I am trying to run 2 exe in Parallel using Parallel.Invoke()
Both the exe is trying to access the same Database (but different tables). Also, the exe's will run in two different servers. I am using WMI with C# to start the batch file (which will invoke the other exe file) in the remote server.
Parallel.Invoke(() =>
{
RunInParallel();
},
() =>
{
InvokeModule("EmiCalculator.exe");
}
);
void RunInParallel()
{
var connoptions = new ConnectionOptions();
var managementScope = new ManagementScope
(String.Format(@"\\{0}\ROOT\CIMV2", REMOTE_COMPUTER), connoptions);
var wmiProc = new ManagementClass(managementScope, new ManagementPath("Win32_Process"), new ObjectGetOptions());
string commandLineInput = @"\\win-server1\D$\Data\Run.bat";
var processToRun = new[] { commandLineInput };
wmiProc.InvokeMethod("Create", processToRun);
}
Run.bat is calling SalaryCalculator.exe
Both the exe are having a configuration file with ConnectionString as below.
<add name="CONN" connectionString="Data Source=SERVER1-LAB1;Initial Catalog=Loan;Integrated Security=True"/>
When running, the exe in remote machine is getting crashed and throwing below exception :
Application: SalaryCalculator.exe
Framework Version: v4.0.30319
Description: The process was terminated due to an unhandled exception.
Exception Info: System.AggregateException
Stack:
at System.Threading.Tasks.Task.WaitAll(System.Threading.Tasks.Task[], Int32, System.Threading.CancellationToken)
at System.Threading.Tasks.Task.WaitAll(System.Threading.Tasks.Task[], Int32)
at System.Threading.Tasks.Task.WaitAll(System.Threading.Tasks.Task[])
NOTE: If I run the batch file after connecting to remote machine, it is working perfectly. It is only throwing error when using with Parallel.Invoke()
How can I proceed here ? Any help is appreciated.
I was able to make this work. The issue was connection string as Integrated Secuity was mentioned. I just changed the connectionstring to use SQL server authentication
instead of Windows authentication. And it worked fine.
< add name="CONN" connectionString="Data Source=SERVER1-LAB1;Initial Catalog=Loan;User Id=sa;Password=xxxx12345678" />
