How to Install Oracle 11g Release 2 on OEL 5.4 on VirtualBox: Managing ASM with ASMCA
In the previous post, I have tried to explain how to install Grid Infrastructure on your VirtualBox instance. In this post, before moving to the next post in which I will be explaining RDBMS 11g Release 2 configuration, I wish to look at a new tool shipped with Grid Infrastructure, namely ASMCA(ASM Configuration Assistant).
We will not be going deep with ASMCA in this post but rather it will be just like a first contact with aliens. ASMCA is a very capable and accompanying tool with the new capabilities of ASM like ADVM or ACFS.
Starting with ASMCA
ASMCA is the youngest member of Oracle *CA family. It seems that ASM users will be using it actively for management by the new features in 11g Release 2. Such as,
- ASM Volume (ADVM) Management
- ASM File System (ACFS) Management
- Read-only snapshot management

Hi,
REally nice content you have putup here. I have also one question regrading ASM. I want to install RAC on Solaris sparc box. When start the grid installation I made a selection for Advance option because want to configure RAC on 2 nodes. when select the ASM for the “storage option information screen” (steps 7 out of 15) and then click next.There were no disks I can see, where I have already shared few partition. Do you have any idea why is it so?
If you refer to my previous post on Grid Infrastructure installation at ASM diskgroup creation step you will see on the bottom of the screen that you can modify “Change Discovery Path”. Ensure that the regular expression in this string match with your ASM devices. The second point is that please ensure that the ownership of those devices belong to Grid Infrastructure user (oracle/grid) and mode of those devices are at least 660. The final point is that if you are using multipath devices there are some sharp edge issues with some multipath devices:
For example on solaris I remember that if you are not skip first 1M of the device and then label devices with EMC powerpath ASM discovery will fail event that the above issues are solved. For more please refer to Multipath tutorial of your vendor.
Wonderful article about ASM with proper screenshots. Thanks a lot for sharing.
