How to set global innodb_buffer_pool_size?

Question

How to set the global innodb_buffer_pool_size mySQL variable? When I set it to system display I get this error:

ERROR 1238 (HY000):         


        

Answer 1

Look here innodb_buffer_pool_size documentation

In there it says this variable can be set in option-file (my.cnf) or on the command line when starting the server.

Also. I don't think you'll be able to assign the value of "system display" to this variable as it is a numeric. See the docs.
