          1. HI Anju,

            I have reading your RAC11 G2 blogs from last 1 year. These are really helpful . I have one doubt here :

            Can we use OCFS for storing OCR and voting Disk. If yes do we still required OLR.

          2. Hi Neeraj,

            Thanks for your time and feedback. We can use OCFS for storing OCR and voting Disk. OLR will still be required. Same algorithm is used whether OCR/VD are stored on ASM or not.

  12. HI Anju ,

    I have some doubt in OEM 12c about configuration

    1 ) I have 18 OEM servers in different countries ie in different TimeZones . Now I want to use all targets which are in different country from one location ie from one OEM sevrer .
    For that I have opened Network Plociy for commnucating across country . NOw my question is how to setup agent in 1 OEM of different Time Zones.

    2) In OEM 12c Create and use multitarget os/sql JObs : So in this case I have around 2400 servers and for the compalince purpose I have to change every 30day my OS password ( oradb – for oracle
    grid – for Grid Infrastructure ) . So can it be change from there ( OEM ) ? Because from normal OS user ( other than root) /etc/passwd & /etc/shadow file can’t update and when I put passwd command in OEM 12c to change password in multiple hosts it will ask me to put the password . I mean how I can change password from OEM 12c of OS user ?

  13. Hi Anju,

    I would like to thank you for all the time and effort you have taken in creating such a wonderful and simple to follow blog on Oracle. I am an aspiring DBA but for one doubt which are very silly that is…. I wish to know….
    1. What is the scope of a DBA after say like 10 years with respect to job profile and availability in market for such senior post
    2. Apart for being a corporate traineer and freelancer what else can one get into after 15 years of hardwork ???

    1. Hi Kasturi,

      Thanks for the time you spent in reading my blog.
      A DBA has to keep himself abreast of the latest developments in his field. Everyday a new problem poses a new challenge for him and solving those problems makes him more experienced in his field. It is the experience and craving for learning that makes a DBA indispensible in his organization. My motto is ” Chase Quality and Quantity will chase you”.

      If you are the best in your field, nobody can stop you. The opportunities will come to you – You need not look for them. Instead of thinking about what opportunities will be available, simply go on doing your job dedicatedly and results will follow automatically.

      You can become a consultant, corporate trainer, ACE director, author , reviewer, Blogger — depends on your aptitude. There is no dearth of opportunities for hard working person.

      Hope it does not sound like a sermon.

  14. Hi Anju,

    First of all many thanks for sharing your knowledge, really appreciate that, Please keep up the good work.

    Secondly, Could you please suggest some good books or articles to understand the Oracle Internals ?? I am really interested in understanding the internals but the documents/articles are scattered so couldn’t give a systematic approach for studying these internals.

    When I say internals, I mean for every action that Oracle does, details of which process does that, what memory it utilizes and from where and who allocates how it allocates, inter process communication. I understand that’s a lot but I have a lifetime to study, at least sharing the approach would be much much appreciated.

    Regards
    Junior DBA

  15. Hi Anju,

    Can you Tell me how anyone can Start the learning ORACLE DBA.
    I am a SQL DBA and want to learn ORACLE DBA activities. Please suggest.

    Regards,
    Anshul Joshi

    1. Hi Anshul,

      To learn Oracle DBA, first you will need to learn Basic Database Administration which involves learning SQL, Oracle Database Administration workshop-I and Oracle Database Administration workshop-II. Since you are already SQL DBA, you may learn SQl on your own by referring to online oracle documentation. For Workshop-I and II, you may join a training institute or seek training from a freelancer. If you want to get certified, you will have to join some training institute since you need hands on training certificate for the same.

      Hope it helps
