How to batch remove the cache data
I used the Coherence for .NET, and I want to remove some keys from cache. I only found a method Remove(string key) in the Tangosol.Net.INamedCache interface, it can remove only one key each time, it is very slowly.
My cache client and server in different computer.
Does it have a method that can batch remove keys from the cache?

You can remove collections of objects with an EntryProcessor and cache.invoke(). The built-in processor ConditionalRemove() with Always/Present filters should do the trick.
In terms of performance however, note that cache delete operations are always synchronous (even with write-behind) - so removing large sets of objects will be a bottleneck if you have an attached cachestore.

How do I remove the photo dates other than with Sport Removal?
How can I remove the photo dates that appear in yellow from a photo other than using the Spot Removal tool which has not worked?
While I agree that more detail is necessary from the original poster ... maybe even a screen capture
I don't know if this is what the original poster means, but when I have tried to use the Lightroom 5 Enhanced Spot Removal Tool for this purpose, I could never obtain a solution that seemed to remove the offending object and fill in the desired area with a relatively continuous and natural looking result. It always seemed clear to me, when I tried to do this, that the result always had un-natural looking discontinuities in the end result caused by my application of the Enhanced Sport Removal Tool.
And so, in my case, to eliminate the dates from the bottom of my photos, I wound up using different software ... in my case Photoshop Elements, which produced a more satisfactory result.
On the left is the version of the photo created by Photoshop Elements, the date is missing (and at the bottom right, a lamp to illuminate the sign is also missing); while on the right is the image with no attempt to remove the date and lamp. My attempts to reproduce the removal of this date via Lightroom were unsuccessful, the grass never looked natural, the grass always had discontinuities which made the result unsatisfactory, and I did not save the Lightroom attempts to remove the date and lamp. (And if you look carefully on the left, you can see places where the shadows abrupty have disappeared, an artifact of the process, however I still deemed the photo on the left to be successful at the removal of these items, as I don't usually focus on the shadows) -
How can I remove the "Show Data in Single Pane" button from ui:table?
All I have is paginate selected in table properties.
Hi,
Thank you for explaining it so clearly. After enabling the pagination, go to the properties sheet for the table. Under the Appearance section there is a property called paginateButton. Uncheck this property and you will have pagination enabled but not the Show data in a single pane button.
Cheers

how do you remove back up data from the memory storage? my storage data states that i have over 80gb of data used for back ups and i dont know why as i use a external hard drive as a time machine .now my 250gb flash storage is nearly full.. HELP!
When Time Machine backs up a portable Mac, some of the free space will be used to make local snapshots, which are backup copies of recently deleted files. The space occupied by local snapshots is reported as available by the Finder, and should be considered as such. In the Storage display of System Information, local snapshots are shown as Backups. The snapshots are automatically deleted when they expire or when free space falls below a certain level. You ordinarily don't need to, and should not, delete local snapshots yourself. If you followed bad advice to disable local snapshots by running a shell command, you may have ended up with a lot of data in the Other category. Ask for instructions in that case.
See this support article for some simple ways to free up storage space. -

HT5527 So how do I remove the storage amount? What pulls the most data?
So how do I remove the storage amount? What pulls the most data?
I assume this refers to icloud and not the storage on the device.
You'd have to go into the various apps on your device that store data on iCloud and begin trimming files. For example, Contacts and emails that are stored on icloud, must be deleted using the Contacts and Mail apps. Be aware that deleting data from icloud will also remove if from your device.
Backups:
Go to Settings>iCloud>Storage & Backups>Manage Storage; there, tap the device you need info on and the resulting screen lists Backup Options with which apps store data on iCloud. Turn off camera roll and any other apps that might have a lot of data. Then delete the backup. That will free up space. Photos should be regularly synced to a computer (like you store photos from a digital camera) using either USB via iTunes (on a mac use iPhoto or Aperture to move them to an album) or using photo stream. Go to Settings>iCloud and turn that feature on.
Emails:
Regarding emails, on the computer, move emails from mailboxes in icloud to those on the device. That can also save a lot of space.

How to remove the caching in the jspx page?
I have few links in a jsp page through which i can navigate to jspx pages. In one of the jspx pages there are few drop downs of whose options will be populated from database. when I select a value from the drop down (values are prepopulated in the drop down), then go to the jsp page and visit the jspx again through the link, (without closing the browser) the value which i selected previously is selected as a default value. Why this is happening? Is there anything to be set to remove the caching?
Thanks in advance
UdayI have an application which uses JSP - only welcome page, ADF Faces, Spring, Hibernate technologies. The IDE I am using is NetBeans 5.5 bundled with Tomcat & JBoss.
The welcome page (index.jsp) consists of normal html anchors - hyperlinks (2 Numbers) which each hyperlink would navigate the user to 2 individual jspx pages.

hello, we need to remove the dirty data from MDS, but we found we can only do this from MDS web, and we need to do this by store procedure to make this process automatically. is there any easy method to remove the data from MDS automatically? thank.
WarrenHi Warren,
Assuming the dirty data is easily identifiable, all you need to do is use the staging process with import type of 5 (de-activate - i.e., soft delete) or import type of 6 (hard delete).
Could give more details if I knew the version of MDS you are running (SQL 2008R2 or SQL 2012).
Kind regards,

How to Remove “Other” Data from iPhone, iPad and iPod Touch
http://www.igeeksblog.com/how-to-remove-other-data-from-iphone/
With an iOS device, the “Other” space in iTunes is used to store things like documents, settings, caches, and a few other important items. If you sync lots of documents to apps like GoodReader, DropCopy, or anything else that reads external files, your storage use can skyrocket. With iOS 5/6/7, you can see exactly which applications are taking up the most space. Just head to Settings > General > Usage, and tap the button labeled Show All Apps. The storage section will show you the app and how much storage space it is taking up. Tap on the app name to get a description of the additional storage space being used by the app’s documents and data. You can remove the storage-hogging application and all of its data directly from this screen, or manually remove the data by opening the app. Some applications, especially those designed by Apple, will allow you to remove stored data by swiping from left to right on the item to reveal a Delete button.

MudassarHello Mudassar,
In SQL Server / T-SQL we don't have a native JSON support, so you would have to implement a solution on your own = parsing the string and remove the "Key" + it's value.

How do you remove the borders from a table item
In OAF I have a set of data stored in a table that I must display. However, I must make it look like it is not in a table. I can't use a tablelayout because it is a set of records and records are constantly being added. How do I remove the borders and the pagination from the table?
I think you can't do anything about this.
Change you design as per Browser Look and Feel standards.

I have a new MacBook Pro and I followed these instructions, downlonading and installing the new Flash plugin. But when I looked in "/Library/Internet Plugins" there was no folder called "Disabled Plugins".
However, I did see two versions of Flash:
_Flash Player.plugin with old date
Flash Player.plugin with todays date
I deleted _Flash Player.plugin and this fixed the problem.
