REHL8 oracle 19C RAC安装中的坑

检查共享的NFS权限
[root@nymtx ~]# id grid
uid=6001(grid) gid=5001(oinstall) groups=5001(oinstall),5003(asmdba),5004(asmoper),5005(asmadmin)
[root@nymtx ~]# id oracle
uid=6002(oracle) gid=5001(oinstall) groups=5001(oinstall),5002(dba),5003(asmdba),5005(asmadmin)

gird 和Oracle同属 asmadmin 组,所以asmadmin要有写限,用以下命令加权限
chmod g+s /asm/*
问题如下:
allocated channel: ORA_DISK_1
channel ORA_DISK_1: SID=266 device type=DISK
channel ORA_DISK_1: starting datafile backup set restore
channel ORA_DISK_1: specifying datafile(s) to restore from backup set

2.DNS 问题是一个BUG可以直接忽略

3.以下IP不需要指定网卡,写在/etc/hosts 中就可以
192.168.1.83 nymtxvip.inno.com nymtxvip
192.168.1.84 hzmtxvip.inno.com hzmtxvip
192.168.1.85 mtscan.inno.com mtscan

4.出现问题要查找日志
