mySQL stops responding in the morning

2003-03-17 Thread amit . mehta
I have an app running on Tomcat 4.0.6. The app access mySQL  Ver 11.18
Distrib 3.23.54, for sun-solaris2.9 (sparc)
on Solaris 9.

the app runs fine during the day, but when I come back to work in the
morning, I see that the database connection has died and  mySQL does not
respond anymore.

What needs to be done to make keep it alive ?

Thanks

First you should determine whether this is really a MySQL problem or a Tomcat
problem.  When Tomcat cannot access the MySQL server, is it that the server
itself is unresponsive, or can other clients connect to it still.  For
example, if you attempt to connect with the mysql client, can you?  Or
does that fail as well?

If it is indeed MySQL that stops responding, I'd recommend to set up a 
script that would periodically try to connect to MySQL, and restarts it 
if it stops accepting connections. But try to find the real cause - I 
had the same problem previously using 3.23.53, which was solved after I 
have upgraded to a 3.23.55 RPM install. Switch on your logs and see 
what's happening.
