JuanMaia to edit the BD settings you need the file /etc/mysql/my.cnf after editing you need to reload the BD systemctl restart mysql

And I checked document at https://mariadb.com/kb/en/innodb-system-variables/#innodb_buffer_pool_size and https://www.howtoforge.com/community/threads/how-to-change-innodb_buffer_pool_size-using-mariadb.79906/ On our server, here is a screenshot of conf files: http://prntscr.com/tsn70i To avoid any unexpected behaviour, Would you please let me know what I should input and which file should I touch please?
