RE: Re: Ignite.Net Read through approach - error : could not create .Net cachestore

[Alexandr Shapkin]

Sudhir,   Can you share a stacktrace?   It’s difficult to locate the problem without the details. According to source code, the exception is thrown when .NET side is unable to create a CacheStore instance. Since you have configured a factory, please, check that it returns a correct instance and the class is present for required nodes.   From: Mikael Sent: Thursday, November 14, 2019 10:37 AM To: user@ignite.apache.org Subject: Re: Ignite.Net Read through approach - error : could not create .Net cachestore   Hi! The client should not have to pass any cache configuration, once the cache is created in the server, you should just be able to get the cache, I do not see any reason that should not work but I have never used .NET so it is possible there is some hickup there that I am not seeing. You do not have any other Ignite servers running on the same subnet or something ? verify that the client connect to the correct server (sounds silly but I managed to mess up a number of times ;). Is it just that cache ? could you create another cache as simple as possible (no cache store) and see if it will find that one ? It sounds like it cannot create the actual cache store but in that case I would think you would get the exception in the server and not the client, is there any more useful information from the exception ?

This works when used with thin client but when I use it with normal ignite node with ClientMode =true, it is throwing above exception with that message when I call GetCache function call from client node for a key from cache created in server node.   Are there any samples for ReadThrough operation done from normal ignite client node?     Regards, Sudhir On Wednesday, November 13, 2019, Alexandr Shapkin <lexw...@gmail.com> wrote: Sudhir,   What exception are you getting?
