介绍
One of the biggest obstacles preventing people from setting up test RAC environments is the
requirement for shared storage. In a production environment, shared storage is often provided by a
SAN or high-end NAS device, but both of these options are very expensive when all you want to do
is get some experience installing and using RAC. A cheaper alternative is to use a FireWire disk
enclosure to allow two machines to access the same disk(s), but that still costs money and requires
two servers. A third option is to use virtualization to fake the shared storage.
Using VirtualBox you can run multiple Virtual Machines (VMs) on a single server, allowing you to run
both RAC nodes on a single machine. In addition, it allows you to set up shared virtual disks,
overcoming the obstacle of expensive shared storage.
在开始安装之前,需要考虑以下几点。
完成的系统包括主机操作系统,两个客户操作系统,两组 Oracle Grid Infrastructure
(Clusterware + ASM)和两个数据库实例,所有这些都在一台服务器上。可以想象,这需
要大量的磁盘空间,CPU 和内存。
从最后一点开始,虚拟机每个都需要至少 4G 的 RAM,如果你不希望虚拟机疯狂交换,最好
还需要更多。不要以为你可以在小型 PC 或笔记本电脑上运行它。你不会。
