I am trying to evaluate Quartz.Net. I tested it with adding a class which implemented IJob in the executing assembly and it worked. Now I want to develop an Job Scheduler in which I can add jobs at runtime. How to proceed. Edit: If it seems subjective I have following specific question. How to add external class/dll which are unkno...
In linux kenel process scheduler there is a priority type SCHED_FIFO. I want to change the scheduling policy. I have two questions: 1- Where, in the kernel source code, is it mentioned that after a tick the cpu should belong to the interrupted process(Because in FIFO the process should remain until it finishes)? 2- In SCHED_RR where th...
I have a simple quartz trigger running in Spring 2.5.6-SEC01. Trigger definition looks like this: <bean id="AdvicesCronTrigger" class="org.springframework.scheduling.quartz.CronTriggerBean"> <property name="jobDetail" ref="AdvicesQuartzJob"/> <property name="cronExpression" value="0 20/15 * * * ?"/> </bean> This is my schedul...
Who schedules the scheduler? Which is the first task created and how is this first task created? Isn't any resource or memory required for it? isn't like a chicken and egg scenario? Isn't scheduler a task? Does it get the CPU at the end of each time slice to check which task needs to be given CPU? Are there any good links which makes...
Where in the boot process does the "scheduler" get created and when created how can its instructions be accessed? ...
I'm trying to make a simple scheduler service that will automatically send emails, etc. For now I have simple WCF service in which I create an instance of a timer, set a callback and do some work in the callback. Now this part works fine, with the callback being called and the work in it being done as expected. The issue is I need to m...
I have class A and list of A objects. A has a function f that should be executed every X seconds (for the first instance every 1 second, for the seconds instance every 5 seconds, etc.). I have a scheduler class that is responsible to execute the functions at the correct time. What i thought to do is to create a new class, ATime, that wil...
Hello, I'm doing some kind of performance evaluation using two different vanilla Linux kernels, 2.6.22 and 2.6.31, since I assume each of them uses a different scheduling mechanism: 2.6.22 uses the old O(1) scheduler, whilst 2.6.31 adopts the CFS. Could anybody confirm the correction of this assumption? ...
Websphere Scheduler is using scheduler datasource XA driver . When task is executed by scheduler it is starting a global transaction, but in our application we are creating a new connection to another database and explicitly commiting the data and closing the connection. This data source configured using non-XA driver datasource. For the...
Anybody have experience or thoughts on a scheduler to couple with a persistent Gearman queue? Obviously there's crontab available, but i'd like some more functionality. We're looking at Java Quartz. Please weigh in if you've done this before in any capacity! ...
I'm using perl cron, and I want to make a rule like this run every xx min/hours starting at yy:yy time (until the end of time) How would I put this into a cron string? perl:cron seems to use the same syntax as regular cron so a regular cron string should work TIA! ...
Hi All I am currently working on an ASP.NET application in VB.NET and one of its functions is to use the Windows Task Scheduler. The application will need pretty much full control over this as it needs to Create, Modify, Delete and Run tasks. I found this library to help with the whole thing and it works well but only locally on my Win...
Hi Guys My Company is running a lots of batch jobs to process data for partners. We used to use sql server agent to execute batch process. I found it's very difficult to get batch process information like log or status when i working on sql server's agent. So I'd like to change my company's job scheduling process to another stable sol...

Hi, I want to use a Scheduler like Telerik Scheduler in my Mvc project. The problem is that the Scheduler is a Asp.Net WebForm control. For this reason, I must create a WebForm page in my Mvc project to put the Scheduler control. When I show the page, it work fine to render the layout of the control but if I try to interact with it; c...
I run massively parallel scientific computing jobs on a shared Linux computer with 24 cores. Most of the time my jobs are capable of scaling to 24 cores when nothing else is running on this computer. However, it seems like when even one single-threaded job that isn't mine is running, my 24-thread jobs (which I set for high nice values)...
This is really annoying me as I have done it before, about a year ago and I cannot for the life of me remember what library it was. Basically, the problem is that I want to be able to call a method a certain number of times or for a certain period of time at a specified interval. One example would be I would like to call a method "x" s...
Hello All, Would like to know how the scheduler gets called so that it can switch tasks. As in even if its preemptive scheduling or round robin scheduling - the scheduler should come in to picture to do any kind of task switching. Supposing a low priority task has an infinite loop - when does the scheduler intervene and switch to a high...
Hi all We need to develop a notifier component. What it will do, is to scan a database at given intervals (say, every 15th minute), to see if any notifications needs to be sent out. We're running on Windows, and so we've been looking into either a Windows Service or the Windows Task Scheduler. Our biggest concern is the robustness of ...
I understand that Gang scheduling is a scheduling algorithm for parallel systems that schedules related threads or processes to run simultaneously on different processors. Gang scheduling is used so that if two or more threads or processes communicate with each other, they will all be ready to communicate at the same time. However, how...
