UNDOTBS1
log_archive_dest_1='LOCATION=/ora02/arch/dbteste/'
log_archive_format=dbteste_%t_%s_%r.arc
db_file_name_convert='+DGDADOS/racrafa/datafile/','/ora02/oradata/dbteste/','+DGARCH/racrafa/tempfile/','/ora02/oradata/dbteste/','+DGDADOS/racrafa/tempfile/','/ora02/oradata/dbteste/'
log_file_name_convert='+DGARCH/racrafa/onlinelog/','/ora02/oradata/dbteste/'
_no_recovery_through_resetlogs=TRUE
Deve ser observado os parametros db_file_name_convert e log_file_name_convert, devem ser adicionados no pfile da instancia dbteste para converter os diskgroups para filesystem no momento do duplicate.
O parametro _no_recovery_through_resetlogs deve ser colocado no init para que possa ser aberto a primeira vez o banco pois o banco de origem tem dois redos e ele tentará fazer recover a partir do seguindo redo, assim que o banco for aberto em modo resetlogs pode ser removido o parametro do init e reinicializa-lo.
Outro detalhe importante é criar os diretorios que serão utilizados para a base dbteste.
No meu caso:
mkdir -p /ora02/arch/dbteste/ mkdir -p /ora02/oradata/dbteste/ mkdir -p /ora01/oradata/dbteste/ mkdir -p /ora01/app/oracle/admin/dbteste/bdump mkdir -p /ora01/app/oracle/admin/dbteste/cdump mkdir -p /ora01/app/oracle/admin/dbteste/udump mkdir -p /ora01/app/oracle/admin/dbteste/adump
Passo 4
Agora iremos para o processo de duplicação e primeiramente vamos iniciar a instancia dbteste em modo nomount

Passo 5
Ainda conectados ao servidor srv-dbteste executar o rman com o alvo(target) no banco de produção e ao ser duplicado no auxiliary, conforme mostrado abaixo:
rman target sys/oracle10g@racrafa1 auxiliary /
run {
ALLOCATE AUXILIARY CHANNEL aux1 DEVICE TYPE DISK;
set until time "to_date('06-12-2011 19:04','dd-mm-yyyy hh24:mi')";
DUPLICATE TARGET DATABASE TO dbteste;
}
Agora mostrando o processo executando ….

Finished Duplicate Db at 08-DEC-11
BINGO ! O banco já foi duplicado de racrafa para dbteste.
Agora pode ser removido o parametro _no_recovery_through_resetlogs do init e reiniciar a instancia.
Obs.: Cuidado com o processo de duplicate e seu tempo de retenção de backups. Faça o duplicate que termine o processo dentro do intervalo da retenção do backup.
Ex.: Retenção de 1 dia
Backup full é agendado todos os dias as 18:00
Backup feito dia 06/12/2011 as 18:00 e terminou as 19:05
E o seu duplicate é iniciado dia 07/12/2011 deve terminar antes do proximo agendamento dia 07/12/2011 as 18:00 ou melhor aumente o tempo de retenção, ou atrase o seu backup para executar somente após o seu duplicate.
