How to pass values to SQL server Agent Job which internally calls SSIS

Question

Hi,
I have a requirement where i need to call remotely SSIS package from ASPX. After following MSDN form, I have creaed one SQL server agent job and calling that job from ASPX. I am ablt call SQL server agent job from ASPX. Only issue i am facing is: I need
to pass 2 variables from ASPX to SQL Agent job so that from Job i can map the same to SSIS Package.
I am using system SP (sp_start_job) for calling SQL server agent job as mentioned in MSDN forum.
below is the code , which i am using to call SQL serve agent job.
Code:
SqlConnection
jobConnection;
SqlCommand jobCommand;
SqlParameter jobReturnValue;
SqlParameter jobParameter;
int jobResult;
                jobConnection =
new
SqlConnection("Server=ServerName;Initial
Catalog=msdb;Integrated Security=SSPI;user id=username;Password=password");
                jobCommand =
new
SqlCommand("sp_start_job",
jobConnection);
                jobCommand.CommandType =
CommandType.StoredProcedure;
                jobReturnValue =
new
SqlParameter("@RETURN_VALUE",
SqlDbType.Int);
                jobReturnValue.Direction =
ParameterDirection.ReturnValue;
                jobCommand.Parameters.Add(jobReturnValue);
                jobParameter =
new
SqlParameter("@job_name",
SqlDbType.VarChar);
                jobParameter.Direction =
ParameterDirection.Input;
                jobCommand.Parameters.Add(jobParameter);
                jobParameter.Value =
"ImportCMTData";
                jobConnection.Open();
                jobCommand.ExecuteNonQuery();
                jobResult = (
Int32)jobCommand.Parameters["@RETURN_VALUE"].Value;
                jobConnection.Close();
switch (jobResult)
case 0:
Console.WriteLine("SQL
Server Agent job, RunSISSPackage, started successfully.");
break;
default:
Console.WriteLine("SQL
Server Agent job, RunSISSPackage, failed to start.");
break;
Console.Read();
Thanks

"3-4 concurrent users are calling the SSIS package from ASPX page" this is not a proper design
If the data is being ingested than it is likely that this concurrency will lead to one of the packages die
What you shell do is to just queue the data ingress/processing.
In general, again, packages should not be called from ASP web pages, SSIS is ETL-server side technology there is nothing signalling back to the user whether it was successful. The proper way is to write a REST service or alike.
