grid的安装

oinstall   grid, oracle     Oracle Inventory and Software Owner
dba        oralcle           Database Administrator
asmadmin   grid            Oracle Automatic Storage Management Group
asmdba     grid, oracle    ASM Database Administrator Group
asmoper    grid            ASM Operator Group
oper       oracle        Database Operator

 我碰到的问题是如果oracle不是asmdba的用户的话，dbca里面是看不见asm实例里面建立的diskgroup

而/dev/raw下面的权限，给grid:asmdba，让grid和oracle都可以读取。
 [root@orasrv rules.d]# cat /etc/udev/rules.d/60-raw.rules
# Enter raw device bindings here.
#
# An example would be:
#   ACTION=="add", KERNEL=="sda", RUN+="/bin/raw /dev/raw/raw1 %N"
# to bind /dev/raw/raw1 to /dev/sda, or
#   ACTION=="add", ENV{MAJOR}=="8", ENV{MINOR}=="1", RUN+="/bin/raw /dev/raw/raw2 %M %m"
# to bind /dev/raw/raw2 to the device with major 8, minor 1.
ACTION=="add", KERNEL=="sdb1", RUN+="/bin/raw /dev/raw/raw1 %N" 
ACTION=="add", KERNEL=="sdb2", RUN+="/bin/raw /dev/raw/raw2 %N" 
ACTION=="add", KERNEL=="sdc1", RUN+="/bin/raw /dev/raw/raw3 %N"
ACTION=="add", KERNEL=="sdc2", RUN+="/bin/raw /dev/raw/raw4 %N"
KERNEL=="raw*", OWNER="grid" GROUP="asmdba", MODE="0660"
  

# start_udev
# raw -qa
# ls -l /dev/raw

如果需要grid用户的crs能启动database，还需要将grid用户加入到dba组才可以启动，否则

[grid@orasrv ~]$ srvctl start database -d orclem
