Context-Aware Data Redundancy Elimination (DRE) ?

When is this going to be available? I came across it in an article which referenced available in v4.4. I'm running 4.4.1 and I don't see anywhere in the release notes about it. Perhaps it meant v4.5?
http://www.networkcomputing.com/wan-optimization-and-application-acceleration/231700318

Thanks! This was the information I was looking for. Our default policy was set to bidirectional, after the upgrade. I'll have to wait until next year to change it to "Adaptive DRE" (Contex-Aware DRE feature). Hopefully, I'll start seeing the oldest dre data go up from days to weeks or maybe months.
This should work with all TCP application if we turn this feature on across all policies where it was set to bidirectional?
•  Bidirectional DRE: Data chunks and signatures are written to the disk  on both the sender- and receiver-side Cisco Wide Area Application  Engines (WAEs) to provide optimal compression.
•  Unidirectional DRE: Only signatures are written on the sender-side WAE,  and both signatures and data chunks are written the disk on the  receiver-side WAE. In addition to providing optimal compression, this  mode effectively uses the DRE cache for higher scalability.
•  Adaptive DRE: Context-Aware DRE intelligently chooses between the  bidirectional and unidirectional DRE caching mechanism depending on the  type of application traffic.

  • Why we need to conver Context  Node data into XML file----Export to Excel

    Hi All,
    Let me clarify my dought........today i have gone through the concept of  "Exporting Context Data Using the Webdynpro Binary cache" in SAP Online Help.
    From the SAP Online Help pdf document, i have found that, the context node data has been converted first in to XML file,after that file had been stored in the web dynpor binary cache...bla....bla.........
    Here my qtn is why they had converted context node data into XML file. With out doing that can not we export context node data to excel file..?

    Hi Sesshanna,
    it is not neccessary to do that but xml has the advantage, that it can be easily transformed into every output format that might occur in later project stages.
    If it's simply about blowing out some Excel, I suggest using an OSS library such as jexcelAPI or Jakarta POI and building the Excel how you need it.

  • How to make transparancy context-aware when green screening.

    I am using After Effects CS6 about 1 month and face a problem.  I have successfully green screened marionettes so I can place in a video without showing the string, which is also green.  The string did become transparent within the mask but within the marionette body, it just turned brown and moves like string. Question: Does anyone know how I can alter the string to be context aware?

    That could be a tough one; there isn't any way to make a chroma key contextually aware.  You can animate the beginning and ending points of the Simple Wire Removal effect that comes with AE to see if it does an adequate repair job for you.

  • MSE 7.4 Base Location Services and Context Aware Licences?

    Hi! I have a question for MSE Base Location Services and Context Aware Licences. Do I need to add Base Location Services and Context Aware Licences in L-MSE-PAK or just enough Base Location Services Licences? What is the difference in these licenses?
    I know that the Base Location Services license is determined by the number of access points, and Context Aware license is determined by the number of devices.
    Please help me with this issue.

    OK, for example, a customer bought a Context Aware license. Can he activate it in MSE 7.4 or need to install MSE 7.3 with Context Aware license and then upgrade to MSE 7.4?

  • Disappearing context aware tool bar

    Where do I report a bug?
    I've assigned InDesign to a 'Desktop' formerly called 'Space'. Mac Lion 10.7.4 Done via the InDesign icon in the dock. Right click the icon > Options > Assign to: Desktop 2,3, whatever.
    So I've bobbed out of InDesign into Firefox or Mail on a different desktop. When I click the InDesign icon in the Dock to return to InDesign, the screen slides to the space ok, but InDesign appears without the top context aware tool/attributes bar... not sure what it's called but the one immediately below the 'ID' bar in the default 'Essentials' workspace. Blimey, takes some explaining doesn't it. Anyway it's missing - there's a gap across the top of the screen below the 'ID' bar. If I slide (4 finger gesture) to the default desktop, there the missing bar is for the briefest moment!!!! Clearly while the main app is happy to reside in the Desktop/space... the toolbar gets mightly confused.
    If I cmd+tab between applications, it also does it (though I'm not sure it's consistent), but if I use the gesture to move from desktop/space to InDesign Desktop, it seems fine (though I've not tested this rigorously).
    InDesign CS6

    Lots of problems, apparently, with Spaces...
    anyway, you can report a bug at Adobe - Feature Request/Bug Report Form

  • No context aware with Aironet 3500i

    Hi there
    we have an AeroScout installation on a big campus. Some old APs (Aironet 1140) have been replaced by the Aironet 3500i APs and now there are no context aware information (location) anymore at these spots.
    Does anyone know, what the problem could be. I don't believe that it is a licensing problem, or do the Aironet 3500 APs need additional licenses for context aware (additional to the standard WCS Plus and Context Aware licenses)?
    Thanks a lot and best regards
    Dominic

    Hi Nicolas
    I got more detailed information, so I think it is a problem of the partner engine in combination with Mobile View (AeroScout), I will open a case on their support side.
    The clients and tags are all shown on the WCS for all APs (even for 3500i), so the MSE is working correctly. But the tags are not shown in the Mobile View for the new APs. Just as an information.
    I will keep the post updated.
    Regards
    Dominic

  • Context Aware licenses difference for MSE 3310

    Hello
    I am getting a hard time in order to understand the real difference between the two types of context aware licenses for the MSE:
    1 . AIR-CAS-1KC-K9 -  Context Aware License For 1K Clients and Tags (RSSI based)
    2. AIR-CAS-1KT-K9 -  Context Aware License For 1K Tags(RSSI, Chokeponts and TDOA)
    For a regular network without any devices with tags such as RFID, I understand I do not need to get the .2, only .1, even though the .1 also is shared with clients at 1K of each. Also, the .2 does not say clients, only tags and advanced features as TDOA. Going through the Q&A it does not clearly says the difference, when to use one or the other.
    Any ideas?
    Thank you!

    basically the KC license will track Wi-Fi clients, interferers, wired devices and Wi-Fi tags based only on the RSSI value.
    If you need to track your tags via choke points then you need the KT license. KT is only for the tags

  • ASA Context Aware Security (CX) Vs URL filetering (websense)

    Fellas,
    I'm new to ASA and PIX. I have PIX with websense for URL filtering. We are upgrading to ASA 5585-X wih CX context aware module. Will I still be needing Websense, since we have CX. What would be the best soultions? Thanks in Advance.
    Happy New Year!

    This is not a popular thing for a reseller like me to say, but I am not a fan of the CX module.  It does a little bit of a lot of things, but doesn't do particularly well at any of them; that is to say, it is not for example a replacement for a proper e-mail filter or web filter or IPS.
    I would stick with Websense versus moving to the CX module.  I have had a lot of clients try - against my suggestion - to use just the CX module and every one of them has come back to their URL filtering boxes.  With that said, I might recommend trying IronPort instead - it may sound a bit biased coming from someone on the Cisco forums, but I really have found it to be a substantially suprerior platform for most (not all, but most) installations.

  • How to get Context Node data in respective HTM page

    Hello Experts,
    My Scenario is as follws: Two views are there one is table view[contain customer data] and another form view[where i require the data]. my requirement is, table view is having customer information with their city names. i need the city name in my form view's .htm
    Both views are having same context node which are bounded via custom controller.
    Could you help me out to solve this
    With Regards
    SRiNi

    Hi,
    this should be very simple as the context nodes are defined as page attributes on your .htm page.
    Example:
    Your Context node is named /TEST/.
    In your .htm page you can access it by:
    <%
    data:
      lr_property type ref to if_bol_bo_property_access.
      lr_property = /test/->collection_wrapper->get_current( ).
    %>
    EDIT:
    In case there is no page attribute, you can use the SET_MODELS method in the view implementation class to set a variable. Be sure to create the variable you want to set on the .htm page in the page attributes first.

  • Data Source Elimination

    Hi Gurus,
    We have replicated three data sources 0CO_PC_PCP_03, ZCKIS and ZKEKO under the info source 0CO_PC_PCP_10. Now we want to see how the report data looks like without having the data source 0CO_PC_PCP_03 data. Is there a way to proceed by eliminating this data source and just having ZCKIS and ZKEKO, temporarily to see how the data looks like.
    Thanks,
    Sandhya.

    Hi Sandhya,
    When data is successfully loaded to your cube, the requests are always available for reporting (unless there are aggregates that have not been rolled up, or you are reporting off an ODS and the data has not been activated). You can verify this by RSA1 > yr InfoCube > right Click > Manage > Request tab... here you can see all the requests loaded into your cube. The little blue and red icon that you see in the second column (after th erequest number) means that data loaded by this request will be shown in your reports.
    To exclude or inlcude particular request IDs in your query, open up the query in the query designer, and from the Dimension Data Package (the last one), take 0REQUID and put it in the filter or free chars area of your query. Then right click and restrict it by the request IDs whose data you want to see. You can match the request ids with your cube (right click Manage)...
    So either take all the request IDs that are not the 0CO_PC_PCP_03 ones, or take all the 0CO_PC_PCP_03 requests and then exclude (they will look red in the query designer).
    Hope this helps...
