      database testing is more like checking whether your database can with standby the transactions that are incoming, load analysis etc. you can take this chance as it will enhance your resume

  26. chinmoy said

    Hi Pavan,

    Please read my explanation & correct me if is there any wrong steps.

    The details is given below,

    Sqlplus scott/tiger@mandb

    SQL>select * from emp;

    SQL>update emp set salary=10000 where empid=5;


    1. sqlplus command is fired, the user process (client) access sqlnet litener.
    2. sqlnet listener confirms that database is open & creates a server process.
    3. server process allocates PGA into memory. Each server process has its
    own PGA area, PGA contains data & control information of server process.
    PGA ( Private Sql area & Session Memory ).
    4. ‘Connected’ message returned to user.
    5. select * from emp;
    6. select statement is parsed into shared pool ( library cache & data dictionary
    cache) , this is called hard parse because the select statement is not already
    present in shared pool. An executable code is generated for select statement
    in shared pool. Server process got the all necessary information for select
    statement before fetch.
    7. server process takes the data from data file , loads into the buffer cache, puts
    into the most recently used(MRU) area & gives the data to the client via PGA.
    8. update emp set salary=10000 where empid=5;
    9. Before update statement , I want to say that empid=5 has a salary=8000
    10. update statement is parsed & executed in shared pool.
    11. server process checks( via PGA) buffer cache for data is available or not.
    12. In our case data is available in buffer cache.
    13. So data is updated into buffer cache with new salary i.e., 10000 & keep
    old copy i.e., 8000 into undo blocks for rollback.
    14. update is placed into redo log buffer.
    15. row updated message returned to client via Server Process(via PGA).
    16. commit;
    17. server process sends a commit to redo log buffer , a SCN is assigned.
    18. LGWR process writes redo buffer contents to current online redo log
    file on disk.
    19. CKPT process updates the header of all control files with new SCN.
    It signals DBWR to write modified blocks (dirty blocks) from buffer
    cache to data file on disk.
    20. commit complete message return to user.
    21. DBWR process writes modified blocks from buffer cache to data file
    on disk & CKPT updates header of the data file with new SCN.
    22. Undo data blocks associated with this transaction are released from
    Buffer cache.
    23. exit

  27. Hi Pavan, I’ve installed oracle10g on Linux-rhel4 through VMWARE-6.5 sucessfully but while creating database manually & connecting to sqlplus its asking for username & password. if I give username sys as sysdba & password as whatever I created while creating d database, but its showing Error as Insufficient Privileges. So how to solve dis Error. Plz Can u help me out on dis….

    • Pavan DBA said

      have u tried with below command?
      sqlplus / as sysdba

      if still getting same error, it means ur unix username is not part of DBA group. check that using “id” command of unix.

    Hi pavan sir,
    I have got an interview question recentely from cts which is is in 11gR2 if we do not configure FAL_CLIENT & FAL_SERVER who is going to fill archives gap fill at standby?

    I said it is mandatory but he said FAL_CLIENT & FAL_SERVER Is optional in 11gR2 and 12c also for this what we need to tell for this sir? could u plz help me this answer

    I am waiting for ur best answer sir………

    • Pavan DBA said

      a part of it is correct. fal_client was deprecated from 11gr2 onwards. but still fal_server is there. u need to mention that.

      • uday said

        Hi sir,
        Awsome sir.I thougt it both are depricated. thanks for ur information. Suppose if we configure FAL_SERVER on standby side, without FAL_CLIENT how archve gap fill? i mean who is going to take the responsibility intimate to RFS from Primary? i got confusing plz tell me how it works……………..

      • Pavan DBA said

        it is FAL process itself.
