I am trying to setup a test environment for Orleans that uses SQL Server for liveness. This is my server config file:
<?xml version="1.0" encoding="utf-8" ?>
<OrleansConfiguration xmlns="urn:orleans">
<Globals>
<Liveness LivenessType="SqlServer" DeploymentId="42783519-d64e-44c9-9c29-111111111133" DataConnectionString="Data Source=.\\SQLEXPRESS;Initial Catalog=Orleans;Integrated Security=True;" />
<!--<SeedNode Address="localhost" Port="11111" />-->
</Globals>
<Defaults>
<Networking Address="localhost" Port="11111" />
<ProxyingGateway Address="localhost" Port="30000" />
<Tracing DefaultTraceLevel="Info" TraceToConsole="true" TraceToFile="{0}-{1}.log">
<TraceLevelOverride LogPrefix="Application" TraceLevel="Info" />
</Tracing>
<Statistics MetricsTableWriteInterval="30s" PerfCounterWriteInterval="30s" LogWriteInterval="300s" WriteLogStatisticsToTable="true" />
</Defaults>
<Override Node="Primary">
<Networking Address="localhost" Port="11111" />
<ProxyingGateway Address="localhost" Port="30000" />
</Override>
</OrleansConfiguration>
When I use this config I get this error when running:
MembershipTableGrain cannot run without Seed node - please check your silo configuration file and make sure it specifies a SeedNode element. Alternatively, you may want to use AzureTable for LivenessType. Parameter name: grain = MembershipTableGrain Exception = System.ArgumentException: MembershipTableGrain cannot run without Seed node - please check your silo configuration file and make sure it specifies a SeedNode element. Alternatively, you may want to use AzureTable for LivenessType.
and further up, the logs say that the Liveness is MembershipTableGrain (which is the default and requires a SeeNode). What am I missing here?
My silo config for SQLServer membership looks like this
<?xml version="1.0" encoding="utf-8"?>
<OrleansConfiguration xmlns="urn:orleans">
<Globals>
<SystemStore SystemStoreType="SqlServer" DeploymentId="YYYYY" DataConnectionString="Server=THESERVER;Database=Orleans;User ID=USER;password=PASSWORD;"/>
</Globals>
<Defaults>
<Networking Address="" Port="11111"/>
<ProxyingGateway Address="" Port="30000"/>
</Defaults>
</OrleansConfiguration>
No need to specify the liveness type. It figures it out by looking at the SystemStoreType.
The client config does need the gateway specified
<ClientConfiguration xmlns="urn:orleans">
<SystemStore SystemStoreType ="SqlServer"
DeploymentId="YYY"
DataConnectionString="Server=THESERVER;Database=Orleans;User ID=USER;password=PASSWORD;" />
<GatewayProvider ProviderType="SqlServer"/>
</ClientConfiguration>
您还可以使用可编程API进行配置,而不是使用XML。
I found the problem. That is not how to change the Liveness type. It should be like this:
<SystemStore SystemStoreType="SqlServer" DeploymentId="42783519-d64e-44c9-9c29-111111111133" DataConnectionString="Data Source=.\SQLEXPRESS;Initial Catalog=Orleans;Integrated Security=True;" />
<Liveness LivenessType="SqlServer" />
Also, you must make sure to ref "Microsoft.Orleans.OrleansSqlUtils" NuGet package and run this SQL Create Script
