Editing to incorporate our Suggestions flat fee. Our typical customer does NOT want us editing any my.cnf or my.ini due to the nature this work. We have encountered dba's that are new and are willing to try any and everything with a single shutdown/restart.
Typically this would be a brand new effort and no where near a live application with customers/users counting on them being back on line in a few minutes. Another situation is the system was live and now the situation is desperate because hundreds of people that were using the system are now out of service.
