  • What is the best approach for combining events?

    When I work on a wedding my current workflow involves creating a compound clip for each section of the video (e.g. reception, ceremony, dancing etc). Then I add the compound clip 'sequences' into a single project to add the chapter markers and export to a single master file.
    I like the idea of managing each section in a project rather than a compound clip now that projects are part of the library in 10.1, but is there a good way to combine multiple projects (for each section) into a single master project, or would I still need to copy the contents of each project and paste in the master project?
    Maybe I am best to continue with my current workflow.

    Just saw the discussion title - should have said "What is the best approach for combining projects"?

  • What's the best approach for handeling about 1300 connections in Oracle.

    What's the best approach for handling about 1300 connections in Oracle 9i/10g through a Java application?
    1.Using separate schema s for various type users(We can store only relevant data with a particular schema.     Then No. of records per table can be reduced by replicating tables but we have to maintain all data with a another schema     Then we need update two schema s for a given session.Because we maintain separate scheama for a one user and another schema for all data and then there may be Updating problems)
    OR
    2. Using single schema for all users.
    Note: All users may access the same tables and there may be lot of records than previous case.
    What is the Best case.
    Please give Your valuable ideas

    It is a true but i want a solution from you all.I want you to tell me how to fix my friends car.

  • What are the best approaches for mapping re-start in OWB?

    What are the best approaches for mapping re-start in OWB?
    We are using OWB repository 10.2.0.1.0 and OWB client 10.2.0.1.31. The Oracle version is 10 G (10.2.0.3.0). OWB is installed on Linux.
    We have number of mappings. We built process flows for mappings as well.
    I like to know, what are the best approches to incorportate re-start options in our process. ie a failure of mapping in process flow.
    How do we re-cycle failed rows?
    Are there any builtin features/best approaches in OWB to implement the above?
    Does runtime audit tables help us to build re-start process?
    If not, do we need to maintain our own tables (custom) to maintain such data?
    How did our forum members handled above situations?
    Any idea ?
    Thanks in advance.
    RI

    Hi RI,
    How many mappings (range) do you have in a process flows?Several hundreds (100-300 mappings).
    If we have three mappings (eg m1, m2, m3) in process flow. What will happen if m2 fails?Suppose mappings connected sequentially (m1 -> m2 -> m3). When m2 fails then processflow is suspended (transition to m3 will not be performed). You should obviate cause of error (modify mapping and redeploy, correct data, etc) and then repeat m2 mapping execution from Workflow monitor - open diagram with processflow, select mapping m2 and click button Expedite, choose option Repeat.
    In re-start, will it run m1 again and m2 son on, or will it re-start at row1 of m2?You can specify restart point. "at row1 of m2" - I don't understand what you mean (all mappings run in Set based mode, so in case of error all table updates will rollback,
    but there are several exception - for example multiple target tables in mapping without corelated commit, or error in post-mapping - you must carefully analyze results of error).
    What will happen if m3 fails?Process is suspended and you can restart execution from m3.
    By having without failover and with max.number of errors=0, you achieve re-cycle failed rows to zero (0).This settings guarantee existence only two return result of mapping - SUCCSES or ERROR.
    What is the impact, if we have large volume of data?In my opinion for large volume Set based mode is the prefered processing mode of data processing.
    With this mode you have full range enterprise features of Oracle database - parallel query, parallel DML, nologging, etc.

  • What is the Best Approach for System Defined Fields and Default values

    Hi ,
    Please let me know that what can be the best approach for providing a Default value for the System defined fields when creating a User and How can we hide the System defined fields at the time of User creation

    You cannot provide default values for any attributes defined in the FormMetaData.xml file. You can only provide default values for fields defined in the User Defined Fields and supply a default value.
    You can using entity adapters to populate some of the values, but you must supply an Organization because there is an entity adapter that you cannot modify that verifies the organization name.

  • Which one is the best approach for responsive UI development option in SharePoint 2013

    Which one is the best approach for responsive UI development option in SharePoint 2013
    Device channel or responsive UI (HTML, CSS)?

    In practice you're probably going to end up with a combination. A couple of device channels for classes of device and then responsive UI within those channels to adjust to particular devices within the classes.
    Of course the real answer is as always 'it depends' as you'll need to pick the best option for each client based on their needs.

  • Is Rh the Best App for Managing 41 manuals, with many pages being the same?

    I'd like to automate a labor intensive task that I will soon be assuming. We have 41 install manuals for an automotive accessory that fits 41 different models of vehicles. The current manual is 28 pages with at least 24 pages being identical. The documents are done in Word, along many pictures and drawings. When the document is finished, it is converted to a PDF and sent with the item. The pdf is also made available online for folks who may need the electronic version. When we change one page that is common to all, we have to manually update each Word file and then convert it. As you can imagine, the manuals don't get updated and corrected as often as they should
    Since most of the pages are the same, I would like software that can manage changes to these pages and automatically update all manuals. For example, if a change is necessary on page 6 and 34 manuals use this page, I simply change one page and the software "exports" this new page to all affected manuals.
    1) Would Rh do this?
    2) Would it be the best choice for this task?
    3) If Rh is the best choice for this, what is the best approach for beginning this task? Get a book and read or just jump in?
    4) I came across a book written by a firm called GooberGuides, is this a good resource? Do you recommend a better one?
    5) Does my project require a special technique when setting it up in an app like Rh or is the process fairly intuitive? I don't want to waste time by implementing this incorrectly, only to start over again when I realize there was a better way.
    I would be very grateful for any guidance you could provide.
    Thank you.
    Rodger

    I don't think your questions were answered, except for the tool one, which is not the most important one. I would reverse your questions:
    Does my project require a special technique? Yes! Single sourcing, which is a methodology for developing modular, reusable information, not a tool. Before you even approach a tool, you must analyze your content, define standards for it, define information types (Google for DITA), and convert it from linear (as your Word documents are) to modular.
    I have not seen the GooberGuides book, but I can definitely offer these:
    Content Managment for Dynamic Web Delivery - Jo Ann Hackos
    DITA 101 - Anne Rockley, Charles Cooper, and Steve Manning
    Introduction to DITA: A User Guide to the Darwin Information Typing Architecture - Jennifer Linton & Kylene Bruski
    Managing Enterprise Content: A Unified Content Strategy - Anne Rockley
    Single Sourcing: Building Modular Documentation- Kurt Ament
    Tools - obviously since we're on the Adobe forum, Technical Communication Suite must be acknowledged. But you can accomplish single sourcing with several tools. Check out a brief overview of some at http://www.writersua.com/restools.htm.

  • What is the best approach for executing this code only once?

    Hi,
    What would be the best way to this using JSF/Java web architecture? I have a login page, login.jsf, that submits login credentials to another servlet and if successful, is redirected to a login success page, which I have called "main.jsf", my application's main page. What I want to do, however, is when the login success mechanism redirects to my application, I want to run a bit of Java code (which requires access to the session object) that executes only once, and then redirects to my application's main page.
    In other words, I could put this Java code on my application's main page, but then it would execute every time a user visited it.
    Any advice on the most efficient way to do this?
    Thanks, - Dave

    Thanks for your reply but I have a question. If the filter is executed on every page, then, assuming the user is logged in, the code would be executed every time. How can I create this such that my code snippet is executed only once, preferably after the user is re-directed to the login success page?It is more secure. On login just put the User object as attribute of HttpSession and check in the filter if it is there.

  • What should be the best approach for a novice like me?

    Hello everyone.
    Please be patient. I'm new to the Adobe software family and I have a lot to learn.
    But I came here to find out the best way to learn in order to do what I want to do with my business.
    What programs do you think I need to master first? What is the most common approach to someone in my situation?
    Basically, this is what to create:
    electronic forms (to send to my clients, where they provide all kinds of information)
    short and long coaching programs (rich in text and image, sort of like an e-book)
    new logo and brand identity
    poster and decal designs
    In the future.. I'd like to develop my own website.
    This is it. Any help is welcome.
    Thanks,
    Gus

    Adobe.com is a good place to start.  They have resources that you can look into getting more info.  My approach would be to try and find some kind of formal training somewhere in your area.  Perhaps there is a local community college graphics department that has a certificate program.  There are also CD/DVD tutorials, but you need to work with other people and do assignments that are part of a curriculum.  If you decide to proceed on your own, start with Illustrator where you can gain skills in line manipulations that can then be used to help you make selections in Photoshop later on.  So, in my opinion, Illustrator first, Photoshop second, Dreamweaver third, and Flash/Fireworks fourth.  This all will take time.  It's impossible to learn all of the applications in a week or two.  That's why I think you will benefit from a formal setting like a classroom where you can ask questions and learn tips and tricks.

  • What' the best approach for synching a drum machine to AA3

    Hi
    I have recently purchased both AA3 and an Alesis SR-18. I'm wondering how to go about synching the drum machine to AA3. Do I do it via SMPTE or Midi? And exactly how do I do that? Later on I will also need to link my synth via midi to the AA3 sequencer.
    I haven't recorded for many years (reel to reel). Back in those days I would record a code from the drum machine onto the tape. I don't know what to expect now:
    Do I use AA3 to generate a Midi time code, would this be seen recorded onto a track. I'm not having any luck with everything I have tried so far.
    Thanks for any help you can give.

    I am about to attempt this with my Alesis HR-16 and MMT-8 combo.  I used to do the same as you, record a code to tape then play it back to trigger the drum machine and sequencer.  I assume it will work the same but I will have to try it hands on to see if it works.
    Try recording the code to AA, then play it back and see if it runs the Alesis.  Then try recording the Alesis back into AA.  Good luck!

  • What's the best app for a reader type program on the mac air

    looking to use my mac air to read ebooks - any suggestions to the best type application for that
    Thanks

    That would depend on the source of the ebooks you're trying to read. If the ebooks have any kind of DRM, you would need to use the appropriate app (e.g. the Kindle app for ebooks purchased from Amazon). I actually like the Kindle app generally.

  • What is the best approach for a short answer quiz that has a number range as the correct answer?

    Client does not want to use multiple choice questions, so I am trying to figure out the best way to put in a range of numbers for the correct answer.

    I'm doing my best to figure this out, but not finding success in my advanced action. Below is the quiz question and how I setup the advanced action.
    Question: Determine the total heat load for test house 1.
    Answer: 32,120
    Acceptable Answer Range: 30,514 - 33,726

                   If
                        Value1 is greater or equal to 30514 AND

I have not been successful yet in getting the system to add the points in appropriately. Is there another system variable I should be using to add the points to the quiz for reporting to the LMS or am i going about this completely wrong?

  • What is the best approach for patch management

    Hi,
    I'm new about patch management. I would like to ask you how manage patch on few Solaris 10 servers using command line.
    I would like to know:
    1. Using only command line how to download latest patches
    2. There are some dependencies how to check this and install only those patches which meets dependecy requirements?
    3. Is there possiblity to atomate this?
    4. Is it possible to have one patch server and others servers will download and install this patches?
    5. What if some patches are not installed?
    6. How to find out which patches are necessary and which patches don't have to be installed? Or maybe or patches to be installed?
    7. Could you please describe your approach for managing patches? Or maybe you can recommend some books/web page/articles that can help me to understand patch management.
    Thanks in advance,
    Daniel

    smpatch is the command line tool to manage solaris patching. first you need to register yours system - this can be done using sconadm, detailed here:
    http://sunsolve.sun.com/search/document.do?assetkey=1-9-82688-1
    smpatch analyze will list all required patches and resolve dependencies. smpatch download will download all the required patches, and smpatch update will apply them. You can set up a Local Patch Server to download patches, then your clients will download the patches they require from it. This is detailed in chapter 6 of the update connection admin guide

  • What's the best approach for Scrollers?

    Hi, the video says that the <Scroller> element should be declared with height and width (suggested best practice). However the exercise suggests we define width and height on the <Group id="myGroup" width="300" height="300"> and then use <Scroller viewport="{myGroup}" />. Which is the best way? What are the advantages/disadvantages of the two methods?
    Regards,
    Marco

    Can you please post a link to the exercise that suggests doing that?
    It's probably not recommended, but I would have to see what they are doing. 
    There are two ways to size a Scroller... 
    1. Set a size on it and not on the viewport: 
    <s:Scroller id="scroller" width="100" height="100">
        <s:Group id="viewport">
        </s:Group>
    </s:Scroller> 
    2. Set a size on the viewport and not on the Scroller: 
    <s:Scroller id="scroller">
        <s:Group id="viewport" width="100" height="100">
        </s:Group>
    </s:Scroller> 
    But never set a size on BOTH the scroller and the viewport.  This could cause the Scroller and viewport to fight over what sizes they are supposed to be and can cause unexpected behavior. 
    I always recommend #1.  The main reason to use #2 would be if you want the viewport itself to be a specific size and have the Scroller wrap scrollbars around that (so the Scroller might be roughly 120x120 if scrollbars show up).
