good idle games

During struts2 and spring websites, after the system is idle for a period of time, an error will occur while accessing the page. The second visit will be normal. Later, I checked the background log and found that the database connection was closed, resulting in page access errors. A null pointer error is reported on the page. The error is not retained. The errors recorded in the log are as follows:ERROR (java. SQL. Connection: 19)-Error calling Connec

The system administrator must maintain the healthy operation of their servers. One important part of this is memory. When server memory usage is too high, it degrades server performance.

Use terminal ssh to connect to the server, if there is no operation for a long time, it will be disconnected. If you want to use it, you have to re-login, which is very inconvenient, but also affect the development efficiency.In view of this problem, theoretically, there are two kinds of schemes:1. Modify the server Sshd_config file2. Modify the user's CRT link how often to send a stringModification of the server is unlikely, standing in the manager's perspective to think about the problem, to m
