rac中 ora.bc2.srv offline 怎么办

关于RAC节点服务orarac2gsd的offline问题解决方法
我没有时间去测试，先记录下来。当看到bolg时，会想起这回事。去测试一下
模拟节点故障时,rac2的vip顠到了rac1,CRS重构后,rac2重新启动发现如下情况:
[oracle@rac2 bin]$ /crs_stat -t -v
Name Type R/RA F/FT Target State Host
----------------------------------------------------------------------
oraC1inst application 0/5 0/0 ONLINE ONLINE rac1
oraC2inst application 0/5 0/0 ONLINE ONLINE rac2
oraRACdb application 0/1 0/1 ONLINE ONLINE rac2
oraSM1asm application 0/5 0/0 ONLINE ONLINE rac1
oraC1lsnr application 0/5 0/0 ONLINE ONLINE rac1
orarac1gsd application 0/5 0/0 ONLINE ONLINE rac1
orarac1ons application 0/3 0/0 ONLINE ONLINE rac1
orarac1vip application 0/0 0/0 ONLINE ONLINE rac1
oraSM2asm application 0/5 0/0 ONLINE ONLINE rac2
oraC2lsnr application 0/5 0/0 ONLINE ONLINE rac2
orarac2gsd application 0/5 0/0 ONLINE OFFLINE
orarac2ons application 0/3 0/0 ONLINE ONLINE rac2
orarac2vip application 0/0 0/0 ONLINE ONLINE rac2
检查节点一:
[oracle@rac2 bin]$ /srvctl status nodeapps -n rac1
VIP is running on node: rac1
GSD is running on node: rac1
Listener is running on node: rac1
ONS daemon is running on node: rac1
检查节点二:
[oracle@rac2 bin]$ /srvctl status nodeapps -n rac2
VIP is running on node: rac2
GSD is not running on node: rac2
Listener is running on node: rac2
ONS daemon is running on node: rac2
手工重启服务:
[oracle@rac2 bin]$ /srvctl start nodeapps -n rac2
再次检查如下:
[oracle@rac2 bin]$ /srvctl status nodeapps -n rac2
VIP is running on node: rac2
GSD is running on node: rac2
Listener is running on node: rac2
ONS daemon is running on node: rac2
这时候,服务一切正常:
[oracle@rac2 bin]$ /crs_stat -t -v
Name Type R/RA F/FT Target State Host

区别就在于阿里云使用都是私有公网IP地址，而你自己的内网使用的内网地址，即使有私有公网IP也不是单独分配给服务器，而是分配给了防火墙，如果私有地址直接接入服务器就可以实现广域网端到端的访问。

是的，RAC环境的VIP地址和物理IP可以不同网段。在RAC环境中，两个节点可能是不同环境（物理或虚拟机），两个节点的IP可以使用私有的非公共网段。此外，VIP（虚拟IP）也可以使用公共网段，支持客户端通过其访问RAC集群。
