Strange Mysql issue

Hi all,

I recently changed the name of my hostname from 'abc123' to 'abc456' (as an example).

I then added a user in my mysql database with the new host and removed references to the old users and hostname.

The strange thing is though, a process using the database still uses the old hostname!! Smilie

which then forced me to add the old names back into the database....

can anyone explain to me why this is the case and how i can ensure that all processes use the new hostname i.e. 'myuser'@'abc456' and NOT 'myuser'@'abc123'

NAME
mysql - text-based client for mysqld, a SQL-based relational database daemon SYNOPSIS
mysql [-B|--batch] [-#|--debug= logfile] [-T|--debug-info] [-e|--exec= command] [-f|--force] [-?|--help] [-h|--host= hostname] [-n|--unbuffered] [-p[pwd]] [--password=[pwd]] [-P|--port= pnum] [-q|--quick] [-r|--raw] [-s|--silent] [-S|--socket= snum] [-u|--user= uname] [-v|--verbose] [-V|--version] [-w|--wait] DESCRIPTION
