  How about TopLink Essentials?

  You can certainly use EclipseLink as a JPA dumps/Loader consistency.

  The Guide to coherence 3.5 contains information [Configuration consistency with JPA | http://coherence.oracle.com/display/COH35UG/Configuring+Coherence+for+JPA]. The example configuration in the manual is TopLink Essentials, but didn't need to change much for EclipseLink. The main differences are the provider name and the names of the properties. Below, I've edited the persistence.xml example for use with EclipseLink.

  If you use TopLink grid there are [working example | http://www.oracle.com/technology/products/ias/toplink/doc/11110/grid/TopLinkGrid-Examples.zip] available in the [integration guide of | http://www.oracle.com/technology/products/ias/toplink/doc/11110/grid/tlgug002.htm#CHDEEHFB].

• Configuration problem of the mixture of the regions with and without installation of persistence of the disc causing the JSONFormatter to fail

  I have trouble setting my local setup correctly with a mixture of regions with different configuration of persistence of disc.  Is a configuration problem on my end or a bug in GemFire and/or Spring GemFire data?

  The configuration of my work is as follows:

  < gfe: replicated-region id = "replicatedRegion" cache-ref = "gemfireCache" disk-store-ref = "overflowOnlyDiskstore" persistent = "false" >

  < gfe:eviction type = threshold "HEAP_PERCENTAGE" = "90" action = "OVERFLOW_TO_DISK" / >

  < / gfe: replicated-region >

  < gfe:local - region id = "localRegion" cache-ref = "gemfireCache" / >

  
  

  With the above configuration, I can successfully call JSONFormatter.fromJSON (json) and get a reference to a PdxInstance object.  However, when I kinda modify configuration to enable the persistence of drive on one of the regions, the call to JSONFormatter.fromJSON (json) fails.  The change is as follows:

  
  

  < gfe:local - region id = "localRegion" cache-ref = "gemfireCache" persistent = "true" disk-store-ref = "persistOverflowDiskstore"/ >

  Without any additional modification, the following error starts occurring:

  com.gemstone.gemfire.pdx.JSONFormatterException: could not parse JSON document: [Source: java.io.StringReader@5549f0e, line: column 26,: 6]

  at com.gemstone.gemfire.pdx.JSONFormatter.fromJSON(JSONFormatter.java:66)

  ...

  Caused by: com.gemstone.gemfire.pdx.PdxInitializationException: The PDX metadata must be persistent in a limb that has persisted data. See CacheFactory.setPdxPersistent.

  at com.gemstone.gemfire.pdx.internal.PeerTypeRegistration.checkAllowed(PeerTypeRegistration.java:531)

  at com.gemstone.gemfire.pdx.internal.PeerTypeRegistration.verifyConfiguration(PeerTypeRegistration.java:515)

  ...

  Note that it is breaking while I try to get a reference to a PdxInstance, and if the code has not yet arrived at the point where I place a PdxInstance object in a region.

  Thanks for any help in advance.

  Hello

  JSONFormatter PDX uses as is the serialization mechanism from the Gemfire cache. As indicators of error, you must have your persistent PDX meta-data when you use PDX with an area that itself is persistent. Adjust your configuration as follows:

  It will use a default for PDX record store, but you can also use a specific store if you wish.

  When you use PDX, a "PDXType" is created for each class serialized with PDX and this type id is stored with the data in the region. If this region is persistent, then the PDXType, associated with this object must also be kept.

• Eliminating the persistence of the status of component Webcenter Page for a specific Page

  I have a page in Application Webcenter (MDS enabled) which consist of a task flow from the shared library.

  JSFF components: Accordion Panel.

  I am disclosing the accordion and leave the page. (Collapse or Expand) State of the accordion is persisted when you navigate to the page again.

  Question: I want the accordion to restore original state instead of persist.

  Hello Teddy,.

  This is the default behavior of the webcenter Portal / ADF to persist in the State. If you need to set it to the default state you need to programmatically set the total communication of individual showdetailsitem to true.

  If the accordion to taskflow then you can use beforephaselistener to view the activity called a bean managed to set the details element see the declared property when the page is loaded.

  Binary: Disclose by program a ShowDetailItem in a

  panelTabbed - first tab selected when the page is loaded

  You can imagine we are building! : disclose an element of detail see the tab of the Panel by default ADF

  Thank you

• Persistence of the VM?

  Let me preface by saying: I'm an analyst of malware, not a system administrator.  I can ask stupid questions, apparently.

  There... now it's the road.  So, I'm trying to set up a virtual machine that my package analysts allows to download alleged malware and drop it in my sandbox.  For obvious reasons, I want that this VM restore from snapshot during the shutdown.  I know that in VMWare Workstation, there was an option for this, but I can't find any similar option in VSphere.  Can it be done?  If so, how?

  Welcome to the community,

  Yes this can be done with ESXi too. All you need to do is put the virtual disk to "independent - not permanent" (see create a ramdisk in the vSphere Client for more details)

• Persistence of the instance

  Hello
  Can you please if there is a way in the Web Oracle BPM Enterprise Server console so that we will not store instances for specific processes in the Oracle Enterprise BPM engine database.
  
  Thank you
  Abhishek

  There are three techniques if you do not want to store instance information in the database engine that flows point instance work through the process if all activities are automatic activities.

  (1) If you are using Oracle BPM 10 g, set your process for the execution of "Gourmet" (tab in the right project of the ILD process mouse browser-> click on 'Properties'-> click on the 'Advanced' tab-> click 'Activate greedy execution'). This causes the fully automatic process run as a transaction limit and do not write to the database of the engine after each activity ends.

  If you are using Oracle 10g BPM or an earlier version, you have two other options:

  (2) you can call a procedure, individual tasks would not continue in the database of the engine, but the validation of the transaction at the end of the procedure would or
  (3) If you group several automatic activities together in a 'group' (Gordon-> several activities using your mouse-> right click on 'Create a group with the selection' click 'Runtime' and then click on the checkbox "Atomic is".)

  Don't forget to disable the 'events' for these processes. If you have not, the instance information will always be written in the event of the audit trail table.

• using PersistentStore or sqlite to cache feeds the server

  Hello world?

  I'm get the stream from my server at intervals lets say 5 minutes and I want to be able to cache that feeds from the server (electronic data interchange is json), now I am confused it will be wiser to use sqlite to store these data or I use the persistentstore, my confusion is the persistent vector size against the size of the sqlite database and also performance and efficiency in operations reaad and writing Thank you.

  Download 5 MB every 5 minutes seems to be wrong.  But maybe I'm old fashioned.

  If you treat it just like a sequential file, you could just stick it on the SD card yourself, it will be faster, but much less flexible than SQLite.  .

  For a file of this size, I would not put it in the persistent store if it was for all those consumers who might have small curve devices.  But if you target it to the high end of recent phones, then 5 MB is not a concern, and it would be much easier.

• PersistentStore is not persistent between the device restart

  Hello

  I use the PersistentStore to store a hash table with an integer simple mapping custom of POJO. It seems to work between the restarts the application, IE, I can totally my application and restart and persistent data are restored. However, after a reboot of the appliance, such as pulling on the battery, the data are there not more and everything is reset to 0 by default. Same thing happens on the Simulator.

  I certainly call the commit() every time I change the contents of the table of hash and that in a thread safe way. Nothing appears in the journal of the events, or all exceptions...

  It's with OS 4.6.0 and in this case a "BOLD".

  One with ideas or similar issues that I could hurt?

  Thank you.

  Daniel

  Right, I found the problem: all the objects you want to persist must implement the Persistable interface. Too bad there is no word about it in the JavaDoc of PersistentStore and PersistentObject and too unfortunate that PersistentObject.setContent () takes an object as a parameter instead of an instance of a Persistable implementation. That probably has to do with the fact that the implementation allows implicit persistables objects as the Java object representatives for more than native data types Hashtable and vector.

• Order is created for the anonymous user without persistence of profile

  Hi all

  Could you please specify o how to implement below scenario

  Order is created for the anonymous user without persistence of the profile using cookies. So that when the user visits the site next time we can load

  order/cart previous from browser cookies.

  Yes, you can do that, the orders can be persisted without persistence of profile, but persistence of anonymous orders will increase the number of orders in the table quickly and can have an impact on performance, so if you plan to do it this way then make sure that your AbandonOrderScheduler job is running to clean up orders.

• A-team - MAF Persistence Framework - is available for the MAF and it is an approach recommended by Oracle for Application Data Sync?

  Hi OTN community.

  My query is on Oracle team Persistence framework (http://www.ateam-oracle.com/going-mobile-with-adf-implementing-data-caching-and-syncing-for-working-offline/).

  It is available for the MAF and it is an approach recommended by Oracle for the implementation of data synchronization?

  Can anyone please share their experience using this extension.

  We are currently reviewing the best approach for the implementation of data synchronization.

• Questions about PersistentStore/PersistentObject

  Hi all!

  This is my first post and also a newbie on blackberry development.

  Before I start to develop one, I first some ideas on PersistentStorage.

  My questions are the following:

  1. What is the maximum size of the PersistentStore?

  2. what the read/write speed? I ask this question because I need to store data about 200 k.

  . One of my colleagues use before RMS but he can't handle the kind of data that we have to handle.

  Example, it takes 20 seconds to write 50 K with RMS data.

  If it is a byte array, then you don't need to do any conversions to store in RMS.  That said, I see no reason, except compatible with J2ME devices, than you would.  So I recommend you Persistentstore.

  About your second question, I'm not sure that understand how you would sort an array of bytes.

  In addition, these two are the mechanisms of persistence, rather than data management mechanisms.  If RMS or Persistentstore will directly help you with this sort of thing, but given that Persistentstore can be used to store objects, not just bytes, you will probably find it much easier to work with.

  If you plan to do the filtering, searching, sorting etc then you should look at SQLite.

  Is it possible to have the scanners NOR
  show waveforms with persistence as benchtop Agilent and Tektronix
  Oscilloscopes? I understand ZTec modular oscilloscopes have this function. I have
  guess, it can be progemmed using LabVIEW, but is there one out of the way of the plateau of
  do?

  Thank you.

  It is currently not a single property or a function that implements persistence for NOR-SCOPE. Your interest for this feature was placed along R & D for future consideration.

  You're right that you can set this feature in LabVIEW.  I consider using a graph of intensity. The value of x is your time, the value of is the extent of your blood and you browse your waveform, you must create the z values to show the persistence of the wave.  Maj reqisters can be used to track the intensity of the previous iteration.

• Get the error code: 0 x 524 then that he was trying to install Office Live update through automatic updates.

  Microsoft recently released an automatic update for OfficeLive but it will not install on my Dell laptop.

  He tried with persistence, but the same error message each time.

  No one knows what that this error message please?

  I've hidden the facility but the auto-updater will install no subsequent updates until this is fixed (or so he says)...

  In any way, if you can make the light would be great!
