MYSQL too many connetions error message

Hello Experts,
while our new app is being developed by our provider
we are adjusting our legacy about to retire as much as possible.

I am getting error "odbc too many connections " from MySQL server
why is this?

Maybe is because in each piece of source we open a connection execute a command and close the connection?
Should I have one only connection all the session?

Each time I need to add/update or delete I follow the same steps
that is:

    con1 = SQLCONNECT("connex","root","root")
    R2 = SQLEXEC(con1,v2)

Works just fine until the " TOO MANY CONNECTIONS " error message.

What is your advice here?

Please check how you max connection does your instance support using the following command

mysql> show variables like "max_connections"

To increase the global number of connections temporarily, you can run the following from the command line:

set global max_connections = 200

then you check. hopefully this should solve your question

it was set to 151
your advice leads us to find the following...

SET GLOBAL interactive_timeout = 60;
SET GLOBAL wait_timeout = 60;

Now each sleeping connection is being erased by the server after 60secs
so we never reach the max.... this we just learned

Hope we are doing good and has no consequences..
So far .. problem solved !!
