[2025-05-29] Interconnect Private IP 정보 변경(네트워크 인터페이스명 변경) (12cR2)

 

[테스트 개요]

목적: 12cR2 2노드 RAC( DRDB1/DRDB2 )에서 인터커넥트 인터페이스를 enp0s8 → enp0s9로 변경(10.0.0.0/24).

절차: 각 노드 CRS 정지/비활성화 → udev로 NIC rename(enp0s9) + ifcfg 변경/재부팅 → oifcfg setif로 enp0s9 등록 → CRS 기동/자동시작 활성화.

검증/정리: oifcfg getif로 enp0s9=cluster_interconnect,asm 확인 후, enp0s8 항목 oifcfg delif로 제거.

 

 

1. 테스트 환경 정보

OS : Oracle Linux Server 7.9 (Linux rdb01d 5.4.17-2102.201.3.el7uek.x86_64)
DB : Oracle Database 12c Enterprise Edition Release 12.2.0.1.0 - 64bit Production
RAC1 : rdb01d(192.168.0.31) : DRDB1
RAC2 : rdb01d(192.168.0.32) : DRDB2

 

2. 네트워크 인터페이스 정보 조회

 

[+ASM1:grid@rdb01d][/home/grid]$ oifcfg getif
enp0s3  192.168.0.0  global  public
enp0s8  10.0.0.0  global  cluster_interconnect,asm

 

3. Interconnect Network 인터페이스를 enp0s8에서 enp0s9로 변경

 

--> enps0s9를 추가함

[+ASM1:grid@rdb01d][/home/grid]$ oifcfg setif -global enp0s9/10.0.0.0:cluster_interconnect,asm

[+ASM1:grid@rdb01d][/home/grid]$ oifcfg getif
enp0s3  192.168.0.0  global  public
enp0s8  10.0.0.0  global  cluster_interconnect,asm
enp0s9  10.0.0.0  global  cluster_interconnect,asm
