ABP IO Background job is not getting triggered. #605 | Support Center | ABP Commercial

suraj.kumbhar created 3 years ago

ABP Commercial version: v3.2.1
UI type: Razor
Tiered (MVC) or Identity Server Seperated (Angular): no
Exception message and stack trace:
Steps to reproduce the issue: Database : MongoDB

We have followed this document link https://docs.abp.io/en/abp/latest/Background-Jobs to crate a job and implemented exactly like this but somehow that job is not getting triggered and as soon as entry get added in Background Table IsAbandoned flag set to true. Sometimes we also observed this behaviour is that it suddendly start executing job and again stopped working. Cean -> rebuild- > build project is working some times. its a weird things we are obeserving. Here is the sample code,

public enum ImportTableName
{
    Test1 = 1,
    Test2 = 2
}

[BackgroundJobName("ImportJob")]
public class BackgroundImportJobArgs
{
	public string FilePath { get; set; }
	public ImportTableName ImportTableName { get; set; }
}

public class BackgroundImportJob : AsyncBackgroundJob<BackgroundImportJobArgs>, ITransientDependency
{
	private readonly IImportTblAppService importTbl;

	public BackgroundImportJob(IImportTblAppService importTbl)
	{
		this.importTbl = importTbl;
	}

	public override async Task ExecuteAsync(BackgroundImportJobArgs args)
	{
		switch (args.ImportTableName)
		{
			case ImportTableName.Test1:
				await importTbl.AddTest1(args.FilePath, args.ImportTableName);
				System.IO.File.Delete(args.FilePath);
				break;
			default:
				break;
		}
	}
}
    
public class ImportTblAppService : DemoAppService, IImportTblAppService
{
	private readonly ITest1Repository _test1Repository;
	private readonly IBackgroundJobManager _backgroundJobManager;
	public ImportTblAppService(ITest1Repository test1Repository, IBackgroundJobManager backgroundJobManager)
	{
		_test1Repository = test1Repository;
		_backgroundJobManager = backgroundJobManager;
	}

	public async Task AddTest1(string filePath, ImportTableName tablename)
	{
		/* Here contains Insert Logic */
	} 

	public async Task ScheduleImportJob(string filePath, ImportTableName tablename)
	{
		await _backgroundJobManager.EnqueueAsync(new BackgroundImportJobArgs { FilePath = filePath, ImportTableName = tablename }).ConfigureAwait(false);
	}
}

hi

When IsAbandoned is true, it means that an exception has occurred.

Can you check the logs of your application?

This is my test application service.

It works, but there will be a few exceptions. My local mongodb will not get an exception. I think it may be caused by your mongodb.

/* Inherit your application services from this class.
 */
public abstract class MyAppAppService : ApplicationService
{
	protected MyAppAppService()
	{
		LocalizationResource = typeof(MyAppResource);
	}
}


public enum ImportTableName
{
	Test1 = 1,
	Test2 = 2
}

[BackgroundJobName("ImportJob")]
public class BackgroundImportJobArgs
{
	public string FilePath { get; set; }
	public ImportTableName ImportTableName { get; set; }
}

public interface IImportTblAppService : IApplicationService
{
	Task AddTest1(string filePath, ImportTableName tablename);
}

public class BackgroundImportJob : AsyncBackgroundJob<BackgroundImportJobArgs>, ITransientDependency
{
	private readonly IImportTblAppService importTbl;

	public BackgroundImportJob(IImportTblAppService importTbl)
	{
		this.importTbl = importTbl;
	}

	public override async Task ExecuteAsync(BackgroundImportJobArgs args)
	{
		Console.WriteLine("ExecuteAsync");

		await importTbl.AddTest1(args.FilePath, args.ImportTableName);
	}
}

public class ImportTblAppService : MyAppAppService, IImportTblAppService
{
	private readonly IBackgroundJobManager _backgroundJobManager;
	public ImportTblAppService(IBackgroundJobManager backgroundJobManager)
	{
		_backgroundJobManager = backgroundJobManager;
	}

	public Task AddTest1(string filePath, ImportTableName tablename)
	{
		Console.WriteLine("AddTest1");

		return Task.CompletedTask;
	}

	public async Task ScheduleImportJob(string filePath, ImportTableName tablename)
	{
		await _backgroundJobManager.EnqueueAsync(new BackgroundImportJobArgs { FilePath = filePath, ImportTableName = tablename });

I think this issue is only because of MongoDB, we are suing Azure CosmosDB with Mongo API Version 3.6 also. It has already issue present from last 2 months https://support.abp.io/QA/Questions/473/MongoDBDriverMongoCommandException-Command-aggregate-failed-Error2-After-deployment-on-Azure-using-CosmosDB.

Due to above issue we have choose to use 3.2 version for mongo in Cosmos and we started working. But when we want to implement Backgroung job its not working.

We have to use MongoDb only. Please suggest a workaround above issues. It has performance issue, Aggregation Issues, Background job is not getting triggered.

hi

Because you don't always get this exception, maybe you can use try-catch to retry.
