Summary of installation of Virtualbox+oracle 11g R2 RAC

Yesterday, the installation and commissioning of Oracle 11G R2 RAC on the VirtualBox virtual machine was done with reference to documents on Oracle base, and the installation documentation was detailed, but it was the first time that the RAC was installed on the OEL. Now write down some of the major issues and solutions for future reference.

The first is the memory problem, the minimum requirement is each virtual machine 1.5GB of memory, because the machine memory is limited, just start to 1GB want to cheat the past, the results installed grid control and so on for several hours are uncertain, had to cancel redistribution 1.5GB to RAC1,1.2GB to RAC2, Finally reluctantly installed to complete, however, the operation response is very slow, waste a lot of time, so it is strongly recommended that conditions allow each virtual machine to allocate at least 3GB of memory, especially the node that performs the installation needs more allocation point of memory, usually first installed on the RAC1 and then copied to another node (RAC2), The database is installed on node one (RAC1) and then cloned to node two (RAC2), so feel the implementation of the installation of the node (RAC1) requires more memory, of course, the more the better.

Second, when the grid is installed, two scripts are required to be executed on each node as root, and in order to improve speed we may be able to execute both scripts on each node at the same time, which can cause errors. The right thing to do is to execute the script in the node first and then the node two, and if you're unlucky, you'll need to wait for the first node to finish running the root.sh script, then delete the node registration resource on the second node and then execute the script again.
