SQLServer Persistence Store Error
Hi,
In my .NET application, I have an underlying SQL Server DB that I am
planning to access using Ignite Persistence feature. I was following the
StoreExample provided in the examples and created the ignite configuration
accordingly.
<property name="cacheConfiguration">
<list>
<bean class="org.apache.ignite.configuration.CacheConfiguration">
<property name="writeThrough" value="true"/>
<property name="readThrough" value="true"/>
<property name="cacheStoreFactory">
<bean
class="org.apache.ignite.platform.dotnet.PlatformDotNetCacheStoreFactory">
<property name="typeName" value="MyIgnite.SQLServerStore,
MyIgnite"/>
</bean>
</property>
</bean>
</list>
</property>
My SQLServerStore which is part of MyIgnite dll is as below. I am using
EntityFramework as ORM to access underlying SQLServer.
class SQLServerStore : CacheStoreAdapter
{
private TestEntities entities;
public SQLServerStore()
{
entities = new TestEntities();
}
/// <summary>
/// Loads all values from underlying persistent storage.
/// This method gets called as a result of <see
cref="ICache{TK,TV}.LoadCache"/> call.
/// </summary>
/// <param name="act">Action that loads a cache entry.</param>
/// <param name="args">Optional arguments.</param>
public override void LoadCache(Action<object, object> act, params
object[] args)
{
var personDetailsList = entities.PersonDetails;
// Iterate over whole underlying store and call act on each
entry to load it into the cache.
foreach (personDetail entry in personDetailsList)
{
act(entry.personD, entry);
}
}
}
Whwn I try to run the above, I am getting the below error.
Apache.Ignite.Core.Common.IgniteException was unhandled
HResult=-2146233088

Oh ok...will try that option. Sure, will send you the zipped copy of my
solution for you to investigate further. Thanks much for your help.

Re: SQLServer Persistence Store Error
Posted by Murthy Kakarlamudi <ks...@gmail.com>.
Hi Pavel...Yes the solution you suggested is working. Thanks so much for
your help.
Regarding my other question, is there a way to query the cache other than
writing a client node? Something similar to IGNITE_H2_DEBUG_CONSOLE on java
side?

Re: SQLServer Persistence Store Error
Posted by Pavel Tupitsyn <pt...@gridgain.com>.
I have tested the attached solution. Everything works fine.
You just have to add BusinessUnit to the BinaryConfiguration:
var cfg = new IgniteConfiguration
{
SpringConfigUrl = @"config\ignite.xml",
JvmOptions = new List<string> {"-Xms512m", "-Xmx1024m"},

Re: SQLServer Persistence Store Error
Posted by Pavel Tupitsyn <pt...@gridgain.com>.
Satya, zip file downloaded fine, I'll investigate it and get to you later.
Regarding [Serializable]: cached objects in Ignite are serialized and sent
over the network.
So your entities should be set up for serialization, one way or another,
see details: https://apacheignite-net.readme.io/docs/serialization
It is possible to serialize auto-generated classes without modifying them,
by providing them in BinaryConfiguration. I'll check attached code and see
if it works.
IGNITE_H2_DEBUG_CONSOLE: just add the following line anywhere before
Ignition.Start: Environment.SetEnvironmentVariable("IGNITE_H2_DEBUG_CONSOLE"
, "true");
Pavel.

Re: SQLServer Persistence Store Error
Posted by Murthy Kakarlamudi <ks...@gmail.com>.
Hi Pavel,
I was playing around with different options and once I specified
[Serializable] annotation at the entity class level, I was able to
successfully insert into cache. With this setting LoadCache() method is
working as well. Not sure if this is the right approach. I will not prefer
this as this needs an update to a auto-generated class and any subsequent
updates might overide the manual settings.
On a separate note, is there a way I can query the cache using sql console.
In java, I can set IGNITE_H2_DEBUG_CONSOLE to query the cache. Wondering if
there is an equivalent on .NET side.
Thanks,
Satya.

Re: SQLServer Persistence Store Error
Posted by Murthy Kakarlamudi <ks...@gmail.com>.
Hi Pavel,
I am not able to send the solution zip in gmail. It is blocking as the
zip file contains executables. Can you please check if you can download the
solution from the below location:
https://drive.google.com/open?id=0B8lM91-_3MwRS3pFU2JwRjJkYVU
Thanks,
Murthy.

Re: SQLServer Persistence Store Error
Posted by Pavel Tupitsyn <pt...@gridgain.com>.
LoadCache arguments are serialized and passed over network. Cache instance
can't be used as a LoadCache argument.
Please try to do a cache put directly in the main method:
using (var ignite = Ignition.Start(cfg))
{
var cache = ignite.GetCache<int, CustomTransactionsDetail>(
null);
cache.Put(1, entities.CustomTransactionsDetails.First());
}
I suspect there is an issue with serializing CustomTransactionsDetail
instances.
Entity Framework POCO proxies can't be serialized by Ignite automatically.
You have to either disable proxies (
https://msdn.microsoft.com/en-us/library/dd456853(v=vs.100).aspx), or
implement IBinarizable with manual serialization.
If you send me your whole solution in a zip file, I'll be able to
investigate further.
Thanks,
Pavel.

Re: SQLServer Persistence Store Error
Posted by Murthy Kakarlamudi <ks...@gmail.com>.
Hi Pavel,
I was trying to do that before and ran into issues passing cache object
to my CacheAdapter implementation which is in a different dll. Can you
please help where I went wrong:
In my main program, I was passing cache in LoadCache method:
using (var ignite = Ignition.Start(cfg))
{
Console.WriteLine(">>> Cache query example started");
var cache = ignite.GetCache<int,
CustomTransactionsDetail>(null);
*cache.LoadCache(null,cache);*
Console.WriteLine(">> Organization Cache Size: " +
cache.GetSize());
Console.ReadLine();
}
In my CacheStoreAdapter implementation, I tried to access Cache as below:
public override void LoadCache(Action<object, object> act, params object[]
args)
{
try {
* ICache cache = (ICache)args[0]; // Throwing an error here.*
var customTxnDetailsList =
entities.CustomTransactionsDetails;
// Iterate over whole underlying store and call act on each
entry to load it into the cache.
foreach (CustomTransactionsDetail entry in
customTxnDetailsList)
{
Console.WriteLine("Adding to cache: {0} {1}",
entry.CustomTransDetailID, entry);
//act(entry.CustomTransDetailID, entry);
}
}catch(Exception e)
{
Console.WriteLine("Exception is {0}", e);
}
}

Re: SQLServer Persistence Store Error
Posted by Pavel Tupitsyn <pt...@gridgain.com>.
Instead of LoadCache, can you try a simple cache put and see what happens?
cache[1] = new CustomTransactionsDetail();
and with entity from EF:
cache[2] = entities.CustomTransactionsDetails.First();
Pavel.

Re: SQLServer Persistence Store Error
Posted by Pavel Tupitsyn <pt...@gridgain.com>.
Satya,
In your code above there is "act(entry.personDetailID, entry);",
but there is no personDetailID member in the CustomTransactionsDetail
class.
Are you sure this is the correct one? Also, it is a partial class - are
there any parts in other files?
Can you attach full source code of your application?
Thanks,
Pavel.

Re: SQLServer Persistence Store Error
Posted by Murthy Kakarlamudi <ks...@gmail.com>.
Below is my entity. I am not doing any serialization currently while
storing in the cache.
namespace MyIgnite
{
using System;
using System.Collections.Generic;
public partial class CustomTransactionsDetail
{
public Nullable<int> TransactionID { get; set; }
public string TypeName { get; set; }
public Nullable<System.DateTime> Expiry { get; set; }
public string Side { get; set; }
public Nullable<System.DateTime> TimeStamp { get; set; }
public Nullable<int> CustomTransHeaderID { get; set; }
public int CustomTransDetailID { get; set; }
}
}
Thanks,
Satya.

Re: SQLServer Persistence Store Error
Posted by Pavel Tupitsyn <pt...@gridgain.com>.
Satya,
Looks like exception comes from your entity member(s) during serialization.
Can you please attach your entity class code?
* Does it have any navigation properties that may cause SQL queries?
* How do you serialize it in Ignite? (Do you implement IBinarizable?)
Thanks,
Pavel.

Re: SQLServer Persistence Store Error
Posted by Murthy Kakarlamudi <ks...@gmail.com>.
Hi Pavel,
Thanks for your response. I stepped through the LoadCache method in
debug mode and noticed that it is failing at the act() method. Below is my
code for LoacCache.
public override void LoadCache(Action<object, object> act, params object[]
args)
{
var personDetailsList = entities.personDetails;
// Iterate over whole underlying store and call act on each
entry to load it into the cache.
foreach (personDetail entry in personDetailsList)
{
Console.WriteLine("Adding to cache: " +
entry.personDetailID);
act(entry.personDetailID, entry);
}
}
I can see the statement: "Adding to cache: " in the node output and the
control hangs at the next line executing the "act" method and then it
throws SQLException Timeout. Not sure why the "act" method is taking so
much time to store the entries in cache.
For testing, I commented out "act" statement and the program completed
looping through all the entries returned by Entity Framework without any
errors.
Thanks,
Satya.

Re: SQLServer Persistence Store Error
Posted by Pavel Tupitsyn <pt...@gridgain.com>.
Hi Satya,
"*Timeout expired. The timeout period elapsed prior to completion of the
operation or the server is not responding.*"
This is an SQL exception. Please make sure that your entity connection
works.
You can set a breakpoint on the first line of LoadCache method, step over
your code and see what happens. Or wrap it in try-catch block.
Meanwhile, looks like cache store error messages are not very informative.
I've added a Jira ticket, we'll fix it shortly:
https://issues.apache.org/jira/browse/IGNITE-2943
Thank you,
Pavel

Hello all,
I was able to resolve the error I posted above. I had to basically add
the relevant EntityFramwork references in the solution that runs my Ignite
