Oracle Clusterware Oracle Clusterware 기본동작 kill -9 LGWR Process Restart Automatically kill -9 listener PID Restart Automatically kill oracle.exe by Windows Task Manager Restart Automatically kill tnslsnr.exe by Windows Task Manager Restart Automatically When a Node dies VIP fails over to a different node g Release 2 is Protect 3 rd party Applications Oracle Clusterware 를사용하여 Single Instance 환경의 HA 기능도제공하며, Single Node / Local FileSystem 을 ASM 또는 Cluster FileSystem 인 OCFS 등으로전환하여 High Availability 기능을이용할수있다. 10g R1 까지지원되지않던 Non-Oracle Application 의 Failure Protect 기능이 10g R2 부터가능해졌으 므로본문서는위의기능을기반으로 Test 하였다 The H/A Framework 오라클에서제공하는고가용성솔루션은일반적으로 RAC 를의미한다. 이는최소두개 System 을기반으로 1 개의 Databaes 를노드개수만큼의인스턴스에서서비스를할수있는장점을가지고있다. 즉특정시스템에서장애가발생해도남아있는시스템에서서비스를계속수행하기때문에무중단서비스를구현이가능하다. H/A 기반은 Active Standby 구조로고가용성솔루션을제공한다. 9i 에서는 OS Vender Cluster 를기반으로만구현이가능하였는데 10g Clusterware 에서그기능을완벽하게수행할수있다. 아래문서는서로다른두개의 Database 구성하여각각 Active Standby Database 를구성을하고실제 failover 발생시어떻게지속적으로서비스수행이가능한지를구현하였다. H/A 는 RAC 에비해서 system fault 가발생하면 service down 이조금발생함을알려드립니다 Shared Resources - A common disks : OCR & Vote for Oracle clusterware system files - A common Network interconnect - Same OS - 3 -

1.2.2. 4 Node configurations - Node 1 : Running Oracle Instance & Clusterware, Protecting Application A - Node 2 : Running Oracle Clusterware, Protecting Application B - Node 3 : Running Oracle

4 Node configurations - Node 1 : Running Oracle Instance & Clusterware, Protecting Application A - Node 2 : Running Oracle Clusterware, Protecting Application B - Node 3 : Running Oracle Clusterware - Node 4 : Running Oracle Clusterware, Protecting Application C & D Oracle H/A 기본구성절차 Hardware 구성및 OS 구성은 10g RAC 설치와동일하게이뤄지며 Vendor Clusterware 없이구현이가능합니다. 1) install Oracle S/W Only into a new Oracle Clusterware HOME on the 2 nd Node 2) Install Cluster Filesystem both nodes 3) Modify Oracle Configurations - orapwd - init<sid>.ora - listener.ora, tnsnames.ora 4) Create / Tegister / Start / Relocate Resources - $ORA_CRS_HOME/crs/public - 4 -

5 Using the Application Framework 1) Create an VIP - required if the application is access via network clients 2) Create an Action Program - Oracle Clusterware to start, stop & query the status check - C, java or 기타 scripting language - => RAC sample code => 3) Create an Application Profile - Describes the process and limits to protect 4) Register the Application - Register the Application Profile with Oracle Clusterware 5) Set the permission on your Application - 5 -
