CREATION OF 9i STANDBY DATABASE through RMAN.
PRE-REQUISITES: RMAN catalog in use and use of external media management layer
configure on both machines.
PRIMARY SITE: ITLINUXDEVBLADE07
STANDBY SITE:ITLINUXDEVBLADE08
DATABASE: dgtest9i.
Login to catalog and set configuration from primary database:
Export ORACLE_SID=dgtest9i
rman target / catalog rman/rman@rmanp

2. Create orapwd file in $ORACLE_HOME/dbs
> orapwd file=orapwdgtest9i entries=10 password=oracle
3. Make changes to tnsnames.ora and listener.ora to include log_shipping entries
on both machines and both listeners should be running
4. Export ORACLE_SID=dgtest9i ( on standby site)
SQL> startup nomount ;
PRIMARY SITE- ITLINUXDEVBLADE07:
Four scripts will be used….Please create these .rcv files in /opt/oracle/rman/scripts
area.
cd /opt/oracle/rman/scripts.
Create the four scripts…
1. backup_database.rcv
run {
allocate channel ch1 type \'SBT_TAPE\'
parms
\'ENV=(TDPO_OPTFILE=/opt/tivoli/tsm/client/oracle/bin64/tdpo.dgtest9id.opt)\'
format \'d_%d_%u_%p_%c\';
backup current controlfile
for standby;
release channel ch1 ;
}
2. standby_control_file.rcv
run {
allocate channel ch1 type \'SBT_TAPE\'
parms
\'ENV=(TDPO_OPTFILE=/opt/tivoli/tsm/client/oracle/bin64/tdpo.dgtest9id.opt)\'
format \'d_%d_%u_%p_%c\';
backup current controlfile
for standby;
release channel ch1 ;
}
3. arch_backup_range.rcv
run {
allocate channel ch1 type \'SBT_TAPE\'
parms
\'ENV=(TDPO_OPTFILE=/opt/tivoli/tsm/client/oracle/bin64/tdpo.dgtest9id.opt)\'
format \'d_%d_%u_%p_%c\';
backup archivelog
from logseq
1 until logseq
32 thread 1 ;
release channel ch1 ;
}
4. makeme_standby.rcv
run {
allocate channel ch1 type \'sbt_tape\'
parms
\'ENV=(TDPO_OPTFILE=/opt/tivoli/tsm/client/oracle/bin64/tdpo.dgtest9id.opt)\';
allocate auxiliary channel aux1 type \'sbt_tape\'
parms
\'ENV=(TDPO_OPTFILE=/opt/tivoli/tsm/client/oracle/bin64/tdpo.dgtest9id.opt)\';
set limit channel ch1 kbytes=3145728
readrate
200;
set until sequence = 32 thread =1;
duplicate target database for standby
dorecover
;
release channel ch1 ;
release channel aux1 ;
}
Now start the process on the PRIMARY site.
1. BACKUP DATABASE PLUS ARCHIVELOGS....
rman target / catalog rman/rman@rmanp cmdfile=backup_database.rcv
After backup is complete.
2. CREATE STANDBY CONTROLFILE.
rman target / catalog rman/rman@rmanp cmdfile=standby_control_file.rcv
After standby controlfile is created.
3. SWITCH A FEW LOGS.

The size of the standby redologs must be the same as the primary online redologs.
Create one more standby redolog that number of online redologs.
Next on standby ...recover managed standby database disconnect;...to start
managed recovery.
The database protection_mode will be maximum performance.
Select protection_mode from v$database;
To change to maximum availability, a restart of the primary database is
required.
To change the protection_mode to maximum availability:
Shutdown primary.

Alter database set standby database to maximize availability;
alter database open;
Warning: The alter database open command will fail if there are no standby logs
created on standby site when database protection_mode is maximum availability.
