Has anyone used Oracle Coherence? It looks very promising at the roadshows. My concern is whether it's a stable and robust enough to implement mission-critical financial solutions. I'd be grateful for any feedback on its performance, robustness and ease of maintenance. ...
In order to get good test coverage, I want to test the WriteExternal and ReadExternal methods of IPortableObject (as described at Creating an IPortableObject Implementation (.NET) ). Here is code similar to what I have in my test method (which I like, and it works). Person person = new Person { Name = "John Doe" }; Person personCopy = ...
I'm using JMX to build a custom tool for monitoring remote Coherence clusters at work. I'm able to connect just fine and query MBeans directly, and I've acquired nearly all the information I need. However, I've run into a snag when trying to query MBeans for specific caches within a cluster, which is where I can find stats about total nu...
Assume that Oracle Coherence is free :) Which one do you prefer? What are the architectural and feature capability differences between Oracle Coherence(Tangosol) and Cassandra? Best Regards ...
Are there any restrictions for using coherence.jar without any license? coherence.jar is open for downloading without any fee. ...
Are there any open source alternatives to oracle coherence? (btw, how much does coherence cost anyways?) ...
Is it possible to use Oracle Coherence to provide distributed caching to an ASP.NET application? We would like to use Coherence to scale out an ASP.NET application which does not have distributed caching. Alternatives would be memcached, etc. However, we are considering Coherence since we already have licensing/expertise in that area. ...
hi, I have the specific scenario for which we want to use Coherence as sitributed cache. Which I am gonna describe here. I have 20+ standalone processes which are going to put the data in cache continuously. the frequency of all of them differs, though thats not a concern. And 2 procesess which will be reading data from those cache....
Weired but I am investigating the Oracle Coherence as a substitue for distribute cache. My primarr problem is that we dont have distribituted cache as such as of now in our app. Thats my major concern. And thats what I want to implement. So, lets say if I take up a machine and start a new (3rd) reading process, it will be able to conne...
All, I just need some pointers in a problem I have. Basically 100 C++ engine instances write to an SQL Server 2005 and it is creating some problems for us. As we don't really need to write the data in the database at that point we are thinking to stop doing it and use either messaging to send the data to a service for furher processin...
I am using a 3rd-party .NET component which requires an XML configuration file. I'm am using this in an ASP.NET application. I get an error when configure the XML with the following dtd: <!DOCTYPE prod-config SYSTEM "cache-config.dtd"> The error is as follows: For security reasons DTD is prohibited in this XML document. To enab...
Looking for advice/pro's/con's on using the memory cache servers for pub/sub esp wrt a high-throughput system ( 1000's of updates/sec ) Coherence seems to have pub/sub as a use-case, not sure about the others Would love to get some real-world input ! ...
I just started working with Oracle's Coherence cache and I noticed this: If I put in a ConcurrentHashMap object in the cache, when I retreive it, I could see that it is converted to a normal HashMap. Anything I can do to avoid this internal conversion? ...
I am using Oracle Coherence cache with Java and am running into an issue. When I put something in the cache (like a map) and get it back using a get call and then modify the object (say, add a value to the map), the modified value is not reflected in the cache. i.e. if I issue a get again, I will get the same old object. This does not oc...
Oracle Coherence states that it is "JCache-compliant". How can I take my code written against JSR-107, specifically the ehcache-jcache jar, and run it against Oracle Coherence? ...
Let's consider two classes: Airport that has a field code. AirportFinder with two methods: loadCache --- reads all the airports from database and puts them into distributed cache with codes as cache keys findByCode --- obtains instance of Airport from cache by its code. loadCache is called during application startup and all subse...
Hello everybody. I have a task to attach Oracle Coherence (it is cache software) in my project. One way of using it is Level2 Hibernate cache. I want to see when hibernate takes results from L2 cache. How can i do that? Both ways will be good: listener of some sort, if possible, or direct access to Cache object. Thanks in advance. ...
I am trying to test that my two coherence clusters are communicating with each other successfully. Everything seems to be running fine besides the Proxys which throw the exception. Failed to instantiate class<My_Class_Name> using org.apache.maven.surefire.booter.IsolatedClassLoader@135ae7e I am trying to run the following command fro...
In POF-serialized .NET objects, I have Class A containing Class B, and Class B has an Attribute X which I want to extract and use in a filter. I can use a SimplePofPath to navigate through the POF stream from A to B and grab X. This works well, except when A.B == null. When A does not have an instance of B where expected, the SimplePof...
