difference between roll back and the rollback segment.

Hello


10.2.0.1.0 Oracle

What is the difference between reverse and cancel segemnt? they are an and even according to the change of version of oracle? Help, please

Hello

The two become the same functionality, but in oracle 9i they did simplify, because if you use rollback segments, you need to put them online in init.ora, and you must take care of management of space etc..
so, they introduced in oracle 9i, tablespace undo you can creage undo segments and space management will take care of oracle managed files, so its reduced the load of s/n

Kind regards

  • Quick question: what is the difference between graphic elements and the movie?

    What is the difference between the two symbols: graphics and movie clips? They both contain frames... ?

    video clips can be

    instance names: so they can be ordered through actionscript

    applied filters: drop shadow, glow, blur, color adjust etc.

    applied of blending modes: difference, screen, lighten, Darken, etc..

    3D transformations

    graphics card:

    None of the above

    the practical reason only to use a graph is the reason jdehaan said. an internal animation graphics can be rubbed through the main storyline. graphics will move forward only when the main scenario for advances. When the main timeline stops... Graph stops.

    clips on the otherhand are supposed to run independent of the main timeline. so you can have a timeline of the HAND with a single frame and inner movieclip animation will work constantly.

    also, via the properties panel, you can tell a graphic to get stuck on a certain range or a set number of times in a loop.

    Always use some movieclips unless you have a reason not too. as kglad said it will save you and other very difficult in the future.

  • What is the difference between this forum and the forum of mosc?

    If you are MOS, then it is easy to get directed to the whole of the MOSC forums. What is the difference? Almost accidentally, I posted a question

    in mosc. The problem is that I have done in the past and got spammed into oblivion with my e-mail address of work for years. I can't tell how

    You can tell whether those email address will reveal or not. Never again!  But anyway why 2 sets of for one?

    I can't speak for all spam you may or may not have been given, but I can briefly describe the difference.

    Communities of MOS (MyOracleSupport) is mainly controlled by the members of the Support of Oracle (and other Oracle employees) and customers.  Access by the employees is reserved for customers with access to Support (MOS).  Thus, when you publish in MOSC responses usually come to an employee of Oracle or a paying customer of Oracle.

    The OTN Forum is open to the public.  The feedback you get here, from someone like me (an Oracle Product Manager) or any employee of Oracle, Oracle customers, previous clients Oracle, students, teachers, consultants, people who like to just help with technical questions, people wanting to be malicious and lawyers.  We are trying to stop the last two as quickly as possible.

    Just for the record, I watch the two Forums, but I focus more on this external one.  If my input is necessary to MOSC, one of the support team will be usually contact me and ask me to comment if I missed something.

    My hope is that by focusing my attention on this external forum, I can better gasoline which uses the product, which is new to the product, which versions are used, what features are more desirable, and what problems are most often.  It also gives me the opportunity to propose corrections to erroneous information and rumors.

    Related, but as my comment about "..." problems often encountered... ", as a result of the feedback mentioned in our last poll, I'll make a mini session at OOW14 (at the booth of DemoGround forms - time TBD soon) which will cover the WebUtil configuration.  In this informal session of 30 minutes, I'll show how quickly and easily WebUtil can be activated and form WebUtil demo in minutes.  There will be some other mini-sessions, but I thought that you would be interested in it.  Details coming soon...

    Hello

    We have a page with the button Save and apply button (R12). I need to know the different behavior between the two. However, I don't see that in the xml definition page saying:

    Standards of UI "Save" button.
    Button 'Apply' UI Standards

    where can I see how the two buttons were addressed in the code? Any doc for standard implementations?

    Thank you!

    Hi Michelle

    where can I see how the two buttons were addressed in the code?

    You can open the page controller & check that how these buttons are processed here...
    In general,.

    pageContext.getParameter("btnId");//btnId is the ID of your Save/Apply Button

  • What is the difference between div class and the id of the div

    I managed to achieve a css colum two in my content.  I usually use "div id" but when I did my two columns he worked (for me anyway) if the content was a 'class' and a 'div' of the content of the right.  Why is this? Is this bad?

    This is my code

    . Happy {}

    height: 400px;

    Width: 300px;

    Width: 694px;

    background-color: #0FF;

    float: right;

    height: 400px;

    }

    If I try to have content like "id", he disappears.

    Thank you in advance.  Karen

    A class is reusable as many times as you want per page.  An ID is a unique name that can be used only once per page.

    {#IDName}

    . ClassName {}

    I'm unique!

    I am re-usable.

    Hi Navin,

    TIMESTAMPDIFF function first determines the timestamp component that corresponds to the specified interval setting. For example, SQL_TSI_DAY corresponds to the day component and SQL_TSI_MONTH corresponds to the component "month".

    If you want to display the difference between two dates in days using SQL_TSI_DAY, unlike butterflies SQL_TSI_MONTH and so on...

    hope you understand...

  • Difference between classic App and EPMA Appl

    Hello
    I am very new to hfm...

    So could you explain on what is the difference between traditional Application and the Application of EPMA.
    In which case we will create these applications.
    What is relative to the uses of Applications as well?
    How do we create EPMA Application? What application is generally more flexible?

    Published by: 809370 on December 6, 2010 05:24

    Hello

    The fundamental difference is that you would be able to share dimensions between applications through EPMA. If you have a planning application and a HFM app and they both use the same size, so you have no need create the dimension twice in EPMA. You can share the dimension between the two applications. 'Dimension library' allows youto this.

  • What is the difference between Foglight JavaEE and Foglight JMX monitoring?

    Hello

    I have a plan to monitor the 6.1.0.17 WebSphere Application Server (32 bit) and 7.0.0.5 (64-bit)

    But I understand not all Foglight for JavaEE and Foglight for JMX.

    Foglight for JavaEE or Foglight for JMX is able to monitor WebSphere?

    What is the difference between Foglight JavaEE and Foglight JMX monitoring?

    Thanks in advance

    Jeans

    Just to add to the excellent answers already posted.

    We have 2 agents which allows you to monitor Java:

    1. a JavaEE agent that runs inside the JAVA virtual machine and the information of both JMX and instrumentation.

    This Agent will give you JMX information like information of JVM (use of the bunch, son etc.), of the Application and server availability information and other information of JMX/PMI (connections pools, pools of ejb, servlets, jsp, JCA and more).

    Java EE & # 039agent also gives you information of the instrumentation - RFA count and response time, exceptional output and timeout information, distribution of queries (App/DB, component technology, server, application failure), object tracking, transaction flow and stransactional between servers and data sources) and ask traces (the ability to see the trees of the RFA at the method level to know where things are slow/stuck).

    2 JMX agent is running outside the JVM but can run on the same computer or on a remote computer, this agent requires access active, JMX. This agent gives you information JVM, availability server/applications, as well as some data as the application server published using JMX (pools of connections, JCA, EJB, servlets, etc.). The JMX agent also gives you the ability to see a list of the mbeans, get the data they expose (javaEE agent gets only a predefined list (same list that is used as a template for the application servers in the JMX agent)).

    Hope this helps

  • What is the difference between. MHT and. HTM?

    Original title: is anyone know about MHT files?

    What is the difference between. MHT and. HTM?

    Hi Sheryl,

    Welcome to the Windows 7 community!

    I understand that you would like to know the difference between file MHT and HTM file. I'm happy to help you.

    MHTML, short for MIME HTML, is a format to archive web page used to combine resources that are usually represented by external links (such as images, Flash animations, audio files, Java applets) as well as the HTML code in a single file. The content of an MHTML file is encoded as if it were an email message to HTML, using the MIME type multipart/related. The first part of the file is normally encoded HTML; subsequent parts are additional resources identified by their URL original and encoded in base64. This format is sometimes referred to as MHT, after the suffix .mht given to these files by default when created by Microsoft Word, Internet Explorer or Opera. MHTML is a proposed standard, distributed in an edition revised in 1999 as RFC 2557.

    HTML Web page that is used by Web browsers; contains the code markup that is stored in a plain text format; used to display and format the text and images in a Web browser.

    HTM files serve the same exact than purpose. HTML files. The extension ".htm" appeared with the use of the Web Microsoft, such as FrontPage, SharePoint Designer and Expression Web development software.

    HTM files are much less common than HTML files.

    It will be useful. For any other corresponding Windows help, do not hesitate to contact us and we will be happy to help you.
