typo3 fastcgi scheduler
I’ve installed a TYPO3 schedule but it doesn’t schedule. I’ve setup a cron job every 5 minutes to run TYPO3 scheduler and in my syslog it prints me the line: Oct 6 14:00:01 server /USR/SBIN/CRON[31775]: (root) CMD (/usr/local/bin/php /var/www/typo3/cli_dispatch.phpsh scheduler) hence I think the cron job is working but in my TYPO3 backend I can’t see the schedule. It seems that TYPO3 script isn’t started properly. When I run cli_dispatch.phpsh from the shell it gives me many strange errors. The

c linux kernel real-time scheduler
I am experimenting with SCHED_FIFO and I am seeing some unexpected behaviour. The server I am using has 12 cores with hyper-threading disabled. All configurable interrupts have been set to run on CPU 0.My program starts creates a thread for lower priority tasks using the pthreads library without changing the scheduling policy with CPU affinity set to core 0. The parent thread then sets its CPU affinity to core 3 and its own scheduling policy to SCHED_FIFO using sched_setscheduler() with pid z

python wmi scheduler
I am fairly new to python and as part of a program I am creating I am trying to use WMI to get a listing of all processes running and their current processor utilization. I’m also using threading event scheduler to call this every 30 seconds.import wmi from threading import Timer import timec = wmi.WMI() time_to_sleep = 30def get_process_info():process_info = {} try:for process in c.Win32_Process ():id = process.ProcessIDfor p in c.Win32_PerfRawData_PerfProc_Process (IDProcess=id):n1, d1 = l

linux kernel scheduler coredump
I’m currently developing a crash collection mechanism that uses a custom core format. In essence it hooks the linux_binfmt->core_dump entries to point to our dumper.The dumper itself launches a usermode helper with the PID of the process to capture which dumps the process information via ptrace before allowing the kernel to fully kill the process:call_usermodehelper(argv[0], argv, envp, UMH_WAIT_PROC);My issue is that the task is technically in a disk sleep state and not stopped so ptrace calls

enterprise scheduler
I’m curious how banks handle recurring tasks of their users. And if they have thousands of those tasks, for example paypal recurring payments, how does paypal handle them? What software they use? I dont think they use cron\quartz for such tasks.What do they do if system goes down and unable to process user tasks?Is there any solution like mysql has with event scheduler? Have anyone tried RabbitMQ to process various events?

c linux scheduler affinity
I wanted to study how threads can be assigned manually to specific cores on a multi core machine. I found that include/sched.h defines some macros and functions (sched_setaffinity, etc.)that can help for this. However, the functions are extern’ed and I can’t find their definitions. Are those functions implemented anywhere? If yes, where and is it possible to override the default implementation? If no, how can I implement them?And would adding new implementation imply that I have to recompile my

java android service android-service scheduler
On my device runs a service in an app (its not my app and I cannot uninstall it and my device is not rooted) that is always draining power. I can stop that service in my devices application settings but is there a way to stop it programatically, so I don’t have to do that manually all the time ?Could maybe something like stopService(…); work ?Is there maybe a way to change the scheduler to prevent the restarts of the service ?”W/ActivityManager(178): Scheduling restart of crashed service xxxx

c++ logging scheduler
I am not sure if this is even a valid question. I am not a master at understanding the workings of system. One of my program writes logs to a text file. Another email program runs on scheduler and emails and archives the log file if found in the folder.My question is, If at any given instant if the first program is writing information into the file and at the same time email scheduler runs what will happen? Will the email program be able to mail the file and archive it? If Yes, will the earlier

linux linux-kernel scheduler
I have a process running on Linux which creates a lot of pThreads (each of them have its own purpose). Let’s say by some reason one of threads crashes. Sometimes, crash might be caused by some other thread and it would be good to know what threads were running before the crashed one.So the question is: Is there a way to ask Linux scheduler what last threads were scheduled?Any help is really appreciated. Thanks.

c# asp.net scheduler
In my application data is stored in a .config file,(in XML format). User is able to set date on which he wants mail (like reminder through mail). So there should be a scheduler which will execute daily to send mails on target date to users. As there is no database interaction how is it possible to run scheduler?I am totally blank about this task. Can anyone help me? Thanks in advance.

java exception quartz-scheduler scheduler
I have a web application with scheduled jobs using the Quartz library. Recently I encountered cases where a job didn’t seem like it was being fired. I did some reading and apparently if the job throws an exception, the Quartz scheduler will attempt to execute the job again. Is this true?In any case, I did some troubleshooting based on the assumption that the above statement is true. So let’s say I have the following code snippet:try {method.invoke(object, params); } catch (ExceptionA ea) {ea.pri

java concurrency scheduler
I need some sort of a task scheduler, which will schedule execution of a task (once) and monitor if the task is still ‘alive’, so if some uncaught exception will happen (like IOexception, or database connection failure) – the scheduler will re-start the task from scratch. I don’t want to catch Throwable in the while(true) loop, just want to let it fail.Ideally, new thread should be created.Is there something ready-to-use? Its straightforward to implement this kind of scheduler with ThreadFactory

javascript extjs scheduler
I am attempting to change the calendar header date layout in EXT Scheduler. I’ve copied the section of code from the customer header demo, made a few changes, and dropped it into my code.The problem is I get “Sch.preset is undefined”, where I’m executing “Sch.preset.Manager.registerPreset(“weekView”, weekView);”. I’m not sure of this is a scoping issue or whether I’m missing some code completely. Ext.onReady(function () {var weekView = {displayDateFormat : ‘Y-m-d’,shiftIncrement : 1,shiftUnit :

python cmd scheduler python-idle
I have a script that works in IDLE but not when I run the same script in cmd. Then I get this error:File “C:\Python27\lib\encodings\cp850.py”, line 12, in encode return codecs.charmap_encode(input,errors,encoding_map) UnicodeEncodeError: ‘charmap’ codec can’t encode character u’\u2013′ in position 17: character maps to <undefined>The error occurs when I try to print a string that contains the following part ” – “. When the script is run in IDLE everything works perfectly. I use Python 2.7

mysql database events scheduler
I have a PHP application that allows admin users to add new events, edit them and delete them for customers to book. What I want to do is automatically delete events after they have happened. Each event record in the events table (ID, Start_Date, Course_ID, Place) has a start date so I basically want the database to ask every day ‘Are there any records in the events table where Today’s Date > Start_Date’. If there are, they must be deleted. I have been reading this web page http://www.sitepoint.
