then wrote some test code, found to be the database connection pool problem, due to open a lot of threads, the database connection is not enough to use, so the card is there, changed the C3P0 connection pool settings just fine.Of course, if the number of concurrent connections is too many for the performance of the database, the CPU frequency will increase. In the current situation, the number of clients is not a problem, if the number of clients is too much, it needs to be handled in other way

Iv. string Interpretation execution In some programming languages, a special function can be inserted into the input string to deceive the server into performing additional, redundant actions. The following Perl code is an example: = "Mail Body"; System ("/usr/sbin/sendmail-t Obviously, the code can be used as part of a CGI program, or it can be invoked from the command line. In general, it can be invoked a

Java Server page (JSP), and ASP, PHP is the same as the network programming language, but the JSP page inserted in the script code is a Java statement fragment. To use JSP to write an application, first of all, must have a Web server that can execute JSP script, can build on

Original address: Lax Language TutorialsAndrew BinstockEvery year in the review of Jolt Awards books, I will be a number of language tutorial books are exhausted. Judging from these years of experience, these language tutorials are well written, but in addition, there are few bright spots. In other words, these books are very rigorous, very sophisticated, if the reader has sufficient strength, through their mastery of a language programming technology

advanced Programming, the book includes the following: Set up specific programming conventions for team development use tools (such as JSLint and Jshint) to get the team developing to the right track build coding style manuals (such as basic formatting), Help development team move from "guerrilla" to "regular" application pr
