schedule

This question is an exact duplicate of: Linux task schedule to Hour, minute, second 1 answer I just want to run a shell scrip at say this exact time "16:22:36". utilities like "at" are useless since they don't have "seconds". "sleep" does not work since the loop is ending 8 hours ahead of time for some reason :s , I have searched all over google and couldn't find any tools. so a huge Os like Linux doesn't have a proper task scheduler? The standard cron lacks second precision scheduling because Unix server administration traditionally rarely needed one-second precision It might be used in such

I'm relatively new to Java and I've pick up a project to work on. However, I've run into a block. I need a method to run at a certain times throughout the day. I've done quite a bit of searching but I can't find anything that seems like it would do the trick. I've run into the Timer class but it appears to run at certain intervals. The Scheduler class, appeared to have the same issue. I also came across Quartz but I think I need something more lightweight and I could only see how to do things at intervals. Perhaps, just because I'm new, I've missed some things that could help me in these

I am trying to figure out the possibilities I have to solve the following problem. a) I want to have a database table that uses "crontab syntax" to schedule tasks, the structure would be something like this: |-Id-|---Crontab Syntax---|---------Task----------| | 1 | 30 * * * * * | MyClass.TaskA(args[]) | | 2 | 0 1 * * 1-5 * | MyClass.TaskB(args[]) | | | | | The above table will be modified at any time by an external application. Tasks added or removed should instantly affect the scheduler. b) The scheduler itself should reside on a Java application server. It should constantly be synched with

How can I configure a schedule intervals: @Schedule(persistent=true, minute="*", second="*/5", hour="*") outside of the application code? How can I configure it in ejb-jar.xml? Can I configure it outside the application (kind of properties file)? Here is an example of a scheduling in the deployment descriptor: <session> <ejb-name>MessageService</ejb-name> <local-bean/> <ejb-class>ejb.MessageService</ejb-class> <session-type>Stateless</session-type> <timer> <schedule> <second>0/18</second> <minute>*</minute> <hour>*</hour> </schedule> <timeout-method> <method-name>showMessage</method-name> <

I got a problem with the Primefaces <p:schedule> . It is not displayed in my Application which uses <ui:include> and <ui:composition> Tags. But if I place the Schedule in a Standalone Page without these Tag Combination, it works as expected. My app.xhtml Page includes a Layout which is defined by the <p:Layout> Component. I define a Menu at the left side with a <f:ajax> Tag, so that a contentPanel get updated on each click in the menu. One of these Pages which gets included, is the hldyplanning.xhtml - in this Page a <p:schedule> should be displayed. For testing I create a new site. The test

I am using Major upgrade early scheduling in my WIX Setup projects as below. I prefer to clear all files on upgrades. However I need to preserve a config file and restore again on upgrade. I don't want to change this early scheduling (Schedule="afterInstallInitialize"), as I will be ended with other issues. Is there any work around (Custom Actions?) to preserve the config file in the above early scheduling? The way I deal with this problem is to have two files. You'll notice that app.config/web.config files appSettings element has a file attribute. If you store your user data there the
