4 IB Interface configurálás I. Új IB VIP címek felvétele a hosts file-ba node1-ibvip.police.hu node1-bvip node2-ibvip.police.hu node2-ibvip node3-ibvip.police.hu node3-ibvip node4-ibvip.police.hu node4-ibvip 4 Copyright 2012, Oracle and/or its affiliates.

5 IB Interface configurálás II. VIP címek OCR-hez hozzáadása srvctl add vip -n node1 -A node1-ibvip/ /bondib0 -k 2 srvctl add vip -n node2 -A node2-ibvip/ /bondib0 -k 2 srvctl add vip -n node3 -A node3-ibvip/ /bondib0 -k 2 srvctl add vip -n node4 -A node4-ibvip/ /bondib0 -k 2 5 Copyright 2012, Oracle and/or its affiliates.

10 A centralizáció előnyei és hátrányai centralized database - egy helyen minden adat, nagy teljesítménnyel (+) Egy centralizált oldal nem elég, mert "single point of failure" - egyetlen konfig/db/szekrény felelős mindenért (-) -> Disaster oldal szükséges a cluster tagjainak hatása egymásra failover (+) rolling error (-) 10 Copyright 2012, Oracle and/or its affiliates.

15 Cluster felépítése és beállítása RAC cluster felépítés Lényeges különbség a hagyományos RAC-hoz: cluster_interconnect paraméternek az IB interconnect-re kell mutatnia ASM beállítás: SGA legalább 1GB, memory_target kikonfigurálása! (huge pages miatt) Cold Failover configuráció: van lehetőség single instance-ok cold failover módon való beállítására IB hálózat használata: Exadatán belüli adatbázisok közötti gyors adatáttöltés pl.
