手工删除19c rac

发表于 2024 年 12 月 15 日 由 惜分飞

在某些时候,需要删除掉手工删除19c RAC,重新安装,以下是比较简便的操作(root用户操作)

source /home/grid/.bash_profile
crsctl stop crs
systemctl disable oracle-ohasd
systemctl stop oracle-ohasd
systemctl disable oracle-tfa.service
systemctl stop oracle-tfa

rm -rf /etc/oracle
rm -rf /etc/ora*
rm -rf /u01
rm -rf /tmp/CVU*
rm -rf /tmp/.oracle
rm -rf /var/tmp/.oracle
rm -f /etc/init.d/init.ohasd
rm -f /etc/systemd/system/oracle-ohasd.service
rm -f /etc/systemd/system/oracle-tfa.service

dd if=/dev/zero of=/dev/asm_ocr1 bs=1024 count=1

Oracle 19c RAC 替换私网操作

发表于 2024 年 9 月 6 日 由 惜分飞

19c的三节点集群,需要替换一个私网网卡(如果有足够的停机窗口有一个更加简单的方法,直接通过修改网卡名称实现替换,不过需要主机重启一次,参考:Linux 8 修改网卡名称)
1. 先在主机层面确认新配置网络能够相互ping通,在hosts文件加入私网信息,并且确认ssh 可以相互访问

ssh xffdb1-priv3 date;ssh xffdb2-priv3 date;ssh xffdb3-priv3 date;

2. 删除掉需要删除的网络上的asm监听和该network信息

[grid@xffdb1 ~]$ srvctl config listener -asmlistener

3. 替换集群私网操作

ens9f0  172.16.16.0  global  cluster_interconnect,asm
ens6f0np0  172.18.18.0  global  cluster_interconnect,asm

4. 依次重启集群三个节点(ASMNET2LSNR_ASM监听需要人工kill),集群网络替换完成(因为asm listener已经有一个,另外一个私网不准备给他们加上asm listener),如果要增加可以进行如下操作

# srvctl add asmnetwork -netnum 2 -subnet 172.18.18.0
% srvctl add listener -asmlistener -l ASMNET1LSNR_ASM -subnet 172.18.18.0
