See http://www.ibm.com/developerworks/cn/java/j-quartz/ Quartz is an open source project that provides a wide range of Job Scheduling sets. In this article, Software Engineer Michael Lipton and IT architect soobaek Jang introduced the quartz API, starting from a general overview of the framework, end with a series of code examples that demonstrate basic features of quart. After reading this article and reading the sample code, you should be able to a

Cocos2d-x Study Notes (10) scheduler and Cocos2dx callback Preface After reading the first nine learning notes, we can basically make some simple interfaces. But what if we want to keep things moving? The answer is simple. Use schedle. Let's take a look at the usage of schedule. Scheduler usage In the previous CCNode study, we introduced some schedule methods. Now let's review: // Return whether the specif

Linux Task Scheduler CronLinux Task Scheduler: Automatically executes commands or scripts at a certain time.Configuration file for Task Schedulercat /etc/crontabThe first two lines are defined variables, the third line is to send the message to whom, and then the last line has five * (asterisks) corresponding to five bits, that is, the above five elements, the following to explain what the difference means:

;} Here, let's talk about normalization (normalization), a somewhat obscure term. If you have done audio and video fixed-point algorithm optimization, should be not unfamiliar with the word. Different fixed-point data have different representations, there are Q31, there are Q15, the location of the decimal point of the data is different, can not be compared, add and subtract operations, so need to be normalized, all converted to a specific data format (in fact, the location of the decimal p

Recurring Process (Task Scheduler)Task Scheduler: Perform one or a series of tasks at some point in the future. Execution results are sent to the administrator in the form of a messageWhen Cron starts, he reads the configuration files, saves them in memory, and then goes to sleep. Every minute, Croon wakes up, checking the crontab file for modification times. Reload any changed files, and then in return to

Introduction to new database management features IBM IDS 11 provides a new set of expected features that form the basis of RDBMS self-management. These tools enable DBAs to collect server information and adjust the database server using SQL as a remote administration tool. In addition, the scheduler can also schedule the execution of SQL API commands, much like the Unix®cron task. IBM IDS itself is a reputable management-free database, and now lowers

If you set the task to run at 2 o'clock in the morning. But you were after 2 o'clock.The program is released or restarted, in which case the task executes immediately, rather than waiting until 2 o'clock in the morning the next day. In order to avoid

The first step is to go into the admin tool, find the Task Scheduler, and then open it and see that there are a lot of options on the main page, and then I click on the first folder under the program and it's easy to look at the picture. And then came out of the subfolder of the page, there are a lot of features, and then I saw my computer service is not turned on, is disabled, and then I will be the service program features open, and then the la
