DG不能自动mount导致数据库不能正常启动:ORA-01157、ORA-01110、ORA-17503、ORA-15001、ORA-15001
现象:
每次重启整个CRS之后,DB都不能自动开启到OPEN状态,查看alert日志报错:

从alert日志可以看出,INDX DG的文件不能被读到,
查看发现INDX DG处于DISMOUNT状态。

分析:
ASM中创建了2个DG:UNID,INDX.每次只有UNID会被自动mount,而INDX不能被自动MOUNT。
查看asm_diskgroups参数发现只设置了UNID,,这就是为什么每次INDX不会被自动MOUNT的原因了。
SQL>
SQL> show parameter asm

NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
asm_diskgroups string UNID
SQL> show parameter pfile

NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
spfile string

解决办法:
将INDX添加到asm_diskgroups参数中。
spfile:alter system set asm_diskgroups='UNID','INDX' scope=both;
pfile:修改pfile中asm_diskgroups参数。
