11g RMAN Substitution Variables

We can now use SQL*PLUS type substitution variables in RMAN like &1, &2 and so on and the same can be linked to shell scripts as shown below with the new clause USING where we are passing the Incremental Level and the backup tag to the actual RMAN command.

Also note that in 11g we can run RMAN scripts using the ‘@’ like a SQL script

testbkp.rcv

connect target sys/oracle
run{
backup incremental level &1
database
tag &2;
}
exit;

testbkp.sh

#! /bin/ksh
export level=$1
export tag=$2_`date +%d%b%y`
rman @testbkp.rcv using $level $tag

Note the actual RMAN command that is run …….. it adds a date along with the tag name (parameter 2) and runs a level 2 backup as the first parameter was ‘2’

apex:/u01/oracle> ./testbkp.sh 2 dly_inc_bkp
