Introduction

One of the biggest obstacles pre$enting people fro* setting up test RAC en$iron*ents isthe re,uire*ent for shared storage. &n a production en$iron*ent/ shared storage is oftenpro$ided b a #A or high0end A# de$ice/ but both of these options are $er expensi$e"hen all ou "ant to do is get so*e experience installing and using RAC. A cheaperalternati$e is to use a ire2ire dis% enclosure to allo" t"o *achines to access the sa*edis%(s)/ but that still costs *one and re,uires t"o ser$ers. A third option is to use!"are #er$er to fa%e the shared storage.

3sing !"are #er$er ou can run *ultiple irtual !achines (!s) on a single ser$er/allo"ing ou to run both RAC nodes on a single *achine. &n additon/ it allo"s ou to setup shared $irtual dis%s/ o$erco*ing the obstacle of expensi$e shared storage.

-efore ou launch into this installation/ here are a fe" things to consider. The finished sste* includes the host operating sste*/ t"o guest operating

sste*s/ t"o sets of Oracle Cluster"are/ t"o A#! instances and t"o 'atabaseinstances all on a single ser$er. As ou can i*agine/ this re,uires a significanta*ount of dis% space/ C+3 and *e*or. & "as able to co*plete this installationon a 4. +entiu* "ith 4 of *e*or/ but it "as extre*el slo".

This procedure pro$ides a bare bones installation to get the RAC "or%ing. There

is no redundanc in the Cluster"are installation or the A#! installation. To addthis/ si*pl create double the a*ount of shared dis%s and select the 6or*al6redundanc option "hen it is offered. Of course/ this "ill ta%e *ore dis% space.

'uring the $irtual dis% creation/ & al"as choose not to preallocate the dis% space.

This *a%es $irtual dis% access slo"er during the installation/ but sa$es on "asteddis% space.
