    Hi Kellyn,

    My company is planning to install on OEM 12c version on RAC 2 node and a standby cluster (RAC 2 node) using Dataguard. I need a small clarification regarding the installation of OMS and OMR is it a good practice to install the OMS and OMR on the same server or do I need a separate server for installation of OMS. The number of targets we are going to monitor is <1000. Please let me know if I am going to install the OMR and the OMS on the same cluster will there be any performance issues. Please help me

    Thank you


  • I would definitely have separate OMR and OMS machines. This post may help you out with the sizing, etc. of your EM environment project:

    Hi Kellyn,

    I ran into a problem with the Agent12c that seems to be under documented.
    I’ve got a Linux host with over 200 small databases. Consolidation is not an option.
    The agent seems to have a very hard time to handle that, in fact, it gracefully shuts itself down after a long period of being ‘running but not ready’. This problem occurs when I am, manually, discovering databases and adding them to OEM at a rate of about 20 at a time.
    Whilst not crashed yet, it displays lines like
    Target Manager Current Activity : Compute Dynamic Properties (total operations: 37, active: 9, finished: 28)
    Apparently this takes to much time. After the agent startup I can get as many as 5 lines of dots before a shutdown. If by some work of magic it does start, I can bet that within half an hour it will shut itself down.
    Am I asking too much of the agent?

    Any hints into the right direction will be much appreciated.

  • Hi Pom,
    Could you tell me what release you are on of EM12c? This will change my answer depending on the version we are on considering some of the new tools we have available in the console vs. in earlier versions.

  • Pom

    Will this answer the question?
