1 오라클 CRS(Cluster Ready Service)[편집]

1.1 개요[편집]

  • 10g R1에서 처음 소개됨 CRS 라 불림
  • 10g R2에서 Oracle Clusterware로 이름이 바뀜.
  • 11g R2부터 ASM + Clusterware를 묶어서 Grid Infrastrucoure 로 분류, OHAS(Oracle High Availablity Services) 라 칭함
  • 여전히 CRS라고 불림

1.2 CRS 시작/종료/상태 확인[편집]

Oracle Clusterware의 시작 , 종료 및 상태를 확인

1.2.1 CRS 시작[편집]

  1. HACMP 기동여부 확인

HACMP 기동 확인 : clstrmgrES,clinfoES 확인 

root# > lssrc -g cluster
  1. Shared Disks Mode 확인

Shared Disk가 모든 Node 에서 Access 가능한 상태 인지 확인 

root# > lsvg -o
  1. /usr/es/sbin/cluster/clstat 결과 확인
모든 Cluster Node의 상태가 모두 UP 상태이어야 한다. 
 이 때, 서버의 상태뿐만 아니라 Network Interface 등도 함께 확인한다.
  1. Oracle Clusterware Process 확인
  • CRS 시작 전 해당 Node의 CRS가 이미 기동되어 있는지 여부 확인 . 기동중인 상태에서 다시 Start해도 문제 발생하지 않음.
  • 다른 Node에서 start가 진행중인 경우 결과를 확인하고 서버별로 순차적으로 진행할것. 서버에서 동시에 실행할 경우 Race Condition이 발생할수 있음.
root# > ps -ef |grep d.bin
root# > crsctl check has
root# > crsctl check crs
root# > crsctl status resource -t -init
