    Change count and type of CPUs in RHEL on HP Server


    In order to reduce our Oracle licensing costs on some Test/Dev servers, we are considering changing out CPUs on an HP Gen 7 server that running RHEL 5.9. The server was re-purposed and is now overpowered for what we need. The existing server has 2 CPUs, each with 6 cores. We want to remove BOTH CPUs and then put a single quad core CPU back in. One admin is saying we might have to "reinstall Linux". Can someone give me advice about what steps needs to be taken in Linux to make this happen? Do we need to rebuild the kernel or do some other sort of reconfiguration for Linux to recognize the new CPU configuration? Thanks in advance for any advice.

    Hi and welcome

    No, changing the cpu will not result in a reinstall.

    However, there might be impact on the oracle configuration, especially max parallel servers, threads etc.
    I am not an oracle expert, but probably some parameters need to be set manually.

    Another point is support and warranty for your HP machine.
    Depending on where the cpu is from and your contracts, this might or might not invalidate hp support.

    Great, thanks for the input. Oracle won't be installed until after we deal with the CPUs. Had we realized the licensing cost sooner, we would've waited on installing Linux. The HP warranty is a a bit of a grey area but as this is a repurposed server and is already a generation behind, and the server is non-production, we're going to run the risk as we simply can't afford to license Oracle under the current CPU configuration.

    Will we need to do any reconfiguration in Linux or will the kernel pickup the new config automatically when it boots?

    No need to configure cpus in linux in general.

    One more thing:
    RedHat 5.9 is supported and will be for a while. Therefore it is appropiate for production use.
    However, Redhat 6 is long released and oracle supports it.
    So as there is need for a system reconfigure anyway, it might be a good time to upgrade.
