The server will disconnect idle connections after a while.  The wait_timeout variable
controls how many seconds it will wait.  You can set it for your connection when you
connect by issuing a query like:

SET SESSION wait_timeout=NNN;

Just give it a large enough value.

But also, since your program is going to be running continuously, there are many other
reasons it could lose the connection.  Your program should detect the error, and attempt
to re-connect.

Hello friends, I have  MySQL server version  " 5.0.51a-Ubuntu"  installed on Ubuntu 8.04
machine . I would describe briefly what we are doing .
Basically we have built a server that listen to Gprs connection from client  and accepts
data in form packets and inserts that data into MySQL database.I run three commands
.1.listening to Gprs connection and displaying all the received packets on the
terminal.2.Number of packets read will showed in Java serial forwarder (Tinyos for
reference )which listens on another port 3.command that invokes Java files  for inserting
data into database table .
Initially when i run the command  everything works fine and when he  receive packets he is
 able to insert data into table in MySQL database .

 He will still be listening on the port  (i.e he is running 24*7)Assume i receive data
after 12 hrs .i am experiencing the problem of .It may not necessarily be 12 hrs .
 If i have to insert data again i have to  recompile the code again and run all the
commands .
The error that is troubling is Result for query failed.  SQLState = 08003i googled the
error and found that this Sqlstate indicates connection does not exist .
I dont have any clues.Can any one help me please ?
