Task 1: Preparing to Use the Oracle Suggested Backup Strategy

To use the Oracle suggested backup strategy, ensure that:

The database is ARCHIVELOG mode
The fast recovery area size is configured, or a default device for storing backups is configured.
You have added a database host user to the OSBACKUPUPDBA operating system group, for operating system authentication.

Task 2: Create the Backup full Script-UNIX and Linux

[oracle@SERVER_DATABASE rman]$ pwd

/u01/app/oracle/rman_backup

[oracle@SERVER_DATABASE rman]$ more backup_script_full.sh

#!/bin/bash

ORACLE_HOME=/u01/app/oracle/product/12.1.0.2/db_1;export ORACLE_HOME

ORACLE_SID=orcl; export ORACLE_SID

PATH=$PATH:$ORACLE_HOME/bin; export PATH

chk_date=`date +%d`

chk_parity=`expr $chk_date % 2`

export bkdir=/backup11

BACKUP_DIR=$bkdir; export BACKUP_DIR

export DATA_DIR=$BACKUP_DIR/backup_full

export ARC_DIR=$BACKUP_DIR/backup_full

export BACKUP_DATA=$DATA_DIR/$ORACLE_SID"_data_f%t_s%s_s%p"

export BACKUP_ARC=$ARC_DIR/$ORACLE_SID"_arc_f%t_s%s_s%p"

export ORACLE_OWNER=oracle

export DATE=`date +%Y%m%d`

export IP=168_133
