Server Command Options system. Applications that perform a lot of memory accesses may obtain performance improvements by using large pages due to reduced Translation Lookaside Buffer (TLB) misses. MySQL supports the Linux implementation of large page support (which is called HugeTLB in Linux). See Section 8.12.3.2, “Enabling Large Page Support” . For Solaris support of large pages, see the description of the  --super-large-pages  option. --large-pages  is disabled by default. The locale to use for error messages. The default is  en_US .

(Windows only) A  --local-service  option following the service name causes the server to run using the  LocalService  Windows account that has limited system privileges. If both  --defaults- file  and  --local-service  are given following the service name, they can be in any order. See Section 2.3.4.8, “Starting MySQL as a Windows Service” . 743 • --log-error[= file_name ] • --local-service • --lc-messages-dir= dir_name • --lc-messages= locale_name Command-Line Format --lc-messages=name System Variable lc_messages Scope Global, Session Dynamic Yes SET_VAR  Hint Applies No Type String Default Value en_US Command-Line Format --lc-messages-dir=dir_name System Variable lc_messages_dir Scope Global Dynamic No SET_VAR  Hint Applies No Type Directory name Command-Line Format --local-service Command-Line Format --log-error[=file_name] System Variable log_error Scope Global
