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

[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

通过查询mos,发现相关文档:19C: While Executing Root.sh on Remote Nodes HIT UNEXPECTED “ERROR 4 OPENING DOM ASM/SELF IN 0x57f7d60″ (Doc ID 2571719.1)

确认是oracle一个bug,在20c版本中修复(20c没有对外发布,应该在21c中修复),这个bug不影响,可以忽略

最近实施了一套19c rac并且打上patch 32545008(GI Update 202104)和32399816(OJVM Update 202104),通过createGoldImage 创建了安装程序,直接使用该zip包即可安装含gi/db(含ojvm) 2021年4月的patch
