11g RAC DBCA建库报错ORA-15001 ORA-15025
环境：rhel 7.4 Oracle 11.2.0.4 rac
故障1：
在DBCA建库的时候，报错ORA-15001，告警日志中为ORA-15025:could not open disk "/dev/asm_data’。
/bin/sh: /etc/oracle/setasmgid: Permission denied
查看/etc/oracle/setasmgid文件大小为0
解决方法：
$ su - grid
$ cd <Grid Home>/bin
$ ./setasmgidwrap o=/u01/app/oracle/product/11.2.0/db_1/bin/oracle
如果执行命令报错，提示权限问题
root下手动给/etc/oracle/setasmgid777权限
