Tomcat concurrency quota and database management system concurrency quota

Tomcat concurrency quota and database management system concurrency quota

By default, the maximum number of threads in Tomcat is 200, which means that the number of concurrent accesses cannot exceed 200,

That is, the number of concurrent requests cannot exceed 200, or Tomcat will crash.

To prevent Tomcat crash, some systems have restrictions on online users.

The database management system also has restrictions on concurrent connections.

Excessive concurrency connection may cause system crash (Tomcat will not crash );

If the concurrent request exceeds the standard, Tomcat will crash and the system will crash.
