Updates an object in the cache without

• Timer based events on objects in the cache?

  I have commands like:
  

  class Order {
    boolean processed=false;
    boolean stale=false;
  }

  If the order is in the cache for more than 5 minutes without processed being set to true then I would fade the value true. Is there a more elegant way to do it as a timestamp in each object and repeatedly queries with a client application for orders not covered with timestamps more 5 minutes?
  
  Maybe include the timestamp in the Order class but have the ContinuousQuery in the grid to do updates somehow?
  
  Thank you

  Continuous query is not a good candidate for this. It is suitable for maintaining a query result in which an entry is included or excluded from only their own State and does not depend on volatile outside factors such as the weather. This is because the CQC only evaluates an entry to be included at the beginning of the CQC and when the input changes. In general, it will not catch your case to include when it does not change, but the changes of time.

  Depending on the size of your data set and your memory capacity, different approaches can be used.

  Indexing of the flag Rassi and timestamping (together) and periodically sends an input processor filtered by this index for the items that are obsolete but not marked as stale to set the stale flag are probably the fastest, as long as you have enough memory to contain this index.

• the process of updating jnlp is corrupting the cache via hotspot network

  Hi all

  This post is a Java cache problem. We have a jnlp file, responsible for the update of our application (so we cannot put 'offline'). The problem is that some of our users run the application behind a network of wireless access point. In this case, they do not have Internet access, but the java webstart mechanism tries to download the JNLP despite this. In this case, TJS downloads the HTML login page and put it in its cache without any verification. As a result, the next via shortcut access is impossible.

  Is this a known problem and is there a workaround?

  Thanks in advance for your answers

  FYI

  We removed the href of the tag of the jnlp file and it is now ok. The jnlp is never updated, but it's ok for us.

• AS3 - bring an object to the front without using 'addChild '.

  I need to create a menu buttons which expand & overlap on rotation. These menu buttons jump the user to the frame of the scenario. In order to ensure that the buttons do not get covered by the other, I use the excerpt "to object to the Front.

  The code snippet adds selected on the front of the stage as planned, but that is using 'addChild '. This means that the buttons that are renewed are now visible from each image in the timeline. Is there a way to put a button on the front of the stage without replication is done by an extra child?

  See the screenshots for a Visual.

  

  Thank you very much!!!

  Add all buttons to a parent movieclip, which exists only on the image where you want that they exist (and be seen).

  You can then apply the addChild method to that parent.

• JNLP file update does not upgrade the cache of the client (with the shortcut on the desktop)?

  Hello
  
  I have such a problem that the changes made to the JNLP file at the server level are not being updated the JNLP file at the level of the customer if the application is started from a shortcut on the desktop. In my real application I had this experience when adding a jar library to the distributed application on HTTP, but I realized the following example where the source code of a JNLP application (distributed in the local file system) has been changed.
  
  Global:
  In my example, I use the demo tree Dynamics [url http://download.oracle.com/javase/tutorial/deployment/webstart/deploying.html] jar of starting Java-> [url http://download.oracle.com/javase/tutorialJWS/deployment/webstart/ex6/webstart_ComponentArch_DynamicTreeDemo/DynamicTreeDemo.jar] DynamicTreeDemo.jar Web Application deployment. The assessment is done with java 6u26 to Windows XP.
  
  The steps
  < li > 1. Have a JNLP file with jar used (in my example at D:\jnlp-test )
  < li > 2. Start the application from the JNLP file (to create the shortcut on the desktop)
  < li > 3. Edit the JNLP file.
  < Li > - in my example, to update the base code to D:\jnlp-test2. Also copy the JNLP and jar in this directory.
  < li > 4. Run the application from the desktop shortcut
  < li > - 4.1 - at this point, you have to refresh the JNLP file to the cache
  < li > 5. The D:\jnlp-test directory remotely
  
  Results
  (a) after step 4, I think that put JNLP application cache (Control Panel-> Java-> Viewer...) must be updated to contain the new content (new code). BUT my cached JNLP file still contains the old content (in my example = "file:/D:/jnlp-test/" code base)
  
  (b) in step 5, that my candidacy should work properly from the new location of distribution BUT the problem crashes when trying to access the old location with:
  Unable to launch the application
  Error: D:\jnlp-test\DynamicTreeDemo.jar (Maaritettya take ei loydy) +("The path can't be found" in Finnish) +.
  
  My original JNLP (steps 1 and 2) file:

  <?xml version="1.0" encoding="UTF-8"?>
  <jnlp spec="1.6+"
          codebase="file:/D:/jnlp-test/"

  What could be wrong with my JNLP files or y at - it a bug? [url http://www.coderanch.com/t/528570/JNLP-Web-Start/java/Do-jnlp-file-updates-itself#2455103] Updates Coderanch thread jnlp file talks about something similar occurs only when Java Web Start cache path contains white space?

  The original shortcut should always point to the original code base. This is normal. In addition, I don't see how you can expect a JNLP installed (on the client side) to guess it's supposed to now recover the JNLP since a different code base!

• Move all the objects in the model without destroying keyframe positions?

  I built an animation based on a number of position keyframes.  I want to take the entire animation and just back up a bit on the screen so that it is centered better.  However, I don't know how to do this without manually set each keyframe for the move.

  I wish I could nest the whole comp within a clip and then change the position of this element.  Is there a way to do this in AE?

  3 ideas come to mind:

  1. Add a null value and parent all layers to null (if the layers have relatives, and then just parents parents of course). You can delete the null value later and change your keyframes for the new offset.

  2 pre compose all the layers and then move it as a single layer.

  3. If it's a 3D scene, then you can simply move the camera since it controls all the layers.

  I'm new to the Web, what I'm missing here, please?

  So basically if I want to, on the first frame of the main timeline to control outside the navigation of an instance on the stage...

  UH... No. We've already established that you can't control the outside a clip over the first picture, it is on the scene, no matter how much you want. What you can do, is have each clip is hidden during its first image (either by this.gotoAndStop (1), where the frame 1 is empty, this.visible = false), then tap any image after that you can start issuing external goto.

  Or if you really, REALLY can't have this delay of an image so that all was in place, you could go with what Colin has produced and communicate with each clip via external variables. They would even be global. Declare this.clip1Frame = 5; then in the clip have this.gotoAndStop (this.parent.clip1Frame);

  Well, I just did some experiments, and it seems that the real problem here is that the instance of timeline on subitems get immediately initialized. The container itself, clip, however, which means that you can set variables on this subject. Doing so this.myclip.goFrame = 1; in the parent, then this.gotoAndStop (this.goFrame); in the subitem, works.

• How to make the two direct DBS update and write through the same cache?

  Hello
  Sorry for any fault of grammar since English is not my first language.
  Our team is planning to migrate a project centered on the DB to the solution of database consistency. A problem that we face is that a large part of the business logic was implemented in DB stored procedures, which would take the time and effort to rewrite in the entity of consistency model. To for this transition process harmonious and progressive, is there a way to support the two BD update and write through on the same cache? In other words, I want that stored procedures will continue to manage the demand for legacy, after the update, update the web service (update) or (expel/get) the cache; While new logic of business on the same Entity (Cahce), I want to reach write-through. Is it achievable? Thank you!

  Hello

  So what you're really asking is a way to ensure that updates made directly to the DB of your existing system are pushed in cache coherence.

  It is a common problem with a number of possible solutions according to your specific needs.

  If you do not need data in cache, in other words, don't mind if it's a bit outdated, then you can use the expiry and refresh to come so that consistency will expire entries the cache and reading in that the DB to the need to hide.

  If you need accurate data in the cache, it is when it changes on the DB you had to push as soon as possible in the cache, then you need another way. It depends probably the DB that you use and what functionality it provides to allow you to hang change tables.

  The SIG London yesterday there was a presentation on the Oracle Golden Gate to do this kind of thing. I think that it is based on the use of the APP and of course an Oracle DB.

• How to remove an entry in the cache, but does not trigger the erase in the dumps

  Hi guys,.
  
  I meet a really special condition, as the topic, I have a cache to distribute, when putting an object in the cache, Tigger will save method in dumps stored in DB, when remve one entry, will be Tigger method erase to remove it from the DB, and then I need another operation - that can remove just the entry on the cache and will not erase the DB? I checked the method of expulsion, but I think it's for the local cache. How could use on close or distribute cache cache.
  
  
  could someone help me?
  
  Thank you very much.
  
  best,

  Hello

  I tried the entry.expiry (1); in fact for me, he did work and delete the entry without calling the erase method, but he called the store method rather than setting expiration is obviously treated as an update.

  The only way that I managed to make it work so far is to change the process method for the ValueEvictor like that

  @Override
  public Object process(InvocableMap.Entry entry) {
      BinaryEntry binaryEntry = (BinaryEntry) entry;
      ReadWriteBackingMap backingMap = (ReadWriteBackingMap) binaryEntry.getBackingMap();
      Map internal = backingMap.getInternalCache();
      if (internal instanceof LocalCache) {
          ((LocalCache)internal).evict(binaryEntry.getBinaryKey());
      }
      return null;
  }
  

  Is not the most beautiful code and is based on a normal local plan automatically using the storage card internal map reading / writing.

• How to avoid the absences of the Cache?

  Hello
  
  
  Before I explain the problem, it's my current setup.
  
  -Partitioned/distributed cache
  -JPA annotated classes
  -Support card linked to an oracle database
  -Objects are stored in the POF format
  -C++ extend clients
  
  When I ask something that does not exist in the cache, the JPA magic forms a query and assembles the object and which stores in the cache.
  
  However if the query returns no results so consistent returns a lack of cache. Our hierarchy of existing objects may request items that do not exist (this infrastructure is vast and entrenched and changing, it's not an option). This blows near the performance of cache out of the water.
  
  What I want to do is to intercept a lack of cache and store a null object in the cache on this key (null, it will be 4 bytes of length). Client code can interpret the null as a lack of cache object and everything will work as usual - however the null object is stored in the cache and close performance will return.
  
  My problem is, as the JPA annotated done any 'magic', I do not get to intercept if the query returns an empty set. I tried both triggers of card and listeners, but as expected they don't called as no result set is generated.
  
  Does anyone know of a port of entry where I can return an object to consistency in the case of a query that returns an empty set. I also want the option to configure this behavior on a per-cache basis.
  
  Any help gratefully received.
  
  Thank you
  Rich

  Hello

  If you use 3.6 you can do so by writing a subclass of JpaCacheStore that implements BinaryEntryStore or way more genric (that would be for other people who have asked similar questions recently) would be to write an implementation of BinaryEntryStore that wraps another cache store.

  Here's one that I hit until recently...

  package org.gridman.coherence.cachestore;
  
  import com.tangosol.net.BackingMapManagerContext;
  import com.tangosol.net.CacheFactory;
  import com.tangosol.net.DefaultConfigurableCacheFactory;

  import com.tangosol.net.cache.CacheStore;
  import com.tangosol.run.xml.XmlElement;
  import com.tangosol.util.Binary;
  import com.tangosol.util.BinaryEntry;
  
  import java.util.Set;
  
  public class WrapperBinaryCacheStore implements BinaryEntryStore {
  
      private BackingMapManagerContext context;
  
      private CacheStore wrapped;
  
      public WrapperBinaryCacheStore(BackingMapManagerContext context, ClassLoader loader, String cacheName, XmlElement cacheStoreConfig) {
          this.context = context;
          DefaultConfigurableCacheFactory cacheFactory = (DefaultConfigurableCacheFactory) CacheFactory.getConfigurableCacheFactory();
          DefaultConfigurableCacheFactory.CacheInfo info = cacheFactory.findSchemeMapping(cacheName);
          XmlElement xmlConfig = cacheStoreConfig.getSafeElement("class-scheme");
          wrapped = (CacheStore)cacheFactory.instantiateAny(info, xmlConfig, context, loader);
      }
  
      @Override
      public void erase(BinaryEntry binaryEntry) {
          wrapped.erase(binaryEntry.getKey());
      }
  
      @SuppressWarnings({"unchecked"})
      @Override
      public void eraseAll(Set entries) {
          for (BinaryEntry entry : (Set)entries) {
              erase(entry);
          }
      }
  
      @Override
      public void load(BinaryEntry binaryEntry) {
          Object value = wrapped.load(binaryEntry.getKey());
          binaryEntry.updateBinaryValue((Binary) context.getValueToInternalConverter().convert(value));
      }
  
      @SuppressWarnings({"unchecked"})
      @Override
      public void loadAll(Set entries) {
          for (BinaryEntry entry : (Set)entries) {
              load(entry);
          }

      public void store(BinaryEntry binaryEntry) {
          wrapped.store(binaryEntry.getKey(), binaryEntry.getValue());
      }
  
      @SuppressWarnings({"unchecked"})
      @Override
      public void storeAll(Set entries) {
          for (BinaryEntry entry : (Set)entries) {
              store(entry);
          }
      }
  
  }

      true
  
  

  As you can see it the WrapperBinaryCacheStore takes four parameters cpnstructor (configured in the settings-init)
  

• First is the card holder frame
  
• Second is the ClassLoader
  
• Third is the name of cache
  
• Fourth is the XML configuration for the cache store that you want to encapsulate

  If the load method of the wrapped store cache returns null (i.e. nothing in DB corresponds to the key), then instead of returning null, the BinaryEntry is updated with a binary file that represents the null value. Because the corresponding key is now in the cache with a null value, then the cache store is not recalled for the same key.

  Note If you do this, and then later your DB is updated with the values for the keys Traoré were previously null (by something other than consistency) then coherence does not charge them because he is never going to charge for these keys.

  I gave the above code a quick test and it seems to work fine.

  If you are using 3.5 then you can still do it but you must use the coherence incubator common library that has a version of BinaryCacheStore. The code and configuration will be similar but not identical.

• will never be an update where you can erase a background object of an image without clear photo behind the object and have the result as if the object was not always on the picture in the first place.

  I guess this feature without doubt not will be part of Lightroom because of the non-destructive nature publishing. Is that programs like Photoshop are for. But I don't speak for Adobe, because I do not work for them, and I did not all understand what are their plans for the future.

• How to force the cache update swf to the newer version without overwriting all files

  Hi I have a system of e-learning in line with XMLs, SWFs, etc...

  These are cached locally. When I have a new update of the user used to clear their local cache otherwise they would not receive what is ridiculous.

  Now we have a system that replaces everything what we call "Break cache", BUT the problem is I can't clear the cache just one or two file updated.

  Is this possible? I was told it is the html tags that operate in the browser that deals with this, write us, but now I'm totally lost. There must be a solution, it is only common sense.

  Thaks in advance.

  Yes codeBeastAdobe, I mean that I usually do a single XML file that describes the hierarchy of my project. Each article, paragraph, within those, assets etc. On each node, I would have a version, if necessary. The size of the XML file is about ~ 50 k on a large project, or the size of a small image. It is the only ONE without a cache file that I load in requesting it with a seed.

  In this, each piece as you mentioned (food.swf, clothes.swf, sounds, etc.) would be in their appropriate section that looks like my interface what to load. In addition, I would add in a simple attribute where the managed version are elements.

  Very simple example:

  Content / somesection.swf

  Assets/Clothing.swf

  Assets/somevideo. MP4

  Of course, XML is much more detailed with specific attributes of application and structure, but you get the general idea. Only, I have download this app.xml without cache and compare it to the current version of an asset I.

  With the help of a system like this means that you must know which version of one that you have makes it so you will need a system for that as well but this is a whole different debate.

• How to store and update the cache to the 2.3 OHC?

  We have a few dozen workflows (CPO 2.3 process) each triggered by a single event of the tide to start. Each workflow at the outbreak extracts digital data (two or three data double-digit like for example 15, 300) from one end of point plural web service and uses the same in its workflow logic. Data extracted from each workflow is usually specific to this workflow. We want the workflow to locally cached the data thus retrieved. Reason for caching data locally to the POC: the research of web service rate is 100 + searches per second and the web service cannot evolve beyond 100 searches per second. The data thus cached will be local to this workflow.

  QUESTIONS PLEASE:

  1. What is the best way to store the data of recovery? It uses local variables or global variables or other storage mechanisms?

  2. in case the so cached data be retrieved whenever the process (workflow) is restarted?

  3. when the data is changed in the web service, the web service can return fresh data to CPO to refresh the previously cached data. What is the best way to receive these data in order to refresh the cache local to the CPO while the worklfow is running and operating [(i.e.) without disturbing the running of the workflow state]?

  You will appreciate the detailed responses please avoid follow-up questions.

  Thanks in advance,

  Jamal

  If the data are really local to the workflow, use a range of process definition variable.

  But your options are extended definition process variables, variable global or service objectives.  Scope of the definition and global variables are almost the same, varying by what other workflows can see and set data.

• Taskflow Rollback is the origin of the display objects clear their cache

  We use JDeveloper 11.1.2.4 and JHS 11.1.2.4.  Application modules are derived from JhsApplicationModuleImpl.  It seems that the session of preparation is getDBTransaction () .setClearCacheOnRollback (false);

  We have a taskflow for pop up containing a backup and Cancel button more dynamic content region.  The idea is that the backup will call back activity that performs validation.  This will also close the pop-up window.  The Cancel button is similar to the record button, but the return of the activity will end the transaction with a rollback.  This seems to notify all objects in consultation: to deliver a restoration.  This causes each view object clear their cache, and then rerun the query. However, when the cancellation occurs, it causes all active views to be erased and updated.  There is a performance problem because all user data, module, menu and permission of JHS are updated.

  I also tried to use savepoints taskflow and observed the same behavior.

  It seems that the setClearCacheOnRollback may not be glued to or support has changed.

  I can also look at doing something different, but this seems to be a little problem with the extensions of JHS and / or ADF.  My other thing involves a managed bean that can invoke the effective cancellation of the view in question object.

  
  Thank you

  Brad,

  The best way to solve this is to change the scope of control of data isolated for popup workflow group.

  In this way the workflow gets its own am instance and will only restore their own data.
