Tomcat For Mac function introduction

Tomcat server is a free and open source web server Application server is a lightweight application server. It is commonly used in small and medium-sized systems and situations where there are not many concurrent access users. It is used to develop and debug JSP. Program of choice. For a beginner, you can think of it this way, when configuring Apache on a machine The server can use it to respond to access requests for HTML (an application under the Standard Universal Markup Language) page. Actually Tomcat is partly Apache An extension to the server, but it runs independently, so when you run tomcat, it actually runs as a separate process from Apache.

Tomcat was originally developed by James Duncan Davidson, a software architect at Sun. He later helped turn it into an open source project and was contributed by Sun to the Apache Software Foundation. Since most open source projects O'Reilly will publish a related book and design its cover to be a sketch of an animal, he wanted to name the project after an animal. Because he wanted the animal to be able to take care of itself, he eventually named it Tomcat (English tomcat or other male cat). The book introducing Tomcat published by O'Reilly (ISBN The cover of 0-596-00318-8)[1] is also designed to look like a male cat. Tomcat's logo and mascot is also designed as a male cat.

Tomcat For Mac FAQ

​​​How to adjust memory settings in Tomcat For Mac?

​​​​​First look at java -X determines which parameters to set. You can then set them via the environment variable CATALINA_OPTS. Read the comments at the top of the file catalina.bat or catalina.sh for more information about CATALINA_OPTS.

​ ​ Please note that the environment variable JAVA_OPTS also exists, but should not be used to set memory settings. The difference is that the JAVA_OPTS setting is used for all Tomcat management commands. when you stop When Apache Tomcat (using shutdown.sh or catalina.sh stop command), a short-lived small Java process will be created to notify the Tomcat master Java process it must be shut down. This small Java process does not require the same memory settings as the main process. Small processes use from Set JAVA_OPTS. The main process uses settings from JAVA_OPTS and CATALINA_OPTS.

​ ​ If you start Tomcat in any other way that does not use catalina.bat or catalina.sh to prepare the command line for Java (for example, you start it directly from the IDE java, or you use a service wrapper to run Tomcat as a service on Windows), see their options on how to provide settings for the java executable. For example, for The Apache Commons Daemon service wrapper for Windows has a GUI The configuration dialog box can be opened by running tomcat9w.exe or similar commands.

​​​Why does Tomcat For Mac version receive the OutOfMemoryError error message?

Your code is hanging on object references and the garbage collector can't do its job. Get a profiler to debug this.

You have run out of file descriptors. If you are on a *nix system, it has been observed that an OutOfMemoryError is thrown if it runs out of file descriptors. . This can happen if your threshold is too low. The ulimit program can help you here. When considering these thresholds, you may also want to consider socket connections. Google Be your friend for more information on this topic.

You have too many threads running. Some operating systems have limits on the number of threads a single process can execute. (This is the JVM.) See your operating system documentation for more information on how to raise this threshold.

If you have many servlets or JSPs, you may need to increase the permanent generation. By default it is 64MB. Doubling that - XX:MaxPermSize=256m might be a good start.

Your operating system limits the amount of memory your process may occupy. Memory profiling tools may prove the above statements wrong - but you probably don’t want to use them in a production environment
