Some confusions..need ur answer

1.if my database is in archive log mode and we take cold backups, after succesful cold backup, can i delete all archive logs or not?
2. secondly, if the answer to above question is yes than next day i start working on database again.suppose in afternoon a situation arises for me to restore last nights backup and recover from archive logs till 11 in morning.Last night , the last log archived was 31.
so now will the system ask me all the logs from 1 or just from 31 and onwards upto time of 11 in morning?

1. You can delete archive logs created before a cold backup if you are sure you never have to restore the database to a point in time before this cold backup. You should also make sure that the last cold backup can also be restored.
2. When restoring a database from cold backup to the current point in time, you only need to apply archived redo logs created after the cold backup: in your example required archived logs should start from 31.

  • HT5312 I'm just trying to buy some things on the App Store and they ask me about those stupid Apple ID security questions I mean why do we still need to answer them if we forgot the answer do I wasted 15$ ******  for nothing I mean the money is still

    Someone bought me a itunes gift card and it doesn't work cause this stupid Apple ID ask me to answer the questions I mean hello I'm the only one using it why do I need to answer these question?

    I agree completely; email applications on the Mac lag (and I agree with the OP's frustration with responses as well).
    I also have settled on Mail with Mail ActOn and MailTags; this functionality should be incorporated into the OS. I actually like using Outlook in Win 7 better; it's super easy to connect files, contacts, email and other stuff right from one application. And Win 7 has better preview and tagging built in, better than QuickLook. On the server side we desparately need gmail to use tags, but I don't see that happening. I still prefer the labeling scheme it has over Apple's mail, however. But I also find that it confuses many users (labels vs folders).
    There are also other applications that integrate email functionality, like SOHO Organizer, or Contactizer. Good, but not the email holy grail.
    I'd like to see communications built into the Finder or system, which badly needs an overhaul. It hasn't changed much since the 90's and shows it. Communication, whether it be email, tweets, social media posts, sharing, etc, is such an integral function of all work you do on a computer it should be better, um, integrated into all applications. You should be able to send data from any application to others in a variety of formats without having to go into an email application. Sure, you can now do this to a certain extent with either built-in menu items or services, but it's clunky. For example, when you write something you can either "save" and write to disk somewhere, or "export" in a different format, or maybe "email." All of those choices should at least be part of one dialog; it's just as likely you want to email, post, share or tweet what you just wrote, so just  having a "save" dialog is way outmoded.
    So, yeah, somebody get on this.

  • HT201365 I recently upgraded my Ipadto 'iOS7', I carried out all the instructions,added a 4 digit code and after some confusion understood all the upgrades.

    I recently upgraded my Ipad to 'iOS 7' , after following the instructions and some confusion I added a 4 digit 'code' as requested. After getting used to all the new icons etc.the Ipad worked O.K.
    Later in the day when I switched it back on I was asked to enter my 'code' - which I thought I had done, but by mistake I entered my 'password'. after tapping 'done' the message ' iPAD Disabled' appeared.
    Please can anyone assist me? I am a OAP with limited computer experience.

  • Some confusion in MDM

    Hi,
    I am new to MDM. I have some confusion with MDM:
    1. After "Loading Master data" process data from MDC will be copy (except replicate) to MDS (Staging) or it just some logical links that will be stored in MDS towards MDC.
    2. Before "Consolidating Master Data" process do we need to define some database schema over MDS or it is an automated process.
    3. Apart from consolidation and harmonization within heterogeneous system landscape is there any other benefit associated with MDM 3.0?
    4. Does MDM 3.0 shipment comes with MDC adaptor to connect with SAP (ERP and CRM) system and Non-SAP system (like people soft). To my understanding it does have adaptors for SAP but not for non-SAP system.
    5. Help.sap.com say during initial load from trusted clients (ILTC) process ID mapping information can be loaded directly from the MDC and transferred to the CI. But how can we store ID mapping directly in MDC?
    6. Do we need to have all these component in order to use MDM:
       a. Master Data Engine 3.0
       b. Content Integrator 3.0
       c. BI (BW 3.5)
       d. EP 6.0
       e. XI 3.0
       f.SAP Solution Manger 3.1
    Thanks
    Raj

    Hello Raj,
    answers foryour questions :
    1. After "Loading Master data" process data from MDC will be copy (except replicate) to MDS (Staging) or it just some logical links that will be stored in MDS towards MDC.
    A: The data will be copied, there are no logical links. After the extraction the data exist on the Client-system and in the staging area.
    2. Before "Consolidating Master Data" process do we need to define some database schema over MDS or it is an automated process.
    A: We have to consider different cases:
    Case 1) Extraction of Standard object types like Business Partner: It's not necessary to define some Database schemas, for the MDM standard object types, they already exist.
    Case 2) Extraction of Standard object types, but enhanced by additional fields, e.g BP has some extensions: These extensions need to be defined also on the MDM server, and a regeneration of the Staging are might be necessary. There are tools available to do this.
    Case 3) If you would like to extract your own defined Object types, the object type needs to be defined on the MDM Server (with the Master Data Framework).
    3. Apart from consolidation and harmonization within heterogeneous system landscape is there any other benefit associated with MDM 3.0?
    A: To mention just a few: You keep your data in sync also in the future, Global Spend analysis can be done across systems, one stop Data Maintenance.
    4. Does MDM 3.0 shipment comes with MDC adaptor to connect with SAP (ERP and CRM) system and Non-SAP system (like people soft). To my understanding it does have adaptors for SAP but not for non-SAP system.
    A: For the available adapters please look in the  MDM Master Guide. Adapters for third party systems are/can be provided by our partner community.
    5. Help.sap.com say during initial load from trusted clients (ILTC) process ID mapping information can be loaded directly from the MDC and transferred to the CI. But how can we store ID mapping directly in MDC?
    A: The ID mapping is not stored in the MDC, it's stored in the CI. The data is only extracted from the MDC's. Regarding key-mapping from an MDC perspective, there are no changes compared to the normal load.
    6. Do we need to have all these component in order to use MDM:
    a. Master Data Engine 3.0
    b. Content Integrator 3.0
    c. BI (BW 3.5)
    d. EP 6.0
    e. XI 3.0
    f. SAP Solution Manger 3.1
    You're right, with the exception of the SAP Solution Manager. Solution Manager is higly recommended in an MDM installation, but you can run MDM also without. Without e.g. customizing ID mapping would need to be done manually, which can be a major effort.

    Does anyone know if there's a way to change the questions themselves?  (Frankly, they have to be the most ridiculous security questions I've ever seen.  A good security question should be one that you'll have no problem remembering the answer to, even if you're asked years later.  To answer one from the third batch, I'd have to make something up, which makes it unlikely I'll remember the answer later.  And I certainly don't want to have to write the answers down somewhere.)

    My form has a list of yes or no questions.  I want to use either cheboxes or radio buttons.  Unfortunatly I can't make it work.  When I check yes for one question, it marks all yes answers for all other questions.  If I mark some radio buttons to answer, it unmarks later.  Need immediate help!!!

    Is it that you are using a PDF-based form? Did you copy and paste the Yes/No fields all the way down your form? If so, then all of the yes/no boxes are copies of each other and have the same name and properties in the PDF.
    For example, if you had:
         Question 1 and Question 1 Yes/No checkboxes
         Question 2 and Question 1 Yes/No checkboxes
         Question 3 and Question 1 Yes/No checkboxes
         Question 4 and Question 1 Yes/No checkboxes
    Then whatever answer you selected in Question 1 would populate down through the rest of the form.
    Changing the Yes/No field properties in questions two through four would eliminate the problem.
    I hope that helps,

  • "Some photos need to be prepared to view them at full size" message when starting slideshow

    I'm pretty new to iPhoto so I'm sorry if these questions are obvious to you, but they're not to me!
    From the "Photos" section on iPhoto, with no photos selected, I accidentally started a slideshow with all my photos by pressing the play button on the keyboard and got this message:
    "Some photos need to be prepared to view them at full size. Do you want to continue using the current size or prepare the photos so that only full size images are used? This may take some time." With these options: Cancel / Prepare Photos / Continue Playback.
    I pressed "Esc" on the keyboard and it clicked "Prepare Photos" instead of "Cancel" as I expected, it started the process and I clicked "Cancel" to stop it, and the slideshow started. When the slideshow was playing, everything froze, I pressed cmd-alt-esc, no window appeared and iPhoto quit immediately. Could it have caused damages to the library? Could it be a reason to restore the iPhoto Library from Time Machine? I didn't get any error message when I reopened iPhoto.
    Not to leave the process incomplete later I decided to start another slideshow and this time I clicked "Prepare Photos" and let it complete the process. Now when I start another slideshow I don't get that message anymore.
    I have no idea what this process did to my photos and couldn't find an answer anywhere. This library is very important to me, so I'm wondering if I should restore the iPhoto Library from a Time Machine backup.
    Could canceling the process the first time have caused any damage to my photos?
    What is this preparation? What did it do to my photos? Have my photos been resized, or somehow modified?
    Thanks

    Ok, thank you very much. I still don't know exactly what the "preparation" did to my photos but now I guess that nothing bad happened. Thanks

  • Some confusion about 3D TV's and Syncing Glasses

    There has been some confusion about our ad from last week and the offer to sync the 3D glasses with your TV. 
    We by no means intend to confuse our customers or offer fraudulent services.  The offer is new to our stores, and our own employees have been in training just this week.  Let me clarify the services included with the Samsung 3D TV offer that appears in this weekend’s insert. Geek Squad will:
    Set up and connect your TV + up to 5 components.
    Add internet connectable components to your existing wireless network.
    Make sure your 3D glasses work.
    Review and teach you how to use all of your new gear.
    We have some customers who aren’t quite sure how the 3D glasses work, or that the glasses automatically sync with their new 3D TVs.  So this informs them that they can depend on Geek Squad to answer their questions during installation and set-up. There is no additional charge for this – and the Geek Squad 3D installation and networking services are included in the total price of this offer.
