• Integrate Hibernate L2 cache with consistency in the composite key of reference

  Hi all:
  I have a problem when I activate the Hibernate l2 cache integrated with consistency. When the entity class using this string or unique integer primary key, the L2 cache has worked well. But when I use the entity with composite key class, I had the problem.
  I wrote a script to test junit to test the session.get method, when I run the test cases for the first time, the miss of the entity to load the object from the cache, Hibernate will trigger a DB query so it box as an object, then put it in the cache. But when I run the test case, again, I found the Hibernate trigger a query once again, which was strange... (it should not have happened, I should got the object from the cache), then, I used the console cache coherence to list the data in the cache and finding himself under the information:
  ###########################################
  (Hi) map: list
  model. SiteUserInfo #model. SiteUserID@323819 = Item {version = null, freshTimestamp = 1333943690484
  model. SiteUserInfo #model. SiteUserID@323819 = Item {version = null, freshTimestamp = 1333943600419
  ###########################################
  There are two keys with the same value cached... (I put already implemented method hashcode and equals to SiteUserID object). someone there has the same problem? Or L2 Hibernate with composite key can integrate with consistency?
  
  Rip off code SiteUserID
  #####################################
  @Override
  public boolean equals (Object obj) {}
  If (obj == this) {}
  Returns true;
  }
  If (!) () obj instanceof SiteUserID)) {}
  Returns false;
  }
  SiteUserID id = (SiteUserID) obj;
  return new EqualsBuilder () .append (sid, id.getSid ()) .append (name, id.getName ()) .isEquals ();
  }
  
  @Override
  public int hashCode() {}
  return new HashCodeBuilder () .append (sid) .append (name) .toHashCode ();
  }

  Hi John,.

  I think there may be another problem.

  Please reference:
  http://blackbeanbag.NET/WP/2010/06/06/coherence-key-HOWTO/
  For entry cache, partitioned cache is placed in backup card in binary form.
  The main objects of the same data must always be serialized in binary form even.

  Unfortunately, use Hibernate CacheKey is as key cache L2.
  And CacheKey is somewhat complex, some related attributes use TreeMap as their type.
  "Java gives no guarantee on the order in a hash table and serialization is dependent on the command."
  (reference http://stackoverflow.com/questions/9337126/how-can-oracle-coherence-get-fail-with-retrieved-key-object)

  So... you may need to modify the source code of some Hibernate, ex: replace the FastHashMap in TreeMap...
  I tried, it looks like work. I'll send you have modified source codes.

• Do not use SOA components custom cache config xml

  I created a Java class to interact with consistency. The class is called using the SISM BPEL. Created a custom config cache file, jared it and added the jar in the classpath library. The composite, has deployed the java class is within a SOA project. After you run the composite, the class is called but joined 'SOADistributedCache' defined in 'fabric-runtime.jar!/soa-coherence-cache-config.xml' instead of joining the 'DistributedCache' defined inside my coherence_config.xml. The soa-coherence-cache-config is configuration by default from cache SOA folder as each join of SCA components. The pot is in server classpath and it overrides the property of my "tangosol.coherence.cacheconfig" system which I'll put in my class.
  Here's my class
  public class CoherenceReader {}
  
  
  public String readFromCache (String key) {}
  
  System.out.println ("before calling cache");
  Dim retVal = (String) cache.get (key);
  System.out.println ("value:" + retVal);
  Return retVal;
  }
  static cache of NamedCache = null;
  
  public static
  {
  System.setProperty ("tangosol.coherence.cacheconfig", "coherence_config.xml");
  System.setProperty ("tangosol.coherence.localport", "8088");
  System.setProperty ("tangosol.coherence.wka", "localhost");
  System.setProperty ("tangosol.coherence.wka.port", "8088");
  Thread thread = Thread.currentThread ();
  ClassLoader = thread.getContextClassLoader () loderPrev;
  try {}
  thread.setContextClassLoader (NamedCache.class.getClassLoader ());
  CacheFactory.ensureCluster ();
  System.out.println ("before call getCache");
  cache = CacheFactory.getCache ("employeecache");
  System.out.println ("cache:" + hide);
  }
  {Finally
  Thread.currentThread () .setContextClassLoader (loderPrev);
  }
  
  }
  }
  
  The result is:
  < 29 Aug 2011 18:54:35 IST > < WARNING > < coherence > < BEA-000000 > < 2011 - 08 - 29 18:54:35.269/806.656 Oracle coherence GE 3.6.0.4 < WARNING > (thread = Cluster, Member = n/a): this member is configured with a compatible but different WKA list then the senior member (Id = 1, Timestamp = 2011-08-29 17:10:55.356, address = 172.18.21.94:8088, MachineId = 43870, Location = site: India.TCS.com machine: 01hw299069, process:2508, role = CoherenceServer).

  cache: SafeNamedCache: ViewMap {Name = employeecache, ClassLoader=sun.misc.Launcher$AppClassLoader@1a16869, ServiceName = SOADistributedCache}
  
  Although coherence_config.xml is in the classpath of the project is not taken/overridden by the fabric-runtime.jar!/soa-coherence-cache-config.xml.
  Simply, you can test this by adding a class inside the SOA project and try to access the cache of it.
  Any help on the use of custom for the SOA components cache configuration?

  Hello

  There are 2 files that you will need to develop/specify for the use of the class from BPEL:

  1 tangosol-coherence - override.xml: this file defines the cluster and it should be created separately for each consistency group. Remember, you must have a different cluster created consistency that is used by the components of SOA deployments and discovery. This file will include all your names of WKA and cluster and so on. You can override all the elements specified in the tangosol - coherence.xml in this file. The file can be loaded using the tangosol-coherence-override system property.

  2 coherence-cache - config.xml: this file is used to specify how data is managed within the cluster? Yet once again, this file must be used to manage the cluster which is called using your BPEL code.

  I am sure that you do not specify the tangosol-coherence - override.xml which makes your BPEL class joining the cluster used by SOA to manage components.

  I hope this helps!

  See you soon,.

  Thanks in advance

  The classpath is not the same as the path. It is similar, but a classpath is a set of directories or jar Java files use to search for resources and executable code.

  Assuming you are using the sample file of Start-cache - server.cmd which is supplied with the .net examples to start your server you can put the file tangosol-coherence - override.xml in the C:\Program Files\Oracle\Coherence pour.NET\examples\ContactCache.Java\config directory because it's on the class path when using this script.

• Problems with ImageAssist on the machines using SSDS m2 (NOT is)

  Hello guys,.

  first of all, I must admit, I am facing ImageAssist the first time, so maybe I m ask stupid or boring. I tried the search within this Forum, but didn t get results...

  Okay, so here´s I want to do... our new generation of material (E7270, E5570, OptiPlex7040 far, precision 7710) must be distributed to our subsidiaries around the world. Sometimes they must implement a customer, so I want to create a Sysprep Image BASE + APPS, which I can send to these guys here.

  Here´s so what I've done (problem follows when restoring my Image)

  for example allows to take the E5570, 8 GB of RAM, 256 SED m.2SSD. I installed Win7x64 Enterprise with a Microsoft ISO in a virtual machine using VMWare Workstation 11. My VM config: 4 GB of RAM, 60 GB HD, network in bridged Mode, turn off sound and VM printer and here my first question:

  Inside VM:BIOS or EFI Mode and drive hard ACHI or SATA Raid or SCSI mode? OK, I m prepared and tried all the...

  so after installing win7 and .net 4.5.2 (VMWare Tools also, for the use of slides &) and 2 Reg settings with regard to our environment (MaxTokenSize = 65535 and EnableLUA = 0) I created my BASE Image/Snapshot.

  After you add a few packages of software, I created my BASE + APPS (always with VMWare Tools).

  Next step, uninstall VMWare Tools... restart, after this judgment. now boot into DELL's PE and I created our MaintenanceImage to a network drive. So far all is working well, so I used the installation without assistance-creator tool and define our values (name & Company, selectable language, workgroup, computer name must be completed by the regional IT guy, and I checked to copy the profile to the default user profile... that s he)

  Validation tool crossed without moaning, capturing also...

  I sliced two of the Image (about 10 GB) to some 2 GB and copied on our USB key for testing purposes...

  Stick plugged USBPort E5570, restored, added DELL drivers CAB files and after restoration, the E5570 started Win7x64 for the first time... everything worked fine, etcpp... devices to about 90 percent of the first boot, I get the message: "Windows cannot configure one or more system components. TI install Windows, reboot, and re-install Windows.

  Hope someone could snap this suspicion to my face :D

  I also tried a BIOS/MBR Installation with the 7710 of precision using a standard 2.5 "SSD... I didn t get an error or a problem with this one... restroing & syspreping went well

  Waiting for lots of helpful tips to fix this :)))

• Set the size of the cache does not work (to the great usefulness of RAM)

  Hello
  I posted this question in another forum, but they told me it would be better to aks that here:
  I m read in a csv table and put in a primary database (DB_QUEUE)
  and several secondary databases (DB_BTREE). I m using the Berkeley DB 4.7
  for with C++. For the primary database, I let the standart for the secondary cache size
  databases that I want to use 16 MB:
  
  unsigned long cache_byte = (1024 * 1024 * 16);
  s [a]-> set_cachesize(0,cache_byte,1)
  
  dry [*] are the secondary databases
  and the size of the cache is set before you open databases.
  The problem is when I run the program it allocates more memory.
  but it should just use a little bit more than once 16 MB.
  Can someone help me?

  You can open all databases in a unique environment, with just a cache? Happens usually better, because Berkeley DB can share the cache based on access patterns.

  That said, an increase in size of the memory can be caused by a leak of any where in the application - it may have nothing to do with the cache of Berkeley DB. Have all of the tools that could help track where the memory is allocated? If you're on Linux, valgrind (http://valgrind.org) is great for this sort of thing.

  Kind regards

  My junk mail is to get term with mail that is sent using my email addresses. How can I stop this?

  I can't block emails from myself, I sometimes need to send things, so I got them at a later date.

  I know that I can view the source of the message, but I just want to stop this garbage that runs through for me.

  Can anyone help?

  There is not really a way to do it.  Just like you cannot block spam from your mailbox home - anyone can send you mail and anyone can use a false address 'return' that makes it look like it came from you.

  In fact, it is incredibly easy (only 10 letters typed) to send an e-mail that looks like it comes President @ whitehouse.gov.  That's how spammers do, because there is no check on email (I wish the people who invented the email 40 years ago had thought of that), but it is not just.
