개요

Tibero 7.2.2 버전에서 CM (Cluster Manager) Resource의 자동 재시작(Auto restart) 설정 방법을 다룹니다.
(resource 전체가 아닌 일부 내용을 다룹니다.)
 

방법

CM 기동

# tbcm -b
CM Guard daemon started up.
import resources from '/cm/cmresource'...

TBCM 7.1.1 (Build 277758)TmaxTibero Corporation Copyright (c) 2020-. All rights reserved.Tibero cluster manager started up.
Local node name is (cm1:18629).

 

CM Service Auto Restart 활성화 - Service Auto start mode on

[root] # cmrctl act service --name [as service name]
Auto-boot mode is activated (tas)

[root] # cmrctl act service --name [db service name]
Auto-boot mode is activated (tac)


[root] # # cmrctl show

Service 확인

[root] # cmrctl show service --name [as service name]
Service Resource Info
=================================================
Service name    : tas
Service type    : Active Storage
Service mode    : Active Cluster
Cluster         : cls
Inst. Auto Start: ON
Interrupt Status: COMMITTED
Incarnation No. : 2 / 2 (CUR / COMMIT)
=================================================
| INSTANCE LIST                                 |
|-----------------------------------------------|
| NID   NAME    Status  Intr Stat ACK No. Sched |
| --- -------- -------- --------- ------- ----- |
|   1      cm1 UP(NRML) COMMITTED       2     Y |
|   2      cm2 UP(NRML) COMMITTED       2     Y |
=================================================

[root] # cmrctl show service --name [db service name]

=================================================
Service name    : tac
Service type    : Database
Service mode    : Active Cluster
Cluster         : cls
Inst. Auto Start: ON

테스트 방법

TAS / TAC Process kill 또는 TAS / TAC Instance down 등 Instance down 후 cmrctl show 로 STATUS BOOTING → UP 되는지 확인하는 방법은 아래와 같습니다. 

 [root] # kill -9 ps -ef|grep tbsvr_MGWP |grep -v grep|awk '{print $2}'
참고
CM에서 RESOURCE STOP시 아래와 같은 문구가 출력됩니다.
[root] # cmrctl stop db --name tac1
Cannot stop instance of service 'tac' manually (Auto-start mode is on)
