【Oracle】ORACLE RAC 19c集群管理默认三个节点,删除无用节点3配置

ORACLE RAC 19C默认有三个节点,若安装两节点的RAC,则第三个节点就会显示disabled ,不利于监控,容易故障误报。

解决方案:srvctl modify asm -count ALL
如下:

[root@orcl1 ~]# srvctl config  asm -detail
ASM home: <CRS home>
Password file: +OCR/orapwASM
Backup of Password file: +OCR/orapwASM_backup
ASM listener: LISTENER
ASM is enabled.
ASM is individually enabled on nodes: 
ASM is individually disabled on nodes: 
ASM instance count: 3
Cluster ASM listener: ASMNET1LSNR_ASM
[root@orcl1 ~]#
[root@orcl1 ~]# srvctl modify asm -count ALL
[root@orcl1 ~]#
[root@orcl1 ~]# srvctl config  asm -detail
ASM home: <CRS home>
Password file: +OCR/orapwASM
Backup of Password file: +OCR/orapwASM_backup
ASM listener: LISTENER
ASM is enabled.
ASM is individually enabled on nodes: 
ASM is individually disabled on nodes: 
ASM instance count: ALL
Cluster ASM listener: ASMNET1LSNR_ASM
[root@orcl1 ~]#
