一、登錄ASM實例html

若是以sysdba身份登錄asm實例進行維護，在執行一些操做的時候會遇到以下錯誤:node

node1-> sqlplus / as sysdba

ERROR at line 1:
ORA-15032: not all alterations performed
ORA-15260: permission denied on ASM disk group

究其緣由在於sysdba身份權限不足，須要以sysasm身份進行登錄sql

SQL> conn / as sysasm
Connected.

此時再執行相關的維護操做便可oracle

SQL> alter diskgroup dg1 mount;

Diskgroup altered.

SQL> alter diskgroup fra1 mount;

Diskgroup altered.

SQL> alter diskgroup high_dg1 mount;

Diskgroup altered.

SQL> alter diskgroup normal_dg1 mount;

Diskgroup altered.

SQL> select name,state from v$asm_diskgroup;

NAME                           STATE
