11G:SYSASM role

Starting from Oracle 11g ASM, new privilege has been created for Administering Oracle ASM instances. This is called SYSASM role.

You can continue using SYSDBA role to connect to ASM but it will generate following warning messages at time of startup/shutdown, create Diskgroup/add disk, etc.

<strong>adrci&gt; show homes</strong>

ADR Home = /u03/app/oracle/diag/asm/+asm/+ASM:
Starting ORACLE instance (normal)
<strong>WARNING: Deprecated privilege SYSDBA for command 'STARTUP'</strong>

Please note that SYSASM privilege cannot be used to start the RDBMS instance. This way it ensures separation of database administration privilege from the ASM storage administration privilege. Trying to do so results in ORA – 1031

As per documentation, the privilege to administer an ASM instance with SYSDBA will be removed in future versions. Anyways till now DBA’s can administer the ASM instance 😉
