  22. nagesh Says:


    I am new to DBA, According to my knowledge a SYSDBA having the access of viewing the all the tables, my doubt is, can we restrict the DB administrator on viewing the perticular table.

    eg: I want to restrict salary table, so is it possible,if yes how?

  23. nagesh Says:

    Hi kamran)

    I have a small doubt, that a sysdba has full access to the database(objects) but my requirement is can I block the access to a particular table from the sysdba user.

    if yes how ?

  24. Kamran Agayev A. Says:

    Hi Nagesh

    For this purpose, you need to use Oracle Audit Vault

    Hi Aviiesena

    I don’t think being an Oracle ACE is a factor of getting a job, however, being an experienced DBA is the key factor of getting a job :) So don’t give up and start learning Oracle!

  27. Aviesena Says:
