How to invalidate cache for a single item?

I m trying to invalidate cache for a particular item in the repository.
I dont want to invalidate the whole cache.
Is there a way to do that through dyn/admin?
TIA

You can create own component in dyn/admin to do this.
1. Create a global component with the following properties
/atg/dynamo/service/GSAInvalidatorService
[repository of item to invalidate]
[itemDescriptor]
[repositoryId]
2. Create method invalidateCache
getGSAInvalidatorService().invalidate(getRepository(), getItemDescriptor(), getRepositoryId());
or, this should work as well
ItemDescriptor someItemDescriptor;
someItemDescriptor.removeItemFromCache(getRepositoryId());
Maybe try them both to see what works for you.

Q: How to disable cache for a single portlet ?

Due to performance reasons I need to set the full page cache. But I have just one custom portlet on the home tab page which will count the logins. But the cache will prevent this portlet from getting the right value out of the DB. It would be pretty sad when I have to disable the full page cache because of this single portlet. I know that there's a way to set cache calls on portlet level. Can anyone shed a light on it. Thanks.

Hi Amjad,
I want to remove cache completely for a portlet. Is there any easy way of doing this. I tried to disable from Administer --> Cache. No luck.
I want to load the page every time from server. Please help me.
Thanks

How can I add the logo image for a single item in an RSS feed?

Hello,
I am an administrator of iTunes U at the University of Minnesota.
Before transitioning new public site, we are trying to figure out how to put a logo image into RSS feeds.
We use our server to makes xml codes to create RSS feeds for podcasts.
We successfully put a logo image for a collection in a RSS feed, but putting a logo image for a single item did not work.
Below is the part of the xml code for the logo image for a single item, which is created by our server. I deleted other parts of xml code for your convenience.
<item>
<title>Plagiarism</title>
<itunes:image href="http://picture.funnycorner.net/funny-pictures/6041/dolphin-vs-cow-swimmin g-contast.jpg" />

We tried both <itunes:image href="http://picture.funnycorner.net/funny-pictures/6041/dolphin-vs-cow-swimmin g-contast.jpg" /> or <image>http://picture.funnycorner.net/funny-pictures/6041/dolphin-vs-cow-swimming-conta st.jpg</image>.
Both did not work.
Can anyone help?
Thank you for your help in advance!!

Haven't created too many podcasts, but in this one
http://itunes.apple.com/us/podcast/connecticut-college-sculpture/id372414245
or
itpc://video.conncoll.edu/d/sculptures/index.xml
before we included the audio files, we added the images in iTunes.
Select the file, then go to File>Get Info, here you can add metadata, and in Artwork add an image.
Then upload this file to your server. Works for audio files anyways.
You don't see the image in the web podcast, but you do in iTunes after you download each item, in "Show item artwork" in lower left. Click on the image and it zooms out.

Display of icons in the items of dropdownListBox for a single item

Dear BSP Gurus,
Do you know if it is possible to display icons in the items of dropdownListBox for every single item?
To assign and display icon to buttons I do:
    lv_image->id = 'UserSelectionCancel2'.
    lv_image->src = '/sap/public/bc/icons/s_B_OKYE.gif'.
    lv_image->tooltip = ''.
    clear lv_image_string.
    lv_image_string = lv_image->IF_BSP_BEE~RENDER_TO_STRING( page_context ).
              %>
              <xhtmlb:toolbarButton id      = "<%= ywfx1_b_bcontinueWF %>"
                                    design = "STANDARD"
                                    text    = "<%= lv_image_string %> <%= otr(YWF11/ContWF) %>"
But I could not managed to do it for the " <htmlb:dropdownListBox ...".
We have application developed in ABAP WebDynpro and there it is possible, so I want to do exactly the same with BSP.
Any idea?
Thanks in advance,
Valentin

Hallo Alexandre,
But what if I use table for defining the items?
Like:
htmlb:dropdownListBox id = "DropDownCommands"
                  table             = "<%= application->mt_commands %>"
                  nameOfKeyColumn   = "VAL_COMMAND".."
Where "application->mt_commands" is table of strings?
Would it be some how possible?
Regards,
Valentin

Multiple Units of Measurements for a single item

Hi all,
How do I maintain multiple units of measurements for a single Item/ I have a scenario where purchase orders are being made for sand in Metric Tons, Tons, Kgs and Cubit Feets. Each measurement is being used at each construction site of the company but the item is single sand. One more problem is here with the material reconciliation of stock since it is maintained in different units of measurement and conversion from unit to other is problematic.
Thanks

ANN: Learn how to invalidate cache and handle exceptions

http://otn.oracle.com/sample_code/tech/java/codesnippet/webcache/index.html
These set of New OracleAS Web Cache How-to's illustrates how to invalidate cached content using esi:invalidate and PL/SQL invalidation tags. Also, learn how to esi exceptions using esi:try, esi:accept, and esi:except tags.
Cheers,

You may use any of the two ways:
1. Use the interface. Go to Navigator, and go to that particular page where that portlet is, and then edit it. Go to Properties/Cache. See at the very bottom of the page for how to clear cache for that page.
2. See details of the api function for cache invalidation.

How to disable iMessage for a single contact?

Hello apple communites, I have a simple and hopefully simple to answer question..
I am curious as to how to disable iMessaging for a single contact. My sister when she got her phone number originally had an iPhone, she has since gotten an android and kept the same phone number. However I am running into issues with text messages to her, my phone still thinks she has an iPhone and continues to send every text as an iMessage, resulting in a failed message. I can easily hit the "send again as a text message" option and the message/picture sends as normal. I however find this a bit fustrating, and have tried everything I can think of to attempt to disable this. However all the online tutorials I can find regarding disabling iMessage turns the feature off completly, I don't wish to do that.
I have attempted to completely delete, (including all existing all texts and call history), and then re-add the contact, but that does not work either, my iPhone still attempts to send messages to my sister as an iMessge. Any help, if any, would be appreciated. Thanks in advance.

Your sister needs to disable iMessage on her iPhone if the iPhone is still available if she hasn't already done so.
If she has, does she have iMessage enabled with the same Apple ID on another iOS device or on a Mac as was used to activate iMessage on her iPhone?

How to store lead-time and price per MPN for a single Item

We are probably one of the only CEM's that use Oracle Applications in a one-to-one MPN-IPN (Oracle Item Part Number) relationship. We do not currently store multiple Manufacturers under a single Item. Rather, we use the Customer Item Cross Reference to rank the customer's AML, with each IPN tied to a single MPN.
We are looking at moving into a one-to-many "world" in Oracle but are not sure how we can handle different pricing, lead-time, preference, status (prototype, production, obsolete, do not use), etc. for each Manufacturer's Part Number under a single Item. How are other CM's handling this???

Hi Greg,
Unfortunately, DIAdem Datafinder doesn't really support much in the way
of Date/Time search outside of the File Level Creation Date property.
In order to make the creation time of the Channels searchable you would
want to create some custom properties (or use the existing RegisterInt1
- RegisterInt6) to define your own searchable properties.
For example, since you know that you have one TDM file per day, you can
start your search by find the desired day on the File Property Level,
searching the "Creation Date" property. When you store your TDM
properties, you could store the hour creation as an integer (and
thereby searchable) in one of the RegisterInt properties of the
channel, or create your own custom "Hour" channel. You could similarly
save the minute and second property in their own custom properties.
Then, since you're saving integer values, you can then search those
values to determine the time that the channel was created.
I realize that this isn't ideal or elegant, as in total it requires 4
searches (date, hour, minute, second). But that is the most
straightforward way of searching your channels by creation date/time.
Hope this helps Greg, let me know if you have any other questions.

How do I create a Launchpad folder for a single item?

Some items that came with a few apps have their own folder in Launchpad - "AppName (Other)".
Is there a way to create a folder in Launchpad with a single item?
I tried dragging one item to another and got a folder but as soon as I removed one of the items, the folder disappeared too.
Thanks in advance.
Best regards,
Barry
<Edited by Host>

Hi Shootist007,
Thanks for your response.
Trouble is, the app is already inside a folder. It came with another app and both are in their own folder, within the Applications folder.
At your suggestion, I even tried placing it within its own folder, within the app's folder, within the Applications folder. Still seeing two separate icons in Launchpad with no folder.
Both show up in Launchpad as separate things. What I'd like to do is have that secondary app in a Launchpad folder.

Thank you but those aren't email addresses in my signature - they're URLs. No fear of bots.

Programatically validate/invalidate cache for specific query

Hi,
I am looking to programatically invalidate and re-instantiate the cache for a specific query.
I know how to perform this manually via RSRT, RSRT1/2....etc. What I am looking for is a way to schedule this and programatically control caching on specific query.
Any help would be wonderful!!
Thanks!

hi Dong Suk Choi ,
the technical information which u have furnished clearly says that the settings
that u have made does not enable the query to use cache.
u can enhance cache by customizing the inforovider or in the transaction rsrt
even if the concerned query does not have required settings u can make them in rsrt tcode.
goto rsrt set the read mode and cache mode as u wish, however default settings would give optimum performance.
and run the query.
in the rsrt screen a push button execute + debug enter that and unmark the check box do not use cache.
hope this helps.
reward points if helpful.
bye.
under properties tab u can give the query settingMessage was edited by:

How to disable caching for pcui applications

Somehow the PCUI applications are cached and when we go to some opportunity and come back to the previous one,
we can still see the changed data which is not actually saved to the Box but if we refresh the page it will go off.
If we click on save, and if it has some error ,it wont save the opportunity but the changed data remains in the page something like Work protect in Portal.Couldnt find any options in portal and disabling cache for Iview didnt help.How can we disable the PCUI or Sever cache so that the unsaved data goes off..
George

Hello George,
This can be done in two ways, one you can use transaction CRM_BSP_STATE_
ERASE and delete all the previous states.
Otherwise please append crm_bsp_restore=FALSE in the URL. This is
explained in SAP Cookbook. Please have a look at the same. Kindly let
me know for more information on the same.
This issue happens
because of state manager which saves the state for individual
application and individual user . This can be switched off by adding
a URL parameter "CRM_BSP_RESTORE=FALSE" in the query string.
Kindly please reffer the cook book for further detail.
Can you please try this & check if this helps.
Thanks & Regards,
Bhavya

How to Disable cache for an especific Site??

How i can disable in the CE 507 the Cache for one Web Site???

The reply at the link says to configure a rule for "no-cache". This will not prevent the CE from making the request, it only tells the CE to not Cache it.
Reading the question, I am not sure of exactly what the request is, but if the goal is to have the client go directly to the server, there are multiple ways to do this.
If you want the client to make the connection to the site, you can you a redirect list on the WCCP router
In the following example, traffic to 172.18.124.193 will not be redirected to the CE, but will go directly to the server.
router# configure terminal
router(config)# ip wccp web-cache redirect-list 120
router(config)# access-list 120 deny ip any host 172.18.124.193
router(config)# access-list 120 permit ip any any
Or, you can create a static bypass entry on the CE using the bypass command. Bypass, like the router redirect list, requires the use of WCCP.
