Clonando database usando RMAN

Database de Origem:

oracle@denilson:~> rman target /
Recovery Manager: Release 10.2.0.4.0 - Production on Thu Oct 1 15:07:49 2009
Copyright (c) 1982, 2005, Oracle. All rights reserved.
connected to target database: ORCL (DBID=3270432501)
RMAN> backup database plus archivelog;

* Copiar todos os backup pieces
* Copiar controlfile backup piece
* Copiar arquivo de parametros (init.ora)

Database Destino:

oracle@denilson_bkp:~> rman target /

Restaurar controlfile do backup piece:


RMAN> restore controlfile from '/u01/rman/backup/c-3932056136-20070213-02';
Starting restore at 13-SEP-09
using target database control file instead of recovery catalog
allocated channel: ORA_DISK_1
channel ORA_DISK_1: sid=155 devtype=DISK
channel ORA_DISK_1: restoring control file
channel ORA_DISK_1: restore complete,
elapsed time: 00:00:02
output filename=/u01/oracle/product/oradata/ora10g/orcl/control01.ctl
Finished restore at 13-SEP-09

RMAN> alter database mount ;

-- Catalogar todos os backup pieces copiados do banco de origem:

Exemplo:
RMAN> catalog backuppiece '/u01/rman/backup/o1_mf_annnn_TAG20070213T002925_2x21m6ty_.bkp';
Starting implicit crosscheck backup at 13-FEB-07allocated channel: ORA_DISK_1channel ORA_DISK_1: sid=155 devtype=DISK
Crosschecked 3 objects
Finished implicit crosscheck backup at 13-FEB-07
Starting implicit crosscheck copy at 13-FEB-07using channel ORA_DISK_1
Finished implicit crosscheck copy at 13-FEB-07searching for all files in the recovery areacataloging files..

-- Verificar após catalogar:

RMAN > list backup of archivelog all;

Caso a estrutura de diretórios no servidor de destino estiver diferente você pode renomear os arquivos:

-- Renomeando redo logs:
SQL> alter database rename file '/u01/oracle/product/oradata/ora10g/orcl/redo01.log' to '/u01/oracle/product/oradata/orcl/redo01.log';

-- Renomeando datafiles:
RMAN> run { set until sequence set newname for datafile 1 to '/u01/oracle/product/oradata/orcl/system01.dbf';
set newname for datafile 2 to '/u01/oracle/product/oradata/orcl/undotbs01.dbf'; set newname for datafile 3 to '/u01/oracle/product/oradata/orcl/sysaux01.dbf'; }


RMAN> restore database;

-- Caso foi necessário renomear os arquivos utilize o switch datafile:
RMAN> switch datafile all;

RMAN> recover database;

RMAN> alter database open resetlogs;

Index SKIP SCAN???

Index Skip Scan nada mais é que o "split" logico de um indice composto, ou seja, se sua clausula WHERE não tiver todos os campos do indice composto, ele é dividido em menores sub-indices Exemplo: -------- SQL> create table teste(a number,b number); Table created. SQL> begin 2 for i in 1..1000 3 loop 4 insert into teste values(i, 56); 5 end loop; 6 end; 7 / PL/SQL procedure successfully completed. SQL> create index idx_teste on teste(a,b); Index created. SQL> analyze table teste compute statistics; Table analyzed. SQL> explain plan for select /*+ index_ss(teste idx_teste) */ * from teste where b=56; Explained. SQL> start ?\rdbms\admin\utlxpls.sql -------------------------------------------------------------------------------- | Operation | Name | Rows | Bytes| Cost | Pstart| Pstop | -------------------------------------------------------------------------------- | SELECT STATEMENT | | 1...
