I'm using the SAS Integration Technologies COM components to connect to SAS Server from a C# .NET project. I want to submit statements to a SAS Workspace then load the output dataset from SAS using the OLE DB provider (SAS.IOMProvider). I am able to do this successfully using code like this:
static int Main(string[] args)
{
var keeper = new ObjectKeeper();
var factory = new ObjectFactoryMulti2();
var server = new ServerDef()
{
MachineDNSName = "sas.server.com",
Protocol = Protocols.ProtocolBridge,
Port = 8591,
BridgeSecurityPackage = "Negotiate",
};
var workspace = (IWorkspace)factory.CreateObjectByServer("Workspace1", true, server, null, null);
keeper.AddObject(1, workspace.UniqueIdentifier, workspace);
try
{
using (var conn = new OleDbConnection("Provider=SAS.IOMProvider.1; Data Source=iom-id://" + workspace.UniqueIdentifier))
{
// success
conn.Open();
}
}
catch (Exception ex)
{
System.Console.Error.WriteLine(ex.ToString());
return 1;
}
finally
{
keeper.RemoveObject(workspace);
workspace.Close();
}
return 0;
}
However, when I try using the ObjectPool feature of ObjectFactoryMulti2, the OLE DB connection doesn't work. It always throws "The object could not be found; make sure it was previously added to the object keeper." Here is the code that does not work:
static int Main(string[] args)
{
var keeper = new ObjectKeeper();
var factory = new ObjectFactoryMulti2();
var server = new ServerDef()
{
MachineDNSName = "sas.server.com`",
Protocol = Protocols.ProtocolBridge,
Port = 8591,
BridgeSecurityPackage = "Negotiate",
MaxPerObjectPool = Environment.ProcessorCount,
RunForever = true,
RecycleActivationLimit = 100,
};
var login = new LoginDef();
var pool = factory.ObjectPools.CreatePoolByServer("Pool1", server, login);
var lease = pool.GetPooledObject(null, null, 5000);
var workspace = (IWorkspace)lease.SASObject;
keeper.AddObject(1, workspace.UniqueIdentifier, workspace);
try
{
using (var conn = new OleDbConnection("Provider=SAS.IOMProvider.1; Data Source=iom-id://" + workspace.UniqueIdentifier))
{
// throws System.Data.OleDb.OleDbException: 'The object 1EFCE532-99BA-4A27-AF37-574EAE1CD04C could not be found; make sure it was previously added to the object keeper.'
conn.Open();
}
}
catch (Exception ex)
{
System.Console.Error.WriteLine(ex.ToString());
return 1;
}
finally
{
keeper.RemoveObject(workspace);
lease.ReturnToPool();
pool.Shutdown();
}
return 0;
}
Is there a way to use SAS connection pooling with the SAS OLE DB provider?
Got a good answer to this question from SAS Support. When using a connection pool, you have to cast the workspace to IServerStatus and connect using its ServerStatusUniqueID property instead of IWorkspace.UniqueIdentifier.
var pool = factory.ObjectPools.CreatePoolByServer("Pool1", server, login);
var lease = pool.GetPooledObject(null, null, 5000);
var workspace = (IWorkspace)lease.SASObject;
var status = (IServerStatus)lease.SASObject;
keeper.AddObject(1, workspace.UniqueIdentifier, workspace);
using (var conn = new OleDbConnection("Provider=SAS.IOMProvider.1; Data Source=iom-id://" + status.ServerStatusUniqueID))
{
// success
conn.Open();
}
keeper.RemoveObject(workspace);
lease.ReturnToPool();
We are using Microsoft Enterprise library to access the sql server database.We are
having some doubts about how to close the DB Connection.Code is given below.
DatabaseFactory.SetDatabaseProviderFactory(new DatabaseProviderFactory(), false);
Database db = new DatabaseProviderFactory().Create("Dataconnectionstring");
string sqlCommand = "";
DbCommand dbCommand = db.GetStoredProcCommand(sqlCommand);
dbCommand.CommandTimeout = 0;
try
{
success = Convert.ToInt32(db.ExecuteScalar(dbCommand));
return success;
}
so how can we close database connection.
One way to do this is use using statements.
All Objects that are implementing IDisposable can be used in such way, when code reaches the closing bracket it calls Dispose() that is supposed to get rid of the object.
DatabaseFactory.SetDatabaseProviderFactory(new DatabaseProviderFactory(), false);
int success = 0;
using (var db = new DatabaseProviderFactory().Create("Dataconnectionstring"))
{
string sqlCommand = "";
using (var dbCommand = db.GetStoredProcCommand(sqlCommand))
{
dbCommand.CommandTimeout = 0;
try
{
success = Convert.ToInt32(db.ExecuteScalar(dbCommand));
}
}
}
return success;
I need to create an application for monitoring SQL Server 2000 Agent Job status and info when Job occur same as show on Windows application event log. Now I connect to the database already via a connection string, but I don't know how to get the status and info from Job.
I need to show status and info on Textbox.
What do you suggestion how to do.
Developer tools :

I am a rookie programmer.
i can do this already...
i select form table "Sysjobserver" in database "msdb" for read status, date, time of job that i want.
use this code
public void GetJobsAndStatus()
{
string sqlJobQuery = "select j.job_id, j.name, j.enabled, jh.run_status," +
" js.last_outcome_message, jh.run_date, jh.step_name, jh.run_time" +
" from sysjobs j left join sysjobhistory jh on (j.job_id = jh.job_id)" +
" left join sysjobservers js on (j.job_id = js.job_id)" +
" where jh.run_date = (select Max(run_date) from sysjobhistory)" +
" and jh.run_time = (select Max(run_time) from sysjobhistory)";
// create SQL connection and set up SQL Command for query
using (SqlConnection _con = new SqlConnection("server=10.15.13.70;database=msdb;user id=sa;pwd="))
using (SqlCommand _cmd = new SqlCommand(sqlJobQuery, _con))
{
try
{
// open connection
_con.Open();
SqlConnection.ClearPool(_con);
// create SQL Data Reader and grab data
using (SqlDataReader rdr = _cmd.ExecuteReader())
{
// as long as we get information from the reader
while (rdr.Read())
{
Guid jobID = rdr.GetGuid(0); // read Job_id
string jobName = rdr.GetString(1); // read Job name
byte jobEnabled = rdr.GetByte(2); // read Job enabled flag
int jobStatus = rdr.GetInt32(3); // read last_run_outcome from sysjobserver
string jobMessage = rdr.GetString(4); // read Message from sysjobserver
int jobRunDate = rdr.GetInt32(5); // read run_date from sysjobhistory
string jobStepName = rdr.GetString(6); // read StepName from sysjobhistory
int jobRunTime = rdr.GetInt32(7); // read run_time from sysjobhistory
String[] lviData = new String[] // ตัวแปรอะเรย์ชื่อ lviData
{
jobID.ToString(),
jobName.ToString(),
jobStepName.ToString(),
jobMessage.ToString(),
jobStatus.ToString(),
jobRunDate.ToString(),
jobRunTime.ToString(),
//jobEnabled.ToString(),
};
newData = lviData;
DisplayList(); // for display data on datagridview
}
rdr.Close();
}
}
thank you for everybody help very much. :-D
SQL stored procedures of queries don't give you any system data unless you have db_owner rights on the msdb system database, at lease in SQL Server 2008. Therefore mentioned methods normally don't work for applications where you want to show or manage jobs. However SMO namespace provides you with managed code solution for many SQL Server management features, including the SQL Server Agent functions that only require SQLServerAgent* permissions that you normally could get sorted for your application user. A good intro of using SMO classes to work with jobs is given here:
http://www.codeproject.com/Tips/367470/Manage-SQL-Server-Agent-Jobs-using-Csharp
I work on a similar task now and whilst SQL queries give me access denied, with C# code and Microsoft.SqlServer.Management.Smo.Agent namespace I just listed all jobs with this code:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using Microsoft.SqlServer.Management.Smo;
using Microsoft.SqlServer.Management.Common;
using Microsoft.SqlServer.Management.Smo.Agent;
namespace SmoTest
{
class Program
{
static readonly string SqlServer = #"SQL01\SQL01";
static void Main(string[] args)
{
ServerConnection conn = new ServerConnection(SqlServer);
Server server = new Server(conn);
JobCollection jobs = server.JobServer.Jobs;
foreach (Job job in jobs)
{
Console.WriteLine(job.Name);
}
}
}
}
This should be a good starting point to find out how to find your SQL Agent jobs using T-SQL:
View (and disable) SQL Agent Jobs with TSQL
The script will list out all your jobs on your database, and when they will be run next and so forth.
Using the job_name, you should also be able to find out details about your jobs using the SQL Server Agent Stored Procedures in the msdb database on your server.
On SQL Server 2005 and above, you can use the system stored procedure msdb.dbo.sp_help_job to get information, including status, about SQL Server Agent Jobs. You can read more about sp_help_job at http://msdn.microsoft.com/en-us/library/ms186722(v=SQL.90).aspx.
Here is the sample code to do this from C#.
private Dictionary<int, string> ExecutionStatusDictionary = new Dictionary<int, string>()
{
{0, "Not idle or suspended"},
{1, "Executing"},
{2, "Waiting for thread"},
{3, "Between retries"},
{4, "Idle"},
{5, "Suspended"},
{7, "Performing completion actions"}
};
public string GetStatus()
{
SqlConnection msdbConnection = new SqlConnection("Data Source=SERVERNAME;Initial Catalog=msdb;Integrated Security=SSPI");
System.Text.StringBuilder resultBuilder = new System.Text.StringBuilder();
try
{
msdbConnection.Open();
SqlCommand jobStatusCommand = msdbConnection.CreateCommand();
jobStatusCommand.CommandType = CommandType.StoredProcedure;
jobStatusCommand.CommandText = "sp_help_job";
SqlParameter jobName = jobStatusCommand.Parameters.Add("#job_name", SqlDbType.VarChar);
jobName.Direction = ParameterDirection.Input;
jobName.Value = "LoadRegions";
SqlParameter jobAspect = jobStatusCommand.Parameters.Add("#job_aspect", SqlDbType.VarChar);
jobAspect.Direction = ParameterDirection.Input;
jobAspect.Value = "JOB";
SqlDataReader jobStatusReader = jobStatusCommand.ExecuteReader();
while (jobStatusReader.Read())
{
resultBuilder.Append(string.Format("{0} {1}",
jobStatusReader["name"].ToString(),
ExecutionStatusDictionary[(int)jobStatusReader["current_execution_status"]]
));
}
jobStatusReader.Close();
}
finally
{
msdbConnection.Close();
}
return resultBuilder.ToString();
}
You can get a list of all server jobs using this SELECT:
SELECT [name] FROM msdb.dbo.sysjobs
If you'd like to get a list of currently running jobs and their information, I would recommend writing a stored procedure in SQL which your application calls. There's a good demonstration here you could use...

Good luck!
For my use case, I specifically needed to know when the job was finished running, and whether or not it succeeded. Here is my code to do that:

Note that you may need database/server owner permissions or something like that for this code to work.
I have two parts to my application which both does massive amount of insert and update respectively and because or poor managemenent, there's deadlock.
I am using entity framework to do my insert and update.
The following is my code for my TestSpool program. The purpose of this program is to insert x number of records with a given interval.
using System;
using System.Linq;
using System.Threading;
using System.Transactions;
namespace TestSpool
{
class Program
{
static void Main(string[] args)
{
using (var db = new TestEntities())
{
decimal start = 700001;
while (true)
{
using (TransactionScope scope = new TransactionScope())
{
//Random ir = new Random();
//int i = ir.Next(1, 50);
var objs = db.BidItems.Where(m => m.BidItem_Close == false);
foreach (BidItem bi in objs)
{
for (int j = 0; j <= 10; j++)
{
Transaction t = new Transaction();
t.Item_Id = bi.BidItemId;
t.User_Id = "Ghost";
t.Trans_Price = start;
t.Trans_TimeStamp = DateTime.Now;
start += 10;
db.Transactions.AddObject(t);
}
Console.WriteLine("Test Spooled for item " + bi.BidItemId.ToString() + " of " + 11 + " bids");
db.SaveChanges();
}
scope.Complete();
Thread.Sleep(5000);
}
}
}
}
}
}
The second part of the program is the testserverclass, the serverclass supposed to processed a huge amount of transactions from testspool and determined the highest amount of the transaction and update to another table.
using System;
using System.Linq;
using System.Transactions;
public class TestServerClass
{
public void Start()
{
try
{
using (var db = new TestServer.TestEntities())
{
while (true)
{
using (TransactionScope scope = new TransactionScope())
{
var objsItems = db.BidItems.Where(m => m.BidItem_Close == false);
foreach (TestServer.BidItem bi in objsItems)
{
var trans = db.Transactions.Where(m => m.Trans_Proceesed == null && m.Item_Id == bi.BidItemId).OrderBy(m => m.Trans_TimeStamp).Take(100);
if (trans.Count() > 0)
{
var tran = trans.OrderByDescending(m => m.Trans_Price).FirstOrDefault();
// TestServer.BidItem bi = db.BidItems.FirstOrDefault(m => m.BidItemId == itemid);
if (bi != null)
{
bi.BidMinBid_LastBid_TimeStamp = tran.Trans_TimeStamp;
bi.BidMinBid_LastBidAmount = tran.Trans_Price;
bi.BidMinBid_LastBidBy = tran.User_Id;
}
foreach (var t in trans)
{
t.Trans_Proceesed = "1";
db.Transactions.ApplyCurrentValues(t);
}
db.BidItems.ApplyCurrentValues(bi);
Console.WriteLine("Processed " + trans.Count() + " bids for Item " + bi.BidItemId);
db.SaveChanges();
}
}
scope.Complete();
}
}
}
}
catch (Exception e)
{
Start();
}
}
}
However, as both application con-currently runs, it will go into deadlock pretty fast randomly either from the first test or server application. How do i optimised my code for both side to prevent deadlocks ? I am expecting huge amount of inserts from the testspool application.
Since they work on the same data and get in each others way, I believe the cleanest way to do this would be to avoid executing these two at the same time.
Define a global static variable, or a mutex or a flag of some kind, maybe on the database. Whoever starts executing raises the flag, other one waits for the flag to come down. When flag comes down the other one raises the flag and starts executing.
To avoid long wait times on each class you can alter both your classes to process only a limited amount of records each turn. You should also introduce a maximum wait time for the flag. Maximum record limit should be chosen carefully to ensure that each class finishes its job in shorter time than max wait time.
