or… boy that’s a long title!
If you’re running Oracle RAC databases on VMWare then you know how nice it is generally to manage. You can add memory and CPUs online, you can add disks to the operating system online. You can move the whole virtual machine from one ESX server to another online! Abstracting the hardware in this way makes a lot of things possible that cannot be done in the physical world. It’s a great time to be a system admin or a DBA. However, there is one little thing that you currently can’t do online through the VMware interface, and that’s add a shared disk to ASM. Can this be overcome? You betcha!
What’s the Problem?
Help on the Horizon
- First you are prompted to enter a pattern to match via an input dialog. Our client has hundreds of virtual machines. Instead of making them slog through a list of machines to click on the right one(s) we ask for a pattern to match against to shorten the result set. The code more or less comes from here.
- A multi-select list then allows the user to select the machines that are in the RAC cluster. Disks will be added to all of these machines.
- Then you are prompted for the number of disks, and their size in GB.
