    How worthy learning RAC??!!!

    user8983130
      Hi,

      I have 3 years experience in oracle database administration. In our organization , we use single instance database management system. There is no chance in near future we would implementing RAC. Now a days, i saw almost in every recruitment there is need for RAC. So , i have decided to learn RAC on my own cost. But i find the expense is huge...cost of learning RAC=3 months of my salary , this puts me into thinking should i go for this?? What you ppl think..will RAC stay for a long time or another feature will down it within 1-2 years??

      Regards,

            We do not use anything but RAC these days. And RAC do seems to be far more widely use elsewhere too.

            I think it definitely worth your while to get to know RAC. Learning IMO is best done in a practical fashion. You can build a virtual 2 node RAC on a modern desktop. This will give you a basic grounding in the basics of how to setup a RAC server nodes (e.g. ssh equivalence, shared storage), install Grid Infrastructure and RAC, and build ASM and RAC instances.

              You may build your own RAC system with 100gb hdd and min 6gb RAM easliy. If any new technology comes, your RAC experience will definitely help you out. You may use below link for building inexpensive RAC system for practice purpose.
