Oracle 11g ASM R2 new features

Today I was reading the new features document on Oracle 11g R2. Oracle has introduce lot of cool features like asmcmd enhasments,diskgroup parameters.This week I am planning to test these parameters on my test box.Looks like DBA life with oracle 11g will be very easy and hope it will not have any bugs.

Disk Group parameters:

-au_size Not its possible to set the au size to 1M,2M,4M,8M...64M.

-access control Wow....access control at the ASM level

-compatible.rdbms

-compatible.asm


Force Disk Group Drop:

DROP DISKGROUP DATA01 FORCE INCLUDING CONTENTS;

With 10g we have to format the disks sometimes.

ASMCMD commands:

-Now we can stop, start the asm instance through ASMCMD.

-Disk group creation from ASMCMD
