Database Software

Folks,

Hello.
I am installing Oracle Database 11gR2 RAC system using 2 Virtual Machines (rac1 and rac2) on the top of VMPlayer 3.

The VM rac1 and rac2 run correctly when one of them is shutdown.
Their locations are F:\VM_RAC\rac1 and F:\VM_RAC\rac2.


While rac2 is running, I open rac1. But this error message comes up:

Error: "Cannot open the disk F:\VM_RAC\sharerac\asm1.vmdk or one of snapshot disks it depends on. Reason: failed to lock the file."


While rac1 is running, I open rac2. But this error message comes up:

Error: "Cannot open the disk F:\VM_RAC\sharerac\asm1.vmdk or one of snapshot disks it depends on. Reason: failed to lock the file."


The 2 error messages are the same. This means I cannot open 2 VMs rac1 and rac2 at the same time. When we run RAC system, we have to open 2 machines or more than 2 machines at the same time so that all machines can access the same Database Server.

My question is:

Can any folk tell me how to have rac1 and rac2 run at the same time ?

Thanks.
