RMAN Backup dan Recovery Oracle 10g
Sebagai acuan untuk prosedur backup dan recovery dengan RMAN
1. RMAN dapat melakukan back up pada semua file database yang dibutuhkan untuk recovery pada saat terjadi kerusakan. RMAN support back up file-file
a. Datafile, dan image copy dari datafiles
b. Control file, dan image copy dari control file
c. Archived redo logs
d. file parameter server
e. Backup pieces, yang berisi backup lain yang dibuat oleh RMAN
2. Menggunakan RMAN O/S authentication
[oracle@iscdd bin]$ cd $ORACLE_HOME/bin
[oracle@iscdd bin]$ ./rman target / NOCATALOG
RMAN> exit
Recovery Manager complete.
3. Menggunakan RMAN Password authentication
[oracle@iscdd bin]$ cd $ORACLE_HOME/bin
[oracle@iscdd ~]$ ./rman target system/ora NOCATALOG
RMAN> exit
Recovery Manager complete.
4. Konfigurasi RMAN agar dapat diakses oleh user tertentu.
SQL> create tablespace rman_ts
datafile ‘/u02/oradata/iscdd/rman_ts01.dbf’
size 5M
segment space management auto;
SQL> alter tablespace rman_ts
Add datafile ‘/u02/oradata/iscdd/rman_ts02.dbf’
size 5M;
SQL> create user rman_user identified by rman123
default tablespace rman_ts
quota unlimited on rman_ts;
SQL> grant connect, resource, recovery_catalog_owner to rman_user;
SQL> exit
5. Konfigurasi RMAN, setting catalog dengan user tertentu.
[oracle@iscdd ~]$ cd $ORACLE_HOME/bin
[oracle@iscdd bin]$ ./rman CATALOG rman_user/rman123@iscdd TARGET sys/ora@iscdd

18. Copy spfile
SPFILE, Server Parameter File, adalah sebuah file binary yang digunakan oracle sebagai parameter initialization. Parameter dapat diubah menggunakan ALTER SYSTEM SET, dimana parameter hanya berubah pada SPFILE.
PFILE adalah traditional text based dari parameter file init.ora. Umumnya disimpan pada directory $ORACLE_BASE/admin/SID/pfile, dan symbolic link berada di directory $ORACLE_HOME/dbs.
