Why  DB link ?

Hi all,
We are trying to access the other DB (target) view information in a VB code .
There are two ways
1. DB Link in source DB and acess using source DB connection in VB code.
2. Access the view using target DB connection in VB code.
Which is preferred ? and target DB is not remote and the two DBs are not related but just sharing information (one-way/read/target to source).
Does DB link add any additional performance challenges (memory/sessions ) as we already have a big source DB ?
Does links creates temp tables/views in source DB ?
Thanks

Whatever is easier for you.

  • Why are Links and forms not working in mobile safari?

    Why do links and forms on the site I am designing not work in mobile safari? They work fine in desktop browsers.
    The controls change state when focused, so it's not that they're being blocked, they simply don't activate. Behavior tested and observed on iPad running iOS 6.1.2 and iPhone running iOS 7.0.2.
    Reference: http://gilli.co/test.html

    I had the same problem but I just found a solution. Siri mistakenly suggests to enable reminders (which you should), but the setting that enables all these, is under System Services (on the bottom of the page) -> Location Based Alerts. I had deactivated it alleviate battery problems and had forgotten about it. Hope this helps!

  • Why the links are still opened in new windows?

    Why the links are still opened in new windows even I selected the option to open in tabs?
    This is one of the web I am reading (sorry that it is in simplified Chinese), I have no problems reading it in tabs in Firefox:
    http://www.sodu.com.cn/mulu_30498.html

    Hi,
    How are you trying to open the windows? Safari does not default to opening new windows in tabs. It can open +external application+ links (e.g. from your email program, RSS viewer, etc) in a new tab, but not links from an existing website.
    To open links in a new tab, you'll need to hold the ctrl key and click the link, or use the middle-mouse button if your mouse has one (or right-click on the link and choose to open it in a new tab).

  • Why does "Link Media" behave differently when used as a keyboard shortcut vs when right clicked???

    Not sure whether anyone else is encountering this, but the "Link Media" command behaves differently when right clicked as opposed to when used as a keyboard shortcut.
    When you right click to select that option for an offline file, you get only the corresponding disconnected source media. But when you execute "Link Media" via a keyboard shortcut, PP brings up a huge list of all other offline media. Why does it only do that when you use the keyboard shortcut for "Link Media" but not when you right click "Link Media".
    I'd like to get the Link Media command to behave via the keyboard shortcut the same way it behaves when right clicked. I don't want to have to deal with relinking a hundred other files, but just the single offline file I'm working on.

    Among the alternatives not mentioned... Using a TiVo DVR, rather than the X1; a Roamio Plus or Pro would solve both the concern over the quality of the DVR, as well as providing the MoCA bridge capability the poster so desperately wanted the X1 DVR to provide. (Although the TiVo's support only MoCA 1.1.) Just get a third-party MoCA adapter for the distant location. Why the hang-up on having a device provided by Comcast? This seems especially ironic given the opinions expressed regarding payments over time to Comcast. If a MoCA 2.0 bridge was the requirement, they don't exist outside providers. So couldn't the poster have simply requested a replacement XB3 from the local office and configured it down to only providing MoCA bridging -- and perhaps as a wireless access point? Comcast would bill him the monthly rate for the extra device, but such is the state of MoCA 2.0. Much of the OP sounds like frustration over devices providing capabilities the poster *thinks* they should have.

  • Why do linked images resize in ID after being edited elsewhere?

    We use CS4 to layout full colour test papers and text and images files are linked from InCopy, Illustrator and PhotoShop. We noticed that if the images or the text is edited outside of ID, when ID is launched the images always shrink to say between 97- 70%. Even if the linked InCopy file is opened and closed without and editing, the images shrink or get clipped on the sides.
    We’ve played with the setting in ID where we decide whether we want linked images to fit in pre-determined image placeholders but this doesn’t seem to fix the problem. Is there a way of ensuring that images retain their original size and dimensions?
    Would be glad to hear of some useful insights on why this is happening. I hope my question makes sense.

    Have a look to your Object Styles of the used frames. Is there something defined in the frame fittings options?

  • Why use link-local addressing for HSRP in IPv6?

    I have scoured the internet for an answer to this question, and am no closer to having it answered.  Am hoping someone here can help!
    * Why do we use link-local (or autoconfig) addresses for the standby IP in FHRPs?  If you are forwarding a packet towards a link-local destination address, wouldn't the source address then have to be a link-local address from the same prefix, which according to scope, should not route beyond the local link?  How do you route an IP packet that has a link-local address for a source address?
    Any insight would be much appreciated.
    Thank you in advance.

    Dougles,
    next hop is used for reaching "gateway" that know where to send packets farther (read it as "next hop to the destination")... routing in IPvX is hopping between nodes where every hop is closer to destination... This is theory behind.
    So as machine that needs to send packet to "not directly connected destination" you only need to send packet to gateway leading to this destination...
    so you need to send packet so, that "gateway" will recieve this packet and gateway then send this packet farther... it is not important what IP address this gateway has.
    On ethernet you only need to know MAC address of this gateway and you send packet (with your source IPv6 address and intended destination IPv6 address) encapsulated with "destination MAC address" of gateway. When gateway recieve ethernet frame, and this frame is for it (destination MAC address is its MAC address), the gateway will proceed IP header (inside IP header the gateway see IT is not final destination for this packet, and gateway will route this packet).
    So configuring IP address as next hop is just "hleper for simpler administration".. MAC address of gateway is important. In IPv4 address resolution protocol (ARP) is used to automaticly get MAC address of gateway if you configure next hop as IP address. In IPv6 there is neighbor discovery protocol(ND) used for this task.
    conclusion: you can use link local address as nex hop address for addresses from any scope ... next hop is just next hop, it is not used just for the same scope communication.
    And question is... if we need just information about MAC address of gateway, why to ask using global address?
    We need to get MAC address... that is information important just "locally"... so to ask for local information, why not use link local address ?
    HSRP is the same case... really just need MAC address to send packets correctly.

  • Why database link can't work?!

    I have two machines: One with Oracle 8.1.5 Enterprise on NT
    (Login user is test1/test1@nt),
    the other with Oracle 8.1.5 standard edition on ScoUnixware 7.1.1
    (Login user is test2/test2@unix).
    I created a table named aa on NT, a table named bb on Unix.
    Then, I created two database link:
    connect test1/test1@nt;
    create public database link link2
    connect to test2 identified by test2 using 'unix';
    connect test2/test2@unix;
    create public database link link1
    connect to test1 identified by test1 using 'nt';
    After I successfully created two database links.
    I run the following SQL script:
    connect test1/test1@nt;
    desc bb@link2
    (This SQL return error:
    ORA-02085: database link link2 connect to ora2
    (ora2 is SID under unix)
    connect test2/test2@unix;
    desc aa@link1
    (This SQL return correct result.)
    Why?!
    null

    This does not appear to be related to sql server, so posting to an access forum would likely be more effective.

  • Why are linked documents randomly out of sync with source docs?

    Regarding RoboHelp’s Link to Word feature…
    I have a RH 9 HTML project on my local drive with several hundred help topics that are “linked as references” from Word documents on a network drive. All was well until recently… several of the linked help topics are showing as “out of sync” even though the source documents have not be changed or moved. The out of sync topics all seem to be randomly picked, and when I update one topic to get things back in sync, another topic appears out of sync. It is not project specific, because I created a new project and created links to the same Word documents and the out of sync issue happened again. I tried removing the cpd file and opening up the project so that a new cpd file is generated, but the problem persists.
    Any thoughts on why this is happening? Is it some sort of connection issue?

    Hi, I understand about the mismatch…the problem is there shouldn’t be any mismatches, because the source documents didn’t change at all, and no updates were made to the html help topics in RoboHelp. The mismatches appear for no reason that I am aware of. They are very random and I can “fix” the mismatches by performing an “update” for a few linked topics, but then a few more mismatches randomly appear.
    I don’t use a Master Page…can you think of anything else I should look into?
    Thanks for your help.

  • Anyone know why pdf links won't open? also- malware has hijacked the downloadable file available when clicking on Adobe's file:

    Changed OS to Mavericks & pdf links from websites won't open. I also had private browsing on  in safari.
    I have acrobat 10.1.10.  I tried to update it when prompted  by auto-updates and it said it can't because  the product has been changed since installed. that can only be the switch to mavericks osx. But it might have prompted me to get version 11 though I only have version 10 & I did the version 10 update in mid-Sept.
    Then, I tried going to adobe.com, searched "upda" and got a list of the cs items with icons, plus two text only links, one was acrobat for mac and the last one, "Update manager update (Mac OS)". It said it is to "resolve a common issue with Adobe Update manager on Mac OS". I cliucked that and got some bogus file. When I hit the button on adobe's site, it shows that the file name should be Adobeupdatemanager403.dmg or something very similar to that. Instead in the download list /box I got " installjdownloader.dmg"  I clicked it once & saw terms of service in which they will switch you to use only their search engine, serve ads, etc. So luckily I didn't install it.
    Does adobe need to investigate this malware problem? Others might search the way I did.
    Anyway, this all started because after installing mavericks, i can't open any pdfs from the web.
    Can anyone help me? Thank you very much in advance.

  • Why do links in the template change location to 'file:///'...on the pages created from the template?

    Im not sure what I am doing wrong but I am building a portfolio site from a template that I downloaded online.
    The site is working and I am slowly converting it from the template content to the content that I want.
    As I will be editing the site and adding more pages I decided to try and add the Header, footer and main navigation bar as a template with another gallery container and navigation as an option on the template.
    I thought that it was working fine untill I noticed that the links on the pages created using the template are showing as follows,
    instead of the links that were in the template that show as,
    Is this something that will change when I upload the site with the template or have I done something wrong making the links?

    Usually this happens when you don't use a proper Site Definition, or if you have files outside your defined site folder.
    Have you defined your site properly?

  • Why will links in Outlook Express emails no longer open a tab in Firefox?

    Before firefox update, when I clicked a web link in an Outlook Express email, Firefox would automatically open and go to the correct website. This no longer happens. Where do I change the settings?

    See:

  • FireFox 3.6 and Adobe Reader X. Reader X PDFs opened within the browser contain links, which do not work. Anyone got clues on why the links fail and how to fix?

    When we rolled out ReaderX and AcrobatX we uncheck the Diaply PDF in Browser window. OK with IE, but ignored in FireFox (3.6.16). We can live with that except the PDFs have links to other URLs and clicking on them is ignored. Same PDF opened outside the browser the links work fine. FireFox with Reader 9.4.0 no problem. Reader X with IE no problem. I can fix the Display in Browser with a change to firefox.js, but have not figured out how to fix the links when the PDF is displayed within the browser.

    My replies are in Bold.
    Thank you for your response and message.
    1. Are you seeing this problem with all kinds of PDF's or some specific  kinds like secure PDF's (with doc open password or printing  restrcitions), reader extended PDF's or PDF forms.
    This problem is with all kind's of PDF's.
    2. Are you opening a locally saved PDF by doing a drag drop in the  browser or right click and open with IE/FF or directly opening a PDF  hosted on the internet?
    It doesn't matter. However I do it, I see this problem in Firefox, IE & Google Chrome.
    3.  Can you also check the version of the Reader X browser plugin? you  could find it at C:\Program Files\Common  Files\Adobe\Acrobat\ActiveX\AcroPDF.dll. Right click -> Properties  -> Details
    If version is 9.0.x then you could try a clean install of Reader X.
    I have checked it. It's the latest plug-in (though at the moment, I have gone back to Adobe Reader 9.4.1, as I've mentioned before, because I need the reader to be working fine for my work and daily life. I am just waiting for a fix before I try Adobe Reader X again.
    As I've mentioned before, I am seeing this issue ONLY on my Windows 7 Ultimate (Laptop). In the desktop's at work, with Windows XP / Vista, I don't see it. Adobe Reader is working fine, browser integration is fine, the floating tool bar works fine, the right click menu pop' up where the right click is done...I can also save PDF' from the main toolbar at the top and so on...
    I really have run out of ideas.... and I am very surprised that no expert support personnel (if at all there is one) have dropped by or said anything or mentioned anything about this.
    Anyway.... Cheers.

  • Why do links open in new windows, not tabs, even when that option is selected?

    Since update to v. 6 and now 7.01, clicking on links opens a new instance of Firefox instead of a new tab. In Tools\Options\Tabs. I have selected "open new window in tab instead" and it has no effect.
    What am I missing?
    Thanks in advance!!

    Thanks for the post. Unfortunately, while running in FF in safe mode may be doing the trick and thus implies an extension (though not necessarily), I haven't added any new extensions. So it is likely a problem introduced by FF since v. 6 or so. I suppose it could be that the extensions themselves need updating by their creators.
    Regardless it is all very time-consuming and frustrating, especially for something that one would think would be readily fixable.

  • Why would links or search bars on the top half of the page not work on any site when i use firefox but work fine in IE?

    links and search bars on the top half of pages dont work and its not that i click them and they dont work but it wont let me click them its like it doesnt see them

    Recently, the Yahoo Toolbar and the Babylon extension have been reported to cause that problem. They seem to overlap invisibly over the top of the web page display. If you have either or both, uninstall or disable them/it, or see if an update is available that solves the problem.
