Re: wait_timeout help

[Visolve DB Team]

Hi

Actually I don't get any idle processes listed.. but have came across such 
mails..

On which platform you are running mysql?

I guess this might be:
If Windows, the server will drop the connection probably because of 
'wait_timeout' expired.
For others, the mysql gets reconnected with 'reconnect flag' set to 1 in the 
MySQL structure...

Thanks

  Hi
  I set the wait_timeout in my.cnf.
  Sometimes it works well and there is no idle process 120 seconds time.
  But sometimes there are idle processes with 1900s time.

  What the reason can be?

    Hi

     According to the VARIABLE "wait_timeout"  [default: 28800 seconds] a 
running MySQL daemon clears up idle connections if their 
    "idle period" > "wait_timeout".    so the sleeping threads will be 
automatically cleared if the time exceeds 'wait_timeout' variable value.
    'wait_timeout' variable : The number of seconds the server waits for 
activity on a non-interactive connection before closing it. This timeout 
applies only to TCP/IP connections, not to connections made via Unix socket 
files, named pipes, or shared memory. 

    'interactive_timeout' variable's value or wait_timeout variables values 
-depends on the type of client (as defined by the CLIENT_INTERACTIVE connect 
option to mysql_real_connect())

      Thanks again 
      I have some questions that may help me explain my problem well.

      1- What's this mean:
      mysql> SHOW PROCESSLIS;
      
+------+-------+----------------------+--------+---------------+---------+--------+-----------------+
 
       | Id   | User | Host               |    db   | Command | Time | State | 
Info           |
      
+------+-------+----------------------+--------+---------------+---------+---------+----------------+
      |    1   | usr  | myhost:36336 | mydb | Sleep       | 2587  |          | 
NULL         | 
      |   11  | usr  | myhost:36341 | mydb | Sleep       | 2587  |          | 
NULL         |
      |   12  | usr  | myhost:36348 | mydb | Sleep       | 2587  |          | 
NULL         |
      | 3732| usr  | myhost:43940  | mydb | Sleep       | 2587  |         | 
NULL         | 
      
+------+-------+----------------------+--------+---------------+---------+---------+----------------+

      Are these processes idle?
      If yes why MySQL doesn't kill them?


      2- If I set wait_timeout variable, will they be killed on that time?
      3- If I set interactive_timeout, what will happen to queries that take 
time longer than interactive_timeout?

        Try command line option, like

        mysql >set @@session.wait_timeout=15;
        mysql> show variables;
