Summary of experience
 An Oracle DBA with over 5 years experience with UNIX Systems and with Oracle Databases.

During my 5 years working in the IT industry I have been exposed to a wide range of technologies and developed a broad set of technical skills. I have developed a very strong background in Oracle Databases, UNIX and NT4 (including Windows 2000) Systems, as well as gaining experience in project management.

I have worked in Production environments as an Oracle DBA and in Development environments as Oracle DBA/Developer, and adapt well to both. My background, communication and documentation skills help in bridging the gap between business people, database administrators and UNIX system administrators.

    i am also very much instrested in working on oracle.
    i am currently preparing for ocp fundamentals exam.
    lokking forward for your reply.

    regards sunil

  2. Hi Sunil
    I’d suggest you to read documentations and some Oracle books. Refer to tahiti.oracle.com and there you can find 2 Days Administration Guides which will guide you through the basic administration tips
    Moreover, you should practice a lot. Without practicing, you will not be able to learn more
    I’d suggest you to refer to Oracle Ace Tonguc Yilmaz’s well written article, related with Oracle Introduction for newbies. You can find it from below link:
    http://tonguc.files.wordpress.com/2009/06/oracle-introduction-for-newbies.doc

    Good Luck. Keep reading, practicing and asking your questions (of course after google-ing it 😉 ) on OTN forums 🙂

    Hi Kamran Agayev,

    I need the links for Books on RMAN backups and on Datapump.

    And i need some critical scenarious which we face as DBA.

    Thanks & Regards,
    Krishna

  6. Hi Krishna. The link of the book is on my home page 🙂 But this book hasn’t finished yet, so when it’ll be finished, I’ll inform you
    In this book, you’ll see many different scenarious which every DBA may face in his career

  7. aniruddha said

    hello kamran. i want to learn oracle and start a career as dba. i am a rhce. but am confused which exam i will go for. will i go for 9i dba exams or 10g dba exams particularly. and there is also 11g. plz advice me which way to go? i also want to learcn rac. and another q, is it necessary to learn pl/sql if i work as dba.

    thx for this wonderful blog. i have completed installing 10g on centos 5.3 using virtualbox v3.

  8. Hi aniruddha and welcome to my blog
    If you’re at the beginning of Oracle career, don’t try to start from exam. Try to read some docs (Administrators Guide and Concept) from http://tahiti.oracle.com

    Then, I’d suggest you to read Sybex books to prepare to Oracle exams. Yes, there’re mainly 3 different versions in Oracle which you can give an exam. 9i is not supported version of Oracle but to be more successful, I’d suggest you to start learning from 9i. Because there’re many things that were automated in 10g. By starting from 10g or 11g, you may be aware of some Oracle features (especially in Performance Tuning). It’s my suggestion. But you can even start from 11g. It’s the new supported version
    But remember, to be 11g OCP by having any 9i or 10g exam, you’ll need to pass only one “New Features” exam. It’s the same for 10g. If you passed 9i exams, you’ll need to pass only one exam to be 10gOCP and another one exam to be 11gOCP

    It’s necessary to know SQL and PL/SQL to be successfull DBA. You don’t need to learn PL/SQL at developers level, but you need to know some basics as well

    Good Luck!

    thx a lot kamran for ur suggestion. i will surly start from oracle 9i.

    Salam Kamran muallim . Man ozum Java proqrammistam . Lakin hala hech vaxt Oracle-la islamamisam . Esasen MySQL -le ishlemisem . Database-ler haqqinda yaxshi melumatim var .PL/SQL-i ise bilmirem .
    1. Siz mana hansi kitablari maslahat gorerdiniz ki baslayim oxumaga ?
    2. Eger praktiki masalalarda tetbiq ede bilmeyecemse oxumagin na daracada faydasi olacaq (sadece bizim proyektde Oracle tetbiq edilmir 😦 )

  11. Salam Rufat

    Evvela sen ozune kankret bir yön secmelisen. DBA olmaq isteyirsen yoxsa Developer? Onlar ferqli ferqli seylerdi. Eslinde her DBA bir developer kimi development-i bilmelidi (bu Oracle-da beledi). Amma her Developer ise DBA kimi administration bilmese de olar

    Eger bundan sonra Java-ya davam edeceksense, onda Oracle baresinde besit administration biliklerini menimseyib esas Development-e guc vermelisen. Yeni SQL ve PL/SQL dillerini advanced seviyyede menimsemelisen

    Bu berede kitablar coxdu. En tovsiye etdiyim kitab, “PL/SQL by examples” kitabidi (fourth edition). Web-den pdf versiyasini tapib oxuya bilersen.

    O ki qaldi praktika meselesine, bu umumi bir problemdi. Tek bizim olkede yox, butun dunya olkelerinde demek olar ki beledi. Sen menim sene tovsiye etdiyim kitabi tap, oxumaqa bashla. Orada olan butun misallari ozunde tetbiq et. Sonra her hansi bir sirketde PL/SQL isine uyqun olaraq Junior isci kimi ise bashlayib gelecekde istedyin praktikani yiqacaqsan

    Hi,
    Excellent Blog !

    Basically I m pursuing BE Computer Engg. , and I have lot interest in Database, Datawarehousing & Data Mining.
    I want to pursue my career in DB Administration or Warehousing.

    Q.1 : Is BE + OCA sufficient for starting career in databases ?
    Or are there any other courses that can help me get into Dataware housing ?

    Q.2 : What is scope as fresher ? What things I need to consider for getting entry level job as junior DBA ?

    Thanx for ur help in advance.
    Hope ur advice helps me brighten up my future…..ofcourse as DBA

  13. Dear Tanny

    I think that you’ll start your Oracle career as a Junior DBA. But one thing should be mentioned that administering VLDB (Very large database – data warehouse) and OLTP systems are different. So you need to make a decision for that.

    I’d suggest you to read documentation, read some certification books and practice, practice and practice

    Good Luck !

  14. Tanny said

    Thanx a lot sir…..!

    Just one more thing…can u suggest me some books which can help me for practicing at home as I have opted for self-study mode….

    Or should I continue with certification books from oracle press ?

  31. Samuel said

    Dear Mr. Kamran Agayev,

    Nice to know you, i’m from indonesian. Would you like to help me…I have problem with my oracle database. My Server harddisk was broken but i can recovery the data back. I have installed new OS and oracle 10g in new harddisk. Can I replace the datafile with my old datafile ?

    Thank you sir

    Regards,

    Samuel Eric T

  32. Dear Samuel
    If you have RMAN backup you can perform disaster recovery and recover the database on the different server. Look at the following video tutorial:
    https://kamranagayev.wordpress.com/2010/03/29/rman-video-tutorial-series-performing-disaster-recovery-with-rman/

    Moreover, you can rename datafile using ALTER DATABASE RENAME FILE in the MOUNT stage
    Good Luck

  33. Eric Tololiu said

    Dear Mr. Kamran Agayev,

    Hello sir, would you like to help me ? When I connect to oracle 10g by TOAD or connect by sqlplus, I got this message :
    ORA-01578: oracle data block corrupted (file # 1, block # 38557)
    ORA-01110: data file 1: ‘c:\oracle\product\10.2.0\oradata\orclkdi\system01.DBF’

    I have no backup for system01.dbf datafile. Can you give some information to fix it ?

    Thanks you very much.

    Regards,

    Eric Tololiu

  34. Dear Eric

    Why you don’t have backup of the SYSTEM tablespace? Don’t you know that if you lose the SYSTEM tablespace without having its backup, it means that you lost your database at all! Be careful and take dailiy backups (I hope you’re currently running on the test db)
    If you haven’t backup of the database and you got a Data Block error, use DBMS_REPAIR to mark the block corrupted. For this, you need to create a REPAIR_TABLE using DBMS_REPAIR.ADMIN_TABLES procedure. Then use CHECK_OBJECT procedure to look for the corruption and update REPAIR_TABLE. Then use SKIP_CORRUPT_BLOCKS to tell Oracle to skip the corrupted blocks and use FIX_CORRUPT_BLOCKS to mark the block as a software corrupted

  37. Hi dear Tausif

    If you want to be an Oracle DBA, you need to read a lot and practice everything you read. I’d suggest you to start reading documentation (Concepts and Administrators Guide) from http://tahiti.oracle.com address. Next, install Virtual Machine, Linux and Oracle and start practicing what you read (you can use my video tutorials as well)

    Moreover, read the following .doc file written by Tonguc Yilmaz
    http://tonguc.files.wordpress.com/2009/06/oracle-introduction-for-newbies.doc

    Good Luck!

  39. Dear MadhanKumar

    Sure, it’s your duty to create such objects, to make logical db design and etc. as a experienced DBA

    So I’d suggest you to read basics of Relational Database Systems

    Salam Kamran bey. Size bir sualim var. Neye gore bizim sizin kimi, Teymur Haciyev ve digerleri kimi Oralce uzre mutexessislerimiz ola ola yerli kurslar xaricden mutexessis devet edirler? Mence onlara az pul vermirler. Hemin pulu bizimkilere versalar(meselen size) daha yaxsi olmaz?

  41. Salam Rovshan

    Oracle Approved kurslarinda ders demek ucun kursdan asili olaraq 3-5 gun ard arda 6-8 saatliq ders demek ucun vaxt lazimdir. Shexsen men, hal hazirda calisdiqim shirketde (AzerCell) kursda ders demek ucun bu qeder vaxtliq icaze almaqim qeyri mumkundur. Ancaq onu da qeyd edim ki, bir il once bashqa shirketde ishlediyim halda bu vaxtim var idi, SoftLine-a bunu teklif etdim, cox sevindiler, lakin mesele yene hell olunmamis qaldi. Sebebini mence hec ozleri de bilmir …
