RMAN BACKUP SHELL SCRIPT

Ekim 29, 2020Ocak 3, 2021 tarihinde gönderilmiş Faruk Çevik tarafından

Bu örneğimizde veritabanımız için 3 günde bir gece 03:00 da full backup alsın hergün incremental Level -1 backup, bu arada bloack change tracking file oluşturup bu dosyayıda enable yapalım, 6 saatte birde archive loğların yedeğini alsın, şeklinde bir kurguyu script olarak hazırlamaya çalışalım.

Burada işlemci sayımıza göre uygun bir channel sayısı ayarlanmalıdır. Ben 8 channel ile 8 parallelik derecesinde backup alıyorum siz kendi sisteminize ve ihtiyacınıza göre artırıp azaltabilirsiniz.

Level 0 full backup için scriptimizi oluşturalım, daha sonra oluşturduğumuz scriptleri crontab a ekleyeceğiz.

vi /u01/scripts/rman_L0.sh
export TIME=$(date +"%Y%m%d")
export ORACLE_BASE=/u01/app/oracle
export ORACLE_HOME=/u01/app/oracle/product/19.0.0.0/db
export ORACLE_SID=frkdb
export LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib
export PATH=$PATH:$HOME/bin:$ORACLE_HOME/bin
rman target / < /u01/scripts/rman_L0.scr > /u01/scripts/log/rman_full'date +\%Y\%m\%d\_%H\%M'.log

rman_L0.scr dosyamızı hazırlayalım

vi /u01/scripts/rman_L0.scr

Archive log backupları için;

vi /u01/scripts/rman_archive.sh

export TIME=$(date +"%Y%m%d")
export ORACLE_BASE=/u01/app/oracle
export ORACLE_HOME=/u01/app/oracle/product/19.0.0.0/db

rman target / < /u01/scripts/rman_archive.scr > /u01/scripts/log/rman_archive'date +\%Y\%m\%d\_%H\%M'.log

rman_archive.scr dosyasını hazırlayalım

vi /u01/scripts/rman_archive.scr

sql 'alter system archive log current';
sql "alter session set nls_date_format=''dd.mm.yyyy hh24:mi:ss''";

L1 Backup ları için ;

export TIME=$(date +"%Y%m%d")

rman target / < /u01/scripts/rman_L1.scr > /u01/scripts/log/rman_full'date +\%Y\%m\%d\_%H\%M'.log

rman_L1.scr dosyasıı hazırlayalım;

vi /u01/scripts/rman_L1.sh

export TIME=$(date +"%Y%m%d")
export ORACLE_BASE=/u01/app/oracle
export ORACLE_HOME=/u01/app/oracle/product/19.0.0.0/db

rman target / < /u01/scripts/rman_L1.scr > /u01/scripts/log/rman_incr'date +\%Y\%m\%d\_%H\%M'.log

rman_L1.scr dosyasını hazırlayalım ;

vi /u01/scripts/rman_L1.src

sql ‘alter system archive log current’;

}

Şimdi bu oluşturdğumuz scriptleri Linux crotab a ekleyerek backuplarımızın otomatik olarak çalışmasını sağlayalım
