RMAN Database Restore ASM

RMAN Database Restore ASM

Description:
In this blog, we are going to see take RMAN backup in asm storage and restore the database to another server.

RMAN Restore ASM:
Take the backup using RMAN in source host copy the backup into destination host, using that backup files to restore the database.

Overall Steps:

Source server:
1. Backup Database using RMAN
2. Create pfile from spfile
3. Copy the backup files to the destination server

Destination server:
1. Edit pfile
2. Create Required Folders in destination server
3. Add the database entry in oratab
4. Startup using pfile Nomount stage
5. Restore control file
6. Mount database
7. Catalog backup pieces
8. Restore and recover the database
9. Change dbname/DBID uisng NID
10. verify the database name and id.

Source Server:

Step 1: Take backup using RMAN:

Create backup directory:

Backup script:
run {
allocate channel t1 type disk;
allocate channel t1 type disk;
allocate channel t1 type disk;
backup incremental level 0 database format ‘/u01/share/backup/database_%d_%u_%s’;
release channel t1;
}
sql ‘alter system archive log current’;
run {
allocate channel a1 type disk;
backup archivelog all format ‘/u01/share/backup/arch_%d_%u_%s’;
release channel a1;
}
run {
allocate channel c1 type disk;
backup current controlfile format ‘/u01/share/backup/Control_%d_%u_%s’;
release channel c1;
}
exit

Connect RMAN and execute the script:

[oracle@asm ~]$ rman target /

Check the backup file location:

Step 2: Create pfile from spfile

create pfile=’/home/oracle/initasmora.ora’ from spfile;
Step 3: Copy the backup file into destination server

[oracle@asm backup]$ scp * [email protected]:/u01/backup/

Destination server:

Step 1: Edit pfile
Change DB_UNIQUE_NAME in the pfile:

*.audit_file_dest=’/u01/app/oracle/admin/oraasm/adump’
*.audit_trail=’db’
*.compatible=’19.0.0′
*.control_files=’+DATA/ASMORA/CONTROLFILE/current.262.1092813933′,’+DATA/ASMORA/CONTROLFILE/current.261.1092813933′

*.db_name=’oraasm’
*.db_recovery_file_dest=’+DATA’
*.db_recovery_file_dest_size=12732m
*.db_unique_name=’asmora’                —–>change db unique name
*.diagnostic_dest=’/u01/app/oracle’
*.dispatchers='(PROTOCOL=TCP) (SERVICE=oraasmXDB)’
*.enable_pluggable_database=true
*.local_listener=’LISTENER_ORAASM’
*.open_cursors=300

*.processes=300
*.remote_login_passwordfile=’EXCLUSIVE’
*.sga_target=1886m
*.undo_tablespace=’UNDOTBS1′
[oracle@asm dbs]$

Step 2: Create Required Folders

Create required folders in the destination server
[oracle@asmnew ~]$ mkdir -p /u01/app/oracle/admin/ASMORA/adump/

Step 3: Add the Database entry in oratab file.

ASMORA:/u01/app/oracle/product/19.0.0/dbhome_1:N

Step 4: startup database using pfile nomount stage

[oracle@asmnew asmora]$ export ORACLE_SID=asmora
