  6. Hi Advait,

    I have read your CACHE FUSION article, I was very happy after reading that. I am a beginner in RAC and wish learn and write RAC certification. I need your help. Can you please drop your mobile number to contact you regarding this. Awating for your reply. I have only your hope to take forward on this. Please help me out.

  7. Hi Advait,
    Hit your site when I was actually searching for an article on “Concepts of Hot backup” for a colleague.
    Though I had read Ramavelpuri’s book on B&R long time back, your explanation was cool and straight.
    Will definitely recommend your site to others. I have spent almost 10 yrs of my career in Prod DBA but did not have a chance to do RMAN, RAC, DATAGUARD, ASM as client environment did not require it. I think your site will be helpful for me to kickstart them.

    Hats off to your good work.
    After all, knowledge is at its best when it is shared. And you are doing exactly the same.

  11. Hi,

    Nice technical presentation from you.

    Just wanted to check with you, is there a way to check the file system consumption current details (used, free) on the datafile resides on the server from dbms using any SELECT query.

    Want to avoid df -k and want to get details from the oracle. This way we can know details w/o connecting to the server from remote connection.

  15. Hi Advait,

    I am avid reader of your blogs and it do helps me in my knowledge and work..
    I seek your advice for an issue I am facing as given below:-

    We have an oracle instance on which 17 application runs and it has 17 different schemas for each application.
    Now by examining an AWR report for an identified timeframe, it is found one of those application schema is taking up much of the resources(CPU,Memory). My question to you–> can this affect the performance of other schemas as well for the reason one application schema is occupying more resources??

    Many Thanks,
