  • Can we make apply  join a column on which VPD policy applied in Oracle 10g

    Hi,
    i am planning to apply a column level security using VPD concept into Oracle 10g
    but i have a one doubt.
    Suppose i am going to apply a VPD policy based on user priviliges on a column DEPTNO in EMP table so whenever a particular user logs in,he will not see the deptno.But he can fetch the data from other table DEPT based on join condition EMP.DEPTNO=DEPT.DEPTNO . Is it possible can we make a join a column on which VPD polciy is applied ?
    pls any idea or thought would be appreciable..
    Thanks in advance
    Anwar

    Hi Anwar!
    I have not tried yet, but I believe that you can do this.
    However imagine the following:
    A user U1 has the right to see some values in the deptno column, but not all. This is fine, and I believe that this is what you want to achieve.
    A user U2 will see no records from the deptno column. This will impact your query, as your emp.deptno = dept.deptno part of the where clause will deliever no records.
    So you have to be careful if this condition could apply and what the impact will be on your software.

  • Steps to export and import oracle 10g databse from AIX to AIX and LINUX

    Hi,
    I need the steps to export the oracle 10g database from AIX server to AIX server and LINUX server.
    Please give me all the steps as this is my first exort an import activity.
    thanks,

    For 10g there exist two ways to do so.
    1) Regular exp/imp.
    2) Data pump expdp/impdp.
    As this is your first export and import activity, relevant concept understanding is mandatory for you.
    Documentation Link
    http://download-east.oracle.com/docs/cd/B19306_01/server.102/b14215/toc.htm
    Read the chapters 1,2,3 (Data pump expdp/impdp) and 19 (regular exp/imp). Good luck.

  • Oracle 10g and Datawarehousing

    Hi,
    I have come across a concept of real-time datawarehousing and learnt that there is a feature in Oracle 10g database which supports it.What are those features of Oracle 10g which support the real-time datawarehousing?
    Thanks

    For example:
    Oracle database 10g Data Warehousing.

    To my mind, full answer for your question (design, features, etc).

  • Preparation for Oracle 10g OCA and OCP exams

    Hi all,
    I am studying for my first Oracle 10g OCA exam. Thus far, I have the Transcender exam prep software and book from Oracle Press for the OCA/OCP exams with Oracle 10g. With a test Oracle 10g database to practice on while I study, am I on the right path?
    Thanks

    Use the http://education.oracle.com OR http://otn.oracle.com as your portal - you'll see the Certification link on either one. From the Certification page you will be able to drill down to the objectives and requirements of the exam. I suggest you use that as a checklist, as the various books and sample exams have been known to include mistakes or miss items.
    In addition, you should be familiar with the first few chapters of the Oracle Concepts manual and also, preferably, the first few chapters of the DB Admin Guide - both available from http://tahiti.oracle.com
    A great motto while learning is "trust no one - verify everything"

  • Oracle enterprise linux and oracle 10g?

    Hey;
    I'm pretty new to trying to download oracle and get it installed on a linux box. I made a couple of attempts on linux fedora core 10 and windows vista home edition both of which didn't get very far. Since I just past my ocp exams via a boot camp (yay for me!), I'm hoping to get a couple of linux boxes up and running to ensure I get the concepts down through practice.
    From what I'm reading, it looks like I can download enterprise linux, put that on a system, and then download oracle 10g and install that w/little or no trouble (at least not expected...)
    Am I reading that right or did I miss something? Any info greatly apprecaited.
    Doug O'Leary

    Hello,
    You can download enterprise linux and 10g and get going. Enterprise linux is pre-packaged for the required components required to install oracle software, here is a link for your future reference to see platform compatibility.

  • What mechanism Oracle 10g use for write (Insert/ Update) and Read (Select)?

    Hi
    What mechanism Oracle 10g use for write (Insert/ Update) and Read (Select)?
    Thank you

    Aren't the answers given in PL/SQL forum sufficient enough?Well, as the first answer in that forum directed the OP to this forum you can hardly blame them for the repost.
    There is some high-level stuff in the Concepts Guide. If that is insufficient the OP will need to tell us what more details they need to know (and perhaps why).
    Cheers, APC

  • Nested tables and multiset operators in Oracle 10g

    Consider the following scenario:
    We have two identical relations R and S defined as:
    CREATE TABLE R(
    a INTEGER,
    b table_type)
    NESTED TABLE b STORE as b_1;
    CREATE TABLE S(
    a INTEGER,
    b table_type)
    NESTED TABLE b STORE as b_2;
    where table_typ is defined as
    CREATE TYPE table_typ AS TABLE OF VARCHAR2(8);
    Suppose we have two instances of R and S, each having one tuple as follows: R(1,table_typ('a','b')) and S(1,table_typ('b','c')).
    I would like to "merge" these two simple instances (e.g., achieve the effect of a simple SELECT * FROM R UNION SELECT * FROM S query) and obtain the following resulting instance: Result(1,table_typ('a','b','c')).
    Would this be possible in Oracle 10g? A simple UNION does not work (I got a "inconsistent datatypes: expected - got SCOTT.TABLE_TYP" error). I also took a look at the MULTISET UNION operator over nested tables available in Oracle 10g, but it doesn't seem to get me anywhere. Any help on this would be greatly appreciated.
    Thank you,

  • Oracle 10G installation problem, and errors on SOLARIS 10 x86

    HI.
    I installed the last version of oracle 10g on a x86 SOLARIS 10 system.
    When the installer arrived at Configuration assistants, the window is stopping, and I can't see forward. But when I look at the installAction.log, the installation is checked as OK (?).
    When I launch sqlplus, and startup inside, it is said the ora-00205 error (problem with control files), and in the end, I'm really suprised there's no the database I told the installer to create at the beginning. But should I be surprised? As I didn't see really the end of the installation, and the installer didn't propose me the PATH where to install the DB, well, I guess there's something wrong.
    Could anybody tell me how to solve these problems, please?
    Thank you :)

    Two options:
    1. Create database using DBCA - execute $ORACLE_HOME/bin/dbca
    2. Create database manually (without DBCA)

  • Displaying both Hindi and Arabic numerals in Oracle 10g PDF report

    Hi….
    Oracle experts told us to ask “In how many ways we can do it in oracle?” instead of asking “Can we do it in Oracle?” , I need ONE way to solve the following problem, it toke to much time and I don’t know if it can be solved !
    The problem:
    Can we print in - Oracle 10g reports - a PDF report with BOTH Hindi and Arabic numerals?
    Well, at design time everything is fine, you can use right-to-left, left-to-right and the print preview is showing BOTH Hindi/Arabic numerals fine, but when I tried to produce it as a PDF, unfortunately its not, means its either all Hindi or all Arabic numerals !
    I tried everything possible, environment variables: NLS_LANG, REPORTS_BIDI_ALGORITHM, and REPORTS_ARABIC_NUMERLS, setting Digit substitution to Context in windows regional settings, uifont.ali is modified properly according to metalink note, but nothing solved this issue!
    I noticed something, when I used the DESTYPE=printer and DESNAME=PDF995 (one of the PDF printers) , it worked fine , means the problem could be in the generic PDF generator of the Oracle reports server,
    But even with PDF995 you still need to feed the file name, which is not suitable for multi-user environment that need the report to be displayed via web browser.
    Does anybody face this before?

  • Need Advise and Suggestions-Oracle 10g

    Hi,
    I have been working on databases as DB developer(mainly PLsql)--Oracle 10g
    Recently,i have joined in a particular position where I have been asked to find out areas where
    improvement is necessary / or areas where improvement or changes would help very much and also gradually implement all best practises avaialable.
    So,could you please help me with these queries
    (1)What are the most important areas that i can start with the database which would impact largely the entire database.How can i start with it? any steps or process
    (2)I had once taken a report out for the expensive SQLs running.But that dint help much...because those SQLs were used temporarily on and off.
    Similarly,what are the other points to be looked on.
    (3)Things which can be replaced with the industry standarad better ones fully.
    an example would be...like.."following a particular naming format,or coding style,etc
    Thanks
    Rohit

    Hi Rohit,
    This is a pretty huge subject. To start, I'd say you need to talk to the business. Talk to the users of the database, cause they are your customers. Get a clear understanding of the most critical business processes. Start with the most critical ones, and get performance profiles. How long do they take to run? What's the customer's perception of the process performance? If it's acceptable, move on to the next one. If it's not acceptable, you'll need to dig deeper. Look at each piece of the process. Where is the most time being spent? Can it be improved? This step will be a combination of process improvement and setting the correct expectation. Often, the user doesn't really know what is realistic in terms of performance. If you have a 2 billion row table that needs to get full table scanned, expecting a response time of a few seconds just simply isn't going to happen. You need to clearly convey that to the customer. On the other hand, at the same time, you should be on the lookout for real improvements. If you can re-write the SQL or add an index, and eliminate the FTS on that 2 billion row table, maybe a response time of a few seconds is actually realistic.
    It's all about understanding the system, and understanding the customer's needs, and how they intersect. It will be an iterative process, and will take some time.
    As to "best practices", I'm not a fan of them. Understand your system, understand your customer's needs, and understand how Oracle actually works. If you can master that, you'll be unstoppable. Note that many, many people, much smarter people than me, have spent a lifetime trying to master those three points... :-)
    Good luck with your new job!

  • Oracle 10g RAC design with ASM and OCFS

    Hi all,
    I have a question about a proposed Oracle 10g Release 2 RAC design for a 2 node cluster.
    ASM can store database files but not Oracle binaries nor OCR and voting disk. As such, OCFS version 1 does not support a shared Oracle Home. We plan to use OCFS version 2 with ASM version 2 on Red Hat Linux Enteprrise Server 4 with Oracle 10g Release 2 (10.2.0.1).
    For OCFS v2, a shared Oracle home and shared OCR and voting disk are supported. My question is does the following proposed architecture make sense for OCFS v2 with ASM v2 on Red Hat Linux 4?
    Oracle 10g Release 2 on Red Hat Enterprise Linux Server 4:
    OCFS V2:
    - shared Oracle home and binaries
    - shared OCR and vdisk files
    - CRS software shared OCFS v2 filesystem
    - spfile
    - controlfiles
    - tnsnames.ora
    ASM v2 with ASMLib v2:
    Proposed ASM disk groups:
    - data_dg for application data
    - backupdg for flashback and archivelogs
    - undo_rac1dg ASM diskgroup for undo tablespace for racnode1
    - undo_rac2dg ASM diskgroup for undo tablespace for racnode2
    - redo_rac1dg ASM diskgroup to hold redo logs for racnode1
    - redo_rac2dg ASM diskgroup to hold redo logs for racnode2
    - temp1dg temp tablespace for racnode1
    - temp2dg temp tablespace for racnode2
    Does this sound like a good initial design?
    Ben Prusinski, Senior DBA

    OK Tim, thanks for advices.
    I think Netbackup can be integrated with RMAN but I don't want to loose time on this (political).
    To summarize:
    ORACLE_HOME and CRS_HOME on each node (RAID1 and NTFS)
    Shared storage:
    Disk1 and disk 2: RAID1: - Raw partition 1 for OCR
    - Raw partition 2 for VotingDisk
    - OCFS for FLASH_RECOVERY_AREA
    Disk3, disk4 and disk5: RAID 0 - Raw with ASM redundancy normal 1 diskgroup for database files.
    This is a running project here, will start testing the design on VMware and then go for production setup.
