Re: Development environment for Oracle RAC

I didn't see a reply to this yet, so I'll give it a shot.

Most of the development environments I've seen at customer sites have had hardware configurations similar to the production environment, but usually fewer nodes, fewer CPUs and less RAM. For example, a production 3-node cluster with each system having 4 cores and 16 Gb RAM was paired with a development cluster having 2 nodes, 2 cores each and 8 Gb RAM each. While they still lack any environment to do load/stress testing on, at least they have an environment that should behave similarly with respect to functionality. Dev usually used storage similar to the production environment. If not the same array, another one just like it or maybe a little smaller, but used the same interface (iscsi, FC, or NAS).

I've seen lots of test/demo clusters built using VMs, but even the development clusters in all the corporate environments I've seen have been real hardware on real storage.

The most expensive part of every cluster in every case will likely be the Oracle licensing. Development environments are not free--they must be licensed too. Most sites tend to use named users on development since the dev team is relatively small. You'll have to work out the formula to figure out which option is best (cheapest) for your environment.

Hi there,

I was wondering what folks here use as their base hardware for an development environment that includes a Oracle RAC database backend.

Here's my setting: development is supposed to start in March and will be done in house. Production and reference environment will be colocated somewhere else (close to the client's clients). Setup of the   

Oracle environment should be finished by end of February and number one priority is the price at this point in time. Cheap is good ;)

A two-node RAC would do it for starters so this  http://www.oracle.com/technology/pub/articles/hunter_rac10gr2_iscsi.html   seems to cut it.

What about an inexpensive NAS filer as the shared storage solution?

Thanks in advance!
