Oracle 19c RAC 替换私网操作
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

3. 替换集群私网操作

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

sqlpus 一个简单的登录+退出使用了22秒,严重的慢,通过strace分析发现访问以下两个ip，但是10.11.0.41非常慢,10.13.0.41很快，并且通过一些信息53端口,判断可能是dns服务器的ip
connect(9, {sa_family=AF_INET, sin_port=htons(53), sin_addr=inet_addr("10.13.0.41")}, 16) = 0
connect(12, {sa_family=AF_INET, sin_port=htons(53), sin_addr=inet_addr("10.11.0.41")}, 16) = 0
进一步确认,确认是该服务器配置的dns服务器
[root@xifenfei ~]# cat /etc/resolv.conf # Generated by NetworkManager nameserver 10.13.0.41 nameserver 10.11.0.41
对这两个ip的连通性进行测试
[root@xifenfei ~]# ping 10.13.0.41 PING 10.13.0.41 (10.13.0.41) 56(84) bytes of data. 64 bytes from 10.13.0.41: icmp_seq=1 ttl=126 time=0.616 ms ^C --- 10.13.0.41 ping statistics --- 1 packets transmitted, 1 received, 0% packet loss, time 0ms rtt min/avg/max/mdev = 0.616/0.616/0.616/0.000 ms [root@xifenfei ~]# ping 10.11.0.41 PING 10.11.0.41 (10.11.0.41) 56(84) bytes of data. ^C --- 10.11.0.41 ping statistics --- 3 packets transmitted, 0 received, 100% packet loss, time 2063ms [root@xifenfei ~]#
确认10.11.0.41 ip不通,对于此类问题最快的解决方案就是除掉不可使用的dns服务器,然后测试登录和退出时间

通过除掉不可用的dns服务器ip之后,测试时间为1s,恢复正常
