Windows server uses the batch processing script to determine the port, start tomcat, and batch process tomcat The tomcat on the Windows server always hangs out from time to time. Therefore, the scheduled operation script is used to determine whether port tomcat80 is running. If it is run, it is skipped. If it is down, tomcat is started, solve the Problem of busin

I have been engaged in several video codec quality analyses recently. I need to write several scripts and found that in addition to the powerful functions of Python, basic doscommands are also necessary. So I have read several articles.

Sometimes JDBC is not running fast enough, which allows some programmers to use database-related stored procedures. As an alternative, you can try to use the batch processing feature of Statement to see if all SQL statements can be executed at the same time to increase the speed.The simplest form of a stored procedure is to include a series of SQL statements. Putting these statements together facilitates ma

Sometimes, not only do we have to deal with a picture, we may also process a batch of pictures. At this point, we can do the processing through loops, or we can call the collection of pictures that the program comes with.The picture collection functions are:skimage.io.ImageCollection(Load_pattern,load_func=none)This function is placed in the IO module, with two parameters, the first parameter Load_pattern,

Recently doing a thing, written in PHP, because the database to read the name of the picture, and then access to the corresponding image, read the size of the picture and resolution, re-deposited into the database. The amount of data is now 5,000, and if not set, the default maximum execution time for PHP is 30 seconds. So in 30 seconds, I can only handle 700, just start manually, 700, 700 of the execution. Later, I feel that this will not work, the amount of data will be over 10W, it would be

As we all know, batch processing runs a single process step by step, but if the process execution is slow, such as ping an inaccessible IP address, it will greatly affect the execution efficiency of the batch processing program. The following is a simple example. In Windows, you can use
